Abstract
The invention relates to a resin/graphene conductive plastic master as well as a blasting stripping preparation method thereof. The conductive plastic master batch consists of the following components in parts by weight: 10-30 parts of EVA (ethylene/vinyl acetate), 70-80 parts of graphite, 0.7-3 parts of a coupling agent, 0.1-2 parts of a surfactant, 0.2-0.8 part of paraffin and 0.1-0.4 part of an antioxidant. The preparation method comprises the following steps: extruding and pelletizing the components through a twin-screw extruder to obtain EVA/graphite small particles; then, heating water, the resin/graphite conductive master batches, a physical foaming agent and an isolating agent in a high-pressure kettle, and then quickly discharging under low pressure to obtain resin/graphene conductive plastic foamed master batch prepared by a blasting stripping method; and extruding and defoaming the conductive plastic foamed master batch through the twin-screw extruder to obtain the resin/graphene conductive plastic master batch. According to the method, the dissolving capacity of a supercritical physical foaming agent is sufficiently utilized, so that a graphite sheet layer can be stripped by expanding under a sudden pressure release condition when the supercritical physical foaming agent is penetrated into the graphite sheet layer. Due to the existence of the resin, the cluster of graphene is effectively blocked, and the obtained volume resistivity can be 0.005 Ohm.cm, so that the method is suitable for industrial production.
