Problems solved by technology

This kind of composite material has high gloss and heat distortion temperature, but the material does not have anti-oil properties. At the same time, due to the large shrinkage rate of high-crystalline PP, the size of the parts is prone to be too small, which affects product assembly and appearance.

Abstract

The invention provides a reinforced greasy-dirt-resistant high-gloss polypropylene composite material and a preparation method thereof. The reinforced greasy-dirt-resistant high-gloss polypropylene composite material is prepared form the following components in parts by weight: 60-80 parts of PP resin, 10-15 parts of superfine precipitated barium sulfate, 6-10 parts of reinforced magnesium sulfate whiskers, 2-5 parts of fluoride, 0.2-0.4 part of an antioxidant, 0.1-0.3 part of a nucleating agent, 0.5-1 part of a lubricating agent and 0-3 parts of other auxiliaries. According to the reinforced greasy-dirt-resistant high-gloss polypropylene composite material prepared by the method disclosed by the invention, the surface polarity of the material is changed and the greasy dirt resistance of the material is improved; meanwhile, the composite material meets the European Union Regulation (EC) No.1935 / 2004 of related food contact materials, and has the characteristics of being high in gloss, low in after shrinkage, high in rigidity, and the like. The material is applied to a housing of a kitchen appliance, so that the surface of the kitchen appliance has capacity of resisting greasy dirt and self-cleaning capacity, and the self-cleaning anti-greasy-dirt environmental requirements of modern kitchen appliance are met.

Description

technical field [0001] The invention relates to the technical field of macromolecules, in particular to an anti-oil pollution reinforced high-gloss polypropylene composite material and a preparation method thereof. Background technique [0002] Polypropylene is a thermoplastic resin produced by the polymerization of propylene, usually a translucent, colorless solid, odorless and non-toxic. Due to its regular structure and high degree of crystallization, its melting point can be as high as 167°C. It has the advantages of heat resistance and corrosion resistance, so its products can be sterilized by steam; in addition, polypropylene has a low density and is the lightest general-purpose plastic. However, PP has poor low-temperature impact resistance, large molding shrinkage, and poor creep resistance of dimensional stability. [0003] With the acceleration of the pace of modern life and the increase in consumer demand, the types and quantities of small household appliances a...
