| 摘 要：通過(guò)絮凝-酸沉降法制備了一種復合補強劑——黑液-硅藻土共沉物（CLD），將其分別與丁腈橡膠（NBR）和丁苯橡膠（SBR）機械共混制得NBR／CLD與SBR／CLD復合材料�？疾炝薈LD的含量對橡膠復合材料硫化特性、交聯(lián)密度、力學(xué)性能、熱氧老化性能以及熱性能的影響。結果表明：隨著(zhù)CLD的加入，焦燒時(shí)間與正硫化時(shí)間逐漸降低，硫化速度逐漸提高；交聯(lián)密度逐漸增加；力學(xué)性能逐漸增強；但老化性能及熱性能沒(méi)有得到改善。 |

| Abstract：A synthetic reinforcing agent，co-precipitate of lignin and diatomite（CLD） was prepared by means of coagulation and acid precipitation，and then acrylonitrile-butadiene rubber（NBR）／CLD and styrene-butadiene rubber（SBR）／CLD composites were prepared by blending NBR or SBR with CLD under mechanical mixing. The effects of the loading of CLD on curing characteristics，cross-linking densities，mechanical properties，thermal properties and thermo-oxidative ageing properties were evaluated. The results showed the scorch time and optimum cure time were reduced and a remarkable enhancement in cross-linking densities and mechanical properties was observed，however，the thermal oxidative ageing properties decreased with the increase of CLM loading. |
