PROBLEM TO BE SOLVED: To provide a method for molding a silicone rubber which is free from the occurrence of a bleeding phenomenon and can prepare a multilayered pattern. SOLUTION: In the step 1, a mold 10 with a recessed part of the mold inside is prepared. The recessed part of the mold is formed of at least one pattern layer, and a base bottom layer positioned above the one pattern layer. In the step 2, a liquid sulfurated silicone rubber 24 at room temperature is allowed to flow on the pattern layer of the mold 10. In the step 3, an initial sulfurated molding is advanced by heating a sulfurated silicone rubber 24 at room temperature. In the step 4, the surface of the sulfurated silicone rubber 24 at room temperature is coated with a surface treating agent. In the step 5, the sulfurated silicone rubber 32 at a high temperature is placed on a base bottom layer of the mold 10. In the step 6, the sulfurated silicone rubber 24 at room temperature and the sulfurated silicone rubber 32 at high temperature are thermally compressed. In the step 7, the mold 10 is opened, to complete a product of the silicone rubber. COPYRIGHT: (C)2007,JPO&INPIT |
