Abstract
The invention discloses the preparation method of automobile-used resin based powder metallurgy potassium titanate composite friction material.This preparation method, first by matrix powder material and forming agent mix homogeneously, is poured mould into and is pressed into many elongated rod-shaped, by each elongated rod-shaped pressed compact, separate, load in sintering furnace, temperature rise under conditions of being passed through nitrogen or hydrogen, obtain iron-based powder metallurgy friction material;Shear, pulverize, sieve;By percentage to the quality, cashew nut oil modified alkyd resin 10 20%, iron-based powder metallurgy friction material 30 50%, potassium titanate fibre 10 30%, abrasive material 5 15%, lubriation material 10 20% and filler 5 20% are blended uniformly;Hot-forming, cooling, come out of the stove.The feature that the present invention combines iron-based powder metallurgy friction material abrasion high temperature resistant, low and potassium titanate resin-base composite friction material good toughness, hardness is low, resulting materials has abrasion high temperature resistant, low, good toughness, characteristic that hardness is low simultaneously.
Description
Technical field
The present invention relates to a kind of resin-base composite friction material, particularly relate to potassium titanate fibre and ferrous based powder metallurgical
Material is main composite friction material and preparation method thereof.
Background technology
Composite friction material is by low with intensity for the material of different physicochemical characteristics, the high molecular polymer matrix group of good toughness
Become.Owing to macromolecular material is generally not capable of bearing high stress and high temperature, strong in order to improve the surrender of macromolecular material
Degree, improves its high-temperature stability, all uses cancellated thermosetting resin, the most various modified high temperature phenolic resin.With
Time, in order to reach preferable braking effect and comprehensive mechanical performance, also need to add various fiber, lubriation material, abrasive material and filling out
Material, and polymer matrix material therein is almost intended only as transmission or the medium of distractive load.Therefore, composite friction material
Intensity depends primarily on the adhesion strength of other component including reinforcing fiber and basal body interface.Potassium titanate crystal whisker, outward appearance
Pattern white, needle-shaped crystals;Whisker size: diameter 0.5~1.0 μm, length 10~40 μm is the thinnest monocrystal, and diameter is usual
The most several microns.Whisker can be used as the reinforcement of parent phase material, it is possible to as the enhancing of other materials, be widely used in plastics,
The enhancing of rubber, metal alloy, glass, pottery, composite etc..Resin base potassium titanate fibre composite friction material is at common in-vehicle
With having preferable friction and wear characteristic in brake, but under the braking condition of high-speed overload, friction high temperature can cause it
More serious heat fading phenomenon, and with the increase of abrasion.At present at the braking condition of the high-speed overload such as aircraft and high-speed railway
Under, owing to friction high temperature causes the high molecular polymer in composite friction material to decompose oxidation, lose stable frictional damping
Energy.Therefore frequently with powder metallurgy friction material.
Iron-based powder metallurgy friction material is with Fe powder as matrix, adds suitable anti-friction composition and increases grinding agent, uniformly mixing
The most compressing or pressure sintering.It is a kind of excellent brake friction material, especially for heavy duty braking at a high speed
Occasion, its excellent thermal diffusivity and thermostability, it is ensured that it completes more harsh braking function.Most military aircrafts
Powder metallurgy brake flat is all used with civil aircraft.But the rigidity stronger due to iron-based powder metallurgy friction material and hardness,
Easily cause automobile brake disc or the scuffing of drum and frictional noise.Therefore iron-based powder metallurgy friction material is also seldom in automobile system
Use on dynamic device.
Summary of the invention
Present invention aim to overcome that the problem that prior art exists, high temperature resistant in conjunction with iron-based powder metallurgy friction material,
The feature of low abrasion and potassium titanate resin-base composite friction material good toughness, the feature that hardness is low, it is provided that one has resistance to simultaneously
High temperature, low abrasion, good toughness, the automobile-used resin based powder metallurgy potassium titanate fibre friction material of the low feature of hardness and preparation side thereof
Method.This material is used for preparing braking automobile accessory, on the basis of there is good braking quality, be prevented effectively from automobile brake disc or drum
Scratch, and frictional noise is little.
The object of the invention is achieved through the following technical solutions:
The preparation method of automobile-used resin based powder metallurgy potassium titanate composite friction material, comprises the steps:
