Problems solved by technology

But at present, due to the relatively immature technology of water-based environmental protection coatings, if there is no guarantee of good formula and good construction technology conditions, it is easy to cause short-term coating aging and peeling off, and cannot protect the substrate very well.

Abstract

The invention discloses an aqueous environmentally-friendly coating. The coating comprises, by weight, 91-100 parts of an aqueous acrylic emulsion, 1-2 parts of polydicyclopentadiene, 0.5-1 part of ammonium molybdate, 0.1-0.2 parts of iron trifluoroacetylacetonate, 1-2 parts of polypropylene glycol, 1-2 parts of potassium silicate, 2-4 parts of octyl epoxy stearate, 0.5-1 part of 2-mercaptobenzimidazole, 10-12 parts of ultrafine barium sulfate, 2-3 parts of polymethyl acrylate, 0.3-1 part of lauryl dimethyl amine oxide, 2-4 parts of a flame retardation assistant, 2-3 parts of ethylene glycol butyl ether and 20-30 parts of deionized water. Compared with solvent-based coatings, the coating disclosed in the invention has the advantages of environmental protection, low volatility, good resistance of the surface of a coating layer, good stability, certain flame retardation effect and security improvement.

Description

technical field [0001] The invention mainly relates to the field of coatings, in particular to a water-based environmental protection coating. Background technique [0002] With the deepening of air pollution prevention and control, the pollution control of the paint industry is also quietly unfolding. At present, it is developing in the direction of water-based environmental protection coatings, powder coatings, and high-solid coatings. Among them, water-based environmental protection coatings are developing more rapidly. Water-soluble coatings have the advantages of non-toxic, environmentally friendly, odorless, low volatility, non-flammable and non-explosive, and high safety. But at present, due to the relatively immature technology of water-based environmental protection coatings, if there is no guarantee of good formula and good construction technology conditions, it is easy to cause short-term coating aging and peeling off, and cannot protect the substrate very well. ...
