Abstract
An organic fibre brake pad with satisfactory radiating effect comprises the following components according to weight percentages: 5-9% of cashew nut oil friction powder, 5-7% of tyre powder, 4-8% of chromite, 4-7% of calcined petroleum coke, 3-7% of crystalline flake graphite, 4-7% of squama-shaped aluminium powder, 4-7% of ceramic fibre, 4-7% of antimony sulphide, 4-7% of brass fibre, 3-5% of glued alumino-silicate fibre, 9-12% of vermiculite powder, 10-15% of phenolic resin, 7-10% of barite, 0.5-1% of polyacrylonitrile fibre, 3-6% of wood pulp fibre, 3-6% of viscose fibre and 3-6% of bamboocarbon fibre; the invention is especially applicable to a rear brake with comparatively high brake comfort requirement of a family car and the like, after the brake pad is used, the car brake is sensitive, the braking is stable without brake scream, comfort performance is good, and the brake drum or brake disc has no damage and ash falling in long-term use.
Description
Technical field
The present invention relates to a kind of automobile brake sheet, especially relate to the good organic fibre brake pad of a kind of thermal diffusivity.
Background technique
The semi-metallic brake pad that occurs in the market or the performance of micro-metal brake pad are not fine, under the moisture effect corrosion serious, noise is higher during brake, and brake squeal is arranged; Larger to the damage of brake drum or brake disc, for a long time not easy locking of apply the brakes system etc.And the dust that most semimetals or micro-metal brake pad in use produce easily, these dusts are adsorbed on the wheel hub, owing to be difficult to clean, are subjected to its Long-term Effect, easily cause the wheel hub corrosion.Although organic fibre brake pad can address the above problem to a certain extent, existing organic fibre brake pad heat radiation is bad, and long-term use causes brake block to lose efficacy easily.
Summary of the invention
The present invention solves existing semimetal or the easy corrosion of micro-metal brake pad, and noise is higher during brake, and is larger to brake drum or brake disc damage, and the technical problems such as ash easily fall.
Simultaneously, the present invention has also solved the bad technical problem of existing organic brake block heat radiation.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: this brake block is made by following compositions in weight percentage:
Cashew nut oil friction powder 5-9%, tyre talc 5-7%, chromite 4-8%, calcined petroleum coke 4-7%, crystalline flake graphite 3-7%, scale aluminium powder 4-7%, ceramic fiber 4-7%, antimony sulphide 4-7%, brass fiber 4-7%, glue spraying aluminum silicate fiber 3-5%, vermiculite power (20-40 order) 9-12%, phenolic resin 10-15%, barite (600 order) 7-10%, polyacrylonitril fiber 0.5-1%, wood pulp fibre 3-6%, viscose 3-6%, bamboo carbon fibre 3-6%.
In the present invention, cashew nut oil friction powder is to be processed by cashew nut shell oil, non-volatilely in the use go out any harmful matter, it is a kind of novel environment friendly product, after brake block mixes an amount of friction powder, more than 300 ℃ during hot operation, the brake block stable friction factor, heat expansion is minimum, can not produce " locking " phenomenon during brake.And it is strong that brake block has wear resistance, good toughness, the advantage such as noise is low, and is safe and reliable.
Tyre talc claims again the rubber break flour, is the tire glue face of junked tire, removes curtain radial, and pulverizing processes.It is used for friction material as elastic filler, plays to increase to wear away the effect of making an uproar.
Chromite is used for friction material, can adjust friction.Barite can be stablized frictional strength and the durability of friction material.
Add certain calcining coke and graphite than row in the friction material and can make friction material have perfect combination property, be conducive to prevent the metal adhesion, improve frictional behaviour.In addition, the empty rate of the gas of coke is higher, has improved the friction factor of friction material, has reduced brake noise, the heat fade of friction material when having alleviated high temperature.
It is that Raw material processing forms that the scale aluminium powder adopts the high wrought aluminium of purity, and the fusing energy of metallic aluminium has absorbed a large amount of heat energy in the friction process, has played the effect of heat radiation; And do not hinder dish, can prolong the working life of brake system.In addition, aluminium is very even in the surface distributed of friction material, makes the surface aesthetic of friction material beautiful.
Ceramic fiber is a kind of high pure, high strength, the low-down fiber of slag ball content.The superhigh temperature that occurs when the pyroconductivity that its Hen is low can prevent from bringing to a halt is on the impact of Brake pipe and brake oil.The kind of ceramic fiber is a lot of at present, produce better synergy for can be with the combination of other composition the time, acquisition has superperformance, stay-in-grade brake block, the inventor is through a large amount of experiments, and the key component that ceramic fiber is included and proportioning (weight percentage) thereof are locked in following scope: SiO
247-55%, Al
2O
317-23%, TiO
21-2%, other components and ratio are preferably CaO6-12%, K
2O1.1-3%, MgO4-7%, Fe
2O
38-10%, Na
2O1.5-3%, surplus is the micro amount of oxygen compound.When adopting the ceramic fiber of mentioned component, ceramic fiber has high temperature resistant, and the advantages such as good thermal stability after other material mixes, can be learnt from other's strong points to offset one's weaknesses, synergy, thus the heat fade phenomenon of the sheet of reducing friction has guaranteed the high-quality of product.
Brass fiber has the advantages such as heat absorption is fast, and distribute heat is fast, and is high temperature resistant.It is the important high-abrasive material of brake block.
Polyacrylonitril fiber has high-tensile, and is high temperature resistant, and adsorptivity is strong, the characteristics such as stable chemical nature.Viscose is used as the friction material reinforcing fiber, exchanges frictional behaviour and the porosity of whole timber material, prevents that the vitrifaction of some material is obvious.Wood pulp fibre can help various raw materials to be evenly distributed among the blending material, strengthens the effect that combination force between the various raw materials is born mesh skeleton in the brake block system well.Bamboo-carbon fibre is constructed fine and closely woven porous, and stronger adsorptivity is arranged, and adsorbable various pulverulent materials strengthen the friction material steadiness.And it is thin that its distinctive vesicular structure can make other fiberous material fully open, and pulverulent material mixes.As in the brake block course of working, clustering phenomena might appear in the fibers such as brass fiber, and friction surface hardness differs greatly like this, causes the not enough formation of braking moment noise, and the agglomerating phenomenon that bamboo-carbon fibre just in time can avoid the red copper fiber to occur.
The present invention has the characteristics such as friction factor height, high temperature resistance heat fade performance be good.The heat sink materials such as the scale aluminium powder that adds in the prescription simultaneously, brass fiber can make the present invention have extraordinary heat dispersion, thereby prolong the working life of product.It is rear brake to the higher car of braking comfort requirement that the present invention is particularly useful for such as family-sized car etc., and after using the present invention, braking automobile is sensitive, braking is steady, brakeless shriek, and comfort property is fine, and long-term the use, brake drum or brake disc not damaged, grey phenomenon falls.
