Regulation of properties of highly filled wood compounds by thermoplastic matrix modifying

Abstract

The current trend of production of new materials substitutes of wood to Republic of Belarus is connected with creation of hi-tech knowledge-intensive production of an environmentally friendly material – the thermoplastic wood and polymeric composite (WPC). The main problem of creation of high-filled DPK is that at introduction of wood fillers the complex of indicators of mechanical and rheological properties, in particular strength characteristics and the composition indicator of fluidity of fusion (IFF) considerably changes. In work DPK samples from chemically modified thermolayer and a wood flour with the raised physicomechanical and rheological characteristics accepted for processing of compositions by methods of molding under pressure and extrusion were received
