Abstract

The present invention relates to the technical field of water-based paint, especially the technical field of matte paint, and specifically discloses a matte finish varnish, which comprises the following components in parts by mass: 50-60 parts of water-based acrylic matte emulsion, 30 parts of deionized water ~46 parts, substrate wetting agent 0.05~0.1 parts, defoamer 0.1~0.2 parts, propylene glycol 1~2 parts, film forming aid 1~2 parts, thickener 0.2~0.4 parts. The matte finish varnish of the present invention has the advantages of good gloss and good dispersibility, is not easy to form stratification and precipitation, is stable in storage, and avoids the problem of easy mold and whitening when using matte powder.

Description

technical field [0001] The invention relates to the technical field of water-based paint, especially the technical field of matte paint. Background technique [0002] The matte finish varnish can protect the base coating (water-in-water multi-color coating, real stone paint, texture coating, etc.), and at the same time improve the performance of the base coating, such as water resistance, stain resistance, scrub resistance, etc. . But at present, most matt finish varnishes in my country are mainly matte powder matting, that is, matte powder is used as a matting agent in the paint, and its addition amount is about 1 to 1.5%. [0003] The main component of dumb powder is silicon dioxide, and when the addition amount is 0.5-1%, it is easy to form precipitation in the paint during storage. During construction, in order to avoid storage stratification, the viscosity must be increased, resulting in excessive construction dosage. In addition, the matte powder and acrylic emulsio...
