Abstract

The invention provides a coating combination which comprises a coupling agent, a flatting agent, a defoaming agent, a solvent and a poly ether ketone quaternary copolymer. The poly ether ketone quaternary copolymer comprises repetitive units indicated in the formula of 101 and the formula of 102, and the repetitive units indicated in the formula of 101 and the formula of 102 are in the mass ratio of 0.01-100 to 1. The poly ether ketone quaternary copolymer is taken as a base material in the coating combination, and the coating combination is obtained by further adding proper additives; the poly ether ketone quaternary copolymer is characterized in that nitrogen containing groups of a benzene and imidazole structure, a carbazole structure and the like are introduced in the main chain of poly ether nitrile ketone, the chain structure of the poly ether nitrile ketone is changed, and adhesive force of the coating combination to metal is improved through interaction force between lone-pair electrons and a metallic matrix on N.

Description

technical field [0001] The invention belongs to the technical field of macromolecules, and in particular relates to a coating composition and a metal material. Background technique [0002] Phenolphthalein polyaryletherketone (PEK-C) is an amorphous polyaryletherketone resin obtained by polycondensation of phenolphthalein and dihalogenated benzophenone.
