Abstract

Provided is a rubber laminated resin composite comprising a polyamide-based resin molded product and rubber that is vulcanization bonded to the polyamide-based resin molded product; the polyamide-based resin molded product being molded from a polyamide-based resin that is blended with 0 to 70 wt. % of a filler based on the total amount of the filler and the polyamide-based resin, and that comprises an aliphatic amine compound having an amine equivalent of 950 or less in an amount of 0.045 mmol or more, preferably 0.050 to 2.0 mmol, more preferably 0.065 to 1.5 mmol, per g of the polyamide-based resin. The rubber laminated resin composite is produced by molding a polyamide-based resin that is blended or not blended with a filler, after the addition of an aliphatic amine compound thereto, and then vulcanization bonding of fluororubber or acrylic rubber to the obtained polyamide-based resin molded product.

First claim

The invention claimed is:

1. A rubber laminated resin composite comprising a polyamide-based resin molded product and rubber that is vulcanization bonded to the polyamide-based resin molded product;
the polyamide-based resin molded product being molded from a polyamide-based resin that is blended with 15 to 50 wt. % of a filler based on the total amount of the filler and the polyamide-based resin, and which polyamide-based resin further comprises an aliphatic amine compound having an amine equivalent of 950 or less in an amount of 0.065 mmol or more per gram of the polyamide-based resin.

2. The rubber laminated resin composite according to claim 1 , wherein the polyamide-based resin is at least one member selected from polyamide 66, polyamide 6, polyamide 610, polyamide 612, polyamide 11, polyamide 12, polyamide 46, polyamide 6T/6I, polyamide 6T/66, polyamide 6T/6, and polyamide 9T.

3. The rubber laminated resin composite according to claim 1 , wherein the filler is a glass fiber or a carbon fiber.

4. The rubber laminated resin composite according to claim 1 , wherein the aliphatic amine compound has an amine equivalent of 250 or less.

5. The rubber laminated resin composite according to claim 1 , wherein the aliphatic amine compound has a boiling point of 120° C. or more.

6. The rubber laminated resin composite according to claim 1 , wherein the rubber is fluororubber or acrylic rubber.

7. A method for producing a rubber laminated resin composite, comprising:
molding a polyamide-based resin that is blended with 15 to 50 wt. % of a filler based on the total amount of the filler and the polyamide-based resin, and which polyamide-based resin further comprises an aliphatic amine compound having an amine equivalent of 950 or less in an amount of 0.065 mmol or more per gram of the polyamide-based resin; and
vulcanization bonding of rubber to the obtained polyamide-based resin molded product.

8. The rubber laminated resin composite according to claim 4 , wherein the aliphatic amine compound has a boiling point of 120° C. or more.
