Abstract

The influence of nature and dosages of rosin-terpene-styrene-maleic adducts on the rheological, relaxation and adhesive properties of filled elastomer compositions has been studied. The studied ingredients were introduced into filled tire compositions based on a combination of synthetic polyisoprene and polybutadiene rubbers in equivalent dosages with an industrial tackifier, pine rosin. Rosin-containing additives were obtained by treating a mixture of turpentine and styrene with maleic anhydride at temperature of 90 ± 5°C, followed by distillation of the residues of unreacted components. It has been determined that with an increase in the content of aromatic substituent in rosin-terpenostyrene-maleic adducts, the Mooney viscosity of rubber compounds increases to 13.0%; at the same time, an increase in the dosage of the studied additives has practically no effect on the viscosity index (the change is not more than 4.5%). It was shown that a change in the values of the relaxation coefficients of rubber mixtures with experimental additives and an industrial tackifier will not have a significant impact on the technological process of processing mixtures. For filled rubber compounds with rosin-containing additives, there is a tendency to increase the confection properties with an increase in the storage time of the mixtures in comparison with the sample containing pine rosin. When storing mixtures with rosin-terpene-styrene-maleic adducts for 5–7 days, the tack of the samples increases by 5.7–29.0%, which will increase the time interval for storing rubber compounds.
