Embodiment 1

[0023] Example 1: Accurately weigh a certain amount of asphalt emulsifier, dissolve it in 100 mL of water, heat the emulsifier aqueous solution to 70° C., and adjust its pH to 1-2. Weigh 100g of asphalt and heat to 120°C. Preheat the colloid mill with hot water. After turning on the colloid mill, first add the hot water solution of emulsifier, and then slowly pour the hot asphalt into the colloid mill. After emulsifying for 1 minute, stop the machine, and then bottle the emulsified asphalt emulsion down to room temperature.

[0024] Weigh 100g of stone, take a certain amount of water and additives, add it to the iron bowl, mix well, then weigh a certain amount of emulsified asphalt, pour it into the iron bowl, stir quickly and fully, and start timing, record that it can be mixed Time and molding time.

[0025] According to T0655-1993 emulsified asphalt storage stability test, the emulsified asphalt was lowered to room temperature and bottled, and the storage stability was observed...

Abstract

The invention provides synthesis of a Gemini type cationic asphalt emulsifier--1,3-{N-[3-dodecyloxy polyoxyethylene ether(9)-2-hydroxy]propyl dimethyl}propane from aliphatic polyoxyethylene ether AEO-9, epichlorohydrin, dimethylamine and 1,3-dibromopropane. The Gemini type cationic asphalt emulsifier is used for preparing emulsified asphalt. The test results of the emulsified asphalt show that the prepared emulsified asphalt can be stably stored for 5 days when the usage amount of the emulsifier is 2.5% of the total amount of the emulsified asphalt. The Gemini type cationic asphalt emulsifier provided by the invention can be extensively applied to adhesive bonding layers, fog sealing layers and solvent-free cold mixing, and is used for recycling of asphalt and stabilization of a asphalt pavement base.

Description

Technical field [0001] The invention relates to the synthesis of organic chemical products and their practical application in the field of asphalt road pouring, and belongs to the field of fine chemicals and building materials. Background technique [0002] Emulsified asphalt is to heat cold asphalt to a fluid state, and then through the action of mechanical force, the asphalt can be dispersed in a fine particle state in an aqueous solution containing a certain amount of emulsifier to form an oil-in-water (0W / ) asphalt Emulsion, this asphalt emulsion is liquid at room temperature and has high fluidity. Emulsified asphalt is a road asphalt that is usually used at high temperature. After mechanical stirring and chemically stable methods (emulsification), it diffuses into water and liquefies to become very viscous at room temperature. A road construction material with low flowability. It can be used at room temperature and can be used with cold and wet stones. Emulsified asphalt i...
