Wear-resistant high-transmittance super-smooth PU open-type matte varnish and preparation method thereof

Abstract

The invention belongs to the technical field of coatings. The wear-resistant high-transmittance super-smooth PU open type matte varnish comprises a component A, a component B and a diluent, and the mass ratio of the component A to the component B is 10:5-6; the component A comprises hydroxy acrylic resin, a wetting dispersant, polyamide anti-settling slurry, an antioxidant, an ultraviolet absorber, aldehyde ketone resin, wax powder, glass powder, extinction powder, CAB cellulose, an ether ester solvent, an ester solvent, an antifoaming agent, a leveling agent and a drier; and the component B comprises n-butyl acetate, a dehydrating agent, aromatic polyisocyanate and aliphatic polyisocyanate. The wear-resistant high-transmittance super-smooth PU open type matte varnish is high in paint film hardness, has good yellowing resistance, chemical resistance, scratch resistance and wear resistance, is applied to the surface of technical wood, and is good in solid wood texture, high in transparency, clear, not bloated and good in matte effect.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a wear-resistant, high-transparency, super-smooth PU open matte clear finish and a preparation method thereof. Background technique [0002] With the improvement of people's material life and cultural living standards, the living environment and home taste are also improved, and the choice of furniture materials is also more diverse. In recent years, high-tech veneer sheets have been favored by the majority of furniture manufacturers, occupy an indispensable position in home furnishing production, and are also favored by consumers. As a new type of wood, the technical veneer, which adopts scientific and technological means to beautify the logs, meets people's demand for excellence in the use of wood. Technology veneer is also called beautification board, technology board, composite board, artificial veneer, technology veneer can be made very thin, easy to stick, low...

AI Technical Summary

Problems solved by technology

However, the technology veneer is extremely easy to turn yellow after being processed by technology or other technical means, the surface effect is poor, and there is no hand feeling. The easy yellowing of the original technology veneer also brings troubles to furniture manufacturers and home improvement construction teams: The paint film is relatively bloated, without a real wood feel, the gloss is too high, the log feel is poor, the transparency is poor, the surface is foggy, the paint film is not resistant to scratches, and the hardness is low
