Abstract

The invention belongs to the field of building materials, in particular to a cement ceiling board and a preparation method thereof. The cement ceiling board is composed of polypropylene fiber mesh cloth and cement boards, wherein the polypropylene fiber mesh cloth is laid between the cement boards to form a cement ceiling board composed of upper, middle and lower layers. The present invention lays the polypropylene fiber mesh cloth in the middle of the cement board when preparing the cement ceiling board. When the thickness of the prepared cement ceiling board is relatively thin, the cement board can be provided with good flexural strength, and the cement board can be avoided during processing. The board is easily broken, so cement can be used to make ceiling boards, and the prepared ceiling boards are light in weight and easy to process and install.

Description

technical field [0001] The invention belongs to the field of building materials, and particularly relates to a cement ceiling board and a preparation method thereof. Background technique [0002] Ceiling panels are widely used in various interior decorations. The existing ceiling panels can be mainly divided into three categories: decorative gypsum ceiling panels, metal composite ceiling panels and organic polymer ceiling panels. [0003] Decorative gypsum board ceiling board is made of gypsum as the main raw material, adding fibers, adhesives, modifiers, kneading, pressing, and drying. performance. For example, Patent Document 201510227888.7 discloses a glass fiber composite reinforced gypsum ceiling board and its ceiling structure, including connecting rods, ceiling gypsum boards, and positioning frames, wherein the ceiling gypsum board is a rectangular groove structure, and the upper surface edge is provided with connection positioning The groove wall, the lower surface...
