Acoustic and Dynamic Characteristics of Elastomeric Building Materials Based on NBR Rubber

Acoustic and dynamic characteristics of perspective elastomeric building materials based on NBR rubber of K-FONIK type are considered. As a result of the conducted complex of studies of elastomeric materials, which are based on different types of rubbers, new data on their sound-insulating, sound-absorbing and dynamic characteristics are obtained. The data obtained make it possible to determine the possible limits of practical application of the studied materials. It is established that elastomers obtained on the basis of NBR rubber can be effectively used as sound-insulating coatings of air ducts and pipelines for various purposes, in aerodynamic noise silencers, as well as in vibration-insulating structures and vibration damping elements. The obtained results make it possible to evaluate at the design stage the acoustic efficiency of the accepted structural solutions aimed at improving the sound insulation of the walls of air ducts and pipelines, as well as in other structural elements, which are used elastomeric building materials of K-FONIK type. The results of studies of currently developed elastomeric materials show a wide range of their possible applications as sound insulation structures. It will allow designers to make purposeful development of new constructive solutions, proceeding not only from requirements of providing sound insulation, but also from economic requirements. The data obtained can be useful for developers of these types of materials in order to expand their application in construction practice.
