Abstract

The invention discloses a preparation method of a metal organic framework / water-based anti-corrosive coating. The composite coating is formed by compounding a coordination compound of a metal organic framework (MOFs) and water-borne epoxy resin. As a novel organic hybrid material, the coordination compound of a metal organic framework (MOFs) has high void ratio and adjustability of hole dimension and shape; when the material gets the outside stimulation (such as pressure, light, chemical stimulation of a guest molecule), the framework shape can be changed. The preparation method introduces the metal organic framework material to an anti-corrosive coating system, thus the crosslinking density of the coating can be added, the corrosive particles can be absorbed; besides, the preparation method overcomes the shortcoming of poor barrier property and short anti-corrosive cycle which are generally existed in the water-borne anti-corrosive coating at present, and greatly improve the anti-corrosive performance of the anti-corrosive coating.

Description

technical field

[0001] The invention relates to a preparation method of a coating, in particular to a preparation method of a metal organic framework / water-based anticorrosion coating. Background technique

[0002] Metals and their alloys are still the most important structural materials, so metal corrosion is still one of the most noticeable problems. The great harm of corrosion is not only reflected in economic losses, but also brings heavy casualties, environmental pollution, waste of resources, hinders the development of new technologies, and promotes the loss of natural resources. Therefore, taking protective measures is of great significance to economic construction. There are many ways to prevent metal corrosion, but considering the needs of economy, convenience and national economic development, coatings have become the first choice to solve corrosion problems.

[0003] In recent years, due to the restrictions on the volatilization of organic solvents by nation...
