The influence of recipe ingredients of elastomeric composition on the elastic-deformation properties of tire

Abstract

The results of researches of elastomeric compositions on the basis of the natural rubber, containing a Vulcuren VPKA-9188 are given in this paper. Thisingredient use as substitute of the accelerator of sulfuric curing of DFG. The addition of the componentallows to lower aniline allocation at rubber usage, to carry out vulcanization with high speed and practically without reversion. It is established that addition of various vulcanization systems to rubber mixes influences technical properties of vulcanizates. The parameters of the crack growth resistance to the repeated flexing differ in 1.1–1.4 times. Such distinction probably is connected with the nature and density of the cross-linking bonds which are forming in volume of elastomeric composition in the course of curing. Application of studied ingredient in serial elastomeric composition of tire rubbers demands correction of composition and dosage of vulcanizing system.
