CATIONIC EMULSIFIER SYSTEM USABLE IN PREPARATION OF CATIONIC EMULSION OF BITUMINOUS BINDER OF BITUMEN/ POLYMER TYPE

摘要

PURPOSE: To obtain a cationic emulsion of a bitumen/polymer binder excellent in shelf stability and exhibiting rapid and reliable de-emulsification. ;CONSTITUTION: The cationic emulsifier system contains a cationic nitrogenized emulsifier comprising one or more cationic nitrogenized emulsifiers and an auxiliary agent comprising at least one water-soluble salt of a polyfunctional nitrogenized carboxylic acid or an acid that is a precursor of the salt. The salt exhibits sequestering capability corresponding to the fixation of at least 5 mg calcium ions per 1 g salt in the pH range of 3-9 to metal ions.;COPYRIGHT: (C)1994,JPO
