一种新型环保耐根穿刺防水卷材
一、技术领域
本发明涉及一种新型环保耐根穿刺防水卷材，具有防水、阻止植物根穿透、环保、防腐、防霉的建筑类防水材料，它是有关建筑防水工程用防水材料。
二、背景技术
一种新型环保耐根穿刺防水卷材于传统防水卷材以及普通高分子防水材料、各类防水涂料都无法满足建筑种植系统的要求，因为这些材料不具有抗根性能，很容易被植物根尖穿透，造成建筑体破坏和渗漏，直接导致“建筑种植绿化”体系的失败。而一种聚氯乙烯双面复合耐根穿刺防水卷材以特殊SBS混合料配方为阻根防水层，具有长期的耐植物根(或根状茎)穿刺性能、粘结力强、稳定性好、低温柔性和耐热性好、耐化学腐蚀及抗辐射能力强，20多年来仍然表现出很好的阻根防水性能，以纳米光触媒TiO2为添加剂纳米光触媒是指在光照下，自身不发生化学变化，却可以促进化学反应的物质，其功能就象光合作用中的叶绿素。锐钛型纳米TiO2是最主要的光触媒材料，当其吸收太阳光或其他光源中的能量后，粒子表面的电子被激活，逸离原来的轨道，同时表面生成带正电的空穴。逸出的电子具有强还原性，空穴则具有强氧化性，两者与空气中的水气反应后会生成活性氧和氢氧自由基。活性氧、氢氧自由基能将大部分有机物、污染物、臭气、细菌等氧化分解成无害的二氧化碳和水。在所有的光触媒材料中，纳米TiO2不仅具有很高的光催化活性，且具有耐酸碱腐蚀、耐化学腐蚀、无毒等优点，价格也适中，具有较高的性价比，因而市场上大多使用纳米二氧化钛作为主要原材料。一种新型环保耐根穿刺防水卷材具有防水、阻止植物根穿透、环保、防腐、防霉等优点，是防水材料中不可多得的佳品。
