Analysis of time dependence of mechanical stresses uniaxial tensile sample of highly plasticized PVC flame retardants

Выполнен анализ результатов сравнения механических свойств наполненного ПВХ- пластиката, для которых обеспечение требований пожарной безопасности диктует рецептуры ПВХ-пластикатов, предназначенных для изоляции, оболочек и внутреннего заполнения кабелей. В частности, высокое значение кислородного индекса, низкое значение параметра дымообразования и выделения хлористого водорода.To ensure fire safety requirements of electrical cables designed plasticized PVC formulations intended for insulation, membranes and internal filling cables. Such formulations must be developed with a higher oxygen index and lower toxicity of combustion products. The analysis of the results of the comparison of mechanical properties of filled flexible PVC, for which provision of fire safety requirements dictate plasticized PVC formulations intended for insulation, membranes and internal filling cables is presented. In particular, the high oxygen index, low smoke generation and parameter value selection chloride conduit. Experimental evaluation of the internal friction coefficient provides additional information on the processes of deformation and fracture of highly filled plastic compound in uniaxial tension. To select the technological parameters of processing PVC compounds filled with flame retardants, and search the optimal composition of multicomponent structures in cable production is necessary to monitor the mechanical characteristics of the respective samples of composite materials
