Problems solved by technology

However, most of the water-based epoxy resin coatings on the market have harsh construction conditions. The construction can only be carried out under the condition that the ambient temperature is 8°C-35°C, the humidity is <80%, and the surface temperature is 3°C higher than the dew point temperature, so it is severely limited. its application

Abstract

The present invention relates to water-based epoxy resin coating, water-based epoxy resin coating, floor and preparation method thereof, wherein the water-based epoxy resin coating comprises: A component; in parts by weight, said A component comprises: non-ionic 40-60 parts of water-based epoxy curing agent, 2-3 parts of water-based polyamide curing agent, 1.1-2 parts of auxiliary agent and 20-50 parts of powder; the hydrogen equivalent of the non-ionic water-based epoxy curing agent is 120 ‑280; the powder includes latex powder, quartz powder, wax powder, titanium dioxide and barium sulfate; and B component; in parts by weight, the B component includes: hydrogenated bisphenol A type epoxy resin 83‑ 91 parts, 3-10 parts of diluent and 1-3 parts of emulsifier. The water-based epoxy resin coating can be applied in a low temperature environment (such as about 0° C.), and the obtained coating has high wear resistance and hardness.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based epoxy resin coating, a water-based epoxy resin coating, a floor and a preparation method thereof. Background technique [0002] Epoxy resin coatings are widely used in the preparation of epoxy resin floors, especially industrial floors, due to their high hardness, good wear resistance, strong adhesion, good flexibility, and excellent chemical corrosion resistance. At present, epoxy resin floors are mainly divided into solvent-based epoxy resin floors and water-based epoxy resin floors. Among them, solvent-based epoxy resin floors contain a large amount of volatile organic solvents, which have a greater impact on the environment, so they are gradually replaced by water-based epoxy resin floors. At present, the water-based epoxy resin floors on the market are mainly prepared by mixing and proofing of curing agents, various additives and powders, and then compounded ...
