Abstract
The invention provides a novel two-component epoxy resin corrosion-resistant coating, which consists of components A and B, wherein the component A comprises the following components in parts by weight: 30 to 50 parts of epoxy resin, 20 to 40 parts of a filler, 5 to 10 parts of a diluent, 0.2 to 0.8 part of a dispersant, 15 to 25 parts of a solvent and 0.5 to 2 parts of a leveling agent; the component B comprises the following components in parts by weight: 5 to 85 parts of a curing agent and 15 to 25 parts of polyaniline; the mass ratio of the onent A to the component B is 5:1. The invention further discloses a preparation method for the two-component epoxy resin corrosion-resistant coating. The two-component epoxy resin corrosion-resistant coating has high corrosion resistance.
Description
Technical field: [0001] The invention relates to an anti-corrosion coating, in particular to a novel two-component epoxy resin anti-corrosion coating and a preparation method thereof. Background technique: [0002] Anti-corrosion coating is an indispensable coating in paint coatings. Under normal conditions, it can prevent corrosion of metals and protect the service life of non-ferrous metals. It can be used as primers for ships, containers, and automobiles. , Steel structures, bridges, metal anti-corrosion primers, oil pipe anti-corrosion coatings, etc., are widely used. The defect of the existing anti-corrosion coating is that the anti-corrosion performance is not ideal. Invention content: [0003] The technical problem to be solved by the present invention is to provide a novel two-component epoxy resin anticorrosion coating, which has very good anticorrosion performance. [0004] In order to solve the problems of the technologies described above, the technical soluti...
