Study on Preparation of SnO_2 Resin Thermal Insulation Film With Liquid Phase Precipitation Process

当今世界以节能减排为主题的低碳经济发展潮流中,包括汽车玻璃和建筑玻璃的隔热贴膜节能技术受到了越来越多的关注.本文采用液相沉积法制备纳米二氧化锡聚丙烯酸酯隔热有机膜.首先选择有利于产生异相沉积的前驱体溶液浓度及pH值,配制浓度为2mM^10mM的低浓度四氯化锡溶液,盐酸浓度选择0.1M^0.4M;选取甲基丙稀酸甲酯34.5%~90%、丙烯酸丁酯10%~35.5%、甲基丙稀酸0~30%、偶氮二异丁腈0.1%~0.3%,制备聚丙烯酸酯薄膜;将制得的聚丙烯酸酯薄膜放入氯化锡溶液中,控制反应温度为40℃~80℃,反应时间为6h^18h,将薄膜拿出,洗涤、干燥得纳米氧化锡有机隔热薄膜.通过XRD分析及SEM观察,氧化锡均匀沉积在有机薄膜表面,具有较好的隔热性能.

In the modem world, the theme of low carbon economic development trend advocates energy conservation and discharge reduction, and the energy - saving technology of thermal insulation film of automobile glass and construction glass has attracted increasing more attention. This paper adopts liquid phase precipitation process to pre- pare nano SnO2 polyacrylate thermal insulation organic film： first, select precursor solution concentration in favor of generating outphase precipitation and pH value to prepare SnCl4 solution with low concentration 2mM - 10mM, and hydrochloric acid with concentration 0. 1M -0. 4M; select methyl methacrylate 34.5% -90%, BA 10% -35.5%, MAA 0% -30% and AIBN 0.1% -0.3% to prepare polyacrylate film; put the prepared PA film in SnCl solution, control reaction temperature to be 40℃ - 80℃, maintain reaction time 6 - 18h, take out the film, wash and dry to get nano SnO2 organic thermal insulation film. According to XRD analysis and SEM observation, SnO2 is uniformly deposited on the surface of organic film, having good thermal insulation performance.
