Problems solved by technology

[0002] Decorative gypsum ceiling has been used for a long time as a common indoor ceiling decoration material, and its production technology has also matured. People can only produce products with a width of less than 600mm and a length of less than 1800mm. If the size is larger, the sagging deflection is too large to meet the requirements of use.

Embodiment 1

[0024] refer to figure 1 , the large-size light-weight decorative gypsum ceiling (1200*1200*18mm) of this embodiment includes a gypsum ceiling body, and the first layer of glass fiber felt 1, glass fiber grid cloth 2, glass fiber Rod 3, aluminum alloy keel 4 and second layer of glass fiber mat 5, the first layer of glass fiber mat 1 is located at the bottom of the gypsum ceiling body, and the glass fiber mesh cloth 2 is located above the first layer of glass fiber mat 1 , the glass fiber rods 3 are four, evenly distributed around the gypsum ceiling body, and wrapped by the first layer of glass fiber felt 1, the aluminum alloy keel 4 is located above the glass fiber grid cloth 2, the first The two-layer glass fiber mat 5 is located on the top of the gypsum ceiling body, and wraps the aluminum alloy keel 4 and the glass fiber rod 3 .

[0025] In this embodiment, there are two aluminum alloy keels 4, which are evenly distributed in the main body of the gypsum ceiling.

[0026] ...

Embodiment 2

[0037] The large-size lightweight decorative gypsum ceiling of this embodiment is 1200*2400*18mm, and its structure differs from that of Embodiment 1 in that the number of aluminum alloy keels is five.

[0038] Its preparation method comprises the following steps:

[0039] (1) Take by weighing 18 kilograms of gypsum powder, pour it into a stirring bucket filled with 12.6 kilograms of water while shaking, stir after soaking the powder for 30 seconds, and obtain a gypsum slurry;

[0040] (2) Take gypsum slurry (4 liters), pour it into the PVC mold, smooth it, and do not expose the bottom;

[0041] (3) Lay the first layer of glass fiber felt (1.3*2.5 meters), and level it out so that the slurry overflows evenly;

[0042] (4) Pour the slurry (4 liters) into the PVC mold again, smooth it, lay the glass fiber mesh cloth (1.2*2.4 meters), and smooth it again, so that the slurry evenly soaks the glass fiber mesh cloth;

[0043] (5) Pour the slurry (4 liters) into the PVC mold again,...

Abstract

The invention discloses a large-size light decorative gypsum ceiling and a preparation method thereof. The gypsum ceiling comprises a gypsum ceiling body, wherein a first layer of glass fiber felts, glass fiber gridding cloth, glass fiber rods, aluminum alloy keels and a second layer of glass fiber felts are arranged in the gypsum ceiling body; the first layer of glass fiber felts is positioned at the bottom of the gypsum ceiling body; the glass fiber gridding cloth is positioned above the first layer of glass fiber felts; four glass fiber rods are provided, are uniformly distributed at the periphery of the gypsum ceiling body, and are wrapped by the first layer of glass fiber felts; the aluminum alloy keels are positioned above the glass fiber gridding cloth; and the second layer of glass fiber felts is positioned at the top of the gypsum ceiling body, and wraps the aluminum alloy keels and the glass fiber rods. The invention further comprises the preparation method of the large-size light decorative gypsum ceiling. As the decorative gypsum ceiling structure is changed, the decorative gypsum ceiling of 1200*1200 mm-1200*2400 mm can be produced; and the decorative gypsum ceiling is specifically suitable for large buildings with large-area ceilings.

Description

technical field [0001] The invention relates to a decorative gypsum ceiling and a preparation method thereof, in particular to a large-size lightweight decorative gypsum ceiling and a preparation method thereof. Background technique [0002] Decorative gypsum ceiling has been used for a long time as a common indoor ceiling decoration material, and its production technology has also matured. People can only produce products with a width of less than 600mm and a length of less than 1800mm. If the size is larger, the sagging deflection is too large to meet the requirements of use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a decorative gypsum ceiling with a size of 1200*1200mm-1200*2400mm or even larger and a preparation method thereof. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] The large-size light-weight decorative gypsum ceiling of the pres...
