Abstract

The invention discloses a wear-resisting and shock-resisting polypropylene material for an inner barrel of a washing machine and a preparation method thereof. The wear-resisting and shock-resisting polypropylene material is prepared from, by weight, 90-110 parts of polypropylene, 20-30 parts of acrylic acid, 3-5 parts of lauroyl peroxide, 8-10 parts of xylene, 40-50 parts of acetone, 20-25 parts of ethylene-trifluorochlor oethylene copolymer, 5-7 parts of tetra-(2-ethylhexyl)pyromellitate, 7-9 parts of cotton stalk bark fiber, 4-6 parts of aerosol, 5-7 parts of zinc stearate, 2-4 parts of dibasic lead stearate, 6-8 parts of polyethylene wax, 8-10 parts of epoxy linseed oil, 15-20 parts of sub-white corundum fine powder, 10-12 parts of hollow glass bead, 7-9 parts of graphene oxide, and 5-7 parts of nepheline powder, and so on. Through blending and modifying polypropylene resin by ethylene- trifluorochlor oethylene copolymer, the mechanical strength and wear resistance of the composite polypropylene material are improved, and the corrosive resistance and creep resistance are also improved; acrylic acid is grafted with modified polypropylene, so as to improve the compatibility between the mixed filler consisting of sub-white corundum fine powder, graphene oxide and others, and organic resin, promote the wear resistance, shockproof and anti-impact performances of the composite materials.

Description

technical field [0001] The invention relates to a composite material, in particular to a wear-resistant and anti-vibration polypropylene composite material for an inner barrel of a washing machine and a preparation method thereof. Background technique [0002] Polypropylene has outstanding advantages such as low density, good mechanical balance, chemical corrosion resistance, easy processing, high heat distortion temperature and low price, and has developed rapidly. Its biggest disadvantage is poor willfulness. The development of copolymerization technology, especially the advent of copolymerized polypropylene resin, has expanded the application field of polypropylene, and is widely used in washing machines and other household appliances to make various parts. However, polypropylene material has poor wear resistance and impact resistance, so it needs to be modified when it is used in the inner drum of the washing machine. The traditional modification method is to toughen po...
