However, barium, lead and other harmful substances in traditional anti-rust oils will have adverse effects on human health during preparation and use, and traditional anti-rust oils have poor stability and can only be used for temporary anti-rust and anti-rust. The rust cycle is short, so a green and stable metal rust inhibitor is needed

Abstract
The invention mainly relates to the technical field of chemical industry and discloses a green and environment-friendly metal rust inhibitor. The green and environment-friendly metal rust inhibitor is prepared from the following raw materials: wool grease, oleic acid, carboxymethylcellulose sodium, polyvinyl alcohol, sodium hexametaphosphate, fatty alcohol polyoxyethylene ether, sulfamic acid, glycolic acid, L-sodium lactate and water. The green and environment-friendly metal rust inhibitor is green and environmental-friendly, is safe and healthy, has biodegradability and can be self-degraded in soil within 15 months; health of human bodies are not damaged in preparation and utilization processes and the rust inhibition period reaches 5.5 years so that the service life of metal is prolonged for 10.3 percent; a plurality of types of raw materials belong to a food grade and are safe and non-toxic; waste liquid generated after the green and environment-friendly metal rust inhibitor is used does not cause environment pollution and can be biologically degraded; the L-sodium lactate can increase the weather resistance of the rust inhibitor, the shelf life is prolonged and the economic income is improved by 12.7 percent; the rust inhibitor is convenient to use and can be directly wiped; stains on a metal surface can be removed, color and luster are increased and rusting is prevented so that the service life of the metal is prolonged.
Description
technical field [0001] The invention mainly relates to the technical field of chemical industry, in particular to a green and environment-friendly metal antirust agent. Background technique [0002] Corrosion is one of the main forms of damage to metal products. According to statistics, the annual direct economic loss caused by metal corrosion accounts for about 2%-4% of the total output value of the national economy. In order to avoid corrosion and reduce losses, people have adopted various methods. Various methods, using anti-rust agents to protect metal products, is one of the most common protection methods at present. However, barium, lead and other harmful substances in traditional anti-rust oils will have adverse effects on human health during preparation and use, and traditional anti-rust oils have poor stability and can only be used for temporary anti-rust and anti-rust. The rust cycle is short, so a metal rust inhibitor with green environmental protection and good ...
