Abstract
The invention discloses a clutch facing prepared by winding polyacrylonitrile fiber, relates to friction materials in an automobile transmission mechanism, and in particular relates to a clutch facing containing no glass fiber and without asbestos winding. The invention provides a glass fiber non-containing asbestos-free novel skeleton material clutch facing, aiming to solve the problems of poor abrasive resistance of the clutch facing made from skeleton materials used currently, stimulation to skin of human bodies in the production process, and the like. The clutch facing comprises the following ingredients in parts by weight: 18-28 parts of skeleton fiber, 10-20 parts of phenolic resin, 10-20 parts of styrene-butadiene rubber, 12-20 parts of barite; 5-15 parts of graphite and 15-35 parts of function fillers, wherein the skeleton fiber is composite fiber made from plyacrylonitrile fiber and aramid fiber, the content of the plyacrylonitrile fiber is not less than 95%, and the content of the aramid fiber has important influence on the quality of the product provided by the invention. The heat resistance of the clutch facing prepared by winding polyacrylonitrile fiber provided by the invention is good, and can reach more than 350 DEG C, namely the high-temperature friction coefficient is stable, and the abrasion rate is low.
Description
Technical field
The present invention relates to used friction material in the vehicle transmission mechanism, being specifically related to not contain glass fibre does not have the asbestos winding clutch facing.
Background technique
At present, the non-asbestos yarn of framework material that common non-asbestos winding form clutch plate adopts in producing on the market, mainly be composite fiber, bag core glass line, non-asbestos glass line etc. based on the glass fibre of various modifications, friction factor is little and unstable and wear rate is big during clutch surface high temperature that this framework material is made, its wear resistance can not satisfy the usability requirement of modern automotive to used clutch friction plate fully, as when requiring the clutch friction plate serviceability temperature to reach 350 ℃ wear rate less than 0.70.In addition, the dust that produces in the course of working of glass fibre or its complex yarn produces human body skin to stimulate, and causes the phenomenon of pruitus and skin lesion, brings adverse effect for workers ' health and production.
Summary of the invention
The objective of the invention is to make in order to solve present used framework material that the wear resistance that the automobile-use clutch friction plate exists is relatively poor, human body skin produced in the production process problem such as stimulation, provide a kind of glass fibre that do not contain not have the novel framework material polyacrylonitril fiber of asbestos winding clutch facing.The prescription of polyacrylonitril fiber winding clutch facing of the present invention is as follows: (calculating according to the mass fraction)
It is characterized in that the composite fiber that fibrous skeleton is made with polyacrylonitril fiber and aramid fibre, polyacrylonitril fiber content must not be less than 95%, and the consumption of aramid fibre also has material impact to the quality of clutch surface of the present invention.
Polyacrylonitril fiber winding clutch facing of the present invention is tested on the constant speed test machine, and friction factor is 0.25～0.35 in the time of 350 ℃, wear rate≤0.3 * 10
-7Cm
3/ Nm has solved existing clutch surface relatively poor problem of wear resistance when high temperature.Mainly be owing to use new fibrous skeleton to replace glass fibre and composite fiber thereof, improved the high-temperature wearable damage property of clutch surface greatly.The present invention has good heat resistance can be up to more than 350 ℃, the characteristics that promptly high temperature friction coefficient is stable, wear rate is low, and the relevant production process of product has no stimulation to human body.
Embodiment
The optimization formula embodiment of this polyacrylonitril fiber winding clutch facing (following umber is mass fraction):
Produce with conventional method by the following formula prescription and to get final product.Being about to rubber refining and becoming film, is that solvent is made rubber slurry using, impregnated skeleton fibre threads again with gasoline or solvent wet goods again, and handles by series of process such as twining, hot-forming after super-dry again, makes the automobile-use clutch friction plate.
Claims (2)
1. the polyacrylonitril fiber winding clutch facing is characterized in that described clutch surface slice prescription by mass percent is: fibrous skeleton 18～28, phenolic resin 10～20, styrene butadiene rubber 10～20, barite 12～20, graphite 5～15, functional stuffing 15～35.
2. polyacrylonitril fiber winding clutch facing according to claim 1, it is characterized in that fibrous skeleton is the composite fiber made from polyacrylonitril fiber and aramid fibre, polyacrylonitril fiber content must not be less than 95%, and the consumption of aramid fibre also has material impact to the quality of clutch surface of the present invention.
