High-performance rubber copolymerized cyclic diene blending material and preparation method thereof

The invention relates to a high-performance rubber copolymerized cyclic dialkene blending material and a preparation method thereof. The preparation method comprises the following steps: carrying out copolymerization reaction on rubber and cyclic dialkene at 170-190 DEG C for 1-3 hours according to a mass ratio of (6-12): (88-94), and then cooling to 40-50 DEG C to obtain a copolymer; the preparation method comprises the following steps: uniformly mixing a copolymer, a cocatalyst, a time control agent and an antioxidant according to a mass ratio of (94-98): (0.5-2): (0.5-2): (1-2) to obtain a component A; uniformly dispersing the copolymer, the main catalyst and the antioxidant according to the mass ratio of (94-98): (1-3): (1-3) to obtain a component B; then mixing the component A and the component B according to a mass ratio of 1: 1, carrying out a curing reaction at 70-90 DEG C for 1-3 min, and naturally cooling to obtain the high-performance rubber copolymerized cyclic diene blending material with excelle
