Molybdenum disulfide-added stainless steel wire drawing liquid with good lubricity and preparation method thereof

Abstract

The invention discloses a molybdenum disulfide-added stainless steel wire drawing liquid with good lubricity, which comprises the following raw materials by weight: 2-3 parts of molybdenum disulfide, 2.5-4 parts of cerium tetrafluoride, 1-2 parts of cobaltous naphthenate, 4-5.5 parts of fatty alcohol polyoxyethylene ether, 3-4 parts of glycol, 2.5-3.5 parts of citric acid, 3-5 parts of sorbitan mo-nooleate, 1-2 parts of lead naphthenate, 3.5-4.5 parts of vulcanized whale oil, 3-4 parts of bobbin oil, 5-7 parts of auxiliary agent and 900-950 parts of deionized water. The added molybdenum disulfide as a lubrication additive is mixed with a surfactant through grinding, powder has the advantages of uniform dispersion as well as stable and uniform quality, and the added auxiliary agent has good antiwear, dispersion, lubrication and film forming ability. The employed aqueous formula has good heat radiation and cleaning performance, the wire drawing liquid has advantages of good lubrication performance, low flow viscosity, good fluidity and stability, and low cost, and is suitable for wire drawing of the stainless steel.

Description

technical field [0001] The invention relates to the technical field of wire drawing, in particular to a stainless steel wire drawing liquid with good lubricity added with molybdenum disulfide and a preparation method thereof. Background technique [0002] The wire drawing process is a 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 factors that affect the tensile strength of the wire mainly include the tensile strength and deformation degree of the wire, the friction coefficient between the wire and the grinding hole, the size of the die hole of the wire die, and the position of the wire die. Of course, the choice of drawing fluid also plays an important role. [0003] At present, in the stainless steel wire drawing process, wire drawing...

Problems solved by technology

[0003] At present, in the stainless steel wire drawing process, wire drawing oil is usually used for processing. Since more oil stains or impurities will be produced on the surface of the wire rod during the drawing process of stainless steel wire rods, the use of a single wire drawing oil cannot guarantee the quality of the wire rod after drawing. To completely remove oil stains or impurities on the surface, it is necessary to choose a water-soluble wire drawing liquid with good cleaning performance, and to ensure that the water-based wire drawing liquid has good lubricity
