Abstract

The invention relates to a novel ceramic brake pad which has high toughness and abrasive resistance. After being added with cellulosic fibers, the novel ceramic brake pad can insulate noise, while heat stability can be guaranteed to be high. Besides, friction performance can be adjusted by means of adopting friction material with different granularities, and meanwhile noise and vibration of brakes can be reduced. Artificial graphite has excellent performances such as conductivity, thermal shock resistance and corrosion resistance, can play a role of friction reducing with added nitrile rubber, and can effectively protect the brake pad. The invention further provides a method for producing the ceramic brake pad.

Description

A kind of Novel ceramic brake pad

Technical field

The present invention relates to Motor Vehicle Component field, specifically a kind of Novel ceramic brake pad.

Background technique

Brake block is also brake rubber block.In the brake system of automobile, brake block is the breaking piece of most critical, and the quality of all braking effects is all that brake block plays a decisive role, so the brake block of agreeing is the patron saint of people and automobile.Brake block is generally made up of steel plate, bonding thermal-protective coating and brake pad, and steel plate will come antirust through gluing, and wherein thermal-protective coating is made up of adiabatic material, and object is heat insulation.Brake pad is made up of friction material, tackiness agent, is compressed on brake disc or brake drum and produces friction, thus reach the object of vehicle deceleration brake during brake.Due to rubbing action, brake pad can be worn gradually, and the brake block that cost is lower in general weares and teares faster.

Brake block roughly can be divided into semimetal by constituent, few metal, asbestos, pottery.Due to the difference of the braking effect of various brake block, temperature conductivity, manufacture cost, also do not have now a kind of can good braking effect, the ceramic brake that heat-conducting property cost performance that is good, low cost of manufacture is higher of the various brake block advantage of set.

Summary of the invention

The present invention is above technical problem just, provide a kind of can good braking effect, the ceramic brake that heat-conducting property cost performance that is good, low cost of manufacture is higher of the various brake block advantage of set.

The present invention is achieved through the following technical solutions:

A kind of Novel ceramic brake pad, it is characterized in that this Novel ceramic brake pad forms: Fen Chuo resin 5% ~ 8% by weight percentage primarily of following component, red copper fiber 8% ~ 12%, cellulose fiber 1% ~ 4%, potassium hexatitanate 8% ~ 13%, aramid fibre 1% ~ 4%, mineral fibre 8% ~ 12%, oil coke 6% ~ 10%, barium sulphate 8% ~ 12%, aluminium oxide 0.5% ~ 2%, Cosan 0.5% ~ 2%, lithopone 6% ~ 12%, artificial graphite 4% ~ 8%, white vermiculite power 4% ~ 8%, iron oxide yellow 1% ~ 4%, friction particles 4% ~ 8%, zinc powder 1% ~ 4%, Frication powder 2% ~ 4%, nitrile butadiene rubber 2% ~ 4%.

In the present invention, mineral fibre has higher toughness and wear resistance, main rising is reinforced, shock resistance, prevent the effects such as crackle, white vermiculite power has lightweight, good thermal stability, the features such as heat conductivity is low, after adding cellulose fiber, while guarantee high thermal stability, the effect of isolated noise can be played, in addition, adopt varigrained friction material, frictional behaviour can be adjusted, brake noise and vibrations can be alleviated simultaneously, artificial graphite conductivity, thermal shock resistance, play the excellent performances such as corrosivity, add nitrile butadiene rubber and can play anti-attrition effect, again can available protecting brake block.

In order to effectively realize the present invention, the present invention also works out the brake block production and processing method that a kind of technological process is simple, manufacturing efficiency is high, and its concrete steps are as follows:

A production method for Novel ceramic brake pad, comprises the following steps:

Step one: steel backing pretreatment

It is for subsequent use after ball blast, gluing are carried out to steel backing;

Step 2: batching

Take each component materials by the component proportion of design, be placed in batch mixer, be mixed into uniform mixture for subsequent use;

Step 3: machining

The brake block specification of being produced on demand by the mixture of step 2 takes predetermined weight, is pressed on steel backing, then heat-treats, grinding, the process such as sandblasting make semi-finished product;

Step 4: finished product is processed

The semi-finished product of step 3 gained are sprayed, and loads onto bloop, after then carrying out coding, riveted joint, can warehouse-in be packed.

Embodiment

The present invention will be further described to lift specific embodiment below.

Embodiment 1

Take following component: Fen Chuo resin 6% by weight percentage, red copper fiber 10%, cellulose fiber 3%, potassium hexatitanate 11%, aramid fibre 3%, mineral fibre 10%, oil coke 8%, barium sulphate 11%, aluminium oxide 1%, Cosan 1%, lithopone 8%, artificial graphite 6%, white vermiculite power 6%, iron oxide yellow 2%, friction particles 6%, zinc powder 2%, Frication powder 3%, nitrile butadiene rubber 3%, be placed in batch mixer, be mixed into uniform mixture, then mixture is taken by the brake block specification of producing, mixture is compressed on through ball blast, on the steel backing of gluing, after Overheating Treatment, by grinding, unnecessary mixture is ground off, then carry out sandblasting and make semi-finished product, finally semi-finished product are sprayed, and load onto bloop, then coding is carried out, after riveted joint, be packaged into stock.
