Description
Technical field
The present invention relates to a kind of brake facing, especially relate to a kind of friction material composition for ceramic brake.
Background technology
In the 20-80 age in 20th century, the use of asbestos organic friction material is quite extensive.After international medical oncology in 1972 can confirm that asbestos and vaporization at high temperature thing thereof belong to carcinogens, start the tide that one prohibits the use asbestos friction material in the world, and along with the raising of car speed, make braking product surface temperature up to 300-500 DEG C, asbestos friction material thermal conductivity and poor heat resistance, crystal water is lost at about 400 DEG C, when 550 DEG C, crystal water completely loses, substantially reinforced effects is lost, frictional property can be caused unstable after asbestos dehydration, working layer goes bad, wearing and tearing aggravation, there is obvious heat fading phenomenon, asbestos organic friction material has been not suitable with automotive industry and modern social development's demand, replaced by novel material gradually.Semi-metal and few metal brake material are the asbestos-free friction materials that China mainly applies.But there is following shortcoming in semi-metallic brake pad: 1, steel fiber gets rusty easily, after corrosion or occur adhesion antithesis or damage antithesis, friction plate intensity is reduced, wearing and tearing aggravation, stable friction factor variation; 2, semimetal friction material thermal conductivity is high, when friction temperature is higher than 300 DEG C, binding resin between friction materials and steel substrate is made to decompose on the one hand, in addition even there is peeling phenomenon because of its thermal stresses in temperature head, on the other hand a large amount of heat of friction is delivered to rapidly the hydraulic pressure force application mechanism of piston, causes the softening and braking of sealing-ring cross generating gasification and cause brake failure; Although 3, semimetal friction material eliminates the high frequency noise that asbestos friction material easily produces, easily produce the low frequency noise under low speed.The advantages such as the ceramic brake material researched and developed in recent years has long service life, non-corroding, frictional coefficient is high, noise is low, but the formulating of recipe of domestic published ceramic brake material is perfect not enough, generally the physicochemical properties such as friction materials density, hardness and intensity are also only limited to Friction Materials, the real effect of the structure that these materials a lot of are formed jointly is not also well grasped, therefore existing ceramic brake piece performance is stable not, a lot of brake facing is at high temperature or when braking continuously, and its frictional coefficient easily fails, easily occur locking or brake failure phenomenon.
Summary of the invention
The present invention mainly solves existing automobile brake sheet and gets rusty easily, and material heat transfer is high, unstable properties during high temperature, produces the technical problems such as low frequency noise during brake.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of friction material composition for ceramic brake, makes by weight percentage primarily of following component:
Mullite Ceramic Fibres 14-18%, glue spraying aluminum silicate fiber 10-13%, aramid pulp 10-12%, red copper fiber 8-9%, potassium titanate crystal whisker 8-10%, nano-sized iron oxide 3-5%, aluminium hydroxide 0.8-1%, barite 7-12%, potassium felspar sand 8-10%, chromite 3-5%, magnesium hydroxide 1-1.5%, zinc oxide 0.2-0.5%, graphite granule 7-11%, expanded graphite 6-9%, paracril 1-2%, cashew nut oil modified alkyd resin 6-10%.
In the present invention, Mullite Ceramic Fibres is a kind of fibrous light refractory materials, have lightweight, high temperature resistant, Heat stability is good, thermal conductivity are low, specific heat is little and the advantage such as mechanical resistant vibrations.
Glue spraying aluminum silicate fiber well can absorb the noise that friction materials sends because of braking: have good resistance to elevated temperatures, extremely low thermal conductivity, it invests friction material surface can effectively reduce the character of heat-fading and swelling property of touching other cryogenic materials in material, improves friction materials in the stability manufactured and in use procedure.
Aramid pulp has good mechanical property, excellent resistance toheat and stable chemical property, can replace the main raw that fibrous magnesium silicate is used as brake facing.
The advantages such as it is low that red copper fiber has hardness, and heat conductivility is excellent.When for friction materials, it can reduce wearing and tearing, stablizes frictional coefficient, improves heat dispersion; The red copper fiber simultaneously softened because drag friction is heated can replace the tackiness agent of partial ablation, infiltrates surface with flakey, improves braking ability.
Potassium titanate crystal whisker refers to that a class chemical formula is K
2onTiO
2or K
2ti
no
2n+1, miniature outward appearance is the inorganic macromolecule compound of needle-like crystal, its Mohs' hardness is 4, easily mixes with body material.Employ the brake facing of potassium titanate crystal whisker, in brake of motor-driven vehicle process, can make the frictional coefficient of brake facing that large change does not occur, especially in long-time brake process, the rising of brake-block temperature will be caused to cause inefficacy or " locking " of brake facing because of during brake, thus improve the safety performance in brake facing use procedure.
Nano-sized iron oxide can be used as and meets ceramic substrate, and aluminium hydroxide, as friction resistance material, adds the frictional coefficient of adjustable brake facing in friction materials.Its thermal expansivity is little, and chemical stability is high, can keep the friction stability of friction materials.
Barite main component is barium sulfate, its unreactiveness and good stability, and hardness is moderate, can be used as weighting agent.Chromite belongs to the oxide ore of chromium and iron, and hardness is very high, simultaneously also high temperature resistant fire-resistant, can be used as increasing and rub agent in brake facing.Potassium felspar sand is the aluminium silicate mineral of potassium, is a kind of well abrasive material.Magnesium hydroxide, aluminium hydroxide can be used for high-abrasive material, have high temperature resistant anti-flaming feature, can improve brake facing stability.Graphite granule has that proportion is little, high temperature resistant, the feature such as wear-resisting by force, can be used as the low friction compound of brake facing, reduces brake noise.Expanded graphite is a kind of splendid friction materials, and it has good plasticity-and snappiness, is used in friction materials and has effect that is high temperature resistant, adiabatic, lubrication, can reduce the heat fading of friction materials, stablize the frictional coefficient of friction materials.
Paracril is a kind of synthetic rubber, has excellent adhesive property, for making wear part.Cashew nut oil modified alkyd resin has the good processing characteristics of better snappiness and resistance to acids and bases compared with phenolic resin, heat resistanceheat resistant decline and restorability good, be binder product the most frequently used in friction materials.
In order to obtain excellent combination property, stable formula system, contriver, through a large amount of experiments, reasonably arranges in pairs or groups to Multiple components, guarantees that the advantage of each material is fully played in friction materials.As the reasonable selection of the fortifying fibres such as ceramic fiber, glue spraying aluminum silicate fiber, aramid pulp, constitute the base material of brake facing; The frictional property regulators such as nano-sized iron oxide, aluminium hydroxide, barite, graphite granule not only regulate disc surface hardness, frictional coefficient, also improve heat transfer property and processing characteristics.Said components well combines as excellent binding agent by paracril, cashew nut oil modified alkyd resin.The present invention substantially increases the work-ing life of friction materials, relative to existing ceramic brake, machinery during high temperature of the present invention and braking ability are better, and during brake, feel is more comfortable, and continuous brake safe performance improves greatly, noise is less and conform to the environmental requirement day by day improved completely.
