Modifier for improving stability of steel slag aggregate and preparation method thereof
The invention belongs to the field of road building materials, and discloses a modifier for improving stability of steel slag aggregate and a preparation method thereof, the modifier comprises the following preparation raw materials: ethanol, resin, a silane coupling agent, a curing agent, a curing accelerator, a flexibilizer, a stabilizer, boron nitride, and 2-hydroxy-4-methoxybenzophenone. The modifier is an oil-soluble interface modifier, a layer of micron-level film can be plated on the surface of the steel slag and is compact and uniform, and the prepared modified steel slag is low in water absorption rate and good in volume stability; the obtained modified steel slag is mixed with asphalt, the effect of improving the adhesion performance of the aggregate and the asphalt is achieved through physical and chemical changes, the adhesion level can reach level 5, and the pavement performance of the obtained modified steel slag asphalt mixture is superior to that of an asphalt mixture with stone as the aggregate; and the preparation method is simple and easy to operate and implement.
本发明属于道路建筑材料领域，公开了一种提高钢渣集料稳定性的改性剂及其制备方法，该改性剂包括以下制备原料：乙醇、树脂、硅烷偶联剂、固化剂、固化促进剂、增韧剂、稳定剂、氮化硼、2‑羟基‑4‑甲氧基二苯甲酮。该改性剂为油溶型界面改性剂，可在钢渣表面镀上一层微米级别的薄膜，致密而均匀，制得的改性钢渣吸水率较低，体积稳定性好；所得的改性钢渣再与沥青混合经过物理化学变化达到提高集料与沥青粘附性能的效果，粘附等级能到5级，且使所得的改性钢渣沥青混合料的路用性能优于石料做集料的沥青混合料；其制备方法简单，易于操作实施。
