Abstract

The invention discloses a graphene natural rubber oil-resistant mixed foaming material and a preparation method thereof. The material is prepared from the following raw materials in parts by weight: 36-44 parts of natural rubber, 28-33 parts of nitrile butadiene rubber, 8.5-11.5 parts of cis-1,4-polybutadiene rubber, 14-16 parts of polyvinyl chloride resin, 4-6 parts of white carbon black, 1.2-1.5parts of silicone oil, 1.7 to 2.1 parts of zinc oxide, 1.4 to 1.8 parts of zinc stearate, 1.3 to 1.6 parts of stearic acid, 2.3 to 2.9 parts of a cross-linking agent, 2.5 to 3.5 parts of graphene, 1.9 to 2.5 parts of a foaming agent and 1.8 to 2.4 parts of a flow aid. After being soaked in a hydrocarbon oil solvent (such as butyl acrylate), the product still maintains high tensile strength and high elongation at break, is not easy to react with the hydrocarbon oil solvent, and has good oil resistance and good mechanical properties; the compression set rate, the rebound resilience and the mechanical property are good; and wear resistance is good.

Description

technical field [0001] The invention relates to the technical field of rubber products, in particular to a graphene natural rubber oil-resistant mixed foaming material 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, etc...
