Description

一种改性沥青柔性防水卷材
技术领域
本发明涉及一种防水卷材，具体来说，涉及一种改性沥青柔性防水卷材，属于防水材料领域。
背景技术
预浸料是用树脂基体在严格控制的条件下浸渍连续纤维或织物，制成树脂基体与增强体的组合物，是制造复合材料的中间材料。预浸料中树脂状态与化学性质应符合产品对象的特定要求,诸如聚合或缩聚程度、分子量及其分布、凝胶时间以及加压段区域等。预浸料对卷材的性能影响巨大。
传统的沥青防水卷材，用原纸、纤维毡等胎体材料浸涂沥青，表面撒布粉状、粒状或片状材料，制成可卷曲的片状防水材料。防水卷材要求有良好的耐水性，对温度变化的稳定性(高温下不流淌、不起泡、不淆动;低温下不脆裂)，一定的机械强度、延伸性和抗断裂性，要有一定的柔韧性和抗老化性等。
沥青防水卷材分为有胎卷材和无胎卷材。凡是用厚纸或玻璃丝布、石棉布、棉麻织品等胎料浸渍石油沥青制成的卷状材料，称为有胎卷材。将石棉、橡胶粉等掺入沥青材料中，经碾压制成的卷状材料称为辊压卷材即无胎卷材。
