Novel heat-insulating and self-cleaning environmentally friendly coating

Abstract

The invention discloses a novel heat-insulating and self-cleaning environmentally friendly coating. The coating comprises, by mass, 30-65 parts of an acrylate emulsion, 25-55 parts of a silicone-acrylic emulsion, 5-15 parts of fluoroalkylsiloxane, 5-15 parts of a glass fiber filler, 5-10 parts of mica powder, 3-8 parts of talcum powder, 3-10 parts of ceramic powder, 5-15 parts of nanometer titanium dioxide, 5-10 parts of nano-alumina, 5-10 parts of nano-graphite powder, 2-5 parts of a silane coupling agent, 1-3 parts of a viscosity regulator, 1-3 parts of a leveling agent, 1-3 parts of a dispersant and 0.5-1.5 parts of a defoaming agent. The novel heat-insulating and self-cleaning environmentally friendly coating is used as an environmentally friendly exterior wall coating, and has the advantages of good heat insulating performance, good anti-fouling performance, good self-cleaning performance, long storage period, good stability and good use effect.

Description

technical field [0001] The invention relates to the field of architectural decoration, in particular to a novel heat-insulating self-cleaning environmental protection paint. Background technique [0002] The paint used for decoration is widely used and used in a large amount. However, due to too many chemical synthetic substances, especially formaldehyde, it seriously pollutes the air and even causes users to suffer from diseases. In particular, with the implementation of my country's housing industrialization and building energy conservation, the demand for high weather-resistant self-cleaning exterior wall coatings is increasing. At the same time, this self-cleaning exterior wall coating is required to have the following characteristics: not easy to attach pollution, or attached Pollutants can be removed by external natural conditions such as rainwater and wind. Therefore, improving the stain resistance of building exterior walls has become an important index to measure th...
