Preparation method of graphene/polyvinyl chloride composite material

The invention discloses a preparation method of a graphene/polyvinyl chloride composite material. The preparation method comprises the following steps of 1, preparing modified graphene, 2, preparing awater-based emulsion, 3, preparing modified polyvinyl chloride resin, and 4, preparing the graphene/polyvinyl chloride composite material. The method disclosed by the invention is low in cost, simpleto prepare and easy for industrial batch production, solves the problem that the traditional waterproof material is easy to crack, and utilizes the graphene to be uniformly dispersed in the polyvinylchloride resin to prepare the waterproof corrosion-resistant composite material under the synergistic effect of the graphene and the polyvinyl chloride resin. 本发明公开一种石墨烯/聚氯乙烯复合材料的制备方法。包括：一、改性石墨烯的制备；二、水性乳液的制备；三、改性聚氯乙烯树脂的制备；四、石墨烯/聚氯乙烯复合材料的制备。本发明的方法成本低、制备简单，易于工业化批量生产，并且解决了传统防水材料易产生开裂的问题，利用石墨烯在聚氯乙烯树脂中均匀分散，并且在它们协同作用下制得防水耐腐蚀的复合材料。
