Important component of crack-resistant insulated flame-retardant building material coating

Abstract

The invention discloses an important component of a crack-resistant insulated flame-retardant building material coating. The important component is characterized in that nanosilicon dioxide and a graphene microchip are added to an insulated flame-retardant coating, wherein the nanosilicon dioxide accounts for 1%-5% of the weight of basic components of the insulated flame-retardant coating; the graphene microchip accounts for 0.5%-5% of the weight of the basic components; the crack resistance of the coating is improved by adding two inorganic non-metallic materials, namely the nanosilicon dioxide and the graphene microchip; crystal is grown and generated from the graphene microchip in a three-dimensional cellular way (same as a diamond mine); four valence electrons of each carbon atom form covalent bonds to be bound, cannot form electron flow in directional movement, and cannot conduct electricity; generated graphite carbon crystal is ground in a single direction in a wet nano-grinding manner, so as to generate the graphene microchip of which the thickness is in a nanometer scale and the area is in a micron scale; due to the addition of the graphene microchip into the coating, the fusion performance of the coating can be greatly improved; and the coating has good crack resistance.

Description

technical field [0001] The invention relates to the technical field of inorganic non-metallic materials, in particular to an important component of an anti-crack, heat-retaining, flame-retardant building material coating. Background technique [0002] After the 1970s, the world's climate became warmer, and the earth's energy sources were increasingly exhausted. In my country's energy consumption, building energy consumption accounts for 30-40% of human energy consumption. Improving the thermal insulation performance of buildings is an important way to save energy and improve the function of buildings. Applying thermal insulation coatings to the surface of buildings can effectively reduce the temperature on the surface and inside of buildings. In recent years, with the popularization of building energy conservation, thermal insulation coatings have attracted more and more attention due to their advantages of economy, convenience and good thermal insulation effect. Therefore...

Problems solved by technology

In order to meet the basic physical and chemical performance requirements of ordinary exterior wall coatings, this type of existing traditional thermal insulation coatings must ensure a relatively high addition of organic polymer emulsions in the coatings, resulting in unsatisfactory thermal insulation effects

And it does not have anti-crack performance, so it has received many restrictions in use
