Abstract

The present invention is one kind of composite modified ultrahigh molecular weight polyethylene material and the process of making mine pipe with the material, and belongs to the field of polyethylene material modifying technology. The composite modified ultrahigh molecular weight polyethylene material consists of ultrahigh molecular weight polyethylene 100-400 weight portions, liquid crystal polymer material 10-20 weight portions, flexibilizer 15-30 weight portions, and modifier 0.5-1.5 weight portions. It has tensile strength over 28.5-32 MPa, shock strength over 150 KJ / sq m, elongation at break 420-470 % and other excellent performance. It may be applied in making various kinds of pipes for use in coal mine.

Description

technical field [0001] The invention belongs to the technical field of modification of polyethylene materials, and more specifically relates to a composite modified ultra-high molecular weight polyethylene material, and also relates to a method for making mining pipes with the above-mentioned material. Background technique [0002] Due to the high molecular weight characteristics of ultra-high molecular weight polyethylene (UHMW-PE), it has good wear resistance (low wear), chemical resistance, impact resistance, pressure resistance, frost resistance, heat preservation, and anti-scaling The incomparable excellent properties of ordinary polyethylene and other engineering plastics, such as resistance to stress cracking, self-lubrication and non-adhesion, are used in harsh environments such as coal mines, mines, chemicals, textiles, transportation, machinery, construction, electrical, etc. , medical, sports and other fields have been widely used. [0003] Taking pipes made of u...
