Research progress on chemical modification methods of epoxy adhesive
Epoxy resin is a widely-used adhesive material,but the traditional epoxy adhesive often fails to meet various performance requirements of today,and needs to be modified before application.In this paper,the chemical modification methods of epoxy adhesive in the recent ten years,such as the synthesis of new epoxy resins and curing agents,composite modification,etc.were categorized and summarized.Based on the research hotspots in recent years,the future development direction of epoxy adhesive was analyzed and prospected.
