Title:
RESIN MOLDED BODY
Document Type and Number:
WIPO Patent Application WO/2017/126347
Kind Code:
A1
Abstract:
Some parts of a sealing surface (11) of a thermosetting resin member (10) are non-roughened surfaces (11b) not subjected to roughening treatment, and the remaining parts thereof are roughened surfaces (11a) recessed with steps (11c) from the non-roughened surfaces and made rougher than the non-roughened surfaces. An additive (20a) containing a functional group is added to a thermoplastic resin member, and a functional group existing at the roughened surfaces and the functional group existing in the additive are chemically bonded together. When a direction from the side of the sealing surface at a boundary with an exposed surface, toward the interior of the thermoplastic resin member is defined as a first direction (Y1), the roughened surfaces form closed annular shapes around the entire circumference of the sealing surface about an axis parallel to the first direction. At the sealing surface, three of more of the roughened surfaces forming the closed annular shapes are arranged in the first direction, spaced apart by the non-roughened surfaces.
