Properties and Structure of Butadiene-Nitrile Rubber Modified by Thermoexpanded Graphit
Abstract
In this paper, the results of study of operational properties and structure of a sealing rubber based on butadiene-nitrile caoutchouc and modified by thermally expanded graphite are presented. Modification of the rubber based on butadiene-nitrile caoutchouc by thermally expanded graphite produces an elastomeric material with high elasticity, frost-resistantсe and improved tribological characteristics. Tribological tests of the modified rubbers have shown the decrease of volume wear and friction coefficient. It is established that intercalation of caoutchouc in interlayer space of thermally expanded graphite and increase of degree of cristallinity on a surface of the modified samples is the reason of improvement of technical properties of elastomeric material. Therefore, the obtained results allow to recommend the presented elastomeric materials for production of mobile sealing elements, and to state that the sealing products made of it will be efficient and durable.
