Abstract

The present invention discloses a wear-resistant gypsum board, which comprises the following raw materials by weight: 22-25 parts of sophora japonica charcoal with a particle size of 40-55 [mu]m, 50-55 parts of gypsum, 10-12 parts of ceramic powder, 5-8 parts of re-dispersible latex powder, and 2-4 parts of a foaming agent. The specific preparation method comprises sequentially performing the following steps. According to the present invention, the wear-resistant component is added in the formula, such that the strength and the hardness of the gypsum board are ensured, and the good wear resistance is provided.

Description

[0001] technical field [0002] The invention relates to the field of building materials used for interior decoration, in particular to wear-resistant gypsum boards. [0003] Background technique [0004] Gypsum board is widely used in building decoration materials because of its advantages of light weight, high strength, sound insulation and heat insulation, fire prevention, and easy processing. The wear resistance of gypsum board is general, and it is a direction of research in building materials, but its application scope still needs to be developed. [0005] SUMMARY OF THE INVENTION [0006] The purpose of the present invention is to provide a wear-resistant gypsum board with a wear-resistant formula added to the components, which ensures the strength and hardness of the gypsum board and has good wear resistance. [0007] The technical scheme of the present invention is as follows: [0008] Wear-resistant gypsum board is composed of the following parts by weight of...
