为开发对太阳光具有良好隔热效果的涂层织物,在聚偏氟乙烯树脂(PvDF)溶液中添加对太阳光具有反射作用的二氧化钛、氧化锌粒子制备功能涂层液,并对玻璃纤维织物进行涂装,制备出具有良好的太阳光热反射功能的涂层织物。探索了二氧化钛、氧化锌粒子的组成和用量以及涂层工艺对涂层织物的隔热影响。结果表明,涂层液的较优配方为:w(PVDF)=15%,w(TiO2)=15%,w(ZnO)=5%,W(DMF)=65%;最佳涂层工艺为:玻璃纤维织物表面PVDF打底层的厚度为0.5mm,功能涂层厚度为0.25mm。热性能测试仪测试表明,涂层织物对光射线具有显著的隔热性能,氧指数法测试说明涂层织物为不燃织物;涂层织物属于A级抗静电织物,此外还具有一定的自清洁性能。
In order to develop the solar-reflective heat-insulating coating fabric, some inorganic particles such as TiO2 and ZnO, which can effectively reflect the solar ray, have been added into the PVDF solution to obtain the coating solution firstly. Then, the coating solution was used to coat on the glass fiber fabrics. Effects of the TiO2 and ZnO usages and coating thickness on the heat resistant properties of fabric have been investigated. Results showed the optimum coating liquid formulation: w(PVDF)=15%, w(TiO2)=15%, w(ZnO) = 5%, w(DMF)=65% and the optimum coating process is as follows: the thickness of PVDF layer on glass fabric surfaces is 0.5 mm, the thickness of the functional coating layer is 0.25 mm. Thermal performance test showed that the coating fabrics have significant thermal insulation properties. Oxygen index test showed the coated fabric is a non-combustible material. Furthermore, the coated fabric belongs to class A antistatic fabric and has a certain self-cleaning property.
