Abstract

The invention discloses a waterborne epoxy floor level coating and a preparation method thereof. The coating comprises a waterborne epoxy seal primer, a waterborne epoxy floor level intermediate coat and waterborne epoxy floor level coating finish, wherein the primer, the intermediate coat and the finish are same in component A which comprises 85-95 parts of liquid epoxy resin and 5-15 parts of an epoxy active diluent; the components B are different according to different characteristics of the primer, the intermediate coat and the finish but the main components consist of a waterborne epoxy curing agent and tap water. The waterborne epoxy floor level coating disclosed by the invention is environment-friendly, low in VOC content, good in wear-resisting property, high in hardness and excellent in chemical corrosion-resisting property.

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to water-based epoxy floor coatings and a preparation method thereof. Background technique [0002] Epoxy resin coatings are widely used in the coating of industrial floor coatings due to their high hardness, good wear resistance, strong adhesion, good flexibility, and excellent chemical corrosion resistance. At present, my country's industrial floor coatings mainly use solvent-based epoxy floor coatings and solvent-free epoxy floor coatings. Solvent-based epoxy floor coatings contain a large amount of volatile organic solvents. The solvent-free system uses epoxy reactive diluents. Although epoxy reactive diluents can participate in the reaction, they are still toxic and costly. [0003] In recent years, with the promulgation of various laws and regulations on environmental protection, the problem of environmental pollution has attracted great attention from the society. It is a maj...
