Abstract
The present invention provides a friction material containing no asbestos or metal for industrial use, and in particular relates to a manufacturing technology for industrial friction materials such as port machinery, crane machinery, and wind-power generator groups and so on. The potassium titanate is used as the main raw material; the glass fiber and cellulose fiber are used as the assistant materials; the cashew oil modified resin and nitrile modified resin are used together as bonding agent; the magnesium oxide, graphite and friction powder are used as friction-reducing agent; the alumina oxide and brown corundum are used as friction-increasing agent; the barium sulfate and barite are used as additive; the raw material are mixed according to a formula proportion and then blended; the friction component of best performances can be made after molding and heat treatment; the friction component is in particular suitable for port machinery, crane machinery, and wind-power generator groups and so on.
Description
Technical field
The invention belongs to the friction materials technical field, relate to a kind of industrial, by the crystal whisker of hexa potassium titanate enhanced, do not contain the friction materials of asbestos and metal, be specially adapted to make the brake component of harbour machinery, hoisting machinery, aerogenerator etc.
Background technology
In current industrial friction materials technology, most of fibrous magnesium silicate, steel fiber, glass fibre of adopting is as toughener.Adopt fibrous magnesium silicate as toughener, can obtain higher mechanical properties, but the asbestos dust serious environment pollution in manufacturing and braking procedure is detrimental to health, and is extensively forbidden in the world with lower cost; The employing steel fiber is that the quality of friction materials of toughener own is big, hardness is high, and quality is easy to generate low frequency noise greatly, and environment is caused noise pollution, and the hardness height injures antithesis easily, and the price height of steel fiber, should not apply on a large scale; The friction materials high-temperature behavior that simple employing glass fibre is a toughener is bad, wear rate is high, use properties is unstable, work-ing life is short.Have in recent years and adopt that needle-shaped wollastonite powder and pure aluminium silicate series fiber are cotton to replace the technology of fibrous magnesium silicate (referring to the patent No.: 02116595.5 Chinese patents in 2002) for toughener, its Specifeca tion speeification frictional coefficient is 0.3-0.5, fluctuation range is big, the parameter lower limit is low, do not reach the performance perameter of asbestos friction material, and its material prescription and production technique are for motor vehicle brake and other small-sized friction materials design, and are not suitable for the industrial stopper that apparent size is big, thickness is thick.
Summary of the invention
Purpose of the present invention is exactly to be to provide a kind of stable performance, cheap, main performance index to surpass the product that relies on fibrous magnesium silicate to strengthen friction materials, healthy harmless, environmentally safe to human body, can suit industrial stopper large size, big thickness requirement, no asbestos, metal-free friction material.
Technical scheme of the present invention is: cashew nut oil modified resin and butyronitrile modified resin are also with being caking agent, based on crystal whisker of hexa potassium titanate, glass fibre and cellulosic fibre is auxilliary as toughener, magnesium oxide, graphite, attrition powder are as low friction compound, aluminum oxide, brown corundum are as increasing the agent that rubs, and barium sulfate, barite are that the additive configuration forms.The weight percent that its prescription is formed is: cashew nut oil modified resin 8-15%, butyronitrile modified resin 8-10%, crystal whisker of hexa potassium titanate 10-40%, glass fibre 5-10%, cellulosic fibre 1-3%, magnesium oxide 1-2%, graphite 7-15%, friction powder 3-5%, aluminum oxide 0.5-1%, palm fibre corundum 2-3%, barium sulfate 0.5-1%, barite 3-5%.
The manufacturing process of this friction materials is fairly simple, mix after various raw materials are taken by weighing by formula rate and stirred 30-50 minute, then material is put into mould, under 120-140 ℃ of temperature with the pressure of 40-50Mpa, according to 120-180 second/millimeter control dwell time compression molding, after the depanning under 130-150 ℃ of temperature thermal treatment 6-8 hour, goods reached optimum performance.
It is main as toughener selecting crystal whisker of hexa potassium titanate in the present invention's prescription for use, crystal whisker of hexa potassium titanate is a kind of needle-like crystal, have good mechanical performance and physicals, and very high heat-resisting (1200 ℃ of softening temperatures), heat-proof quality and excellent infrared reflection performance.Thermal expansivity and plastics are suitable, have good wear resistance, oilness and high temperature sound absorbing, because its staple length is shorter, make its easier shredding in the dry mixed process, even with the common batch mixing of multiple fiber the time, also have remarkable dispersing property, have the biodegradability of height.Crystal whisker of hexa potassium titanate can with cashew nut oil modified resin and butyronitrile modified resin good binding, thereby under abominable brake condition, also can have extraordinary strength characteristics, improved the wearing and tearing of material, reduce noise and vibrations.Though the crystal whisker of hexa potassium titanate cost is slightly high, along with its superiority on the solution environmental issue of raising of product performance, added value of product is higher, is with a wide range of applications in industrial stopper fields such as harbour machinery, hoisting machinery, aerogenerators.
Embodiment
The weight percent that prescription is formed: cashew nut oil modified resin 15%, butyronitrile modified resin 10%, crystal whisker of hexa potassium titanate 35%, glass fibre 8%, cellulosic fibre 3%, magnesium oxide 2%, graphite 13%, friction powder 5%, aluminum oxide 1%, brown corundum 3%, barium sulfate 1%, barite 4%.
Manufacturing process: mix after various raw materials are taken by weighing by above-mentioned formula rate and stirred 45 minutes, then material is put into mould, under 135 ℃ of temperature with the pressure of 45Mpa, according to control dwell time compression molding in 170 seconds/millimeter, thermal treatment 7 hours under 135 ℃ of temperature after the depanning, goods reach optimum performance.
