Abstract

The invention belongs to the technical field of building materials, and particularly relates to a light partition board prepared from coal slurry and a preparation method of the light partition board.The light partition board comprises the following components: water, a cement additive, a waterproof agent, short fibers, active slag powder, calcium oxide, coal slurry and Portland cement. A prepared partition wall has the properties of light weight, high strength, environmental protection performance, heat insulation, sound insulation, water resistance, stable size, good impact resistance, highcarbonization resistance, A-grade fire prevention performance and the like. Water-containing coal slime produced in a coal washing and dressing plant is adopted, and water contained in the coal slimeis used as mixing water for preparing slurry of light partition board products, so the problems of high energy consumption, high pollution and cost increase caused by drying in a drying forming process in the prior art are solved; a new path for coal slime utilization is developed for coal washing enterprises, and the problems of land resource waste, hidden environmental pollution danger and thelike caused by coal slime accumulation are further eliminated.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a lightweight partition board made from coal slurry and a preparation method thereof. Background technique [0002] Partition wall board refers to the wall prefabricated slab used for the internal partition wall of the building. The partition wall board includes glass fiber reinforced cement slab, glass fiber reinforced gypsum hollow slab, steel wire (steel mesh) reinforced cement slab, light concrete Slats, composite sandwich lightweight slats, etc. [0003] The full name of the partition board is a lightweight strip for building partition walls, which is used as the main material for non-load-bearing inner partition walls in general industrial buildings, residential buildings, and public construction projects. [0004] Among the existing patents, CN201910820584.X discloses a self-insulating lightweight aggregate partition wall panel and its preparation m...
