AI Technical Summary
Existing rebar anchoring adhesives cannot simultaneously improve strength and toughness during the toughening process, resulting in insufficient fatigue resistance and impact resistance in railway engineering, and failing to meet the requirements of high-frequency dynamic loads and high-temperature environments.
By combining a 'island structure' toughening agent with a grafted rubber particle toughening agent, in-situ phase separation is formed through the curing of a two-component epoxy resin. Combined with rubber particles grafted with terminal epoxy hyperbranched polyether, multiple toughening effects are achieved.
While ensuring strength, it significantly improves toughness and impact resistance, enhances the fracture energy of the colloid, and meets the high-performance requirements of railway engineering.
