摘要
在常温条件下,环氧树脂本身不容易固化,也不具有一系列优良的性能;而适当使用固化剂可以使得环氧树脂固化,通过交联反应生成立体网状结构的物质,从而使铸工胶获得一系列的性能优势。为了验证不同环氧固化剂对环氧铸工胶力学性能的影响,采用T-31型、T-31E型和T31-B 4型3种环氧固化剂来制备铸工胶,通过控制变量法进行分析、验证。结果表明:使用T-31型环氧固化剂制备的铸工胶性能更为优异,综合力学性能强度在其质量分数为20%时达到最大值。
Under normal temperature conditions,epoxy resin itself is not easy to solidify,nor does it have a series of excellent properties.Appropriate use of the curing agent can solidify the epoxy resin and generate a three-dimensional network structure through the cross-linking reaction.In this test,three epoxy curing agents,T-31 type,T-31E type and T31-B 4 type,were used to prepare casting glue,and the analysis was carried out by the controlled variable method.The results showed that the caster glue prepared by using T-31 epoxy curing agent had better performance,and the comprehensive mechanical property strength reached the maximum value when its dosage is 20%.
