Problems solved by technology

[0009] Further, at present, high-end clubs or home decoration all use wood boards as decoration materials to highlight the high-end and atmospheric decoration effect, but ordinary wood boards are easy to absorb moisture and mold, which will affect the home decoration effect
In addition, wood boards are easy to burn. Once a fire breaks out, the consequences will be disastrous, which will bring great safety hazards to people's lives.
Therefore people tend to use gypsum board with fireproof function, but the surface texture of existing gypsum board for interior wall decoration is single, which cannot meet people's needs well, especially the log wood grain texture, because of its advantages such as noble decorative effect , has always been favored by people, so if the natural texture of

Example Embodiment

[0119] Example 1:

[0120] 1) Preparation of gypsum substrate layer 1 slurry: mix 72kg α-high-strength desulfurized gypsum powder, 3kg bisphenol A epoxy resin, 0.1kg citric acid, 0.5kg acrylic emulsion, 24.4kg water, and mix well to obtain gypsum slurry .

[0121] 2) Formation of gypsum base material layer 1: Coat a layer of release agent inside the mold, and then spray the above-mentioned gypsum slurry. After the gypsum slurry is initially set, put the three-dimensional reinforced fiber fabric 2 into it, then slowly pour the remaining gypsum slurry, gently shake it until the surface is smooth and clean, and then stand for a while. The three-dimensional reinforced fiber fabric 2 is woven from glass fiber The height of the middle layer 22 is 12mm.

[0122] 3) Curing of the gypsum base material layer 1: The formed gypsum base material layer is cured at room temperature for 4 hours, and then demolded; the demolded product is placed in a curing room for curing for 1 day, and then the g...

Abstract

The invention discloses a reinforced plasterboard and a preparation method thereof. The plasterboard comprises a plaster base material layer, and a three-dimensional reinforced fiber fabric embedded into the plaster base material layer, wherein the three-dimensional reinforced fiber fabric consists of an upper layer, an intermediate layer and a lower layer; the upper layer and the lower layer are meshed plate fiber layers; the intermediate layer refers to an 8-shaped fiber framework; and the upper and lower ends of the 8-shaped fiber framework are respectively connected with the plate fiber layers on the upper and lower layers. The three-dimensional reinforced fiber fabric serves as a product reinforcement material, and three-dimensional directional enhancement of glass fibers is structurally realized, so that the plate structure is uniform in stress. Compared with gridding cloth layout or short fiber injection and pouring and other processes, the method has the advantages that the breaking strength and compressive strength are greatly improved, and a mechanical guarantee is provided for production of large-specification/size plates. The preparation method disclosed by the invention is simple in process, and the obtained product is good in performance.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a reinforced gypsum board and a preparation method thereof. Background technique [0002] In recent years, gypsum board has been favored by users for its advantages of light weight, non-combustibility, and "breathing" function. It is widely used in interior wall decoration of houses. It is easy to break, and the wall is easy to crack after installation, which brings inconvenience to the construction; it also causes huge losses. [0003] Although fibers are added to reinforce the gypsum board in the prior art, the mechanical strength of the gypsum board still cannot meet the requirements of many application occasions due to the problem of unreasonable fiber layout. [0004] There are three types of fibers in the prior art: short fibers, fiber mats and grid cloths. The method of mixing short fibers into gypsum ingredients to achieve reinforcement, due to the limitation of the ex...
