室温固化耐高温胶粘剂的研究

以环氧氯丙烷和对氨基苯酚为主要原料制备了多官能度的环氧树脂(EP-005),并采用自制的复配固化剂、纳米SiO2、特殊的增韧剂和特种填料等进行改性,制得了一种结构加固用的建筑耐温结构胶。实验结果表明,该胶粘剂可常温固化,加固后的构件可在常温与高温(150℃)环境中长期使用;该胶粘剂在150℃时的剪切强度为17.28 MPa,常温拉伸强度为42.60 MPa,常温压缩强度为90.63 MPa;该胶粘剂具有卓越的综合性能,并已成功用于建筑工程等领域中。

Study on high temperature resistance adhesive for room temperature curing

The polyfunctionality epoxy resin(EP-005) was prepared with epichlorohydrin and aminophenol as main materials.It was modified by a self-made compound curing agent,nano-SiO2,special toughener and filler and so on,a building structure adhesive of high temperature resistance was prepared for strengthening structure.The experimental results showed that this adhesive could cure at room temperature,after strengthening parts should being used for longer term from room temperature to 150 ℃.The shearing strength at 150 ℃ was 17.28 MPa,the tensile strength at room temperature was 42.60 MPa,the compression strength at room temperature was 90.63 MPa.This adhesive had excellence synthetical properties,and was used successfully in constructions engineering fields.
