Abstract

The invention discloses a preparation method of high-performance window film insulation medium. The preparation method includes: firstly, selecting blue WO3, ATO and ITO nano-powders according to corresponding conditions, using a planet wet ball-milling disperser and a scientific and reasonable combining-scattering comparison method, and optimally selecting factors such as selection proportion and solid content of different insulation media, selection on mill ball size, control on rotation speed and continuous dispersion time. Therefore, optimal transmittance of visible light, optimal insulation, optimal ultraviolet proofing and optimal performance of high-performance insulation medium are achieved. The high-performance window film insulation medium prepared by the preparation method is high in transparency, thermal insulation and ultraviolet proofing, has high insulation in the near-infrared area of 780nm-900nm, is widely applied to production of high-performance insulation glass and high-performance insulation window films, and has very important social and economic values.

Description

technical field [0001] The invention relates to a preparation method of a high-performance window film heat insulation medium. Background technique [0002] At present, the window film heat insulation medium produced at home and abroad mainly adopts nano-powder and nano-slurry such as single component ATO or ITO or other nano-ceramic microbeads, but when these nano-materials are only used alone, these single heat-insulating There are always many defects in the optical performance index of the medium. The single-component W03, ATO, and ITO nanomaterials have their own advantages and disadvantages. Their respective characteristics are that the rejection ratio of ATO to IR is higher than ITO nanomaterials are good, ATO has the best IR rejection rate near 1100nm, WO3 has better IR rejection rate than ATO and ITO nanomaterials at wavelengths around 780nm-1000nm, and WO3 has the best IR rejection rate near 900nm. However, the transmittance of ITO in the visible light region with ...
