摘要
采用不同温度下力学性能、热变形温度和玻璃化转变温度三种方法,考察了两种环氧建筑结构胶的耐热性能,并对结果进行了比较。试验结果表明:结构胶的三种不同耐热性能测试方法之间存在一定联系,温度升高会显著降低结构胶的强度和抗形变能力,热变形温度(B法)和玻璃化转变温度均相近的两种结构胶,高温力学性能却存在显著差别。
The heat resistance performance of two structural epoxy adhesives was measured and contrasted by three methods： mechanical properties at different temperatures,heat deformation temperature,glass transition temperature.The test results show that there are connections between three methods,higher temperature will significantly reduce the strength and deformation-resistance ability of structural adhesive,structural adhesive with similar heat deformation temperature（B method） and glass transition temperature could have notable different mechanical properties at high temperature.
