摘要
SBS乳化改性沥青因其优良的渗透性、抗疲劳性和防水性已得到广泛的应用,但是为了解决SBS与沥青相容性的问题,需要制备性能良好的SBS乳液。选择了三种阳离子乳化剂以及非离子和阴离子乳化剂,按不同的比例分别考察了阳离子乳化剂与非离子、阴离子乳化剂复配时对SBS的乳化效果,同时也和阳离子乳化剂单独使用时的乳化效果进行了对比。试验结果表明:单一的阳离子乳化剂对SBS的乳化效果不如复配乳化剂得到的效果好;阳离子、非离子、阴离子三种类型的乳化剂按质量比为3:1:1复配时对SBS乳化效果最好,但其对乳液的稳定性贡献不大,在此基础上加入一定量的稳定剂,可以制备出性能优良的SBS乳液。
SBS emulsified modified asphalt has been applied widely due to its excellent permeability,fatigue resistance,and water resistance.In order to resolve the compatibility problem between SBS and asphalt, it is necessary to produce SBS emulsion with good performance.Three different cationic emulsifiers,one anionic emulsifiers,and one nonionic emulsifiers were selected to study the impact of compounded emulsifiers on the emulsifying properties of SBS.Meanwhile,the emulsion effect of each cationic emulsifier was ...
