Problems solved by technology

The usual practice is to use a certain amount of carbon black to improve the wear resistance of rubber materials on the basis of white carbon black filling, but this often requires a higher amount of carbon black, and it will increase the rolling resistance of the rubber material and reduce the wear resistance. The tear performance is reduced at the cost, and at the same time it cannot meet the requirements of green environmental protection

Abstract

The invention relates to a method for preparing a graphene oxide / white carbon black / rubber nanocomposite, which adopts a solution blending method or a mechanical blending method. In the graphene oxide / white carbon black / rubber nanocomposite prepared by the method provided by the invention, graphene and white carbon black are inserted with each other to effectively effective the aggregation of the two fillers, so as to obtain a highly-dispersed highly-stripped nano-sized composite. Not only the composite has high modulus and low rolling resistance, but also the wear resistance of a rubber material is greatly improved, and the modulus and tear resistance of the composite are further improved; in addition, due to the lamellar structure and good self-recovery capability of graphene oxide, the rubber material is also endued with good gas barrier performance and self-recovery capability, and the nanocomposite has the advantages that cannot be matched by any traditional filler. The method provided by the invention is simple and feasible, and suitable for industrial production, and has low cost, wide application range and good economic and social benefits.

Description

Technical field [0001] The present invention relates to a preparation method of graphene oxide / white carbon black / rubber nanocomposite with high exfoliation, high dispersion and strong interface bonding, in particular to the combination of emulsion compounding and flocculation process, or the combination of emulsion compounding and spray drying process, and The mechanical blending method is used to prepare graphene oxide / white carbon black / rubber nanocomposites. Background technique [0002] In the rubber industry, the largest and most versatile fillers are nano-scale carbon black and white carbon black. Carbon black is the most important reinforcing filler in the rubber industry. However, with the ever-decreasing petroleum resources, the production and application of carbon black that are completely dependent on petroleum are facing challenges. The research on the substitute materials of non-petroleum resources that can be used for rubber reinforcement and can replace carbon bl...
