SU971881A1 - Composition for fat-liquoring skin - Google Patents

Description

one

The invention relates to light industry and can be used in leather processing for fattening leather.

The closest in technical essence to the invention; is a skin grease composition that includes chlorinated paraffins, mineral oil, alkyl sulfates of fraction C, -Cn and fat sulfo emulsifier and non-ionic surfactant t j The disadvantage of this composition is that it does not provide a sufficiently high degree of softness when The development of such types of leather as clothing and glove is, in addition, this fat composition is stratified during storage for more than 6 months, which makes it difficult to store and use in tannery conditions. 20

The purpose of the invention is to increase the stability of the fat composition and improve the quality of the skin.

This goal is achieved by the fact that the composition for fattening of the skin, including chlorinated paraffins, mineral oil, -C alkyl sulfonates of the C-fraction, fat sulfo emulsifier and non-pathogenic surfactant, additionally contains perchlorethylene oxygen-containing compounds, with the following ratio of components, wt.%:

Chlorinated

paraffins 7-15

Mineral oil Alkylsulfonates

10-15 fractions of C The product of sulphating a mixture of porcine fat with polyfunctional oxygen-containing

10-15 compounds

Non-ionic surfactant 10-15

Perchlorethylene. 0.2-2

In this composition, Polyx-27 uses Perchlorethylene corresponding to TU-6-0,1-956-7.

The product of sulphating a mixture of pig fat (polyfunctional oxygen-containing compounds (.PPKS) is manufactured according to TU 6-10-1010 | -b5-80 under the trade name SEZH-S Borislav Chemical Plant. The components are taken in the ratio of FF: PFX 1: 1.-2 As a PFCS, upon receipt of an SEA-C, use is made of a product obtained from the deep catalytic oxidation of fatty acids and by-products of their production — unwashed. The length of the PFX carbon chain is .5- The product is manufactured according to TU 38 of the USSR 201297-78 Berdsky Order of the Red Banner of Labor experienced ftemaslozavodom.

Example 1. A fat composition is obtained by mixing the components at 80-95 ° C until homogenization, but not less than 2 hours. The order of administration of the components is not regulated.

The formulation of individual samples of the compositions are given in table.1.

Example 2. The fatting of the chrome semi-finished product from the raw material of the semi-skimmer with the obtained compositions was carried out according to the parameters of the standard procedure.

Indicators of the properties of the skin. Are given in table 2.

Example 3. The stability of the fat composition is defined as the time of the appearance of the interface in two layers during storage of the sample in a cylinder, with a capacity of 100 ml of clear glass. The time of occurrence of delamination is for a known compound of 6 months.21 days, for the proposed 12-15 months.

The proposed fat composition insulates compared with the known increase in the stability of the fat composition during storage for more than 12 months. (from 6 months), decline

the durability of the resulting leather to 10 mn / m15 mn./m. In addition, the advantage of this composition is that, given the sustainability, it can be prepared under the conditions of chemical plants and sent to consumers in tanneries in containers of any capacity. The organization of its production is possible on the equipment and production areas of Polix. The ability to use

as a non-ionic surfactant like

ethoxylated alcohols and mixtures of ethoxylated and oxypropylated alcohols and alkylphenols, expands the raw material base, which is important

in conditions of deficiency of non-ionic surfactants. So, you can use, by the presence of: synthanol DSP, syntanol DS-10, prevotsel, OP-7, OP-10. The proposed product, in terms of the main indicators of the properties of the fat composition and the leather obtained, is at the level of the best imported samples.
