FIELD OF APPLICATION

The invention relates to a dehumidifier for hides and skins intended for the leather industry in the process of processing hides and skins.

BACKGROUND OF THE INVENTION

Alkyl phosphates, anionic and non-ionic surfactants for the reduction of skins are known (US 1214765A). Oily skins have a pronounced tendency to hydrophilia.

SUMMARY OF THE INVENTION

The invention relates to a dehumidifier for hides and skins. The oily skins are greased with it, and it is in the form of an aqueous emulsion containing by weight% alkyl polyglycol ether phosphate and / or phospholipid from 1 to 60 in combination with components such as neutral oils of natural or synthetic origin and mineral oils from 10 to 70 polyglycol ethers. from 4 to 55 and higher fatty alcohol esters and higher fatty acids from 3 to 50, chloroparaffins, alkylaryl sulfonates from 5 to 50, and alkanesulfonates in the form of their alkali salts from I to 45, alkylaryl polyglycol ethers.

The corresponding alkyl polyglycol ether phosphates should be in the form of salts. They are prepared by known methods, for example by converting the polyglycoleter of the higher fatty alcohol with phosphorous oxychloride, phosphorous pentoxide or polyphosphoric acid upon heating. Following the conversion, the resulting phosphoric acid mono- and diesters are treated with the corresponding sodium and potassium hydroxides or alkanolamines.

The resulting alkyl polyglycol ether phosphates and / or phospholipids are combined, depending on the purpose of the skin, with anionic surfactants, non-ionic surfactants, as well as natural or synthetic oil or chloroparaffins.

Preferably, the anionic surfactants are in the form of alkali metal salts.

The weight fraction of alkyl polyglycol ether phosphates and / or phospholipids in the preparation of skin ointments is from 1 to 60% by weight. Working emulsions are obtained by dilution with water to obtain the desired concentration in accordance with the technology used to reduce the skin of hollows.

The degreasers according to the invention can be treated with different types of skins previously cured by different technologies (eg chrome, zirconium, aluminum).

In certain cases, after curing, the cations of polyvalent metals are further treated. The processing is carried out by the method of extraction from aqueous medium.

The lubrication according to the invention produces skins with excellent softness, feel and fullness characteristics.

EXAMPLES FOR THE IMPLEMENTATION OF THE INVENTION

EXAMPLE 1 A diluent was prepared containing, in% by weight: alkyl polyglycol ether phosphate-30, alkyl polyglycol ether C ₁₀ -C ₁₈ with 2 to 15 mol ethylene oxide - 10, polyglycol ester of high fatty acid C ₁₆ -C ₂₂ with 2 to 10 mol ethylene oxide - 15, mineral oil with a viscosity at 40 ° C 14,0-15,5 cc -25, phospholipid on a plant base - 20. The components are added sequentially to the preheated to 50-60 ° C mineral oil and polyglycol ester of higher. fatty acid with continuous stirring and circulation until complete homogenization.

The thus obtained oil emulsion in the form of an aqueous emulsion is treated with chrome-hued skins as follows.

In a drum with a speed of 16 rpm and a TC of 1.0-1.2 at a temperature of 55-60 ° C, 10% by weight were added. ointment to fold skin weight - rotation 60 min.

% Basintan N - rotation 20 min;

% Relugan R E - rotation 40 min;

0.5% HCOOH - rotation 20 min;

0.5% Catalix GS rotation 20 min.

The following operations of the leather processing technology - washing, cooling, standing, drying and sliding are carried out according to the current technology of the leather enterprises.

The lubrication controls the exhaustion of the oils from the solution, their penetration in depth and their distribution in the topographic areas of the skin.

The lubricants according to the invention absorb very well from the skin and are evenly distributed throughout the skin cross section.

EXAMPLE 2 Work as in Example 1, with the ointment contained in% by weight. : plant-40 phospholipid, higher fatty acid polyglycol ester C ₁₂ -C ₂₂ with 2 to 15 mol ethylene oxide - 5, alkylpolyglycolether C _g -C ₁₂ with 6 to 15 mol ethylene oxide 5, alkylpolyglycoleter with C ₁₀ -C _Ig with 2 to 15 mol ethylene oxide - 10, mineral oil with a viscosity at 40 ° C 14.0-15.5 cc - 40.

Example 3. Work as in example 1, the degreaser containing the following components in% by weight: plant-based phospholipid - 40, fish oil - 15, alkylpolyglycolether C C ₂₂ with 2 to 15 mol ethylene oxide - 17, mineral oil with viscosity at 40 ° C, 14.0-15.5 cc - 14, chloroparaffin - 10, nonylphenolpolyglycolether with 4 to 20 mol of ethylene oxide - 4.
