Study of the Resistance of Shoe Sole Compositions to various Aggressive Environments
Abstract
In this paper, the stability of shoe sole compositions to various aggressive media was studied: in water, in gasoline, in diesel fuel, in antifreeze, in industrial oil, in acetone and ethyl acetate. The kinetics of swelling of polymer compositions in various aggressive media for 3 days was determined. It has been determined that the type of filler in the composition has a significant impact on the oil and petrol resistance of the material, therefore, a correctly selected filler will make it possible to significantly improve the ability of sole materials to resist aggressive media. Samples of sole materials were subjected to natural, thermal and light aging. It has been proved that the obtained compositions for casting parts of the bottom of the shoe well withstand tests for natural and artificial aging and can be recommended for use in working conditions with increased thermal and light exposure.
