NOVELTY - Graphene stainless steel high speed drawing lubricating oil comprises 62-73 wt.% base oil, 3-10 wt.% extreme pressure antiwear agent, 4-12 wt.% 170 # chlorinated paraffin, 0.5-2 wt.% anticorrosion agent, 2-5 wt.% polyol ester, 0.5-1 wt.% antioxidant, 1-5 wt.% viscosity index improver, 0.2-1 wt.% rust inhibitor, 0.2-1 wt.% defoamer, and 0.5-2 wt.% graphene modified binary compound additive. USE - Graphene stainless steel high speed drawing lubricating oil. ADVANTAGE - The graphene stainless steel pipe highspeed drawing lubricating oil has better lubricity and adhesion under high speed and high pressure drawing; it can eliminate the scratch and corrosion defect on the surface of the stainless steel pipe; the surface finish of the stainless steel pipe is higher; at the same time, the lubricating oil has stronger stability, it can permanently exert lubricating extreme pressure performance, protect the stretching mold and has self-repairing function to the stretching mold, it greatly prolongs the service life of the mold; in the stretching process, there is no toxic and smell-free smoke gas, the production process is more environmentally-friendly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the high-speed drawing lubricating oil of graphene stainless steel tube comprising (a) taking base oil, extreme pressure antiwear agent, 170# chlorinated paraffin, anticorrosion agent, polyol ester, antioxidant, viscosity index improver, rust inhibitor, defoamer, graphene modified binary compound additive, the base oil is composed of 500SN and 150bs, and the mass ratio of 500SN and 150bs is 55:45, (b) injecting the 150bs base oil into the oil mixing tank, heating up the temperature to 45-60℃, at the same time starting the impeller stirrer, stirring at a constant speed, the stirring speed is 30-50 revolution/minute, and allowing to stand for 5-10 minutes after the temperature reaches, (c) adding extreme pressure antiwear agent, 170# chlorinated paraffin, polyol ester, and viscosity index improver to the base oil, and stirring at 45-60℃, in the impeller stirrer at a constant speed, the stirring speed is 50-80 revolution/minute, and the stirring time is 40-60 minutes, and fully dissolving the additives, (d) adding anti-corrosion agent, anti-foaming agent, antioxidant and anti-foaming agent to the oil dissolved in the above step (c), heating up the temperature to 60-80℃, open the air compression stirrer during the adding process, stirring at a uniform speed, the compressed air pressure is 1.2-1.6 atmospheric pressure, and the stirring time is 30-50 minutes, until the above additives are fully dissolved, and allowing to stand at a constant temperature for 10-15 minutes, (e) adding 500SN to the dissolved oil, during the adding process, turning on the impeller stirrer and stirring at a constant speed, the stirring speed is 40-60 revolution/minute, the stirring time is 40-60 minutes, and controlling the temperature at 50-80℃, stirring the lubricating oil evenly, cooling down the temperature to 30-45℃, (f) adding the graphene-modified binary compound additive to the dissolved oil, during the adding process, turning on the air compression stirrer and stirring at a constant speed, and the air compression air pressure is 1.2-1.6 atmospheric pressure, the stirring time for 60-80 minutes, until the above graphene-modified binary compound additive is fully and uniformly dissolved into the lubricating oil solution, and allowing to stand at a constant temperature for 10-15 minutes, and (g) after the process of step (f) is completed, the preparation of the high-speed drawing lubricating oil for the graphene stainless steel tube is completed, and sampling and testing the indicators of the drawing lubricating oil, and qualifying the inspection, directly loading into barrels and storing in storage.
