Abstract

The invention discloses a boiling-resistant color-changing polypropylene composite material, which is prepared from the following raw materials in parts by weight: 47 to 90 parts of a polypropylene resin, 2 to 15 parts of an acrylonitrile-styrene copolymer, 2 to 10 parts of a compatilizer, 1 to 8 parts of a filler modifier, 5 to 20 parts of a filler, 0.2 to 1.0 part of an antioxidant, 0.2 to 1.0 part of a weather-resistant agent, 0.1 to 2.0 parts of a heat-resistant modifier and 0.5 to 2.0 parts of a lubricant. The invention also discloses a preparation method of the boiling-resistant color-changing polypropylene composite material. Compared with the existing polypropylene composite material, the polypropylene composite material disclosed by the invention has high boiling discoloration resistance, high hardness, high heat resistance and good gloss, can be widely applied to household appliance shell parts such as tableware, electric cookers, electric kettles, induction cookers and the like as daily necessities, and has a wide market application prospect.

Description

technical field [0001] The invention relates to the technical field of polypropylene materials, in particular to a boiling-resistant discoloration polypropylene composite material and a preparation method thereof. Background technique [0002] Polypropylene resin raw material is a cost-effective synthetic resin with wide application. Polypropylene material is a partially crystalline polymer with high strength, stiffness, hardness and heat resistance. Its melting point can reach above 165°C. It is non-toxic, Odorless, low density, excellent strength, stiffness, hardness, heat resistance, good electrical and insulating properties, and common acid and alkali organic solvents have little effect on it. [0003] At present, in order to reduce costs, many dinner plates, bowls, dishes, induction cookers, electric kettles, and rice cooker shells on the market are produced with polypropylene composite materials. Since the above-mentioned products are often in contact with hot water d...
