Abstract

The invention discloses a glass fiber felt gypsum board, which comprises a gypsum board core and a glass fiber felt protective surface, and is characterized in that the gypsum board core comprises gypsum, a waterproof agent, a mildew preventive, chopped glass fibers, a reinforcing agent, a water reducing agent, modified starch, a powder additive, a foaming agent and water. The glass fiber felt gypsum board has good water resistance, fire resistance, mildew resistance, breaking load and weather resistance, and can be applied to an outer wall or a temporary outer wall. The invention further discloses a preparation method of the glass fiber felt gypsum board. The preparation method comprises the following steps: uniformly stirring the chopped glass fibers, gypsum, the reinforcing agent, the powder additive, the water reducing agent and the modified starch to obtain solid powder; adding the waterproof agent, the mildew preventive and the foaming agent into water, and stirring until foamingto obtain an aqueous solution; adding the solid powder into the aqueous solution, uniformly stirring to obtain gypsum slurry, and forming, solidifying, conveying, cutting and drying the gypsum slurryon a glass fiber felt to obtain the glass fiber felt gypsum board.

Description

technical field [0001] The application relates to the field of building materials, in particular to a glass fiber felt gypsum board and a preparation method thereof. Background technique [0002] As people pay more attention to environmental protection and health, the demand for functional gypsum boards is increasing. Due to the characteristic factors of the gypsum core material and the protective paper, the traditional gypsum board has poor waterproof, fireproof, mildew resistance and mechanical properties. Used in building exterior walls. The main feature of glass fiber felt gypsum board is that glass fiber felt is used instead of protective paper. Because glass fiber felt has excellent fireproof and waterproof performance, glass fiber felt gypsum board has a certain degree of waterproof and fireproof performance compared with paper-faced gypsum board. improvement. [0003] In the existing glass fiber mat gypsum board, the performance of the gypsum core material and the...
