Abstract

The invention discloses an electrostatic painting antirust oil to solve the problem of plain carbon steel surface erosion, which is characterized by the following: this product is composed by 70.0-90.0 mass percent base oil, 5.0-29.0 mass percent antirust agent, 0.1-5.0 mass percent atomized property improver and 0.1-5.0 mass percent antioxidant. This invention possesses merits of low cost, high flash point, good washable and lower interfacial force.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment, and relates to an electrostatic spray antirust oil for common carbon steel plate sealing. Background technique [0002] With the rapid development of modern machinery, national defense, automobile manufacturing and other industries, the demand for sheet metal is increasing, and the requirements for the surface quality of the sheet are also increasing. An important link in the storage process. In terms of steel plate rust prevention, sealing the steel plate with anti-rust oil as a temporary protection is an ideal and effective protection method. Early steel plate anti-rust oil coating method is roller oiling. Roller oiling is to apply oil directly to the surface of the strip through felt rollers. Its disadvantages are high oil consumption and uneven oiling, which can easily cause local corrosion of the steel plate. In order to solve the problem of steel plate corrosion caused by...
