Abstract

The invention relates to aqueous rusted antirust paint which is composed of, by weight parts, 60-110 of butyl acrylate, 20-60 parts of acrylonitrile, 5-12 parts of octamethylcyclotetrasiloxane, 3-8 parts of dodecafluoroethyl methacrylate, 1-4 parts of N-ethylmorpholine, 0.5-2 parts of acrylic acid, 3-6 parts of dodecylbenzenesulfonic acid, 2-4 parts of sodium dodecyl sulfate, 0.5-2 parts of ammonium persulfate, 1-5 parts of tannic acid, 2-10 parts of phosphoric acid and 180-220 parts of water. The aqueous rusted antirust paint has the advantages of fast rust conversion speed, strong adhesion,low overall cost of coating, no volatile gas generation, and environmental protection.

Description

technical field [0001] The invention belongs to water-based paint, in particular to a water-based rust-proof rust-proof paint. Background technique [0002] At present, there are many water-based rust-proof paints or coatings. Compared with solvent-based rust-proof paints, they have the advantages of simple coating process, low cost, and low organic volatile compounds (VOC), but their quality is not good or bad. First, the more prominent problem is that the VOC content of some coatings is too high, and there are still environmental pollution problems of varying degrees. [0003] The root cause of the above-mentioned high VOC content is that isopropyl alcohol is used as a solvent and dispersant in the emulsion base material. An important component of rust-proof paint or coating performance. However, isopropyl alcohol not only makes the water-based rust-proof anti-rust paint or coating produce a strong pungent odor, but also causes the VOC content of the water-based rust-pro...
