A precipitated silica pre-treated with organosilane bis[3-(triethoxysilyl)propyl]tetrasulphide (TESPT) was produced using an industrially applicable ball milling coupled with oven heating method. The effectiveness of silanisation on the silica that reacted with TESPT via the unique preparation method was characterised by fourier transform infrared (FTIR), scanning electron microscope (SEM), water dispersal, bound rubber content (BRC), mixing and compound behaviours compared to an untreated silica. The silanisation reactions were effectively realised and the dispersion of the pre-treated silica in rubber matrix was improved after the silica was processed through multiple stages two-roll-mill mixing in producing a pre-treated silica masterbatch (PSiMB). Subsequently, various dosages of the PSiMB were loaded into an industrial rubber compound. The physical, cure and mechanical properties of the vulcanisates were investigated. It was observed that the cure initiation, hardness, crosslink density and mechanical properties of the vulcanisates were enhanced after the rubber compounds were reinforced using the PSiMB.

球磨制备的硅烷预处理二氧化硅及其对工业橡胶胶料的增强作用

使用工业上可应用的球磨结合烤箱加热方法,制备了用有机硅烷双[3-(三乙氧基甲硅烷基)丙基]四硫化物(TESPT)预处理的沉淀二氧化硅。与傅立叶变换红外光谱(FTIR),扫描电子显微镜(SEM),水分散性,胶结橡胶含量(BRC),混合和胶料行为相比,通过独特的制备方法与TESPT反应的二氧化硅具有硅烷化作用。未经处理的二氧化硅。有效地实现了硅烷化反应,并且在生产预处理的二氧化硅母料(PSiMB)的过程中,通过多步两辊混炼法处理二氧化硅后,可以进一步改善预处理的二氧化硅在橡胶基质中的分散性。随后,将各种剂量的PSiMB装入工业橡胶混合物中。研究了硫化橡胶的物理,固化和机械性能。观察到,在使用PSiMB增强橡胶混合物后,硫化胶的硫化引发,硬度,交联密度和机械性能均得到增强。
