Abstract

The possibility of using short cellulose fibers of the Santoweb DX type in the composition of tread rubbers in order to improve their operational characteristics has been studied. An assessment of the effect of the content of short-fiber fillers on the mechanical properties of protector rubbers under static and dynamic loading has been carried out. Cellulose fibers were introduced into rubber mixtures in the form of a 50% concentrate of fibers in natural rubber previously obtained by the method of coextrusion in dosages from 1.5 to 15.0 phr. It has been established that the introduction of fibrous fillers makes it possible to increase the hardness and modulus of tread rubbers at relatively low deformation values while maintaining the strength and elastic characteristics at the level of serial rubber. Acceptable dosages of cellulose fiber concentrates have been determined, which provide an optimal combination of performance indicators for tread rubbers. The introduction of fiber concentrates in dosages of 4.5 and 6.0 phr improves the adhesion characteristics of rubbers, reduces their rolling resistance.
