Abstract
In this study the functional properties and the production process of PVC matrix composites used in the technology of a new type of pro-environmental noise barriers for use in road construction, sound shielding of urban settlements, bridges, railroad tracks were described. PVC matrix composites were obtained by stirring extrusion using a single-screw extruder. The samples for mechanical tests, flame resistance and aging tests were obtained in the form of barrels and paddles using an injection molding machine. Based on the test results, it was found that the developed PVC composites have the following properties: Charpy impact strength greater than 12 kJ/m2, hardness according to Rockwell exceeding 78 N/mm2, oxygen index equal to 50% and good UV resistance at 3000 h. An important advantage of these composites is the agro-food waste content of 30 wt%, which makes the materials environmentally friendly.
