However, depending on the application, in addition to excellent elasticity and flexibility, oil resistance, strength, slidability, wear resistance, gas barrier properties, etc., which are generally defects of rubber, may be required. For various applications, a composite material is used in which a thin film of a thermoplastic resin or elastomer satisfying the above-mentioned properties such as oil resistance is adhered to the surface of a rubber product.

があった。In the adhesion of a general rubber product and a thermoplastic resin or elastomer, it is assumed that the polarity of the thermoplastic resin or elastomer is equal to that of the rubber product, that is, the two have an affinity. Even so, since the rubber product is a cross-linked product and has a three-dimensional molecular structure, for example, the surfaces of the rubber products can be easily bonded so that the thermoplastic resins adhere to each other by heating and melting the surfaces. It was not possible to bond the thermoplastic resin or elastomer. Therefore, conventionally, in order to bond the rubber product and the thermoplastic resin or elastomer, a chemical reaction is applied to the surface of the crosslinked rubber by applying a primer or an adhesive, or performing a pretreatment such as a halogenation treatment. It was necessary to chemically bond the rubber product and the thermoplastic resin or elastomer.

The present invention has been made to solve such problems, and easily adheres to a thermoplastic resin or elastomer without the need for applying a primer or an adhesive, or a pretreatment such as a halogenation treatment. The present invention aims to provide an adhesive rubber product which can be manufactured with a simpler bonding process and lower cost than conventional products.
