Abstract

The invention discloses a polypropylene filling master batch, which consists of the following raw materials in parts by weight: 12-20 parts of polypropylene, 1 part of stearic acid, 0.3 part of an antioxidant, 1 part of a coupling agent, 3-5 parts of paraffin, 100 parts of stone dust, 2-3 parts of polyethylene wax and 0.1 part of a brightening agent, and is prepared by the following steps of: mixing by using a high-temperature mixing machine for 15 minutes at the temperature of 130 DEG C; and extruding and granulating with a double-screw extruder. The polypropylene filling master batch has a reasonable formula, contributes to solving the problems of difficulty in dispersing an inorganic filler, easiness in dispersing and the like, has the advantages of easiness in dispersing and high efficiency, and plays a role in toughening and enhancing a polypropylene resin, improving size stability and increasing surface gloss.

Description

technical field [0001] The invention relates to a polypropylene filler masterbatch, which belongs to the field of materials. Background technique [0002] Polypropylene resin is currently one of the most widely used general-purpose plastics. The method of polypropylene modification is usually to fill with inorganic fillers during processing, such as talcum powder, calcium carbonate, and hollow glass microspheres. [0003] Calcium carbonate is the most widely used, most convenient and cheap filler in the plastic and rubber industry. Filling plastic products with calcium carbonate can reduce costs, save raw materials, and improve molding processing performance. Talc powder is a unique natural mineral with scales. structure, has many excellent physical and chemical properties, such as flexibility, whiteness, hydrophobicity, chemical inertness, etc., and the price of talc powder is also relatively cheap. It is widely used in the plastic processing industry; glass microspher...
