Title:
DECOMPOSER FOR ASPHALT EMULSION
Document Type and Number:
Japanese Patent JP2017122352
Kind Code:
A
Abstract:
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
