Liquid amine composition for emulsifiers for bitumen

摘要

The present invention provides a liquid amine composition for an emulsifier for bitumen which can impart, to a bituminous emulsion, more excellent emulsifying stability and adhesive properties to aggregates than conventional products. The liquid amine composition for the emulsifier for bitumen of the present invention comprises (1) 5 to 70% by weight a monoamine having an aliphatic hydrocarbyl group of 8 to 22 carbon atoms, (2) 20 to 80% by weight of a polyamine having an aliphatic hydrocarbyl group of 8 to 22 carbon atoms, and (3) 10 to 75% by weight of an organic acid of 4 to 18 carbon atoms.
