Long-acting water-based rust inhibitor

Abstract

The invention discloses a long-acting water-based rust inhibitor. The long-acting water-based rust inhibitor is prepared from, by weight, 500-800 parts of industrial alcohol, 15-25 parts of an HLD-1 rust-inhibition dispersing agent, 100-140 parts of base oil, 1.5-2 parts of 2,6-di-tert-butyl-4-methyl phenol, 15-25 parts of barium dinonyl naphthalene sulfonate, 40-70 parts of water and 15-25 partsof sorbitan monooleate. The materials are added into a 2T reaction kettle to be dissolved and stirred, heating is conducted to 60 DEG C and stopped 2 hours later, then deionized water is added, and when the temperature is reduced to 30 DEG C or below, a finished product can be discharged. The long-acting water-based rust inhibitor has the advantages that the problem of damage caused by aromatic hydrocarbon gas in a solvent to the human body is thoroughly solved, the flammable and explosive danger and the damage to the environment are reduced, and the requirement that special parts must be freeof oil is met.

Description

technical field [0001] The invention belongs to the technical field of antirust agents, and in particular relates to a long-acting water-based antirust agent mainly for long-term sealing and packaging of ferrous metal casting parts and the like. Background technique [0002] Water-based anti-rust is a major problem that has plagued domestic and foreign manufacturing industries for many years. The anti-rust period of most water-based anti-rust agents is about three months, which cannot meet the anti-rust requirements of products and is extremely alkaline (based on Sodium oxide and sodium hydroxide are the main materials to increase alkalinity), pollute the environment, and are difficult to handle and discharge. Most products also use toxic and harmful sodium nitrite chemical components as anti-rust agents. The surface of the parts after anti-rust treatment Dull, and the residual surface is prone to white and yellow, which seriously affects the product quality of the machine p...
