Description
Technical field:
The present invention relates to a kind of polyethersulfone ketone modified resin based friction material in the friction material field.
Background technology:
Now normally comprise several parts compositions of caking agent, strongthener, frictional property regulator (abrasive and lubricant), filler and compound with friction materials, what caking agent wherein mainly used is unmodified resol.This friction materials as matrix resin, makes the bonding friction materials product that becomes to have the required various performances of friction catch of various fortifying fibres and other components with phenolic aldehyde, and matrix resin has a very important role to whole material property.Along with transportation machinery develops to the high-speed overload direction, high-quality friction material is had higher requirement, as good fade resistance, the frictional coefficient that heat is restorative, stable, less abrasion and lower noise etc.But unmodified resol exists that fragility is big in the friction materials, poor toughness, thermotolerance be limited, can not satisfy the service requirements of modern friction materials.
Goal of the invention:
The objective of the invention is in friction material formulation, to adopt polyethersulfone ketone modified resin as main binder, change the internal structure of friction materials, improve thermotolerance, the fade resistance of friction materials, increase the service life, improve the corresponding comprehensive use properties of friction materials and a kind of polyethersulfone ketone modified resin based friction material of proposing.
Summary of the invention:
Good thermotolerance, thermostability, water-proof advantage design friction material formulation that the present invention utilizes polyethersulfone ketone modified resin to have change the material internal structure, improve its comprehensive Practical Performance.Technical scheme of the present invention is: the material by following weight percent is formed: caking agent 5～18, strongthener 20～30, abrasive 1～15, lubricant 5～15, filler 10～30, compound 20-30, caking agent wherein is a polyethersulfone ketone modified resin, strongthener is a steel fiber, aramid fiber, mineral fibre, the one or more combination of glass fibre, abrasive is an aluminium sesquioxide, ferric oxide, magnesian one or more combination, lubricant is a graphite, molybdenumdisulphide, the micaceous one or more combination, filler is a barium sulfate, potassium titanate, the one or more combination of vermiculite power, compound are lime carbonate, aramid fiber, tyre talc, the arbitrary combination of coke powder.
The invention effect:
The heat fading phenomenon does not take place in the brake facing that uses this prescription to produce during high temperature, stable friction factor, product abrasion is little, in the use braking comfortable, noiselessness produces, and reaches work-ing life more than 70,000 kilometers.
Embodiment:
Problem at prior art exists according to summary of the invention, has designed two assembly sides (A prescription and B prescription) and has tested, and experimental program and experimental result are as follows:
According to above formulating of recipe,, test: batch mixing → moulding hot pressing → thermal treatment → plain grinding → spray paint → dry → installation accessories → seal mark encapsulation according to following production technique processed sample
Test-results
From analysis of experimental data, unmodified resol (prescription A) friction materials product hardness is big, and when carrying out the decline program, fading rate is up to more than 35%, and high speed performance is relatively poor, and frictional coefficient is 0.22, has noise to produce in experimentation; And polyethersulfone ketone modified resin friction materials (prescription B) fading rate has clear improvement, and is lower than 20%, and the high-speed friction coefficient is higher than 0.28, noiselessness when experiment.
