Embodiment Construction

[0037] The present invention will be described in further detail below in conjunction with specific embodiments, but the protection scope of the present invention is not limited thereto. Example 1. A. Mix 10kg of magnesia powder, 11.25kg of 80-mesh cotton straw powder and 3.75kg of expanded perlite powder at normal temperature and pressure, and then pour it into a sealed kettle, and vacuum until the pressure inside the kettle is 0.5atm. Add 17.5 L of magnesium chloride solution with a concentration of 6 mol / L and a pH value of 7.0, and stir for 15 minutes to prepare a slurry. A layer of non-woven fabric is laid on the bottom layer of the plate making machine (Shandong Innovation Building Materials Complete Equipment Co., Ltd.), and 5 layers of glass fiber cloth are laid on the top of the non-woven fabric, and the resulting slurry is transported to the bottom of the plate making machine through a sealed delivery pipe. The feed port is coated on the surface of 5 layers of glass...

Abstract

The invention discloses a fire-proof decorative board manufacturing process. The fire-proof decorative board manufacturing process comprises the following steps: conducting cold pressing on a rolled plate by using a 600-1200 tons press at room temperature for 1-2 min; and feeding the cold-pressed plate into a curing room with temperature of 35-50 degrees centigrade to stand for 2-5 hours so as to obtain a fire-proof decorative board. The fire-proof decorative board manufacturing process disclosed by the invention has the advantages that the density and flatness of the decorative board can be obviously increased and the thickness error of the decorative board can be reduced. Compared with the decorative board which is not cold-pressed, the decorative board manufactured by the fire-proof decorative board manufacturing process has the advantages that the thickness error of the whole board can be reduced from 0.5-1 mm to 0.1 mm and the density of the decorative board can be also increased by more than 20%.

Description

technical field [0001] The invention relates to a manufacturing process of a fireproof decorative board. Background technique [0002] In architectural decoration and furniture manufacturing, decorative panels are widely used. Existing decorative panels are mainly made of wood, and their fire performance is poor. There is a high demand for non-combustible decorative panels. Moreover, the strength of existing decorative boards is usually not high, and cannot meet some special process requirements. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the existing decorative boards, the present invention provides a fireproof decorative board manufacturing process with good fire performance and high strength. The technical scheme adopted by the present invention is: [0004] A. Mix magnesium oxide powder, straw powder, and expanded perlite powder evenly under normal temperature and pressure, and then pour them into a sealed kettle; the...
