This article presents the results of research work devoted to improving the characteristics of paint and varnish coatings based on aqueous dispersions of polyacrylates; it is proposed to modify them by introducing mineral raw materials as fillers and hydrated lime, with subsequent processing in a vortex layer apparatus. The introduction of activated diatomite does not cause the deterioration of covering power, adhesion or an increase in the porosity of the paint material. The modification of coatings contributes to an increase in their operational properties, which can be associated with a reduction in the free volume in the composite and the formation of polymer boundary layers with modified physical and chemical properties. The aim of this study is to obtain a water-dispersion paint and varnish composition containing modified diatomite on a polyacrylate basis and, subsequently, study its main physical and mechanical parameters. The work has been carried out by the following method: determination of porosity, adhesion, elasticity and covering power of the control composition; determination of porosity, adhesion, elasticity and covering power of the obtained composites using modified filler; investigation of the influence of radiation on the infrared spectrum of the paint coating surface using a FLIRB620 thermal imager. As a result of this research work, it was noticed that the modification of water dispersions with silica-activated diatomite helps to eliminate the main disadvantages of materials and coatings based on acrylate binders—low water resistance and low physical and mechanical characteristics. The introduction of modified diatomite into water-emulsion paint on an acrylate base does not lead to the deterioration of the main performance characteristics of paint coatings—porosity, adhesion, elasticity and covering.DOI

Практическое значение
he practical significance of this study lies in the development of an improved water-dispersion paint and varnish composition based on polyacrylate dispersions modified with silica-activated diatomite. The proposed approach enhances the water resistance and physical-mechanical properties of acrylic coatings without compromising key performance characteristics such as adhesion, elasticity, covering power, and porosity. The use of modified natural mineral fillers and vortex-layer activation technology provides a cost-effective and environmentally friendly method for producing durable protective and decorative coatings. The obtained materials can be applied in construction, civil engineering, and industrial finishing processes, where increased service life, resistance to environmental factors, and improved coating performance are required.Квартиль
