Electrostatic DOS (dioctyl sebacate) oil spraying method

The invention provides an electrostatic DOS (dioctyl sebacate) oil coating method. The electrostatic DOS oil spraying method includes spraying out compressed air, atomizing DOS oil to form tiny oil particles under effects of jetting negative pressure of the compressed air and leading the tiny oil particles to move under effects of secondary airflow; ionizing the tiny oil particles to lead the tiny oil particles to have positive charge and obtaining tiny charged oil particles; and delivering the tiny charged oil particles to a place nearby a surface of a grounded aluminum plate, leading the tiny charged oil particles to move and be uniformly absorbed on the surface of the aluminum plate located at a high-voltage electric field under effects of the high-voltage electric field, and accordingly achieving the purpose of coating the DOS oil on the surface of the aluminum plate. The electrostatic DOS oil spraying method is applied to a DOS oil coating work procedure in belt production, the content, the chemical ingr
