Abstract

The invention belongs to the technical field of building material preparation, and particularly relates to a preparation method of a light partition board. According to the invention, cement, calcinedgypsum, caustic-burned magnesia powder, fly ash and quick lime are mixed and ball-milled to obtain dry-mixed mortar, the dry-mixed mortar, modified diatomite, water and a foaming agent solution are mixed to prepare slurry, the slurry is poured into a mold to obtain the light partition board. The light partition board prepared through the method is good in compressive strength, low in heat conductivity coefficient, good in heat preservation performance, good in sound insulation effect and wide in application prospect.

Description

technical field [0001] The invention belongs to the technical field of building material preparation, and in particular relates to a preparation method of a lightweight partition board. Background technique [0002] Building partition wall board products are a kind of product in the wall material industry. Because the board size is neat, the integrity is good, it is easy to form, it is convenient for mechanized production and assembly installation, and it realizes industrialization of production, product standardization and construction assembly, and can save Raw materials, thinning the thickness of the wall, reducing the weight of the wall, effectively improving the comprehensive economic benefits of the building. Today, building partition board products have gradually become the main wall material for the enclosure and partition of the structure. The existing representative building partition boards include glass fiber reinforced cement lightweight porous partition wall st...
