Cementing material for 3D printing and preparation method thereof
The invention discloses a cementing material for 3D printing and a preparation method thereof. The cementing material comprises fly ash, blast furnace slag, carbide slag, waste paper pulp, sodium silicate nonahydrate and a composite volume stabilizer, and the coagulation time is regulated and controlled by adjusting the mixing amount of the raw materials slag and sodium silicate nonahydrate. According to the method, three different grinding processes are mainly utilized, so that the quality of the cementing material is better, the coagulation time is shorter, and meanwhile, various propertiesof the cementing material are enhanced. The industrial problems of high cost, high energy consumption and the like are solved; all the selected materials are industrial solid wastes, so that the cementing material with high strength and adjustable coagulation time can be prepared, the problem of accumulation of environmental solid wastes is solved, the resource utilization of the solid wastes is realized, and the green development concept of China is met.
本发明公开了一种3D打印用胶凝材料及其制备方法，其材料包括粉煤灰、高炉矿渣、电石渣、废纸浆、九水硅酸钠和复合体积稳定剂，通过调节原材料矿渣和九水硅酸钠的掺入量来调控凝结时间。其方法主要利用三种不同的研磨工艺使得胶凝材料的品质更好，凝结时间更短，同时增强了胶凝材料的各项性能。解决了成本高，能耗大等工业化难题；选用的所有材料均为工业固体废弃物，可制备出强度高、凝结时间可调的胶凝材料，同时也解决了环境固废堆积问题，实现固体废弃物资源化利用，符合我国绿色发展理念。
