SBS改性阳离子乳化沥青的研制

On the Manufacturing of SBS Nature-improved Emulsion of Cationic Bitumen

本文以5-6%的SBS改性沥青为原料,以JY-2型及JY-3型阳离子为乳化剂,以羟基纤维素或羟已基纤维素,氯化钙等为助剂,进行乳化沥青的研制,经实验验证以1.0%JY-2型及1.25%JY-3型阳离子乳化剂、0.3%羟甲基纤维素或羟乙基纤维素、0.2-0.25%的氯化钙可制得相对稳定的SBS改性阳离子乳化沥青。以便为生产、应用SBS改性阳离子乳化沥青提供新技术、新配方、新材料。

A method for manufacturing of a cationic bituminous emulsion is destcried in which 5-6% SBS nature-improved bitumen is emulsified in 1.0% cationic emulsifier of JY-2 type and 1.25% cationic emulsifier of JY-3 type,with 0.3% hydroxymethylcellulose or hydroxyethycellulose or 0.2-0.25% calsium chloride as an aid. The asphalt emulsions manufactured by use of the above materials passed the emulsion stability tests.Thus new materials,new directions and technology are provided for the manufacturing,spreading and application of cationic emulsified asphalt.
