Problems solved by technology

[0002] Nowadays, the traditional anti-corrosion coatings contain heavy metal compounds, which are harmful to the environment and the human body, and are gradually discontinued; but now most of the anti-corrosion coatings are based on environmentally friendly chlorinated rubber modified resins. The corrosion performance and wear resistance are weak, which can no longer meet the new standards and requirements in the anti-corrosion market; curr

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a modified epoxy resin coating. Background technique [0002] Nowadays, the traditional anti-corrosion coatings contain heavy metal compounds, which are harmful to the environment and the human body, and are gradually discontinued; and now most of the anti-corrosion coatings are based on environmentally friendly chlorinated rubber modified resins. The corrosion performance and wear resistance are weak, which can no longer meet the new standards and requirements in the anti-corrosion market; currently, epoxy resin anti-corrosion coatings occupy an important position in the anti-corrosion field. Epoxy resin itself is thermoplastic and its molecular weight is not high. It must be cross-linked with a curing agent to form a network-like macromolecule in order to show the advantages of epoxy resin and form an excellent coating; but the current epoxy resin coating Adhesion and flexibi...
