Abstract

The invention provides a resin composition, which is used for being moulded on a metal surface by means of injection to form a metal and resin complex. The resin composition comprises a main body resin, a crystallization improver and a mineral filler, wherein the main body resin is at least one of polyamide. The resin composition provided by the invention has a more appropriate crystallization rate; the resin composition is moulded on the metal surface by means of injection to facilitate the tight combination of the resin composition and a metal and the mechanical performance is higher; and the resin composition causes little damage to machining equipment. The invention also provides a metal and resin complex prepared by using the resin composition.

Description

technical field [0001] The invention relates to a resin composition and a composite body of metal and resin obtained by using the resin composition. Background technique [0002] The integrated joining technology of metal and resin refers to injecting resin composition on the metal surface layer with ultra-fine concave-convex rough structure formed by surface treatment, so as to join metal and resin to obtain a composite body of metal and resin. The most commonly used resin composition is polyphenylene sulfide (PPS) or polybutylene terephthalate (PBT) resin composition. These two compositions have good mechanical properties and processing properties, and can meet the requirements of electronic and electrical appliances. Product strength requirements. [0003] However, the molding temperature of the PPS resin composition is high, the molding cycle is long, and it will decompose during processing to produce sulfurous acid, which seriously damages the mold screw and the mold. ...
