STUDYING THE STRUCTURAL AND PHYSICAL PROPERTIES OF POLYVINYL CHLORIDE THAT IS ENCASED WITH MINERAL FILLERS

Abstract

The problem's origin. Numerous scientific studies on the application of mineral fillers in the creation of composite materials are currently being carried out in our Republic. One of the most crucial responsibilities of the modern period is the employment of mineral fillers to shield polymer materials and constructions from fire and other harsh conditions.Purpose of work. The purpose of the work is to obtain thermally stable and mechanically strong thermoplastic composite materials by filling polyvinyl chloride with basalt mineral.
Methodology. Physico-mechanical properties of polypropylene compositions filled with oligomers containing nitrogen, phosphorus and metal, bending resistance, impact resistance were determined by the Sharpie method, and the fluidity index was determined by the viscometry method.Scientific news. Physico-mechanical and thermophysical properties of polyvinyl chloride filled with basalt fibers were studied.The results obtained. To obtain composite materials based on basalt mineral from polyvinyl chloride, the amount of filler was taken from 1 mass part to 5 mass parts. The physico-mechanical properties of the obtained composite materials showed that an increase in the amount of filler leads to a decrease in the fluidity of the material. Based on the results, the optimal amount of basalt-containing fillers in the composite material is 5 parts by mass.Combustion properties of the obtained materials were determined according to the oxygen index, thermophysical properties according to the DTA method.
