Abstract
A chopping board of the present invention is formed in a manner that synthetic rubber (NBR) and hard chloroethene as a basis are kneaded into a mixture wherein an anti-bacterial agent is mixed. Definitely, a stiffening agent of synthetic rubber, low-pressure polyethylene resin, white carbon black which is the reinforcing extender of rubber, zinc flower as a reinforcing accelerator of rubber, titanium as a coloring agent and stearic acid as a dispersion accelerator are mixed with the base of synthetic rubber(NBR) and hard chloroethene. The mixture thus obtained is agitated under kneading by a kneader exclusively for rubber and then a ceramic power and an inorganic anti bacterial agent are mixed with the kneaded mixture so as to mold the chopping board.
