Abstract

The invention discloses an oxidized graphene polypropylene plastic and a preparation method thereof. The preparation method comprises the following steps: after modifying polypropylene and a fire retardant respectively, adding a lubricant and an antioxidant,and blending to obtain the oxidized graphene polypropylene plastic. According to the preparation method, the technical defect that conventionally mechanical high-strength plastics are low in toughness is broken through, and oxidized graphene is preferably combined with polypropylene by adding oxidized graphene and improving a dispersing process, so that the heat resistance and the strength of the oxidized graphene polypropylene plastic prepared in the invention are improved, the intermiscibility of polypropylene with other functional materials is increased, the preparation method is simple, the raw materials are easily obtained, and the prepared polypropylene plastic product is safe and environmentally-friendly and has preferable popularization and application values.

Description

technical field [0001] The invention relates to the field of plastic preparation, in particular to a graphene oxide polypropylene plastic and a preparation method thereof. Background technique [0002] At present, the electrical casing materials used in our country are still mainly polyvinyl chloride. However, the halogen-containing cables are easy to melt when heated, and the toxic gas produced in the event of a fire seriously threatens the health of the fire victims, and also brings disasters to the rescue work. to hinder. At the same time, the electrical casing made of polyvinyl chloride will generate heat under long-term electrical working conditions, and will easily produce harmful odors that endanger people's health. [0003] Polypropylene is a non-toxic, odorless, tasteless milky white high-crystallization polymer. It is one of the lightest varieties of all plastics at present. It has good heat resistance and its continuous use temperature can reach 110-120 ° C. It h...
