Abstract

The invention discloses a waterborne multifunctional coating and a preparation method thereof, relating to the field of coatings. The invention provides the waterborne multifunctional coating which comprises the following components in parts by weight: 80-120 parts of water, 8-12 parts of propylene glycol, 1-2 parts of a wetting dispersant, 5-10 parts of a dispersant, 5-8 parts of a multifunctional auxiliary agent, 2-4 parts of a defoaming agent, 1-2 parts of a preservative bactericide, 150-200 parts of rutile type titanium dioxide, 30-100 parts of an antirust pigment, 500-650 parts of waterborne acrylic emulsion, 50-70 parts of a film coalescing aid, 10-20 parts of wax emulsion, 10-30 parts of a flash rust remover, 5-10 parts of a hydrophobic modified alkali swelling thickening agent and 5-10 parts of a polyurethane type thickening agent. The waterborne multifunctional coating prepared by the method disclosed by the invention has the advantages of being non-toxic, harmless, pollution-free, high in hardness and the like.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a water-based multifunctional coating and a preparation method thereof. Background technique [0002] The pollution caused by volatile organic compounds (VOC) released during the production and use of traditional solvent-based paints is currently listed as the main source of urban pollution after cars. As people are concerned about environmental issues, they also pay more and more attention to the pollution and toxicity of coatings. Countries around the world have successively promulgated relevant laws and regulations, which put forward strict requirements for the environmental protection of coatings. [0003] However, the current traditional coatings have disadvantages such as high VOC content, pollution, and low hardness. Contents of the invention [0004] In order to solve the problems existing in the prior art, the present invention provides a water-based multifunction...
