PURPOSE: A rubber composition having superior abrasion resistance for flooring, and a rubber floor material using the same are suitable for the floor material which is installed in busy places. CONSTITUTION: A rubber composition having superior abrasion resistance for flooring comprises a 100 parts by weight base resin, 150-200 parts by weight clay, a 30-70 parts by weight calcium carbonate, a 0.1-5 parts by weight cross-linking agent, a 0.1-3 parts by weight cross-linking promoter and silica. The base resin comprises a 10-80wt% styrene-butadiene rubber and a 20-90wt% butadiene rubber. The cross-linking agent is sulfur. The cross-linking promoter is one or more than two mixtures selected from a tetramethylthiuram disulfide, an N-tert-butyl-benzothiazole sulfenamide, a dipentamethylenethiuram tetrasulfide, and a dibenzothiazyl disulfide. |
