Slip-resistant rubber composition, outsole using the rubber composition and method of manufacturing the outsole

A slip-resistant rubber composition, comprising:

• a substrate made of rubber, about 0.2 to about 7 parts by weight of a vulcanizer, about 1 to about 10 parts by weight of glass fibers, and about 1 to about 200 parts by weight of an additive, based on 100 parts by weight of the substrate,
• wherein the additive comprises about 15 to about 25 parts by weight of a filler, about 4 to about 6 parts by weight of a softener, about 6 to about 10 parts by weight of a vulcanization accelerator, about 1 to about 2 parts by weight of an antioxidant, and about 0.5 to about 1 parts by weight of a wear inhibitor, based on 100 parts by weight of the substrate, and
• wherein the rubber comprises about 10 to about 20 wt % of natural rubber, about 40 to about 60 wt % of isoprene rubber, and about 25 to about 35 wt % of butadiene rubber, the filler comprises carbon black, the softener comprises about 70 to about 90 wt % of process oil and about 10 to about 30 wt % of stearic acid, the vulcanization accelerator comprises about 40 to about 60 wt % of zinc oxide, about 20 to about 30 wt % of polyethyleneglycol, about 4 to about 6 wt % of mercaptobenzothiazole, about 9 about 14 wt % of tetramethylthiuram monosulfide, and about 0.45 to about 0.7 wt % of dibenzothiazole disulfide, the antioxidant comprises dibutylhydroxytoluene, and the wear inhibitor comprises β-(3,4-epoxycyclohexyl) ethyltrimethoxysilane.
