Problems solved by technology

Although two-component water-based coatings have better resistance and better stain resistance than one-component water-based coatings, the two-component coatings have disadvantages such as difficult construction, short open period, and certain toxicity, which limit Its large-scale application, and in many patents of stain-resistant coatings, can only achieve glossy effects, that is, the gloss at 60° angles is above 70°, and it does not solve the problem of matte stain resistance in actual household applications

Abstract

The invention relates to a water-based matte finishing varnish as well as a preparation method and application thereof. The water-based matte finishing varnish comprises the following components in parts by weight: 65-70 parts of silicone acrylic resin, 0.3-0.5 part of polysiloxane, 2-5 parts of wax dispersion, 0.1-26 parts of auxiliaries and the balance of water, totaling 100 parts. The water-based matte finishing varnish has excellent low-temperature (5 DEG C) film-forming performance on the premise that the addition amount of a coalescing agent is small and matting powder does not need to be added, has excellent matte property, anti-doodling property, stain resistance and scratch resistance after being formed into a film, is light in smell, ensures the low-temperature film-forming effect and is convenient for construction.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based matte finish varnish and a preparation method and application thereof. Background technique [0002] The technical requirements of architectural coatings are one base and two sides, while the traditional latex paint topcoats are poor in stain resistance, graffiti resistance and scratch resistance. Even if the score of stain resistance has passed the standard score, there will still be stain marks on the surface of the paint film, and the stain resistance is poor. Compared with traditional architectural coatings, the current interior latex paint has improved its stain resistance to a certain extent. However, for some stains, it may be wiped off immediately in a short time, but after more than two hours, it is almost difficult to wipe it off. Leaves very visible marks and has limited stain resistance. In addition, the coating formed by architectural coatings is gen...
