摘　　要：分别参照国标GB/T 13477.19—2017《建筑密封材料试验方法第19部分:质量与体积变化的测定》规定的金属环法和企业简易铝箔纸法对市场上40种建筑用硅酮耐候密封胶进行质量损失率测试,对两种方法试验结果进行了比对分析,探讨两种测试方法间数据的关联性以及铝箔纸法替代金属环法的可行性。The mass loss rate of 40 kinds of silicone weather resistant building sealants on the market is tested by referring to the metal ring method specified in the national standard GB/T 13477.19—2017“Test method for building sealants part 19:determination of change in mass and volume”and the simple aluminum foil method used by enterprises.The test results of the two methods are compared and analyzed,the correlation between the data of the two test methods,and the feasibility of the replacement of the metal ring method with aluminum foil method are discussed.
