DECOMPOSER FOR ASPHALT EMULSION
PROBLEM TO BE SOLVED: To provide a decomposer that has an excellent instant decomposition property of cationic asphalt emulsion having high storage stability and mechanical stability and, at the time of spraying, makes decomposition progress not only to surface layer part at which the decomposer is in contact with asphalt emulsion but also to lower layer part at which the decomposer is not in contact.SOLUTION: There is provided a decomposer of cationic asphalt emulsion, the decomposer including a sulfur-containing anionic surfactant and inorganic sulfate and/or condensed phosphate and having specific gravity of 1.03 to 2.00 at 20°C. Preferably, the decomposer has viscosity equal or lower that 500 mPa s at 20°C. Preferably, the sulfur-containing anionic surfactant contains at least one type selected from an alkyl sulfonic acid, alkylsulfonate, alkylbenzenesulfonic acid, and alkylbenzenesulfonate.SELECTED DRAWING: None
【課題】貯蔵安定性、機械的安定性の高いカチオン系アスファルト乳剤の即時分解性に優れかつ、散布時に分解剤とアスファルト乳剤が接触した表層部分だけでなく、非接触の下層部分まで分解が進行する分解剤を提供する。【解決手段】含硫黄型アニオン性界面活性剤と無機硫酸塩及び／又は縮合リン酸塩とを含み、２０℃における比重が１．０３〜２．００であるカチオン系アスファルト乳剤の分解剤。２０℃における粘度が５００ｍＰａ・ｓ以下であると好ましい。前記含硫黄型アニオン性界面活性剤が、アルキルスルホン酸、アルキルスルホン酸塩、アルキルベンゼンスルホン酸及びアルキルベンゼンスルホン酸塩から選ばれる少なくとも１種を含むと好ましい。【選択図】なし
