Problems solved by technology

However, light-curable resins have more unsaturated bonds and higher activity, and are susceptible to oxidation by oxygen in the air when the resin is cured, reducing the curing speed, and the ink film after curing is less flexible.
In addition, UV inks have been widely used in the printing industry. Existing UV inks often need to use monomer diluents as solvents, but the diluents themselves are toxic, irritating to human skin and not environmentally friendly.
Moreover, although UV inks are more environmentally friendly than traditional solvent-based inks, after the printed matter is discarded, the separation of the ink and the substrate during the recycling process is a key problem that is difficult to solve in the recycling process. The traditional UV ink will cause environmental pollution after being discarded. The pollution is also relatively serious, such as damage to soil, pollution of surface water, etc.

preparation example Construction

[0159] A preparation method of a biodegradable UV-curable ink, comprising the following steps:

[0160]Step 1. Mixing hydroxyl-containing alkyl (meth)acrylate and diisocyanate, so that the hydroxyl group of the hydroxyl-containing alkyl (meth)acrylate reacts with the isocyanate group of the diisocyanate, wherein the isocyanate The molar amount is greater than the molar amount of the hydroxyl group of the (meth)acrylic acid alkyl ester containing the hydroxyl group, and then the (meth)acrylic acid alkyl ester monomer that does not contain the hydroxyl group is added, so that the (methyl) Alkyl acrylate and the alkyl (meth)acrylic acid monomer containing hydroxyl group undergo a radical polymerization reaction to generate a urethane / (meth)acrylate copolymer with isocyanate groups;

[0161] Step 2, the water-soluble starch is reacted with diisocyanate, wherein the molar weight of the isocyanate group is greater than the molar weight of the hydroxyl group of the hydroxyl-containin...

Embodiment 1

[0199] a. Add 20g of isophorone diisocyanate into a clean four-neck flask with reflux condenser, thermometer and stirring device, and add 10g of hydroxyethyl methacrylate and 10g of hydroxypropyl methacrylate to the flask Mixture, use stirring device to open in this process and keep mechanical stirring state to make isophorone diisocyanate and methacrylate functional mixed monomer (the mixed monomer refers to hydroxyethyl methacrylate and hydroxypropyl methacrylate Esters) were kept in a uniformly mixed state, and stirred in a constant temperature water bath at 80°C for 3 hours to undergo a polymerization reaction;

[0200] The reaction formula of this step is mainly: -NCO+HO-→-NH-COO-

[0201] b. Mix 3.2g of OP-10 and 5.8g of sodium lauryl sulfate in 10g of deionized water, and then continuously drop the deionized water into the reaction system of step a, and stir and mix for 10 minutes 8g of methyl methacrylate, 4g of butyl acrylate and 7g of methacrylic acid mixed solution...

Embodiment 2

[0222] a. Add 39g of isophorone diisocyanate into a clean four-necked flask with reflux condenser, thermometer and stirring device. According to the principle of gradual polymerization reaction, add 19g of water-soluble starch to the reaction system and keep the temperature at 80°C. After mixing and stirring in a water bath for 2 hours, add 0.05g of di-n-butyltin dilaurate as a catalyst to fully react the water-soluble starch and diisocyanate for 30 minutes; reduce the temperature of the constant temperature water bath to 60°C, and add 4.5g of dimethylolbutyl Acid and 8g of N-methylpyrrolidone, stir and react at 60°C for 10 minutes, then raise the temperature of the water bath to 70°C and continue to stir and react for 10 minutes, then adjust the temperature of the constant temperature water area to 80°C and stir for 2 hours to generate terminal isocyanate groups Hydrophilic polyurethane prepolymer;

[0223] The reaction formula of this step is mainly: -NCO+HO-→-NH-COO-

Abstract

The invention discloses a compound resin, ink and a preparation method. A three-block vehicle composite resin comprises a first block, a second block and a third block, wherein the first block is a polyurethane-acrylate polymer block generated by polymerizing diisocyanate and hydroxyl-containing (methyl) acrylic acid alkyl ester and hydroxyl-free (methyl) acrylic acid alkyl ester; the second is a polymer block generated by polymerizing water-soluble starch and diisocyanate; the third block is a polymer block generated by polymerizing epoxy resin and diisocyanate. Ink formed by using the compound resin, pigment and assistant is high in solid content and stable in storage property.

Description

technical field [0001] The invention relates to a three-stage linking material composite resin, a biodegradable ultraviolet light curing ink and a preparation method thereof. Background technique [0002] Cigarette packs have always had strict requirements and harsh standards in packaging and printing. For printing inks, the requirements are even more stringent in terms of ink color, printing performance, environmental protection performance, anti-counterfeiting functions, etc., thus creating the cigarette pack printing technology. Almost means the status of the most advanced technology in the printing industry. As the State Tobacco Monopoly Administration successively promulgated industry standards on cigarette pack solvent residue limits and other relevant regulations on technology and materials used in cigarette pack printing. The cigarette pack printing industry pays special attention to the safety and environmental protection of printing inks. Ultraviolet light-curable...
