Abstract
The invention discloses anion-cation compound emulsified asphalt, which is prepared from the following ingredients (by weight): 55-70 parts of asphalt, 2-4 parts of an emulsifier, 0.5-1 part of a stabilizing agent and 30-45 parts of water. The emulsifier contains an anionic emulsifier, a cationic emulsifier and a non-ionic emulsifier at the ratio of 1: 1: 2. The compound emulsified asphalt is prepared by the following method: heating asphalt to a molten state, dissolving the emulsifier and the stabilizing agent in water of 50-90 DEG C to prepare a soap solution, preparing an emulsified soap solution by colloid mill emulsification equipment, slowly adding the emulsified soap solution into the molten asphalt, stirring at high speed, continuously stirring at high speed for 30 min-45 min when the emulsified soap solution is all added into the molten asphalt, and cooling to room temperature to obtain the anion-cation compound emulsified asphalt. Due to anion-cation charge balance, solution polarity is reduced. Accordingly, storage stability of the emulsified asphalt is greatly raised, and storage time of the emulsified asphalt can be prolonged to three months.
Description
Technical field
The present invention relates to asphalt production technical field, be specially a kind of zwitterion compound emulsion Colophonium.
Background technology
Emulsified asphalt is to be configured to soap lye with emulsifying agent, then Colophonium is heated to certain temperature, utilize colloid mill emulsifying device by miscible to soap lye and Colophonium to together with and prepare come, emulsifying agent in the market is varied, but can unite according to its electrically charged type and be divided into cationic emulsifier, anion emulsifier and nonionic emulsifier, the emulsified asphalt utilizing cationic emulsifier to be fabricated to just is cationic emulsified bitumen, and the emulsified asphalt utilizing anion emulsifier to be fabricated to just is anionic emulsified bitumen.
Although emulsified asphalt range of application is increasingly wider, but due to its existence and stability shortcoming poor, the most easily-storied, it is impossible to long-time storage, so since the most directly limit its scope of application；In order to solve this problem, many research units increase its stability by modes such as interpolation stabilizer, raising equipment emulsifying capacity, emulsifying agent compound, and it is cation-cation, anion-anion, cation-nonionic and Anionic-nonionic mostly that the emulsified asphalt of present stage compounds mode；Owing to cation and anion are with opposite charges in traditional sense, both meet and emulsified asphalt breakdown of emulsion thus will can be made to use in conjunction with electric discharge so that emulsifying agent loses activity, so nearly no anionic-cationic compounds.
