Rust-proof anticorrosion hydrophilic coating

Abstract

The invention discloses a rust-proof anticorrosion hydrophilic coating. The coating comprises the following components in parts by weight: 20-40 parts of melamine resin, 10-12 parts of aluminum phosphate, 5-7 parts of fire retardant, 5-8 parts of acrylamide, 6-12 parts of precipitated barium sulphate, 5-10 parts of carbonizing agent, 5-7 parts of cellulose and 10-15 parts of deionized water. The rust-proof anticorrosion hydrophilic coating has the advantages of being directly coated on the steel material so as to firmly attach the antirust agent to the surface of metal and isolate the metal from external air, water and corrosive media to reach the purpose of resisting rust and corrosion. The rust-proof anticorrosion hydrophilic coating can be widely used as rust-proof primer coating for various steel materials.

Description

technical field [0001] The invention relates to the field of metal surface treatment, in particular to an anti-rust and anti-corrosion hydrophilic coating for preventing metal surfaces from rusting. Background technique [0002] Iron and steel products are easily corroded in the atmospheric environment. The amount of steel lost due to corrosion every year in the world is very large. In order to solve or reduce the corrosion of steel products, various anti-corrosion measures are often adopted. One anti-corrosion measure is to cover the steel surface with a protective layer To isolate the direct contact of air and steel. Iron and steel products must remove the rust on the surface before covering the protective layer. The current rust removal methods mainly include mechanical methods and chemical methods. Mechanical methods such as manual shoveling, grinding, sandblasting, etc. have the disadvantages of high labor intensity, low efficiency, serious dust pollution, and are limi...

AI Technical Summary

Problems solved by technology

Mechanical methods such as manual shoveling, grinding, sandblasting, etc. have the disadvantages of high labor intensity, low efficiency, serious dust pollution, and are limited by the shape of components, such as edges, corners, concave corners, and rust on the inner diameter of thin tubes are difficult to clean. Utilize the chemical method of descaling agent to be the most widely used method in industry at present, the product kind of relevant iron and steel descaling agent at home and abroad is of a great variety at present, and iron and steel descaling agent is usually various acid liquids, and with sulfuric acid and hydrochloric acid composition Mainly, the existing problem is that sulfuric acid has poor dissolving ability to scale, and it needs to be carried out at high temperature, which is prone to hydrogen embrittlement, and the surface state of steel after pickling is not ideal.
