Embodiment 1

[0022] Example 1 A solidified cement sandwich panel

[0023] The solidified cement sandwich panel, such as figure 1 As shown, it includes cement mortar layer 2, honeycomb aluminum layer 1 and fiber mesh cloth 4. The cement mortar layer 2 is divided into an upper mortar layer and a lower mortar layer. The upper and lower sides of the honeycomb aluminum layer 1 are respectively solidified with an upper mortar layer and a lower mortar layer. The two cement mortar layers are filled with low-alkali glass fiber mesh cloth 4, and a layer of intersecting solidification layer 3 is formed between the cement mortar layer 2 and the honeycomb aluminum layer 1.

[0024] As an embodiment, the thickness of the upper mortar layer and the lower mortar layer is 8mm; the thickness of the honeycomb aluminum layer is 20mm.

Embodiment 2

[0025] Embodiment 2 A kind of preparation method of setting type cement sandwich panel

[0026] The preparation method is realized through the following steps:

[0027] First lay a layer of cement mortar a (laying thickness 8mm) in the prepared mold (size 1220×1220×25mm), and then lay a layer of fiber mesh cloth 1 (size 1200mm) on the laid cement mortar a ×1200mm), lay the first layer of honeycomb aluminum on the laid layer of fiber mesh cloth 1 (the laying thickness is 20mm), then put the mold and materials into the hydraulic press and pressurize until the honeycomb aluminum sinks into the mortar for 3mm and then stops , take off the mold after the cement mortar solidifies in the natural environment for 4 hours;

[0028] Lay a layer of cement mortar b (laying thickness is 8mm) in another forming mold (size is 1220×1220×33mm), and then lay a layer of fiber mesh cloth 2 (size is 1200× 1200mm), and then cover the above-mentioned completed cement board with honeycomb aluminum o...

Embodiment 3

[0034] Example 3 A preparation method of solidified cement sandwich panel

[0035] This preparation method, except following feature, other features are identical with embodiment 2:

[0036] The components of the cement mortar a and b are: 33.2% of cement, 39% of 40-70 mesh river sand, 25% of water, 0.5% of concrete water reducing agent, 0.30% of reinforcing fiber and 2% of thickener. Wherein, the cement is 52.5R ordinary cement.

[0037] The thickener adopts cellulose ether organic thickener.

[0038] The pressure of the hydraulic treatment is 28MPa.

[0039] The thickness of the cement mortar a and b is 5mm, and the thickness of the honeycomb aluminum can be 10mm.

Abstract

The invention discloses a solidified cement sandwich plate, which comprises a cement mortar layer, a honeycomb aluminum layer and fiber lattice cloth, wherein the cement mortar layer is divided into an upper mortar layer and a lower mortar layer; the upper mortar layer and the lower mortar layer are respectively solidified on the upper and lower surfaces of the honeycomb aluminum layer; a layer offiber lattice cloth fills in the two cement mortar layers; a crossing solidification layer is formed between the cement mortar layer and the honeycomb aluminum layer. The invention also discloses a preparation method of the solidified cement sandwich plate. The solidified cement sandwich plate and the method have the advantages that effects that the manufacturing process is simple; the money andequipment investment is low; the cost is low; the solidified cement sandwich plate made by the preparation method has the advantages of reduced water absorption rate, high intensity, good toughness, high durability and the like. Compared with a bonding mode using super glue, the solidified cement sandwich plate has the advantages that the environment-friendly effect is better; the intensity is higher; the bonding area of cement and honeycomb aluminum is deep and uniform, so that the influence of factors such as glue water aging, production glue coating nonuniformity, climate, temperature and humidity is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of building and decoration materials, and in particular relates to a solidified cement sandwich panel and a preparation method thereof. Background technique [0002] Cement sandwich panels play an important role in construction and decoration. It requires high strength, heat preservation, waterproof, fire prevention, and stable performance. Any single filler structure cannot meet the above requirements. [0003] Among the existing sandwich panel technologies on the market, wood wool cement sandwich panels or calcium silicate sandwich panels are adhesive sandwich panels bonded with superglue; Disadvantages such as swelling and deformation. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the invention provides a solidified cement sandwich panel. In the invention, before the cement is solidified, the honeycomb aluminum is uniformly pressed on the cement slurry, and after the ...
