HOSE FOR TRANSPORTING REFRIGERANT |
摘要 |
<p>With the objective of providing a hose for transporting refrigerant in which a resin layer and a rubber layer can be bonded directly without pretreatment prior to adhesion on the resin layer and/or the rubber layer and which has superior adhesion between a gas barrier layer and the rubber layer, the present invention provides a hose for transporting refrigerant including an inner tube layer having a gas barrier layer and a rubber layer adjacent to the outer surface of the gas barrier layer. The gas barrier layer is formed using a thermoplastic resin composition comprising a polyamide resin (A) and a modified rubber (B) having an acid anhydride group or an epoxy group, the modified rubber (B) being obtained by modifying a modified raw rubber having an acid anhydride group or an epoxy group with a hydrogen bond-forming compound (C) having a functional group which reacts with the acid anhydride group or the epoxy group and a functional group which is able to form a hydrogen bond with an amide bond or a hydroxyl group. The rubber layer is formed using a rubber composition comprising from 1 to 15 parts by mass of an alkylphenol-formaldehyde resin per 100 parts by mass of a raw rubber. The raw rubber comprises 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. The raw rubber and/or the alkylphenol-formaldehyde resin has a halogen. There is no adhesive layer between the gas barrier layer and the rubber layer.</p> |
