Abstract
The invention relates to a friction material of rubber modified resin groups belonging to the field of the friction material. The invention comprises following raw materials and parts by weight: adopting rubber modified resin as binder, reinforced materials comprises one or multiple combination of steel wool fiber, aramid fiber, mineral fiber and glass fiber, abrasive comprises one or multiple combination of aluminum oxide, ferric oxide and magnesium oxide, lubricant comprises one or multiple combination of graphite, molybdenum disulfide and mica, extender comprises one or multiple combination barium sulfate, potassium titanate and vermiculite powder, and the other mixture comprises any combination of calcium carbonate, aramid fiber, tyre powder and coke powder. Using the brake block prepared by the invention, the phenomenon of heat fading can not to appear, friction coefficient is steady, abrasion wear of product is little, impulse strength improves about 40%, braking is comfortable without noise and the service time is more than 70 thousand kilometers.
Description
Technical field
The present invention relates to a kind of rubber modified resin base frication 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 resol.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 resin 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
Rubber modified resin base frication material purpose of the present invention is to adopt rubber modified resin 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.
Advantages such as good thermotolerance, thermal conductivity, thermostability and the high impulse strength design friction material formulation that the present invention utilizes rubber modified resin to have changes the material internal structure, improves its comprehensive use properties.It is as follows to constitute raw material of the present invention and weight part: adopt rubber modified resin 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.
Embodiment
The comparative example: the problem at prior art exists, according to summary of the invention, designed two assembly sides (A prescription and B prescription) and compared test, experimental program and experimental result are as follows:
| Prescription A | Prescription B | ||
| Title material | Weight part | Title material | Weight part |
| Resol | 8 | Rubber modified resin | 8 |
| Steel fiber | 25 | Steel fiber | 25 |
| Ferric oxide | 8 | Ferric oxide | 8 |
| Graphite | 6 | Graphite | 6 |
| Potassium titanate lamella crystal | 20 | Potassium titanate lamella crystal | 20 |

| Water-ground limestone | 10 | Water-ground limestone | 10 |
| Aramid fiber and tyre talc | 20 | Aramid fiber and tyre talc | 20 |
| Testing program | Processing red flag vehicle anter uses the KRAUSS trier to carry out engine bench test according to foundation AK-Master standard | ||
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
(2) test-results
From analysis of experimental data, unmodified resin (prescription A) friction materials product hardness is big, poor toughness, 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 rubber 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.
On the basis of the foregoing description, can also adjust the increase coke powder in the raw material, have same performance.
Claims (1)
1. rubber modified resin base frication material, it is as follows to it is characterized in that constituting raw material of the present invention and weight part: adopt rubber modified resin as caking agent, its umber 5～12; Strongthener comprises the one or more combination in steel wool fiber, aramid fiber, mineral fibre, the glass fibre, 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.
