step 1) weighing the raw materials for standby according to parts by weight, wherein: 100 parts of neoprene, 10 parts of phenolic resin, 8 parts of urea-formaldehyde resin, 5 parts of zeolite powder, 4 parts of dimethyl silicone oil, 3 parts of polyethylene wax, 2 parts of glass fiber, 2 parts of maleic anhydride, 1 part of talcum powder, 0.5 part of vulcanizing agent and 0.5 part of anti-aging agent;
step 2) placing zeolite powder into a heating furnace for high-temperature calcination, wherein the temperature in the heating furnace is 600 ℃, the calcination time is 15min, taking out, cooling to room temperature, then adding into hydrochloric acid solution with the concentration of 2M, which is twice the weight, soaking for 60min, centrifuging, collecting precipitate, and drying to obtain modified zeolite powder;
step 3) mixing chloroprene rubber, phenolic resin, urea resin, dimethyl silicone oil and polyethylene wax, and adding into an internal mixer for internal mixing at the temperature of 85 ℃ for 30min to obtain a main material;
and 4) uniformly mixing the modified zeolite powder, the main material obtained in the step 3), glass fiber, maleic anhydride, talcum powder, a vulcanizing agent and an anti-aging agent, discharging into a double-screw extruder, extruding to a molten state, conveying to a forming machine, and forming, sizing, traction and cutting to obtain the modified zeolite.
