新型弹性环氧树脂配合物

A New Elastic Compound of Epoxy Resin

本文涉及一种新型弹性环氧树脂配合物的制备及其固化工艺的研究。这种弹性配合物作为柔韧性胶粘剂特别适用于热膨胀系数差别大的材料间的粘接,既有优异的固化特性和粘接力,又具有极好的拉伸特性,该配合物使用期长,固化放热低,固化物柔韧性极高,伸长率大于150%,显示类似橡胶的弹性行为。

A new type of epoxy resin compound,that nerves as a pliable adhesive,especially suitable for bonding different materials whose heat expansion coefficients arc considerably different with each other,is introduced. Both the curing characteristics and the properties of the cured epoxy resin compound were investigated,and the effect of the amount of hardener on tensile properties (strength,elongation) was discussed. In the results, the system exhibits a long pot life and low exotherm, the cured product shows a extremely high flexibility and the ultimate elongation is larger than 150%. with the excellent elasticity preformance, the cured epoxy resin compound behaves as a rubber.
