Abstract
The invention discloses a polymer composite material for manufacturing a roller, which is prepared from the following materials in percentage by weight: 35-45% of nylon 6 (PA6), 20-35% of ceramic powder, 15-25% of glass fiber and 3-8% of composite solid lubricant, wherein the composite solid lubricant is prepared by mixing supramoly, graphite and other solid lubricant according to a weight ratio of 1:1-2. After being mixed according to the ratio, all the materials are mixed and extruded by a screw extruder, are subject to water-cooling pelleting, and are processed by an injection molding machine to be molded into a belt roller. The belt conveyor roller made of the composite material combines performance characteristics of polymer materials and ceramic materials, has the advantages of high strength, abrasion resistance, antistatic performance, flame retardance, corrosion prevention, light weight, low noise for high-speed operation, long service life, low price and the like, and can be widely used in industries or fields of smelting, mining, thermal power generation and the like.
Description
Technical field
The present invention relates to a kind of matrix material that carrying roller is used of making, especially a kind ofly make the polymer-ceramic composite material that carrying roller is used.
Background technology
Endless belt conveyor is a kind of conveying machinery equipment commonly used on the engineering, and it is simple in structure, cheap, and easy to maintenance, can realize the requirement of the convey materials of different distance, is widely used in the engineering reality such as smelting, mine, fuel-burning power plant.Effect at the endless belt conveyor middle idler roller is support belt and weight, reduces refacing and operating swing of conveying belt, to guarantee that conveying belt along the pre-determined direction smooth running, is one of important part in the transfer roller.In current techniques, because carrying roller material and structure imperfection, in the carrying roller use, because the erosion of water, dust and various objectionable impurities (acid, alkali, salt etc.) causes corrosion to part, causes sealing effectiveness not keep for a long time, particularly not wear-resisting, cause the carrying roller lost of life.The carrying roller that traditional weldless steel tube is made, in use be easy to because very easily producing static in chemical corrosion and the operational process, thereby limited its use, the mean lifetime of country's steel carrying roller is received the order far below design, generally below 8000h, and the carrying roller that the wear-resistant ceramic on the market is made, though have wear-resisting, acid and alkali-resistance, advantage such as anti-oxidant, but it is heavy to have quality, poor toughness, shortcoming such as property is crisp, the plastic conveyer roller that single macromolecular material is made, it is compared with the steel carrying roller, light except having quality, cost is low, corrosion-resistant, shock resistance, the high-speed cruising noise is low to be waited outside the remarkable advantage, but plastic conveyer roller heatproof, weather changes, performance such as wear-resisting is not as pottery, and it is short to we can say that therefore carrying roller ubiquity that these materials are made the life-span, defectives such as maintenance is big are restricting the development of endless belt conveyor to a certain extent.
Summary of the invention
The purpose of this invention is to provide a kind of polymer---ceramic composite, the carrying roller made from this matrix material, it all has a performance characteristics of macromolecular material and stupalith, possesses high strength, wear-resistant, antistatic, fire-retardant, protection against corrosion, in light weight, advantage such as the high-speed cruising noise is low, long service life, price are low.
To achieve these goals, the technical solution used in the present invention is:
A kind of polymer---ceramic composite, its prescription is: nylon, ceramics powder, glass fibre, compounded lubricant.
The proportioning of material therefor is (weight percent): nylon 6 (PA6): 35%～45%; Ceramics powder: 30%～35%; Glass fibre: 15%～25%; Compounded lubricant: 3%～8%, wherein compounded lubricant by molybdenumdisulphide and graphite by 1: the proportioning of (1～2) weight mixes.
It is body material that the present invention adopts nylon 6 (PA6), nylon is a class hemicrystalline, the thermoplastic macromolecule material with repetition amide structure, the nylon 6 (PA6) that is widely used in the polyamide resin of engineering materials has excellent mechanical intensity, toughness, oil resistant solvent resistance, anti-attrition antiwear characteristics, wear-resisting material abrasion characteristic excellence particularly, when under the case conditions that foreign matter is sneaked into or the mating material surfaceness is bigger is arranged, using, fastness to wear obviously is better than other resin materials, and intensity height, good toughness.Ceramics powder adds prescription as a kind of filler, it selects the alumina-ceramic super-fine powder for use, the ceramics powder filler can lower the wearing and tearing of polymkeric substance, because filler has increased the cohesiveness between transfer film and the wearing and tearing antithesis, the ceramics powder of suitable amounts not only can strengthen polymkeric substance, can improve simultaneously resistance toheat, dimensional stability, swelling property, hardness and the shrinkability etc. of polymkeric substance, can also reduce cost simultaneously.Glass fibre adds prescription as a kind of toughener, because glass fibre has very high strength and stiffness and good thermal conductivity, can improve the friction and wear characteristic of polymkeric substance, and improve its mechanical property and work-ing life.The compounded lubricant that the present invention uses is formed by solid lubricants such as molybdenumdisulphide, graphite are compound, in order to improve the body material friction and wear behavior, selection to oilness is most important, compound compounded lubricant and polymkeric substance, the solid compounded lubricant shifts the engaging friction interface and lubricate gradually in friction process, can improve the performances such as friction of polymer composites like this---reduce frictional coefficient, improve wear resistance.Why the solid compounded lubricant has the anti-friction antifriction function is the transfer film that has formed low shearing resistance because of frictional interface in transmission process.
Embodiment
Be described in further detail below in conjunction with the specific embodiment of the present invention of embodiment.
A kind of polymer---ceramic composite, its prescription is (weight percent): nylon 6 (PA6): 45%; Ceramics powder: 30%; Glass fibre: 20%; Compounded lubricant: 5%.Wherein nylon 6 (PA6) is body material; Ceramics powder is the micro mist of alumina-ceramic through pulverizing, and plays filling effect; Glass fibre is a kind of toughener; Compounded lubricant is by molybdenumdisulphide, the graphite modifying function that mixes of 1: 1 proportioning by weight.
After matrix material of the present invention mixed by proportioning, mixing extruding and the water-cooled granulation was machined to belt roller through injection molding again in screw extrusion press.
Claims (1)
1. a polymer---ceramic composite is characterized in that: its formulation weight per-cent is: nylon 6 (PA6): 35%～45%; Ceramics powder: 30%～35%; Glass fibre: 15%～25%; Compounded lubricant: 3%～8%; Described
Compounded lubricant is by molybdenumdisulphide, graphite by weight 1: the mixed of (1～2) is formed.
