Graphene-modified nano thermal insulating slurry and preparation method thereof

Abstract

The invention discloses graphene-modified nano thermal insulating slurry and preparation method thereof. The graphene-modified nano thermal insulating slurry is prepared from the following components in parts by weight: 5 to 15 parts of nano ATO powder; 10 to 20 parts of graphene aqueous dispersion; 1 to 5 parts of dispersing agent; 50 to 80 parts of deionized water; and 1 to 3 parts of defoaming agent. The nano ATO powder with a thermal insulating function is modified by graphene, so that the prepared thermal insulating slurry has a thermal insulating function when being used in building glass (or other base materials), and also has high visible light transmittance in the scope of visible light, high infrared ray blocking rate, high adhesive force and high hardness. In addition, the preparation method provided by the invention is simple, the equipment investment is less, the cost is low and environmental protection is realized; and the slurry is extremely stable, can be stored at least for six months at normal temperature, and can be widely used as a thermal insulating agent, an antistatic agent and the like of a glass window.

Description

technical field [0001] The invention relates to the field of thermal insulation slurry, in particular to a graphene-modified nano thermal insulation slurry and a preparation method thereof. Background technique [0002] Building thermal insulation is an important aspect of saving energy and improving the living and use functions of buildings. Building energy consumption generally accounts for 30% to 40% of the total energy consumption of human beings, and most of them are heating and air-conditioning energy consumption, so building energy conservation is of great significance. According to research statistics, in terms of building energy consumption, the heat dissipation of building doors and windows in my country accounts for more than 50% of the total heat dissipation of the building periphery, which is 3 to 5 times that of developed countries. Therefore, improving the thermal insulation performance of doors and windows is an effective way to reduce building energy consum...
