Description
Technical field
The present invention relates to field of rubber technology, is a kind of for injection process soft EPT rubber composition specifically.
Background technology
Along with the requirement of automobile high performance, lightweight and comfortableization is more and more higher, require more and more wider to rubber part on automobile, such as, orthodox car is that the requirement durometer level of terpolymer EP rubber material is generally at 50 ~ 70 degree to material, but, in order to make a certain rubber part on automobile reach more comfortableization, the rubber hardness that obtain is 30 degree.
As everyone knows, for terpolymer EP rubber basic components durometer level at 55 ~ 60 degree, so, want to obtain more low-hardness rubber goods, just must add a large amount of tenderizers in rubber, simultaneously, terpolymer EP rubber is non-self reinforced rubber, also the tensile strength that strengthening agent increases rubber must be added while adding tenderizer, strengthening agent only has and is dispersed in very well in rubber and can plays strengthening action, strengthening agent is dispersed in the main shearing action relying on Banbury mixer two rotors in rubber, what only reach that certain shearing force strengthening agent just may disperse is even, be 30 degree of common formula of ethylene propylene terpolymer with for hardness, because rubber hardness is lower, time mixing, Banbury mixer two rotor shearing forces are less, strengthening agent is difficult to the even of dispersion, show the dispersion of vulcanising rubber surface strengthening agent uneven, tensile strength is relatively low, can not meet demand, simultaneously, because rubber hardness is lower, glue stuff compounding is difficult to shaping, moreover shaping rear adhesive tape is easy to stick together, the requirement of injecting glue sulfuration process can not be met.
