摘要
研究了硅烷偶联剂(TESPT)与低共熔溶剂(DES)协同改性白炭黑对作为胎面胶的天然橡胶复合材料性能的影响。用傅里叶变换红外光谱分析了TESPT和DES与白炭黑之间的相互作用,用橡胶加工分析仪和扫描电镜分析了白炭黑之间的相互作用,并测试了复合材料的硫化特性、力学性能和耐磨性,通过动态力学分析仪考察了其滚动阻力和抗湿滑性能。结果表明,TESPT与DES的协同改性能够改善白炭黑在天然橡胶中的分散性,提高复合材料的硫化速率、力学性能和耐磨性,降低滚动阻力。当TESPT和DES的用量均为1份(质量)时,天然橡胶复合材料在具备较低滚动阻力的同时能够保持较好的抗湿滑性能。
The effect of silica modified by silane coupling agent(TESPT)and deep eutectic solvent(DES)on the properties of natural rubber(NR)composites as tread rubber was studied.The interaction between TESPT,DES and silica was analyzed by Fourier transform infrared spectroscopy,the interaction between silica and silica was analyzed by rubber processing analyzer and scanning electron microscope,the curing characteristics,mechanical properties and wear resistance of the composites were determined,and the rolling resistance and wet skid resistance were investigated by dynamic mechanical analyzer.The results showed that the synergistic modification of TESPT and DES could improve the dispersion of silica in NR,increase the vulcanization rate,improve the mechanical properties and wear resistance of the composites,and reduce the rolling resistance.When the amounts of TESPT and DES were 1 phr(mass)respectively,the NR composites had lower rolling resistance and better wet skid resistance.
