Performance Characteristics of Styrene-Acrylic Polymer Compositions and Coatings Filled with Dispersive Components

Abstract

AbstractThe object of the study is kaolin activated in the vortex layer apparatus, which is used as a filler for styrene-acrylic paint coatings. A comparative analysis of the performance characteristics of coatings filled with initial and activated kaolins was performed. Dispersion analysis was chosen as the research method, which allowed the authors to establish that the processing of the filler in the vortex layer apparatus caused an increase in its dispersion to 6 microns. In filled paint coatings, changes in the indicators of washability, water/moisture absorption, adhesive strength, as well as resistance to aggressive media, including model ones simulating the process of biological corrosion, were determined. Coatings and the condition of their surfaces after exposure to liquid media were fixed by the CIELab method by changing the color characteristics. It was found that filling with activated kaolin provides an increase in the level of performance characteristics of coatings – washability by 3.5 times, water absorption by 2.5 times and adhesive strength by 1.5 times, as well as resistance to aggressive media.KeywordsStyrene-acrylic copolymerCoatingsVortex layer apparatusActivation
