Description
Technical field
The present invention relates to a kind of rubber combination that is used for automobile chassis control arm lining, be used to make automobile chassis control arm lining, belong to the rubber technology field.
Background technology
Automobile chassis is supporting, installation motor car engine and each parts thereof, assembly, forms the moulded of automobile.Accept the power of power train, the effect generation tractive force through driving wheel and road surface makes automobile normal running.Bear the gross weight of automobile and the counter-force on ground simultaneously, relax the impact that uneven road surface causes vehicle body, the vibration in the decay running car keeps the ride comfort that goes; With turning to is to cooperate, and guarantees vehicle handling stability.In the independent wheel suspension system, control arm links together car body and wheel and tire, plays the effect of control wheel.Make the wheel can be according to the wheel hop curve in movement in vertical direction, curve be important for the dynamic performance of vehicle and this beats; Control arm also will be controlled handling, maximum comfortableness and the optimized security that wheel swings simultaneously.In order to take into account these performances, the control arm bushing design is generally the Q that moves up and down to being solid construction, and the P that swings is to being hollow structure.Shown in Fig. 1-2, be the structural representation of automobile chassis control arm lining, form by metal inner pipe 1, rubber bushing 2, the metal outer pipe 3 of coaxial setting from the inside to the outside.The damping effect of this structure and handling be best, but shortcoming is can't satisfy request for utilization fatigue lifetime, through the evidence of control arm lining rack fatigue, rubber bushing 2 is prone to break in its hollow direction in actual use.And for the human consumer, rubber bushing 2 damages, and promptly the control arm lining is scrapped, and results in greater loss.
Summary of the invention
Technical problem to be solved by this invention provides a kind of rubber combination that is used for automobile chassis control arm lining, and its over-all properties is better, the longer service life of the control arm lining of processing.
In order to address the above problem, technical scheme of the present invention provides a kind of rubber combination that is used for automobile chassis control arm lining, it is characterized in that, by forming in the raw material of weight part as follows:
Preferably, described tree elastomer is that the Indonesia 1# smoke sheet rubber produced of Indonesia PTP rubber plant or Thailand are with the safe production Thailand 3# of rubber plant smoke sheet rubber.
Described p-phenylene diamine derivative is N-sec.-propyl-N '-diphenyl-para-phenylene diamine or N-(1, the 3-dimethylbutyl)-N '-diphenyl-para-phenylene diamine.
Preferably, described reaction product of acetone and amine is 2,2,4-trimethylammonium-1,2-dihyaroquinoline polymkeric substance or 6-oxyethyl group-2,2,4-trimethylammonium-1,2-dihyaroquinoline.
Preferably, described physical antioxidant is a Microcrystalline Wax.
Preferably, described promoting agent is an active oxidizer.
Preferably, the mixture of described compound silane coupling agent and carbon black is the Longsil4C that the diligent logical Industrial Co., Ltd. in Shanghai produces.
Preferably, described carbon black is the Cabot N234 that Cabot carbon black plant, Shanghai produces.
Preferably, described WHITE CARBON BLACK is produced PS-300 for Ge Lasi WHITE CARBON BLACK chemical industry ltd in raising.
Preferably, described softening agent is a Yellow Protopet 2A.
Preferably, described vulcanizing agent is a sulphur.
Preferably, described promotor is sulfenamide, thiazole accelerator or both compsns.
Further, said sulfenamide type accelerators is N-cyclohexyl-2-[4-morpholinodithio base sulphenamide or N-tertiary butyl 2-[4-morpholinodithio base sulphenamide.
Further, said thiazole accelerator is a dibenzothiazole disulfide.
The present invention is preferred a kind of with LongsilSi69 be main compound silane coupling agent and the mixture of carbon black-～Longsil4C; Its distinctive four linear sulphur are outside the vulcanization crosslinking and the anti-effect of reverting of rubber, and sulfenyl also has cooperative effect with other functional groups.4C is a carrier with the carbon black, and it is more even that silane coupling agent is disperseed in compounding rubber.Simultaneously, obtained carbon black dispersion that Si69 fully soaks in rubber structure,, made the physical and mechanical property of rubber better the combining to play and promote and enhancement of carbon black and rubber.Tensile strength, tearing toughness, wear resisting property etc. obviously improve, and tension set reduces, and can also reduce compound viscosity simultaneously, improve processing characteristics.It is the vulcanization system of usefulness also, can effectively improve the reversion resistance of tree elastomer, adds the fatigue lifetime that Longsil4C can improve automobile chassis control arm lining greatly.
The present invention finds to use separately the novel process fine intermediate super abrasion furnace black high structure can give sizing material high tear strength simultaneously, also further improves tear strength with the high structure WHITE CARBON BLACK of novel process again; And research shows and will obtain higher pivot angle fatigue lifetime that rubber just must possess high tear resistance.As everyone knows, the tear strength of WHITE CARBON BLACK is higher, but dispersed bad, and fatigue process is given birth to heat and increased, and causes range of application to receive certain limitation.And overcome this problem through the high structure WHITE CARBON BLACK of the little granulation of novel process, and having improved living heat through wet method, little granulation has solved scattering problem, and (specific surface area BET is 200m on general WHITE CARBON BLACK basis, to have improved structure level again
2/ g, the DBP oil-absorption(number) reaches 2.81cm
3/ g), further improve its dispersed and the combine brute force of raising again and with Longsil4C with rubber, significantly promoted the tear strength of rubber.Gained rubber unvulcanizate tear strength can reach more than the 140KN/m, and general natural gum tear strength (ASTM D2000 or SAE J200 standard-required >=26KN/m get final product) between 35KN/m to 60KN/m.
Rubber combination provided by the invention is used to make automobile chassis control arm lining, makes it have splendid pivot angle fatigue characteristic, has solved control arm lining rack fatigue test and multiple strengthening road and may well ask and topic satisfy domestic and international client's request for utilization fully.
