Abstract

The invention discloses a method for preparing nanoscale graphene doped tin antimony oxide (ATO) thermal insulation dispersion liquid. ATO is prepared through combustion of an ethylenediaminetetraacetic acid-citric acid (EDTA-CA) bi-functional chelating agent, then nanoscale graphene and nanoscale ATO are added to a proper amount of N-methyl pyrrolidone (NMP), particle aggregation is inhibited through PH value regulation, and stirring is conducted to enable graphene and ATO to be quickly dispersed in NMP respectively; the two kinds of NMP dispersion liquid are mixed, PH value is regulated again, ultrasonic treatment and ball milling are conducted to enable graphene, ATO and solvent to be mixed quickly and fully, high dispersibility and high stability on the micro-scale level are realized, and the obtained nanoscale graphene doped ATO material can be used for manufacturing high-thermal-conductivity thermal insulation paint.

Description

technical field [0001] The invention relates to a preparation method of a nanoscale graphene-doped antimony tin oxide (ATO) heat-insulating coating. In particular, it relates to a method for preparing ATO by a combustion method and mixing graphene into ATO to make a coating. Background technique [0002] In today's society, with the advancement of technology and the continuous improvement of living standards, people pay more and more attention to energy conservation and environmental protection issues, and put forward more requirements for energy conservation and environmental protection. At present, large-scale glass windows and glass curtain walls are widely used in buildings. Although they are beautiful and light-transmitting, the energy consumption of cooling in summer and heating in winter also increases due to poor thermal insulation of glass, which is not conducive to energy conservation and environmental protection. In order to reduce energy consumption, the researc...
