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.
