Problems solved by technology

Through research, it is found that quaternary ammonium salts with carbon chains less than 14 in alkanes are not suitable for asphalt emulsifiers; some quaternary ammonium salts with benzene rings or benzyl groups on branched chains have poor application effects; octadecyl trimethyl quaternary ammonium Salt has a good emulsifying effect

Embodiment 1

[0017] 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.

[0018] 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 preparation method of a novel cation asphalt emulsifier, which takes nicotinic acid and glycol as initial raw materials, an esterification reaction is carried out to obtain symmetrical gemini nicotinate, benzyl chloride on chloromethylated polystyrene (PVBC) resin is taken as an active center, and is grafted and quaternized to obtain water-insoluble gemini nicotinate pyridinium bactericide, and the novel water-insoluble gemini nicotinate pyridinium asphalt emulsifier is prepared, and thereby an optimum synthesis technology is given. The synthesized emulsifier is the slow-cracking asphalt emulsifier. The method can be widely used for a bonding layer, a fog sealing layer and solvent-free cold stirring and used for recovery / utilization of asphalt and bituminous pavement base stabilization.

Description

technical field [0001] The invention relates to the practical application of organic chemical synthesis and chemical products, and belongs to the field of organic synthesis and fine chemical industry. Background technique [0002] The so-called emulsified asphalt is to heat the viscous asphalt to a flow state, disperse it into tiny droplets by mechanical action, and then stably disperse it in an aqueous solution with an emulsifier-stabilizer to form an oil-in-water (O / W) type. The asphalt emulsion is a uniform and stable dispersion system with a tea-brown color and high fluidity. In emulsified asphalt, asphalt accounts for about 55% to 70% of the total mass, water accounts for 30% to 50%, and the content of emulsifier is only a few per thousand, but it plays a vital role in whether the asphalt can be uniformly and stably dispersed in water. role. Emulsified asphalt has been widely used in road engineering, building waterproofing, metal surface anticorrosion, desert sand fi...
