Preferably, described natural rubber is the western SMR CV60 in Malaysia.
Preferably, described cis-1,4-polybutadiene rubber is BR9000.
Preferably, described p phenylenediamine type antioxidant is N-sec.-propyl-N '-diphenyl-para-phenylene diamine and N, and N '-di tolyl p phenylenediamine be take the mixture that ratio that mass ratio is 1:1 is mixed.
Preferably, described dihyaroquinoline class anti-aging agent is 2,2,4-trimethylammonium-1,2-dihyaroquinoline polymkeric substance.
Preferably, described physical antioxidant is Microcrystalline Wax 1900.
Preferably, described softening agent is the holy paraffin oil TUDALEN16 of the German Chinese.
Preferably, the fast extrusion carbon black N-550 that described strengthening agent provides for Cabot Co.,Ltd.
Preferably, described promoting agent is STRUKTOL WB700 (zinc oxide that contains 91wt% and the dispersion agent of 9wt%).
Preferably, described vulcanizing agent is soluble sulfur SU120.
Preferably, the composition that described promotor is thiazoles and sulfenamide type accelerators arbitrary proportion.
Further, described thiazole accelerator is dibenzothiazyl disulfide.
Further, described sulfenamide type accelerators is N-cyclohexyl-2-[4-morpholinodithio sulphenamide.
The present invention has selected more general natural rubber that the permanent viscose of the western SMR CV60 in Malaysia of the characteristics such as better tensile strength, wear resistance and processing stability is arranged.For guaranteeing excellent heat-resisting, the holy paraffin oil TUDALEN16 of the elite German Chinese with good stability flash-point high (40 degrees centigrade of kinematic viscosity 488, flash-point 304) of ageing resistance.P phenylenediamine type antioxidant has been selected N-sec.-propyl-N '-diphenyl-para-phenylene diamine and N, in the 1:1 ratio and with playing synergy, (anti-aging agent N-sec.-propyl-N '-diphenyl-para-phenylene diamine provides the protective effect of short-term to N '-di tolyl p phenylenediamine (mixture), anti-aging agent N, N '-di tolyl p phenylenediamine plays long-term protective effect) made up that anti-aging agent initial stage protection effect is good and the later stage is protected not enough phenomenon.It is in order to guarantee that sulphur can be dispersed in sizing material fast and effectively that vulcanizing agent is selected the STRUKTOL soluble sulfur SU120 processed through dispersion agent.Selecting Cabot to extrude soon carbon black N-550 is in order to guarantee that (N-550 is the soft carbon of high structure for tensile strength that cross-linked rubber is good, rebound resilience, low dynamic heat build up and lower dynamic property, can give the cross-linked rubber good elasticity and restore row, therefore can make cross-linked rubber obtain lower dynamic property, guarantee the lower output ratio of Q-switching to free running) etc. over-all properties.It is in order to guarantee that Synergist S-421 95 more is evenly dispersed in rubber that promoting agent selects STRUKTOL WB700 (containing 91% zinc oxide and 9% dispersion agent) to replace conventional active zinc flower, improves the quality of rubber unvulcanizate.
Advantage of the present invention has been to provide the various new auxiliary agent and has replaced conventional auxiliary agent, and production process is easy to operate, does not need special complete processing, gained rubber combination stable physical property, and after sulfuration, resulting product has splendid dynamic fatigue resistance energy.
