CURRENT STATE OF PROTECTIVE AND DECORATIVE PROPERTIES OF WATER-DISPERSION ACRYLIC COMPOSITIONS

Abstract

The rapid progress of water-dispersion paints from the water-diluted group is due to a number of their advantages over other paint and varnishes from the category of environmentally friendly. The formulations of paintwork materials are dominated by aqueous dispersions of acrylic copolymers, acrylic styrole copolymers, homo- and copolymers of vinyl acetate. One of the main methods of targeted regulation of the properties of polymer composite materials and coatings is the use of surfactants (surfactants). As a result of adsorption phenomena, their physical interaction with the surface of dispersed particles and substrate, associations with film-forming molecules can significantly change the deformation-strength, insulating, adhesive, coloristic and other properties of paint coatings. The purpose of the work is a reasonable choice of polymer surfactants for obtaining water-dispersion acrylic coatings with a given set of properties. This determines the relevance of research. Objects. Film former - acrylic polymer, inorganic pigment - rutile-shaped titanium dioxide, modifying additives - polyestersiloxane copolymer (PES) and sodium polyacrylate (PAN), aqueous solvent. Conclusion. Analysis of the state and current trends in paint and varnish materials indicates the prospects of using water-dispersion acrylic compositions. The study of the physical and chemical regularities of processes involving surfactants, developed both in the volume of film-forming and at the interphase boundaries of its interface with pigment and air, is an important prerequisite for the formation of scientifically based approaches, when obtaining effective protective and decorative properties of coatings of water-dispersion compositions.
