Description
Technical field
The present invention relates to automobile chassis suspension systems technology field, particularly relate to a kind of rack buffer dw and preparation method thereof.
Background technology
Automobile chassis suspension system is one of key components and parts affecting car comfort, and its effect is the force and moment transmitting vehicle frame and axletree; Relax the shock load that vehicle frame is passed on road surface, the vibration of the load system caused thus of decaying, ensures ride of vehicle; Ensure that wheel has desirable motion characteristics when Uneven road and load change, ensure the control stability of automobile; Rack buffer dw is for chassis suspension system, and when automobile turning, travel and jolt in the moving processes such as road conditions, mainly play the effects such as supports, location, buffering, absorbing and noise reduction, improvement is handling, comfortableness and stability by bus.
Existing factory is saving material cost and assembly cost, by spring pad and dust boot design integralization structure.Spring pad position requires that product has good elasticity and damping performance, and dw position needs good aging resistance and ozone resistance.When this series products adopted natural rubber to make in the past, there is dw position and easily lost efficacy because thermotolerance is not high and ozone resistance is poor; When adopting terpolymer EP rubber to make, damping performance and the fatigue endurance performance at its spring pad position can not meet the demands and lose efficacy again.
Summary of the invention
In view of this, one aspect of the present invention provides a kind of rack buffer dw, while the dw position of this suspension dw has good thermotolerance and ozone resistants, the spring pad position of rack buffer dw also has good damping performance and fatigue performance, the invention solves the defect problem by spring pad and dust boot design integralization structure.
For reaching this object, the present invention by the following technical solutions:
A kind of rack buffer dw, by weight, comprises following component:
Preferably, this rack buffer dw also comprises dispersion agent 2 ~ 6 parts, scorch retarder 0.2 ~ 0.6 part, sulfuration resistant reductive agent 0.5 ~ 0.8 part.
Preferably, promotor is made up of vulkacit D TDM1 ~ 2 part, accelerant CZ 1 ~ 2 part, and anti-aging agent is made up of antioxidant 4020 1 ~ 3 part, anti-aging agent RD 2 ~ 4 parts, and promoting agent is made up of indirect process zinc oxide 4 ~ 6 parts, stearic acid 0.5 ~ 2.5 part.
Stearic acid plays an important role in the synthesis and the course of processing of rubber.Stearic acid is the vulcanization leveller of widespread use in natural rubber, synthetic rubber and latex.
Indirect process zinc oxide, take zinc ingot metal as raw material, zinc ingot metal is converted to zinc fume in plumbago crucible under the high temperature of 1000 DEG C, is generated zinc oxide subsequently, and after cooling tube, collect to obtain Zinc oxide particles by the atmospheric oxidation blasted.Can be used as vulcanization of rubber promoting agent, strengthening agent.
DTDM name is called 4,4`-dimorpholinyl disulfide, it can be used as the effective promotor of sulfur cross-linking of natural gum and synthetical glue, and it is high that its cross-linked rubber has mechanical property, and ozone resistance is high, the advantage of the good and rubber unvulcanizate of ozone resistance not incipient scorch, especially good with sulfenamide type accelerators combined effect, there is outstanding heat-resistant aging, no blooming, and compression set is little, can be used in tire and technical rubber goods.
Accelerant CZ name is called N-cyclohexyl-2-benzothiazole sulfonamide, and CZ is the aftereffect promotor that a kind of height is active, and scorching quality is excellent, process safety, curing time is short, and when curing temperature more than 138 DEG C, promoter action is very strong, often coordinates work second promotor with DTDM promotor.
Anti-aging agent refers to prevent or suppress the factors disrupt product propertiess such as such as oxygen, heat, light, ozone, mechanical stress, heavy metal ion, extend goods storage and the Synergist S-421 95 in work-ing life, and the aging protection effect caused heat and oxygen is splendid.Anti-aging agent RD is 2,2,4-trimethylammonium-1,2-dihyaroquinoline polymer; 2,2,4 trimethyl 1,2 dihydroquinoline polymer; The homopolymer of 1,2-dihydro-2,2,4-trimethylquinoline; 2,2,4-trimethylammonium-1,2-dihyaroquinoline.RD and 4020 with making goods have ozone-resistant and anti-flexing fatigue performance.Antioxidant 4020 name is called N-(1,3-dimethyl) butyl-N'-diphenyl-para-phenylene diamine, natural rubber and use for synthetic rubber antiozonidate and oxidation inhibitor, to ozone-induced cracking and the aging protective benefits of flexing fatigue excellent, also have good protective effect to heat, oxygen and the poisonous metal such as copper, manganese.
Preferably, carbon black is carbon black N-330, and dispersion agent is that a part T moulded by Lay mattress, and lubricant is paraffin B-10, and scorch retarder is anti-scorching agent CTP, and superoxide is DCP, and sulphur is insoluble sulfur IS-60, and sulfuration resistant reductive agent is SR534D.
