Abstract
EN This paper presents the results of the mechanical properties and structure of polymer blends modified by dicumyl peroxide (DP) manufactured based on end-of-life vehicle waste. The mixed plastic waste was separated by electrostatic separation. Four types of mixtures were prepared, i.e. waste not subjected to separation, a mixture after one, after two electrostatic separations, and a mixture after two electrostatic separations additionally electrified. To determine the possibility of applying a modifier, dicumyl peroxide was introduced into each mixture. The prepared materials were then subjected to heat pressing, from which standardized test samples were made to evaluate the quality of the produced blends. The mechanical properties were evaluated by static tensile testing, in which the tensile modulus, tensile strength, elongation at maximum strength, and elongation at break were determined. The homogeneity of the blends were evaluated based on the fracture surfaces using scanning electron microscopy (SEM). The results showed that it is possible to use dicumyl peroxide as an effective crosslinking agent for the mixture of polymeric waste from end-of-life vehicles. Subjecting the mixed polymer waste to a double separation process (M2) and introducing dicumyl peroxide into the mixture, provides an increase in strength properties, as well as obtaining the more homogeneous structure compared to the other mixtures tested.
