Problems solved by technology

Organic solvent-based cleaning agents have strong cleaning performance and are easy to dry, but because their raw materials contain organic solvents and have the characteristics of fast volatilization, they are flammable and explosive, and there are great safety hazards in the process of use and storage , which is harmful to the environment and the human body; the other type is water-based cleaning agent, which uses water as the main body. Although there is no danger of flammability and explosion, it is basically alkaline or acidic It is very troublesome to deal with the waste liquid after cleaning, and has the disadvantages of high waste liquid treatment cost and difficult discharge; another type is powder type cleaning agent, which needs to be dissolved with water before use. The product has the disadvantages of uneven dissolution, unstable products and most of them contain phosphorus, which has a great impact on the environment

Abstract

The invention discloses an environment-friendly neutral aluminum alloy cleaning agent and a preparation method thereof. The environment-friendly neutral aluminum alloy cleaning agent comprises the following components in percentages by weight: 1-3% of edetate disodium, 6-10% of polyethylene oxide, 10-20% of a surfactant 502, 1-5% of silanone, 0.3-0.8% of 1, 2-benzisothiazole-3-one, 0.2-0.3% of hydrated sodium silicate, 0.1-0.3% of benzotriazoles, 0.1-0.2% of sodium citrate, 0.1-0.2% of D-sodium gluconate, 2-6% of a pH value regulator and the balance of water. The environment-friendly neutral aluminum alloy cleaning agent is harmless to the environment and human bodies; the cleaning rate is high, and cleaned products are free of undesirable phenomena such as discoloration, mildewing and white spots; foams are less during use, and the surface states of the products are observed conveniently; and the product is free of phosphorus and nitrogen and neutral in pH value, so that waste liquidtreatment is facilitated, and the treatment cost is reduced.

Description

Technical field: [0001] The invention relates to the technical field of metal cleaning agents, in particular to an environment-friendly neutral aluminum alloy cleaning agent. Background technique: [0002] In the maintenance and repair of mechanical processing, mechanical equipment, automobiles, etc., diesel oil, kerosene or gasoline are traditionally used as cleaning agents to clean parts. This type of cleaning agent not only wastes energy, but also has potential safety hazards. If you are not careful, it may cause a fire. In recent years, a new type of water-based metal cleaning agent has gradually been widely used. It can replace diesel, kerosene and gasoline to clean parts, and it is cheap and safe to use. It is very suitable for mechanized cleaning operations. It is the so-called water-based metal cleaner. [0003] Among all kinds of metal materials that need to be cleaned, aluminum alloy is a relatively active material. During processing and storage, it will be affec...
