Problems solved by technology

Among them, although ATO and ITO have high visible light transmittance, they can only shield infrared rays with a wavelength band greater than 1500nm, and their prices are expensive and the preparation process is complicated.
Lanthanum hexaboride can only shield the 750-1300nm band in the infrared region, and the particle size is too small to be easily oxidized, thereby inhibiting its surface localized plasmon resonance effect and reducing its absorption capacity
However, the nanomaterials of this technology only provide the heat insulation effect of the coating, and the hydrophobic effect of the coating is only provided by polysilazane. The shape of the nano heat insulation material cannot provide the coating with a certain roughness to achieve super Hydrophobic effect, so the coating only has hydrophobic effect and cannot achieve super-hydrophobic effect

Abstract

The invention discloses a tungsten bronze-based super-hydrophobic transparent heat-insulating coating and a preparation method thereof. The tungsten bronze-based super-hydrophobic transparent heat-insulating coating is obtained by adding hydrophobically modified nano tungsten bronze and hydrophobically modified powder into a resin solution for dissolving an organic solvent to form a film, synthesizing nanometer cesium-tungsten bronze and nanometer sodium-tungsten bronze through a solvothermal method, then respectively modifying the nanometer cesium-tungsten bronze, the nanometer sodium-tungsten bronze and nanometer silicon dioxide to serve as inorganic components, combining organic resin to prepare the super-hydrophobic coating, and coating the surface of a substrate with the tungsten bronze-based super-hydrophobic transparent heat-insulating super-hydrophobic coating by adopting a film forming process, wherein the static contact angle of the obtained tungsten bronze-based super-hydrophobic transparent heat-insulating coating is larger than 155 degrees, and the rolling angle is smaller than 10 degrees. The nano tungsten bronze-based super-hydrophobic transparent heat-insulating super-hydrophobic coating is good in dispersity, and a prepared coating is good in binding force with a matrix and good in transparent heat-insulating effect.

Description

technical field [0001] The invention relates to a transparent heat-insulating coating, in particular to a tungsten bronze-based superhydrophobic transparent heat-insulating coating and a preparation method thereof. The coating is mainly used for building exterior walls, glass, etc., and belongs to the technical field of superhydrophobic coating prepared by organic-inorganic composite method . Background technique [0002] In recent years, with the rapid development of social economy, people's demand and consumption of energy are increasing day by day. At the same time, energy consumption has also brought about many serious environmental problems. Therefore, energy and environmental problems have become two major factors restricting the development of human society. In order to solve the energy crisis, on the one hand, it is necessary to continuously develop new clean energy sources, and on the other hand, it is to improve energy utilization and reduce energy waste, which is ...
