Abstract

Currently, the tyre industry is inclining towards the eco-friendly tyres with improved rolling resistance, traction, abrasion resistance and fatigue properties. The present study investigates the potentiality of the hydrogenated styrene butadiene rubber (HSBR), a special and modified grade of styrene butadiene rubber (SBR) as a tyre tread material. The rheological, mechanical, dynamic mechanical, abrasion resistance, fatigue resistance, ageing resistance and ozone resistance of the developed HSBR based composites were critically evaluated and compared with the conventional rubber based compounds, such as natural rubber (NR), emulsion styrene butadiene rubber (ESBR) and solution styrene butadiene rubber (SSBR).Interestingly, it was observed that HSBR based vulcanizates exhibited superior modulus, tensile strength, abrasion resistance, fatigue crack growth resistance, resistance to thermo-oxidative ageing and ozone resistance as compared to the conventional SBRs based vulcanizates. The modulus at 300% elongation of the HSBR based vulcanizate was ∼74% and ∼11% higher than that of the ESBR and SSBR based composites, respectively. Whereas, the improvements in tensile strength were ∼ 88% and ∼64% and the improvements in abrasion resistance were ∼250% and ∼200% than that of the ESBR and SSBR, respectively. The tensile strength and fatigue resistance characteristics of the HSBR vulcanizate were also nearly similar to those of the NR vulcanizate. Thus, this work demonstrates that HSBR can be a potential tyre tread material with robust physico-mechanical properties and durability.

开发具有优异轮胎胎面性能的氢化丁苯橡胶硫化弹性体

目前，轮胎行业正倾向于使用具有更好的滚动阻力、牵引力、耐磨性和疲劳性能的环保轮胎。本研究探讨了氢化丁苯橡胶（HSBR）作为轮胎胎面材料的潜力，氢化丁苯橡胶是丁苯橡胶（SBR）的一种特殊改性牌号。对开发的基于 HSBR 的复合材料的流变性、机械性、动态机械性、耐磨性、耐疲劳性、耐老化性和耐臭氧性进行了严格评估，并与天然橡胶（NR）、乳液丁苯橡胶（ESBR）和溶液丁苯橡胶（SSBR）等传统橡胶基化合物进行了比较。有趣的是，与传统的丁苯橡胶硫化胶相比，基于 HSBR 的硫化胶表现出更高的模量、拉伸强度、耐磨性、抗疲劳裂纹生长性、抗热氧化老化性和抗臭氧性。与 ESBR 和 SSBR 复合材料相比，HSBR 基硫化胶 300% 延伸率时的模量分别高出 74% 和 11%。与 ESBR 和 SSBR 相比，拉伸强度分别提高了 88% 和 64%，耐磨性分别提高了 250% 和 200%。HSBR 硫化胶的拉伸强度和抗疲劳特性也与 NR 硫化胶几乎相似。因此，这项研究表明，HSBR 是一种潜在的轮胎胎面材料，具有良好的物理机械性能和耐久性。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
