METHOD FOR PREPARING ANTI-CORROSIVE OIL FOR COLD-ROLLED CARBON STEEL SHEETS CAPABLE OF IMPROVING DEGREASING PROPERTY

摘要

PURPOSE: Provided is an anti-corrosive oil composition for cold-rolled carbon steel sheets, which does not generate active metal oxides due to the lack of reactivity to metals, and improves degreasing property. CONSTITUTION: The anti-corrosive oil composition for cold-rolled carbon steel panels comprises 70-90 parts by weight of mineral oil, 3-15 parts by weight of barium sulfonate and calcium sulfonate, 3-10 parts by weight of a sulfur-based extreme pressure agent, and 0.1-5 parts by weight of an acrylate copolymer. The anti-corrosive oil composition is applied to a thickness of 0.5-4 micrometers on the wet thickness basis, and has a dynamic viscosity(at 40 deg.C) of 8-15 cSt.
