Abstract

Abstract The article presents and describes in detail the physical picture of the process of forming the created wood-polymer insulation material in vacuum. It is proved that the developed material is a multicomponent system in which wood particles form a strong adhesive bond with a polyurethane foam matrix, characterized by complex physical and chemical reactions that occur in the process of interaction of all components of the system. Since the process of forming polyurethane foam occurs in the presence of wood filler, its influence on the process of gas phase formation during polymer foaming was studied. The main technological parameters affecting the formation of strong intermolecular bonds and the interaction of the components of wood-polymer insulating material with each other are revealed. In particular, it was found that the process of polymerization of polyurethane foam in the presence of wood filler under vacuum allows one not to deform or destroy the gas-structural elements during their formation. Also, basing upon the results of experimental studies, the dependence of the influence of wood filler moisture on the process of structure formation of the created material was established.
