Description

Silicon-containing lubricating composition with high corrosion resistance, and preparation method and application thereof

Technical Field

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

Background

Phosphating is a common corrosion-resistant method, a film layer can be well generated on the surface of a wire by adopting the phosphating method, and after phosphating, the generated phosphating saponification film layer can reduce the loss of a subsequent processing die and avoid the scratch of the wire, but the application is most widely at present, because the phosphating saponification is a two-step process, the phosphating is acidic, the saponification is alkaline, at least one washing tank is also needed after the phosphating, the process is long, and the phosphating saponification time is long.

The wire drawing process is a metal working process in which a metal is forced through a die under pressure, the cross-sectional area of the metal is compressed, and a desired cross-sectional area shape and size are obtained. Factors influencing the wire stretching mainly include tensile strength and deformation degree of the wire, friction coefficient between the wire and the grinding hole, size of a wire die hole, position of the wire die and the like. At present, in the stainless steel wire drawing process, wire drawing oil is generally adopted for processing, more oil stains or impurities are generated on the surface of the wire in the stainless steel wire drawing process, the oil stains or impurities on the surface of the drawn wire cannot be completely removed by adopting single wire drawing oil, various wire drawing lubricants have large difference in use performance, and some wire drawing lubricants can turn black, deteriorate and become stink in use.

The patent CN2016100696746 discloses a phosphorus-free chromium-free corrosion-resistant metal surface treating agent, which is prepared from the following raw materials of nano zirconium dioxide dispersion liquid, acrylamide, hydrogen fluoride amine, polyvinyl alcohol, propylene glycol, siloxane, acetic acid, tea saponin, sodium citrate, sodium alginate, sodium hydroxide, silane coupling agent KH-550, film aid, linseed oil and auxiliary agent, wherein the nano zirconium dioxide dispersion liquid is used as the main material of the metal surface treating agent, then, propionamide, amine hydrogen fluoride, polyvinyl alcohol, propylene glycol, siloxane, acetic acid, tea saponin, sodium citrate, sodium alginate, sodium hydroxide, silane coupling agent KH-550, film aid, linseed oil and auxiliary agent are added as auxiliary additives of the metal surface treatment agent, so that the corrosion resistance and wear resistance of the metal surface treatment agent are further improved, the metal surface treatment agent does not contain phosphorus and chromium elements, and the metal surface treatment agent has the advantages of no pollution to the environment, good metal surface treatment effect, high efficiency and low cost. Although the metal surface treating agent does not contain phosphorus and chromium elements, in the specific embodiment, specific corrosion resistance test results are not given, the results are not verified, and through common treatment fluid for carrying out phosphorus saponification integration on the market, the corrosion resistance test before wire rod is not drawn after soaking, the titration time of copper sulfate is relatively short, usually less than 50s, and the actual corrosion resistance after drawing is less than 45 days, so that the current treatment fluid for carrying out phosphorus saponification integration has short corrosion resistance time, low drawing deformation and larger limitation. Therefore, for this situation, a phosphating soap-body fluid with high corrosion resistance is specially developed.

In view of the problems, the invention develops a lubricating composition which can meet the requirements of phosphorus saponification integration and has strong corrosion resistance and good lubricity and a preparation method thereof.

As a preferable scheme, the antirust agent is one or two of amine antirust agents and alcohol amine antirust agents.

Specifically, the amine antirust agent is any one of monoethylamine, diethyl amine and triethylamine, and the alcohol amine antirust agent is any one of monoethanolamine, diethanolamine and triethanolamine.

As a preferred embodiment of the present invention, the surfactant is yin an ionic surfactant one or two of nonionic surfactants.

Specifically, in the present application, the surfactant is mainly used to emulsify the polysiloxane polymer or urethane acrylic resin. The anionic surfactant is dispersed by an electric double layer structure to stabilize the emulsion, and the nonionic surfactant is dispersed by a hydration layer formed by shielding effect to stabilize the emulsion, so that the stability of the emulsion can be effectively increased.

In the application, the addition of carboxymethyl cellulose can effectively improve the viscosity of the silicon-containing lubricating composition. Meanwhile, because the carboxymethyl cellulose is structurally carboxylate, the carboxymethyl cellulose and silicate can have synergistic effect, can be preferentially adsorbed on wires, and plays a role in lubrication.

Specifically, in the application, the ether solvent is dipropylene glycol dimethyl ether, and the alcohol solvent is one or two of isopropanol and n-butanol.

A second object of the present application is to provide a method for preparing a silicon-containing lubricating composition having high corrosion resistance, comprising the steps of:

S1, preparing materials according to the weight parts of the raw materials of the silicon-containing lubricating composition;

s2, mixing the surfactant and the film forming agent, heating and stirring for 20-30min at the temperature of 80-90 ℃, adding a proper amount of water, and emulsifying for 0.6-1h at the stirring speed of 800-1200rpm to obtain a mixed solution A for later use;
