Decorative plate and manufacturing method of the decorative plate

Abstract

The invention discloses a decorative plate and a manufacturing method of the decorative plate. The decorative plate comprises a first inorganic slurry layer, a second inorganic slurry layer and a third inorganic slurry layer filled with a closed-pore light filler, the third inorganic slurry layer filled with the closed-pore light filler comprises a mounting surface and a binding surface which arearranged back to back, the first inorganic slurry layer is installed on the installation face in a covering mode, the second inorganic slurry layer is installed on the attachment face in a covering mode, and the vertical distances from all points on the face, back on to the installation face, of the first inorganic slurry layer to the face, back on to the attachment face, of the second inorganic slurry layer are constant values. According to the decorative plate and the manufacturing method of the decorative plate, the structural stability of the decorative plate is improved, the accuracy anduniformity of the thickness of the decorative plate are improved, the nailing capacity of the decorative plate is improved, the plate has a flat and smooth surface through selection of low-fineness modulus slurry, and meanwhile the possibility that a structural part is embedded into the plate is provided.

Description

technical field [0001] The invention relates to the technical field of architectural decoration, and more specifically, to a decorative board and a method for manufacturing the decorative board. Background technique [0002] At present, there are many types of inorganic fireproof materials for decoration on the market. The surface of inorganic fireproof boards such as cement fiberboard and calcium silicate board is relatively smooth, but they have the disadvantages of high density, high water absorption and poor dimensional stability. This type of inorganic board can reduce the density of the board by adding a foaming agent to increase the foaming degree, but the board prepared by this method is porous inside and the strength is reduced. When screwing, the board at the screw is easy to shatter , forming a volume defect. When re-nailing for many times, the plate at this position is easy to loosen and fall off during nailing, and it is not feasible to nail. At the same time, ...

Problems solved by technology

[0002] At present, there are many types of inorganic fireproof materials for decoration on the market. The surface of inorganic fireproof boards such as cement fiberboard and calcium silicate board is relatively smooth, but it has the disadvantages of high density, high water absorption and poor dimensional stability.

This kind of inorganic board can reduce the density of the board by adding a foaming agent to increase the foaming degree, but the board prepared by this method is porous inside and the strength is reduced. When screwing, the board at the screw is easy to shatter , forming a volume defect

When re-nailing for many times, the plate at this position is easy to loosen and fall off during nailing, and it is not feasible to nail. At the same time, foaming reduces weight and causes the plate to have high water absorption, uneven surface, and easy deformation. Shortcomings
