Description

The invention relates to mechanical engineering, instrument making, agriculture; used in the restoration and repair of machines and mechanisms, assemblies in any industry.

Currently, for the preparation of parts before assembly, painting and conservation of finished products; flammable and toxic organic solvents or aqueous degreasers containing surfactants are used for cleaning and degreasing.

The closest in essence and the achieved result to the claimed is an analogue - a detergent composition for degreasing metal parts, a description of the author's certificate No. 667589, containing surfactants for cleaning metal surfaces: sodium tripolyphosphate, trisodium phosphate, soda ash, diproxamine 157, sintanol DT -7, carboxymethyl cellulose, sodium nitrite.

Known means does not clean surfaces: abrasive, salty, soot-covered, some paintwork pollution. The use of sodium nitrite sharply increases the toxicity of the detergent composition.

The technical problem lies in the absence of a detergent composition having a low toxicity class with a simultaneous increase in detergent action.

The technical result of the invention is the simultaneous provision of an increase in detergent action and a decrease in the toxicity of a technical detergent.

The technical problem is solved by the fact that the detergent composition for cleaning contaminated surfaces of machine parts and mechanisms contains sodium carboxymethyl inulin, tributyl phosphate, sodium bicarbonate, citric acid, sintanol, Trilon B, sodium laureth sulfate, sodium polyphosphate, polyanionic cellulose (CAP), glycerin, casein glue , with the following ratio of components, wt.%:

sodium carboxymethylinulin 22-26 tributyl phosphate 13-16 bicarbonate of soda 20-22 lemon acid 6-8 sintanol 6-8 trilon B 2 sodium laureth sulfate 0.5-2.5 sodium polyphosphate 2-10 polyanionic cellulose (DAC) 2-4 glycerol 0.01 casein glue 0.5-2 water rest.

The above combination achieves a technical result, which consists in simultaneously providing an increase in the washing effect and a decrease in the toxicity of a technical detergent.

For degreasing, aqueous solutions of the composition with a concentration of 4-8% are used.

When the content in the composition of sodium carboxymethylinulin is less than 22 wt.% and more than 26 wt.%, tributyl phosphate is less than 13 wt% and more than 16 wt%, sodium bicarbonate is less than 20 wt% and more than 22 wt%, citric acid is less than 6 wt% and more than 8 wt%, syntanol less than 6 wt% and more than 8 wt%, Trilon B more or less than 2 wt%, sodium laureth sulfate less than 0.5 wt% and more than 2.5 wt%, sodium polyphosphate less than 2 wt% and more than 10 wt% , polyanionic cellulose (DAC) less than 2 wt% and more than 4 wt%, glycerol more or less than 0.01 wt%, casein glue less than 0.5 wt% and more than 2 wt% properties of the composition deteriorate.

The tests of the composition were carried out at mechanical repair plants for washing the engines of agricultural machines and tractors before repair after disassembly. Long-term use of the invention-composition at these plants, where the most severe test conditions, showed the following results: it reliably cleans surfaces from oil-fat, abrasive, salt deposits and some paint and varnish contamination, promotes coagulation of washing and cleaning processing waste, contains a defoamer and corrosion inhibitor, completely fire and explosion-proof, practically does not cause dryness and redness of the skin upon contact, non-toxic, and low-foaming process wastes do not float to the surface of the container and settle in the form of sludge, facilitating recycling and creating low-waste, environmentally friendly technology in production and repair machines and devices. The technology of washing with the use of this detergent refers to energy-saving technologies, due to the fact that at a normal temperature of water T=20°C, used as a solvent for the composition, the detergent gives good results. Other known compositions and detergents require a solution temperature of T=75°C, and only then they show their cleaning ability.

Table 1 shows the composition of the proposed composition. Comparative data on testing the proposed and known compositions are shown in table 2.

The test of the composition is carried out on metal plates made of sheet steel according to GOST 0709-72, rectangular, 100x100 mm in size, not more than 2 mm thick, the washing effect and the dirt removal rate are determined using a stopwatch and weighed on a balance with an accuracy of 0.0001 g.

From the above data it follows that the composition "effect" has improved properties in comparison with the known composition.
