摘　　要：对不同类型外墙腻子、外墙涂料分别在不同环境作用下进行粘结强度、柔韧性以及拉伸强度、附着力试验,探讨复杂环境作用下饰面材料的长期服役行为,研究不同环境作用下饰面材料耐久性的演变。试验结果表明,温湿度、酸雨、光照等均会影响外墙腻子、外墙涂料的使用性能,其中以酸雨对外墙腻子、外墙涂料的影响最大。因此在酸雨严重区域,应该选择耐酸性优异的饰面材料。Carry out tests on bonding strength,flexibility,tensile strength,and adhesion of different types of exterior wall putty and exterior wall coating under different environments,explore the long-term service behavior of covering materials under complex environments,and study the evolution of the durability of coatings under the action of different environments.The test results show that temperature and humidity,acid rain,and light can affect the performance of exterior wall putty and exterior wall coatings.Among them,acid rain has the greatest impact on exterior wall putty and exterior wall coatings.So in areas with severe acid rain,decorative material with excellent acid resistance should be selected.
