Abstract

The invention belongs to the technical field of preparation of environment-friendly coatings and particularly relates to a waterborne epoxy flooring coating with corrosion-resisting and antibacterialfunctions and a preparation method of the waterborne epoxy flooring coating. The waterborne epoxy flooring coating is prepared from the following components: epoxy resin, trimethylolpropane, polyesterglycol 400, polyether diol 1000, ethylene glycol monomethyl ether, potassium persulfate, diethanolamine, ethanoic acid, water, filler, quartz powder, nano-aluminum powder, an antibacterial agent, a dispersing agent, a defoaming agent and a waterborne epoxy curing agent. The coating prepared by the preparation method disclosed by the invention has the advantages of excellent antibacterial property, good surface fouling resistance and good water resistance; by adding the soft segment polyether glycol and the hard segment polyester glycol, the regulation of the hardness of the coating is achieved. By adding the nano-aluminum powder, the filler and nano titanium dioxide, the capillary action can be reduced, the density of the coating is improved and the infiltration of water is reduced, so that the coating has excellent corrosion resistance and anti-fouling performance.

Description

technical field [0001] The invention belongs to the technical field of preparation of environment-friendly coatings, and in particular relates to a water-based epoxy floor coating with antiseptic and antibacterial functions and a preparation method thereof. Background technique [0002] Coatings belong to organic chemical polymer materials, and the formed coating film belongs to the type of polymer compounds. According to the classification of modern chemical products, coatings belong to fine chemical products. Modern coatings are gradually becoming a class of multifunctional engineering materials and an important industry in the chemical industry. There are four main functions: protection, decoration, concealing product defects and other special functions, and enhancing the value of the product. [0003] Epoxy coatings are adhesive materials with excellent mechanical properties, anti-corrosion properties, adhesion and chemical stability, and are widely used in anti-corros...
