Problems solved by technology

However, at present, mechanical blending and solution blending methods are commonly used for the compounding of graphene oxide and rubber materials. It is difficult to peel off graphene oxide and disperse it uniformly in the rubber matrix by mechanical blending. Break graphite oxide flakes; although solution blending can peel off graphene oxide and evenly disperse it, the use of a large amount of organic solvents causes environmental pollution and the cost is huge

Abstract

The invention relates to a preparation method of a high-performance graphene oxide / solution polymerized styrene-butadiene rubber composite material, belonging to the field of rubber composite materials. The preparation method comprises the following steps: preparing a solution polymerized styrene-butadiene rubber emulsion, compounding graphene oxide with the solution polymerized styrene-butadiene rubber emulsion, co-flocculating the composite emulsion, and mechanically blending. The solution polymerized styrene-butadiene rubber emulsion has the advantages of simple preparation technique and low cost. By using the emulsion compounding, the graphene oxide has high peeling property and high dispersity. The graphene oxide / solution polymerized styrene-butadiene rubber master batch can be directly machined or combined with solution polymerized styrene-butadiene rubber solid, and can also be doped with other fillers to prepare the high-performance solution polymerized styrene-butadiene rubber nano composite material.
