采用Zeta电位仪和沥青标准粘度计等仪器,通过对乳化沥青Zeta电位及标准粘度的测量,探讨了不同稳定剂系统对透层用阳离子乳化沥青储存稳定性的影响机理.研究结果表明:CaCl2主要影响乳化沥青的Zeta电位,羧甲基纤维素钠(CMC)主要影响乳化沥青的标准粘度,两者都能提高乳液的储存稳定性;且当两种稳定剂混合使用时,比单一使用稳定效果佳.

The effect of different kinds of stabilizer on the storage stability of quaternary ammonium cationic emulsified asphalt was discussed by investigating the Zeta potential and normal viscosity.The test results show,that CaCl2 increasing the storage stability is mainly because of the influence on the Zeta potential.On the other hand,Carboxymethyl Cellulose（CMC） increasing the storage stability is mainly because of the increase of the normal viscosity of the emulsion.By using the mixture of CaCl2 and CMC,...
