摘　　要：开发了一款常温生产的单组分硅烷改性聚醚密封胶。试验结果表明,采用30份活性纳米碳酸钙作为抗流挂剂,2份乙烯基硅烷作为除水剂,0.1份复配催化剂[m(辛酸亚锡)∶m(双吗啉胺)=2∶8],可制得触变性好、回弹率高、表干快、黏度低和耐候性优良的单组分硅烷改性聚醚(MS)密封胶,适合装配式建筑拼接缝的防水密封。This paper developed a one-component silane modified polyether sealant produced at room temperature. The test results show that using 30 parts of active nano-calcium carbonate as anti-sag agent,using 2 parts of vinyl silane as water scavenger,and using 0.1 part of stannous octoate and bimorpholine amine compound catalyst(2∶8),a one-component MS sealant with good thixotropy,high elastic recovery,fast surface drying,low viscosity and excellent weather resistance can be obtained,which is suitable for waterproof sealing of prefabricated building joints.

关 键 词：装配式建筑 MS密封胶 高回弹率 低黏度
