Waterborne one-component modified epoxy basalt flake heavy anti-corrosion coating containing resting form epoxy hardener and preparation method thereof

Abstract

The invention relates to the technical field of anti-corrosion coating, in particular to waterborne one-component modified epoxy basalt flake heavy anti-corrosion coating containing resting form epoxyhardener and a preparation method thereof. The coating is prepared from the following components in parts by weight: 30-50 parts of modified epoxy resin containing the resting type epoxy hardener, 3-5 parts of cosolvent, 0.2-1.0 part of defoaming agent, 0.3-2 part of dispersing agent, 5-20 parts of color filling agent, 5-15 parts of anti-rust material, 15-40 parts of basalt flake, 0.1-1.0 part ofwetting agent, 0.2-1.5 parts of flash and rust resistant agent, 0.1-1.0 part of anti-settling agent, 0.1-1.0 part of leveling agent and 5-20 parts of deionized water. The coating has the advantages of high strength, good thermal resistant property, high anti-corrosion property, good permeability resistance, low thermal expansion coefficient and the like. The performance of the flake resin heavy anti-corrosion materials can be greatly improved by using basalt flake.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion coatings, in particular to a water-based one-component modified epoxy basalt flake heavy-duty anti-corrosion coating containing a latent epoxy curing agent and a preparation method thereof. Background technique [0002] Flake resin heavy-duty anti-corrosion coatings are widely used in marine engineering, chimney anti-corrosion, pipeline anti-corrosion, tunnel bridges, metallurgical industry, petrochemical and other fields, and are very important coatings. The existing scale resin heavy-duty anti-corrosion materials contain a large amount of solvents, which cause certain damage to the environment and human beings; at the same time, most of the flake resin heavy-duty anti-corrosion materials use glass flakes as anti-corrosion fillers, but glass flakes generally have high brittleness, low mechanical strength, and low thermal conductivity. Low coefficient, easy aging and falling off, etc., the ...

AI Technical Summary

Problems solved by technology

The existing scale resin heavy-duty anti-corrosion materials contain a large amount of solvents, which cause certain damage to the environment and human beings; at the same time, most of the flake resin heavy-duty anti-corrosion materials use glass flakes as anti-corrosion fillers, but glass flakes generally have high brittleness, low mechanical strength, and low thermal conductivity. Low coefficient, easy aging and falling off, etc., long-term anti-corrosion performance is not ideal

On the other hand, most of the flake coatings in the prior art are made of two-component coatings in order to ensure anti-corrosion performance, and they need to be mixed before use, which is not only very inconvenient, but also prone to errors
