Epoxy-terminated polyurethane flexibilizer for bridge and tunnel pavement, and preparation and use methods thereof
PendingCN119529218AMeet long-term storage stability requirementsgood compatibilityClimate change adaptationEpoxyEndcapping
The invention relates to an epoxy-terminated polyurethane flexibilizer for bridge and tunnel pavement, and a preparation method and a use method thereof, and the flexibilizer is prepared by terminating a polyurethane prepolymer through an epoxy group of an epoxy compound under the catalytic action of nano-modified imidazole; wherein an epoxy group reacts with an NCO group at the end part of a polyurethane prepolymer, and a five-membered ring structure with high cohesive energy is introduced into a polyurethane molecular chain. A main chain of the epoxy-terminated toughening agent contains a five-membered ring structure, and the epoxy-terminated toughening agent is prepared from an epoxy group and an isocyanate group through catalysis of nano-modified imidazole at a relatively low temperature. Due to the fact that the cohesive energy of the five-membered ring is high, the steric hindrance effect is large, good high and low temperature stability is achieved, and the damping temperature range is wide. And after being cured, the curing agent has the properties of high-temperature rutting resistance, medium-temperature fatigue resistance, low-temperature crack resistance and the like, and the problem of insufficient toughness of an epoxy mixture in conventional pavement is solved.
