Pavement material based on mine solid waste and preparation method thereof
The invention provides a pavement material based on mine solid waste and a preparation method thereof, and belongs to the field of slag, the preparation method comprises the following steps: crushing and grinding the mine solid waste to obtain mine solid waste particles; mixing the mine solid waste particles with a chemical stabilizer to obtain first slurry, and mixing, granulating and sintering the first slurry and silica sand to obtain surface-vitrified cyclosiliceous stable ore ceramic particles; the modified bio-based polylactic acid, silica gel particles, polystyrene porous microspheres and polyacrylate are mixed and stirred, then diisopropoxy dititanium, rosin and epoxidized vegetable oil are added and stirred, and a bio-based polymer binder is obtained after a reaction; the prepared cyclic silicon stable ore ceramic particles are mixed with a bio-based polymer binder, cement and an additive through a wet method, second slurry is obtained, and the additive comprises a polycarboxylate superplasticizer, ethyl orthosilicate, trisodium phosphate and sodium dodecyl benzene sulfonate; and pressing the second slurry, and standing and maintaining to obtain the pavement material.
本发明提出了一种基于矿山固废的路面材料及其制备方法，属于矿渣领域，该制备方法包括：对矿山固废进行粉碎研磨，得到矿山固废颗粒；将矿山固废颗粒与化学稳定剂混合得到第一浆料，再将第一浆料与硅砂进行混合造粒和烧结，得到表面玻化的环硅稳矿陶瓷颗粒；将改性生物基聚乳酸、硅胶微粒、聚苯乙烯多孔微球和聚丙烯酸酯混合搅拌，再加入二异丙氧基双钛、松香、环氧化植物油搅拌，经反应后得到生物基聚合物粘结剂；再将制备得到的环硅稳矿陶瓷颗粒与生物基聚合物粘结剂、水泥和添加剂湿法混合，得到第二浆料，其中，添加剂包括聚羧酸酯超塑化剂、正硅酸乙酯、磷酸三钠和十二烷基苯磺酸钠；对第二浆料进行压制、静置养护，得到路面材料。
