摘要
研究了环氧类基层处理剂、聚乙烯醇类基层处理剂、丙烯酸酯类基层处理剂分别对不同防水涂料在混凝土基层上粘结性能的影响;以及两种不同防水涂料复合使用时粘结性能的差异。结果表明:基层处理剂的使用均会提高防水涂料与基层的粘结强度;两种防水涂料复合使用时,体系的粘结强度高于与基层粘结强度低的防水涂料,低于与基层粘结强度高的防水涂料;两种防水涂料复合使用时,与基层粘结强度高的防水涂料打底的体系粘结强度更高。
The effects of epoxy substrate treatment agent,polyvinyl alcohol substrate treatment agent and acrylic substrate treatment agent on the bonding strength of different waterproofing coatings on concrete substrate are studied in this article.It also studied the difference in bonding strength when two different waterproofing coatings used in combination.The results indicate that the use of substrate treatment agents can improve the bonding strength between waterproofing coatings and the substrates.In the case of two types of waterproofing coatings are used in combination,the bonding strength of the combined system is higher than that of the waterproofing coating with low bonding strength to the substrates,but lower than that of the waterproofing coating with high bonding strength to the substrates.When two types of waterproofing coatings are used in combination,and the waterproofing coating with high bonding strength to the substrate is placed in the bottom layer,the system has a higher bonding strength.
