Description
Technical field
The present invention relates to friction materials technology fields.
Background technique
With the quickening and improvement of living standard of modern life rhythm, family saloon is more and more common, while people
The braking effect of automobile is also increasingly valued.Safety and driver comfort of the automobile under various road conditions directly test vapour
Vehicle braking ability, performance that this requires the brake blocks of automobile under high-speed and high-temperature braking condition is stable, low noise, and brake block
The direct acting factor of energy is exactly the friction material for producing brake block, and the performance of rubber powder plays decision again and makees in friction material
With.
The existing common rubber powder of friction material is that faint yellow acrylonitrile-butadiene rubber powder subtracts though can increase the elasticity of product
It is poor to wear away performance of making an uproar, it is at high cost.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of dedicated anti-attrition noise abatement rubber powder of friction material and its preparation sides
Method, preparation method is simple, anti-attrition noise abatement superior performance, and heat resistance improves.
In order to solve the above technical problems, the technical solution used in the present invention is:
A kind of dedicated anti-attrition noise abatement rubber powder of friction material, raw material includes following substance by weight: 10-30 parts of butadiene-styrene rubber,
5-20 parts of sulphur, 2-15 parts of promotor, 2-10 parts of magnesia, 15-40 parts of nanoscale coarse whiting, 5-20 parts of cotton fiber, complex mineral
1-10 parts of fiber.
Preferred raw material includes following substance by weight: 15-20 parts of butadiene-styrene rubber, 8-15 parts of sulphur, promotor 5-10
Part, 5-8 parts of magnesia, 20-30 parts of nanoscale coarse whiting, 8-10 parts of cotton fiber, 3-7 parts of compound mineral fiber.
Further preferred raw material includes following substance by weight: 18 parts of butadiene-styrene rubber, 10 parts of sulphur, promotor 8
Part, 7 parts of magnesia, 25 parts of nanoscale coarse whiting, 9 parts of cotton fiber, 5 parts of compound mineral fiber.
The preparation method of the dedicated anti-attrition noise abatement rubber powder of friction material, comprising the following steps: (1) proportionally weighed
Material is uniformly mixed by ingredient using batch mixer, and mixing time is 8 minutes；
(2) compounding agent is added in the material mixed in (1) and mixing, time 10-12 minute of mixing, temperature is carried out by mixer
It is 110-120 DEG C, pressure 0.6-0.8mpa；
(3) the good material of mixing in (2) being subjected to mill by open mill, mixing temperature is 120-150 DEG C, roll spacing 2-3mm,
It is granulated by pulverizer, sizing is then carried out by screening machine, is finally packed.
Compounding agent is liquid paraffin, and 5-8 parts of compounding agents are added in every 100 parts of raw materials.
Compound mineral fiber and cotton fiber are commercially available conventional products.
Sulphur effect: bonding improves heat resistance wearability.
Promotor effect: tensile strength, the elasticity of product are adjusted.
Magnesia effect: improving the compactness of material, and high temperature resistant reduces heat fading.
Coarse whiting effect: increasing product density, improves compression strength.
Cotton fiber effect: increasing product strength, can produce stomata, increases product comfort, lubrication.
Compound mineral fiber effect: dispersion performance is good, increases product strength.
Compound mineral fiber is the compound mineral fiber of the model 1035 of Jinzhou City Jia Shide fibrous material factory production.Its
His material is commercially available conventional products.
The preparation method of the dedicated anti-attrition noise abatement rubber powder of friction material, comprising the following steps: (1) according to the proportion mix raw material
It closes and uniformly (2) sieves mixed raw material addition compounding agent progress mixing (3) finished product material mill, granulation, packaging.
Compounding agent is liquid paraffin.
The present invention improves comprehensive performance using anti abrasive butadiene-styrene rubber and other compounding agents.Simultaneously we rubber not
It is made into the following powder of 40 mesh under sulfided state, there are adhesive properties in use, reduce resin usage amount.In product pressing process
With combining closely for resin, physical reactions not only occur, but also chemically react, are more evenly distributed, as flexible stereoscopic graticule
It deposits in the product, elasticity, toughness, impact property is more preferable.
Organic material played in friction material reduce noise the effects of, anti-attrition noise abatement rubber powder of the present invention on year-on-year basis other
Organic material temperature tolerance and fatigue resistance and service life all increase substantially.
Resin has irreplaceable role as the bonding agent of brake block, but the temperature tolerance of resin and decomposability determine
The key factors such as the service life of brake block, noise, anti-attrition noise abatement rubber powder be natural rubber binding resin and other heatproof materials
Material, while remaining the cementability of rubber, improves heat resistance, is effectively reduced resin and other materials in brake block
Decomposition.
Table 3 and table 4 are the numerical value of common nitrile rubber and anti-attrition noise abatement rubber powder of the present invention each parameter at different temperatures.
It can be seen that under the same test conditions by upper table data, rubber powder weight abrasion of the present invention is less than acrylonitrile-butadiene rubber powder.
Above-mentioned four tables data explanation can partially substitute resin using anti-attrition noise-reduction rubber powder, reduce production cost, replace
For rear friction material heating wash one's face and rinse one's mouth, coefficient of temperature drop, wear rate and weight abrasion etc. parameters it is basicly stable.
Steady, the opposite reduction of abrasion of retention coefficient.This product is except the wearability and heatproof for improving common acrylonitrile-butadiene rubber powder
Property outside, also with rubber flexibility and adhesive property.Played in friction material good anti-attrition, improve brake comfort,
Braking and the effect for reducing noise.
The anti-attrition noise-reduction rubber powder that practical application is added 8 parts in formula can add less 2-3 parts of resin, and completely may be used
The rubber-based products such as acrylonitrile-butadiene rubber powder need not be added.
The total amount of organic substance is reduced in friction material, and product heat resistance improves.
Anti-attrition noise-reduction rubber powder of the present invention can substitute acrylonitrile-butadiene rubber powder, produce friction material using rubber powder of the present invention
, friction material price per ton and uses high-grade rubber cheap 1000 yuan or so compared with the acrylonitrile-butadiene rubber powder for using low grade
Rubber powder can substitute the rubber powder of height grade compared to cheap 5000-6000 member, aspect of performance completely.
The beneficial effects of adopting the technical scheme are that anti-attrition noise abatement rubber powder, preparation method thereof letter of the present invention
Single, anti-attrition noise abatement superior performance, heat resistance improves, and being produced into for friction material can be effectively reduced using rubber powder of the present invention
This.
