Part II: covered ink (ink scratch cards) close-up cover ink and screen printing ink is basically the same, by the film-forming resin, plasticizer, stabilizer, solvent, pigment composition. Cover ink is usually required to have a peelable, toughness, elasticity, acid corrosion, resistance to mechanical impact and better stability. Cover the preparation of ink, is the oxidation of castor oil and maleic anhydride resins and lanolin Stir hot solution, add the phthalate acid or five PCBs, and then a vinyl chloride resin dissolved in mixed solution and castor oil barium added, fully Stir obtained. The ink containing about 40% of the solid ingredients, viscosity 0.3Pa? S or more (20 degrees Celsius). Printing using solvent type photosensitive film, nylon or polyester mesh for screen printing, the ink film thickness of 20 ~ 40μm, viscosity regulators using butyl acetate. Dry one hour after printing to the next processing procedures need to be heated drying temperature shall not exceed 60 degrees Celsius. Do not over dry ink, to maintain flexibility and a lower adhesion, ease of processing and after stripping. If too dry will result in stripping difficulties. Cover the ink composition and characteristics are as follows: (1) resin. The main use of a vinyl chloride resin of the fluoride content of more than 65 percent of high-viscosity room. The resin film has the toughness, flexibility, weather resistance, water resistance and corrosion resistance to strong acid, but some adhesion is poor, this is just easy to peel, to adapt production, anti-strong acid corrosion, and a variety of processing cover layer necessary conditions. A vinyl chloride resin film is soft, low hardness, mechanical shock is weak, resulting in the limited scope of application. To improve this shortcoming, the general and other resins. Such: maleic anhydride resin, can improve ink hardness and anti polished, but also to reduce adhesion, not only to expand the range of applications, but also conducive to the spin-off after processing. In addition, you can join the lanolin, lanolin is a very complex composition wax ointment-like animal lipids have excellent lubricity, insoluble in water, but can absorb twice as much water and has a good slow The role of erosion and rust, not only can improve the peeling, peroxy-ethylene resin film can also maintain a permanent flexibility. (2) toughening agent. Toughening agent is used to improve the toughness of the vinyl chloride resin film. Commonly used dibutyl phthalate, the toughening effect, chemical stability, corrosion resistance decreased. For anti-corrosion cover layer of protection, it is best to use good corrosion resistance five PCBs. Reduce adhesion, easy to peel, also may be appropriate to join the castor oil, but the amount should not be too much, too much will affect the corrosion resistance. Join flexibilizer make the film chemical degradation, are added to control less than 20% of the amount of resin. (3) stabilizer. In order to prevent the vinyl chloride resin film in the light and heat under the influence of decomposition of hydrogen chloride, extend film life for long-term shelter, goods need to add stabilizer. Commonly used castor oil barium, a long-term stability. But after a temporary processing stripped down cover ink can also be without. (4) solvent. Low solubility of perchlorethylene, in order to achieve the appropriate screen printing and form a thick film ink with high viscosity and solid ingredients, you need to use ketones (acetone, cyclohexanone, ketone), esters (butyl acetate ), benzene (toluene, xylene), strong solubility of the solvent. (5) paint. Cover ink for intermediate processing, temporary shelter to the protective effect to complete the mission after the peel, not constitute the final product pattern coloring ink color with less stringent requirements, but according to the processing requirements to facilitate the observation of plus home pigment . Difficult to disperse the pigment in a vinyl chloride resin, easily dispersed pigment. To improve the cover layer effects, you can add talcum powder. Part III: grade clear plastic gravure printing ink in the domestic plastic flexible packaging industry on a large-scale enterprises account for only about 10% of small and medium-sized enterprises accounted for more than 90%. Advanced large plastic package enterprise printing press, printing speed (high speed printing presses), high quality product, volume, species specificity, with the ink of higher quality and large amount of, generally up to fixed production two to three ink manufacturers ink. However, many in small plastic package enterprise presses, although in recent years, many manufacturers have updated their equipment and poor production varieties are numerous, but small quantities, small quantities. Thus higher than hybrid ink using the ink, there is no fixed ink manufacturers, generally as the preferred low-cost ink. Plastic flexible packaging into food packaging, salt packaging, cosmetic commodity packaging, pharmaceutical packaging, paper packaging, garment packaging and so on, including food packaging label is the compound where India ink-based, some of the candy wrappers Table India ink; cooking and packaging using high-temperature cooking ink, general vacuum packaging polyester ink; dairy packaging to use the water, acid, the temperature of the ink. Pharmaceutical packaging and cosmetic packaging polyester ink. Some manufacturers use salt packaging surface printing inks, and some manufacturers use polyester ink. Commodity packaging, paper packaging and apparel packaging multi-surface ink, but the table printed white ink is a special, smooth scratch resistance, anti-adhesion of the ink. More and more as the packaging market, quality improvement, the use of the compound where India ink. Plastic ink price at high, medium and low grades. General plastic gravure printing ink market price: cooking ink the average price of 50-60 yuan; polyester ink, the average price of 25-30 yuan; compound where India ink, the average price of 18-25 yuan; dairy The ink used on the average price of 25-30 yuan. The price listed above is generally acceptable to all packaging plant price, but also to ensure the quality of the ideal price. Large packaging companies are big users of the ink, domestic ink market is a small market; medium-sized packaging enterprises in ink users, ink manufacturers fight for the ideal market; many small package business is a small user , but in the current domestic market. The largest user of ink usage, price discounts, the amount of pressure shall back section of the long duration of the ink manufacturers to break into a strong financial background, the strength, the initial investment, the late risk. The user to facilitate sales management to fight the sale of the ideal object, but the ink factory needs sales policy support and long-term patient human input. The large number of small users in the current domestic ink sales market, it requires a lot of manpower, must rely on after-sale multi-faceted services. Now the majority of domestic ink company is not on the plan. Since 2003, the chemical raw materials price increases and a long duration, ink manufacturers not only profit decreased and some solvents are also in short supply, causing manufacturers to produce low priced ink no ink available. Is currently a large number of plastic packaging business of raw materials - polyethylene particles substantially long period of price increases, resulting in many packaging plant production is not normal, the amount of ink drop. Ink sales market more competitive, each ink manufacturers have to be prepared to invest more funds and manpower, reforms to improve their marketing policies to strengthen after-sales service. In short, the consolidation of large users needs of the development funds, the small user market development need to increase investment in manpower and transport. Rich market prospects of the liquid crystal ink ink, is a very promising new ink material to be developed. The printing wide range of applications, its function is mainly used for the temperature display, hair color changes in two directions. Temperature display: thermometer, body temperature, automatic temperature recorder, testing machinery and testing equipment, the substrate temperature display requirements. At present, foreign countries also use the LCD printed tape as a one-off temperature test meter. Changes in hair color: advertising, label, arts and crafts, medals, jewelry and other ornaments, and security printing products. Such as for the print calendar pictures will show different color with the temperature changes of the four seasons; printed children book, change the screen color touch with the children pointing; printed trademarks, wrapping paper, etc., attached to the span of the product according to the pattern of color change, understand the change of the quality of the built-in items such as candy wrappers, bright screen, change the dark, as soon as possible to eat the candy, or dissolved. Liquid crystal patterns can be printed on the container show the items in the container humidity, expensive, sensitive to heat, cold big-ticket items, LCD printed cue cards can be used as the storage temperature. As for the liquid crystal ink as security inks, the characteristics of the LCD temperature change, and now has to play a significant role in the field of anti-counterfeiting packaging and decoration of its security effectiveness is relatively ideal. LCD ink from the United States in the 1970s. Later, with its mature technology and printing market continues to expand, the liquid crystal ink printing in the United States, Japan and other countries quickly developed, the scope of application is also increasing in. LCD ink production methods from the point of view, belongs to the microcapsule structure of the type of ink from the application point of view, a heat-sensitive temperature-induced change in the security printing ink ink areas, but the characteristics of the liquid crystal ink speaking, the main characteristics of the LCD temperature change . Liquid crystal ink is mainly composed of water-soluble resin, liquid crystal capsules, additives, binders, defoamers, will be closed in the microcapsules in the liquid crystal and additives dispersed in the link compound from the preparation of. It is based on the temperature of the ink in the liquid crystal caused by the ordered changes in the molecular direction, to a specific wavelength of visible light selective reflection, absorption of the optical properties of the other wavelengths of light showing the color changes, rather than ink pigments constitute the color graphic. Liquid crystal by the irradiation of natural and artificial white and colored light of a wavelength, due to refraction and strengthen the reflection into a short wavelength colors (red - green - blue change), as the temperature rises, the long-wavelength color the fineness of the mechanism of its LCD is LCD specific wavelengths of light selective reflection from. The LCD must be printed in black or dark background, the LCD can reflect the negative 100 to positive 700 degrees Celsius. The accuracy is 0.50 degrees Celsius. Due to the arrangement of the liquid crystal molecules is not as solid as crystal structure, it is very susceptible to external stimuli such as electric and magnetic fields, temperature, stress, and adsorption of impurities, changes to a variety of optical properties. The LCD Ink applied LCD with such features. Since the liquid crystal between the organic compounds in the liquid and crystal, it can not be like ordinary ink spots, added directly connect compound. Free LCD of material pollution, to ensure that the coloring effects, and therefore need the LCD wrapped in the micro-spherical capsule, and then mixed with binders to produce the so-called 'microencapsulation' inks. LCD ink microcapsules and microcapsules in the foam, the smell of ink. Blowing agent (foaming ink microcapsules or low boiling point liquefied gas) was heated, the blowing agent within the microcapsules release large amounts of gas (or low boiling point liquefied gas expansion glue) so that the microcapsules volume increases from the foam role. In addition, in the foam ink pigments, printing a colorful foam graphics, and with the dual function of foam fineness. Characteristics of the microcapsules, the smell of ink in printing is not crushing damage, printing into products that require nails, pencils and other press and tear to make it very easy to destroy but to achieve the purpose of emitting a scent. LCD ink microcapsules by connecting the material inside the capsule liquid crystal solid attached to the ink. LCD ink can be screen or gravure printing, screen printing better. LCD printing technology, the key is the ability at different temperatures showed bright color LCD, and color temperature threshold into the series. Liquid crystal microcapsules to do a small and uniform, transparent and thin wall, mixed with ink, requiring solvent stable, reliable, long life; the printing process but also ensure that the liquid crystal microcapsules are not crushed; surface covered with a protective film. LCD ink printing to note the following: (1) plates equipped with a sufficient amount of ink to the ink to be uniform, half-way is best not to fill ink to prevent foaming; (2) Printing block network blistering, to be shut down immediately ruled out, thoroughly cleaned with alcohol-water; (3) printing pressure should be moderate. Pressure is small, less than the amount of ink on the printed substrates; excessive pressure will cause the liquid crystal capsule rupture, the effect of hair color; (4) for the printing part of the obvious hair color, printed background color choice of black or dark colors. The bottom of the water-soluble ink, and can also be used in organic solvent ink. The printing method available screen printing, offset printing, gravure printing. When the use of organic solvents, ink, after printing must fully dry, the ink film no residual organic solvent, otherwise the reaction with the liquid crystal, the effect of hair color; (5) to pay attention to the ink to be smooth smooth ink film thickness control to 15 ~~ 35μm in order to improve the effect of hair color; (6) printing color sequence arrangement. Can be black (or dark color) ink printing background, and then the liquid crystal ink printing the desired pattern; first and then water-soluble black (or dark color) ink printing requirements negative patterns covering the end of the liquid crystal ink printed over. LCD ink printed post-processing: (1) drying the best way to dry naturally, can also be about 40 degrees Celsius hot air drying, do not accelerate the heating high-temperature sharp dry; (2) printed materials stacked not weight. Dry, try not to accumulation of overlap too much, off the CD, etc. should not be increased over a large partial pressure, in order to avoid the liquid crystal microcapsules were crushed; (3) the use of liquid crystal ink should be determined according to the intended use color temperature range and considered according to use LCD durability. In order to improve the ink surface abrasion resistance, temperature resistance, and separated from the gas as well as to maintain its gloss, surface coating UV varnish or laminating process.
