【摘要】 <正> 一、概述 环氧树脂(ER)有优良的性能,广泛地用作浇注材料、喷涂材料和粘合剂等。但通常使用的ER固化后性脆, 冲击强度低,这就大大限制了ER的应用。因此,提高ER的抗冲强度而不显著影响其力学性能和耐热性能,一直是重要的研究课题。更多还原

【Abstract】 Epoxy resins can be toughened by a series of liquid rubber.This paper has been written to review for the chemical reactions between the rubber and the resins,the effect of rubber’s properties and the effect of the matrix’s viscoelasticity on toughening results The toughening mechanism is also been discussed更多还原
