Silicon dioxide aerogel heat-preservation and heat-insulation composite film and preparation process thereof
The invention discloses a silicon dioxide aerogel heat-preservation and heat-insulation composite film and a preparation technology thereof, and particularly relates to the technical field of aerogel composite film preparation. The silicon dioxide aerogel heat-preservation and heat-insulation composite film comprises a silicon dioxide aerogel layer and two TPU base-material-free high-temperature hot melt adhesives, the two TPU base-material-free high-temperature hot melt adhesives are arranged at the top and the bottom of the silicon dioxide aerogel layer respectively, the silicon dioxide aerogel layer is prepared by foaming and shaping amorphous silicon dioxide, polyurethane, oxidation modified carbon black, silicon carbide and zirconium oxide. According to the invention, a surface powder is firmer through a hot pressing temperature machine and a calender, and then the hot pressing temperature machine and the calender are used for compounding and processing the silicon dioxide aerogel heat-preservation and heat-insulation material from which the powder falls and the high-temperature-resistant TPU base-material-free high-temperature hot melt adhesive into the non-falling powder composite material, so that the purpose that no powder overflows and falls on the surface of the material is achieved; and the mixed powder of modified oxidized carbon black, silicon carbide and zirconium oxide is added under different foaming temperature conditions, so that the shading property of the composite material can be effectively improved, and the heat insulation property of the composite material under a high-temperature condition can be further improved.
本发明公开了一种二氧化硅气凝胶保温隔热复合膜及其制备工艺，具体涉及气凝胶复合膜制备技术领域，包括二氧化硅气凝胶层和两个TPU无基材高温热熔胶，两个所述TPU无基材高温热熔胶分别设在二氧化硅气凝胶层的顶部和底部，所述二氧化硅气凝胶层由无定形二氧化硅、聚氨酯、氧化改性炭黑、碳化硅和氧化锆发泡定型制成。本发明通过热压温度机与压延机使表面粉体更加紧固，在使用热压温度机与压延机使脱落粉体的二氧化硅气凝胶保温隔热材与耐高温TPU无基材高温热熔胶复合加工成不脱落粉体复合材料，已达到材料表面没有任何粉体溢出、脱落的目的，并在不同的发泡温度条件下加入改性氧化炭黑、碳化硅和氧化锆的混合粉末能够有效的提高复合材料的遮光性，进而能够提高本发明在高温条件下的隔热性能。
