Problems solved by technology

However, carbon black also has some disadvantages in the process of use, for example, serious processing pollution, high energy consumption, and long mixing time
Also, carbon black is a petrochemical product, which is highly dependent on petroleum, and its continuous consumption in large quantities is bound to be useless to alleviate the growing tension in petroleum resources.

Abstract

A preparation method of a high-performance graphene oxide / carbon black rubber nanocomposite material belongs to the field of rubber composite material. By combining technologies of compounding of graphene oxide and carbon black and rubber latex, composite emulsion co-flocculation and mechanical blending, the graphene oxide / carbon black rubber nanocomposite material is prepared. By emulsion compounding, graphene oxide and carbon black are intercrossing so as to effectively inhibit aggregation of the two fillers. Then, the highly-dispersed, highly-stripped and nanoscale-dispersed composite material is obtained. The rubber composite material prepared by the method can fully perform traditional advantages of a spherical filler and can perform effects of graphene oxide to the maximum. By the preparation method, mechanical strength, wear resistance and wet-skid resistance of the rubber composite material are enhanced, and thermogenesis is reduced. The preparation method is simple and feasible, is low-cost, is easy for industrialization, has a wide application range, and has good economic benefit and social effect.

Description

[0001] Technical field: [0002] The invention relates to a preparation method of a high-performance graphene oxide / carbon black rubber nanocomposite material, which particularly solves the problem that graphene oxide and carbon black are easily agglomerated and unevenly dispersed in rubber in a traditional mixing method. In particular, it relates to the combination of emulsion compounding and flocculation process and the method of mechanical blending to prepare graphene oxide / carbon black rubber composite material. Background technique [0003] Due to its unique high elasticity and viscoelasticity, rubber composite materials are widely used in many fields such as tires, conveyor belts, shock absorbers, seals, and wave-absorbing dampers. They are irreplaceable strategic materials in my country's national economic development. Most synthetic rubbers have relatively poor strength and wear resistance. Even though natural rubber itself has high strength, it still needs to be reinf...
