Solid waste-based backfill material and preparation method thereof
According to the solid waste-based backfill material and the preparation method thereof provided by the invention, in the method, glyceryl blind eel secretion is adopted to wrap coal cinder and other wastes with a specific proportion and smaller particle size, so that a relatively round composite continuous grading aggregate system is formed, the porosity of a later filler is reduced, the particle stacking density is increased, and the dense strength of the solid waste-based backfill material is improved. Silica hydrochloric acid cement powder and pure water in a specific ratio are matched with glyceryl blind eel secretion fixed on the surfaces of coal cinder particles and the like, and a composite gel particle structure of aggregate particles, biological protein gel and cement gel is formed from inside to outside. The structure can keep moisture, prevent a backfill material system from being solidified in advance, enhance the cohesiveness and compression resistance of the backfill material, enable the surface of the backfill material to be smoother and rounder, and reduce damage of hard protrusions to surrounding materials such as an extruded sheet and the like. The environment-friendly glyceryl blind eel secretion and diatomite ceramic particles are used, secondary pollution can be avoided while solid waste is treated, and the current environment-friendly requirement is met.
本发明提供一种固废基回填料及制备方法，该方法中采用甘油基盲鳗分泌液包裹特定比例的、较小粒径的煤渣等废弃物，形成较为圆润的复合连续级配的骨料体系，减少后期填料的孔隙率，增大颗粒堆积密度，提高固废基回填料的密实强度。特定配比的硅盐酸水泥粉和纯水配合固定在煤渣颗粒等表面的甘油基盲鳗分泌液，由内而外形成骨料颗粒、生物蛋白凝胶和水泥凝胶的复合式凝胶颗粒结构。该结构能保持水分，避免回填料体系提前凝固，还增强回填料的粘聚性和抗压能力，使回填料的表面更加平整圆润，减少硬质突起对挤塑板等周围材质的损伤。本申请使用环境友好的甘油基盲鳗分泌液和硅藻土陶瓷颗粒，在处理固体废弃物的同时能避免二次污染，符合当前环保需求。
