Problems solved by technology

[0003] Water-based matte varnish is a kind of wood varnish with excellent comprehensive performance, which is widely used in wood decoration. After the conventional product is mixed with paint, due to the characteristics of ordinary resin emulsion, the crosslinking degree cannot be designed too high, and the hardness is difficult to increase. Sexuality also worsens with increasing hardness

Abstract

The invention provides environment-friendly water-based transparent matte clear finish paint. The environment-friendly water-based transparent matte clear finish paint is prepared from, by weight, 35%-50% of fluorocarbon modified acrylic emulsion, 20%-30% of styrene-acrylic emulsion, 0.3%-0.5% of wetting and dispersing agent, 1%-6% of matte powder, 4%-9% of coalescing agent, 0.3%-0.4% of thickening agent, 1%-3% of antifreezing agent, 0.3%-0.5% of anticorrosion and bactericidal agent, 0.3%-0.5% of antifoaming agent, 0.3%-0.5% of flatting agent, 0.2%-0.6% of PH modifier and 4%-16% of water. The environment-friendly water-based transparent matte clear finish paint is high in adhesive force and hardness, resistant to high temperature, good in chemical resistance, high in yellowing resistance and easy to spray, and meets the environment-friendly requirements of customers for high environment friendliness, low smells and low pollution.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an environment-friendly water-based transparent matt clear finish and a preparation method thereof. Background technique [0002] Modern living furniture is getting more and more attention in people's life. With the vigorous development of the furniture industry in the past 30 years of reform and opening up, the supporting 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 the decoration of the paint have also been raised, and the transparency, leveling, flatness, gloss and color retention of the paint film have also been improved. The product requirements were put forward, and new requirements were also put forward for the easy scratching and wear of the paint film during the transportation, storage, use and maintenance of furniture. [0003...
