摘要
对比了两种硅烷偶联剂KH-560和KH-792对所制备的单组分室温硫化硅酮密封胶粘结性能、拉伸模量和断裂伸长率的影响,结果表明,随着体系中KH-792占比的增加,单组分室温硫化硅酮密封胶的粘结性能、拉伸模量和断裂伸长率都得到了有效提升,密封胶的实用性得到了改善。
The article compares the influence of silane coupling agent KH-560 and KH-792 on the bonding strength,tensile modulus and elongation at break of the single component RTV silicone sealant produced with them.Results show:with the increase of KH-792 proportion in the system,the bonding strength,tensile modulus and elongation at break of single component RTV silicone sealant are enhanced effectively,and the practicability of the sealant is improved as well.
