Description

The invention relates to preservation and technological lubricants (KTSM) and is intended both for the preservation of sheet and profile hire, pipes, equipment and spare parts, and for use as a technological lubricant for blade processing and metal forming.

Known preservation oil containing molybdenum disulfide 0.24-10%, graphite 0.06-4%, modified boric acid condensation product of alkyl phenols mol. masses 900-1500, polyethylene of polyamines with 3-6 amine groups and formaldehyde 0.09-5%, glycol ether polyoxypropylene triol 0.003-1.5%, calcium sulfonate 0.12-5%, zinc dialkyldithiophosphate 0.3-12%, 1,2,3, -benzotriazole 0.006-0.5%, 4-methyl-2,6-di-tert-butylphenol 0.003-0.15%, mineral oil - up to 100% (RF patent No. 2042712, MKI C 10 M 163/700, 1995).

Known preservative oil of the following composition: lubricant 95-99.5%, including mineral oil, jet fuel, polyvinyl butyl ether and oxidized petrolatum; a mixture of essential oils of eugenol with citrol in a ratio of 1: 1 0.5-5% (RF patent No. 2029779, MKI C 10 M 169/04, 1995).

Also known preservation oil containing petrolatum 50-65%, low molecular weight polyisobutylene mol. masses 1200-2300 20-30%, high-pressure polyethylene 2-4%, antioxidant additive 0.1-0.2% and mineral oil - up to 100%. (RF patent No. 2041251, MKI C 10 M 169/04, 1995).

Known preservation oil K-17, containing 2.5% oxidized petrolatum, 1% synthetic rubber, 2.5% cyatim 339, 10% C 150 or PMS "I", 0.3% diphenylamine, 0.13% lithium battery , 40% transformer oil, up to 100% M-20 oil (Catalog-book edited by V. M. Shkolnikov, N. A. Kuznetsov "Oils produced by the enterprises of MINNEFTECHIMPROM USSR", M., TSNIITEneftekhim, 1986, S. 70 p.56).

The disadvantage of these compositions is the high viscosity, therefore, the inability to feed into the processing zone and use as technological lubricants.

The closest in technical essence and the achieved result to the claimed is the conservation oil "Rosoil-700" containing 5-7% oleic acid; 0.5-0.8% boric acid; 0.3-0.7% diethanolamine; 1.5-3% triethanolamine; 1-3% benzotriazole; 2-4% oxidized petrolatum; up to 100% industrial oil (RF patent No. 2232794 IPC ⁷ C 10 M 169 // 04 2004).

The disadvantage of this composition is the low tribotechnical characteristics and, as a consequence, insufficient technological efficiency in heavily loaded metalworking operations, such as sheet stamping, extrusion of an internal thread with a chipless tap, etc.

The task to which the invention is directed is to expand the functionality of the oil, in particular, to increase technological efficiency in metal forming operations by introducing Rosoil-26MO as extreme pressure additive (TU 0258-014-06377289-98), as well as antioxidant additives "Agidol-1" (TU 38.5901237-90) and detergent-dispersant additives "S-150" (TU 38.301-19-126-2001).

This object is achieved by the fact that the conservation and technological lubricant containing mineral oil, oxidized petrolatum, oleic acid, boric acid, diethanolamine, triethanolamine, benzotriazole, in contrast to the prototype, additionally contains Rosoil-26MO extreme pressure additive, antioxidant additive Agidol- 1 "and detergent-dispersant additive" C-150 "in the following ratio of components, wt.%:

oleic acid 5-7 boric acid 0.5-0.8 diethanolamine 0.3-0.7 triethanolamine 1,5-3 benzotriazole 1-3 oxidized petrolatum 2-4 Rosoil-26MO 6-10 Agidol-1 0.3-1 S-150 1,5-5 industrial oil up to 100

Introduction of Rosoil-26MO extreme pressure additive, which is a mixture of functional additives in mineral oil, as well as Agidol-1 antioxidant (ionol) and S-150 detergent-dispersant additive (colloidal dispersion of calcium carbonate in I-20A oil stabilized with calcium sulfonate) allows you to provide the necessary technological properties, while the effectiveness of protection against atmospheric corrosion of the material is maintained at the level of salable preservation oils. Thus, using the conservation and technological material Rosoil-710 in forming metalworking operations, the subsequent conservation operation can be excluded.

Concrete example

At a temperature of 60-70 ° C, components are sequentially fed into an industrial oil in the order of decreasing actual density. The mixture is stirred at this temperature until a homogeneous product is obtained.

The obtained preservation and technological lubricant has the characteristics given in table 1 in the following ratio of components:

oleic acid 6%, boric acid 0.5%, triethanolamine 3%, diethanolamine 0.5%, benzotriazole 2%, oxidized petrolatum 3%, anti-seize additive Rosoil-26MO 10%, antioxidant additive Agidol-1 0, 5%, detergent-dispersant additive "S-150" 4%, industrial oil I-8Am 70.5% (TU 0253-010-33818158-2000).

The data presented in table 1 show that the Rosoil-710 preservation-technological lubricant is not inferior to the prototype in terms of protection against atmospheric corrosion, while in terms of tribological and technological properties it exceeds the Rosoil-700 preservation oil selected as a prototype.
