[0002] With the development of technology, more and more types of boards have emerged in the board industry. New types of boards have replaced traditional solid wood boards. Traditional wood is directly processed from lumber, while the current composite boards have solved the shortcoming of traditional wood being flammable. The fire prevention problem of plywood has always been an important topic in the construction field. In recent years, different types of fire-proof board products such as fire-proof boards and fire-proof doors have appeared on the market.

[0003] Most of the existing composite multi-layer boards are flame-retarded by coating a fire-proof coating on the surface of the board. However, during long-term use, if the coating on its surface is damaged, the flame-retardant performance of the composite multi-layer board will be reduced. At the same time, the corners of the composite multi-layer board are easily damaged during transportation. Therefore, a new type of flame-retardant composite multi-layer board is proposed for the above problems. Summary of the Utility Model
