Resource-saving polymer compositions for construction purposes

Abstract

The paper presents the results of the application of building materials based on thermoplastic (polyvinyl chloride) and thermosetting (urea-formaldehyde) polymers of industrial waste as fillers instead of traditional ones that allow solving resource saving issues. Polyvinyl chloride materials of profile molded products with increased strength by 1.5-2 times were obtained by replacing 50% of the traditional "chemically precipitated chalk" filler with waste from water treatment of thermal power plants. The strength of heat-insulating foams based on urea-formaldehyde resin is increased 3 times by introducing only 0.2 m.p. carbonate water treatment waste per 100 m.p. resins in the binder. The effect is achieved through the implementation of the principle of "condensation" filling of polymer matrices. In polymers of different chemical nature, during filling, the mechanisms of matrix reinforcement associated with the activity of the surface of the filler particles are realized. They are proposed for the practical implementation of the formulation and production technology of profile and sheet materials, as well as heat-insulating foam plastic.
