Multifunctional asphalt modifier and preparation method thereof
The invention belongs to the technical field of asphalt pavement materials, and particularly relates to a multifunctional asphalt modifier, which is prepared from the following raw materials in parts by mass: 12 to 25 parts of surface modified aerogel powder, 40 to 60 parts of surface modified tourmaline powder, 10 to 16 parts of multi-base porous polymer powder and 20 to 35 parts of zeolite powder. The surface-modified tourmaline powder can reduce the mixing temperature, reduce pollutants and play a role in cooling and deodorizing; the zeolite powder has an adsorption effect and can adsorb pollutants such as small solid particles in the asphalt smoke, so that a smoke suppression effect is achieved; the surface-modified aerogel powder and the multi-base porous polymer have a synergistic effect, so that a heat insulation effect is achieved. The invention also discloses a preparation method, so that powder with different particle sizes and properties is mixed more uniformly, and a better synergistic effect is achieved; the dispersibility of the tourmaline and the SiO2 aerogel in the asphalt can be better improved, and the compatibility of the tourmaline and the SiO2 aerogel with the asphalt is improved. The process is simple and easy to operate and popularize.
本发明属于沥青路面材料技术领域，具体涉及一种多功能沥青改性剂，以质量份数计，包括以下原料：表面改性的气凝胶粉体12～25份、表面改性的电气石粉40～60份、多基多孔聚合物粉10～16份、沸石粉20～35份。表面改性的电气石粉可以降低拌合温度，还原污染物，起到降温净味作用；沸石粉具有吸附作用，可以吸附沥青烟中的固体小颗粒等污染物，起到抑烟效果；表面改性的气凝胶粉体与多基多孔聚合物协同作用，起到隔热的作用。还公开了其制备方法，使不同粒径与性质的粉体混合更加均匀，起到更好的协同作用；可以使电气石及SiO2气凝胶在沥青中更好地分散性提高，提高其与沥青的相容性。该工艺简单，易操作，易推广。
