近年来,由于对低能耗和低滚动阻力轮胎的要求日益增长,因而用于胎面胶料中的白炭黑也在增多。白炭黑-橡胶技术的4个基本要素,即橡胶聚合物、特殊白炭黑、有效的偶联剂以及适当的混炼技术在轮胎工艺的扩展魔术三角方面是相互关联的:滚动阻力、牵引力(湿路面)和磨耗之间存在着平衡关系。由于白炭黑和橡胶间的极性差别较大,因而与炭黑相比,混炼白炭黑胶料涉及到很多困难。双官能有机硅烷如双(三乙氧基硅丙基四硫化物,TESPT)或其二硫化物通常用作偶联剂,通过对白炭黑表面进行化学改性,最终在白炭黑聚集体和橡胶链之间产生化学键,增强白炭黑
In recent years, there has also been an increase in the use of silica in tread compounds due to the increasing demand for low energy and low rolling resistance tires. White carbon black - The four basic elements of rubber technology, rubber polymer, specialty silica, effective coupling agents, and proper compounding techniques are all interrelated in the extended magic triangle of tire technology: rolling resistance, traction (Wet road) and wear there is a balance between. Due to the large differences in polarities between silica and rubber, there are many difficulties involved in kneading silica fumes with carbon black. Bifunctional organosilanes such as bis (triethoxysilylpropyl tetrasulfide, TESPT) or disulfides thereof are commonly used as coupling agents by chemically modifying the surface of the silica and finally in the presence of silica aggregates and Chemical bonds between the rubber chains, enhanced silica
