Abstract

The invention discloses formaldehyde-removing plaster gypsum and a preparation method thereof. The formaldehyde-removing plaster gypsum is prepared from a phosphogypsum component, a lightweight aggregate component, a PH regulator component, a water-retaining agent component, a modifier component, a retarder component and a photocatalysis component. The formaldehyde-removing plaster gypsum providedby the invention has all properties such as fire resistance, environmental protection, heat insulation, sound absorption and shock resistance of traditional plaster gypsum, and further has the function of formaldehyde removing.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a formaldehyde-removing plastering gypsum and a preparation method thereof. Background technique [0002] In recent years, with the improvement of people's living standards, people's requirements for interior decoration standards have become higher and higher, and home decoration has become increasingly modernized. However, the problem of indoor formaldehyde pollution caused by materials and decoration has followed. Formaldehyde is a color, gas with a strong pungent smell, it is very volatile at room temperature, and the volatilization speed is accelerated as the temperature rises. At present, the common indoor formaldehyde removal method is to ventilate for a long time or use an air purification device to remove it, but the efficiency is low and the cost is high. [0003] The current plastering materials include cement-based plastering materials, desulfurized gypsum plastering...
