In this work, the effects of using feldspar (FLD) as an alumina-silicate inorganic filler, with carbon black (CB) as a novel binary filler system, on the properties of SBR compounds were investigated for tire applications. The bis(triethoxysilylpropyl) disulfide (TESPD) was used for modification of FLD. The SBR hybrid composites were produced by replacing 10 phr of CB filler with neat FLD and functionalized FLD (F-FLD). The TESPD was added directly to the rubber mixture including neat FLD. The SBR composite which has only CB filler (50CB) was found to have the highest damping parameter (tan δ) value at 60°C. On the other hand, the composites loaded with the CB and the FLD fillers exhibited relatively lower tan δ at the same temperature showing lower rolling resistance meaning better fuel saving performance. The lowest rolling resistance was achieved for the 40CB-10F-FLD most probably due to its stronger interaction with the SBR elastomer molecules through the silane agent-assisted crosslinks of the F-FLD. As another dynamic property, the storage moduli at −20°C were found to be lower for the SBR hybrid composites as compared to that of the 50CB composite, exhibiting enhanced winter traction performance of the composites having FLD filler together with CB. The composites containing only 10 phr of FLD and F-FLD, on the other hand, exhibited very low tensile strength values which are not acceptable for tire tread materials.

在这项工作中，研究了将长石（FLD）用作氧化铝-硅酸盐无机填料，炭黑（CB）作为新型二元填料体系对轮胎应用SBR胶料性能的影响。将双（三乙氧基甲硅烷基丙基）二硫化物（TESPD）用于FLD的改性。通过用纯净的FLD和功能化的FLD（F-FLD）代替10 phr的CB填料来生产SBR杂化复合材料。将TESPD直接添加到包括纯FLD的橡胶混合物中。发现仅具有CB填料（50CB）的SBR复合材料在60°C时具有最高的阻尼参数（tanδ）值。另一方面，负载有CB和FLD填料的复合材料在相同温度下显示出相对较低的tanδ，显示出较低的滚动阻力，意味着更好的节油性能。40CB-10F-FLD的滚动阻力最低，这很可能是由于它通过F-FLD的硅烷试剂辅助交联与SBR弹性体分子的相互作用更强。作为另一动态特性，发现与50CB复合材料相比，SBR杂化复合材料在-20°C下的储能模量较低，具有FLD填料和CB的复合材料表现出增强的冬季牵引性能。另一方面，仅含有10phr FLD和F-FLD的复合材料表现出非常低的抗张强度值，这对于轮胎胎面材料是不可接受的。与50CB复合材料相比，发现SBR杂化复合材料在-20°C时的储能模量较低，具有FLD填料和CB的复合材料表现出增强的冬季牵引性能。另一方面，仅含有10phr FLD和F-FLD的复合材料表现出非常低的抗张强度值，这对于轮胎胎面材料是不可接受的。与50CB复合材料相比，发现SBR杂化复合材料在-20°C时的储能模量较低，具有FLD填料和CB的复合材料表现出增强的冬季牵引性能。另一方面，仅含有10phr FLD和F-FLD的复合材料表现出非常低的抗张强度值，这对于轮胎胎面材料是不可接受的。
