Abstract

In this paper, a synthesis method of epoxy resin toughening agent was presented, then the chemical composition and molecular number were studied, which include the DSC curves analysis, the fracture surface morphology and bonding strength. In addition, the mechanism of epoxy resin toughening agent and the effect of toughening agent's content to bonding strength were studied. The testing results reveal that this toughening agent can form a micro two-phase structure in epoxy-amine system, which results in the stable chemical properties and excellent physical properties.

摘要

本文提出了一种环氧树脂增韧剂的合成方法，随后研究了其化学成分和分子数量，包括DSC曲线分析、断口表面形貌和粘结强度。此外，还研究了环氧树脂增韧剂的作用机理以及增韧剂含量对粘结强度的影响。测试结果表明，这种增韧剂能在环氧-胺体系中形成微观两相结构，从而使化学性能稳定且物理性能优异。
