Abstract

Nano modified epoxy antiseptic paint is prepared by the following raw materials in weight parts: 25-35 parts of epoxy resin, 0.5-1 part of coupling agent, 20-22 parts of pigment, 20-23 parts of filler, 10-15 parts of nano silicon, and 8-12 parts of solution. As the raw materials are adopted by the nano modified epoxy antiseptic paint, during the film-forming process, the nano silicon can automatically enters generated cavities, as a result, the compactness and impermeability effects are achieved at last, the penetration resistance to water and other media is improved, and further, the antiseptic performance of the whole paint film is improved, and the extraordinary technical effect is achieved.

Description

technical field [0001] The invention relates to anticorrosion paint, in particular to a nano-modified epoxy anticorrosion paint. Background technique [0002] At present, epoxy anti-corrosion paint is suitable for water-resistant, oil-resistant and chemical-resistant reagents of steel equipment and pipelines. However, the existing epoxy anti-corrosion paint has strong anti-rust ability, is prone to precipitation, and requires high construction technology. If the construction is improper, the anti-rust pigment will not be fully utilized, the anodic protection effect will be weak, and the paint film will easily appear rust phenomenon, which will affect the long-term anti-corrosion performance of epoxy anti-corrosion paint. How to improve the long-term anti-corrosion performance of epoxy anti-corrosion paint is the direction of epoxy anti-corrosion paint. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a nano-modi...
