Abstract

The invention relates to the field of preparation of polypropylene composite materials, in particular to an environment-friendly and flame-retardant polypropylene composite material. The environment-friendly and flame-retardant polypropylene composite material is prepared from 100 parts of polypropylene, 0.1-2 parts of modified graphene, 0.5-3 parts of modified carbon nano tubes, 10-20 parts of an inorganic flame retardant, 5-10 parts of a compatilizer, 3-10 parts of a toughening agent, 0.1-0.3 parts of an antioxidant and 0.1-0.3 parts of a heat stabilizer. Graphene, the carbon nano tubes and the inorganic flame retardant are added to polypropylene resin, and a brand-new flame retardant system is formed; dispersing performance of graphene in a polymer system is improved through modification of graphene; migration of combustible matter in a polymer matrix can be effectively inhibited; a compact protective carbon layer is formed on the surface of the polymer matrix by graphene in the burning process of the composite material, and finally, the flame-retardant effect is achieved.

Description

technical field [0001] The invention relates to the field of polypropylene composite material preparation, in particular to an environment-friendly, flame-retardant, chlorine- and bromine-free halogen-free polypropylene composite material and a preparation method thereof. Background technique [0002] Polypropylene is a crystalline high polymer with the characteristics of light weight, non-toxic, odorless, etc., and has high mechanical strength. It has better transparency and tensile strength than polyethylene, especially has unique bending characteristics of repeated bending resistance , and thus has been highly supported as a plastic material for replacement vehicle components. In addition, polypropylene is excellent in high rigidity, impact resistance, transparency and high fluidity, and has been widely used not only in the automobile industry but also in household appliances, disposable syringes, transparent containers, cleaning non-woven fabrics, packaging Raw material...
