Vulcanizate Structure of Isoprene Chloroprene Rubber Combination

摘要

The physical and mechanical properties of vulcanizates and rubber articles are determined largely by the interface polymer interactions in these systems. The interface interactions were evaluated by the methods of hydrostatic suspension and stratification of plied-up vulcanizate samples. The hydrostatic suspension permits assessment of the rubber interface interactions and of quantitative method change in the degree of crystallinity associated with changes in one specific volume of the vulcanizates with stretching. The increase of a specific volume is accompaned by the formation of vacuoles around the second phase particles in the rubber medium. The decrease in specific volume is explained by crystallization. In order to decrease the effect of undissolved ingredients in the rubber by the specific volume of the vulcanizate SKI-3, the proportion of SKI-3 combining the PH in the formation of the rubber mixture, and the zinc oxide content were reduced. The vulcanizate strength was then determined, yielding more accurate data on the degree of modification of the crystallinity of the rubber.
