The heat conductivity coefficient of the heat-insulating wallboard manufactured by the vacuum heat-insulating board is obviously reduced, and the thickness is reduced. The precondition of the vacuum insulation panel is to ensure that the vacuum degree is not destroyed, however, in the process of installing the heat insulation wallboard on a construction site, an anchor bolt and a wall penetrating rib are required to be penetrated on the heat insulation wallboard. The vacuum packaging area of the traditional vacuum insulated panel is large, and when the vacuum insulated panel is damaged by punching, the whole vacuum degree of the vacuum insulated panel is damaged, and the vacuum heat insulation performance is lost. Therefore, how to avoid the damage of the anchor bolts and the wall penetrating ribs to the vacuum degree of the vacuum insulation panel is a problem to be solved in order to ensure that the vacuum insulation panel normally plays a role in heat preservation.
The prior art discloses some vacuum insulation panels applied to walls, which can reduce the damage of punching or cutting to the vacuum degree of the whole panel to a certain extent after dividing the whole panel into a plurality of independent small-size units, but the existing vacuum insulation panels are unreasonable in structural design for realizing the separation of the small-size units, gaps among the small-size units are usually filled with common materials, so that the gaps do not have vacuum insulation performance, the insulation performance of the whole panel is further influenced, and the insulation performance of the vacuum insulation panels is not fully exerted.

Detailed Description
In order to clearly illustrate the technical features of the present solution, the present utility model will be described in detail below with reference to the following detailed description and the accompanying drawings.
It should be noted that in the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model, however, the present utility model may be practiced in other ways than as described herein. Therefore, the scope of the utility model is not limited by the specific embodiments disclosed below.
Example 1:
as shown in fig. 1 and 8, the vacuum insulation composite board capable of cutting and punching provided by the utility model comprises a first vacuum insulation board 100 and a second vacuum insulation board 200 which are stacked with the board surfaces thereof being in contact with each other. The solid line box in the figure shows the vacuum module of the first vacuum insulation panel 100, and the dotted line box shows the vacuum module of the second vacuum insulation panel 200.
The first vacuum insulation panel 100 and the second vacuum insulation panel 200 each include a plurality of vacuum modules 300 arranged in a rectangular array along a panel direction at intervals, and each vacuum module 300 is formed by vacuum-pumping and sealing a core unit 310 between two layers of gas barrier film sheets 320. By the arrangement, the first vacuum insulated panel 100 and the second vacuum insulated panel 200 are respectively composed of the vacuum modules 300, the heat conductivity coefficient of each vacuum module 300 is very low, and compared with the traditional heat insulation board, the heat insulation performance of the vacuum insulated panel provided by the utility model is obviously improved. Moreover, because each vacuum module 300 is independently vacuumized and sealed, when the later heat insulation plate is perforated or cut, the vacuum degree of the corresponding vacuum module 300 is only damaged, and the vacuum degree of other vacuum modules 300 is not influenced, so that the influence on the integral heat conductivity coefficient of the whole heat insulation plate is reduced, and the heat insulation performance of the heat insulation plate is ensured.
After each vacuum module 300 is arranged in an array, the space gaps between adjacent vacuum modules 300 are not filled or covered by heat insulation materials, and heat is easily conducted along the space gaps in the thickness direction, so that the heat conductivity coefficient of the space gap is high, a heat bridge is formed, and the overall heat insulation performance of the heat insulation plate is further affected. For this reason, as shown in fig. 1 and 8, the present utility model applies to stagger the gap between the respective vacuum modules 300 of the first vacuum insulation panel 100 and the gap between the respective vacuum modules 300 of the second vacuum insulation panel 200 in the plate thickness direction. In this way, the spacing seams of the two insulating boards are staggered, so that the position of the first vacuum insulating board 100 for filling the core material unit 310 is just pressed on the spacing seam of the second vacuum insulating board 200, and the position of the second vacuum insulating board 200 for filling the core material unit 310 is just pressed on the spacing seam of the first vacuum insulating board 100. Accordingly, in the plate thickness direction, heat will be blocked by the second vacuum insulation panel 200 after being transferred along the slit of the first vacuum insulation panel 100, and heat will be blocked by the first vacuum insulation panel 100 after being transferred along the slit of the second vacuum insulation panel 200, blocking the thermal bridge effect.
Example 2:
although the gap between the two insulation boards can be blocked by each other, the effective insulation board thickness at the gap position is smaller than that at other positions, and in order to solve the problem, as shown in fig. 2 and 9, the present embodiment is modified based on embodiment 1 as follows:
on the outer plate surface of each core unit 310 of the first vacuum insulation panel 100, a heat insulation bar 400 is laid, the position of the heat insulation bar 400 being opposite to the gap between the respective vacuum modules 300 of the second vacuum insulation panel 200 in the plate thickness direction, the heat insulation bar 400 being vacuum-sealed within the vacuum modules 300 together with the corresponding core unit 310. After the heat insulating strips 400 are provided, the effective insulation panel thickness corresponding to the gap positions of the second vacuum insulation panel 200 is increased in the panel thickness direction, and the thermal conductivity of the insulation panel corresponding to the gap positions of the second vacuum insulation panel 200 is further reduced. In addition, after the heat insulating strips 400 are arranged on the first vacuum heat insulating plate 100, the surface of the first vacuum heat insulating plate 100 is uneven, so that the plate surface is easier to be pasted, and the composite strength of the vacuum heat insulating plate and the protective layer or the wall body is improved.
In general, the thickness of the core unit 310 of the first vacuum insulation panel 100 and the second vacuum insulation panel 200 is generally 1.5cm, and the thickness of the insulation bar 400 is generally 1.5cm. The stacked parts of the core material units 310 form a total thickness of 3cm, and the spacing seam parts are also stacked by the core material units 310 with the thickness of 3cm and the heat insulation strips 400 with the thickness of 1.5cm, so that the effective heat insulation thickness of all parts is ensured to be the same.
Example 3:
in this embodiment, on the basis of embodiment 2, a heat insulating strip 400 is further laid on the outer side plate surface of each core unit 310 of the second vacuum insulation panel 200, the position of the heat insulating strip 400 being opposite to the gap between the respective vacuum modules 300 of the first vacuum insulation panel 100 in the plate thickness direction, the heat insulating strip 400 being vacuum-sealed in the vacuum modules 300 together with the corresponding core unit 310. In this way, the effective insulation panel thickness corresponding to the gap position of the first vacuum insulation panel is also increased in the panel thickness direction, further reducing the thermal conductivity of the insulation panel corresponding to the gap position on the first vacuum insulation panel 100.
The insulation bars 400 may be sized slightly larger than the width of the gap, typically 2cm wide and 3cm wide.
As shown in fig. 2 and 9, after the vacuum modules are arranged in an array, a transverse and a vertical interval are formed, so that transverse and vertical heat insulation strips are required to be arranged to cover the interval in the corresponding direction.
Example 4:
the vacuum modules 300 constituting the first vacuum insulation panel 100 and the vacuum modules 300 constituting the second vacuum insulation panel 200 may have different configurations. As shown in fig. 3 and 4, in the present embodiment, the first vacuum insulation panel 100 (fig. 3) and the second vacuum insulation panel 200 (fig. 4) are formed by simultaneously wrapping all the core material units 310 between two gas barrier film sheets 320 and then vacuum sealing, and the two gas barrier film sheets 320 are sealed at the edge portions and the portions corresponding to the gaps by hot melt lamination.
For example, when the first vacuum insulation panel 100 is manufactured, each core unit 310 is arranged on the lower gas barrier film 320, the heat insulation strips 400 are laid on each core unit 310, then the upper gas barrier film 320 is laid, after the two gas barrier films 320 are partially hot-melt pressed and sealed at the edge portions or the gap portions of the core units 310, the air between the gas barrier films 320 and in the core units 310 can be pumped out by using a vacuumizing device, and then the remaining edge portions and the gap portions of the two gas barrier films 320 are completely sealed, thereby completing the processing of the first vacuum insulation panel 100. The second vacuum insulation panel 200 is processed by the same method. Then, as shown in fig. 5 and 6, the first vacuum insulation panel 100 and the second vacuum insulation panel 200 are staggered and stacked so that the corresponding insulation bars of the space slits on the first vacuum insulation panel 100 and the second vacuum insulation panel 200 are shielded. The first vacuum insulation panel 100 and the second vacuum insulation panel 200 provided in this embodiment have simple structures and are easy to produce.
Generally, the size of the vacuum heat insulation composite heat preservation plate capable of being cut and perforated is about 300cm multiplied by 120 cm. During production, 6 small plates with the size of 300cm multiplied by 20cm are respectively processed, the small plates with the size of 300cm multiplied by 20cm are transversely spliced to form a large plate with the size of 300cm multiplied by 120cm, and then the large plates are composited to form the first vacuum heat insulation plate 100, the second vacuum heat insulation plate 200 and the integral vacuum heat insulation composite heat insulation plate capable of being cut and punched.
The method for processing each 300cm multiplied by 20cm small plate comprises the following steps: core material units 310 with the size of 8cm multiplied by 8cm are arranged between two layers of gas barrier film 320 in a 2 multiplied by 30 array mode, the width of a gap between the core material units 310 is 2cm, the two layers of gas barrier film 320 are subjected to hot melting and pressing at the gap between the core material units 310, then vacuum is pumped, and finally the edge parts of the two layers of gas barrier film 320 are subjected to hot melting and pressing and sealing.
Example 5:
as shown in fig. 9 and 10, in the present embodiment, each core unit 310 constituting the first vacuum insulation panel 100 and each core unit 310 constituting the second vacuum insulation panel 200 are individually wrapped with one internal air-blocking pouch, each of which is formed by sealing two air-blocking films 320 at the edge portion, and then vacuum-sealed. The vacuum modules of the first vacuum insulation panel 100 and the second vacuum insulation panel 200 are shown in fig. 9 and 10, respectively.
For example, in the production of the first vacuum insulation panel 100, it is necessary to produce individual vacuum modules 300 first. The production method of each vacuum module 300 is as follows: the edge portions of the two gas barrier film sheets 320 are partially sealed to form an internal gas barrier bag, the heat insulation strips 400 are fixed at the corresponding positions of the core material units 310 and then are together arranged in the internal gas barrier bag, then the internal gas barrier bag, the core material units 310 and the air in the heat insulation strips 400 are pumped out, and finally the internal gas barrier bag is sealed to form the vacuum module 300. Then, the respective vacuum modules 300 are arranged to a size of one large heat insulating plate, and the respective vacuum modules 300 constituting the first vacuum heat insulating plate 100 or the second vacuum heat insulating plate 200 may be further bonded to each other to form a whole or vacuum-pumped in one large air blocking bag to form a whole, thus forming the first vacuum heat insulating plate 100 and the second vacuum heat insulating plate 200. The structure of the vacuum module 300 provided in this embodiment needs to be assembled by arranging each vacuum module 300 after being produced separately, and the product structure and the production process are more complicated than those of embodiment 4, but the gap width between the vacuum modules is smaller.
For the above embodiments 1 to 5, after the first vacuum insulation panel 100 and the second vacuum insulation panel 200 are stacked as required to form a vacuum insulation composite thermal insulation panel capable of being cut and perforated, for convenience of transportation and installation, it is preferable that the first vacuum insulation panel 100 and the second vacuum insulation panel 200 are compositely fixed by some means. For example, the bonding and fixing may be performed by coating an adhesive material on the contact plate surfaces of the two insulation plates, but it is preferable to use a method of wrapping the first vacuum insulation plate 100 and the second vacuum insulation plate 200 in the same external air-blocking bag 500 after being stacked, vacuumizing, and hot-melting, pressing and sealing. In the hot-melt bonding process, the outer air-blocking bag and the air-blocking film 320 on the surface of the vacuum module 300 are also combined together by hot-melt bonding, so that the first vacuum insulation panel 100 and the second vacuum insulation panel 200 are combined to form an integral plate. In fig. 1 and 7, the outer large box shows an outer airbag.
Further, when the first vacuum insulation panel 100 and the second vacuum insulation panel 200 are arranged in a staggered manner, it is preferable to adopt a staggered manner in which each vacuum module 300 of the first vacuum insulation panel 100 and each vacuum module 300 of the second vacuum insulation panel 200 are shifted in a diagonal direction parallel to the panel surface.
As shown in fig. 11, for the above embodiments 1 to 5, the outer side plate surfaces of the first vacuum insulation panel and the second vacuum insulation panel, which are away from each other, are further provided with a first protection layer and a second protection layer in sequence, the first protection layer is embedded with a steel wire mesh, the second protection layer is embedded with an alkali-resistant glass fiber mesh, and the overall strength of the composite insulation panel is ensured by the cladding of the first protection layer and the second protection layer.
Further, the first protective layer is formed by curing polyphenyl particle thermal insulation mortar, and the second protective layer is formed by curing polymer mortar.
In the present application, the core unit 310 and the gas barrier film 320 of the vacuum module 300 are made of conventional materials commercially available in the art, for example, the gas barrier film 320 may be made of aluminum foil or glass fiber composite material, and the core unit 310 and the heat insulation strip 400 may be made of microporous core filled with fumed silica.
