Effect of Silica Modifiers on Properties of Silica Filled NR Compound

FU Wen;Li Meishu;Wang Li;Guangdong University of Petrochemical Technology;  
In this study,the effect of silane coupling agent(coupling agent Si69 and KH570)and surfactant [polyethylene glycol(PEG) and 1-octadecanol] as silica modifiers on the properties of silica filled NR compound was investigated. The results showed that,compared with the compound without modifier,the curing rate of the compound with modifier increased and filler's framework was lowered,the crosslinking density of the vulcanizates with silane or PEG increased,the modulus at 300% elongation,tear strength and abrasion resistance of the vulcanizates increased,the tensile strength of the vulcanizates with silane increased while that with PEG or 1-octadecanol decreased,the bound rubber content of the compound with silane coupling agents or 1-octadecanol increased. It was concluded that addition of modifiers improved the silica dispersion and interaction between silica and rubber matrix,and the best results were obtained using coupling agent Si69.
