The present invention also provides a kind of method of preparing above-mentioned high speed copper pipe drawing lubricating oil, in described method, according to mass percent each material of weighing, load weighted mineral oil is added in compounding kettle, stir and be warming up to 60 ~ 80 DEG C, then add high molecular polymer, to be dissolved evenly after, add successively synthetic ester, thiadiazoles derivative, benzotriazole, continue to stir 60min ~ 90min until product is uniformly dissolved, blowing, 80～100 eye mesh screens filter, pack, put in storage.
Principle of work of the present invention is: adopt refined wax base straight chain mineral oil, and synthesize ester as host through the polyvalent alcohol of organic synthesis, by adding high molecular polymer to improve oilness and the annealing cleanness of drawing copper tubes oil, to meet the lubricating requirement of copper pipe disk machine drawing high speed drawing technique, and utilize neutralization technology to solve the anticorrosive and antirust requirement of process lubrication system and parts and copper pipe.
The present invention compares with prior art, and its effect is actively with obvious.High speed copper pipe drawing lubricating oil of the present invention has the following advantages:
1) adopt the material such as high molecular polymer, synthetic ester, there is the adhesivity under better oilness and high pressure, can eliminate scratch and the defect of copper pipe surface;
2) stronger stability, the lubricated extreme pressure property of lasting performance, effectively protects mould and extends its life-span;
3) easy cleaning, noresidue after annealing, detergency is good;
4) good oxidation-resistance, avoids the variable color of copper pipe inside and outside wall;
5) poisonous and harmful product such as sulfur-bearing, nitrite, phosphorus not;
6) meet the processing requirement of plate drawing machine high speed copper pipe drawing.
