Problems solved by technology

[0002] Epoxy resin is a linear thermoplastic substance, which forms a three-dimensional network structure after being cross-linked with a curing agent. Decreased fracture energy and fracture toughness
Epoxy adhesives have good bonding strength, thermal stability and aging resistance, but they have low bonding strength to metal substrates, poor toughness, low impact strength, poor water resistance, salt spray resistance, and high temperature resistance.
Bismaleimide resin has good heat resistance, but it is brittle and has low peel strength
The application of bismaleimide resin in epoxy resin adhesive can improve its high temperature resistance, but the toughening of bismaleimide resin will easily lead to the decrease of the impact resistance of epoxy resin adhesive

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a high-performance resin-based adhesive and its preparation method and application. Background technique [0002] Epoxy resin is a linear thermoplastic substance, which forms a three-dimensional network structure after being cross-linked with a curing agent. Fracture energy and fracture toughness decrease. Epoxy adhesives have good bonding strength, thermal stability and aging resistance, but they have low bonding strength to metal substrates, poor toughness, low impact strength, poor water resistance, salt spray resistance, and high temperature resistance. Bismaleimide resin has good heat resistance, but it is brittle and has low peel strength. The application of bismaleimide resin in epoxy resin adhesive can improve its high temperature resistance, but the toughening of bismaleimide resin will easily lead to the decrease of the impact resistance of epoxy resin a...
