Problems solved by technology

[0003] However, the method of using adhesives has poor bonding force and is not resistant to acid and alkali. Generally, it is operated by spraying and coating, and cannot effectively deal with the complex 3D bonding; the method of chemical etching must be used to ensure the bonding force. Need to use concentrated acid to heat or use fluorine-containing corrosive liquid, because the heating method of concentrated acid is time-consuming, high energy consumption, and acid liquid evaporation pollutes the environment, and if fluorine-containing corrosive liquid is used, due to the high toxicity of fluorine, it is harmful to the environment. The production environment has high requirements and belongs to high-pollution and high-risk substances

Abstract

The invention discloses a metal resin complex and a preparation method thereof. The metal resin complex provided by the invention comprises a metal substrate, a resin layer, and a joint molecule located between the metal substrate and the resin layer, wherein one end of the joint molecule is bonded with the metal of the metal substrate, and the other end of the joint molecule is bonded with the resin layer; and the joint molecule is a silicon compound as shown in a general formula (1), wherein the joint molecule is bonded with the resin of the resin layer through a group R and with the metal of the metal substrate through at least a group selected from the group consisting of X1, X2 and X3. Through specific groups of the joint molecule to bond with the metal and the resin, the metal resin complex provided by the invention can effectively give play to a joint bridge of the metal and the resin, thereby being able to significantly improve binding force between the metal and the resin.

Description

technical field [0001] The invention relates to a metal-resin composite body and a preparation method thereof. Background technique [0002] At present, there are two main methods for combining the metal matrix with the resin: one is to use an adhesive to combine the two together through the action of the chemical adhesive on the metal matrix and the formed resin; Chemical etching is carried out to produce ultra-miniature concave-convex surfaces, and then combined by injection molding. [0003] However, the method of using adhesives has poor bonding force and is not resistant to acid and alkali. Generally, it is operated by spraying and coating, and cannot effectively deal with the complex 3D bonding; the method of chemical etching must be used to ensure the bonding force. Need to use concentrated acid to heat or use fluorine-containing corrosive liquid, because the heating method of concentrated acid is time-consuming, high energy consumption, and acid liquid evaporation p...
