摘 要:通過(guò)絮凝沉降法制備了木質(zhì)素/蒙脫土復合物(CLM),將其跟丁苯橡膠(SBR)機械共混制備了SBR/CLM復合材料,并對其微觀(guān)結構、硫化特性、交聯(lián)密度、力學(xué)性能、熱氧老化性能以及熱穩定性進(jìn)行研究。結果表明:木質(zhì)素與蒙脫土的相互作用提高了CLM與SBR相容性;隨著(zhù)CLM用量的增加,焦燒時(shí)間與正硫化時(shí)間逐漸增加,復合材料的力學(xué)性能逐漸增大,老化性能及熱穩定性也得到改善。

Abstract:Complex of lignin and montmorillonite(CLM) prepared by coagulation and precipitation,was used to reinforce styrene-butadiene rubber(SBR)by mechanical blending,and the microstructure,the curing behavior,the crosslinking density,the thermal properties,the thermal oxidative ageing properties and the mechanical properties of SBR/CLM composites were investigated. The results showed that the compatibility of SBR and CLM were improved through the interaction between lignin and montmorillonite. With increasing the filler loading,the scorch time,the optimum cure time and the mechanical properties were increased. Thermal properties and thermal oxidative ageing properties,in general,were also improved with loading of this novel filler.
Key words:styrene-butadiene rubber;complex of black liquor and montmorillonite;composites
