Abstract

The invention discloses a two-component epoxy anticorrosive coating, and belongs to the technical field of polymer anticorrosive materials. The coating is prepared by the following steps: sequentiallyweighing the following components in parts by weight: 40-60 parts of mixed epoxy resin, 30-40 parts of a solvent, 4-8 parts of a dispersing agent, 5-8 parts of a levelling agent, 4-8 parts of a coupling agent, 10-12 parts of epoxidized soybean oil and 20-35 parts of an additive; mixing the mixed epoxy resin and the solvent in a stirrer, adding the dispersing agent, the levelling agent, the coupling agent, the epoxidized soybean oil and the additive into the stirrer, performing mixing under stirring for 30-40 minutes under the conditions that the temperature is 40-50 DEG C and the rotating speed is 300-400 r/min to obtain an A component; weighing 12-20 parts of a curing agent to obtain a B component; and separately packaging the A component and the B component to obtain the two-component epoxy anticorrosive coating. The epoxy anticorrosive coating prepared by the technical solution of the invention has the characteristic of excellent corrosion resistance, and has wide prospects in development of technical industry of high polymer anticorrosive materials.

Description

technical field [0001] The invention discloses a two-component epoxy anticorrosion coating, which belongs to the technical field of macromolecule anticorrosion materials. Background technique [0002] Solvent-based epoxy coating has good physical and chemical properties, it has excellent bonding strength to the surface of metal materials, and has excellent anti-corrosion performance. Therefore, the epoxy coating anti-corrosion system is currently recognized as the best anti-corrosion performance and the most widely used coating system. No matter in marine anti-corrosion or industrial anti-corrosion, the demand for epoxy coatings is very large. However, water-based anti-corrosion coatings have been widely concerned and applied only when the content of volatile organic compounds in coatings is limited. [0003] The anticorrosion of water-based epoxy systems mostly relies on anticorrosion fillers, but the anticorrosion fillers used are mostly zinc phosphate, aluminum tripolyph...
