摘要
以端硅烷改性聚醚为基础聚合物,加入增塑剂、填料、触变剂、耐老化助剂、催化剂等助剂,通过对各组分进行严格的筛选和对比研究,制备了一种装配式建筑专用双组分MS胶。该密封胶具有低模量、高断裂伸长率、高弹性恢复率等性能特点,配合专用底涂使用,能够满足装配式建筑填缝的性能要求。
Through strict screening and comparative study of each component,a kind of two-component MS sealant special for prefabricated buildings is prepared.The sealant uses terminated silicone modified polyether as basic polymer,adds plasticizer,filler,thixotropic agent,anti-aging assistant,catalyzer and other auxiliaries.The prepared sealant possesses characteristics of low modulus,high elongation at break,high elastic recovery rate et cetera.Combining with special prime coat,it can meet the performance requirements of joints filling for prefabricated buildings.
