Preparation method of aluminum alloy resin composite body and aluminum alloy resin composite body

Abstract

The invention discloses a preparation method of an aluminum alloy resin composite body. The preparation method comprises the following steps: S1. carrying out anodic oxidation on a pre-treated aluminum alloy base material to obtain an aluminum alloy base material with a nano micro-pore in the surface; S2. mixing strong-alkaline waste liquid and strong-alkaline wastewater sediment, which are generated by an alkali corrosion groove in a pre-treatment process of the step S1 with a sodium acetate solution to form a mixed solution; and S3. putting the aluminum alloy base material into the mixed solution, and further corroding so as to form a corroded hole in the surface of the aluminum alloy base material. The invention further discloses the aluminum alloy resin composite body. Aiming at the problems that the application of a previous resin combining body is limited, the bonding force is poor, the structure strength requirements of a product cannot be met and the like, the corroded hole with a relatively large hole diameter is formed by corroding the nano micro-pore for multiple times, and the aluminum alloy resin composite body with the high bonding force and good structure strength is prepared; and a chemical recovery process is adopted so that the environment-friendly and pollution-free effects are achieved in the preparation process, and the industrialized production and environmental protection are facilitated.
