INFLUENCE OF FILLER ON PROPERTIES OF COMPOSITE MATERIAL MADE FROM GLASS AND PLASTIC WASTES
This article presents the results of the influence of the amount of filler on the basic physicomechanical and operational properties of the polymer composite material for external and internal lining walls of buildings and construction. As a filler, the raw material mix contains a broken of sheet window glass, and as a binder – unplasticized polyvinyl chloride waste, dissolved in methylene chloride. Products based on this mixture can be obtained by cold pressing, followed by heat treatment at the boiling point of methylene chloride. Based on the results of the research it was established that an increase in the filler content leads to an increase in density, thermal conductivity, water absorption, total and open porosity, while reducing frost resistance. The strength of compression and bending increase with the filler content up to 40 wt.?%, and with a further increase in the amount of cullet begin to decline due to the shortage of a binder. On the basis of the dependences obtained, the filler content was chosen to be 40 wt.?%, which provides not only the maximum strength for a given composition, but also allows obtaining an energy-efficient material with respect to heat engineering characteristics. Water absorption and frost resistance at the specified filler content are at a level that allows using the resulting composite material for both internal and external wall cladding of buildings and structures.
