Abstract

The invention discloses ceramsite sand prepared from waste ceramsite sand and used for 3D printing and a preparation method of the ceramsite sand. Waste ceramsite, aluminum-containing ore and silicon-containing waste are used as raw materials, sodium silicate in a solution can be used as a binder, adhesion among the materials is promoted through spraying to form regular spheres, and meanwhile, sodium hydroxide and sodium silicate are added. An alkaline environment is provided for the mixed material, glass bodies in the material are broken, silicon oxide, aluminum oxide and other components in the waste ceramsite sand are promoted to react, and the product strength is improved. The ceramsite sand with a perfect crystal structure is formed by pre-sintering at the temperature of 500 DEG C and then sintering at the high temperature of 1200 DEG C, and all the effective components react rapidly and crystallize, so that the mechanical property and the fire resistance of the product are improved. Recycling of various industrial and mining waste materials is achieved, the preparation process is simple, energy is saved, the environment is protected, and the cost of the ceramsite sand is reduced. The prepared ceramsite sand is uniform in structure, high in compactness, complete in form, excellent in mechanical property and high in high temperature resistance and corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of ceramsite sand preparation, in particular to ceramsite sand for 3D printing prepared from waste ceramsite sand and a preparation method thereof. Background technique [0002] 3D printing is one or several technologies that use bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing based on digital model files. During the 3D printing process, materials are easily broken and produce tiny particles such as dust, which can easily block the print head of the 3D printer, resulting in shortened print head life and increased equipment maintenance costs. The development and breakthrough of 3D printing materials is the key to the promotion and application of 3D printing technology. The foundation is also the fundamental guarantee for satisfying printing. [0003] Ceramsite sand is one or several kinds of refractory materials mainly composed of mullite phase. Due to its...
