Hybrid Bipolymeric Structures Based on Butadiene-co-Acrylonitrile and Styrene-Butadiene Rubber Reinforced with Nanoparticles

This work reports new polymeric structures based on butadiene-co-acrylonitrile and butadiene-styrene rubbers, reinforced with nanoparticles of functionalised clay by the addition of ingredients such as protective agents, accelerators, plasticizers, etc., in order to obtain polymeric structures with predetermined characteristics. These were developed on a roller mill and their composition is designed so as to be processed into finished products by press molding, using the optimum processing technological parameters. Determining the optimal batch and ingredients in the structure of hybrid bipolymeric compounds based on general purpose polymers used in the footwear industry and optimum technological processing conditions led to obtaining qualitative performance in terms of physical-mechanical properties higher than those imposed by standards in force, especially concerning hardness, resistance to petroleum oils and resistance to high temperature for a long time. Polymer structures were characterized in terms of behavior in aggressive environments, high temperature resistance, physical-mechanical properties (normal state and after accelerated aging).
