Abstract
The aim of the present work is to investigate the possibilities of using waste sunflower oil as a modifying additive in order to eliminate some disadvantages of polyurethane adhesives used in the production and performance of insulating composites from ground waste rubber vulcanizates. A composition and a technological model for the production of sound- and shock-absorbing composite material have been developed as a result of the present study. A positive effect of the modifying additive on the technological process and the properties of the composite materials has been established. It is attributed to the composition of the waste sunflower oil comprising different types of fatty acids. The conducted tests and the obtained results give grounds to believe that the composite material developed can find applications as a sealing element in railways of rail and tram transport, in construction for sound insulation of buildings, as well as for covering children‘s and sports grounds.
