Problems solved by technology

However, it is inevitable that some water will remain between the asphalt and aggregate interface during the production process, making the asphalt mixture potentially water-damaged
Moreover, if the amount of water added is too large, a large amount of water vapor will be generated or bumping will occur. If the amount of water is too small, the foaming effect will be poor.
[0007] At present, there are many warm-mix asphalt additive products, such as CN101899218A, CN101831187A, CN102795801A, etc. Although these warm-mix asphalt additive products can basically achieve the cooling effect and can successfully produce warm-mix asphalt mixture, it is inevitable that there will be production Defects such as complicated process, high energy consumption, and reduced performance of asphalt mixture

Abstract

The invention discloses an anionic liquid-crystal-form asphalt warm-mixing agent and a preparation method therefor. The asphalt warm-mixing agent contains the raw materials in parts by weight: 5.5-40.6 parts of sulfosuccinate, 0.1-20 parts of fatty alcohol and 39.4-94.4 parts of water. The preparation method comprises the following steps: (1) uniformly mixing the water and the sulfosuccinate in a vessel according to a proportioning ratio; and (2) adding the fatty alcohol into a material obtained in the step (1), carrying out uniform mixing, and carrying out standing for a period of time, thereby obtaining the anionic liquid-crystal-form asphalt warm-mixing agent. The asphalt warm-mixing agent disclosed by the invention can be used for effectively lowering the high-temperature viscosity of asphalt and has the advantages that the performance is stable, the raw materials are easily acquired, the preparation method is simple and convenient, the range of application is wide, and the like.

Description

technical field [0001] The invention relates to an asphalt warm mix agent and a preparation method thereof, in particular to an anionic liquid crystal type asphalt warm mix agent and a preparation method thereof. Background technique [0002] Since asphalt was used in roads, the mature asphalt mixture is mainly hot mix asphalt mixture. However, hot mix asphalt mixture has defects such as high mixing temperature and paving temperature, high emission of harmful gases, and easy aging of asphalt mixture. , resulting in many ecological and environmental problems. [0003] Warm mix asphalt mixture is a new material that is environmentally friendly and energy-saving. It has the same or even better road performance as the corresponding hot mix asphalt mixture, but it can be mixed and paved at a lower temperature, which greatly reduces the The energy consumption and soot emission in the production process have significantly improved the economic benefits and ecological value.
