Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to Chinese Patent Application No. 202411572786.4, filed on Nov. 6, 2024, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD The present application relates to the field of building panels, and in particular to a reinforced magnesium substrate and a composite board with the reinforced magnesium substrate. BACKGROUND In the field of building panels, boards laid on the ground or walls typically have the characteristics such as waterproofness, moisture resistance, low cost, and resistance to deformation, etc. In this regard, laminated flooring with fiberboard or granular board, or hard materials such as tiles and stone are mostly used in the market. Depending on the different needs of users, wooden boards, plastic boards, and hard boards are chosen to be laid on the floor or wall. When users use hard materials such as tiles and stone, although the materials themselves have the characteristics of beautifying objects, being easy to wipe and clean, and not being eroded by dust and dirt, due to their high hardness and poor toughness, they can withstand less external deformation. If tiles and stone are subjected to external stress, they will crack or break, therefore, when installing tiles and stone on walls or the floors, manual laying and bonding with adhesives, cement, etc. are usually used. Moreover, there is no additional structure for mutual fixation on the body of tiles and stone after or during cutting. Some users use common glass magnesium flat panels to replace tiles and stone, glass magnesium flat panels, also known as fireproof composite panels or magnesium oxide panels, are stable performance magnesium based cementitious materials made from a ternary system of magnesium oxide, magnesium chloride, and water, configured and modified with additives. Although glass magnesium flat panels are good in fireproofing, strength, waterproofness and moisture resistance, they will undergo significant deformation when exposed to dark and humid environments for a long time, which will affect the stability of decoration; In addition, the maintenance period of glass magnesium flat panels is relatively long, and the early strength is low. SUMMARY According to various embodiments of the present application, a reinforced magnesium substrate and a composite board with the same are provided.
