摘要
采用α,ω-二羟基聚二甲基硅氧烷、多烷氧基硅基封端聚二甲基硅氧烷、活性碳酸钙、α,ω-二甲基聚二甲基硅氧烷、催化剂等作为原料,制备了一种等比例缩合型双组分室温硫化硅橡胶,并讨论了催化剂用量、密封胶固化时间和混合比例对该有机硅密封胶性能的影响。
A kind of bi-component equally proportional condensed silicone rubber,which vulcanized at room temperature was prepared by the raw materials such as α,ω-dihydroxy PDMS,multi-alkoxy silicone based blocking PDMS,activated calcium carbonate,α,ω-dimethyl PDMS,and catalyst etc.The article discussed the influence of catalyst dosage,sealant curing time and mixture ratio on the performance of this silicone sealant.
