Abstract

The invention provides an anti-mold and anti-bacterial paper-surface gypsum board and a preparation method thereof. The paper-surface gypsum board comprises a gypsum core and surface protective paperarranged on the surface of the gypsum core; the gypsum core is prepared from the following components: gypsum, a first mold inhibitor, a compound bactericide, a first waterproof agent and a gypsum reinforcer with the mass ratio being 100:(0.001 to 0.045):(0.005 to 0.2):(0.01 to 0.3):(0.01 to 1); and the surface protective paper is prepared from the following components: a second waterproof agent,a second mold inhibitor and a bactericide with the mass ratio being (0.05 to 0.5):(0.05 to 0.5):(0.1 to 1.5). The gypsum core of the anti-mold and anti-bacterial paper-surface gypsum board comprises the specific types of the mold inhibitor, the bactericide and the waterproof agent, the surface protective paper comprises the specified waterproof agent, bactericide and mold inhibitor, under the joint action, the paper-surface gypsum board has the good anti-mold effect, and the gypsum board has no odor and further has the good hardness and fracturing load in the existence of the gypsum reinforcer.

Description

technical field [0001] The invention belongs to the technical field of paper-faced gypsum boards, and in particular relates to a mildew-proof and antibacterial paper-faced gypsum board and a preparation method thereof. Background technique [0002] Paper-faced gypsum board is an interior decoration material produced mainly from gypsum and face-protecting paper. It is more and more popular in the construction market for its advantages such as light weight, fire prevention, environmental protection, and convenient construction. The raw materials used in plasterboard, such as facing paper, starch or other additives containing carbohydrates, provide conditions for the growth of mold. When the ambient humidity is high and the temperature is suitable, once enough water is absorbed, mold spores will proliferate in large numbers on the paper surface or core of the gypsum board, and mildew spots will appear, resulting in yellowing and blackening of the wall and ceiling due to mildew ...
