Anti-termite inorganic flake waterborne epoxy resin coating

Abstract

The invention discloses an anti-termite inorganic flake waterborne epoxy resin coating. The waterborne epoxy resin coating comprises a component A and a component B, wherein the component A comprises the following components in percentage by weight: 60%-80% of bisphenol low-molecular-weight liquid epoxy resin, 4.5%-10% of active diluent, 0.2%-1.0% of dispersing agent, 0.05%-0.1% of defoaming agent, 0.2%-0.8% of non-ionic surfactant, 0.1%-0.2% of anti-settling agent, 8%-30% of extender pigment / filler, 0.5-15% of microcapsule particle dispersion suspension aqueous emulsion containing an insecticide and 5%-20% of inorganic flake material; and the component B comprises the following components in percentage by weight: 39%-65% of modified waterborne amine curing agent, 34%-60% of water, 0.2%-0.4% of dispersing agent, 0.2%-0.5% of defoaming agent and 0.2%-0.8% of flatting agent. The waterborne epoxy resin coating disclosed by the invention has the advantages of very good waterproof and moisture-proof property and anti-termite property.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a termite-proof inorganic scale water-based epoxy resin coating. Background technique [0002] In the home improvement termite control project, the anti-termite drug is generally sprayed directly on the wall parts that may be in contact with the wood and the surface of the wooden decoration material. This method exposes the anti-termite drug to the air, which will cause the active ingredients of the drug Ineffective due to rapid volatilization, oxidative decomposition or moisture. [0003] Building floors and walls are usually made of Portland concrete or cement mortar, which will produce a large number of micropores during the solidification process, which has hydrophilic properties and is easy to absorb water and water vapor. Due to temperature changes and other reasons, water vapor molecules escape from the micropores on the building floor or wall surface to generate moistur...

AI Technical Summary

Problems solved by technology

[0005] The use of general polymer cement-based waterproof coatings does not have a good moisture-proof effect, because polymer cement-based waterproof coatings are hydrophilic building materials, and continuous pores will also be formed during the film-forming process, and the pore size distribution is generally between 5-15nm. Therefore, although it has a certain waterproof effect, it can still pass through water vapor molecules, so it does not have the effect of moisture resistance.
