Environment-friendly water-based metal anti-rust paint

Abstract

The invention discloses environment-friendly water-based metal anti-rust paint. The paint is prepared from, by weight, 20-30 parts of water-based alcohol acid emulsion, 5-10 parts of carbomer resin, 3-10 parts of polyurethane, 1-2 parts of potassium oleate, 2-4 parts of sodium citrate, 0.5-1 part of sulfonated lignin, 1-3 parts of sodium cocoate, 1-2 parts of laurinol ammonium sulfate, 10-20 parts of inorganic filler, 1-2 parts of modifier, 2-8 parts of other auxiliaries and 10-20 parts of water. Through reasonable matching of the raw materials, the long-lasting environment-friendly water-based metal anti-rust paint which is high in adhesive force, drying speed and heat resistance, environmentally friendly and free of pollution is obtained; by adding the inorganic filler and the modifier to adjust and modify an anti-rust paint system, the superior properties of high polymer materials are improved, the corrosion resistance of the product is improved, and rust protection lasting time is prolonged; furthermore, the preparing method is simple, low in cost and suitable for large-scale production.

Description

technical field [0001] The invention relates to an antirust paint, in particular to an environment-friendly water-based metal antirust paint. Background technique [0002] In the process of production, processing and transportation of metal processing parts, it is easy to rust due to electrochemical corrosion on the metal surface after contact with oxygen, moisture or other corrosive media in the air, which requires the use of anti-rust products on the metal surface A film is formed on the surface to prevent oxygen and water from acting on the metal surface to form a mixture of oxides and hydroxides, thereby preventing metal corrosion. And anti-rust paint is exactly such a kind of product, specifically, anti-rust paint is a kind of coating that can protect metal surface from the chemical or electrochemical corrosion of atmosphere, seawater etc., and can form and store on the surface of metal parts A dense paint film can inhibit the corrosion caused by moisture, oxygen and o...

Problems solved by technology

Existing anti-rust products often have a greater poisonous effect on the environment due to the addition of oil-soluble anti-rust paint, and due to the use of volatile solvents, the anti-rust cycle of anti-rust products is shorter, and better anti-rust effects are obtained. In some cases, anti-rust products need to be coated frequently, and the anti-rust efficiency is low
