Abstract

The invention relates to a water-soluble anticorrosive coating. The raw materials of the water-soluble anticorrosive coating consist of the following components in percentage by weight: 36 to 47 percent of water-soluble acrylic resin, 0.5 to 0.9 percent of oligomeric silicon resin, 13 to 20 percent of sodium citrate, 10 to 15 percent of zinc sulfate, and 8 to 10 percent of enhancer which is subjected to surface treatment by coupling agent dehydrated glycerol ether trimethoxy silane, wherein the mass ratio of glass micro beads to nano-alumina is 1:5; and the coating also comprises an auxiliary material part consisting of a dispersant, a lubricating agent, a defoaming agent, a surfactant and a biological preservative. The water-soluble anticorrosive coating provided by the invention has the total volatile organic compound value of 0 g / l and the formaldehyde emission of 0 g / l; and the water-soluble anticorrosive coating takes one or more of essential oil and tea polyphenol as the biological preservative, is high in uniformity, stability and strength, environment-friendly and has a good anticorrosive effect.

Description

technical field [0001] The invention relates to a coating, in particular to a water-soluble anticorrosion coating and a preparation method thereof, belonging to the technical field of chemical coatings. Background technique [0002] Household decoration pollution refers to the pollution released by various building materials and decorative materials during the decoration process, as well as the chemicals used in large quantities such as pesticides, deodorants, and fragrances, which cause pollution to the indoor environment. People spend 80-90% of their time studying, working and living indoors. "Indoor air pollution" has been paid more and more attention by people, and paint pollution is the chief culprit of indoor environmental pollution. Materials whose surfaces bond well to other materials and form a solid, tough protective film are called coatings. Coating and paint are the same concept in architecture. Coatings currently on the market are mainly divided into water-bas...
