摘要
制备了高强度聚氨酯防水涂料,并尝试将其应用于种植屋面的阻根防水层;同时设计并进行了耐根穿刺快速植物试验,研究了化学阻根剂对涂膜力学性能和阻根性能的影响。结果表明:本研究制得的聚氨酯防水涂料综合性能满足标准要求;耐根穿刺快速植物试验中,添加阻根剂后涂膜具有一定的阻根效果但其拉伸性能有所降低。
A high strength polyurethane waterproofing coating is prepared for the purpose of trying to use it in root-resistant waterproofing layer of planted roof.For this reason,a fast root-resistant plant experiment is designed and conducted in which influences of chemical root-resistant agent on mechanical properties and root resistance of the coating membrane are studied. The results show comprehensive performance of the polyurethane waterproofing coating can be up to standard.In the fast plant experiment,coating membrane added with root-resistant agent has certain positive root-resistant effect but its tensile strength has somewhat reduced.
