PROBLEM OF USING WASTE OF PAINT AND VARNISHING MATERIALS AND THEIR DISPOSAL

Abstract

The relevance of the research. Corrosion of metals is the most important problem with which large losses of metals are associated. Hundreds of tons of metals are irretrievably lost annually from corrosion, therefore, all studies aimed at the corrosion protection of metals are appropriate and relevant. The main aim. There are various methods of anticorrosion protection of metal parts, but there is no sufficiently effective method for specific conditions of anticorrosion protection. The aim of this work is the use of waste paint and varnish materials to obtain anti-corrosion coatings of metal parts. Objects: waste paint and varnish materials obtained by painting cars. Methods: study of the physicochemical properties of the waste; selection of compositions for dissolving paintwork materials; formulation development and receipt of anticorrosive mastic; testing the obtained anticorrosive paint coating for adhesion, chemical resistance, film strength in bending, impact strength, fire resistance, frost resistance; preparation of metal plates for applying a protective paint coating and solutions of various compounds for testing to determine the mass loss of experimental metal samples; determination of the most effective component and quantitative composition of the resulting coating. Results. The authors have developed and obtained the mastic based on gossypol resin and solid waste of paints and varnishes. Gossypol resin is a waste oil-fat plant. The resulting mastic was tested in laboratory conditions in terms of quality, positive results were obtained. Operational tests were carried out in road conditions, the car's mileage was 12,780 km, no changes were found on the surface of the coating.
