Embodiment 1

[0018] Example 1: Take 5g of emulsifier, add 200ml of water, heat to 60-70°C, dissolve into a solution, then weigh 300g of ordinary No. 100 asphalt, heat to 120°C, start the colloid mill, and add the hot water solution of emulsifier to the colloid mill Slowly pour the hot asphalt into the machine for emulsification, stop the machine after 1 minute, and put the emulsion into a mineral water bottle for analysis.

[0019] Weigh 100g of stone, take a certain amount of water and additives, add it to an iron bowl, mix evenly, then weigh a certain amount of emulsified asphalt, pour it into an iron bowl, stir quickly and fully, and start timing, and the record can be mixed time and molding time.

[0020] Emulsification conditions: No. 100 road petroleum asphalt, pH=2~3, emulsifier dosage is 1%~2%.

[0021] Emulsification effect: complete emulsification, good effect.

[0022] Storage stability: long-term storage without precipitation and demulsification phenomenon, good stability.

Embodiment 2

[0028] Example 2: 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 300AH-90 asphalt and heat it to 120°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

Cationic asphalt emulsifier lignin-amine is prepared from waste water as a solvent and lignin, triethylene tetramine and formaldehyde as raw materials by Mannich reaction. The best preparation condition for the preparation of the lignin lignin-amine is as follows: the reaction temperature is 85 DEG C, the reaction time is 5h, and the ratio of (formaldehyde): n (triethylene tetramine) = 3.0. By FTIR characterization, the structures of lignin-amine prepared by use of the waste water as the solvent and deionized water as the solvent are same, the wastewater is comprehensively utilized. The performance index of the emulsified asphalt prepared by use of the prepared lignin-amine as an emulsifier can reach index of the JTG E20-20 of the highway engineering asphalt and asphalt mixture test procedures.

Description

technical field [0001] The invention relates to the synthesis of organic chemical products and the effect of the products on environmental protection, belonging to the fields of fine chemical industry and environmental engineering. Background technique [0002] At present, the domestic preparation of cyclohexanone mainly adopts cyclohexane air oxidation method. The process uses benzene and hydrogen as the main raw materials to produce cyclohexanone through steps such as hydrogenation, cyclohexane oxidation, peroxide decomposition and dehydrogenation. Cyclohexanone production wastewater has the characteristics of large water volume, high pollutant concentration and complex composition. At present, most domestic enterprises use steam stripping method, micro-electrolysis-coagulation method and extraction method to treat cyclohexanone production wastewater, but all of them have the disadvantage of high energy consumption. [0003] Emulsified asphalt is widely used in highway e...
