Experimental and statistical studies of the effect of pressing time on the swelling and mechanical properties of the radial tyre tread compound
Cars are the most important mode of transportation and play a significant role in the development of modern communities. Tyres, one of the main components of cars, hold strategic importance. Therefore, research aimed at improving the quality and increasing the production speed of tyres is an integral part of the strategic policy on this subject. In this study, the effects of pressing time in curing press (time of curing with pressure) on the structural properties of radial tyre tread were investigated. According to the one-factor response surface methodology, 10 samples that had different pressing times during their curing press were produced. The swelling test was used to study the cured compound structure. In this way, essential parameters such as diffusion coefficient and crosslinking density were calculated. The results showed that the vulcanised samples in free pressure conditions had the lowest amounts of crosslinking density. Also, these samples had the highest intrinsic diffusion coefficient. It is also observed that the intrinsic diffusion coefficient and crosslinking density have a relationship with pressing time. Mechanical tests were also performed to determine the dependence of the mechanical properties of the tyre tread on the duration of pressing time. As an obvious result, the cured samples in zero-pressure conditions had the lowest tensile strength, tear strength, hardness and the highest amount of resilience percentage. However, the abrasion parameter had the most negligible dependence on the pressing time. The results showed the dependence of the swelling and mechanical properties of the tread tyre compound on the pressing time. So, according to the optimal targeting for different variables and results, the optimal time of applying pressure during curing for the tyre tread compound has been obtained. As an important result, in the curing process, the pressurising can be stopped after about 14 min while the curing continues only with heat.
期刊介绍：
The Journal of Rubber Research is devoted to both natural and synthetic rubbers, as well as to related disciplines. The scope of the journal encompasses all aspects of rubber from the core disciplines of biology, physics and chemistry, as well as economics. As a specialised field, rubber science includes within its niche a vast potential of innovative and value-added research areas yet to be explored. This peer reviewed publication focuses on the results of active experimental research and authoritative reviews on all aspects of rubber science.
The Journal of Rubber Research welcomes research on:
the upstream, including crop management, crop improvement and protection, and biotechnology;
the midstream, including processing and effluent management;
the downstream, including rubber engineering and product design, advanced rubber technology, latex science and technology, and chemistry and materials exploratory;
economics, including the economics of rubber production, consumption, and market analysis.
The Journal of Rubber Research serves to build a collective knowledge base while communicating information and validating the quality of research within the discipline, and bringing together work from experts in rubber science and related disciplines.
Scientists in both academia and industry involved in researching and working with all aspects of rubber will find this journal to be both source of information and a gateway for their own publications.
