Abstract

The invention discloses a wearable ultrahigh molecular weight polyethylene tubular product and a preparation method thereof, belonging to a composite of macromolecular compounds, and comprising the following raw material components in parts by weight: 95-98 parts of ultrahigh molecular weight polyethylene with viscosity-average molecular weight of 2800,000-2850,000, 1.8-4.8 parts of polyethylene wax with molecular weight of 1,000-1,500, and 0.1-0.3 part of carbon black. The invention provides the wearable ultrahigh molecular weight polyethylene tubular with performances of corrosion resistance, anti-adhesion, compression resistance, impact resistance, high surface hardness, good abrasion resistance, high mechanical strength, high heat distortion temperature, convenient process, long service life and low manufacture cost, and a preparing method thereof with simple manufacturing process and low production cost. As the substitute of steel tubes, the invention meets the market requirements, overcomes the defects of poor performances of corrosion resistance, abrasion resistance and anti-adhesion in the prior steel tubes, and is widely applied to the transportation of wastewater, waste residue and corrosive medium in the industries such as metallurgy, electric power, paper-making, chemical industry, machine, petroleum and the like.

Description

technical field [0001] The invention is a wear-resistant ultra-high molecular weight polyethylene pipe and a manufacturing method thereof. The invention belongs to a composition of polymer compounds, in particular to a modified ultra-high molecular weight polyethylene pipe. Background technique [0002] With the rapid development of the economy, the demand for steel pipes increases rapidly. However, iron ore, the raw material for steel pipe production, is a non-renewable resource. Due to the excessive mining of iron ore, the shortage of resources has caused the price of steel pipes in the market to continue to rise. The development of steel pipe substitute products is urgently needed by the market. In addition, the steel pipe itself still has the defects of poor corrosion resistance, wear resistance and anti-adhesion performance, which need to be improved. [0003] Ultra-high molecular weight polyethylene (UHMWPE) pipes are wear-resistant, corrosion-resistant, chemically ...
