Influence of silicon dioxide nanoparticles on the properties of paint-and-lacquer coating made of perchlorvinyl enamel

Effect of nanosized silicon dioxide on mechanical properties, texture, and structure of a polymer paint-and-lacquer coating made of gray KhV-16 enamel based on perchlorovinyl and glyphthalic resins is studied. It is established that the abrasion strength, hardness, and elastic modulus are larger than in the case of the original coating. Various methods are used to analyze the structure of the resulting samples of paint-and-lacquer coatings. It is established that the structure changes and the mechanical properties of the coatings improve because of the formation of new structure-forming centers in the composite coating due to the addition of nanosized silicon dioxide.
