The preparation method of anti-electrostatic two sulphur sponge sizing material, gets each component by above-mentioned weight fraction, 1) prepare master batch: the standard rubber of 1/2 is not plasticated to Wei Shi plasticity number 0.63 ~ 0.68 higher than on the opening rubber mixing machine of 50 DEG C in temperature, obtains rubber master batch broken-(down)rubber, rubber master batch broken-(down)rubber is added in banburying, add 2 parts of stearic acid, polyamide staple fibre and graphitized carbon blacks, refine and add high wear-resistant carbon black after 2 minutes, after re-refining 4 minutes, add machine oil, after Banbury mixer load gets up, refine after 1 minute, then add dibutyl phthalate (DBP), after rubber mixing machine load gets up, refine and within 3 minutes, make dibutyl phthalate (DBP) all be held into after in colloid, sizing material to opening rubber mixing machine, and turns refining evenly by discharge under 5 ~ 6mm roll spacing, bottom sheet, naturally cool to room temperature, place 24 hours for subsequent use, 2) broken-(down)rubber is prepared: do not plasticated to Wei Shi plasticity number 0.63 ~ 0.68 higher than on the opening rubber mixing machine of 50 DEG C in temperature by remaining standard rubber, obtain broken-(down)rubber, 3) prepare rubber unvulcanizate: by step 2) in obtained broken-(down)rubber, vulcanization accelerator, nano zine oxide, remaining stearic acid, gas generation agent H, Whitfield's ointment and sulphur drop in rubber mixing machine, refine after 1.5 minutes, add master batch, re-refine 1 minute, then potter's clay is added, refine after 4 minutes, discharge is to opening rubber mixing machine, under the roll spacing of opening rubber mixing machine is the condition of 4 ~ 5mm, by rubber unvulcanizate refining evenly, slice water cooling, detect and correct, make the sulfuration starting point of rubber unvulcanizate be 2 points 40 seconds ~ 3 points 30 seconds, plasticity number is 0.52 ~ 0.58, obtain anti-electrostatic two sulphur sponge sizing material finished product.
The application of anti-electrostatic two sulphur sponge sizing material, by anti-electrostatic two sulphur sponge sizing material slice on a mill until, slice thickness is 3 ~ 3.5mm, is cut into corresponding film by mold shape; The film cut and the glue face of base fabric in the anti-electrostatic rubber overshoes sponge cut are pasted, after metering adhesive plaster weight, by it in the two sulphur sponge mold cavities of 160 ~ 170 DEG C, cloth is faced down, glue faces up, sulfuration 3.5 ~ 4.5 minutes under pressure 20MPa condition, repaiies stream limit glue, obtains anti-electrostatic two sulphur sponge finished product.
In order to verify effect of the present invention further, carry out following experiment:
One, standard rubber broken-(down)rubber Wei Shi plasticity number is to sponge foaming influential effect
Obtained by table 1, needed for two sulphur gelatin sponge, the Wei Shi plasticity number of standard rubber is 0.63-0.68.
Two, sulfuration balanced constant is to foaming effect and resistance value influences
1, vulcanization system, hair engaging aperture system are to two sulphur sponge quality influence
2, rubber softening system, reinforcing and filling system are to sponge quality influence
By table 2, table 3, acquisition optimum formula consumption be: 100 parts of 2# standard rubbers, 2.5 parts of sulphur, 1.9 parts of vulcanization accelerators, 8 parts of nano zine oxides, 13.5 parts of stearic acid, 2.5 parts of gas generation agent H, 0.5 part of Whitfield's ointment, 90 parts of potter's clay, 20 parts of high wear-resistant carbon blacks, 5 parts of graphitized carbon blacks, 15 parts of 46# machine oil, 10 parts of dibutyl phthalates, 2 parts of polyamide staple fibres.
Three, cure conditions research:
Drawn by table 4 testing data, the optimum cure condition of anti-electrostatic two sulphur sponge is: vulcanizer operating pressure 20MPa, curing temperature 165 DEG C, curing time 3.5min.
Five, accelerator combination system is to anti-electrostatic two sulphur sponge quality influence
