Problems solved by technology

[0004] Traditional solvent-based varnish and ordinary varnish need to use organic solvents in the production process, and there are more organic volatilities during printing and drying, which is very harmful to operators and pollutes the environment
Moreover, the drying speed is slow and the production efficiency is low
Furthermore, the energy consumption is high and there is a waste of resources

Embodiment 1

[0024] This example describes a method for preparing environmentally friendly UV varnish for paper printing. During the entire process, the temperature is controlled below 70°C, and the process steps are as follows:

[0025] First, 20 kg of modified epoxy acrylate, 15 kg of polyurethane acrylate, 7 kg of hexanediol diacrylate, 7 kg of tripropylene glycol diacrylate, 4 kg of polyethylene glycol di(β -4-[p-(2-dimethylamine-2-benzyl) butyrylphenyl] piperazine) propionate, 7 kg of P-115 tertiary amine acrylate mix, high-speed stirring, stirring speed is 800-1500 rpm, control the temperature below 70°C, fully dissolve until transparent, and obtain a transparent liquid.

[0026] Then, 1.5 kg of fluorinated polyethylene wax was pre-mixed into a slurry with 6 kg of pentaerythritol hexaacrylate. Disperse at high speed, stir for 0.5h, the stirring speed is 1200-2000 rpm, stir evenly and then set aside, control the temperature not to exceed 50°C, and obtain a slurry-like functional addi...

Embodiment 2

[0029] This example describes a method for preparing environmentally friendly UV varnish for paper printing. During the entire process, the temperature is controlled below 70°C, and the process steps are as follows:

[0030] First, 18 kg of modified epoxy acrylate, 7.5 kg of pentaerythritol hexaacrylate, 10 kg of trimethylolpropane triacrylate, 1 kg of ITX (isopropyl thioxanthone), 1 kg of polybutylene Diol 250 bis-(2-carboxymethoxythioxanthone) ester and 9 kg of P-115 tertiary amine acrylate are mixed, stirred at high speed, the stirring speed is 800-1500 rpm, and the temperature is controlled below 70°C , fully dissolved completely until transparent to obtain a transparent liquid.

[0031] Then, add 7.5 kg of hexanediol diacrylate to the transparent liquid, cool down to below 50°C, then add 0.6 kg of silicon-free defoamer, 0.8 kg of polyether siloxane copolymer , stirring and dispersing for 10 minutes at a stirring speed of 800 rpm to obtain environmentally friendly UV varn...

Embodiment 3

[0033] This example describes a method for preparing environmentally friendly UV varnish for paper printing. During the entire process, the temperature is controlled below 70°C, and the process steps are as follows:

[0034] First, 12 kg of modified epoxy acrylate, 19 kg of polyurethane acrylate, 7 kg of trimethylolpropane triacrylate, 7 kg of polyethylene glycol di(β-4-[p-(2- Dimethylamine-2-benzyl) butyrylphenyl] piperazine) propionate, 20 kg of P-115 tertiary amine acrylate mixed, high-speed stirring, stirring speed is 800-1500 rev / min, controlled When the temperature is below 70°C, it will be completely dissolved until it becomes transparent, and a transparent liquid will be obtained.

[0035] Then, 0.5 kg of fluorinated polyethylene wax was pre-mixed into a slurry with 3 kg of pentaerythritol hexaacrylate. Disperse at high speed, stir for 0.5h, the stirring speed is 1200-2000 rpm, stir evenly and then set aside, control the temperature not to exceed 50°C, and obtain a slur...

Abstract

The invention relates to paper printing environmental-friendly UV (Ultraviolet) gloss oil and a preparation method thereof, belonging to the technical field of chemical industry. The paper printing environmental-friendly UV gloss oil is used for glazing various kinds of paper packing paper, such as cigarette labels, wine labels, and the like, and comprises the following raw materials in parts by weight: 10-40 parts of modified epoxy acrylate, 10-60 parts of active monomers, 2-10 parts of macromolecular photoinitiators, 1-20 parts of auxiliary initiators, 0.1-1 part of defoaming agents and 0.1-1 part of flatting agents. The invention has the advantages of reasonable formula, high gloss, good abrasion resistance, low volatile matter content, energy saving, environmental protection, low costand stable product quality.

Description

technical field [0001] The invention relates to an environmentally friendly UV varnish for paper printing and a preparation method thereof, which is used for glazing paper packaging papers such as cigarette labels and wine labels, and belongs to the technical field of chemical industry. Background technique [0002] With the progress of society and the transformation of people's consumption concept, the safety, sanitation and environmental protection of consumer goods are increasingly concerned by the whole society. Over the years, the tobacco industry has always adhered to the people-oriented principle and strived to protect the legitimate rights and interests of consumers. Especially in recent years, the tobacco industry has firmly established the common values ​​of "national interests first" and "consumers first". To protect the interests of consumers and avoid potential environmental pollution, the State Tobacco Monopoly Administration organized and implemented the YC / T...
