Title of the articleInvestigation of gradient materials based on PVC and of diglycidyl ether 1,4-butanediol
Abstract.Problem statement. Protection of building construction and structures with paint and lacquer materials, in particular styrene-acrylic, is one of the most common methods against corrosion. It is known that the level of performance of coatings is largely determined by the content of fillers in their structure, which may have different geometric shapes of particles. The aim of the study is to carry out a comparative analysis of the change in the level of properties of styrene-acrylic copolymers filled by silicate minerals with different geometric shapes and coatings based on them. Results. The main performance characteristics of styrene-acrylic paint coatings, filled by kaolin and wollastonite, possessing the same chemical nature – silicates, but with different geometric shapes of particles – were investigated. It is shown that the acicular structure of wollastonite allows a significant increase in the level of physical and operational properties of paint coatings. Partial replacement of wollastonite in an amount of 25 % by kaolin contributes to a significant improvement in the basic performance properties of paint coatings. Conclusions. The significance of the obtained results for the construction industry is that the use of fillers with different geometric shapes of particles can promote the manifestation of additive or synergistic effects, which in turn will allow to regulate the formulation in order to obtain coatings with a specified level of performance.
Keywords.kaolin, wollastonite, silicate fillers, styrene-acrylic copolymers, polymer coatings.
