A method for producing an anticorrosive paint based on nanostructured polyvinyl varnish

Introduction. Most of the paint and varnish materials are produced from imported raw materials using foreign technologies. Due to the growth of the construction industry, demand for varnishes and paints has significantly increased. Varnishes and paints provide a protective coating for buildings and structures. Therefore, the need for paint and varnish products made from locally sourced materials is relevant not only in terms of import substitution, but also in terms of economics. The materials used as lacquers are composite compositions. They are made by applying them to a selected surface, resulting in a solid polymer film with appropriate properties. This type of materials is used to coat and protect structural building materials from external influences, and gives them the necessary color and texture. The production of nanostructured anticorrosive paints based on PVC has such advantages as environmental friendliness, high adhesion, high dispersion, low opacity, low viscosity, and environmental resistance. Methods and materials. The scientific research is aimed at obtaining nanostructured lacquer paint by modifying PVC with organic solvents and montmorillonite, a clay mineral of various extraction depths from the Talalaevsky deposit located 20 km from Sterlitamak, Republic of Bashkortostan. The purpose of the scientific work is to use clay minerals consisting of oxides and silicates of aluminum and magnesium with a small content of sodium and calcium salts, which act as nanostructuring binders. The performance characteristics of the obtained nanostructured paint samples were tested for adhesion, opacity, drying rate, and elasticity. Results. The research results have shown that the use of clay as a nanostructuring modifier of PVC paint makes it possible to obtain a product with characteristics corresponding to regulatory documents. Conclusion. This study aims to develop a nano-lacquer paint made from locally available raw materials that can be used to coat building facades and other construction surfaces.
