High-elasticity modified rubber

The invention discloses high-elasticity modified rubber, comprising the following raw materials in parts by weight: 97-103 parts of modified natural rubber, 5-8 parts of methyl phenyl vinyl silicone rubber, 10-13 parts of chloroprene rubber, 1.5-1.9 parts of a titanate coupling agent KR-38S, 12-16 parts of polyamide fiber, 1.3-1.8 parts of DCP (dicumyl peroxide), 2-2.4 parts of sulphur, 1.4-1.7 parts of N,N'-meta phenylene maleimide, 2.1-2.4 parts of magnesium oxide, 37-42 parts of magnesium carbonate, 36-39 parts of hard clay, 10-13 parts of furnace black, 12-16 parts of magnesium hydrate, 3-5 parts of diphenyl phosphate, 7-9 parts of melamine cyanurate, 8-12 parts of trioctyl trimellitate, 1.2-2.3 parts of an anti-aging agent SP and 1.1-1.4 parts of an anti-aging agent BLE. The high-elasticity modified rubber is good in elasticity, and can be widely applied to rubber products.
