Specifically comprising the following steps that of described elastomeric preparation
(1) microwax, Tissuemat E, clay are carried out levigate process respectively through ball mill, standby;
(2) refining glue 2-3 minute in banbury is put into after being cut into small pieces by butadiene-styrene rubber, add aromatic naphtha, microwax, polydimethylsiloxane, Tissuemat E, accelerant CZ, antioxidant D NP, clay, triacetin, polyethylene, triethyl citrate, at 70-90 DEG C mixing 3-5 minute; Add N550 white carbon black, hydroxy silicon oil, at 90-120 DEG C mixing 6-10 minute;
(3) step 2 gained rubber is placed in vulcanizing press, adds vulcanizing agent DTDM and leftover materials, at 12-15Mpa, 80-100 DEG C vulcanizing treatment 30-60 minute;
(4) revulcanization at 12-15Mpa, 80-100 DEG C of step 3 gained synthetic rubber is processed 20-30 minute, the synthetic rubber inspection deburring that will obtain.
Beneficial effects of the present invention:
The central idea of the present invention is a kind of synthetic rubber of invention, replaces the common spring used in existing color selector vibrator, to reach better damping effect.
The synthetic rubber of the present invention can help mixing and the dispersion of filler in sizing material by the aromatic naphtha added, and significantly improves the processing characteristics of rubber, it is possible to strengthens the weathering resistance of rubber product, oxidation, friction, aging degree.
The interpolation of modification infusorial earth can improve elastomeric performance, 10 added in modification infusorial earth, the double; two phenoxazine arsenic of 10 '-oxo can suppress mycete, prevent rubber from going mouldy, 2,2 '-thiobis (4-t-octyl phenol oxygen base) nickel can reduce light-emitting phosphor intensity, it is prevented that rubber generation light degradation.
Specific embodiments
Below in conjunction with detailed description below, the present invention is described in further detail:
The raw material weighing following weight portion (kg) is made: butadiene-styrene rubber 75, aromatic naphtha 3, vulcanizing agent DTDM2, microwax 2, hydroxy silicon oil 2, polydimethylsiloxane 1, Tissuemat E 2, triacetin 2, accelerant CZ 1, N550 white carbon black 35, antioxidant D NP2, clay 4, polyethylene 3, triethyl citrate 4, modification infusorial earth 11;
