Physico-mechanical and technological characteristics of composite materials based on mixtures of secondary thermoplastics

Abstract

The physico-mechanical and technological characteristics of mixed waste of thermoplastic polymers, including that from the recyclable electronic and electrical equipment based on ABS plastic, were investigated. Target modifying additives were introduced into the composite system to improve the compatibility of polymer components of mixtures and the stable rheological properties of composition during processing. It is established that the secondary polymers behavior in their mixtures is caused by combination of their rheological characteristics and other parameters of mutual compatibility, that has significant impact on phase composition and microphases mutual order. Dispersed additives make a significant contribution to these processes, affecting the structuring of the associated polymer microvolumes. Target regulation of the rheological properties of components will ensure the achievement of acceptable and reproducible physico-mechanical characteristics and technological parameters of process, which will create prerequisites for the production of competitive products with a high guaranteed service life without use of scarce raw materials. Composite materials have been developed that are adapted to stable processing by extrusion, injection molding, and formation molding into technical products with acceptable performance characteristics.
