25 Colloidal-chemical properties of emulsifiers by the IVP trademark for reverse emulsions — Candidate of chem. Sci. Aristov B. G., Candidate of chem. Sci. Konichev M. A., Candidate of chem. Sci. Smrchek V. A., Candidate of chem. Sci. Yarovaya O. V.
Abstract. The study of colloidal-chemical properties of emulsifiers by the IVP trademark for reverse emulsions, which are by chemical nature a solution in an organic solvent of derivatives of triglycerides of fatty acids of tallow or sunflower oil and ethanolamines. The acid and hydroxyl numbers, as well as the hydrophilic-lipophilic balance of the synthesized emulsifiers were determined. Their surface activity, micelle formation and emulsifying ability were used. It is shown that the studied diphilic compounds belong to the class of colloidal surfactants with high surface activity and the ability to micelle formation. For all samples, the experimentally determined surface tension isotherms and critical concentration of micelle formation (ССМ) values practically coincided, although the samples have different chemical structures. This indicates both their adsorption on the glass surface of the capillary for measurements, and the peculiarities of the association of surfactant molecules in a non-aqueous medium. It is obvious that the determination of isotherms of surface tension, CСМ, surface activity and Gibbs adsorption in a non-aqueous medium by conventional methods is incorrect. The stabilizing ability of reverse emulsions of water — alkyd varnish with the addition of the studied emulsifiers has been studied. It is shown that emulsifiers with a high hydroxyl number have the best emulsifying effect, which can be recommended for the production of water-containing alkyd enamels.
Keywords: emulsifier, surface activity, surface tension, micelle formation, hydrophilic-lipophilic balance, hydroxyl number, adsorption, emulsifying ability.

10 Stability and coagulation of mixed water dispersions of mineral powders and latexes — Prof. Koshevar V. D., PhD Kazhuro I.P.
Abstract:
Systematic study of aggregate stability and coagulation of water binary mixtures of synthetic latexes and mineral powders of different chemical nature and particles sizes depending on the charge and electro kinetic potential of particles, concentration of disperse phases and pH of dispersion medium was performed using photo-sedimentation, differential-thermal, turbidimetry, ζ-photometry, IR-spectroscopy and scanning electron microscopy methods. High aggregate stability of mixed dispersions of acrylic, styrene-butadiene latexes with kaolin and titan dioxide in basic media was established, it is reasoned by the localization of latex particles of colloidal size near negatively charged mineral particles. In acid media (pH=3.5) substantial drop of aggregate stability of these binary systems accompanied by the formation of flaky non-dispersible precipitate as a result of homo- and hetero-coagulation processes taking place. The stability of binary mixtures of all investigated latexes and microcalcite is much less dependent of chemical nature of latexes and changes of pH of the medium. Possible reasons of such behavior of the compositions being
studied are discussed.
Keywords: kaolin, titanium dioxide, microcalcite, latexes, mixed dispersions, aggregate stability, electro kinetic
potential, heterocoagulation.

20 Method for increasing the hardness of 1K aliphatic PU coating — Antipova E. A., Korotkova N. P., Styunina A. O.
Abstract:
In this paper, the influence of the concentration of rigid segments in a PU elastomer on its technological and physical-mechanical properties, as well as on chemical resistance, is investigated. The study was carried out using PU-elastomeric binders synthesized on the basis of aliphatic polyester with MM 2000 and functionality 2, aliphatic polyisocyanate and chain extension. On the basis of these components, a number of pre-polymers with a mass fraction of NCO groups of 8.5% and different concentrations of rigid segments were synthesized. The synthesis of the pre-polymers was carried out according to a well-known technology at a temperature of 70–80 °C.
The physical and mechanical properties of the cured material were studied on films that were prepared by pouring a pre-polymer solution in a system of solvents methyl ethyl ketone : xylene = 60 : 40 into glass molds treated with an anti-adhesive. The films were formed under the following conditions: 1 day at the temperature and humidity of the room; 12 hours — in a thermal cabinet at 80 °C. The complete curing of the films was controlled by the gel-fraction method (extraction with acetone in the Soxlet apparatus). The gel fraction in the samples was no more than 4%, which indicates a degree of curing of >95%. The obtained films were tested on the machine «Instron 3369» according to GOST 270-75.
The protective properties of PU film samples were evaluated at room temperature by the value of the equilibrium degree of swelling in the following media: distilled water, transformer oil.
The adhesion of the cured coatings to glass and stainless steel was determined by the cross cut method in accordance with GOST 15140-78.
Optimization of the concentration of rigid segments allowed the development of a new 1K aliphatic PU binder for obtaining UV-resistant coatings with high hardness, strength, adhesion and chemical resistance.
Keywords: polyurethanes, anti-corrosion coatings, UV-resistant coatings.

16 Coatings with reduced adhesion to ice — Doctor of Technical Sciences Drinberg A. S., Tarasova I. N., Nedvedsky G. R., Candidate of Chemical Sciences Mametnabiev T. E., Litosov G. E., Alikin M. B., Okhrimenko A. G.
Abstract:
Of the many ways to prevent icing: thermal, mechanical, physical and chemical the most interesting is the use of anti-icing coatings, which are subject to a number of specific requirements, the main of them-reduced adhesion to ice. There are many approaches to creating coatings with reduced adhesion to ice. This includes the introduction of polysiloxanes, the use of fluorinated polymers or organosilicon. Also, one of the promising directions of creating such coatings is the use of superhydrophobic coatings. However, for comparative tests of various coatings, it was necessary to develop a special method for determining the adhesive strength to ice and it is desirable to display it in physical quantities by direct tests, rather than indirect (as the method of cross cut by GOST 31149-2014). The SPbGTI (TU) developed a method and designed a special installation for determining the adhesive strength to ice of various coatings. To conduct tests to determine the adhesive strength to ice, a special nozzle was developed and manufactured-a cup and steel rods on which the test paint is applied and subjected to freezing in the freezer up to –18 oC. This method allows to determine the physical value of the adhesive strength to the ice in MPa.
The following coatings were selected as test samples: organosilicon-based coating, organosilicon-based coating with the introduction of Foraflex fluoroplastic additive, organosilicon-based coating with the introduction of glass microspheres, epoxy-based coating, silosane-based coating, fluoroplastics-based coating, pure metal (steel 3).
The results were processed on a computer using a special program for numerical data analysis and scientific graphics — Origin. It is established that the most effective anti-icing coatings are coatings based on organosilicon and fluoropolymers, which have an adhesion to ice of 4–6 MPa.
Keywords: organosilicon resins, adhesion, anti-icing coatings.

15 DESMODUR ® aliphatic polyisocyanates for elastic coatings: new features —Golling Florian, Eroma Boris, Verboom Dik, Tasich Srba
Abstract:
New specialized aliphatic polyisocyanates that allow varying the physical, mechanical and paint properties of coatings, as well as meeting the stricter requirements of industrial safety (regulation of the emission of volatile organic compounds( VOC), limiting the content of residual monomers) are considered. The series includes products with increased functionality (for faster curing and better chemical resistance) and low viscosity (for compositions with low or zero VOC content), as well as products that allow you to increase the flexibility and elasticity of the final coatings, positively affecting properties such as scratch resistance, abrasive wear and impact. This series includes allophonates of hexamethylene diisocyanate, prepolymers based on hexamethylene diisocyanate and isoforone diisocyanate with polyesters or polycarbonate diols as skeletal molecules. Tests of hardness (Shore A, D), elasticity, tensile stress, and elongation showed the superiority of new products over traditional ones.
Keywords: aliphatic polyisocyanate, coatings, hexamethylen-diisocyanate, isophoron-diisocyanate.

Abstract:
Coatings with certain electrical characteristics are considered: liquid coatings intended for application in an electrostatic field, powder coatings for application in a high-voltage electric field, and coatings for application by electrodeposition methods. It is believed that the optimum electrical and physical-mechanical properties of electrically conductive coatings are achieved when two interpenetrating phases occur in the coating: a continuous grid of an electrically conductive filler and a grid of a film-forming agent oriented in it. Electrically conductive pigments and fillers allow electricity to pass through the coating or dissipate. Powders of silver, gold, copper, aluminum, tin, iron, and nickel are used in conductive coatings.
Keywords: metal pigments, specific volume electrical resistance, polymer compositions.
