た。(Prior art) Conventionally, the bonding between a fluororesin film layer and a rubber body was achieved by applying an activation treatment such as crosslinking to the surface of the fluororesin because it is chemically stable, and then bonding the rubber body with an adhesive. Vulcanized bonding with the body is performed. However, this conventional method has had the problem that the effective time of the activated portion of the rubber body is very short, so that the adhesive must be applied immediately after the activation treatment to bond the fluororesin film. For this reason, it is necessary to activate the fluororesin film only in the necessary amount each time, and there is an inconvenient problem that only the activation treatment cannot be performed in advance.

Corona discharge treatment, sodium naphthalene method, etc. , plasma oxidation method, etc. A thermoplastic synthetic resin is used as the resin adhesive for forming the polymer film. Polymerization and adhesion between the treated surface of the fluororesin film and the olefin film can be carried out by ordinary lamination processing.
Polymerization of the rubber body is carried out using a crosslinking agent without using a vulcanizing agent, and the composition of the rubber body is
A normal formulation based on EPDM etc. is applied. Molding of the rubber using a mold is carried out at a temperature approximately 20 to 50°C higher than the melting point of the olefin resin film. Molding is carried out by arranging the polymer film in a mold so that the olefin resin layer and the rubber correspond to each other, and applying heat and pressure using a press or the like to effect crosslinking. Olefin resins become more reactive with heat and adhere to rubber due to the radical reaction of the crosslinking agent in the rubber.

造法。1. When obtaining a rubber molded product in which a fluororesin film layer is bonded to the surface of a rubber body, one side of the fluororesin film forming the fluororesin film layer is subjected to an activation treatment, and the treated surface is coated with resin adhesive. Olefin-based films are laminated and bonded via an agent to form a polymerized film, and then a pre-crosslinked rubber to which a crosslinking agent has been added is supplied to the olefin-based resin film surface of the polymerized film to form a mold together with the polymerized film,
A method for producing a rubber molded product joined with a fluororesin film layer, characterized by crosslinking the rubber before crosslinking.
