Title:
METAL MEMBER–POLYARYLENE SULFIDE RESIN MEMBER COMPLEX AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/196190
Kind Code:
A1
Abstract:
Provided are: a metal member–polyarylene sulfide resin member complex (hereinafter "complex") that has excellent air-tightness between a metal member and a polyarylene sulfide resin (hereinafter "PAS resin"); and a production method therefor. The complex is an integrally injection molded product of a metal member and a PAS resin and fulfills 1) and 2). 1) The arithmetic mean roughness Ra1, the maximum height roughness Rz1, and the root mean square height Rq1, when the metal member surface is measured using an atomic force microscope or confocal microscope having a field of view range of 2 μm, and the arithmetic mean roughness Ra2, the maximum height roughness Rz2 and the root mean square height Rq2, when the PAS resin member surface is measured, fulfill ｜Ra1 – Ra2｜/(Ra1 + Ra2) ≤ 0.2,｜Rz1 – Rz2｜/(Rz1 + Rz2) ≤ 0.2 and/or ｜Rq1 – Rq2｜/(Rq1 + Rq2) ≤ 0.2. 2) The PAS resin member includes PAS resin and a modified ethylene copolymer.
