Abstract: The ability to manage product quality, improve performance, adhesion, and wear resistance are priorities in the paint and varnish industry. One of the ways to influence the quality of paint and varnish materials (LCM) is the introduction of highly dispersed additives (HDA) into the polymer base. In the work, the selection of HDA and the method of its introduction into the paint was carried out in order to improve its wear resistance, which is important when used, for example, for road markings. The influence of three types of HDA was studied: electroexplosive aluminum oxide, ultrafine diamonds of detonation synthesis, and aluminum oxidealumina (technogenic waste of the Achinsk alumina combine). Electroexplosive aluminum oxide is of the greatest interest as a highly dispersed additive for improving the wear resistance of the obtained composites. It was found that the introduction of 0.05 wt. % explosive Al2O3 allows you to increase the wear resistance in the laboratory by 30% while maintaining other properties.
Index terms: highly dispersed additive, paint and varnish materials for road markings, wear resistance.
