METHOD OF MANUFACTURING SILICONE RUBBER MOLDINGS |
摘要 |
A method for the manufacture of silicone rubber moldings comprises the preparation of a silicone rubber composition by blending an organoperoxide having an activation energy of 25 to 41 kcal/mol into a semicurable organopolysiloxane composition whose main component is an organopolysiloxane having organoperoxide-crosslinkable functional groups. The silicone rubber composition is made into a particulate form and heated at a temperature below 100 degrees Centigrade to produce a semicured, particulate molding material which retains the activity of the organoperoxide and which contains residual crosslinkable functional groups on the organopolysiloxane. Subsequently a mold is filled with the molding material and the mold material is completely cured at a temperature of at least 100 degrees Centigrade under the application of pressure. The method is particularly useful for automatic molding methods. |
