Method for preparing graphene/rubber composite material

Abstract

The invention belongs to the technical field of rubber wet-method mixing, and in particular relates to a method for preparing a graphene/rubber composite material. The method comprises the following three steps of preparing a rubber master batch mixed solution, preparing a rubber master batch and preparing a composite material, namely firstly, preptreating packing by using stirring and ultrasonic atomization techniques so as to form a packing emulsion, ejecting the packing emulsion to the surface of a high-temperature article through high gas pressure by using a packing pre-dispersion sudden heating crushing technique, performing sudden heating crushing on packing emulsion droplets so as to achieve secondary dispersion on the packing in a rubber substrate, further implementing a high-temperature evaporation drying technique, performing sudden heating crushing dispersion on a packing pre-dispersed material, placing prepared wet-method mixing rubber in a high-temperature environment, performing instantaneous evaporation on moisture of the rubber, performing high-quality dispersion on the cured packing in the rubber substrate, and finally preparing a packing/rubber composite material by using a common sealed mixing machine. The method is scientific and reliable in principle, practical, simple and convenient to prepare, high in preparation efficiency, wide in application prospect and good in environmental-friendliness.
