Cesium tungsten bronze-based self-cleaning nano heat-insulation coating material and preparation method thereof

Abstract

The present disclosure provides a cesium tungsten bronze-based self-cleaning nano heat-insulation coating material, and method of preparing the same. Cesium tungsten bronze nanoparticles are prepared by hydrothermal method using WCl.sub.6 and CsOH.5H.sub.2O as raw materials, PVP as a surfactant and acetic acid as an acid catalyst. TiO.sub.2 nanoparticles are prepared from TiCl.sub.4. Subsequently ball milling and dispersing of the cesium tungsten bronze nanoparticles, the TiO.sub.2 nanoparticles, and a silane coupling agent with water to obtain an aqueous slurry containing cesium tungsten bronze/TiO.sub.2 composite particles is performed. The concentration of the aqueous slurry containing cesium tungsten bronze/TiO.sub.2 composite particles is adjusted to obtain a self-cleaning nano heat-insulation coating material.
