Description
Technical field
The present invention relates to a kind of automobile brake sheet, especially relate to a kind of medium-to-high grade car and use ceramic brake pad with high performance.
Background technique
Automobile brake sheet early is an asbestos type brake block, is confirmed it is carcinogen by medical circle but people find asbestos now.Brake each time; Brake block will be dispersed into the asbestos fiber more than millions of in the air; The fiber of its needle-like is easy to get into lung and stops, and causes stimulation, finally can cause the generation of lung cancer; But except the factor of health risk aspect, asbestos type brake block also exists another major issue.Because asbestos are adiabatic; Its capacity of heat transmission is poor especially, uses rear brake that heat is piled up in brake block repeatedly, after the brake block heating; Its braking ability will change; Produce same friction and the braking force number of times that can more touch on the brake,, will cause brake failure if brake block reaches certain temperature.Raising along with Hyundai Motor industrial expansion and social enviroment protection consciousness; The automotive friction material has all been obtained great progress at aspects such as material, manufacturing process at present; The brake block that many novel asbestos-free friction materials are made has appearred; As be used for the ceramic brake of medium-to-high grade car, advantage such as just have long service life, non-corroding, friction factor is high, noise is low.But present medium-to-high grade car is with the also main dependence on import of ceramic mould brake block; Offshore company is regarded as trade secret with the prescription of ceramic brake; And the design of the prescription of domestic ceramic brake is perfect not enough; Friction Materials generally also is only limited to physicochemical properties such as friction material density, hardness and intensity, and much the real effect of the common structure that forms of these materials is not also well grasped, and therefore existing homemade ceramic brake performance is stable inadequately; A lot of brake blocks are when high temperature, and its friction factor is prone to fail, occur easily the locking or the phenomenon of dawdling.Even friction material occurs and expand serious quality problems such as friction surface crackle.
Summary of the invention
Technical problems such as the present invention solves existing ceramic brake high temperature friction unstable properties, and heat resistanceheat resistant decline performance is not high, and abrasion resistance properties is lower.
Above-mentioned technical problem of the present invention mainly is able to solve through following technical proposals: this ceramic brake is processed by following compositions in weight percentage:
Ceramic fiber 7-11%; Ceramic fiber 5-8%; Spray glue aluminum silicate fiber 6-9%; Aramid fibre 5-8%; Red copper fiber 7-10%; Modified grammite 6-9%; Baryte 7-12%; Chromite 4-8%; Nitrile butadiene rubber 1-2%; Iron oxide black 2-4%; Granular graphite 7-10%; Zine oxide 0.1-0.2%; Calcined petroleum coke 4-8.5%; Expanded graphite 1-3%; Boron bakelite resin 5-9%; Magnetite 3-5%; Heavy-burned magnesia 0.8-1.3%; Silicon carbide 0.8-1.5%; Barium sulfate crystal whisker 4-7.5%; Potassium titanate crystal whisker 0.3-0.5%; Alumina fibre 1-2.5%.
In the present invention, ceramic fiber is a kind of high pure, high tenacity, the low-down fiber of slag ball content.Its low thermal conductivity prevents Hen occur when braking the brake pipe and the ultra-high temperature brake fluid effects.The kind of ceramic fiber is a lot of at present; Produce better synergy for can be the time with the combination of other composition; Acquisition has superperformance, stay-in-grade brake block; The inventor is locked in following scope: SiO through a large amount of experiments with contained key component of ceramic fiber and proportioning (the white proportion by subtraction of weight) thereof
247-55%, Al

2O1-3%, surplus is micro-oxide.When adopting the ceramic fiber of mentioned component, ceramic fiber has high temperature resistant, and advantages such as good thermal stability after other material mixing, 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.
Ceramic fiber is a kind of fibrous light refractory material, has in light weight, high temperature resistant, good thermal stability, heat conductivity is low, specific heat is little and advantage such as anti-mechanical shock.Spray glue aluminum silicate fiber can well absorb the noise that friction material sends because of braking: having good temperature resistance can; Extremely low thermal conductivity; It invests friction material surface can effectively reduce the character of heat-fading and the expansibility of touching other cryogenic materials in the material, improved friction material make and using process in stability: aramid fibre has superhigh strength, high-modulus and high temperature resistant, acid-fast alkali-proof, premium properties such as in light weight.Red copper fiber and its surface also form the sawtooth of multiple shape, make that uniformity coefficient and bonding force that the copper fiber mixes with other materials are more cotton than copper, copper wire, and copper powder is stronger.Advantages such as the copper fiber also has heat absorption soon in addition, and distribute heat is fast, and is high temperature resistant.The acicular wollastonite fiber powder of high length-diameter ratio (slenderness ratio is greater than 15) has reinforcing, and shock resistance prevents effects such as friction surface crackle.
The high-quality that silicon carbide is increases the material that rubs, and its high-temperature behavior is stable especially, even under higher temperature, it can keep extraordinary friction factor, and a certain amount of silicon carbide component can effectively reduce the decline property of friction material high-temperature brake.
The crystalline flake graphite perfect crystalline, the thin and good toughness of sheet; Physical and chemical performance is excellent, has good temperature tolerance, self lubricity, conductivity, thermal shock resistance, performances such as corrosion resistance.
Characteristics such as the graphite granule carbon content is high, the porosity is high, hardness is low, and heat-conducting property is low.Be used for the heat fade that friction material can reduce friction material, stablize the friction factor of friction material.
Boron bakelite resin has the heat resistance more much better than common phenolic resin, instantaneous heat-resisting quantity, ablation resistance and mechanical property.
Potassium titanate crystal whisker has very high heat-resisting, heat-shielding performance and good wear resistance and greasy property, and good with other friction material compatibility.
Adopt the ceramic brake of the present invention's prescription to have lower density and remarkable wearability; Be particularly useful for middle and high shelves car; Compare external homology ceramic brake; The present invention makes the brake performance of car load in the process of running at high speed better except keeping the intrinsic high tenacity of ceramic brake, brake steadily, the advantage such as low noise, improved the whole friction factor of brake block more greatly.Simultaneously in the agents enhance overall braking quality, more avoided hindering the phenomenon of antithesis dish because of producing high braking force, and the noise performance is good, feel is comfortable during brake.
