Filler impact on the properties of energy-efficient polymer glass composite material

Abstract

This paper presents the research results of the influence of the filler amount impact on the basic physical, mechanical and operational properties of energy-efficient polymer composite material for external and internal wall cladding of buildings and structures. The raw material mixture contains sheet window glass cullet used as filler and non-plasticized polyvinyl chloride waste dissolved in methylene chloride used as binder. Products based on this mixture can be produced by cold pressing method followed by heat treatment at the methylene chloride boiling point. Judging by the research results, it was discovered that the increase in the filler content causes the increase of its density, thermal conductivity, water absorption, total and open porosity alongside frost resistance reduction. The compressive and bending strength is enhanced by increasing the filler content up to 40 wt%, but further increase of the cullet amount causes its decline due to the lack of the binder. Basing on the received dependences, the chosen filler content equaled 40 wt%, as it provides not only maximum strength for this composition, but also allows producing material with energy-efficient thermal characteristics. Water absorption and frost resistance at the stated filler contents are at the level allowing to use the developed composite material both for interior and exterior walls cladding combining the functions of the facing and insulating layers at multi-layer walls constructing.
