Complete processing of the present invention is:
1, batching first: by prescription first get cis-butadiene cement, butylbenzene micelle, solution polymerized butadiene styrene rubber, nitrile rubber, silicon-dioxide, coupling agent, zinc oxide, rosin, promoting agent, stearic acid, protective agent, Microcrystalline Wax, anti-acid regurgitation agent prepare burden first, mixing evenly, make formulated rubber material first.
2, feed intake, banburying: the formulated rubber material first for preparing is thrown in the Banbury mixer, with the mixing 6-10 of the pressure of weight 1 ± 0.2Mpa minute, rise the ventilative 20-40 of weight stirring second then, behind the powder on the cleaning weight, depress the weight banburying again 4-6 minute, open dustproof door cleaning powder, rising weight all mixes with sizing material by all powder, depress the weight banburying again 2-3 minute, and rose weight cleaning stirring, depress weight banburying discharging after 2-3 minute again.
3, discharging, open refining: the sizing material that mixer mixing is good drops in the mill and rolls, the slit of adjusting mill is 10 ± 2mm, prolong to press and beat triangle Bao Sanci, it is once thin that the slit of adjusting mill again is that 0.5-1mm draws, and mixing adjustment mill slit, back is slice behind the 10mm.
4, slice, leave standstill: go out into the material piece first of about specification 400*400*10mm by film-discharging machine (being provided with antisticking device, refrigerating unit), material piece first cooled off, left standstill 24 hours.
5, second batch, refining: will be first material piece throw into and open refining in the mill, until the roller that touch and encase mill, press the secondary prescription again and add sulphur, promotor, whipping agent, coloring agent, mixingly draw thinly until even fully, make the sizing material sheet.
6, slice, leave standstill: by film-discharging machine the sizing material sheet is gone out into the thickness of certain regulation, leaves standstill cooling 2 hours after the slice.
7, stamping-out, sulfuration: sizing material sheet stamping-out is good, put into mould matched moulds sulfur foam.Die temperature is at 145-155 ℃, die pressure 120-130 kilogram, curing time 4-7 minute.
8, cooling, arrangement: from mould, take out the good sizing material sheet of sulfur foam, set level naturally cooling, repair deflashing.
9, leave standstill, finalize the design: the sizing material sheet of will cool off, putting in order left standstill 12 hours, entered 90-100 ℃ baking oven again, carried out typing in 35-45 minute, the lightweight modified rubber of namely producing lightweight, the comfortableization big bottom material that foams.
