A bonded bodyof a carbon film covered article and a rubber is formed by bonding a carbon film covered articlehaving a carbon filmformed on a surface of an articleto an unvulcanized rubberby affixing and vulcanizing. Thereby, a bonded body of rubber and, for example, metal can be provided without the need for an adhesive.

Bonded body of a carbon thin film covered article and a rubber

A hose for transporting refrigerant of the present technology includes an inner tube layer having a gas barrier layer and a rubber layer adjacent to an outer surface of the gas barrier layer. The gas barrier layer includes a polyamide resin composition obtained by blending from 0.5 to 20 parts by mass of a hydrotalcite per 100 parts by mass of a modified polyamide obtained by blending a polyamide and a carboxyl group-containing modified polyolefin. The rubber layer includes a rubber composition obtained by compounding from 1 to 15 parts by mass of an alkylphenol-formaldehyde resin per 100 parts by mass of a raw rubber. The raw rubber is at least one selected from the group consisting of a BIMS and a butyl rubber and/or a halogenated butyl rubber, which is a copolymer rubber.

Hose for transporting refrigerant

A hose for refrigerant transport use comprising an inner layer with superior deterioration resistance performance. The innermost layer comprised in the hose for refrigerant transport use of the present invention is formed using a polyamide resin composition comprising a polyamide and, per 100 parts by mass thereof, from 0.5 to 20 parts by mass of an acid acceptor.
