PROPERTIES OF THE LAQUER COATINGS BASED ON MODIFIED TERPENOMALEINIC RESINS
Abstract
The development of electrical products with increased technical and economic indicators requires further improvement of electrical insulating materials. Due to the wide introduction of automatic winding methods, it is of great importance to develop varnish coatings that ensure the reliability of insulation under significant mechanical stresses. This study was devoted to the development of the operational properties of electrical insulating varnishes by developing technologies for high-efficiency secondary products of terpenomaleinic resins (TMS resins) and thermosetting compositions based on them. In this work, physical and chemical properties of TMS resins modified with heavy metal salts such as acid number (AN, mg of KOH/g), softening temperature (Ts, °C), viscosity (v20) and destruction temperature (Td, °C) were studied. The effect of the obtained TMS resins on physical and mechanical properties of lacquer coatings based on them such as film thickness (μm), hardness of the varnish coating (conventional units) and the corrosion resistance was studied. The effect of TMS resins modified with salts of heavy metals (Co, Mn and Zn acetates) on physical and mechanical properties of lacquer coatings based on them was studied as well.
