The present invention provides a method for manufacturing injection-molded rubber boots, comprising the steps of: heating a polymer substrate, resulted from mixing an ethylene copolymer, having a melting point of at least 50°C, with natural rubber, to the melting point or more, and applying shearing force to form a mixture; adding a vulcanizing agent to the mixture and performing a reaction to form a final mixture; crushing the final mixture to form a crushed material; extruding the crushed material to produce pellets; and inputting the pellets into an injection molder where boots molds are mounted and performing an injection operation. |
