Abstract
Official abstract text for this publication.
Provided are: a metal-resin composite structure, including a surface-roughened metal member and a resin member bonded to the metal member and composed of a polyarylene sulfide resin (PAS) composition; a PAS resin composition and a resin member, for use in the metal-resin composite structure; and a method. More specifically, provided are: a PAS resin composition including a PAS resin (A) and a phenol resin (B) in an amount of 0.05 to 20 parts by mass with respect to 100 parts by mass of the resin (A); a resin member obtained by melt-molding the PAS resin composition; and a metal-resin composite structure including a surface-roughened metal member and a resin member bonded to the metal member and composed of the PAS resin composition, wherein the metal member is made of aluminum, copper, magnesium, iron, titanium or an alloy containing at least one of them; and a method for producing the same.
First claim
Opening claim text (preview).
The invention claimed is: 1. A metal-resin composite structure comprising: a surface-roughened metal member; and a resin member bonded to the metal member and composed of a polyarylene sulfide resin composition, wherein the metal member is made of aluminum, copper, magnesium, iron, titanium or an alloy containing at least one of them, the polyarylene sulfide resin composition is a molded product of a resin composition including a polyarylene sulfide resin (A) and a phenol resin (B) in an amount of 0.05 to 20 parts by mass with respect to 100 parts by mass of the polyarylene sulfide resin (A), wherein the phenol resin (B) is a novolac phenol resin which is a thermoplastic polymer having a phenol skeleton, wherein the phenol resin (B) has a hydroxyl group equivalent in a range of 80 to 200 g/equivalent, and wherein the phenol resin (B) has a softening point in a range of 98 to 180° C. 2. The metal-resin composite structure according to claim 1 , wherein the polyarylene sulfide resin composition is a melt-kneaded material. 3. The metal-resin composite structure according to claim 1 , wherein the resin member is a product obtained by melt-molding the polyarylene sulfide resin composition. 4. A method for producing a metal-resin composite structure comprising a surface-roughened metal member and a resin member bonded to the metal member and composed of a polyarylene sulfide resin composition, in which the metal member is made of aluminum, copper, magnesium, iron, titanium or an alloy containing at least one of them, the method comprising melt-molding the polyarylene sulfide resin composition including a polyarylene sulfide resin (A) and a phenol resin (B) to the metal member at a temperature equal to or higher than the melting point of the polyarylene sulfide resin (A), wherein the polyarylene sulfide resin composition is a molded product of a resin composition including a polyarylene sulfide resin (A) and a phenol resin (B) in an amount of 0.05 to 20 parts by mass with respect to 100 parts by mass of the polyarylene sulfide resin (A), wherein the phenol resin (B) is a novolac phenol resin which is a thermoplastic polymer having a phenol skeleton, wherein the phenol resin (B) has a hydroxyl group equivalent in a range of 80 to 200 g/equivalent, and wherein the phenol resin (B) has a softening point in a range of 98 to 180° C.
