研究了具有耐高温性、阻燃性、增韧性和耐烧蚀性等多种功能的双重可调性R系列环氧树脂(EP)新型固化剂,该固化剂与EP的配比范围较宽且可调,该固化剂分子中增韧链段的比例范围较宽且可调。利用其多功能性和双重可调性,可以很快地优选出具有特定性能要求的一系列胶粘剂(如具有耐高温性、高韧性和高强度等性能的胶粘剂),并且有望开辟出梯度功能固化剂、梯度功能EP胶粘剂和梯度功能复合材料等新领域。
A novel dual-adjustable R-series epoxy resin (EP) curing agent with various functions such as high temperature resistance, flame retardancy, toughening and ablation resistance was studied. The curing agent has a wide range of EP And is adjustable. The proportion of the toughening segment in the curing agent molecule is wide and adjustable. With its versatility and dual adjustability, a range of adhesives with specific performance requirements, such as adhesives with properties of high temperature resistance, high toughness and high strength, can be quickly optimized and is expected to open up a gradient-function cure Agents, graded EP adhesives, and gradient functional composites.
