Resin composition, metal-resin composite and preparation method and use thereof, and electronic product shell

A metal-resin composite, comprising a metal substrate and a resin layer attached to at least part of a surface of the metal substrate, wherein the resin layer is formed with resin composition which comprises:

• a base resin which is at least one of a polyarylene sulfide resin, a polyether resin, and a polyester resin;
• a modified resin which has a melting point that is 3-24° C. higher than a glass transition temperature of the base resin, and presents in an amount of 1-10 parts by weight, relative to 100 parts by weight of the base resin;
• and
• a fiber.

A method for preparing a metal-resin composite, comprising:

• uniformly mixing a resin composition;
• injecting the resin composition onto a surface of a metal substrate;
• and
• molding to form a resin layer on the surface of the metal substrate, wherein the resin composition comprises:
• a base resin which is at least one of a polyarylene sulfide resin, a polyether resin, and a polyester resin;
• a modified resin which has a melting point that is 3-24° C. higher than a glass transition temperature of the base resin, and presents in an amount of 1-10 parts by weight, relative to 100 parts by weight of the base resin;
• and
• a fiber.

An electronic product shell, comprising a metal shell body and at least one resin member attached to at least a part of an inner surface or at least a part of an outer surface of the metal shell body, wherein the resin member is formed with the resin composition which comprises:

• a base resin which is at least one of a polyarylene sulfide resin, a polyether resin, and a polyester resin;
• a modified resin which has a melting point that is 3-24° C. higher than a glass transition temperature of the base resin, and presents in an amount of 1-10 parts by weight, relative to 100 parts by weight of the base resin;
• and
• a fiber.
