Steel surface treatment paint

Abstract

The invention discloses a steel surface treatment paint which comprises the following raw material ingredients in parts: 3-5 parts of phenyl hydroxide, 20-22 parts of epoxy resin, 18-20 parts of polyester resin, 12-15 parts of rosin resin, 10-12 parts of terpene resin, 8-10 parts of alkyd resin, 10-12 parts of amino resin, 15-18 parts of acrylic resin, 5-6 parts of a lacquer thinner, 8-10 parts of organosilicon oil, 5-8 parts of glycerine, 3-5 parts of ethyl acetate, 5-6 parts of activated zinc oxide, 5-6 parts of fast-dissolving sodium silicate, 3-6 parts of dimethyl malonate, 3-5 parts of glycidyl methacrylate, 5-8 parts of ferric hydroxide, 2-3 parts of polyvinyl alcohol, 20-25 parts of vinyl acetate-acrylic emulsion and 20-30 parts of acrylic emulsion. The steel surface treatment paint mainly plays a wetting and permeating effect on loose rust to separate and wrap the rust to prevent further development of rusting; meanwhile, after forming a film, the paint interacts with the rust by virtue of slow hydrolysis to form an acid complex to achieve the purpose of rust removal; the paint has stable properties, and increases the density of the paint film to prevent permeation of water and oxygen in air.

Description

technical field [0001] The invention relates to the technical field of a steel surface treatment paint, in particular to a steel surface treatment paint that can directly remove and prevent rust, and can be used as a primer or configured as a top coat. Background technique [0002] Traditional antirust paints, including new paint, maintenance and repainting must require excellent surface treatment, that is, the rust on the steel surface is removed by manual, mechanical or pickling methods, and the cost of surface treatment generally accounts for the total cost of the painting project. About 45% of the price, it takes a lot of labor and economic costs. For some large-scale projects, such as bridges, ships, etc., the construction period is long, and even if the steel is primed, the paint film is often damaged and re-rusted. It is very difficult to carry out overall on-site surface treatment for such a large project. Contents of the invention [0003] The purpose of the pres...
