A high-curing-rate sealant for new energy vehicles and a preparation method thereof

Abstract

The application discloses a high-curing-rate sealing glue for new energy vehicles and a preparation method thereof, and belongs to the technical field of adhesive preparation. The high-curing-rate sealing glue for new energy vehicles comprises components A and B. The preparation raw materials of the component A comprise a double-bond-containing polyurethane oligomer, glycerol, a magnetic sensing filler, diisodecyl phthalate, fumed silica and p-toluenesulfonyl isocyanate; and the preparation raw materials of the component B comprise an MDI type isocyanate prepolymer, a composite catalyst, heavy calcium carbonate and diisodecyl phthalate. The sealing glue has a long operable time, a fast curing rate, excellent adhesion and moisture and heat resistance.
