Embodiment 1

[0029] Example 1: Take a certain amount of emulsifier in a beaker, add 200ml of water, heat to 50-60°C, stir with a glass rod to dissolve it, and adjust the pH to 2-3 with industrial hydrochloric acid. Then weigh 300g of road petroleum asphalt No. 100, and heat it to 110°C to melt it. Start the colloid mill (preheat it with 60°C hot water before starting), inject the emulsifier aqueous solution into the colloid mill, then slowly pour the asphalt into the colloid mill for emulsification, and put the emulsion into the colloid mill for about one minute. Mineral water bottle, close the colloid mill.

Abstract

The invention relates to an optimum reaction technology of novel asphalt emulsifier synthesized by using rosin, chloropropylene oxide and beta-hydroxyethyl ethylenediamine. According to the invention, CMC value of a target product is 4.26*10<-4>mol / L, value is less; surface tension under critical micelle concentration is 29.11mN / m. The synthesized emulsifier is the quick-breaking asphalt emulsifier, and can be used for a bonding layer, a fog sealing layer and solvent-free cold mixing, and can be used for recovery and utilization of asphalt, and stabilization of a bituminous paving base layer.

Description

technical field [0001] The invention relates to the synthesis and effective utilization of an asphalt emulsifier, belonging to the fields of fine chemicals and building materials. Background technique [0002] Bitumen is the residue produced after the distillation of petroleum and coal. Asphalt is used in two forms, emulsified asphalt and hot asphalt. Direct heating of asphalt is hot asphalt. Emulsified asphalt is composed of asphalt, emulsifier, water and other additives. Compared with hot asphalt, emulsified asphalt can be applied at room temperature, has the advantages of better adhesion to stone, low energy consumption and less environmental pollution, and is widely used in roads and waterproofing materials. [0003] Emulsified asphalt is an oil-in-water emulsion, and asphalt emulsifiers can be divided into cationic, anionic, amphoteric and nonionic. Anionic emulsifiers, such as long-chain sulfonates, alkali metal salts of lignin and carboxylates, were mainly used in...
