The present invention relates to a one-component or low-component additive in oils having a complex effect which provides a light wash and reduces the corrosion effects of the media. Naviao components can be applied practically to all kinds of machinery, especially in the engineering and metallurgy industry.

In the engineering and metallurgical industries, as well as in some other industries, oiled parts after pre-operative or inter-operative preservation prior to metal coating, heavily before any other refinement need to be thoroughly cleaned.

From the point of view of the theological flow of production, it is often necessary to preserve the blanks for storage reasons and to complete these prior to the next theological operation. Also, in the thermal treatment of metals, where the oil is smoothed, subsequent degreasing is often required. In the engineering and metallurgical industries, there are still possible operations requiring the environment of the olive and its subsequent removal.

Currently, only the most organic solvents, alkaline degreasers or mineral acids in combination and subsequent neutralization or paaivatives are used to degrease the components from the oil. Degreasing agents are also known which contain organic solvents e.g. kerosene, diesel and the like in combination with surfactants.

Recently, the development of metal parts cleaning has been solved by the addition of additives to oil oils to ensure its cleaning after the operation. E.g. AO 159 478 discloses a water-washable oil which is quenched from quenched components with water containing from 2 to 20% by weight. nonionic or anionic surfactant.

OSA patent S. 3,454,496 discloses a mazaol composition having self-reading properties. It is prepared by the reaction of the products of polyalkynyleukolimides, polyalkylaneamine and formaldohydrome and phenol. Patents are known and disclosed which address improvements in the application properties of oils, but do not improve the washability and water washability. They are eg. OSA patent no.

No. 438,897, wherein the lubricating composition has anti-corrosion properties. USSR patent S. 613 72? has an increased lubricating effect by the addition of an oxygen-containing organic compound containing sulfur in the molecule. Another USSR patent no. No. 617,018 solves the preparation of a lubricating liquid having an increased lubricating effect by the addition of phosphated organoalcoholic aromatic compounds. U.S. Pat. No. 3,909,437 discloses a composition for cleaning and degreasing metallic surfaces including, among other ingredients, soluble nonionic surfactants, characterized by a base temperature of about 32 ° C.

The drawback of the procedures used to remove oils from components is Vlaoero. When using organic solvents, these can get into the air atmosphere and endanger health. When using alkali metal degreasing agents, the bath bath must be heated, which adversely affects the energy bilano of production. Mineral acids can cause corrosion, resulting in minor non-compliance with the theological procedure. Calcium oils and the addition of surfactants above 2 wt. due to the amount of additional ingredients, the calorie properties of the oil are altered, which is disadvantageous in some cases. All of these methods require increased costs for the purification operation, in the latter case, the cost of treating the Kalia oil.

These drawbacks are eliminated by the oil additive, which also has a light wettability consisting of an alkylpyridinium halide, the alkyl having 5 to 21 carbon atoms, preferably oylpyridine bromide, and / or a mixture of surfactants of 30 to 70% by weight. % alkylpolyellyl ether in the Seobeon pattern of Η-Ο / Ο, Η Ο Ο Η / Η 70 and 30 to 70 wt. Sodium alkyl glycol ether sulphate of the formula RO / C ^H HO / ^SO SON, where n is 1 to 10, preferably 3 to 5 and R is an alkyl of 9 to 18 carbon atoms, the weight ratio of alkylpyridinium halide to the surfactant mixture is 1 with 3 to 10.

The additive according to the invention is applied for the correct function of the oil and not to change the properties of the oil in an amount of usually 0.002% by weight. % of a mixture of alkylpolyellyl ether surfactants and sodium alkylpolyglycol ether sulfate and 0.0002 wt. alkylpyridinium. The components can be used individually, optionally also in the presence of other surfactants or suitable solvents. Said components may be blended with gasoline, kerosene and / or a mixture of kerosene and gasoline prior to addition to the oil.

Among the main advantages is the fact that these ingredients are applied in very small quantities and yet have a high level of efficacy, both from the wash and the corrosion reduction. Since it is a single or low-composite additive, there is no increase in handling requirements, and preparation is simple. The greatest advantage is achieved by applications when certain operations can be eliminated and significant energy consumption is reduced, and the saving of cleaning agents with an impact on the environmental environment is also very important.

Reading the oil components by their low optimum amount of added substances according to the invention practically does not affect the cost of the oil for a given theological procedure and removes the cost of subsequent reading with organic solvents, alkaline cleaners, acids or surfactants. At the same time, it ensures higher corrosion protection of components after rinsing with water.

For your convenience, here are some examples.

Example 1

Addition of 0.001 wt. 7% by weight of surfactant mixtures. an alkylpolyglycol ether of the formula RO / C CH ^O / HH and 30% by weight of a sodium alkyl polyglycol ether sulphate of the formula RO / CgH /O / ^-SO ^Na, where n is 4 and R is an alkyl having a carbon number of 12 to 16; 0.0002 # wt. The oilylpyridinium bromide in the oily oil is reached until the bearing rings are completely clean with flowing water. Coolants for water have a stronger corrosion resistance compared to water for hardening oil without additives. Heating a cleansing bath containing a 5% aqueous solution of the composition consisting of 7 ° C. sodium silicate and ϊ 30 wt. The sodium phosphate (Alkon A) which is thus used to read the components at 90 ° C is switched off in our way, the temperature drops to 15 ° C and the alkaline degreaser (Alkou A) content is reduced to 2% by weight. This bath * serves Salei only for dopasivevanio rings, which are often spraoúvají on Salché operáell after fourteen days. The rings for degreasing already before the bath aqueous solution consist of 70% by weight. sodium silicate and 30% by weight of sodium phosphate (Alkon A) are as pure as after purification by the old theology.

Example 2

To the OK-1 preservative oil, a mixture of tonsides of composition as in Example 1 was added in an amount of 0.003% by weight, and 0.0006% by weight. % oethyl pyridine bromide and 0.06 wt. petrol. The oil is used for the interoperative preservation of components. After rinsing with a pressurized water, the pure components can be used for salvia toohnologic oporal.

Example 3

A mixture of tonsides according to the composition as in Example 1 in an amount of 0.014% by weight was added to the petroleum-supernatant blend. and 0.0018 wt.% oethylpyrldinium bromide. Superfinished bearing rings are a mixture. After rinsing with pressurized water, it is possible to dispense with the water in the bath with a 5% aqueous solution of a mixture consisting of 70% sodium silicate and 30% by weight sodium phosphate (Alkon A), 90 ° C warm and can be passivated immediately. * and the old procedure.

Example 4

To the OK-1 preservative oil as in Example 2, 0.0025 wt. % of the mixture, consisting of J 20 # wt. octylpyridinium bromide and 80 wt. laurylpyridíniumbromidu. After rinsing the components with pressurized water, the components appear clean and are suitable for the Saléie teohnolo / gioké operáole.

Example 5. /

0.02% by weight of the tonside mixtures consisted of the tonsides mentioned in Example 1, but in a composition of 50% by weight, to the superfinished mixture for the bearing rings as in Example 3. The bearing rings are flushed with only pressurized water and after this operation passivation can be carried out directly.
