摘　　要：论文测试了3种硅基防水涂料的力学性能,并通过一系列的微观测试方法研究了3种硅基防水涂料的主要成膜物、颜填料的种类及含量,并将微观测试的结果与力学性能的结果相互印证。利用在较高温度下热处理的硅基防水涂料的力学性能和其他性能分析的结果,评价了3种硅基防水涂料的耐候性,并找出了一款易变黄的硅基防水涂料,分析了其黄变的可能原因。In this paper,the mechanical properties of three silicone waterproof coatings were tested,and the types and contents of main film-forming substances,pigments and fillers of the three silicone waterproof coatings were studied by a series of microscopic test methods,and the results of microscopic test and mechanical properties were mutually confirmed.Based on the results of mechanical properties and other performance analysis of silicone waterproof coatings after heat treatment at higher temperature,the weather resistance of three silicone waterproof coatings was evaluated.A silicone waterproof coating,which was easy to yellowing,was found,and the possible causes of its yellowing were analyzed.

关 键 词：硅基防水涂料 有机硅弹性防水涂料 力学性能 热处理 黄变
