Embodiment 1

[0027] A kind of wall vacuum insulation board, refer to figure 1 , including a powder layer 10, a non-woven fabric bag 20, a high-barrier packaging bag 30, an adhesive 40 and a fiber-reinforced composite barrier bag 50 from the inside to the outside, and its preparation method is as follows:

[0028] Step 1, the fumed white carbon black powder that has been mixed uniformly quantitatively, glass fiber (its diameter is 7 μ m) is packed in the non-woven fabric bag 20 according to mass ratio 110:5, is placed in the molding machine that has set Extrude in the middle to obtain the heat insulation core material of the required size, put the heat insulation core material in an oven to dry, and set aside;

[0029] Step 2: Take out the dried core material from the oven and quickly put it into the high-barrier packaging bag 30, and perform a vacuum seal in a vacuum sealing machine, the vacuum degree of which is greater than 0.1 Pa during sealing, to obtain a vacuum insulation panel;

Embodiment 2

[0033] A kind of wall vacuum insulation board, refer to figure 2 , comprising a powder layer 10, a non-woven fabric bag 20, a high-barrier packaging bag 30, an adhesive 40, glass fiber reinforced plastics 60 and a fiber-reinforced composite barrier bag 50 from the inside to the outside in sequence, and its preparation method is as follows:

[0034] Step 1, the fumed white carbon black powder that has been mixed uniformly quantitatively, glass fiber (its diameter is 7 μ m) is packed in the non-woven fabric bag 20 according to mass ratio 110:5, is placed in the molding machine that has set Extrude in the middle to obtain the heat insulation core material of the required size, put the heat insulation core material in an oven to dry, and set aside;

[0035] Step 2: Take out the dried core material from the oven and quickly put it into the high-barrier packaging bag 30, and perform a vacuum seal in a vacuum sealing machine, the vacuum degree of which is greater than 0.1 Pa during ...

Embodiment 3

[0039] The difference from Example 2 is that the fiber-reinforced composite barrier bag has heat shrinkability. After the wall vacuum insulation board is prepared in step 4, the wall vacuum insulation board is placed in an oven at 65-70°C for 10-15 seconds, and it is ready to take out. Can.

Abstract

The invention relates to the field of building energy-saving insulation, in particular to a wall body vacuum insulation plate and a preparation method thereof. The wall body vacuum insulation plate comprises a vacuum heat isolation plate formed by a high isolation package bag and an insulation core material arranged in the high isolation package bag through vacuum sealing, and a fiber reinforced composite isolation bag is arranged outside the vacuum heat isolation plate in a seal and vacuum mode. Compared with the prior art, due to the fact that the fiber reinforced composite isolation bag is arranged outside the vacuum heat isolation plate in the seal and vacuum mode, abrasion resistance, fire-proof performance and bonding performance with other materials of the wall body vacuum insulation plate are reinforced. The wall body vacuum insulation plate is particularly suitable for being used in the field of building energy-saving insulation, not only can be applied to external wall insulation, internal wall insulation and sandwich insulation, but also can be applied to thin-plastered and various decorating dry-hanging systems, and is particularly suitable for energy-saving buildings which have high requirements for heat insulation in cold areas.

Description

technical field [0001] The invention relates to the field of building energy saving and heat preservation, in particular to a wall vacuum heat preservation board and a preparation method thereof. Background technique [0002] Vacuum insulation panel (Vacuum Insulation Panel, referred to as VIP) is a kind of super heat insulation material. It adopts the method of vacuuming to pump out the gas in the heat insulation space, so that the various heat transfer channels caused by the gas are weakened or even eliminated. To the effective heat shielding effect, so that its heat insulation effect is far better than ordinary heat insulation materials. [0003] The development of the construction industry in the 21st century should focus on building energy conservation and emission reduction, and insist on combining energy conservation and emission reduction with technological innovation. One of the main measures for building energy saving is to widely use insulation products with low ...
