摘　　要：介绍了国内建筑用硅酮密封胶标准现状,分析了滥用劣质增塑剂对幕墙质量和使用安全产生的危害。并借助氙灯老化和UV荧光紫外老化两种人工气候老化试验,研究了劣质增塑剂对硅酮密封胶性能的影响。试验结果表明,两种方法配合使用可以有效鉴别硅酮密封胶质量的优劣。The article introduces current situation of domestic standards of silicone sealant for building use, and analyzes the harms of abusing inferior plasticizer to curtain wall quality and service safety. It also studies the influence of inferior plasticizer on silicone sealant performance with the help of artificial weathering aging tests： xenon arc aging and fluorescence UV aging. The testing results show co-using of the two testing methods can identify the quality of silicone sealant effectively.
