Description

technical field [0001] The invention relates to the technical field of rubber products, in particular to a rubber elastic polymer material with high elasticity of graphene and a preparation method thereof. Background technique [0002] Natural rubber (NR) is a natural polymer compound with cis-1,4-polyisoprene as the main component, and 91% to 94% of its components are rubber hydrocarbons (cis-1,4-polyisoprene Diene), and the rest are non-rubber substances such as protein, fatty acid, ash, sugar, etc. It is generally flake solid, relative density 0.94, refractive index 1.522, elastic modulus 2-4MPa, softens at 130-140°C, sticky and soft at 150-160°C, and begins to degrade at 200°C. It has high elasticity at room temperature, slightly plastic, and crystallizes and hardens at low temperature. It has good alkali resistance, but not strong acid resistance. Insoluble in water, lower ketones and alcohols, can swell in non-polar solvents such as chloroform, carbon tetrachloride,...
