Abstract
A metal member—polyarylene sulfide resin member complex superior in airtightness between the metal member and the polyarylene sulfide (PAS) resin member and a production method therefor, in which the complex comprises a metal member and a PAS member combined together into a one-piece shaped article by injection molding and satisfies conditions 1) and 2) as described, and the PAS resin member contains a PAS resin and a modified ethylene copolymer.
Claims10
A metal member-polyarylene sulfide resin member complex comprising a metal member and a polyarylene sulfide resin member combined together into a one-piece shaped article by injection molding, wherein (1) and (2) below are satisfied:
- (1) arithmetic mean roughness (Ra1), maximum height roughness (Rz1) and root mean square height (Rq1) of a surface of the metal member in a measurement according to JIS B 0601-2001 performed using an atomic force microscope set to a field of view range of 2 μm or a confocal laser scanning microscope,
- and arithmetic mean roughness (Ra2), maximum height roughness (Rz2) and root mean square height (Rq2) of a surface of the polyarylene sulfide resin member in a measurement according to JIS B 0601-2001 performed using an atomic force microscope set to a field of view range of 2 μm or a confocal laser scanning microscope,
- satisfy a relationship or relationships of |(Ra1−Ra2)|/(Ra1+Ra2)≤0.2, |(Rz1−Rz2)|/(Rz1+Rz2)≤0.2 and/or |(Rq1−Rq2)|/(Rq1+Rq2)≤0.2, and
- (2) the polyarylene sulfide resin member contains a polyarylene sulfide resin and a modified ethylene copolymer.
