Abstract

A method for preparing a graphene oxide/white carbon black/rubber nanocomposite by mechanical blending belongs to the composite material field. In the graphene oxide/white carbon black/rubber composite prepared by the method provided by the invention, because graphene and white carbon black are inserted with each other, the self-aggregation of the two fillers is effectively suppressed, and thus a composite having high dispersion, high stripping and nanoscale dispersion is obtained. Not only while the composite has higher modulus and lower rolling resistance, but also the wear resistance of a rubber material is substantially improved, and the modulus and tear resistance of the composite are further improved; at the same time, because of the lamellar structure and good self-recovery capability of the graphene oxide, the rubber material is also imparted with good gas barrier performance and self-healing capability, and the nanocomposite has the incomparable advantages to any traditional fillers. The method provided by the invention is simple and easy to implement, low in cost and easy to industrialize, has wide suitability and better economic benefits and social benefits.

Description

technical field [0001] The present invention relates to a preparation method of graphene oxide / white carbon black / rubber nano-composite material with high exfoliation, high dispersion and strong interfacial bonding, in particular to the combination of emulsion compounding and flocculation process, or the combination of emulsion compounding and spray drying process, and Mechanical blending method to prepare graphene oxide / silica / 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, but with the dwindling of petroleum resources, the production and application of carbon black completely dependent on petroleum encounter challenges. The research on alternative materials for rubber reinforcement and non-petroleum resources that can replace carbon black has gradually become one of the importa...
