Аннотация

The important scientific direction of petrochemistry is manufacture of plasticizers, softeners,
vulcanizing agents, fillers on the basis of industrial wastes.This allows expand the raw-material base, use heavy
stocks of refinery wastes, reduce technogenic influence on the environmentand solve the problem of manufacture of
import-substituting softeners for the rubber-processing industry of Kazakhstan. The feature of Kazakhstan petroleum
is high concentration of sulfur compounds, in consequence of which much sulfuric wastes are formed, which are
environmentally hazardous in open storage. Optimization of a receipt for developed rubber compounds for
manufacture of a filler strip for passenger car tire beads was carried out in our work by serial analysis of influence of
content of each of the components separately (sulfur and oil sludge) at the fixed amount of other ingredients on the
rubber properties. In order to identify optimal amount of organic share of the oil sludge in the content of rubber
compounds, rubber compounds with different content of organic share of the oil sludge were gained. Plasticizers and
softeners were substituted to the organic share of the oil sludge. Also polymeric and colloidal sulfur mixture of
Tengiz field was used as a vulcanizing agent in the receipts of rubber compounds. The results of comprehensive tests
showed replaceability of traditionally used in the rubber compounds softeners to the organic share of the oil sludge
and use of Tengiz sulfur as a vulcanizing agent.
