An anti-virus chopping board made of thermoplastic polyurethane and a method for producing the same are provided to remove bad smell from the board and to increase anti-bacteria and sterilization effects by mixing and drying colloidal silver nano and the thermoplastic polyurethane. An anti-virus chopping board(20) made of thermoplastic polyurethane contains a chain extender of molecular weight of 60 to 400, a hard part yielded by reacting diisocyanate and a UV stabilizer, a polyurethane obtained by reacting a soft part which is yielded by reacting polyols of 600 to 4,000 and diisocyanate, and colloidal silver nano. A weight ratio of the polyols and the chain extender is 1:0.05 to 1:0.1. A recessed part(22) and a bulged part(21) are formed on the anti-virus chopping board. |
