摘要: 通过对两种自制乳化剂A,B界面扩张模量及所制备乳化沥青Zeta电位的测定,考察了界面扩张模量和Zeta电位与乳化沥青稳定性之间的关系。当自制乳化剂A,B浓度分别为100mg/L,50mg/L时,界面膜弹性最大。当乳化剂A,B掺量分别为2.8%、1.2%时,所制备乳化沥青Zeta电位绝对值最大,储存稳定性最佳。因此,界面扩张模量、Zeta电位与乳化沥青储存稳定性有着良好的对应关系,故二者可作为评价乳化剂优劣及确定乳化剂最佳用量的指标。

Abstract: The relationship among interfacial dilatational modulus, zeta potential and the stability of emulsified asphalt was investigated by measuring interfacial dilatational modulus and zeta potential of self-made emulsifier A and B. When the concentration of self-made emulsifier A and B was 100 mg/L and 50 mg/L respectively, the elasticity of interfacial film was the largest. When the dosage of emulsifier A and B was 2.8% and 1.2% respectively, the emulsified asphalt presented the maximum Zeta potential absolute value and the best storage stability. Thus, the interfacial dilatational modulus and zeta potential has a good correspondence to the storage stability of emulsified asphalt, so both can be used as an indicators of evaluation of the emulsifier merits and determination of emulsifier optimal dosage.

Key words: highway engineering, interfacial dilational rheology, zeta potential, storage stability
