Problems solved by technology
[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, the polypropylene materials currently on the market have poor fluidity and cannot meet the basic needs of the market.

Embodiment Construction
[0012] The present invention will be described in detail below in conjunction with embodiments.
[0013] A polypropylene composite material for a washing machine, comprising 50 to 55 parts of polypropylene, 30 to 40 parts of dicumyl peroxide, 10 to 15 parts of talcum powder, and 5 to 10 parts of antibacterial Oxygen.
[0014] Among them, polypropylene is made by mixing polypropylene copolymer, toughening masterbatch, cooling masterbatch and additives.
[0015] Among them, the addition amount of toughening masterbatch and cooling masterbatch is 4.5% and 3.5% respectively.
[0016] Among them, the copolymerized polypropylene, the toughening masterbatch, the cooling masterbatch, and the mixture of auxiliary agents are also added with a molecular weight regulator.
[0017] Wherein, the preparation method of the composite material comprises the following steps: uniformly mixing polypropylene, dicumyl peroxide, talcum powder, and an antioxidant, extruding and granulating by an ext...

The invention discloses a polypropylene composite material for a washing machine. The polypropylene composite material comprises the following ingredients in parts by weight: 50 to 55 parts of polypropylene, 30 to 40 parts of dicumyl peroxide, 10 to 15 parts of talcum powder and 5 to 10 parts of antioxidants. The polypropylene composite material has the advantages that the flowing performance of the polypropylene is obviously improved; meanwhile, the bending elastic modulus of the polypropylene is also effectively improved; the influence of a blending system on the flux flowing speed is reduced; the excellent comprehensive mechanical performance and physical performance are realized.
Description
technical field [0001] The invention relates to the field of composite materials, in particular to a polypropylene composite material for washing machines. 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, the polypropylene materials currently on the market have poor fluidity and cannot meet the basic needs of the market. Contents of the invention [0003] The purpose of the present invention is to overcome the above problems in the prior art, provide a polypropylene composite mater...
