Problems solved by technology

Although it can meet the use of general suspended ceilings and partition walls, its strength cannot meet the requirements when it is used as a floor slab.
For example, a sandwich floor slab made of magnesium oxide board (magnesia board is the core material, and the cladding panel is reinforced by three layers of glass fiber cloth, the thickness is 12mm, and the total thickness is 120mm) is tested, and the load is 180kg / m 2 , its strength cannot reach 200kg / m 2 Therefore, the traditional glass magnesium board has great limitations when used as an exterior wall or floor slab

Embodiment 1

[0022] Using a width of 1.3 meters, specifications 8 × 8 (mm) or 7 × 5 (mm) glass fiber cloth

[0023] Wire mesh: φ3mm, 50×70(mm) square holes

[0024] The thickness of the steel mesh reinforced anti-theft glass magnesium sheet made according to the above-mentioned method of the present invention is 12mm.

[0025] Performance test: Fire performance: GB / 8627, Class A non-combustible, fire resistance limit ≥ 3 hours.

[0026] Sound insulation performance: ≥40dB

[0027] The steel mesh-reinforced anti-theft glass magnesium sheet is used as the cladding panel, and the sandwich is made of flame-retardant paper honeycomb to make a floor slab of 120mm (thickness)×120mm (width)×300mm (length), and the bending load is 480kg / m 2 , 2 times higher than the bending load of the floor made of traditional glass magnesium board.

Embodiment 2

[0029] According to embodiment 1, adopt φ 4mm, the steel wire mesh of 50 * 70 (mm) grid makes the anti-theft glass magnesium thin plate that the steel mesh of 12mm thick strengthens, uses the anti-theft glass magnesium thin plate that this steel mesh strengthens as cladding panel, sandwich adopts resistance Combustion paper honeycomb made of 120mm (thickness) × 120mm (width) × 300mm (length) of the floor, the bending load is 480kg / m 2 The thermal resistance is 1.1W / M.K, the sound insulation performance is ≥45dB, and the density is 42kg / m 2 , and the density of the SP (steel reinforced cement) floor slab reaching the same strength is 200kg / m 2 , the bending load is 2.6 times higher than that of the floor slab made of traditional glass magnesium board, and the weight is 1 / 5 of the SP board.

Embodiment 3

[0031] According to embodiment 1, adopt φ 6mm, the steel wire mesh of 50 * 50 (mm) grid makes the anti-theft glass magnesium thin plate that the steel mesh of 12mm thick strengthens, uses the anti-theft glass magnesium thin plate that this steel mesh strengthens as cladding panel, sandwich adopts resistance 120mm (thickness) exterior wall panel made of burning paper honeycomb, with a bending load of 480kg / m 2 , sound insulation performance ≥ 45dB, density 42kg / m 2 .

Abstract

An anti-theft steel mesh reinforced glass fiber and magnesium sheet comprises a magnesia daub body and a glass fiber cloth layer. The glass fiber cloth layer is compounded in the inside of the magnesia daub body. The steel mesh reinforced glass fiber and magnesium sheet is characterized in that one or a plurality of layers of steel wire mesh(es) is(are) compounded in the inside of the magnesia daub and the thickness of the whole sheet is 5mm to 20mm. The invention has the advantages of higher bearing force, anti-theft performance, mechanized manufacturing, stable quality, smooth sheet surface, high manufacture efficiency, and particular suitability for the outer walls and floor slabs of a building.

Description

technical field [0001] The invention relates to the field of magnesium oxide fireproof board and its manufacturing technology. Background technique [0002] Magnesium oxide board, commonly known as fireproof board, is mainly made of mixed cement composed of magnesium oxide, magnesium chloride, fillers and additives, and glass fiber cloth and non-woven fabric as reinforcing materials. The product not only has excellent fireproof performance, but also has high strength, which is much better than paper-faced gypsum board in terms of fireproof, waterproof and strength, so it has been widely popularized and applied. [0003] When the traditional magnesium oxide board is damaged by mechanical impact, it is very easy to have large holes due to damage and fragmentation, and it does not have anti-theft performance when used as a partition board. Although it can meet the use of general suspended ceilings and partition walls, its strength cannot meet the requirements when it is used a...
