Problems solved by technology

[0007] The present invention aims at the problem that the heat insulation effect of the existing ceramic heat insulation film is significantly reduced when the heat absorption reaches the saturation value due to the heat insulation realized by spectral selective absorption, the heat insulation film is easy to age, or the preparation process is complicated. It integrates spectral selective absorption and selective reflection. While ensuring high transmission of visible light, it can also absorb and reflect near-infrared rays well, effectively solving the problem when the heat absorbed by the ceramic heat insulation film reaches a certain saturation value. Spectrum-selective nano-heat-insulating PVB film for the problem of significant decline in heat-insulating effect, and a preparation method for the spectral-selective nano-heat-insulation PVB film

Abstract

The invention relates to the technical field of heat-insulating energy-saving materials, in particular to a spectral selectivity nano heat-insulating PVB (polyvinyl butyral) film and a preparation method thereof. The preparation method includes that through synergistic effect of near infrared long-wave barrier nano material dispersion liquid, near infrared short-wave barrier nano material dispersion liquid and infrared reflection nano material dispersion liquid, the PVB film integrates spectral selectivity absorption and spectral selectivity reflection, so that high transmittance of visible light is guaranteed, near infrared rays can be well absorbed and reflected, the problem of remarkable lowering of heat-insulating effect of a ceramic heat-insulating film due to the fact that heat absorbed by the ceramic heat-insulating film reaches a saturation value is solved effectively, and the problems of quick aging and interlayer glass delaminating of the PVB film caused by overhigh temperature are solved.Proper amounts of metal oxide, hexaboride and metal silver are added into a raw material, and plasma resonance absorption and Bragg reflection are introduced to the surface of the material, so that high performance of the heat-insulating PVB film is realized and barrier rate of 800-2500 nm in wavelength is high.

Description

technical field [0001] The invention relates to the technical field of heat insulation and energy saving materials, in particular to a spectrally selective nano heat insulation PVB film and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of my country's real estate and real estate industry, glass curtain walls have been widely used in large buildings, but the safety hazards brought about by it are also increasing. In recent years, the problem of glass self-explosion has been frequently seen in media reports, especially the incident of glass rain hurting people caused by the warehouse explosion in Tianjin Binhai New Area in 2015, which made the city full of high-rise buildings suddenly become dangerous, and skyscrapers, which are regarded as symbols of modern cities, have become citizens’ nightmares root. Therefore, the safety of curtain wall glass has aroused great concern from the society and the leaders of the Minist...
