elastomeric composition

Peculiarities of formation of technological, vulcanization, dynamic, relaxation, and physicomechanical properties of elastomeric composition used for the tread production have been studied in the presence of bioingredient as a plasticizer-softener. Bioingredient is an organic component of sunflower oil winterization by-product (OSSO product). It was found that the OSSO product increases the cohesive strength of the rubber compound by 1.5 times in comparison with the industrial petrochemical lubricants.

In this work the synthesis technology of zinccontaining polymer - inorganic composite on the basis of products of secondary raw material processing at joint precipitating with carbamide and formaldehyde (ZnCFO) is described. The structure and properties of ZnCFO are investigated by the differential-thermal analysis, electronic microscopy, and IR-spectroscopy. The action of ZnCFO as vulcanization active component of elastomeric compositions on the basis of rubbers of general and special purpose with various vulcanization systems is investigated.

The influence of composite component perlite DPh-Zn, that is the waste of oil refining industry, on the formation of properties complex of rubber mixes and their vulcanizates on the basis of apolar cis-1,4-polyisoprene and butadiene-nitrile rubbers of various polarity has been investigated. It has been established that perlite DPh-Zn is the effective vulcanization active component of multifunctional action capable at 10.0 mass frac.
