Negative ion shoe material and manufacturing method thereof

The invention provides a negative ion shoe material which comprises rubber and tourmaline powder. The invention also provides a manufacturing method of the negative ion shoe material with above technical scheme. The method comprises the following steps: adding the tourmaline powder to liquid rubber, and uniformly mixing to obtain negative ion rubber; and carrying out compression molding on the negative ion rubber to obtain the negative ion shoe material. The shoe material provided in the invention comprises the rubber and the tourmaline powder, wherein the tourmaline powder which contains natural mineral matters can generate microcurrents, release negative ions and emit far infrared lights, and has good healthcare functions to human bodies. In addition, the method which allows the tourmaline powder to be added to the liquid rubber and to be uniformly distributed in the rubber avoids shedding caused by weak adhesion, so the shoe material has a lasting healthcare effect.
