Problems solved by technology

At present, the drawing lubricating coolant for copper-clad aluminum bimetallic rods uses oil-based lubricants, but the formed lubricating film has poor adhesion and is easy to be squeezed out during the drawing process, so that the drawn wire is drawn after repeated drawing. , the friction coefficient between the surface of the drawn wire and the edge of the hole core increases sharply, which not only causes the surface of the drawn workpiece to oxidize and discolor, and the smoothness and brightness decrease sharply, but also aggravates the wear and tear on the mold and affects the service life of the mold; in addition, there are The problem of unsatisfactory cleaning performance is not only easy to stick a large amount of metal powder on the surface of the drawn wire and the edge of the hole core during the drawing process, resulting in a further increase in the friction coefficient between the two, but also to the after-drawing of the metal wire. Process heat treatment and annealing quality will have adverse effects,

Abstract

A dual-metal rod pulling lube cooling oil of copper aluminum-coated consists of motor oil 20-30wt%, oleic acid 8-9wt%, tritolyl phosphate 20-30wt%, benamide azole trinitride 0.8-0.9wt%, anhydrous alcohol 1-2wt%, sulfur-phosphorus butanoctyl-zinc salt 20-30wt%, poly-n-butyl vinyl ether 13.5-14.5wt% and bactericide 0.2-0.3wt%. The process is carried out by dissolving benamide azole trinitride by anhydrous alcohol, adding motor oil into reactor, heating to 80-90degree, adding into tritolyl phosphate and oleic acid successively, agitating at 550-650 / min for 0.5-1.5hrs, lowering temperature to 40-50degree, adding benamide azole trinitride ethanol solution and bactericide into mixed solution, agitating for 0.5-1.5hrs, cooling, adding into sulfur-phosphorus butanoctyl-zinc salt and poly-n-butyl vinyl ether successively and agitating at 25-35 / min for 0.5-1.5hrs. It has excellent finish degree and brightness.

Description

Technical field: [0001] The invention relates to a lubricating cooling liquid for drawing process and a production method thereof, in particular to a copper-clad aluminum bimetallic rod drawing lubricating cooling which can prevent oxidation and discoloration of the finished product of the drawn bimetallic rod and ensure surface smoothness and high brightness. Oils and methods of production. Background technique: [0002] The drawing process is a typical metal processing method. It is a plastic processing process that reduces the cross-sectional area of ​​the metal processing material through the die hole core under the action of drawing to obtain a high-precision, high-gloss wire or pipe. During the drawing process, due to the large amount of metal deformation and the continuous generation of new friction surfaces, lubricating coolant is required to lubricate and cool the metal material and mold. Especially for the drawing process of copper-clad aluminum bimetallic rods, t...
