  • Patent number: 9566767
    Abstract: A resin-rubber composite in which a low-pressure plasma-treated polyamide-based resin-molded product and a polyol-vulcanizable fluororubber composition that forms a fluororubber layer are directly bonded by vulcanization without interposing an adhesive. The low-pressure plasma treatment of the polyamide-based resin-molded product is performed in the presence of an inert gas, such as He gas, Ar gas, or N2 gas, at a pressure of 10 to 1,000 Pa. Here, an alkoxysilane compound is an optional component in the fluororubber composition, and the presence or absence of this compound does not affect the adhesion.
