Abstract: The present invention provides a method of manufacturing a shoe using a multifunctional primer, comprising the steps of coating a rubber outsole made of unvulcanized rubber with a liquid multifunctional primer comprising a polyurethane dispersion, a butadiene rubber solution, and a natural rubber solution; vulcanizing the unvulcanized rubber outsole coated with the multifunctional primer, thermally activating the coated vulcanized rubber outsole; coating the thermally-activated rubber outsole with an adhesive; and attaching the rubber outsole to a variety of other parts.

Abstract: The present invention provides a multifunctional primer, comprising a first solution including 15 to 55 parts by weight of natural rubber and 750 to 1350 parts by weight of an organic solvent; a second solution from 100 parts by weight of the first solution and additionally 45 to 90 parts by weight of a polyurethane-dispersion; comprising a third solution from 100 parts by weight of the second solution and 100 to 250 parts by weight of a butadiene-based rubber solution containing 50 to 200 parts by weight of a butadiene rubber and 800 to 950 parts by weight of an organic solvent. Additionally a method of manufacturing a shoe is disclosed in an environmentally friendly manner by application of the primer to a transfer sheet, this being dried and cut into appropriate pieces, and this film-type multifunctional primer applied on a non-vulcanized outersole of a shoe.
