Abstract

The invention provides a high light, high black and high impact polypropylene special material and a preparation method thereof. The high light, high black and high impact polypropylene special material is composed of the following raw materials by weight: 80-90 parts of polypropylene resin, 10-20 parts of mineral filler, 0.1-0.5 part of a nucleating agent, 0.2-0.5 part of a dispersant, 0.2-0.4 part of an antioxidant, 1-4 parts of black masterbatch, and 0-1 part of other assistants. The high light, high black and high impact polypropylene special material provided by the invention adopts a special mixing process and preparation method, enhances the crystallinity of polypropylene material, and improves the dispersion of mineral filler. At the same time, because of high gloss, the composite material can replace ABS materials, reduce materials, and also meet the regulation (EC) No.1935 / 2004 of EU on food contact materials. The material can be used in kitchen appliance shells, endow the kitchen appliance surfaces with high gloss and high light, and improve the product appearances.

Description

technical field [0001] The invention relates to the technical field of polymers, in particular to a high-gloss, high-black, high-impact polypropylene special 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, polypropylene has poor low-temperature impact resistance, large molding shrinkage, and poor creep resistance in 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 are in...
