Anionic-nonionic compound asphalt warm mix agent and preparation method thereof
The invention discloses an anionic-nonionic compound asphalt warm mix agent and a preparation method thereof. The anionic-nonionic compound asphalt warm mix agent comprises the following components in percentage by weight: 0.1-10 % of a high-molecular anionic component, 0.1-20 % of a low-molecular anionic component, 0.1-20 % of a nonionic component and 50-99.7 % of water. The preparation method for the warm mix agent comprises the following steps: adding water into a container according to the ratio, adding the high-molecular anionic component, stirring at a constant temperature for 0.5-1 hour, controlling the temperature to be 40-60 DEG C, adding the low-molecular anionic component and the nonionic component according to the ratio, and continuously stirring for 0.5-1 hour to obtain the product. The asphalt warm mix agent can effectively reduce the viscosity of asphalt at a high temperature, and has the advantages of being good in compounding characteristic, stable in property, easy to collect raw materials, low in manufacturing cost, simple and convenient in preparation method, wide in application range and the like.
