1. Introduction to cationic fast cracking asphalt emulsifier
Cationic fast cracking asphalt emulsifier is a surfactant used for asphalt emulsification, mainly used in the production of high viscosity emulsified asphalt and SBS modified asphalt, suitable for the construction of gravel sealing layer and ultra-thin wear layer. The emulsified asphalt prepared by it has high viscosity, is not easy to flow after spreading, and can form a thick asphalt film on the surface of the aggregate, forming a good adhesion with the stone. Quick cracking asphalt emulsifier (KL-1) is a cationic quick cracking asphalt emulsifier with the characteristics of low dosage and high emulsifying ability. Can be used for emulsification of matrix asphalt and SBS modified asphalt. Especially suitable for the use of fine anti-skid crushed stone sealing layer and ultra-thin cover adhesive layer emulsified asphalt.
