Description

technical field [0001] The invention relates to the technical field of polypropylene materials, in particular to a heat-resistant and highly flame-retardant 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, polypropylene has a low oxygen index, is easy to burn, and has poor thermal stability. The heat resistance and flame retardancy of existing polypropylene composite materials often cannot meet the needs of society. In order to overcome and improve the defects of polypropylene, polypropylene is usually modified by blending and reinforcing fillin...
