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 invention relates to a water-borne epoxy resin coating, a water-borne epoxy resin coating layer, a floor and a preparation method of the water-borne epoxy resin coating layer. Thewater-borne epoxy resin coating comprises a component A and a component B, wherein the component A comprises the following components in parts by weight: 40-60 parts of a nonionic waterborne epoxy curing agent, 2-3 parts of a waterborne polyamide curing agent, 1.1-2 parts of an auxiliary agent and 20-50 parts of powder; the hydrogen equivalent of the nonionic waterborne epoxy curing agent is 120 to 280; the powder comprises latex powder, quartz powder, wax powder, titanium dioxide and barium sulfate; and the component B comprises the following components in parts by weight: 83-91 parts of hydrogenated bisphenol A type epoxy resin, 3-10 parts of a diluent and 1-3 parts of an emulsifier. The water-borne epoxy resin coating can be constructed in a low-temperature environment (such as about 0 DEG C), and a coating obtained through construction has high wear resistance and hardness.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to water-based epoxy resin coatings, water-based epoxy resin coatings, floors and preparation methods 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 floor on the market is mainly prepared by mixing and proofing curing agent, various additives and powder, and then compounded with 128 ep...
