Zwitter-ion and nonionic composite asphalt warm-mixing agent and preparation method thereof
The invention discloses a zwitter-ion and nonionic composite asphalt warm-mixing agent and a preparation method thereof. The zwitter-ion and nonionic composite asphalt warm-mixing agent comprises in percentage by weight: 0.1-20% of zwitter-ion components, 0.1-20% of macromolecule nonionic components, 0.1-15% of low-molecular-weight nonionic components, 0.1-3% of acid catalysts and 42-99.6% of water. The preparation method comprises the following steps: the water is added into a container in the proportion, the temperature is controlled to range from 40 DEG C to 60 DEG C, the macromolecule nonionic components are added, a mixture is stirred for 0.5-2 hours at a constant temperature and then heated to 60-80 DEG C, the low-molecular-weight nonionic components and the zwitter-ion components are added in the proportion and are respectively stirred for 0.5-1 hours, the acid catalysts are added so that a pH (potential of hydrogen) can be adjusted to be 5-7, and the composite asphalt warm-mixing agent is obtained. The zwitter-ion and nonionic composite asphalt warm-mixing agent can effectively reduce high-temperature viscosity of the asphalt, improves the anti-peeling performance of the asphalt and stone and has the advantages of good compounding performance, stable performance, easiness of collection of the raw materials, low production cost, simple and convenient preparation method, wide application range and the like.
