After lose small, heat is low, and elasticity is good, is well suited for doing vibration-damping rubber material.
The peptizer is the peptizer of thiophenols, such as pentachlorothiophenol.Their effect is enhanced by chemical action
Effect is practiced in the modeling of raw rubber, shortens to mould and practices the time, achievees the purpose that reduce the energy.
The reinforcing filler is one of N200-N900 series carbon black, spray carbon black, semi-reinforcing hydrocarbon black or a variety of
And with (press 3778 rubber grade carbon black standard of GB/T), dosage is in defined parts by weight.These carbon blacks are easy in processing
It is kneaded, elasticity is good for vulcanizate, and heat is low, and dynamic property is good.
The activating agent is made of zinc oxide and stearic acid, can activate entire vulcanizing system, improves the crosslinking of vulcanizate
Density, wherein 2~5 parts of zinc oxide, 2~3 parts of stearic acid.
The protection wax is paraffin and microcrystalline wax, can be applied alone or be used in combination.
The anti-aging agent is N- (1,3- dimethylbutyl) N/- diphenyl-para-phenylene diamine (6PPD) and trimethyl -1 2,2,4-,
2- dihyaroquinoline condensate (TMQ), dosage is in defined parts by weight.
Protection system uses anti-aging agent TMQ+ protection wax+anti-aging agent 6PPD, has excellent antioxygen, ozone-resistant, anti-deflects
Effect, also has preferable protective action to Weather, and have passivation to variable valency metal, for the rubber that must be used for a long time
Glue resilient cushion can be protected for a long time.
The softening agent be pitch, coumarone indene resin, aromatic naphtha, pine tar and naphthenic oil etc. it is one of or two kinds simultaneously
With dosage is in defined parts by weight.
The vulcanizing agent is that one of sulphur and insoluble sulfur or two kinds are used in combination.
The vulcanization accelerator is N cyclohexyl 2 benzothiazole sulfenamide (CZ), dibenzothiazyl disulfide (DM),
One of 2-mercaptobenzothiazole (M) and diphenylguanidine (DPG) or it is a variety of be used in combination, dosage is in defined parts by weight.
The antiscorching agent is N- cyclohexyl thio phthalimide (CTP), and CTP is generally acknowledged fitst water antiscorching agent, be can be improved
The process safety of sizing material.
Zinc oxide and stearic acid constitute activation system in sulfur cross-linking system in vulcanizing system of the present invention, activation
Entire vulcanizing system, improves the crosslink density of vulcanizate, sulphur-accelerator dosage of high mixture ratio improves the heat-resisting of vulcanizate
Ageing properties are used in combination using thiazole accelerator DM and guanidines DPG, can make sizing material that there is longer glue to burn the time, compared with
The ageing-resistant performance of vulcanizate can be improved in fast curingprocess rate.
Resilient cushion rubber material ingredient of the present invention is simple, convenient for rubber mixing technique operation and raw materials inventory management.
Resilient cushion rubber of the present invention is placed on rail in the following, not having to generally further take out to come, and it requires and the rail same service life.Together
The load of its receiving of Shi Yaoqiu is especially big, and the time is again long, and the requirement to its performance is just very high.
Resilient cushion rubber material of the present invention is using conventional refining gluing method preparation, and the performance of resilient cushion rubber obtained is after tested
Performance is as shown in table 1:
Table 1: properties of rubber
