Abstract
PURPOSE:To eliminate the corrosion or contamination of a mold and the appearance inferiority of a rubber molded product accompanied thereby, by applying a powder or emulsion composition containing one of basic metal oxide and hydroxide as an essential component as a release agent to the surface of an unvulcanized molded product composed of a fire retardant rubber composition before performing molding. CONSTITUTION:In molding a fire retardant rubber composition containing chlorinated paraffin, a release agent containing at least one of basic metal oxide and/or hydroxide as an essential component is applied to the surface of an unvulcanized molded product composed of fire retardant rubber composition. As the basic metal oxide being the essential component of the release agent, zinc oxide (ZnO) is most pref. with due regard to an aspect not curing the surface of the rubber composition and an aspect generating no change in the physical properties of rubber. The amount of chlorinated paraffin compounded with the flame retardant rubber composition to be used is at least 3%, pref., 5-20wt.% of the fire retardant rubber composition from an aspect imparting fire retardant property to said composition.
