AI Technical Summary
Technical Problem
Existing two-component self-healing anti-corrosion coatings are insufficient in their corrosion resistance and cannot effectively protect metal substrates.
Method used
By using modified graphene as an anti-corrosion filler, the compatibility between graphene and coating base material is improved through the interaction between the modifier and epoxy resin, thus preparing a two-component self-healing anti-corrosion coating with better anti-corrosion properties.
Benefits of technology
The use of modified graphene significantly improves the corrosion resistance of coatings, enabling the coating to restore its integrity and protective properties after damage or corrosion through self-healing components, thus extending the service life of materials.

Abstract
This invention relates to the field of coating technology and proposes a two-component self-healing anti-corrosion coating and its preparation method. The two-component self-healing anti-corrosion coating comprises component A and component B. Component A includes the following components: epoxy resin, anti-corrosion filler, self-healing agent, additives, and solvent. Component B includes the following components: epoxy resin curing agent. The anti-corrosion filler includes a first modified graphene and / or a second modified graphene. The modifier for the first modified graphene is a compound containing phenyl and hydroxyl groups in its molecular structure, and the modifier for the second modified graphene is a compound containing phenyl and two or more nitro groups in its molecular structure. This technical solution solves the problem of poor corrosion resistance in related two-component self-healing anti-corrosion coatings.
