Problems solved by technology

[0004] Glass flake coating has been widely valued and applied due to its excellent permeability, good corrosion resistance and long service life. However, the amount of glass flakes has a great influence on the shielding performance of the coating, and the multi-layer shielding effect cannot be formed when the amount is small. , which affects the resistance to medium penetration; when the amount is large, the resin will be relatively reduced, which will reduce the adhesion and mechanical strength of the coating

Abstract

The invention belongs to the field of chemical engineering coating research, and particularly relates to solvent-free epoxy glass flake paint. Calixarene molecules are grafted onto glass flakes through water-based isocyanate to modify the glass flakes, the modified glass flakes and the epoxy resin molecule structure form certain entanglement through the grafted calixarene molecules in the stirring process, and therefore the bonding force of between the glass flakes and epoxy resin is improved. Accordingly, the solvent-free epoxy glass flake paint which is environmentally friendly, resistant to corrosion, high in bonding force and good in physical performance is prepared.

Description

technical field [0001] The invention belongs to the field of chemical coating, in particular to a solvent-free epoxy glass flake paint. Background technique [0002] With the strengthening of people's awareness of environmental protection and the development of maintenance-free coating systems, long-lasting, environmentally friendly, energy-saving heavy-duty anti-corrosion coatings are increasingly used in engineering construction. However, the solvent-free heavy-duty coatings in the prior art are due to The irrationality of its formula causes some technical defects and technical problems, thus hindering its further development and application. Glass flake heavy-duty anti-corrosion paint has attracted widespread attention as a highly efficient heavy-duty anti-corrosion paint. [0003] Glass flake coating is a kind of high-efficiency anti-corrosion coating made of fine flake glass as anti-corrosion filler, and polymer resin and curing agent as binder. Widely used in metallu...
