Abstract

The invention discloses novel water-based finishing paint. The novel water-based finishing paint is prepared from, by weight, 52-64 parts of crylic acid water-based emulsion, 10-18 parts of an organicsolvent, 3-7 parts of modified wax emulsion, 8-12 parts of an aid, 10-17 parts of filler and 30-50 parts of water. The novel water-based finishing paint is good in mildew resistance, high in hardness, good in anti-scratching performance, safe, free of toxins, fast in coating drying and simple in subsequent maintenance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a novel water-based finish paint. Background technique [0002] Topcoat is the final coating of painting, and it is the last layer applied in building wall decoration. The overall effect after decoration is reflected through this layer. Therefore, there are high requirements for the materials used, not only to have good chroma and brightness, but also to have good pollution resistance, aging resistance, moisture resistance, mildew resistance, and non-polluting, safe and non-toxic , No fire hazard, convenient construction, fast drying of coating film, good gloss and color retention, good air permeability and so on. It has decorative and protective functions, such as color, gloss, texture, etc., and it also needs to be resistant to harsh environments. [0003] In some existing topcoats, due to the need for many functions, such as mildew resistance, fire resistance, aging resista...
