[0002] Water-based anti-rust agents are widely used in the anti-rust treatment of metal surfaces. Most of the currently used metal water-based anti-rust solutions contain nitrates or nitrites. And contain a large amount of phosphorus, zinc, nickel and other elements, these substances can be converted into carcinogens or radioactive, seriously polluting the environment and endangering human health
However, anti-rust oil is used as the anti-rust agent. The oil is flammable and explosive, has poor safety performance, and the anti-rust time is short. It is only about one month under natural sunny conditions; and it is volatile and has a strong smell. It has certain hazards and is not environmentally friendly; it is very easy to absorb dust in the air when exposed to the outside, which affects the appearance and is not easy to clean. Its cost is high and uneconomical, often directly increasing the cost due to rework and scrapping

Abstract
The invention discloses a water-based antirusting agent for iron casting. The water-based antirusting agent comprises, by mass, 15-20 parts of benzotriazole, 5-8 parts of glycerol, 2-3 parts of fatty alcohol-polyoxyethylene ether, 4-5 parts of diethanol amine, 2-3 parts of ethyl maltol, 3-5 parts of a hydroxyethyl cellulose, 6-8 parts of amino silicon oil, 3-5 parts of bis(hexamethylenetriaminepenta(methylenephosphonic acid)), 2-3 parts of bis(Hexamethylene triamine penta (methylene phosphonic acid)) , 2-3 parts of potassium fluoborate, 3-4 parts of potassium fluosilicate, 2-3 parts of ammonium bifluoride, 3-4 parts of potassium fluoride, 5-6 parts of lauryl sodium sulfate, 3-5 parts of ferric sodium edelate, 2-4 parts of sodium tripolyphosphate, 3-5 parts of isothiazolinone and 100-150 parts of deionized water. Dust cannot be attached to the water-based antirusting agent for iron casting, the surface of cast iron is quiet clean, pollution to the environment is avoided, harms on an operator are avoided, waste water is easily treated, the antirusting time is long, the antirusting time can be one year at least under the natural drying ventilation condition, the water-based antirusting agent is not combustible, and the safety is high.
Description
technical field [0001] The invention relates to the technical field of antirust agents, in particular to a water-based antirust agent for cast iron. Background technique [0002] Water-based anti-rust agents are widely used in the anti-rust treatment of metal surfaces. Most of the currently used metal water-based anti-rust solutions contain nitrates or nitrites. And contain a large amount of phosphorus, zinc, nickel and other elements, these substances can be transformed into carcinogens or radioactive, seriously polluting the environment and endangering human health. However, anti-rust oil is used as the anti-rust agent. The oil is flammable and explosive, has poor safety performance, and the anti-rust time is short. It is only about one month under natural sunny conditions; and it is volatile and has a strong smell.
