Abstract
The present invention discloses a high-temp. non-asbestos friction material, and its mixing ratio is as follows: 8-28% of butyronitrile-modified phenolic resin, 3-20% of steel fibre, 3-27% of iron powder, 4-10% of frictional behaviour regulating agent, 3-5% of wollastonite, 8-30% of graphite, 2-7% of pottery clay powder, 3-9% of zircon, 4-6% of baddeleyite, 7-10% of feldspar powder, 7-9% of elastomeric friction powder and 1-2% of magnesium oxide. It has the advantages of good wearing resistance, resistance to heat attenuation, small even wear and stable friction coefficient.
Description
The present invention relates to a kind of friction materials, the especially a kind of used brake of maker motor-car, rig, a kind of high temperature resistant no asbestos friction materials of piece sheet of being used for.
Well-known with the made finished product of the friction materials that contains the asbestos composition, though have resistant to elevated temperatures advantage, but in use the dusty gas that is produced has very big pollution to physical environment, therefore now comparatively there be not the asbestos composition in its material composition that is mixed of popular friction materials goods, yet, present known friction materials, in particular for the maker motor-car, the brake of rig band-type brake, the material that the piece sheet is used, its frictional coefficient, the performance characteristics that the variation that wear rate and shear rate are all faced value because of temperature of living in makes it material is affected and causes the made finished product job insecurity of material, reliability is also poor.
The objective of the invention is to solve above-mentioned deficiency and a kind of resistant to elevated temperatures no asbestos friction materials is provided, face in the value step requirement in different temperature the product performance characteristics to satisfy by the made product of this material.
Task of the present invention is realized by following method:
Nbr modified phenolic resins: 8-28%; Drill rod dimension: 3-20%; Iron powder: 3-27%; Frictional property regulator: 4-10%; Wollastonite: 3-5%; Graphite: 8-30%; Potter's clay powder: 2-7%; Zircon: 3-9%; Dou zircon: 4-6%; Feldspar Powder: 7-10%; Elastomerics friction powder: 7-9%; Magnesium oxide: 1-2%.The oven for drying that drops into after the kneading of input kneader behind thorough mixing in above ratio preparation drops into the last finished product that forms of pulverizer pulverizing again.
The finished material of being finished by said ratio technical process again has good wear resistance, heat-resisting decay, and the antithesis wearing and tearing are little, advantages such as stable friction factor.
Proportioning of the present invention and embodiment are detailed by following content:
Nbr modified phenolic resins: 8-28%; Drill rod dimension: 3-20%; Iron powder: 3-27%; Frictional property regulator: 4-10%; Wollastonite: 3-5%; Graphite: 8-30%; Potter's clay powder: 2-7%; Zircon: 3-9%; Dou zircon: 4-6%; Feldspar Powder: 7-10%; Elastomerics friction powder: 7-9%; Magnesium oxide: 1-2%.The material product of handling back formation through technical process according to this proportioning is with reference to GB5763-86, GB257-86, and JISD4411-75 and international standard FF level have mirror as follows than parameter:
