TECHNOLOGICAL ASPECT OF PRODUCTION AND USE OF OIL-OLIGOMERIC ADDITIVE ON BASIS OF SECONDARY OLIGOMERS IN PRODUCTION OF EMULSION RUBBER

Abstract

The paper shows the perspective direction of using by-products and wastes of the petrochemical industry in the production of rubber products. It was revealed that oligomers synthesized from petrochemical by-products can be used as promising additives. The technological aspects of the use of additives based on PN-6 oil and its combination with an oligomer synthesized from by-products of polybutadiene production in the technology of obtaining filled emulsion rubbers were studied. It has been found that the best way to combine oligomeric additives with the matrix of synthetic rubbers is to introduce them into latex in the form of dispersions. The influence of coagulants of different nature on the process of emulsion rubber release filled with oil oligomeric anthioxidant dispersion was investigated. It was found that the change in the mass ratio of oil-oligomeric-anthioxidant dispersion components did not significantly affect the consumption of the coagulant used. It has been shown that the introduction of an oil-oligomeric-anthioxidant additive into the elastomeric compositions at the stage of their creation provides an even distribution of the components in the rubber matrix. The effect of manufactured additives on the properties of the resulting composites was estimated. It has been found that vulcanizates obtained on the basis of rubber with a high content of oligomeric component in the composition of the additive have a higher resistance to thermal oxidative aging. Increasing the stability of vulcanizates to the thermal and oxidative effects indicates a decrease in the losses of the antioxidant in the process of obtaining rubbers and elastomeric compositions. It is shown that the introduction of oily oligomerically antioxidant dispersion in latex at the stage of creation of elastomeric compositions makes it possible to improve the technical and economic efficiency and environmental friendliness of their production. Evaluation of the effect of manufactured oligomeric additives on the properties of the resulting composites revealed their multifunctionality.Forcitation:Pugacheva I.N., Nikulina N.S., Nikulin S.S.
