Problems solved by technology

As a kind of UV curing paint, UV spraying matt finish paint is developing rapidly in the field of wood coatings. It has the effect of preventing pollution and saving energy. It has excellent chemical and physical properties, fast curing characteristics, and high solid content. It is being widely adopted and used in the field of furniture paint, and its performance can better meet the chemical corrosion resistance, and its paint film performance is also more excellent. The problem of poor transparency leads to the fact that the paint film formed after being applied on the wood cannot better show the texture and color of the wood itself

[0057] A kind of UV spraying high translucency matte varnish, it is prepared by following method:

[0058] (1) Prepare 20% polyamide wax anti-settling slurry: put 60 parts of xylene into the dispersion tank, then put 20 parts of polyamide wax into it, wash the side of the tank with 5 parts of xylene, and disperse 15 parts at a speed of 1200 to 1500 rpm. ~20 minutes until the fineness is ≤25μm, stop the machine and add the remaining 15 parts of xylene, stir evenly at a speed of 600-800 rpm for 8-10 minutes, filter with a 200-mesh filter, and put it into a bucket for use;

[0059] (2) Preparation of 35% nitrocellulose solution: put 10 parts of butyl acetate, 49 parts of ethyl acetate, and 1 part of nitrocellulose anti-yellowing agent into the dispersion tank and stir for 5-6 minutes at a speed of 600-800 rpm. Slowly put 35 parts of nitrocellulose into the dispersing tank, stir at a speed of 600-800 rpm for 5-6 minutes, then wash the edge of the tank with the remaining part of bu...

Abstract

The invention discloses a UV (ultraviolet) spraying high-transmittance matte varnish comprising a main paint and a UV reactive diluent, wherein the weight ratio of the main paint to the UV reactive diluent is 1: (0.3-0.4), and the main paint is prepared from the following raw materials: an epoxy acrylate prepolymer, a urethane acrylate prepolymer, hydroxyethyl methacrylate, a photoinitiator, a dispersing agent, an antifoaming agent, a rheological agent, extinction powder, trimethylolpropane triacrylate, dipropylene glycol diacrylate, polyamide wax anti-settling slurry, nitrocotton liquid, cellulose acetate butyrate liquid, an acrylate leveling agent and an organic silicon leveling agent. The UV reactive diluent is prepared from the following raw materials: hydroxyethyl methacrylate, trimethylolpropane triacrylate and dipropylene glycol diacrylate. The UV spraying high-transmittance matte varnish has good extinction property and also has good transparency.

Description

technical field [0001] The invention relates to the technical field of wood coating manufacturing, in particular to a UV spraying high-transparency matte clear finish and a preparation method thereof. Background technique [0002] At present, the curing methods of paint include traditional natural drying and UV curing. Traditional natural drying takes a long time to cure, and the solvent is volatile and not environmentally friendly. UV curing is to expose the paint surface to be cured to UV radiation, and harden and dry the paint through ultraviolet radiation with a wavelength of 200nm to 450nm to achieve the purpose of curing, and its production efficiency is high. As a kind of UV curing paint, UV spraying matt finish paint is developing rapidly in the field of wood coatings. It has the effect of preventing pollution and saving energy. It has excellent chemical and physical properties, fast curing characteristics, and high solid content. It is being widely adopted and use...
