Cleaning liquid capable of preventing steel from being corroded

Abstract

The invention discloses cleaning liquid capable of preventing steel from being corroded, which is prepared from the following raw materials in parts by weight: 2.7 to 5.3 parts of hydroxyethylidene diphosphonic acid, 4.2 to 5.6 parts of active alumina powder, 5.2 to 7.6 parts of ethylene diamine disuccinic acid, 5.4 to 7.6 parts of 2-acrylamide, 3.5 to 5.6 parts of phosphate ester salts, 3.2 to 5.6 parts of glycerol monooleate hexamer and 5.6 to 7.3 parts of a corrosion inhibitor. The cleaning liquid not only has the cleaning ability, but also is corrosion inhibitors capable of preventing the corrosion of steel. An experiment shows that the cleaning agent has good anti-corrosion performance for steel, copper, aluminum, tin and alloys thereof; the cleaning ability is improved since activated alumina powder and ethylenediamine disuccinic acid are added. The cleaning liquid has good scavenging effect on difficultly washed oil dirt and polymers dirt particularly; the cleaning agent can be prepared at room temperature so that the energy is saved and the operation is easy.

Description

technical field [0001] The invention relates to a cleaning solution for preventing iron and steel from rusting, belonging to the field of chemical products. Background technique [0002] At present, industrial cleaning in my country still uses mixed hydrocarbons such as gasoline, kerosene and a small amount of water-based cleaning agents. Using gasoline, kerosene and other mixed hydrocarbon cleaning agents not only wastes a lot of energy and causes environmental pollution, but also the cleaning workers are prone to poisoning, and are very prone to fire and cause major economic losses. If half of the gasoline and kerosene mixed cleaning agents are replaced by water-based cleaning agents, the annual supply gap of water-based cleaning agents is about 200,000 tons. The use of water-based cleaning agents can save energy, reduce production costs, reduce environmental pollution, be safe and fire-proof, and gradually realize the great dream of replacing oil with water, which has br...
