Description
Technical field
The present invention relates to a kind of nano copper resin base friction material in the friction material field.
Background technology
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.Matrix resin has a very important role to whole material property.Along with transportation machinery develops to the high-speed overload direction, friction materials is had higher requirement, as good fade resistance, stable frictional coefficient, less abrasion and lower noise, little etc. to the mating plate wearing and tearing.Existing friction materials comprises that mainly employing resol as caking agent, cooperates strongthener, abrasive, lubricant, filler, other compound; Its technical process is: batch mixing → moulding hot pressing → thermal treatment → plain grinding → spray paint → dry → installation accessories → seal mark encapsulation.But now with unmodified resol in the friction materials have that fragility is big, poor toughness, poor thermal conductivity, thermotolerance are limited etc., can not satisfy the service requirements of modern friction materials.
Summary of the invention
Nano copper resin base friction material purpose of the present invention is to adopt nanometer copper modified phenolic resins as main binder in friction material formulation, change the internal structure of friction materials, the thermotolerance, the fade resistance that improve friction materials increase the service life, and improve the corresponding comprehensive use properties of friction materials.
The advantages such as good thermotolerance, thermal conductivity, thermostability and high impulse strength that the present invention utilizes nanometer copper modified phenolic resins to be had are sent out the meter friction material formulation, change the material internal structure, improve its comprehensive use properties.It is as follows to constitute raw material of the present invention and weight part: adopt nanometer copper modified phenolic resins as caking agent, its umber 5～12; Strongthener is selected the one or more combination in steel wool fiber, aramid fiber, mineral fibre, the glass fibre for use, its umber 20～30; Abrasive comprises the one or more combination in aluminium sesquioxide, ferric oxide, the magnesium oxide, its umber 1～15; Lubricant comprises the one or more combination in graphite, molybdenumdisulphide, the mica, and its umber is 5-15; Filler comprises one or more of barium sulfate, potassium titanate, vermiculite power, and its umber is 10～30; Other compound comprises the arbitrary combination of lime carbonate, aramid fiber, tyre talc, coke powder, its umber 20～35.
The invention effect: the brake facing that uses the present invention to produce, the heat fading phenomenon does not take place during high temperature, stable friction factor, product abrasion is little, shock strength improves about 40%, in the use braking comfortable, noiselessness produces, and reaches work-ing life more than 70,000 kilometers.
