Embodiment 1

[0028] Example 1: Weigh a certain amount of the 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.

[0029] Weigh 100g of stone, take a certain amount of water and additives, add it to the iron bowl, mix evenly, then weigh a certain amount of emulsified asphalt, pour it into the iron bowl, stir quickly and fully, and start timing, and the record can be mixed time and molding time.

Abstract

The invention relates to a novel asphalt emulsifier by using rosin, chloropropylene oxide and diethylenetriamine through a two-step reaction, and an optimum reaction technology condition for synthesizing the asphalt emulsifier is obtained. According to the invention, CMC value of a target product is 4.89*10<-4>mol / L, the value is little; and the surface tension under critical micelle concentration is 25.28mN / m. The synthesized emulsifier is the median-cracking type asphalt emulsifier, can be widely 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 an asphalt pavement base layer.

Description

technical field [0001] The invention relates to the organic synthesis and effective utilization of polyalkylamine quaternary ammonium salts, and belongs to the field of chemical organic synthesis. Background technique [0002] In recent years, with the development of the economy, countries all over the world have higher and higher requirements for traffic roads and roads. It is hoped that the built roads can drive various types of vehicles and reduce unnecessary maintenance costs. Especially on fast-moving expressways, the requirements for the driving surface are higher. Experience shows that the pavement made of emulsifier is an ideal pavement material. [0003] For the development of emulsified asphalt, it mainly focuses on how to control the demulsification time of asphalt emulsion and prepare a uniform and stable fine emulsion. Generally, the bitumen content in the emulsion is below 65%, but countries such as France have developed O / W emulsions with a bitumen concentra...
