Description

一种硅烷改性聚四氟乙烯防水薄膜及其制备方法
技术领域
本发明涉及防水薄膜技术领域，尤其涉及一种硅烷改性聚四氟乙烯防水薄膜及其制备方法。
背景技术
聚四氟乙烯防薄膜是一种使用了氟取代聚乙烯中所有氢原子的人工合成高分子材料。这种材料具有抗酸抗碱、抗各种有机溶剂的特点，几乎不溶于所有的溶剂。同时，防水透气膜具有耐高温的特点，它的摩擦系数极低，所以可作润滑作用之余，亦成为了易洁镬和水管内层的理想涂料；
防水透气膜在很多行业应用非常广泛：现代社会汽车运用普遍，运输过程中会遇到不同的天气和路况。车灯始终暴露于外部环境中，尘雾、雨雪、路面碎物及泥污都会影响车灯的照明，从而影响车辆的行驶过程的安全度。外部温度的骤降会导致内部压力的下降，使设备容易吸入污染物与增加结雾，最终造成车灯故障。防水透气膜可以给车灯提供持久防护，免受外部水汽、灰尘、油污及其他污物的侵入。同时产品独特的透气功能随着压力的变化进行气体互换，从而减小密封件上的压力，延长产品的使用寿命。在传感器设备方面：防水透气产品可以有效抵御温度变化导致的压差所产生的不利影响。使用防水透气膜能在环境温度和压力变化时迅速平衡壳体内外压力，在气体传感器和电化学传感器中，防水透气产品可防止灰尘、污垢或液体侵入传感头。同时，防水透气膜可让气体立即通过薄膜，从而确保传感器响应速度保持恒定，防止测量结果出现错误和延迟。在户外通信设备方面：户外通信设备安装了防水透气膜产品后，由于温度变化而造成的压差将不再对设备壳体构成负面影响，因为防水透气产品能在环境温度和压力变化时迅速平衡壳体内外压力；
然而传统防水透气膜功能性比较单一，且有的加入了有毒的增塑剂等原料，环保性差，透气膜的使用范围较小，有的抗冲击强度低，容易损坏，有的耐老化性差，使用寿命短，因此，研究更高性能的防水薄膜就显得尤为必要。
