Problems solved by technology

[0003] However, the existing gypsum board has the following problems: its waterproof and moisture-proof effect is poor. When the gypsum board absorbs water and gets wet, its hardness decreases, and in severe cases, it will even delaminate; its sound insulation effect is poor; There is an easy-peelable protective film attached to the surface, but the existing easy-peelable protective film cannot bear the pulling force during peeling, and breakage occurs during peeling, resulting in difficulty in peeling off

Embodiment

[0040] Such as Figure 1-3 As shown, a colorful gypsum decorative board includes a gypsum board 50, the two sides of the gypsum board 50 are respectively provided with a protective layer 80 and a polyvinyl chloride film 20, and the polyvinyl chloride film 20 and the gypsum board 50 are provided with There is an adhesive layer; the protective layer 80 is a paper protective layer, a plastic protective layer or a steel mesh. The water and moisture resistance of the gypsum board 50 is increased by setting the polyvinyl chloride film 20 .

[0041] In another embodiment, the polyvinyl chloride film 20 and the gypsum board 50 are sequentially provided with a first sound-insulating layer 30 and a first waterproof layer 40, the polyvinyl chloride film 20, the first sound-insulating layer 30, the first waterproof layer An adhesive glue layer is provided between the layer 40 and the gypsum board 50 .

[0042] The first waterproof layer 40 is set between the polyvinyl chloride film 20 a...

Abstract

The invention discloses a colorful gypsum decorative sheet and a preparing method thereof. The colorful gypsum decorative sheet comprises a gypsum plate, the two side faces of the gypsum plate are provided with a protective layer and a polyvinyl chloride film, and a bonding glue layer is arranged between the polyvinyl chloride film and the gypsum plate; and the protective layer is a paper protective layer, a plastic protective layer or a steel mesh. The polyvinyl chloride film is arranged, and therefore the waterproof and dampproof performance of the gypsum plate is improved. According to thecolorful gypsum decorative sheet prepared through the preparing method, the waterproof and dampproof effect is good, and the sound insulation performance is good.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a colorful gypsum decorative board and a preparation method thereof. Background technique [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 and convenient processing. It is one of the new lightweight panels 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 for interior partition walls, wall cladding panels (replacing plastering layers on walls), ceilings, ground floor panels and various decorative panels. Wait. [0003] However, the existing gypsum board has the following problems: its waterproof and moisture-proof effect is poor. When the gypsum board absorbs water and gets wet, its hardness decreases, and in severe ca...
