Inorganic multifunctional paint taking potassium silicate as film-forming substance, and preparation method thereof

Abstract

The invention discloses an inorganic multifunctional paint taking potassium silicate as the film-forming substance, and a preparation method thereof. The paint is composed of nano TiO2, tourmaline powder, meerschaum, laubanite, China hemp fiber powder, diatomite, titanium dioxide, talcum powder, calcium ash powder, calcium carbonate, kaolin, cellulose ether, and potassium silicate. The inorganic multifunctional paint taking potassium silicate as the film-forming substance does not contain any chemical auxiliary agent, which exists in the conventional emulsion paint; moreover, takes inorganic potassium silicate as the film-forming substance, thus does not contain any organic compound, saves the chemical raw materials used in the conventional emulsion paint, avoids to generate the volatile organic compounds (VOC), which pollutes the environment, at the same time; integrates the functions of low carbon, saving energy, decomposing formaldehyde, purifying the air, releasing the negative ions, modulating the air humidity, preventing fire, insulating the sound, killing the bacteria, and the like; and can be widely applied to the decoration of outer walls of buildings.

Description

technical field [0001] The invention belongs to the technical field of architectural coatings, more specifically, the invention relates to an inorganic multifunctional coating using potassium silicate as a film-forming substance and a preparation method thereof. Background technique [0002] Last year, more than 4,000 newly renovated houses monitored in various parts of my country had an air quality pass rate of less than 20%. The main reason is that harmful pollutants such as furniture, building decoration materials, and wall materials seriously exceed the standard. People spend 76% of their time indoors, and the quality of indoor air is directly related to the physical health of the human body. From the perspective of air purification, interior decoration materials must not only purify the pollution caused by interior decoration, but more importantly, have the ability to purify the pollution caused by the body's own metabolism, and require materials to have healthy and co...

Problems solved by technology

Yet the latex powder in all researches at present is all organic substances, as the patent application number is 200910193352, and the polymer latex powder used in the patent name "building dry powder coating and its preparation method and using method" is a kind of redispersible Polymer powder, polymer powder can be the redispersible latex powder that forms after drying the acrylic polymer emulsion formed by the copolymerization of various acrylate monomers and methacrylate monomers, etc., therefore, inevitably still produce The problem with VOCs

[0007] In short, judging from the actual situation at home and abroad, no real zero-VOC architectural coatings have been reported yet
