Description

Technical Field

[0001] The utility model relates to the technical field of paper-faced gypsum boards, in particular to a paper-faced gypsum board with antibacterial and mildew-proof functions. Background Art

[0002] Gypsum board is a material made of building gypsum as the main raw material. It is a building material with light weight, high strength, thin thickness, easy processing, good sound insulation, heat insulation and fire resistance, and is one of the new lightweight boards that are currently being developed. Gypsum board has been widely used in various buildings such as residential buildings, office buildings, shops, hotels and industrial plants, such as interior partitions, wall covering panels (instead of wall plastering), ceilings, sound-absorbing panels, ground base panels and various decorative panels. It is not suitable to be installed in bathrooms or kitchens for indoor use. Paper-faced gypsum board is a type of gypsum board. It is made of building gypsum as the main raw material, with appropriate additives and fibers as the board core, and special board paper as the surface. Paper-faced gypsum board has the characteristics of light weight, sound insulation, heat insulation, strong processing performance and simple construction method.

[0003] However, the relevant paper-faced gypsum board still has some shortcomings when used. Although it has the characteristics of light weight, sound insulation, heat insulation, strong processing performance and simple construction method, its antibacterial effect is not ideal, and the adsorption effect is poor, which makes the mildew-proof and purification effects need to be improved. Therefore, we propose a paper-faced gypsum board with antibacterial and mildew-proof functions to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the above-mentioned shortcomings and proposes a gypsum board with antibacterial and mildew-proof functions.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] Preferably, a fiber layer is fixedly connected between the antibacterial layer and the gypsum base layer.

[0008] Preferably, the two anti-mildew layers are fixedly connected to anti-cracking cloths on the sides away from each other, and the two anti-cracking cloths are respectively fixedly connected to the top of the lower paper surface layer and the bottom of the upper paper surface layer.

[0009] Preferably, the antibacterial layer comprises a chitosan antibacterial layer, and a quaternary phosphate antibacterial layer is fixedly connected to the bottom of the chitosan antibacterial layer.

[0011] Preferably, the anti-mildew layer comprises an adsorption layer fixedly connected to the outside of the antibacterial layer, and a breathable layer is fixedly connected to the bottom of the adsorption layer.

[0012] Preferably, the adsorption layer is made of activated carbon material.

[0013] In the utility model, the gypsum board with antibacterial and mildew-proof functions can protect the upper and lower sides of the gypsum board layer through the upper paper surface layer and the lower paper surface layer, and can enhance the overall strength of the gypsum board through the fiber layer, so that it is not easy to be damaged. The anti-cracking cloth is provided to achieve the effect of anti-cracking and anti-breaking. The double-layer antibacterial antibacterial layer composed of the chitosan antibacterial layer and the quaternary phosphate antibacterial layer solves the problem that the killing effect of fungi by the single antibacterial is not good, and the antibacterial use range and effect of the gypsum board are expanded. The chitosan antibacterial layer is made of chitosan material, and chitosan has strong adsorption and contains amino groups, which can adsorb and decompose indoor formaldehyde harmful substances, thereby giving the gypsum board the function of purifying the air, and can absorb moisture at the same time, achieving a certain mildew-proof effect.

[0014] In the utility model, the gypsum board with antibacterial and mildew-proof functions can further absorb moisture and harmful substances in the room through the adsorption layer made of activated carbon material in the mildew-proof layer, which can further improve the mildew-proof effect, and at the same time can further improve the air purification effect of the gypsum board. Through the air permeable layer, the gypsum board has better air permeability, which plays a role in ventilation, moisture-proof and mildew-proof effects.

[0015] The utility model has a reasonable structural design. Through the double-layer antibacterial layer of chitosan antibacterial layer and quaternary phosphate antibacterial layer, the problem of poor killing effect of fungi by a single antibacterial layer is solved. The chitosan antibacterial layer has strong adsorption and contains amino groups, which can adsorb and decompose indoor formaldehyde harmful substances, giving the paper-faced gypsum board the function of purifying the air. At the same time, it can absorb moisture and have a certain anti-mildew effect. Through the adsorption layer, it can further absorb moisture and indoor harmful substances, further improving the anti-mildew and purification effect. BRIEF DESCRIPTION OF THE DRAWINGS
