Abstract

The invention provides a resin composition used for forming a complex of a metal and a resin through the injection molding to the surface of the metal. The resin composition comprises 40-90% by mass of a main body resin, 5-30% by mass of a crystallization alleviating agent, and 0-40% by mass of a mineral filler, wherein the main body resin comprises one or more of polyethylene glycol terephthalate and its derivatives. The resin composition has the advantages of high shearing strength, low crystallization temperature and suitable crystallization rate, so the injection molding of the resin composition to the surface of the metal is helpful for the tight combination of the resin composition with the metal, thereby the mechanical strength of the complex is high; and the resin composition has small damages to processing equipment.

Description

technical field [0001] The present invention relates to a resin composition, in particular to a resin composition for manufacturing a metal-plastic composite. Background technique [0002] The integrated bonding technology of metal and resin refers to injecting a resin composition into a metal surface layer with an ultra-fine uneven rough structure formed by surface treatment, so as to join metal and resin to obtain a composite body of metal and resin. At present, the most commonly used resins in integrated manufacturing technology are polyphenylene sulfide (PPS) or polybutylene terephthalate (PBT) resin compositions, which have good mechanical properties and The processing performance can meet the strength requirements of electronic and electrical products. [0003] However, the PPS resin composition has high molding temperature, long molding cycle and decomposes to generate sulfurous acid during processing, which seriously damages the mold screw and mold. However, the cr...
