Abstract

The invention discloses a wire drawing oil, and belongs to the field of lubricating oil. 2-mercaptobenzothiazole and 2-chlorohydrin as raw materials are taken as raw materials, firstly 2- hydrazinoethanol is prepared, and then the 2- hydrazinoethanol is introduced into boric acid, so that boron and nitrogen coordination structure which contains more active nitrogen elements and can form a five-membered ring or a six-membered ring in boric acid ester, the molecular chain is charged after optimization, steric hindrance becomes large, nitrogen-bearing molecular chain gets close to boron atom, andelectron is provided for boron atom lack of electron, so that the hydrolytic stability of the boron atom is improved, boric acid ester containing active elements B, S and N is absorbed onto the surface of drawing metal through physical absorption, abrasion of metal is reduced, then the boric acid ester is decomposed, the active elements are recombined to form a new chemical film, the occurrence rate of loss of the drawing metal is reduced, and the abrasion resistance is improved. The wire drawing oil solves the problems that the existing wire drawing oil is not easy in biodegradation, poor inenvironmentally friendly benefit, poor in film-forming property and difficult to achieve ideal lubrication effect.

Description

technical field [0001] The invention belongs to the field of lubricating oil, in particular to a drawing oil. Background technique [0002] The wire drawing oil is blended with high-performance vulcanized lard and sulfurized fatty acid ester as the main agent. It is used for drawing processing of copper, aluminum, stainless steel and other wire rods. Strain, improve the finish, effectively prolong the life of the mold. The wire drawing process is a kind of metal processing process. Under the action of pressure, the metal is forced to pass through the mold, the metal cross-sectional area is compressed, and the technical processing method to obtain the required cross-sectional area shape and size is called the metal wire drawing process. The selection of wire drawing oil It plays an important role. The main function of drawing oil is lubrication and cooling, so it is necessary to ensure that the drawing oil has sufficient lubricating effect. [0003] The main functions of w...
