The Effect of Novel Binary Accelerator System on Properties

Different studies were conducted on binary accelerator systems via different approaches [3–5]. The objective of the present study is to evaluate the effect of a new binary system based on Cystine (Cys) and N-cyclohexyl-2-benzothiazyl sulfenamide (CBS) in conventional vulcanization system of natural rubber (NR).

Studies on New Binary Accelerator Systems in Rubber Vulcanisation

Our study involves the investigations on different systems of vulcanisation of elastomers or their blends using new binary accelerator combinations. In this context we thought it worthwhile to deal in some detail on the use of vulcanising agents, accelerators, fillers etc. in rubber vulcanisation. 1.1 VULCANISING (CURING) AGENTS

Sulphur Vulcanisation of Styrene Butadiene Rubber using New

The synthesis and use of a new compound (DTB) in natural rubber has been reported in our previous studies [2]. It has been found that DTB functions as a binary accelerator,which speeds up the cure reaction and improves the mechanical properties of NR vulcanisates. The present paper discusses the influence of this new binary accelerator

Studies on double networks in natural rubber vulcanizates

The concept of double networks is a rather new idea, by which one imparts chain orientation in elastomers. Double networks were made in natural rubber vulcanizates cured with a single and a new binary accelerator system. Double networks with different extensions were prepared and their effects on tensile properties were analyzed.

Studies on a New Binary Accelerator System for the Sulfur

The chemical reactions involved when a binary accelerator system is used in rubber vulcanization varies with the systems used. The exact mechanism of these reactions is not fully understood even now. Accelerators in which sulfur is combined as S—S, C—S—C, or S—N are generally inactive at low vulcanization temperatures because of the

These binary systems were found to be very effective in reducing the optimum vulcanization time. Also it was noted that 1‐phenyl‐2,4‐dithiobiuret, which is more nucleophilic, is more reactive (as observed from the reduction in optimum cure time) as a secondary accelerator, indicating a nucleophilic reaction mechanism in the vulcanization

The result of the study points out that the proposed system can be active in NR regardless of the vulcanization recipe and temperature. The performance of the new binary system in filled vulcanizates is also studied. Based on the processing, mechanical and chemical characterization an optimum concentration is suggested for the new system.
