Reinforced magnesium substrate and composite board with same

Abstract

Disclosed are a reinforced magnesium substrate and a composite board with the same. The reinforced magnesium substrate includes the following components in parts by weight: 240-280 parts of magnesium oxide, 172-192 parts of wood fiber, 1.3-3.5 parts of citric acid, 1.3-3.5 parts of phosphoric acid, 1.3-3.5 parts of sodium sulfate, 90-120 parts of magnesium sulfate and 109-130 parts of water. The composite board with the reinforced magnesium substrate includes the reinforced magnesium substrate, wood board layers and a wear-resistant layer. The reinforced magnesium substrate is configured as a board core of the composite board; the wood board layers are arranged on the two sides of the reinforced magnesium substrate respectively; and the wear-resistant layer is arranged on at least one wood board layer and relatively fixed with the wood board layer.
