Abstract

The invention relates to a composite magnesite board and a production method. The composite magnesite board comprises a frame and magnesite boards adhered to both sides of the frame, wherein the inside of a cavity enclosed by the frame and the magnesite boards is fully clamped with a foam board, and contact surfaces of the foam board and the magnesite boards are adhered to each other. According to the proposal, the inside of a hollow structure of the frame is filled with the foam board which is loose and porous and can absorb water vapor in the air to the ambient environment, thereby effectively inhibiting the recurrent halogen and the recurrent milk; in addition, no hollow structure exists between two layers of the magnesite boards after the foam board is filled, so the strength of the boards is increased.

Description

technical field

[0001] The invention relates to a magnesite composite board and a production method. Background technique

[0002] In modern buildings, lightweight materials are very popular, especially for high-rise buildings with frame structures, most of which use lightweight profiles for their interior walls. At present, there is a kind of magnesite composite board used as a lightweight profile board, which includes a frame and magnesite boards fixed on both sides of the frame. The composite board of this structure is a hollow structure. The magnesite material contains magnesium chloride. The biggest disadvantage of magnesium chloride is the phenomenon of halogen return when it is wet. As a result, the board will return to halogen and milk due to moisture and other reasons when it is used. Water droplets appear on the surface of the magnesite board, resulting in blistering of the paint layer. , cracks, will also cause the deformation of the magnesite board, affect the a...

Embodiment Construction

[0020] figure 1 , 2 Embodiment 1 of the magnesite composite board of the present invention shown, comprises frame 1, is provided with reinforcing support bar between four frames of frame 1, is fully filled with foam board 2 in the hollow structure of frame 1, each face of foam board 2 is uniform It is flush with the end face of the frame 1, and the front and rear end faces of the frame 1 are bonded with magnesite plates 6. The size of the magnesite plate 6 matches the frame 1, and the outer layer of the magnesite plate 6 is bonded with The solid wood surface 5 of the plate 6 coincides.

[0021] image 3 Shown is a cross-sectional view of Embodiment 2 of the magnesite composite board of the present invention, which is different from Embodiment 1 in that the frame 1 has only surrounding frames, and there is no reinforcing support bar between every two opposite frames.
