Abstract

The invention provides a formulation and the method for preparation of a green environment-friendly water-based epoxy terrace-using coating. The green environment-friendly water-based epoxy terrace-using coating comprises the first and the second component, the constituent and weight ratio of the first component being as the following: water-based epoxy curing agent 28-32, water 10-20, defoamer 0.2-0.5, wetting agent 0.2-0.5, leveling agent 0.2-0.5, consolute agent 1-5, phthalocyanine green 3-6, ferrite yellow 4-6, titanium dioxide 1-3, blanc fixe 20-30, silicon micronized quartz powder 10-15, and talcum powder 5-8; and the constituent and weight ratio of the second component being: water-based epoxy emulsion A 15-25, water-based epoxy emulsion B 20-28, and water 1-6. The first component: the second component is 1.25: 1, homogeneously mixing them. The prepared green environment-friendly water-based epoxy terrace-using coating can ensure the lacquer film having good brightness, adhesive force, strong chemical resistance, nice environmental protection property, and low containing of VOC.

Description

technical field [0001] The invention relates to a green and environment-friendly water-based epoxy floor coating formula and a preparation method thereof. Background technique [0002] At present, traditional industrial floor coatings are basically solvent-based and solvent-free floor coatings. Among them, solvent-based floor coatings contain more organic solvents, while solvent-free floor coatings contain active diluents, which are toxic and pollute the environment. endanger human health. With the gradual improvement of people's awareness of environmental protection, many countries have promulgated environmental protection regulations to limit volatile organic solvents (VOC), so the development of coatings in the direction of water-based has become inevitable. [0003] There are Type I and Type II waterborne epoxy coatings on the market. For example, the publication number is 1415680, and the patent application titled "A Waterborne Epoxy Resin Coating and Its Preparation M...
