Problems solved by technology

Since the existing vacuum insulation panels are all flat structures, they are often not suitable for complex building components
In addition, because the surface of the aluminum-plastic composite bag used in the existing vacuum insulation panels is covered with glass fiber cloth, the surface of the product is a smooth structure, and the bonding force with the mortar used for bonding is poor, and it is affected by factors such as construction operations and external forces. Affected, vacuum insulation panels are prone to hollowing and falling off
In addition, the vacuum insulation panel will inevitably break the bag and leak due to external force during transportation, the effective use rate of the product is low and there are certain safety hazards

Embodiment 1

[0040] Embodiment 1 A kind of special-shaped external wall insulation board such as Figure 1 to Figure 3 As shown, the cross-section is arc-shaped.

[0041] The outer wall thermal insulation board with an arc-shaped cross section includes an arc-shaped vacuum heat insulation board, and the arc-shaped vacuum heat insulation board is made of an arc-shaped inorganic heat preservation core material board 1 and is covered with a vacuum insulation board. The thermal bag 3 is composed of an arc-shaped vacuum insulation panel covered with a shell 2 made of inorganic heat-insulating material, and the arc-shaped inorganic heat-insulating core board 1 is made of inorganic fiber material, and the inorganic fiber material is rock wool or Glass fiber, the material of the protective shell 2 formed by the inorganic heat-resisting material is foamed cement.

[0042] The method of the present invention's production embodiment 1 arc-shaped outer wall insulation board, as Figure 8 to Figure 1...

Embodiment 2

[0057] Embodiment 2 A kind of special-shaped external wall insulation board such as Figure 4 to Figure 7 As shown, the cross-section of the external wall insulation board is L-shaped.

[0058] The production method of embodiment 2 is identical with the production method of embodiment 1, and embodiment 2 is compared with embodiment 1, only the shape of vacuum insulation board and mold inner cavity is different, as Figure 18 to Figure 19 shown.

[0059] The cross-section of the special-shaped external wall insulation board of the present invention is not only arc-shaped or L-shaped, but also other special-shaped geometric shapes can be adopted according to the needs of building components.

Abstract

The invention discloses a special-shaped outer wall insulation board. The insulation board comprises a special-shaped vacuum insulation board, wherein a special-shaped inorganic insulation core material board is coated with a vacuum insulation bag to form the special-shaped vacuum insulation board, the special-shaped vacuum insulation board is coated with an inorganic insulation layer, the special-shaped inorganic insulation core material board is made of rock wool or glass fiber, and the inorganic insulation layer is made of foaming cement. A production method of the special-shaped outer wall insulation board comprises the steps of producing the inorganic insulation core material board, placing the inorganic insulation core material board into the vacuum insulation bag and pumping the bag into vacuum with an absolute pressure ranging between 50Pa and 20Pa; fixing the vacuum insulation board by a special-shaped low thermal conductivity support; placing the special-shaped vacuum insulation board into an inner cavity of a mold; pouring foaming cement into the inner cavity of the mold; storing for 8-16 hours in a condition of drying in shade; and disassembling the mold, fetching out the special-shaped outer wall insulation board, and conducting water spraying maintenance for 20 days. The insulation board is applicable to complex construction components, the product and mortar can be combined well, the insulation effect is good, the fireproof performance is good, the insulation board is easy to transport and install, the production process is simple, and the cost is low.

Description

technical field [0001] The invention relates to an external wall thermal insulation board and a production method thereof, in particular to a special-shaped external wall thermal insulation board and a production method thereof. Background technique [0002] At present, some of the existing external wall insulation panels on the market use vacuum insulation panels. The vacuum insulation panel is to put the core material board and getter into the aluminum-plastic composite bag, and the outer surface of the aluminum-plastic composite bag is covered with glass fiber cloth. , and then vacuumed and sealed in an aluminum-plastic composite bag. Since the existing vacuum insulation panels are all flat structures, they are often not suitable for complex building components. In addition, because the surface of the aluminum-plastic composite bag used in the existing vacuum insulation panels is covered with glass fiber cloth, the surface of the product is a smooth structure, and the bo...
