Abstract

The invention discloses environment-friendly anticorrosion double-component coating. The environment-friendly anticorrosion double-component coating comprises a component A and a component B. A mass ratio of the component A to the component B is 2:1-6:1; the component A comprises polyquaternium modified sulfonated polyether amine-hyperbranched polypyrrolone copolymers, deionized water, dimethyl sulfoxide, polyvinylidene fluoride micro-powder, titanium dioxide powder, bentonite, zirconium oxide, polyoxyethylene polyoxy-propanol amidogen ether and KH-560; the component B comprises polyisocyanate and dimethyl sulfoxide. The invention further discloses a method for preparing the environment-friendly anticorrosion double-component coating.

Description

technical field [0001] The invention belongs to the technical field of coatings, and more specifically, the invention relates to an environment-friendly corrosion-resistant two-component coating and a preparation method thereof. Background technique [0002] Two-component anti-corrosion coatings are widely used in various fields such as residences, construction plants, vehicles, ships, grain storage warehouses and petrochemical storage tanks. However, due to the limitation of product formula, the coatings currently produced have the following shortcomings: [0003] (1) The weather resistance and water resistance of the product generally cannot meet the requirements; [0004] (2) In the event of a fire, the film-forming substances of these fire-resistant coatings cannot withstand the sharply rising temperature and are quickly burned, and cannot play the role of fire prevention; [0005] (3) Poor properties such as anti-corrosion, mildew resistance, acid and alkali resistance...
