Description

trim or chrome chips (leather production).

The content of peptides is 40-45%.

Protein hydrolyzate promotes mg; to the effect on paint and polymer surfaces and does not irritate human skin.

A feature of its use. In the composition is that it gives the tool easy and complete biological degradability. Therefore, such Prigodio detergent is widely used in service stations without building special treatment facilities.

K and N ala t a m - it is recommended to use BIBO iB iB detergent composition to give it such properties, to remove the surface tackiness after washing, to increase the gloss, to reduce the viscosity of the composition.

Polyacrylamide (prevents stains on paintwork 1M and polymer coatings after washing, reduces the viscosity of a detergent diluted with water and when used on automatic washing equipment improves the permeability of the aqueous solution through the nozzles, increases the speed of the car's exterior cleaning And gives the detergent composition " skolkost.In addition, 1 polyamide, present in the composition of the product, has the ability to hold dirt in the detergent (solution in a weighted and state.

Urea, and the use of p and l and o and p and r t, 9 t and l n g and k about l - hydrotrope substances: va - are introduced into the composition to improve the effectiveness of the washing effect, and it is for the solubility of the active base of the agent, for the creation of homogeneity, stability during storage, especially at low temperatures, for reducing the viscosity of the composition, and the point of melting of the agent.

As an odorant, acetic acid isoamyl ester is used to give the composition a pleasant smell.

A mixture of synthetic fatty acid with tributyl phosphate - (1: 1) affects the nature of foaming, inhibits it, the foam is unstable, increases the gloss of the paintwork and polymer surface, gives the water-repellent properties of the composition.

An example of the preparation of the proposed composition

200 kg of one stripped off protein hydrolyzate with a specific gravity of 1.16-1.118 ejCM is loaded into the reactor, heated to 60-70 ° C, and a pre-prepared solution of poly-1 Chrylamide (10 kg of poly-Chrylamide and 66 kg of water) is charged with stirring.

Then load 30 kg of urea. The resulting mixture is stirred for 1 hour, then 500 kg of alkyl sulfonate is charged, the mixture is stirred until complete dissolution and

70 kg of ethylene glycol, 10 kg of caprolactam and 10 kg of defoamer are loaded one by one. First load 5 kg of synthetic fatty acids, and then 5 kg of tributyl phosphate.

After stirring until homogeneous, the contents of the reactor are cooled to 35–40 °, 100 kg of isopropyl alcohol and 4 kg of acetic acid isoamyl ester are poured. The contents of the reactor are mixed again, then allowed to stand for 1 day and filtered through a filter press.

To compare the proposed and known compositions, the washing effect is measured.

In tab. 1 The data on increasing the gloss of paint and varnish paint, measured on a FB-2 gloss meter, is given.

Table 1

In tab. 2 shows the data, but for which (it is possible to judge the cleanliness of the washed surface, based on the loss of whiteness of the tissue, installed with the aid of a leukometer “Karl Zeisse.

table 2

The proposed detergent has no corrosive effect. It is completely non-aggressive with respect to any parts of the car, and does not have a negative effect on the top layer of paint.

The agent quickly dissolves in cold and hot water, forming homogeneous compositions, does not leave stains on the surfaces, and is easily washed off.

Formula (Inventions

Detergent for cleaning paint and polymer surfaces, containing water, surface-active substance, perfume, characterized in that, in order to increase the washing effect, its composition as a surfactant (introduced alkyl sulfate sodium and additionally introduced the product of hydrolysis of protein-containing materials –– molecules with a weight of 300–900, isopropyl alcohol, ethylene glycol, caprolactam, polyacrylamide, urea, and a mixture of synthetic fatty acids of the Su-Ci6 fraction with tributylphosphato-ed taken in a ratio of 1: 1 The following ratio of components, wt.%: Alkyl € ulf sodium, hydrolysis product of protein-containing materials with a molecular weight of 300-90020-25 Ethyl glycol7-10 Isoprodilic alcohol8-12 role acti1-2 Polyacrylamide 0.5-1 Urea2-4 Separate1 4-0.8 A mixture of synthetic fatty acids of the Syu-Ci6 fraction with tributyl phosphate, taken in the ratio 1: 11-3 Water Up to 100
