Problems solved by technology

[0002] At present, there are many fillers for the development and application of heavy-duty anti-corrosion coatings for power grid iron towers, such as heavy-duty anti-corrosion coatings filled with glass flakes. Glass flakes have many shortcomings, such as their high brittleness, poor compatibility with epoxy resin, and poor weather resistance. Difference
And some metal flake fillers, such as stainless steel flake heavy-duty anti-corrosion coatings, have improved to a certain extent in terms of brittleness, weather resistance, mechanical strength, and wear resistance, but the production process of stainless steel flakes is relatively high, resulting in high costs. , and glass flakes and stainless steel flakes can block the infiltration of corrosive media, but the infiltration time of corrosive media must be extended by increasing the thickness

Embodiment 1

[0026] Under normal temperature and pressure drying conditions, take 5 parts of basalt flakes and 5 parts of aluminum-silver paste, add 15 parts of xylene solvent and stir evenly, carry out pre-dispersion, and prepare a mixed solution of basalt scales and aluminum-silver paste for later use, and then prepare Add 15 parts of E35 epoxy resin to the mixed solution of basalt flakes and aluminum silver paste, and then add organic bentonite thickener, water-soluble organic polymer dispersant, isophorone leveling agent, silicone defoamer, 0.5 parts of benzyl alcohol film-forming aids, and stir again to obtain the component A solution. Then take 20 parts of polyamide 650, add 15 parts of xylene solvent and stir evenly to obtain the component B solution. Mix the component A solution and the component B solution according to the ratio of 4:1 to get the layered scale type heavy-duty anti-corrosion coating.

Abstract

The invention discloses a lamellar flaky heavy anti-corrosion coating and a preparation method thereof. The coating comprises the following components in parts by weight: a component A: 5-20 parts ofbasalt scales, 5-20 parts of aluminum paste, 15-40 parts of epoxy resin, 0.5-1 part of a thickener, 0.5-1 part of a dispersing agent, 0.5-1 part of a leveling agent, 0.5-1 part of an antifoaming agent, 0.5-1 part of a coalescing agent and 15-40 parts of a solvent; the component B comprises 20-40 parts of a curing agent and 15-40 parts of a solvent; wherein the weight ratio of the component A to the component B is 4:1. When a base material is coated with the coating, an external corrosive medium can corrode the base material, i.e., a labyrinth effect, only by walking over a longer path; the basalt flakes can also increase the wear resistance and the chemical stability of the coating; the aluminum paste has the properties of strong metallic luster, good heat resistance, corrosion resistanceand the like, so that the coating generates an angle-dependent different-color effect, and the combination of the basalt flakes and the aluminum paste greatly improves the performance of the coating.
