Problems solved by technology

[0004] With the continuous development of society, the existing properties of rubber can no longer meet the needs of the people. Therefore, graphene rubber composite materials are displayed in front of people. Because graphene has excellent physical and chemical properties, it is used as a rubber nanofiller for rubber products. High performance and functionalization have special significance. The common production methods of graphene rubber in industry include latex blending method, mechanical mixing method and solution blending method. For latex blending method, graphene or graphene oxide The dispersion is added to the rubber latex and stirred evenly, and then demulsified, dried and vulcanized to obtain a graphene rubber composite. Agglomeration is easy to occur during the process, which affects the performance of composite materials

Abstract

The invention discloses a graphene rubber composite material and a preparation method thereof, wherein the composite material basically comprises, by mass, 0.5-10 parts of graphene oxide, 100 parts ofa rubber matrix, 1-5 parts of a water solvent, 1-5 parts of a reducing agent, 1-5 parts of a modifier, 1-4 parts of a vulcanization accelerator, 3-6 parts of zinc oxide, 0.5-4 parts of an anti-agingagent, and 1000-2000 parts of deionized water. According to the present invention, by adding the reducing agent into the graphene rubber composite material, graphene can be well dispersed in the dispersion system so as to effectively avoid the occurrence of graphene agglomeration and improve the mechanical properties of the composite material; and the graphene is modified by adding the modifier, such that the modified composite material can greatly improve the modulus and the tensile properties of the product.
