摘要
随机选取了8种硅酮结构密封胶,通过热老化试验,研究了硅酮结构密封胶的粘结强度、伸长率等力学性能随老化时间延长的变化规律,得出结构胶相对粘结强度随热老化时间延长的变化关系呈二次函数曲线,同时给出了该二次函数曲线的方程式。
This paper analyses the changing relationship of the bonding strength, elongation and other mechanical performances of structural silicone sealants with the extension of aging time by thermal aging tests of 8 randomly selected silicone sealants. It draws the conclusion that the relationship between the bonding strength of the structural silicone sealants and the aging time is a quadratic function curve. It also points out the equation of the function.
