摘要

采用差热分析方法研究了AF-2氨基酚和L-18氨基酰胺硬化剂在低聚硅氧烷改性剂作用下的固化过程及其组成。研究发现，每100 wt pts ED-20中加入10 wt pts的低聚硅氧烷改性剂对所有研究组合物的固化过程温度范围没有影响。使用低聚硅氧烷改性剂和硬化剂组合物可以获得具有高弯曲强度和与金属基材（St3）粘合强度的环氧聚合物。

The Effect of Oligosiloxanes on the Curing Process of an Epoxy Resin with a Composition of Aminoamide Hardeners and Properties of the Epoxy Polymer

The curing process of an ED-20 epoxy resin with AF-2 aminophenol and L-18 aminoamide hardeners and their composition in the presence of an oligosiloxane modifier is studied by differential thermal analysis. It is found that introducing an oligosiloxane modifier in the amount of 10 wt pts per 100 wt pts of ED-20 has no effect on the temperature range of the curing process for all the studied compositions. The use of an oligosiloxane modifier and a composition of hardeners makes it possible to obtain epoxy polymers with high bending strength and adhesion strength to a metal substrate (St3).
