Abstract
The invention discloses a paper base friction material which is characterized in that the paper base friction material is prepared by the following raw materials in part by weight: 45-60 parts of asbestos-free composite mineral fiber, 15-30 parts of mixture of cork nitrile rubber friction plate abrasive dusts and fine tyre powder, 10-20 parts of organic silane coupling agent, 20-35 parts of modified phenolic resin, and 1-10 parts of aramid fiber. The comprehensive performances of the paper base friction material is remarkably improved, the static friction coefficient is between 0.18 to 0.21, the dynamic friction coefficient is between 0.15 to 0.172, the production cost is low, and the properties of heat resistance and wear resistance are better.
Description
Technical field
The invention belongs to a kind of wet type organic-type friction material, relate to a kind of asbestos-free paper friction material specifically.
Background technology
Paper friction material is a kind of in the wet type organic-type friction material; It has the excellent friction polishing machine in the wet friction environment for use of oil lubrication; Be that frictional coefficient is higher; Dynamic and static frictional coefficient ratio is big, and thermostability, oil-proofness and wearability and heat-resisting decline property etc. are good relatively, and work-ing life is longer.Therefore it has important position in the wet type organic-type friction material at present.
At present on the market paper friction material is of a great variety, and the patent of application is very many (for example application number is 99114959.9, the Chinese patent of 200910254463.X etc.) also, and they mostly use bamboo fibers or xylon to process, and are unfavorable for environmental protection, cost height.And the static friction coefficient of present most of friction materials is between 0.14-0.165, and between the kinetic friction coefficient 0.12-0.15, frictional coefficient is on the low side.In addition, why paper friction material has the excellent friction polishing machine, mainly is to depend on this material to have vesicular structure; But up to the present, most of paper friction material in use, regular meeting is because under the effect that runs up with repeated friction pressure; Friction temperature is raise rapidly; Cause resin and relevant organic decomposition in the friction material constituents, frictional coefficient is descended, the friction hypofunction; So that friction plate skids and produces higher temperature, friction plate carbonization or ablation, loses the ability of transmitting moment of torsion.Therefore further the frictional coefficient, resistance to elevated temperatures and wear-resisting, the endurance quality that improve paper-base friction wafer are that the insider needs the further problem of research.
Summary of the invention
In order to solve the problems of the technologies described above, the object of the present invention is to provide frictional coefficient higher, heat-resisting, wear resisting property is better, the paper friction material of environmental protection, low cost of manufacture.
The present invention seeks to realize like this: a kind of paper friction material; It is characterized in that: the following starting material by parts by weight are processed: no asbestos compound mineral fiber 45-60 part; Mixture 15-30 part of cork paracril friction plate mill dirt and fined tyre powder; Organo silane coupling agent 10-20 part, modified phenolic resins 20-35 part, aramid fiber 1-10 part.
Adopt technique scheme, preparation method of the present invention is identical with the traditional preparation process method.Wherein not having the asbestos compound mineral fiber is to carry out spinning and carry out surface treatment processing through the High Temperature Furnaces Heating Apparatus above 1000 ℃ with ores such as Irish touchstone, diabase, ls, rhombspars; Itself wear resistance and good heat resistance; Frictional coefficient is highly stable, and more environmental protection with respect to bamboo fibers or xylon, cost are low.
The dust that cork paracril friction plate mill dirt produces when being the grinding of cork paracril friction plate owing to pass through pyroprocessing, has the performance of Heat stability is good; The fined tyre powder can improve paper friction material void content, reduce the declining property of heat of friction materials.Fined tyre powder and cork paracril friction plate mill dirt are the utilization again of waste product, the low and environmental protection of cost.
Organo silane coupling agent can bond together friction materials on the one hand, improves thermotolerance, and paper-base friction wafer and liner plate that paper friction material is processed well combine.
The static friction coefficient of the paper friction material of the present invention preparation is at 0.18-0.21, and kinetic friction coefficient is 0.15-0.172, and production cost is low, environmental protection, heat-resisting, wear resisting property is better.
In technique scheme; In order to reach better heat-resisting, wear resistance; Said paper base material is processed by the following starting material of parts by weight: no asbestos compound mineral fiber 50-55 part, mixture 20-28 part of cork paracril friction plate mill dirt and fined tyre powder, organo silane coupling agent 15-18 part; Modified phenolic resins 25-30 part, aramid fiber 5-8 part.
As of the present invention preferred, the mass ratio of cork paracril friction plate mill dirt and fined tyre powder is 2-3 described in the mixture of said cork paracril friction plate mill dirt and fined tyre powder: 1.
Beneficial effect: the over-all properties of paper friction material of the present invention is improved significantly, and static friction coefficient is at 0.18-0.21, and kinetic friction coefficient is 0.15-0.172, and production cost is low, environmental protection, heat-resisting, wear resisting property is better.
Embodiment
Below in conjunction with embodiment the present invention is done further explanation:
In the above-described embodiments, wherein the weight ratio of the cork paracril friction plate of embodiment 1-2 mill dirt and fined tyre powder is 2: 1, and the cork paracril friction plate mill dirt among other each embodiment and the weight ratio of fined tyre powder are 3: 1.
With no asbestos deposit fibres and the aramid fiber shredding among the embodiment 1-5, remove static.Adopting traditional paper technology will not have asbestos deposit fibres, aramid fiber, cork paracril friction plate mill dirt and fined tyre powder adds water and pulls an oar; Having beaten the slurry back sizes mixing according to the density of slurry; Carry out papermaking with paper machine then, be washed into the scraps of paper by the specifications and models hair after the papermaking.Modified phenolic resins is dissolved in the organo silane coupling agent; The scraps of paper that then hair are washed into type soak into and in organo silane coupling agent and double-modification phenolic resin solution, to soak into; The scraps of paper to after soaking into use oven for drying, carry out abrasive disc then, smartly dash, obtain the friction plate that this friction materials is processed with mould once shaped, curing.
The present invention is not limited to embodiment; Wherein the parts by weight of each component can also be got other value; Those of ordinary skill in the art is under enlightenment of the present invention; Under the prerequisite of aim of the present invention and claim, can make multiple similar expression, such conversion all falls into protection scope of the present invention.
