Optimization of the Composition of Vibration-Absorbing Compositions Based on Butyl Rubber

The significance of the issue outlined in the article stems from the fact that, despite the extensive theoretical investigation of the properties of polymer-based composites, experimental investigations of the impact of frequency and temperature on the dynamic mechanical properties of butyl rubber-filled composites have not been sufficiently studied. This article is aimed at studying the influence of the concentration of additives-modifiers: industrial oil (MI), resin (AFFS) and bitumen (BN 90/10) on the dynamic mechanical properties of prepared chalk-filled mixtures based on butyl rubber and assessing the properties of the compositions using response surface methodology (experiment planning method). To optimize the composition, the influence of the factor on the response was investigated. The optimal composition of a vibration-absorbing composite material based on butyl rubber (BR) with high vibration-absorbing properties has been found, which makes it possible to select all the components included in the composite with a more optimal concentration. Based on the operational requirements for such materials, these values were: (BC — 77.52 g; chalk — 462.28 g; industrial oil — 61.79 g; alkylphenol-formaldehyde resin (APFR) — 37.8 g; bitumen — 36 g) Based on the research carried out, it is possible to use the obtained data for further prediction of properties, as well as for the development and production of a new composition of composite materials based on BC.
