Description
Technical field
The present invention relates to a kind of automobile chassis suspension high temperature resistant fatigue rubber composition, for making automobile chassis
Arm bush is controlled, belongs to field of rubber technology.
Background technology
Chassis suspension is that isolation road vibration transmits to in-car, is to influence vehicle to drive impression and riding comfort
Key components and parts, in the process of moving, the size of in-car vibration and noise, chassis suspension serves very important vehicle
Effect.Suspension can be housed between body of a motor car and chassis, primarily serve isolation road vibration, decay road excitation and right
Circumferential component carries out the effect of confining guard；Its critical piece is made up of control arm assembly and elastomeric bushing；Primarily serve fast
The vibration that speed decay road surface is transmitted to in-car, improve ride comfort, comfortableness and the security of running car.
For offroad vehicle because of its special traveling road conditions, the load that shock absorbing bushing is subject in use is bigger, and heat is also more
Greatly, if the high temperature resistant fatigue behaviour of rubber shock-absorbing bushing is bad, if being broken during use, potential safety hazard can be caused, and need
Whole suspension assembly is changed, adds maintenance cost；So to determine that elastomeric material will meet good resistance to for its use condition
Dynamic high temperature fatigue behaviour requirement, to meet the comfortableness and security in vehicle travel process, it is therefore desirable to ensureing to take
On the premise of comfortableness, the high temperature resistant dynamic fatigue property ever more important of existing rubber composition is improved.
The content of the invention
Problem to be solved by this invention is to provide a kind of automobile chassis suspension high temperature resistant fatigue rubber composition.
In order to solve the above problems, the technical scheme is that it is tired to provide a kind of automobile chassis suspension high temperature resistant
Labor rubber composition, it is characterised in that include component as follows in parts by weight：
Preferably, the natural rubber uses SVR3L and ENR by weight 65: 35 Blend rubber.
Preferably, the physical antioxidant uses ANTIWAX 6268.
Preferably, the reinforcing agent is using Cabot N-234 carbon blacks and nano modification kaolin NCL-302 mixture.
Preferably, the plasticizer uses environment-friendly aromatic oil VIVATEC500.
Preferably, the assistant crosslinking agent uses SV207.
The present invention has selected Vietnam's SVR3L natural rubbers and epoxidation natural gum blend, and (SVR3L and ENR are common by 65: 35
It is mixed), wherein ENR is and preparation, ring after being oxidized by the partial double bond on epoxidation modification natural rubber rubber molecular chain
Oxidation after rubber macromolecule polarity increase, intermolecular force enhancing, therefore make ENR both remained with NR basic structure and
Performance characteristics, many unique performances are generated again, are mainly had：Excellent air-tightness, excellent oil resistivity, compatibility, moisture-resistant
Good adhesive property between slip, low rolling resistance and other materials etc.；It is original excellent in NR by being blended to use with NR
On the basis of performance, the combination property of vulcanizate is improved.Heat-resisting, anti-aging property to ensure excellent have selected stability
German Chinese sage environment-friendly aromatic oil VIVATEC500 good, flash-point is high.It is to ensure sulphur from Cabot super abrasive carbon black N-234
Change the combination properties such as the excellent tensile strength of glue, tearing strength, and be to reduce life with nano modification kaolin NCL-302
Heat, so that rubber reaches balance in each side such as tensile strength, tearing strength, heat build-ups.It is anti-old from new physics
Agent ANTIWAX 6268 is used in combination with p phenylenediamine type antioxidant, plays synergy, is to ensure more excellent ozone and heat
Oxygen barrier propterty.What assistant crosslinking agent was selected is that novel and multifunctional crosslinking aid S V207 is to ensure good dynamic static modulus, drawing
Stretch intensity, tearing strength, hardness, resilience, compression, heat etc., in the sulfur cross-linking that SV207 is participated in, thermodynamics will be formed
Mixing cross-bond stable and that tool is flexible, structure is " rubber-Sx-(CH2)6-Sx- rubber " (X≤3).
Production process of the present invention is easy to operate, it is not necessary to which special processing technology, gained rubber have splendid high temperature resistant
Dynamic fatigue property.
