SR屋面防水涂料是一种水溶性材料,它是以废橡胶为基础材料,加入一定量的沥青,经水乳而成的。我们使用该涂料多年,经观察发现个别部位有渗水现象,经采取改进措施后,取得了较好效果。一、渗漏原因 1.积水问题当屋面找平层局部低凹或排水天沟坡度不够时,就会形成积水。据资料介绍,雨水对水溶性防水涂料有“再乳化性”作用。涂膜浸水时间过长,虽然肉眼看不出明显的再乳化现象,但它能使涂膜的原有结构变松,
SR roof waterproofing coating is a water-soluble material. It is based on waste rubber and is made by adding a certain amount of bitumen to water. We have used this paint for many years and found that there was water seepage in individual parts after observation. After taking improvement measures, we achieved better results. First, the cause of leakage 1. Water problems When the local leveling layer depression or drainage gutter slope is not enough, it will form water. According to information, rain has a “re-emulsification” effect on water-soluble waterproof coatings. When the film is soaked in water for a long time, although the visible re-emulsification phenomenon is not visible to the naked eye, it can make the original structure of the film loose.
