Problems solved by technology

After the conventional UV coating is cured, it is easy to produce small molecular inert substances when the initiator is cracked. This part of the cracked product cannot participate in the photocuring reaction, causing volatilization into the air or remaining inside the paint film, affecting the health of production workers, and even damage to consumers, for this reason, how to solve this problem is imminent

Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with examples, and the examples are only preferred implementation cases of the present invention, and are not limitations of the present invention.

[0024] The raw materials are operated according to the steps described in the specific preparation method above:

[0025] A. First put the resin, dispersant, and part of the active diluent in the formula into the reactor, and disperse for 20-30 minutes at a speed of 800-1200 rpm;

[0026] B. Add defoamer and leveling agent in proportion to disperse for 20 minutes at a speed of 1000-1200 rpm;

[0027] C. Throw in photoinitiator, and disperse for 10 minutes at a speed of 800-1000 revolutions per minute;

[0028] D. Add matting powder according to the proportion, and disperse for 30 minutes at a speed of 1200-1800 rpm;

[0029] E. Put in all the UV active diluents, and disperse for 15 minutes at a speed of 600-800 rpm. After passing the test, use a 300-...

Abstract

The invention belongs to the field of the chemical industry and particularly discloses ultraviolet-curing odorless laser-coating matt finishing paint and a preparation method thereof. The paint is single-component paint and prepared from, by weight, 30%-50% of epoxy acrylate resin, 5%-15% of hyperbranched polyester acrylate resin, 1%-2% of a photoinitiator, 0.3%-3% of a dispersing agent, 0.1%-0.5%of an antifoaming agent, 0.2%-0.5% of a flatting agent 1, 0.1%-0.3% of a flatting agent 2, 10%-15% of matting powder and 30%-40% of a UV active diluting agent. The ultraviolet-curing odorless laser-coating matt finishing paint is odorless, high in hardness and wear resistance, good in hand feeling and uniform and soft in gloss.

Description

technical field [0001] The invention relates to the technical field of chemical industry, more specifically, the invention relates to an ultraviolet light-cured all-clean taste laser-coated matte finish and a preparation method thereof. Background technique [0002] UV paint is the English abbreviation of Ultraviolet Curing Paint, that is, ultraviolet light curing paint. The curing principle is that the photoinitiator absorbs ultraviolet light and then decomposes when the paint is irradiated by ultraviolet light, and generates free radicals to crosslink with photocurable resin and reactive diluent , It can be solidified into a film in an instant. It has the characteristics of environmental protection, high efficiency and low cost. After the conventional UV coating is cured, it is easy to produce small molecular inert substances when the initiator is cracked. This part of the cracked product cannot participate in the photocuring reaction, causing volatilization into the air ...
