摘　　要：研究改性白炭黑N98和W99部分替代白炭黑ZEOSIL 165N对天然橡胶性能的影响。结果表明:改性白炭黑N98和W99填充的胶料Payne效应降低,改性白炭黑在橡胶基体中的分散性改善,胶料加工性能好;改性白炭黑N98和W99部分替代白炭黑ZEOSIL 165N对硫化胶的硬度和定伸应力影响较小;改性白炭黑N98和W99结构度低,胶料燃烧产生的烟密度较大。In this study,modified silica N98 and W99 were applied to replace part of the silica ZEOSIL 165N in the natural rubber compounds and the effect of modified silica N98 and W99 on the properties of the compounds was studied.The results showed that,the Payne effect of the compounds filled with modified silica N98 and W99 was reduced,the dispersibility of the modified silica in the rubber matrix was excellent,and the processability of the compounds was good.The modified silica N98 and W99 had little effect on the hardness and modulus of the vulcanizates.The structure degree of the modified silica N98 and W99 was low,and the smoke density in the combustion of the compounds was high.
