RESEARCH AND APPLICATION OF ASH AND SLAG WASTE IN RUBBER COMPOUNDS

Annotation. The article considers perspective directions of effective utilization of ash and slag wastes generated by coal combustion, and also provides information about their negative impact on the environment and humans. The efficiency of ash and slag wastes application as a filler in rubber mixture has been evaluated. The object of the study was ash and slag waste generated in the boiler house, used for the preparation of experimental rubber mixtures. The change of physical and mechanical characteristics of vulcanizates at replacement of technical carbon with ash-and-slag waste in the composition of rubber mixture in different ratios was evaluated. The result of determination of vulcanization characteristics, after introduction of ash and slag waste in the composition of rubber mixtures, is the increase of vulcanization start time and time of reaching the optimum of vulcanization, as well as a significant decrease in the value of the maximum torque, which indicates an increase in the elasticity of vulcanizate and can be useful in the manufacture of vibration- and sound-proof rubber products.

Keywords: ash and slag, rubber compound, filler, elastomer, carbon black, physical and mechanical properties.
