Abstract
The invention relates to a compound modified phenolic resin-based friction material, belonging to the new material field. The invention adopts the technical proposal that the friction material comprises materials with the following weight percentage: adhesives 5 to 18, reinforcing material 20 to 30, abrasive material 1 to 15, lubricant 5 to 15, filling material 10 to 30, and mixture 20 to 30; wherein the adhesives is compound modified phenolic resin, the reinforcing material is one or a plurality of combinations of steel fiber, aramid fiber, mimeral fiber, and glass fiber, the abrasive material is one or a plurality of combinations of alumina, ferric oxide, and magnesia, frictional property conditioning agent is one or a plurality of combinations of graphite, supramoly, and mica, and the filling material is one or a plurality of combinations of barium sulphate, potassium titanate and vermiculite powder. By using a brake lining produced with the material, the invention has the advantages that no heat fading phenomenon happens at high temperature, the friction coefficient is stable, the wear abrasion of the product is small, the brake is comfortable when in the use, no noise is generated, and the service life is more than 70,000 kilometers.
Description
Technical field:
The present invention relates to a kind of composite modified alkyd resin based friction material in the field of new.
Prior art:
Now normally comprise several parts compositions of caking agent, strongthener, frictional property regulator, 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 composite modified alkyd resin as main binder, change the internal structure of friction materials, improve the corresponding comprehensive use properties of thermotolerance, fade resistance and friction materials of friction materials, and a kind of composite modified alkyd resin based friction material that proposes.
Summary of the invention:
The present invention utilizes advantage design friction material formulations such as good thermotolerance that composite modified alkyd resin has, thermostability, water tolerance, changes the material internal structure, improves its comprehensive Practical Performance.Technical scheme of the present invention is:
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 composite modified alkyd 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, micaceous one or more combination, filler are barium sulfate, potassium titanate, the one or more combination of vermiculite power, compound comprises 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 compared test, and experimental program and experimental result are as follows:
| Prescription A | Prescription B | ||
| Title material | Weight percent (%) | Title material | Weight percent (%) |
| Resol | 8 | Composite modified resin | 8 |
| Steel fiber | 22 | Steel fiber | 22 |
| Ferric oxide | 8 | Ferric oxide | 8 |
| Graphite | 6 | Graphite | 6 |
| Potassium titanate lamella crystal | 20 | Potassium titanate lamella crystal | 20 |
| Barium sulfate | 10 | Barium sulfate | 10 |
| Compound | 26 | Compound | 26 |
| Testing program | Processing Santana 2000 vehicle anters use the KRAUSS trier to carry out engine bench test according to the 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.
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 composite modified alkyd 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.
