Problems solved by technology

[0004] At present, the oligomers used in UV curing varnish are mainly epoxy acrylic resins. Epoxy acrylic resins have many advantages, such as strong adhesion, chemical corrosion resistance, high hardness and high adhesion, but bisphenol A epoxy acrylic resins The resin coating film is brittle and easily shrinks during curing. The UV varnish made of this type of oligomer, if the paper is polished and then subjected to processes such as folding leaves and beer line indentation, the paper is easy to burst and cannot be stretched. To protect the paper very well

Embodiment 1

[0026] Take 100g A1 resin, add 0.4g defoamer, 20g tripropylene glycol diacrylate, 15g 1,6-hexanediol diacrylate, stir well, then add 8g benzophenone, 2g 1-hydroxy-cyclohexyl Benzophenone and 8g active amine were stirred at high speed, and finally 0.6g leveling agent was added to obtain UV-curable varnish.

Embodiment 2

[0028] Take 100g A2 resin, add 0.4g defoamer, 20g tripropylene glycol diacrylate, 15g 1,6-hexanediol diacrylate, stir well, add 8g benzophenone, 2g1-hydroxy-cyclohexyl Benzophenone and 8g active amine were stirred at high speed, and finally 0.6g leveling agent was added to obtain UV-curable varnish.

Embodiment 3

[0030] Take 100g A3 resin, add 0.4g defoamer, 20g tripropylene glycol diacrylate, 15g 1,6-hexanediol diacrylate, stir well, add 8g benzophenone, 2g1-hydroxy-cyclohexyl Benzophenone and 8g active amine were stirred at high speed, and finally 0.6g leveling agent was added to obtain UV-curable varnish.

[0031] Properties of UV Curable Varnish

[0032] Use the UV-curable varnish prepared in Examples 1-3 respectively, draw and coat the paper printed with ink with a 4 μm wire bar, and cure with UV light. The performance inspection and evaluation of the light film are carried out according to the following methods. The performance is shown in Table 2 .

Abstract

The invention discloses UV curing gloss oil with excellent explosion-proof performance. The UV curing gloss oil with the excellent explosion-proof performance is prepared from, by weight, 80-120 parts of organic dibasic acid modified epoxy acrylate active oligomer, 0.2-0.6 part of antifoaming agents, 10-30 parts of tripropylene glycol diacrylate, 10-20 parts of 1,6-hexanediol diacrylate, 4-12 parts of diphenyl ketone, 1-3 parts of 1-hydroxy-cyclohexyl benzene ketone, 4-12 parts of active amine, 0.3-0.9 part of flatting agents and 5-10 parts of water; the organic dibasic acid modified epoxy acrylate active oligomer is prepared from, by weight, 150-250 parts of E-51 epoxy resin, 30-50 parts of organic dibasic acid, 20-30 parts of succinic acid, 0-30 parts of adipic acid, 2-30 parts of glutaric acid, 0-15 parts of azelaic acid, 0-15 parts of sebacic acid, 30-70 parts of acrylic acid, 1.2-4.5 parts of triphenylphosphine, 0.3-1.8 parts of 4-methoxyphenol and 5-10 parts of water. Compared with epoxy-acrylic resin used by ordinary UV gloss oil, the UV curing gloss oil has the excellent explosion-proof performance, and due to the fact that the content of benzene rings in molecules is decreased, the anti-yellowing performance is promoted to some extent.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a UV curable varnish with excellent explosion-proof line and a preparation method thereof. Background technique [0002] Water-based glazing and UV glazing are two commonly used surface treatment processes in the field of printing and packaging. With the increasingly strict control of the VOC content of coatings in China in recent years, water-based varnishes have become the mainstream of printing varnishes. Water-based varnish refers to an environmentally friendly coating product that uses water as a carrier and is coated on-line with a printing machine or off-line with a glazing machine to increase the gloss, water resistance, and abrasion resistance of paper-based printed matter. At present, coating and glazing technology has been adopted by more and more printing manufacturers, which has led to a continuous increase in the demand for varnishes. Because water-bas...
