Abstract

The invention relates to the technical field of green building materials, in particular to a rapidly sintered lightweight silicon spar wallboard and a preparation method thereof. The wallboard is formed by mixing a solid material and water according to the weight ratio of 1: (0.1-0.2); the solid material is prepared from the following components in percentage by weight: 15 to 40 percent of aggregate, 55 to 75 percent of plastic material, 15 to 20 percent of fluxing agent and 3 to 15 percent of binder. Compared with the prior art, shale, coal gangue, fly ash, building residue soil, river and lake sludge, sludge and the like are used as main raw materials, production is more environmentally friendly, through adjustment of particle aggregate grading, compact and uniform accumulation is formed, internal structure gaps of a green body are reduced, the situation that various cracks appear in the rapid sintering and cooling process of a product is reduced, and the service life of the product is prolonged. The sintering period is reduced by more than 40%, the energy consumption of a unit product is reduced, the single-line production efficiency is improved, various physical and chemical indexes of the prepared product meet actual requirements, and the product apparent quality is excellent.

Description

technical field [0001] The invention relates to the technical field of green building materials, in particular to a rapidly sintered lightweight silica crystal wallboard and a preparation method thereof. Background technique [0002] Rapid sintering lightweight silica crystal wallboard is made of shale, coal gangue, fly ash, construction debris, river and lake silt, sludge, etc., through extrusion molding, drying and roasting, and contains holes prefabricated hollow slats. The product has high-quality properties such as light weight, high strength, thermal insulation, waterproof and moisture-proof, sound insulation and noise reduction, fire resistance and durability, freeze-thaw resistance, and easy cutting and processing. Under the background of prefabricated buildings, the products can be widely used in the construction of prefabricated wall projects , is a new type of environmentally friendly green high-end building materials. [0003] The fastest sintering cycle of the...
