An excess of an aqueous solution of an emulsifier in an emulsifier, may be formed not only oriented monomolecular adsorption film asphalt emulsifier supply, and capable of forming a complex multi-layer adsorbent membrane and emulsifier molecules cluster to try to keep a minimum free energy. If the pitch was subjected to high shear into fine particles (0.01mm-0.001mm) and uniform emulsion molecularly dispersed in water, the water is immediately dissolved in the asphalt particles adsorbed interface, resulting in a new adsorption arrangement, lipophilic groups adsorbed on the internal section of the asphalt, the water adsorbed on a hydrophilic group at one end to a fixed clamp at the interface, thereby reducing interfacial tension between bitumen and water. When the emulsifier molecules adsorbed reaches saturation, the surface layer of asphalt particles encapsulated emulsifier molecules have a certain mechanical strength of the solid molecular film, so that asphalt particles having a hydrophilic, stably and uniformly dispersed in water asphalt emulsifier, the formation of emulsified asphalt. Asphalt emulsifier characterized in asphalt emulsifier is a surface active agent by its molecular structure a lipophilic group, and a hydrophilic group composed of a link group. Important parameters to measure the size of the hydrophilic surfactant is a surfactant hydrophilic-lipophilic balance value (HLB). As a water-in-oil type emulsified asphalt emulsifier used is usually required HLB between 8 to 18. In the synthesis of the emulsifier having a molecular characteristics and design, due to the lipophilic group is typically a long chain aliphatic group, a large molecular weight, when the starting material is relatively fixed, the lipophilic moiety offer little change asphalt emulsifier, and The hydrophilic moiety is generally a small molecule, easily modified and converted, so the above formula product conducive estimated hydrophilic-lipophilic balance value.
