Abstract
The invention provides a manufacturing method of a friction material with a copper-free ceramic formula. The formula comprises the following raw materials in percent by weight: 5-15% of bonding agent, 20-30% of reinforcing material, 30-50% of friction performance adjusting agent and 20-30% of filler; the processing process comprises the following steps: all the raw materials required by the formula are put into a material mixing tank, and the mixed materials are stirred; after being discharged, the mixed materials are subjected to hot-pressing molding, the temperature of a mold is 160 DEG C, the molding pressure is 400kg/cm, and the pressure maintaining time is 10min; and the molded friction material can be used after grinding. The friction material has the advantages of good heat conductivity, no noise or falling ash and comfortable braking.
Description
Technical field
The present invention relates to a kind of method of manufacture of friction materials, especially a kind of automobile brake sheet does not have the method for manufacture of copper friction materials.
Background technology
Steel fiber and metal-powder are the important component parts of friction material formulation; In the ceramic frication material prescription; Main brass or red copper fiber and the powder thereof that uses; They not only have crucial effects to friction, the polishing machine of friction materials, but also are bearing the conduction of friction materials internal heat energy.Friction materials in use can produce great amount of heat, makes heat energy accumulate in friction material surface if can not get good conduction, and then can cause the friction materials braking function to lose efficacy, wearing and tearing increase etc. has a strong impact on the result of product performance.
Summary of the invention
The objective of the invention is to avoid the deficiency of prior art and a kind of method of manufacture of not having copper ceramic formula friction materials is provided.
The technical scheme that the present invention adopted is: the method for manufacture of no copper ceramic formula friction materials, its prescription is: (weight percent)
Sticker: 5-15%;
Strongthener: 20-30%;
Frictional property regulator: 30-50%;
Filler: 20-30%;
Wherein sticker is the silicon modified phenolic resins.
Strongthener is the mixture of alloy fiber and aramid pulp and ceramic fiber; Wherein alloy fiber is the blend fiber or the alloy fiber of aluminium, zinc, magnesium, silver, nickel, titanium, chromium, lithium or beryllium.
Frictional property regulator is made up of abrasive, lubricant, stablizer, and its ratio of component is 1:1:1---1:2:1; Abrasive can be a kind of in aluminium sesquioxide, red stone, Natural manganese dioxide or the friction powder; Lubricant can be a kind of in graphite, sulfide or the mica; Stablizer is the potassium titanate wafer.
Filler is permanent white or Natural manganese dioxide.
The technical scheme that the present invention adopted also comprises: its complete processing is put into mixing tank, stir mixing for the raw material that all prescriptions are required; Discharging is after hot-forming, and die temperature is 160 ℃, and forming pressure is 400kg/cm, and the dwell time is 10min; Abrasives after the moulding is available materials through being ground to.
Compared with prior art, advantage of the present invention is: braking ability is good, polishing machine is strong and have good heat-conductive characteristic, and noiselessness, the ash that do not have, braking are comfortable.
