A heat-insulating and heat-preserving water-based coating with the function of purifying air

Abstract

The invention provides a heat-insulation and heat-preservation water-based coating material with an air purifying function. The water-based coating material is prepared through compounding raw materials, such as diatomite, hollow glass beads, lignocellulose, zirconium phosphate loaded sliver powder, nano zinc oxide, tourmaline powder, aluminum oxide, hydroxypropyl methylcellulose, a pure acrylic emulsion, a dispersing agent 5040, 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate, 1,2-propanediol, Kathon, a silicone defoamer, deionized water and the like. The water-based coating material provided by the invention further has the functions of improving air quality, regulating air humidity, preventing mildew and the like through adsorbing harmful substances in air and releasing negative ions, besides an excellent heat insulation function.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a heat-insulating water-based paint with the function of purifying air. Background technique [0002] Energy-saving buildings are an effective way to improve the efficiency of building energy use. The methods used for building material insulation and energy conservation are generally the use of energy-saving insulation materials or coating insulation coatings on the exterior and / or interior walls of buildings. However, in our country, most of the energy-saving insulation materials used are organic substances, such as polystyrene foam, polyurethane foam, etc., and these materials have extremely poor fire resistance, are easy to melt, and even produce toxic gases when they catch fire. [0003] In the existing thermal insulation coatings, many organic solvents are used as solvents, which will cause serious indoor air pollution and bring hidden dangers to people's health. Although ...

However, in our country, most of the energy-saving insulation materials used are organic substances, such as polystyrene foam, polyurethane foam, etc., and these materials have extremely poor fire resistance, are easy to melt, and even produce toxic gases when they catch fire.

[0003] In the existing thermal insulation coatings, many organic solvents are used as solvents, which will cause serious indoor air pollution and bring hidden dangers to people's health

Although there are also some water-based thermal insulation coatings, the functions of these coatings are relatively single.
