Reinforced polypropylene material and preparation method and application thereof

Abstract

The invention discloses a reinforced polypropylene material and a preparation method and application thereof. The reinforced polypropylene material comprises the following components in parts by weight: 20-80 parts of straight-chain polypropylene; 5-40 parts of long-chain branched polypropylene; 0.5-25 part of a compatilizer; 5-60 parts of reinforcing fibers; 1-20 parts of a fluorine compound; the prepared polypropylene material has high melt strength and good rigidity and heat resistance, and is mainly suitable for blow molding, plastic uptake and other occasions.

Description

technical field

[0001] The invention relates to the technical field of engineering plastics, in particular to a reinforced polypropylene material and its preparation method and application. Background technique

[0002] Polypropylene material is currently the most used polymer material. It has excellent processing properties and mechanical properties. It is widely used in daily life and industrial production fields, such as: agricultural film, wire and cable, communication, housing construction and aviation manufacturing. Wait.

[0003] At present, the polyolefin materials suitable for blow molding and blister use are basically pure HDPE or PP resins. These resins can be molded well, but they still need to be improved in terms of heat resistance and strength. In the industry, the high strength and high rigidity of glass fibers are usually used to improve product strength and heat resistance, but conventional glass fiber reinforced polypropylene materials have low melt stren...
