Problems solved by technology

[0005] In the existing paint market, diatomite and negative ion powder are widely used, but in the general use process, its function is single, and in the southern region with high humidity, long-term humid environment is easy to breed bacteria, and diatomite has Adsorption function, compared with ordinary coatings, it is more prone to mold and bacteria, and does not have flame retardant properties. Therefore, with the improvement of people's needs, the production of environmentally friendly and multi-functional coatings is more suitable for market needs

Abstract

The invention discloses a flame-retardant mildew-proof powder coating based on environmental protection. The coating comprises the following raw materials in parts by weight: 60 to 80 parts of acrylicresin, 12 to 20 parts of polyvinyl alcohol, 2 to 6 parts of diatomite, 10 to 15 parts of titanium dioxide, 0.6 to 1.5 parts of negative oxygen ion powder, 4 to 7 parts of a flame-retardant mildew preventive, 1 to 3 parts of magnesium stearate, 0.5 to 1.5 parts of a leveling agent and 1 to 1.5 parts of benzoin. According to the invention, titanium dioxide particles, the negative oxygen ion powderand the flame-retardant mildew preventive can be uniformly adsorbed in the diatomite, and in the powder coating obtained through melt extrusion, a brushed coating cannot fall off due to scrubbing; thetitanium dioxide serves as a photocatalyst, so negative oxygen ions can be released for a long time to purify and sterilize indoor air, peculiar smells in the air can be adsorbed and decomposed, indoor smells are improved, and the functions of humidifying and deodorizing are achieved; and the prepared flame-retardant mildew preventive is extruded into diatomite layer grids in a melting manner, sothe flame-retardant mildew-resistant performance of the coating can be maintained for a long time, and the flame-retardant mildew preventive is suitable for commercial production and application.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an environmentally friendly flame-retardant and mildew-proof powder coating. Background technique [0002] With the continuous improvement of people's awareness of environmental protection, the concept of green decoration has attracted more and more attention. According to statistics, the time people spend in various indoor environments (living rooms, offices, public places and vehicles, etc.) 70%-80% of the active time. While the airtightness of the residence is constantly improving and the air permeability is decreasing, people have used too many decorative materials that continuously release harmful chemicals (formaldehyde, organic matter, etc.) when carrying out interior decoration, which is harmful to people's health. [0003] Diatomaceous earth is a kind of biogenic siliceous sedimentary rock, which is mainly composed of the remains of microbial plants (a sing...
