NOVELTY - Process for manufacturing high-strength military boots involves (a) manufacturing of the lower layer of the sole by (A1) mixing PVC, nitrile butadiene rubber and chloroprene rubber in an internal mixer, softening, adding e.g. active agent, antioxidant and composite modified nano graphite oxide material, mixing and cooling to obtain pre-plasticized material, (A2) mixing the pre-plasticized material, accelerator and vulcanizing agent in an open mill and heating the rubber material to obtain a plastic sheet and (A3) adding the plastic sheet to the mold, adding the steel plate and pressing to form the plastic sheet to obtain the lower layer of sole, (b) mixing thermoplastic elastomer and naphthenic oil to obtain low-hardness elastomer, heating and kneading e.g. the low-hardness elastomer and chlorinated polyethylene to obtain an elastomer mother liquid, foaming, and molding to obtain middle layer of sole, and (c) gluing the upper and sole, pressurizing and stitching into finished shoes. USE - The process is useful for manufacturing high-strength military boots. ADVANTAGE - The boot has improved sole strength, is not easy to break and light weight, has wear resistance, high toughness and strong shock absorption performance, and improves shoe's performance comfort, breathability and health effects. DETAILED DESCRIPTION - Process for manufacturing high-strength military boots involves (a) manufacturing of the lower layer of the sole by (A1) adding PVC, nitrile butadiene rubber and chloroprene rubber into an internal mixer for mixing, softening, adding active agent, antioxidant, PVC resin, ethylene-vinyl acetate copolymer, plasticizer, composite modified nano graphite oxide material, mixing until evenly dispersed, discharging the formed sheet and cooling for 24 hours to obtain pre-plasticized material, (A2) mixing the pre-plasticized material, accelerator, and vulcanizing agent into an open mill, and heating the rubber material in the open mill to soften the roll to obtain a plastic sheet and (A3) adding the obtained plastic sheet into the mold at 120-130 degrees C, adding the steel plate in the mold and place the steel plate in the middle of the bottom layer of the finally obtained shoe sole and pressing to form the plastic sheet to obtain the lower layer of the sole, (b) mixing thermoplastic elastomer and naphthenic oil to obtain low-hardness elastomer, heating and kneading the low-hardness elastomer, chlorinated polyethylene, paper mulberry bark extract, ethylene-vinyl acetate copolymer, binder, plasticizer, foaming agent and activator to obtain an elastomer mother liquid, which is transferred to the foaming tooling for foaming, placing the resulting rubber above the lower layer of the shoe sole and pressurizing to obtain a foamed material and molding it to obtain a middle layer of a sole, and (c) gluing the upper and sole, pressurizing and stitching into finished shoes.
