Abstract

The essence of the invention: the composition contains the following components, May%: the triethanolamine salts of the acidic alkyl phosphates of the fatty acid monoglycolic esters of the dcrC27 fraction, consisting of (in May%) branched 20-60, linear 40-80, including carbonyl-containing 8-20, di-carboxylic 1-18 and unsaturated acids 15-45 with admixture of neutral and fatty substances 60-80, sulfonic derivatives of fish oil 15-20, and mineral oil - the rest. 2 tab.

Description

The invention relates to light industry and can be used in the leather industry for fattening a wide range of leather from various types of raw materials.

A known composition for fattening of skins containing sulphated fish oil, mineral oil, and esters of mono- and polyhydric alcohols and isomeric and linear saturated, unsaturated carbonyl-containing, keto, oxy-, and dicarboxylic acids (esterine MG). When fattening with this composition, high levels of tensile strength are achieved, however, the elasticity of the skin is low, the preparation is expensive. Formulations based on the preparation Ephosol are also known in the following combinations:

a) ephosol. sulfated fish oil, VNIIZh, alizarin oil;

b) ephosol, VNIIZh, sulfated fish oil;

c) ephosol, VNIIZh.

However, these compounds, when used, either give the skin high elasticity with a low value of strength (a), (b) or a high value of strength with insufficient elasticity. Preparations Efosol and VNIIZh are expensive, besides Efosol is obtained from a scarce raw material - secondary alcohols.

Closest to the invention is the preparation Efosol, consisting of triethanolamine salts of alkylphosphates of the fraction and aliphatic alcohols of the fractions. However, when using the drug reaches a low value of elasticity with a good value of strength. Drug road

Comparison of the quality indicators of treated leather and the cost of processing compositions according to analogues, prototype, and the proposed composition are given in Table 1

The aim of the invention is to improve the quality of the finished skin by improving the elasticity while maintaining high
