Analysis of the properties of the mixture’s components on the basis of construction and polymeric materials waste

Abstract

Abstract The paper presents the technologies of obtaining composite structures on the basis of secondary polymeric and construction materials filled with coordination compounds, got by the mixture’s coextrusion through the coextrusion head as well as by the extrusion pressing-out through the fillister head. It has been found out that with the decrease in the size of the layer’s boundary and with the increase of the layers’ durability the friction coefficient diminishes. Besides, reaching the friction coefficient’s value at the established stage happens during a longer period than for a single-layer structure. The value of the tear-and-wear for a multilayer composite structure is much less than for a single-layer one. A multilayer composite structure is recommended to be used as an antifriction material under low pressures at a high slip velocity. It is demonstrated that due to the addition of the filler on the basis of coordination compounds into separate layers during the coextrusion molding it is possible to obtain the material with the improved wear resistance.
