Description
Technical field
The present invention relates to polyethylene pipe, particularly a kind of is the ultrahigh molecular weight polyethylene abrasion-proof pipe of main raw material with the polyvinyl resin with super-high molecular weight.
Background technique
At present, the polyvinyl plastics pipeline of domestic production, majority is used for gas transmission, the water delivery engineering in fields such as combustion gas, chemical industry, tap water and power plant, aluminium manufacturer.And carry at the mine tailing in mines such as gold mine, copper mine, molybdenum ore, iron ore, the ore pulp under the coal mine is carried, the engineerings higher to pipe wear such as the lime-ash conveying of power plant, also most steel pipes that use.Tool wear-resisting property is preferably only starched to fine sand in common superhigh molecular weight polyethylene pipe road, but hardness is low, and is easily sagging, and delineation is afraid of in easily creep, can't satisfy lump material and carry, thereby use also incompatible in these higher engineerings of wearing and tearing.
Summary of the invention
Technical problem to be solved by this invention provides a kind of ultrahigh molecular weight polyethylene abrasion-proof pipe, and combination property especially wear-resisting property improves greatly, thereby is implemented in wear-resistant aspect to mould the breakthrough of Dai Gang.
Ultrahigh molecular weight polyethylene abrasion-proof pipe of the present invention, it is characterized in that in mass percent raw material comprises polyvinyl resin with super-high molecular weight 70%-90%, glass fibre or glass microballoon 3%-20%, silane coupling agent 0.1～1%, graphite 0.5%-3% and Tissuemat E 1%-7%.
Can also comprise acicular wollastonite 5%-20% according to usage requirement in the above-mentioned raw materials.
The present invention is a reinforcing material with acicular wollastonite, glass fibre (or glass microballoon), and is composite modified to the polyvinyl resin with super-high molecular weight blend, is solid lubricant with graphite, Tissuemat E, is that phase solvent carries out scientific matching with the silane coupling agent.Finished product tubing and common superelevation tubing with this formulation are made mortar abrasion comparative trial, and goods wear resistance, anti-ruled area double, and hardness improves 30%, and dimensional stability also is greatly improved.
Ultra-high molecular weight polyethylene (UHMW-PE) is a kind of model engineering plastic, and the relative molecular mass scope is greater than 1,000,000 oxygen units (it is better to do experimental performance with relative molecular mass 150-350 ten thousand oxygen units), and density is 0.935 g/cm
3Acicular wollastonite (CaSiO
3) have excellent abrasive resistance, reinforcement, be a kind of natural lily inorganic short fibre reinforcing material, be the metasilicate mineral of calcium, granularity 40-1250 order, slenderness ratio: 10: 1---20: 1, density 2.8-3.1g/cm
