弹性体改性沥青耐根穿刺防水卷材是以聚酯纤维毡为胎基，以添加化学阻根剂的弹性体改性沥青为涂盖材料，以聚乙烯膜为隔离材料制成的改性沥青防水卷材，具有优异的防水性能，且能长久保持防水效果，在种植屋面应用时，能够承受植物根系穿刺，还不影响植物生长，广泛应用于地下、屋面等工程部位。
JGJ155-2013《种植屋面工程技术规程》中规定：种植屋面防水层应满足一级防水等级设防要求且种植屋面防水层应采用不少于两道防水设防，上道应为耐根穿刺防水材料，即耐根穿刺防水材料设置在普通防水层上面，但是在实际应用时，随着使用时间的延长，弹性体改性沥青耐根穿刺防水卷材中的油分迁移，影响防水质量，因此，急需改善弹性体改性沥青耐根穿刺防水卷材的渗油性。

S2、在175℃下，将浸涂后的聚酯胎基层用涂盖料进行涂覆，在聚酯胎基层的上下表面均形成弹性体改性沥青层；
S3、在涂覆后的聚酯胎基层的上下表面即弹性体改性沥青层的表面再覆盖聚乙烯膜，得到聚乙烯膜层，冷却、定型，得到高耐久性耐穿刺高分子防水卷材。
对比例1
与实施例1的区别仅在于预浸料中将二羟基聚二甲基硅氧烷替换为聚二甲基硅氧烷。
对比例2
与实施例1的区别仅在于预浸料中未加入二羟基聚二甲基硅氧烷。
对比例3
与实施例1的区别仅在于涂盖料中未加入聚乙烯吡咯烷酮。
对实施例1-8及对比例1-3得到的高耐久性耐穿刺高分子防水卷材进行如下性能测试：
(1)渗油性：按照GB/T18242-2008《弹性体改性沥青防水卷材》中规定的方法进行测试
(2)人工气候加速老化：按照GB/T18244-2000《建筑防水材料老化试验方法》中规定的方法进行测试；
测试结果见下表：
表1 实施例1-8及对比例1-3的防水卷材测试结果

从上表中数据可以看出，实施例1-8的防水卷材的渗油性张数均≤1张，且人工气候加速老化后的拉力保持率(横向和纵向)均≥91％，符合GB/T35468-2017《种植屋面用耐根穿刺防水卷材》的要求。
实施例1与实施例3-8对比，实施例3的防水卷材的耐老化性能更好，说明特定质量比的10#沥青和200#沥青与90#沥青协同，能提高防水卷材的耐老化性能。
实施例1与对比例1-3相比，渗油性张数更少，且人工气候加速老化后的拉力保持率更高，说明本发明中，通过在弹性体改性沥青层的浸涂料中加入二羟基聚二甲基硅氧烷，涂盖料中加入聚乙烯吡咯烷酮，不仅有效阻止了弹性体改性沥青层中油分的迁移，提高了防水卷材的抗渗油性，还显著提高了防水卷材的耐老化性。
将实施例1的防水卷材送至北京市园林科学研究院进行耐根穿刺性能检测：
检测结果为：整个试验期间试验箱中植物的生长量达到对照箱植物平均生长量的80％(高度、干茎直径)、且每个试验箱中都没有任何根穿刺现象发生。
检测结论为：送检的弹性体改性沥青耐根穿刺防水卷材(样品编号：2019B013)的耐根穿刺性能符合《种植屋面用耐根穿刺防水卷材》(GB/T35468-2017)的规定。
将实施例1的防水卷材送至国家建筑材料工业建筑围护材料及管道产品质量监督检验测试中心，检测项目为：厚度、耐霉菌厚度，耐霉菌腐蚀性，接缝剥离强度，面积，单位面积质量，厚度，外观，可溶物含量，耐热性，低温柔性，不透水性，最大峰拉力，最大峰时延伸率，浸水后质量增加，热老化，渗油性，接缝剥离强度，卷材下表面沥青涂盖层厚度，人 工气候加速老化，检测结论为：该样品经检测，所检项目符合GB/T35468-2017《种植屋面用耐根穿刺防水卷材》中指标要求。
以上仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
