ASPHALT MIXTURE ADHESION PREVENTIVE AGENT

摘要

PROBLEM TO BE SOLVED: To provide an asphalt mixture adhesion preventive agent easily sliding down an asphalt mixture on a back of a dump truck and the like even with a condition having small inclination angle, hardly staining a contact surface of the back, excellent in residual property of liquid on the back, and excellent in stability at ordinary temperature or low temperature after dilution with water.;SOLUTION: There is provided an asphalt mixture adhesion preventive agent containing a compound (A) represented by the formula (1) and an anionic surfactant having a hydrocarbon group or an acyl group having 8 to 18 carbon atoms, and sulfonate or sulphate (B), and having each mass ratio of (A) and (B) of (A) 90 to 98 mass% and (B) 2 to 10 mass%. R¹O-(EO)_m(PO)_n-R² (1), where R¹ is a hydrocarbon group having 1 to 4 carbon atoms, R² is a hydrogen atom or a hydrocarbon group having 1 to 4 carbon atoms, EO is an oxyethylene group, PO is an oxypropylene group, m is the average addition mole number of the oxyethylene group, n is the average addition mole number of the oxypropylene group, m+n is 2 to 25, and the content of EO to the total content of EO and PO is 40 to 100 mass%.;COPYRIGHT: (C)2015,JPO&INPIT
