Abstract

The invention discloses a flame-retardant two-component adhesive, which comprises A component and B component. The A component and the B component are respectively composed of the following substances by weight percentage. A component: modified isocyanate prepolymerized Body 55‑85%, flame retardant a 6‑20%, filler a 8‑22% and stabilizer 1‑3%; B component: polyol 30‑75%, amine 3‑10%, coupling agent 2 ‑5%, flame retardant b 10‑30%, filler b 10‑25%; the weight ratio of component A to component B is 1:1. The invention adopts the hydroxyl-terminated phosphorus copolymer to modify the polyurethane prepolymer, and prepares the polyurethane prepolymer with flame retardant performance, which has flame retardancy when used as an adhesive, while maintaining the traditional two-component polyurethane adhesive strength and thermal conductivity. The flame-retardant two-component adhesive of the present invention has good application in the bonding of new energy battery structures and the like, and has high bonding strength to plastics and metals.

Description

Technical field [0001] The present invention relates to the field of adhesives, and more particularly to a flame retardant double-component adhesive and a preparation method thereof. Background technique [0002] Flame retardant double-component polyurethane adhesive for new energy cells, require high strength, excellent thermal conductivity, and can be suitable for bonding, solvent corrosion resistance and high temperature resistance. Compared to traditional adhesives, the two-component adhesive has high temperature and good thermal conductivity, and the application on new energy batteries can solve some of the limitations facing traditional curing adhesives. However, in some special scenes, there is a need to have flame retardancy, and the flame retardant adhesive can improve the safety and reliability of the battery in addition to high-strength and thermally conductive performance. Inventive content [0003] The present invention provides a flame retardant double-component ad...
