建筑结构胶的耐湿热老化性能研究

Study on wet and heat ageing resistance of the building structural adhesives

耐湿热老化是建筑结构胶的重要性能指标,正在受到越来越多的关注。研究了不同种类的固化剂对改性环氧树脂类建筑结构胶的耐湿热老化性能的影响,同时也对增韧剂、无机填料及助剂等因素进行了探讨。采用自制的固化剂所配制的建筑结构胶耐湿热老化性能优良,完全满足国家标准的要求。

Wet and heat ageing resistance is one of the most important properties of the building structural adhesives to which has been paid more attention recently. The influences of curing agents on the resistance of the epoxy adhesives are dicussed, and the comprehensive index such as flexibilizer, inorganic filler, auxiliary agent and so on are also studied, A kind of curing agent is prepared and thereof consists of the part of the adhesives which have showed good performance in the ageing test process.
