[0018] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.
[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0020] like Figures 1 to 3 As shown, in an embodiment of the utility model: a lightweight, high-strength, water-resistant gypsum board comprises a gypsum layer 1, the gypsum layer 1 is provided with several layers superimposed on each other, a fiber mesh 101 is provided inside the gypsum layer 1, a cardboard 2 is provided on the outer layer of the gypsum layer 1, a waterproof layer 3 is coated on the outer side of the cardboard 2, a reinforcing rod 4 is provided on the inner side of the cardboard 2, and a support frame 401 is fixedly connected between two groups of reinforcing rods 4.
[0021] Three groups of fiber meshes 101 are provided, and each group of fiber meshes 101 is respectively provided between two adjacent groups of gypsum layers 1. The internal structure of the gypsum layer 1 is reinforced by multiple layers of fiber meshes 101, so that the internal structure of the gypsum layer 1 is enhanced and not easily deformed or broken.
[0022] The fiber mesh 101 is configured as a diamond mesh structure, and the diamond mesh structure can improve the fastening strength between the fiber mesh 101 and the gypsum layer 1 .
[0023] The reinforcing rod 4 and the supporting frame 401 are made of glass fiber rod material. The glass fiber rod has a hard structure and is light in weight. When reinforcing the external structure of the gypsum layer 1, it makes the overall strength of the gypsum board high and the weight light.
[0024] The support frame 401 is disposed inside the gypsum layer 1 and the fiber mesh 101 , and the surface of the support frame 401 is fixedly connected to the fiber mesh 101 and the inside of the gypsum layer 1 .
[0025] A waterproofing agent is added to the inside of the gypsum layer 1, so that the gypsum inside the gypsum layer 1 has a certain waterproof ability and enhances the waterproof durability.
[0026] In summary, the working principle of the present invention is as follows: by stacking an array of gypsum layers 1 and an array of fiber meshes 101 on each other, the internal structural strength of the gypsum board can be enhanced, so that the gypsum board is not easily deformed. At the same time, a reinforcement rod 4 is provided on the outside of the gypsum layer 1, which can enhance the external structural strength of the gypsum board, so that the gypsum board has good pressure resistance and is not easily damaged or broken. Secondly, after a waterproofing agent is added to the inside of the gypsum layer 1, the inside of the gypsum layer 1 has a certain waterproof effect. At the same time, a waterproof layer 3 is applied to the outer surface of the cardboard 2. The waterproof layer 3 can prevent external water from entering the inside of the gypsum layer 1, thereby further enhancing the waterproofing, so that the gypsum board has the effects of structural enhancement and good water resistance.
