FIELD: waste polymers.
SUBSTANCE: invention relates to the field of processing waste polymers, in particular when obtaining composite materials using secondary raw materials - polyethylene terephthalate, and can be used in various industries. A composite material based on recycled polyethylene terephthalate is described; low molecular weight polyisobutylene and basalt flour, molybdenum disulfide with the following ratio of components, wt.%: 70 secondary polyethylene terephthalate, 15 low molecular weight polyisobutylene, 10 basalt flour, 5 molybdenum disulfide are used as functional additives.
EFFECT: development of the composition of a composite material based on recycled polyethylene terephthalate to obtain a material with improved physical and mechanical properties, such as friction coefficient, wear resistance, hardness, due to the introduction of modifying functional additives.
