Abstract

The invention relates to a cold-rolled sheet rolling emulsified oil containing a modified nano copper and preparation method thereof, which belong to the field of organic chemistry. The emulsified oil comprises the following components, in percentage by weight: 54-80% of a base oil, 15-32% of an oiliness agent, 0.1-1% of a modified nano copper particle, 2-4% of an extreme pressure agent, 0.5-2% of an anti-rusting agent, 2-6% of an emulsifier, 0.4-1% of an anti-oxidant, 0.03-0.1% of an anti-foaming agent, and 0.2-0.6% of an anti-mildew agent. The cold-rolled sheet rolling emulsified oil containing the modified nano copper is diluted with water into a 2-6 wt% emulsion, and the emulsion is directly used in the cold rolling process of the strip steel and has very good lubrication, cleaning property of the rolling mill and annealing cleaning property, after annealing, the steel plate not subjected to degreasing has a clean surface without pollutants, so as to satisfy rolling production requirement under high pressure at high speed.

Description

technical field [0001] The invention relates to an emulsified oil and a preparation method thereof, in particular to a cold-rolled sheet rolling emulsified oil containing modified nano-copper and a preparation method thereof. Background technique [0002] Cold rolling emulsified oil is a process lubricant used in the cold rolling process of steel plates. The emulsified oil is mixed with water to form an oil-in-water emulsion. The emulsion is sprayed between the roll and the rolled material at high speed, and then the oil and water are separated, and the oil droplets are adsorbed on the surface of the steel plate. This layer of oil can reduce the friction between the roll and the plate, reduce the total rolling pressure and energy consumption, increase the reduction of each pass and reduce the rollable thickness. [0003] There are many patents about rolling emulsified oil such as: CN86101764, CN1186846, CN1500854, CN1654611, CN101016498, CN1403554, CN1653166, CN1594518, CN1...
