摘　　要：对JS防水涂料吸水率的影响因素进行了试验研究,结果表明:相对于VAE乳液和苯丙乳液,丁苯乳液制得的JS防水涂料吸水率更低,并且乳液含量越高,吸水率越低;随着水泥添加量的增加,JS防水涂料的吸水率先降低后升高;浸水时间延长,吸水率的涨幅呈先平稳后显著下降的趋势;钛酸酯偶联剂比硅烷偶联剂更有助于降低JS防水涂料的吸水率;沸石粉的添加有助于降低JS防水涂料的吸水率,提高耐水性。The factors influencing the water absorption of JS waterproofing coating are studied in this article.The results show that compared with VAE and styrene acrylic emulsion,the water absorption of JS waterproofing coating made of styrene butadiene emulsion is lower,and the higher the content of emulsion,the lower the water absorption will be;with the increase of cement addition,the water absorption of JS waterproofing coating first decreases and then increases;the increase amount of water absorption rate shows a trend of first stabilizing and then significantly decreasing as the soaking time prolongs;titanate coupling agents are more helpful in reducing the water absorption of JS waterproofing coatings than silane coupling agents;the addition of zeolite powder helps to reduce the water absorption of JS waterproofing coatings and improve their water resistance.
