Since the implementation of European Union (EU) tire label, the focus of recent attention has been focused on high performance green tire with low rolling resistance, high wet resistance, low noise, and excellent auto‐braking properties. However, it is a significant challenge to simultaneously achieve these performances for rubber materials. In this research, we developed a novel concept on the construction of stable ion bonds for high performance high vinyl polybutadiene rubber (HVBR)‐based dicarboxylate ionomers. HVBR‐based dicarboxylate sodium ionomer (hereafter referred as Na ionomer) was fabricated through complexation reaction of some or all of carboxylic functional groups on the preprepared maleinized HVBR molecular chains with sodium hydroxide. In the case of Na ionomers, the formation of sodium carboxylate group was certified from Fourier transform infrared spectra. Physical and dynamic mechanical measurements indicated that the tensile strength, wear resistance, wet skid resistance, dry sliding resistance, low rolling resistance, and low heat buildup of the Na ionomer were significantly improved compared to that of HVBR, and Na ionomer simultaneously showed better damping properties and the effective damping temperature range was broadened from −8.8 to 30.1°C, which was closer to the room temperature. Consequently, the approach and results collectively represent a significant advance toward the development of high performance green tire rubber materials.

稳定的离子键，可实现高阻尼，高耐湿性和低滚动阻力的高乙烯基聚丁二烯橡胶基二羧酸离聚物

自从实施欧盟（EU）轮胎标签以来，最近的注意力集中在具有低滚动阻力，高耐湿性，低噪音和出色的自动制动性能的高性能生胎上。然而，同时实现橡胶材料的这些性能是一个巨大的挑战。在这项研究中，我们开发了一种基于高性能高乙烯基聚丁二烯橡胶（HVBR）的二羧酸离聚物的稳定离子键构建的新概念。基于HVBR的二羧酸钠离聚物（以下称为Na离聚物）是通过将预先制备的马来化HVBR分子链上的部分或全部羧基官能团与氢氧化钠进行络合反应而制成的。如果是Na离聚物，通过傅立叶变换红外光谱证实了羧酸钠基团的形成。物理和动态力学测量表明，与HVBR相比，Na离聚物的拉伸强度，耐磨性，耐湿滑性，耐干滑性，低滚动阻力和低生热性得到了显着改善，并且Na离聚物同时表现出更好的阻尼性能和有效阻尼温度范围从-8.8扩大到30.1°C，更接近室温。因此，该方法和结果共同代表着高性能生胎橡胶材料发展的重大进步。与HVBR相比，Na离聚物的干滑性，低滚动阻力和低生热性得到了显着改善，并且Na离聚物同时显示出更好的阻尼性能，有效阻尼温度范围从-8.8扩大到30.1°C，接近室温。因此，该方法和结果共同代表着高性能生胎橡胶材料发展的重大进步。与HVBR相比，Na离聚物的干滑性，低滚动阻力和低生热性得到了显着改善，并且Na离聚物同时显示出更好的阻尼性能，有效阻尼温度范围从-8.8扩大到30.1°C，接近室温。因此，该方法和结果共同代表着高性能生胎橡胶材料发展的重大进步。
