Abstract
The invention provides a one-step sulphurating rubber-refining method comprising the following steps of: with ethylene propylene diene rubber as a raw material, slicing the rubber into needed dimensions by using a rubber cutting machine; adding sulphur and additives thereof (by mass fraction ratio): 100 parts of EPDMG-6470, 5-8 parts of zinc oxide, 1-2 parts of stearic acids, 110-120 parts of carbon black, 55-60 parts of paraffin oil, 1.5 parts of the sulphur, 1.5 parts of ZDBC, 1.2 parts of MBT and 0.8 part of TMTD (Tetramethylthiuram Disulfide); adding the materials to an internal mixer together; mixing at the temperature of 90-115 DEG C and the pressure of about 100 MPa for 350 seconds, and then sufficiently mixing the rubber and the sulphur; and after the mixing is completed, placing the mixed rubber to a rubber rack. The invention only adopts one-time sulphurating mixing under the precondition of ensuring the property of the mixed rubber and has simple process.
Description
Technical field
The present invention relates to a kind of refining gluing method, a particularly a kind of step adds the method for sulphur refining glue.
Background technology
At present, at vulcanization of rubber manufacture field, common working method is: virgin rubber and sulphur and other additive are carried out once about 150 seconds mixing, after then rubber unvulcanizate being parked 24-72 hour, add additive again, it is mixing to carry out about 70 seconds of the second time, finishes secondary and just can be used for various productions and processing after mixing.The method of this segmentation refining glue needs earlier mixingly, parks again, and last mixing process, this technological process is loaded down with trivial details, long processing time and unusual labor intensive resource.
Summary of the invention
The object of the present invention is to provide a kind ofly produce rationally, technology is simple, the process-cycle is short, the Rubber processing technology of save energy.
Technical scheme of the present invention is: a step adds the method for sulphur refining glue, it is characterized in that: the employing terpolymer EP rubber is a raw material, use bale splitter that rubber is cut into desired size, add sulphur with and additive (press massfraction compares): 100 parts of EPDM G-6470, zinc oxide 5-8 part, stearic acid 1-2 part, carbon black 110-120 part, paraffin oil 55-60 part, 1.5 parts in sulphur, ZDBC1.5 part, MBT1.2 part, TMTD0.8 part, above-mentioned materials is dropped into Banbury mixer together, under 90-115 ℃ temperature and about 100MPa pressure, carry out mixing, after mixing 350 seconds, the abundant blend of rubber and sulphur, after mixing the finishing, rubber unvulcanizate is got final product as for the glue frame.
The present invention is under the prerequisite of guaranteeing the rubber unvulcanizate performance, and it is mixing that an employing once adds sulphur, and operation is simple, saves 72 hours material setup time simultaneously and reduces by about 50% mixing time.Reduced the energy consumption in the course of processing, strengthened the protection of environment and the utilization of resource have been reduced tooling cost and process-cycle and manpower.
Embodiment
One step added the method for sulphur refining glue, the employing terpolymer EP rubber is a raw material, use bale splitter that rubber is cut into desired size, add sulphur with and additive (press massfraction compares): 100 parts of EPDM G-6470, zinc oxide 5-8 part, stearic acid 1-2 part, carbon black 110-120 part, paraffin oil 55-60 part, 1.5 parts in sulphur, ZDBC1.5 part, MBT1.2 part, TMTD0.8 part, above-mentioned materials is dropped into Banbury mixer together, under 90-115 ℃ temperature and about 100MPa pressure pressure, carry out mixing, after mixing 350 seconds, the abundant blend of rubber and sulphur, after mixing the finishing, rubber unvulcanizate is got final product as for the glue frame.
The present invention is under the prerequisite of guaranteeing the rubber unvulcanizate performance, and it is mixing that an employing once adds sulphur, and operation is simple, saves 72 hours material setup time simultaneously and reduces by about 50% mixing time.Reduced the energy consumption in the course of processing, strengthened the protection of environment and the utilization of resource have been reduced tooling cost and process-cycle and manpower.
