Problems solved by technology

Due to the use of air spraying for spraying PU matte clear topcoat, the utilization rate of coating paint is low, and insufficient atomization causes the paint film to become old after film formation, the gloss is uneven, and it takes multiple coats to meet the film thickness requirements, etc. Disadvantages: When painting, the paint mist will volatilize a large amount of organic volatiles and free isocyanates, which will seriously pollute the atmospheric environment and cause harm to the health of construction workers
And the flexibility, scratch resistance, impact resistance, hardness, abrasion resistance, luster, transparency of existing drench coating PU matte clear topcoat are all relatively poor

Abstract

The invention relates to an environment-friendly curtaining odor-removing PU matted varnish and a preparation method of the environment-friendly curtaining odor-removing PU matted varnish, and belongs to the technical field of wooden coating manufacturing. The environment-friendly curtaining odor-removing PU matted varnish is prepared by mixing component A, component B, and component C according to the weight ratio of 1: 0.5: 0.4-0.7; the component A is composed of fatty acid modified odor removal alkyd resin, short-oil castor oil alkyd resin, polyamide wax anti-sediment, wetting dispersant, flatting agent, antifoaming agent, modified polyethylene wax powder, matt powder, propylene glycol monomethyl ether acetate, cyclohexanone, ethylene glycol diacetate, 50% by mass of nitrocotton fluid, and n-butyl acetate; the component B is composed of aliphatic series polyisocyanate, TDI tripolymer curing agent, TDI prepolymer, and n-butyl acetate; the component C is composed of xylene, n-butyl acetate, propylene glycol monomethyl ether acetate, acetate, and ethylene glycol diacetate. The coating has strong adhesive force, good transparency, high fullness, good flexibility, good scratching resistance, uniform gloss, stability and impact-resistance, and good waterproof and chemical resistance.

Description

technical field [0001] The invention relates to an environmentally friendly deodorizing PU matt varnish and a preparation method thereof, belonging to the technical field of wood coating manufacturing. Background technique [0002] Modern living furniture and decorations are getting more and more attention in people's lives. With the prosperity of the furniture industry in the past 30 years of reform and opening up, the corresponding wood lacquer coatings have also been further improved. In order to better show the natural characteristics of wooden furniture such as textures and lines, the requirements for paint decoration have also been raised. There are also product requirements for the transparency, leveling, flatness, and gloss uniformity of the paint film. At the same time, the paint film is easy to be scratched and worn during furniture transportation, storage, use, and maintenance. , also put forward new requirements. [0003] According to different brushing proper...
