Description
Technical field:
The invention belongs to friction material, relate in particular to a kind of car disk-type braking gland.
Background technique:
Brake lining belongs to one of critical material in automotive industry, and its quality not only influences rideability but also concerning driver and conductor's life safety.Therefore require used brake lining material must possess good heat resistanceheat resistant decline performance, stable friction factor at high temperature, braking process does not have noise, and having enough intensity and antithesis has good coupling and does not damage dual face.Moderate and the performance such as little of wearing and tearing of friction factor.Since the automobile invention, people are in order to pursue above-mentioned performance, and the research of brake material fails to stop always, constantly replace last generation product with brake material safer, more comfortable, more excellent in performance.
Traditional automobile brake lining plate adopts asbestos as reinforcing material, and this material can not adapt to the high-speed of automobile running.Especially confirmed as after the carcinogenic substance by medical circle, it is restricted in application facet.In industrialized country, the development that replaces asbestos friction material was just extensively carried out as far back as the beginning of the sixties, and asbestos-free friction material uses maximum asbestos substituents to be Steel Fibre at present.Yet the shortcoming of Steel Fibre is can produce corrosion under hygrothermal environment, and the easy damaged antithesis in use easily produces brake noise.People use mixed fibre (two or more fiber) to replace it again at the beginning of the eighties, have overcome the above-mentioned shortcoming that simple use Steel Fibre strengthens friction material.
Aspect tackiness agent, usually the tackiness agent that the material that creates friction uses is phenolic resin, and the product that adopts this resin to make exists hardness height, defectives such as fragility and poor heat resistance, therefore pliability, heat resistance and the intensity of people in order to improve this resin has been carried out the modification processing again to it.Phenol-formaldehyde resin modified commonly used at present has: cashew nut shell phenol-formaldehyde resin modified, melamine one cashew nut shell phenol-formaldehyde resin modified, nbr modified phenolic resins, epoxy modified phenolic resin etc.Process is to STUDY ON THE MODIFICATION OF PENOLIC RESIN, and product properties increases, but can not adapt to present requirement to Properties of Friction Materials.
Chinese patent 95108742.8 provides a kind of carbon-fiber-reinforced disk-type braking gland of automobile, and it contains charcoal fiber 5-15wt%, glass fibre 15-20wt%, and Steel Fibre 0-5wt%, tackiness agent 8-20wt%, frictional behaviour is adjusted agent 42-53wt%.The decomposition temperature of described tackiness agent is more than 500 ℃, thereby overcome the heat fade phenomenon of goods about 300 ℃, owing to adopted composite fiber, replaced single steel fiber or carbon fiber, make product of the present invention promptly keep the advantage of product former, reduced cost again.And low briquetting pressure has reduced the hardness of goods, has improved the porosity ratio of goods, thereby has reduced the noise of goods in braking process.Yet doing the disadvantage of bringing like this is the wear-resisting property variation that makes goods.
Summary of the invention:
It is low to the purpose of this invention is to provide a kind of hardness, and good disk-type braking gland of automobile of wear-resisting property and preparation method thereof.
Disk-type braking gland of automobile each component weight percent content of the present invention is:
Charcoal fiber 0-16 Steel Fibre 5-25
Organic fiber 0.5-8 mineral fibre 3-20
Frictional behaviour is adjusted agent 37-60 copna resin 4-16
Phenolic resin 2-8
Wherein: organic fiber is aramid fibre, raylande, oxidized fibre;
Mineral fibre is ceramic fiber, wollastonite fibre, sepiolite fibre.
The component that frictional behaviour is adjusted agent is:
Plumbago 4-16wt% petroleum coke powder 0-11wt% aluminium powder 0-11wt%
Iron powder 0-11wt% brass cream 4.5-11wt% CaCO
3Powder 0-9wt%
Silica flour 0-3wt% Cab-O-sil 0-6wt% cashew nut shell friction powder 0-6wt%
BaSO
4Powder 0-11wt% carbon black 0-1.5wt% Iron Ore Powder 0-8wt%
Acrylonitrile-butadiene rubber powder 0-3wt% alumina powder 0-3wt% white clay 0-10wt%
Copna resin is the thermosetting resin of a kind of condensation, many rings, multinuclear, aromatic hydrocarbon structure, and its heat resistance is better than phenolic resin.Can compare favourably with polyimide resin, and at high temperature the resistance to heat of (800 ℃) is better than polyimide, particularly it has with the compatibility of charcoal well, wear-resisting, and has characteristics such as certain elasticity.Copna resin can be a raw material with anthracene, pyrene, phenanthrene, coal-tar pitch, petroleum tar, with terephthalyl alcohol, to benzene benzyl chloride, bentaldehyde, phthalyl chloride, terephthalaldehyde, benzaldehyde, dimethyl terephthalyl alcohol etc. is crosslinking agent, and p-methyl benzenesulfonic acid is that catalyzer is polymerized.Concrete method for making is seen S.OTANT, International Symposium on Carbon1990,622-625 in detail.
The tackiness agent of making brake lining with this resin can improve heat resistance, the wear resistance of goods, reduces surface hardness.Adding quantity is in the scope of 4-16wt% in the prescription, and goods can be along with the increase of copna resin composition, and wear extent reduces, and surface hardness reduces, if content is very few, then product strength is low, also can not show the advantage of utilizing this resin simultaneously.If adding quantity is too much, the manufacturability of goods and correlated performance variation, the also corresponding increase of cost of product simultaneously.
The phenolic resinoid that adds 2～8wt% in prescription can improve the adhesive property of copna resin, so both can make goods keep certain intensity, can reduce the weight percent content of copna resin in the prescription again, because of copna resin more expensive on price than phenolic resinoid, do like this and can reduce the goods cost, and can improve its technology capability.
The present invention has adopted dry process, is about to material weighing by a certain percentage, mixing, stirring, be dried again after evenly mixing, cold moudling, hot-forming, heat treatment, machining, polishing is sprayed paint, and plays trade mark, packing afterwards product.
The present invention compared with prior art has following advantage:
Itself certain elasticity is just arranged because copna resin solidifies the back, can not add or add less organic filler, the stable friction factor of its goods, thermal conductivity is moderate, noise free when braking, friction, not scratch dual face and long service life, liner hardness is low, and wear resistance is good.
