The graphene natural rubber polymer surfboard composite foamed materialis prepared from the following raw materials in parts by weight: 47-53 parts of natural rubber, 32-36 parts of butyl rubber, 8.5-11.5 parts of isoprene rubber, 5-7 parts of a nano medium, 2-2.5 partsof graphene, 3.5-4.5 parts of fumed silica, 1.5-2 parts of zinc oxide, 3-4 parts of a heat stabilizer, 2-2.5 parts of a cross-linking agent, 3-4 parts of a flow aid and 2-2.2 parts of a foaming agent.The density of the graphene natural rubber polymer surfboard composite foamed material is far lower than that of a common natural rubber foamed material, and the graphene natural rubber polymer surfboard composite foamed material has ultralight weight; the water absorption rate is far lower than that of the common natural rubber foamed material, the tensile strength is far higher than that of thecommon natural rubber foamed material, the mechanical property is good, and the graphene natural rubber polymer surfboard composite foamed material is very suitable to be taken as a surfboard material and has a wide market application prospect.

Description

technical field [0001] The invention relates to the technical field of rubber products, in particular to a graphene natural rubber polymer surfboard composite 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 tetrachlor...
