Description

technical field [0001] The invention relates to the technical field of polypropylene materials, in particular to a graphene oxide modified polypropylene composite material. Background technique [0002] As a thermoplastic resin with excellent comprehensive performance, polypropylene (PP) has the advantages of abundant raw material sources, good mechanical properties, low density and good chemical stability. At present, it is widely used in chemical industry, construction, electric power, automobile, machinery, textile, medical , packaging and building materials and furniture industries have been widely used. However, traditional polypropylene has low mechanical strength, low oxygen index, is easy to burn, has poor thermal stability, and poor dimensional stability. The existing polypropylene composite materials have low strength, heat resistance, flame retardancy and stability Often cannot meet the needs of society. In order to overcome and improve the defects of polypropyl...
