Embodiment 1

[0018] Such as figure 1 and figure 2 Shown is the structural schematic diagram and cross-sectional view of the fluorogypsum lightweight sandwich panel of the present invention. The fluorogypsum lightweight sandwich panel is made by casting the fluorogypsum slurry surface layer material 2 on the polystyrene foam board 3 , There are two lateral grooves 4 on both sides of the sandwich panel for installation and use. Grinding and calcined fluorine gypsum powder, sulphoaluminate cement, sodium sulfate, and glass fiber are used as raw materials to mix uniformly in proportion, add water and stir to form a slurry, and use abrasive tools to cast on polystyrene foam boards. After the paste is completely hardened, it is released from the mold. The fluorogypsum lightweight sandwich panel surface material of the present invention is made of the following raw materials in parts by weight:

[0019] Fluorogypsum powder 100 parts

[0020] 3 parts sulphoaluminate cement

[0021] 1 part so...

Embodiment 2

[0028] The sandwich panel of the present embodiment is basically the same as the first embodiment, and its raw material ratio is:

[0029] Fluorogypsum powder 100 parts

[0030] 4 parts sulphoaluminate cement

[0031] Sodium Sulfate 2 parts

[0032] 0.9 parts of glass fiber

[0033] Water to material ratio 0.8

[0034] The size of the fluorogypsum lightweight sandwich panel produced is 3000mm×600mm×90mm, and the technical performance test results are shown in Table 2.

Embodiment 3

[0038] The sandwich panel of the present embodiment is basically the same as the first embodiment, and its raw material ratio is:

[0039] Fluorogypsum powder 100 parts

[0040] 6 parts of sulphoaluminate cement

[0041] Sodium Sulfate 2 parts

[0042] 1.2 parts of glass fiber

[0043] Water to material ratio 0.9

[0044] The size of the fluorogypsum lightweight sandwich panel produced is 2500mm×600mm×120mm, and the technical performance test results are shown in Table 3.

Abstract

The invention belongs to the technical field of gypsum building materials, and relates to a light-weight laminboard, which is manufactured by compositing a surface course material mainly prepared from ground and calcined fluorgypsum on a polystyrene plastic foam board core material, and of which both sides are provided with grooves. In the laminboard, the surface course material coated outside a polystyrene plastic foam board is prepared from the following raw materials in part by weight: 100 parts of fluorgypsum powder, 2 to 6 parts of sulphoaluminate cement, 1 to 3 parts of sodium sulfate and 0.5 to 1.5 parts of glass fibers, wherein the ratio of water to the raw materials is 0.50-1.0. The product performance reaches national quality standards; and the fluorgypsum light-weight laminboard has the functions of light weight, high strength, heat preservation, heat insulation, sound insulation and the like, and is a walling material which can be applied to buildings with frame structures.

Description

technical field [0001] The invention belongs to the technical field of gypsum building materials, and relates to a light-weight sandwich board for frame structure buildings made of treated fluorogypsum. Background technique [0002] Most of the traditional wall materials are solid clay bricks, which not only consume a lot of energy, but also seriously damage the cultivated land. In recent years, with the implementation of national policies such as restricting and prohibiting the use of solid clay bricks, various new wall materials have emerged in an endless stream. At present, the frame structure building has quietly risen in our country, and it is getting hotter and hotter. The enclosure wall is the main component of the frame structure building. In the frame structure building, the wall body is required to have light weight, heat insulation, sound insulation, impact resistance, fire prevention and other properties. Lightweight wall materials used as enclosure walls of fr...
