摘　　要：硅酮嵌缝密封材料具有卓越的耐候性、优异的温度适应性和环境友好性等特点,现已被广泛应用于混凝土结构的接缝处理,特别适用于长线连续浇筑的混凝土接缝。针对现有硅酮嵌缝密封材料技术标准存在差异,在系统分析国内外硅酮嵌缝密封材料技术要求的基础上,提出了混凝土接缝硅酮嵌缝密封材料的性能要求。从跟随性、黏结性和耐久性三方面,提出了实现硅酮嵌缝密封材料高性能化的技术途径,阐述了混凝土接缝硅酮嵌缝密封材料应用现状及存在问题。结合国内外高性能硅酮嵌缝密封材料研究进展,指出了我国高性能硅酮嵌缝密封材料的发展方向。Silicone sealant is widely used in the joint of concrete structure, especially for the long term continuous casting concrete structure, because of the excellent weather ability, thermal adaptability and environment - friendly etc. According to the differences of technical standards in silicone sealants, performance requirements of silicone sealants in concrete joint is proposed based on analyzing the technical requirements of silicone sealants. From the three aspects of following, bonding and durability, technology methods to a- chieve high - performance of silicone sealants are proposed, and expounded the application status and problems of silicone sealants in concrete joint.Combining with research progress of high - performance silicone sealants, the development trend of high performance sili- cone sealing materials in our country is pointed out.
