STATIC ELECTRICITY DISSIPATING RESIN HOSE

WIPO Patent Application WO/2017/141901

A1

A static electricity dissipating resin hose according to the present invention is characterized by being configured from an inner layer that makes contact with fluid, an intermediate layer comprising two layers that are a first intermediate layer and a second intermediate layer, a reinforcing layer, and an outer layer, wherein: the inner layer is formed of a chemical-resistant resin and a conductive substance; the first intermediate layer is formed of a conductive substance and a resin having fusibility with respect to the inner layer and the second intermediate layer; the second intermediate layer is formed of a conductive substance and a resin having fusibility with respect to the first intermediate layer and the outer layer; the reinforcing layer provided between the second intermediate layer and the outer layer includes at least conductive fiber or a metal wire; and the outer layer is formed of a thermoplastic resin or elastomer. Accordingly, provided is a static electricity dissipating resin hose which has a good neutralization and is capable of safely removing static electricity generated by, for example, friction between fluid and the inner layer of the hose, which is free from risk of damage due to the influence of stray current, and which has less fluctuation in terminal-to-terminal resistance even when the length used is increased.
