(57) Abstract:Use: textile finishing production to impart hydrophobic properties to textile materials made of natural and chemical fibers. Essence: according to the first variant concentrated emulsion for water-repellent finish contains, wt%: paraffin 17,2 - 30,0; modified lignite wax 2 - 5; grease PVA-based petroleum butter, mineral oil and ceresin 1.8 to 5.0; isopropyl alcohol 8 - 15 and the water - the rest is up to 100. According to the second variant concentrated emulsion comprises, by weight. % paraffin 21 - 35; zirconium acetate 5,0 - 7,5; acetic acid 4 - 6; dispersed aluminum oxide of 0.5 - 1.0; if necessary, plastic lubricant STC 2,8 - 5,0 and water - the rest is up to 100. Properties of emulsions: stability during storage 18 - 24 months, vodovoroty cotton mantle tissue code 3122 on penetrometry 310 - 590 mm water. Art., water absorption after 1 h of 17.8 21.8 percent. 2 S. and 1 C. p. F.-ly, 2 tab. The invention relates to the field of chemistry, particularly to textile auxiliary substances (TBB) for final finishing of textile materials of different nature: cotton, wool, synthetic fabrics and their blends.do with water-repellent properties, tissue gain and other useful properties of fullness, crease resistance, etc. From a practical point of view, an important simple technology of impregnation of fabrics, and existing methods of finishing (ognovenko and double-bath) is preferable otnowennii.Given the considerable distance of most textile factories on the territory of the Russian Federation from manufacturers emulsion TBB and instability of supply are essential to the stability of the preparations in time and preserving their ability to be diluted with water with formation of stable impregnating baths. In the absence of the textile mills special ventilation is a significant factor also become fireproof properties used TBB.The invention relates to water-repellent means for ognovenko method of finish (as the most economical) of textile materials with open pores (as the most hygienic form).There are a large number of wax compositions for vodoottalkivayuschie finish prepared using emulsifiers as hydrophilic and hydrophobic nature, including various metal-containing soedinenie combined method of impregnation of fabrics with successive coats of polyacrylates, a mixture of paraffin-zirconium emulsion of fluorine-containing drug, aluminum sulfate, etc. But in this case, a double-bath method and the impregnation is obtained with closed pores (fabric for umbrellas). It is also known application to water-repellent finishing emulsions of paraffin, stable gel aluminum hydroxide. However, the sustainability of their time totally inadequate for long-term storage because of the instability of the gel aluminium hydroxide.Closest to the technical essence and the achieved result to the invention is a concentrated emulsion of the type oil-in-water"  containing 16-20% paraffin (including 4% mineral wax), 1,6-5,0% acetate, zirconium, 2% acetic acid, 10% methyl ethyl ketone and water.However, this emulsion is also not without drawbacks:
achieved degree of dispersion, coagulation and kinetic stability of the original emulsions does not provide the ability to store, transport and use more than 10-12 months, and the diluted emulsion with a concentration of 80-200 g/l (impregnating baths) above 6 h, which complicates their use;
the nature and proportion of the components in the impregnation of fabrics once is in, get after finishing;
emulsions are legkovosstanovimymi liquids (flash temperature TVSP. 40-42aboutC), which significantly complicates the process of production, storage, transportation and use them.The purpose of the invention increase the sustainability of the source of a concentrated emulsion significantly more than 12 months (two years), and impregnating baths above 6 hours (up to 12 hours), the increase and stabilization of water-repellent effect. When this tissue acquire additional useful properties such as crease resistance and fullness, reducing fire hazard properties of emulsions lowering the temperature of the flash.This objective is achieved in that in the composition of the emulsion containing, as main components paraffin, zirconium acetate, acetic acid, a polar organic solvent and water, additionally injected plastic grease STC (GOST 19537-74), modified lignite wax (TU 615-04-49-93) acid value (K. H.) 15-20 mg KOH/g and a melting point (So square ) 78-80aboutWith, as the polar organic solvent is isopropyl alcohol (composition A).In addition, introducing solid dispersed aluminum oxide (TU 609-3916-75) (Sazavou turn out one way, and emulsion compositions a, B, C have approximately the same performance.Unlike the prototype  composition And consists in the additional introduction of plastic greases STC (1.8 to 5.0 wt.), modified lignite wax with K. H. 15 to 20 mg KOH/g H O. 140 to 180 mg KOH/g, Tpl.=78-81about(2.0 to 5.0 wt.) and isopropyl alcohol (8.0 to 15.0 wt.), as well as in the increased content of wax (up to 30.0 wt. ) and acetic acid (up to 6.0 wt.), this allows the emulsion at the interface of the adsorption layers of new, non-emulsion prototype structure of di-(three)-acetates of Zirconia and isopropanol, contributing to the increased stability as a source of concentrated emulsions and impregnating bath of dilute emulsions. In addition, the introduction of the emulsion isopropanol reduces its temperature flash 10-12aboutCompared to the emulsion prototype containing methyl ethyl ketone, i.e., to reduce its Flammability.Unlike the prototype  composition B is in the additional introduction of the emulsion solids dispersed aluminum oxide (0.5 to 1.0 wt.) and also in the increased concentration of paraffin (to 35.0 wt.) and acetic acid (up to 6.0 wt. ). As a result, grania stability of the emulsion and the water-repelling performance. In addition, this composition is generally trudnovospolnimymi (flash is not detected up to 280-300aboutC), that is metopograpsus.Unlike the prototype  composition is the other introduction of the emulsion solids dispersed aluminum oxide (0.5 to 1.0 wt.) and plastic lubricant STC (2.8 to 5.0 wt.), as well as in the increased concentration of paraffin (to 35.0 wt.) and acetic acid (up to 6.0 wt.), what also contributes to the formation of "book" patterns on the phase boundary of the emulsion and provides increased stability of the emulsion, the increase and stabilization of water-repellent effect and low fire hazard processes of manufacturing the source of a concentrated emulsion, storage, transportation and application.The components of the compositions and their ratios are presented in table.1 in comparison with the prototype, and the properties of the obtained emulsions in table.2.The proposed emulsion (all variants) are obtained by the method  using a piston homogenizer slotted type Manton Gaulin under pressure inlet 150 up to 450 kg/cm2, which served a coarse pre-emulsion of the starting components at a temperature of 80aboutC. appearance of finished emulsion: mobile liquid b is pricheskoj microscopy, the bulk of the particles is from 0.5 to 1.85 μm. The sustainability of the source of concentrated emulsions significantly above the 12 months to 24 months), and impregnating baths with drug concentration of 80-200 g/l higher than 6 hours (up to 12 hours). Within these periods of storage of the concentrated emulsion is diluted with water in all proportions. When ognovenko the way to finish at 2-, 3 - roll placowka emulsions give a high and stable (10-20% above recommended norms and 15-30% higher than the prototype) water repellency of fabrics of different nature and their mixtures. Impregnation is obtained with open pores. At the same time is achieved by the additional effect of fullness and nesminaemosti (15-20% higher than that of the emulsion on the prototype), equal in magnitude, respectively 60-65% and 500-1000 mg/cm2. Flash emulsion (composition A) 10-12aboutBelow emulsion of the prototype, and compositions B and even lower is not determined until the 280-300aboutC.Basic physical and chemical properties of the emulsion according to the invention, in comparison with the prototype presented in table 2.
