PROBLEM TO BE SOLVED: To provide an adhesion-proof agent composition for unvulcanized rubber, which hardly causes dust scattering after an adhesion-proof treatment, excels in the drying property after an adhesion-proof treatment, and can impart high adhesion-proof than a conventional one.SOLUTION: The adhesion-proof agent composition for unvulcanized rubber is a composition that includes: a water-soluble polymer; an inorganic powder; a polyhydric alcohol; and a surfactant as essential components, wherein the melting point of the polyhydric alcohol is at least 40°C. Based on the total amount of the water-soluble polymer, the inorganic powder, and the surfactant, the weight ratio of the water-soluble polymer is 0.5-20 wt.%, the weight ratio of the inorganic powder is 40-90 wt.%, and the weight ratio of the polyhydric alcohol is 5-40 wt.%. The weight ratio of the surfactant is in the range of 1-9.9 pts.wt. based on 100 pts.wt. of the inorganic powder. |
