Described modification infusorial earth is made up of the raw material of following weight part: diatomite 40-50, titanium dioxide 6-8, lithopone 3-4, xylogen 2-4, pearlstone 5-8, iron trichloride 3-5, butyraldehyde-n-aniline condensation thing 2-4, Praseodymium trioxide 1-2, beeswax 6-8,10,10 '-oxo two phenoxazine arsenic 2-3,2,2 '-thiobis (4-tertiary octyl phenol oxygen base) nickel 1-3; Its preparation method is that hydrochloric acid soln diatomite being placed in 5%-10% soaks 40-60 minute, by gained drying materials after suction filtration, mix with pearlstone again, high-temperature calcination 1-2 hour is carried out at 750-800 DEG C, mix with beeswax again after taking out cool to room temperature, grind to form 120-160 object fine powder by shredder, finally mix with surplus material, make the abundant dispersing and mixing of all raw material powders evenly by ball milling.
The concrete steps of described elastomeric preparation are as follows:
(1) vermiculite is carried out levigate process by ball mill, for subsequent use;
(2) drop in Banbury mixer after diolefine synthetic rubber, terpolymer EP rubber being cut into small pieces and refine glue 2-3 minute, add tetrafluoroethylene, dioctyl phthalate (DOP), Vaseline, Imarcaptoacetate dioctyltin, altax, antioxidant D, dibutyl phthalate again, mixing 3-5 minute at 70-90 DEG C; Add N330 carbon black again, mixing 6-10 minute at 90-120 DEG C;
(3) step 2 gained rubber is placed in vulcanizing press, then adds zinc oxide, oligomer ester, high density polyethylene(HDPE) and leftover materials, sulfidizing 30-60 minute at 12-15Mpa, 80-100 DEG C;
(4) by step 3 gained synthetic rubber revulcanization process 20-30 minute at 12-15Mpa, 80-100 DEG C, by the synthetic rubber inspection deburring obtained.
Beneficial effect of the present invention:
Clou 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.
Synthetic rubber of the present invention, by adding dibutyl phthalate, makes product have good flexibility, is convenient to further utilization, and the interpolation of Imarcaptoacetate dioctyltin can prevent rubber from decomposing, aging.
The interpolation of modification infusorial earth can improve elastomeric performance, 10 of interpolation, and the two phenoxazine arsenic of 10 '-oxo can mould fungus inhibition, prevent rubber from going mouldy, 2,2 '-thiobis (4-tertiary octyl phenol oxygen base) nickel can reduce light-emitting phosphor intensity, prevents rubber generation photodegradation.
