Description

A silicon-containing lubricating composition with strong corrosion resistance and its preparation method and application

technical field

The invention relates to the technical field of lubricants, in particular to a silicon-containing lubricating composition with strong corrosion resistance, a preparation method and application thereof.

Background technique

Phosphating is a commonly used method for corrosion resistance. Phosphating can better form a layer of film on the surface of the wire. After phosphating, a layer of saponification is performed. The resulting phosphorus saponified film can reduce the loss of subsequent processing molds. And to avoid scratches on the wire, it is the most widely used at present, but because phosphorus saponification is a two-step process, and phosphating is acidic, saponification is alkaline, so at least one washing tank is needed after phosphating, the process is long, and the phosphorus saponification time is long .

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 of obtaining the required cross-sectional area shape and size. 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. 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 generated 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. The oil stains or impurities on the surface are completely removed; and there are many kinds of wire drawing lubricants, and their performance varies greatly. Some wire drawing lubricants will turn black, deteriorate, and stink during use.

The patent CN2016100696746 discloses a non-phosphorus and chromium-free corrosion-resistant metal surface treatment agent, the raw materials of which include nano-zirconia dispersion, propionamide, ammonium hydrogen fluoride, polyvinyl alcohol, propylene glycol, siloxane, acetic acid, tea soap element, sodium citrate, sodium alginate, sodium hydroxide, silane coupling agent KH-550, film aid, linseed oil and auxiliary agent, by using nano zirconium dioxide dispersion as the main material of the metal surface treatment agent of the present invention , then add propionamide, amine hydrogen fluoride, polyvinyl alcohol, propylene glycol, siloxane, acetic acid, tea saponin, sodium citrate, sodium alginate, sodium hydroxide, silane coupling agent KH-550, membrane aid, flax Oil and additives are used as auxiliary additives of the metal surface treatment agent described in the application, which further improves the corrosion resistance and wear resistance of the metal surface treatment agent described in the application, and the metal surface treatment agent described in the application does not contain phosphorus and chromium Elements, no pollution to the environment, good metal surface treatment effect, high efficiency and low cost. Although its metal surface treatment agent does not contain phosphorus and chromium elements, in the specific implementation, no specific corrosion resistance test results are given. , the corrosion resistance test of the wire after immersion and before drawing, the copper sulfate resistance titration time is relatively short, usually less than 50s, and the actual corrosion resistance after drawing is less than 45 days, so the treatment solution of phosphorus saponification is currently carried out, The corrosion resistance time is short, and the drawing deformation is low, which has great limitations. Therefore, for this situation, a phosphating soap body solution with strong corrosion resistance is specially developed.

In view of this problem, the present invention develops a lubricating composition and a preparation method thereof that can meet the requirements of phosphorus saponification integration, and have strong corrosion resistance and good lubricity.
