Description

 The invention relates to water-borne (water-soluble, water-emulsifiable or water-dispersible) protective lubricants.

A large number of water-borne emulsols and concentrates of SOTS are known, containing petroleum or synthetic sodium sulfonates, mineral oils, oleic acid or synthetic fatty acids of various fractions, sodium nitrite, nonionic surfactant polyglycols, neonols, laprols, syntanols, water, etc. . (NGL-205, NGL-205R, Ukrinol-1,3, Ukrinol-11, Akvol-6, Autocat, etc.) [1]
The presence of sulfonates and oils in many SOTS leads to their rapid defeat by bacteria, to the smell of hydrogen sulfide, the need for frequent replacement of SOTS, the difficulty of their disposal, etc. as well as sodium nitrite, as a corrosion inhibitor, ultimately leads to the formation of microorganisms, polychlorodiphenyls, polychlorodibenzodioxins, nitrosamines. Dioxins and nitrosamines are highly toxic, carcinogens with poor biodegradability, the ability to accumulate in the body, cause acute poisoning, cancer, skin dermatitis, etc.

 Therefore, the leading companies in the world producing SOTS (Castrol, Hoechst Germany, Esso, Shell USA, England, etc.) are developing and introducing new types of SOTS under the slogan: "without sulfonates, without oil, without chlorine, without sodium nitrite."

For comparative tests, a concentrate of reduced composition was prepared. The disadvantage of this product is the presence of carcinogenic sodium nitrite and deficient glycerol, as well as low anticorrosive and protective effectiveness.

 The objective of the invention is the creation of a water-borne inhibited protective lubricant, giving opalescent colloidal solutions in water that do not contain mineral oil, sulfonates, organochlorines and sodium nitrite, based on domestic raw materials of Russia.

The task is achieved by creating a concentrate of protective lubricant of the following composition, wt. Triethanolamine 0.5-5.0
Dioxane alcohols (oxalis) 1.0-5.0
Boric esters of dioxane alcohols 20-30

As a bactericidal additives, the polysept (metacid) polyhexamethylene guanide hydrochloride and other known bactericidal additives Vazin TU 6094735-80, Formacid TU 6-095064-83, Kamtsid TU 38.101.1081-86, Tetratsid TU 6-09-5281-86 and others were tested .

Dioxane alcohols (oxalis) wastes from the production of isoprene rubbers TU 38.103429-83. They contain triols (C ₆ H ₁₄ O ₃ ), 2,6-dihydropyranes and other compounds.

 A mixture of triethanolamine, dioxane alcohols, bactericidal additives, dyes, perfumes thus represents the basic composition that is part of the known analogues.

Distinctive components of this patent are: boric esters of dioxane alcohols 20-30% of the composition without water. Boric esters dioxane alcohols obtained by esterification of boric acid with alcohols dioxane by conventional technology (mixing temperature 80-105 ^{° C,} removing water). The main products of esterification are borates. The molecular weight of the esters is 370-380, the oxygen content is 30-35%, the density is 1.146-1.147 g / cm ³ , the refractive index is n _D ²⁰ 1.4720-1.4723.

Instead of the obtained boric esters of dioxane alcohols, it is possible to use ready-made boric esters of the product "AQUABOR" TU 301-03-119-92. According to the specified TU "AQUABOR" contains up to 30 wt. water at a content of boron is not less than 2.3% and a kinematic viscosity at 20 C ^of not more than 3.0.

 Soap stocks TU 10-0402-80-91, 10-30 wt. per composition excluding water to the main active component. Soap stocks are waste products from the production of oil and fat plants, resulting from the refining of vegetable oils of sunflower, soybean, rapeseed, coreandra, cotton, etc. and animal fats. Soap stocks are a ointment-like water-fat composition with a pH of 7-9, consisting of 50 wt. water and 50 wt. fat base: 25 wt. glycerides and 25 wt. saturated and unsaturated fatty acid soaps.

The products of the interaction of triethanolamine with monoalkyl (C ₁₀ -C ₂₀ ) phosphoric and / or dialkyl (C ₈ -C ₁₀ ) phosphoric acids and with maleic acid monoester, or with dibenzyl, were used as distinctive components acting as corrosion inhibitors, antifriction and antiwear additives. - or alkenyl succinic anhydride, or dialkyldithiophosphoric acid, or its zinc salt, or with hydroxyethylene diphosphonic acid and zinc sulfate. The product of the interaction of maleic anhydride with ethoxylated alkyl phenols neonol AF 9/12 TU 38.105.625-87 or with ethoxylated alcohols syntanol DS-10 TU 6-14-577-88 is used as a monoester. The complexes are obtained by the interaction of the components at a temperature of 60-100 ^about C, stirring 2-4 hours

 Technology for the preparation of a concentrate of protective lubricant.

 The technology is carried out in three stages on the example of the preparation of the DAF complex.

 1. Preparation of the DAF complex.

In the apparatus with a stirrer and a jacket was charged with 500 liter of 96 kg neonol AF 9/12 and 13 kg of maleic anhydride, the mixture was heated to 60-80 ^C with stirring for one hour. Then, 44 kg of dialkylphosphoric acid is added to it and after 30-40 minutes 47 kg of triethanolamine are added. 200 kg of a DAP complex of average molecular weight 1326 are obtained.

2. 320 kg of dioxane alcohols and 50 kg of boric acid are loaded into an apparatus with a stirring mechanism and a 1000-liter jacket. The mixture was heated for 4 hours to a temperature of 90-100 ° ^C. As a result of the esterification is obtained 370 kg of a mixture: dioxane alcohols excess of about 10 kg, boric esters dioxane alcohols, and 300 kg of water of about 60 kg.

3. In apparatus with a stirrer mechanism and a jacketed 2000 liter volume with stirring at 50-80 ^{° C} was charged with 200 kg of the complex of the first DAP stirrer, 10 kg of dioxane alcohols, esters of boric 300 kg of dioxane alcohols, whereupon stirring was charged with 200 kg of soapstock . After 20-30 minutes, 20 kg of triethanolamine and 40 kg of an aqueous solution of methacide are added with the addition of 0.1 kg of perfume and 0.1 kg of dye. After stirring for 1 hour, the finished product in an amount of 1000 kg is poured into a container and analyzed for compliance with TU.

 Examples of the prescription composition of the concentrate protective lubricant are presented in table. 1.

 Comparative tests of the analogue, commercial product Aquahone and concentrate protective lubricant are presented in table. 2.

 The tests were carried out in the same (typical concentration of 5 wt. Product for “hard water” according to GOST 6243-75 by standardized and research methods. As can be seen from the data in Table 2, the composition of the protective lubricant concentrate proposed in this patent exceeds the selected analogues, especially on anticorrosive and protective properties.

The generalized test results on the machines (stands) and in the production environment of the protective lubricant concentrate showed that it can be used as:
oil-free, universal, working preservation lubricant-cooling technological means (SOST) in a concentration of 3-10 wt. water for metal cutting by operations: turning, drilling, milling, grinding, honing and subsequent conservation of metal products for the interoperation period;
additives to the existing assortment of water-borne SOTS directly at metal processing plants at a concentration of 10-20% to improve their quality;
use in a concentration of 20-100 in some metal forming operations;
use in a concentration of 0.1-5 wt. in water as a detergent-preservation fluid in machine-building plants, as well as in car and agricultural equipment care;
use as a detergent-disinfectant (MDS) or as the main component of MDS in metallurgical and machine-building plants for washing and disinfecting storage systems, supply and circulation of COTS, hydraulic systems, disposal systems, etc.

 Machine-bench and full-scale tests of all the claimed compositions confirm their advantages over analogues and the versatility of their applications.
