Problems solved by technology

In addition, the thickness of the coating also has a great influence on the anti-corrosion performance. Generally speaking, if the coating is thin, cracks will form in the zinc oxide, and the penetration of the electrolyte will be accelerated near the zinc oxide, so it is not conducive to anti-corrosion
At the same time, the current coatings still have the disadvantage of poor flame retardancy and heat resistance.

Abstract

The invention relates to a preparation method of flame-retardant corrosion-resistant paint containing a nano composite material. Carbon nanotube, nano perovskite oxide and a metal organic framework UIO material are jointly added into layered silicage, so that heat resistance and corrosion resistance of the paint are improved remarkably, aging time of the paint is reduced, long-time non-degradability at high temperature can be maintained, and good flame-retardant effect can be maintained.

Description

technical field [0001] The invention relates to a method for preparing a flame-retardant and corrosion-resistant coating containing nanocomposite materials, which belongs to the field of building materials. Background technique [0002] Anti-corrosion coatings are primers that provide cathodic protection and are typically applied to industrial equipment. It can protect the steel substrate and reduce the risk of corrosion. With its excellent weather resistance, solvent resistance, especially excellent corrosion resistance and self-repairing function, the coating has been widely used in heavy-duty anti-corrosion fields such as railway bridges, port terminals, and ship containers. large-scale application. [0003] Current research generally uses inorganic non-metallic corrosion inhibitors or additives to replace part of the zinc particles to improve the corrosion resistance of the coating, or to change the morphology of the zinc particles to study its impact on the corrosion o...
