Ultra-high molecular weight polyethylene tube and production technique thereof

Abstract

The invention relates to an ultra-high molecular weight polyethylene tube which is characterized by comprising the following components in parts by weight: 85-120 parts of ultra-high molecular weight polyethylene, 5-20 parts of polypropylene, 2-15 parts of polyethylene and 0.2-4 parts of nucleating agent. The tube can also comprise graphite and plastic assistants. The polypropylene and polyethylene are blended to modify the ultra-high molecular weight polyethylene, so the prepared ultra-high molecular weight polyethylene tube not only has the properties of the raw material, but also has the good characteristics of polyethylene and polypropylene; and thus, the ultra-high molecular weight polyethylene tube is easy to process, and has the advantages of favorable plastifying effect and high production efficiency.

Description

technical field [0001] The invention relates to a pipe material, in particular to an ultra-high molecular weight polyethylene pipe material and a production process thereof, and belongs to the technical field of research on the pipe material process formula. Background technique [0002] With the advancement of science and technology and the development of society, the application of polymer materials is becoming more and more extensive. With the guidance of national policies, plastic pipes are more and more widely used. UHMWPE pipes have excellent performance and are known as the "King of Plastics". Therefore, they are widely used in various fields. Ultra-high molecular weight polyethylene (UHMW-PE) has an average molecular weight of about 350,000 to 8 million. Because of its high molecular weight, it has excellent impact resistance, wear resistance, self-lubrication, and chemical corrosion resistance that other plastics cannot match. Moreover, ultra-high molecular weight ...
