Abstract

The invention relates to a transparent film for a vacuum heat insulation plate and a vacuum heat insulation composite plate. The transparent film for the vacuum insulation panel comprises a polyamide film layer, a low-density polyethylene layer and three barrier layers. The polyamide film layer, the low-density polyethylene layer and the three barrier layers are bonded and connected through adhesives. The barrier layer is made of vapor-deposited silicon oxide polyester film. The transparent film for the vacuum heat-insulating plate uses a pure transparent evaporated silicon oxide polyester film as a barrier layer of a product instead of a conventional aluminum-plated film and an aluminum foil, and prevents water vapor and oxygen from permeating into the vacuum heat-insulating plate. The pure transparent evaporated silicon oxide polyester film does not contain any metal component, so that the edge heat conduction caused by metal heat conduction is greatly reduced, and the barrier property can also reach that of an aluminum-plated film material containing the metal component.

In this embodiment, the transparent film includes a composite stacked polyamide film layer, a low density polyethylene layer, and a three-layer barrier layer, and is a multilayer film structure. The polyamide film layer, the low-density polyethylene layer and the three barrier layers are bonded and connected through adhesives. Referring to fig. 1, in fig. 1, 1 is a polyamide film layer, 2 is a barrier layer, and 3 is a low density polyethylene layer. In this example, the layers of the transparent film were arranged in the order of a polyamide film layer-a barrier layer-a low density polyethylene layer. Of course, in other embodiments, the transparent film layers may also be arranged in the order of barrier layer-polyamide film layer-barrier layer-low density polyethylene layer, or barrier layer-polyamide film layer-barrier layer-low density polyethylene layer, barrier layer-polyamide film layer-low density polyethylene layer.
In one embodiment, the vacuum insulation panel is manufactured by a dry lamination process using a transparent film.
Wherein, the specific gravity of each component is 14.01 to 15.76 percent of the polyamide film layer, 7.29 to 11.74 percent of the adhesive, 39.02 to 44.13 percent of the barrier layer and 30.87 to 37.28 percent of the low-density polyethylene layer respectively according to the weight ratio. In this example, the specific gravities of the respective components were 14.87% for the polyamide film layer, 9.33% for the binder, 42.13% for the barrier layer, and 33.67% for the low-density polyethylene layer. Of course, in other embodiments, the weight ratio of the polyamide film layer can be any of 14.01%, 15.76%, or 14.01-15.76%; the weight proportion of the adhesive can be any value of 7.29%, 11.74% or 7.29-11.74%; the weight ratio of the barrier layer can be any value of 39.02%, 44.13% or 39.02-44.13%; the low density polyethylene layer may be 37.28%, 30.87%, or 30.87-37.28% by weight.
In this example, the thickness of the polyamide film layer was 15 μm. The low density polyethylene layer may have a thickness of between 45 and 55 μm, in this example 50 μm. Of course, in other embodiments, the thickness of the heat-seal layer, i.e. the low-density polyethylene layer, may be 45 μm, may also be 55 μm, or may have other values in the range of 45-55 μm. The barrier layer is made of vapor-deposited silicon oxide polyester film, and has a thickness of 12-12.8 μm and a total thickness of 36-38 μm. In one of the embodiments, the thickness of the barrier layer may be set to 12 μm.
In one embodiment, the adhesive is a polyurethane glue to ensure that the film does not delaminate.
The performance of the transparent film was also tested in this example, while using an aluminum foil film and an aluminum-plated film for a conventional vacuum insulation panel on the market as a comparison. The details are as follows.

The heat diffusion coefficients of the transparent film, the aluminum foil film and the aluminum-plated film are obtained as shown in table 8 by comparing the data analysis tables of the transparent film, the aluminum foil film and the aluminum-plated film.
Table 8: heat diffusion coefficient table of transparent film, aluminum foil film and aluminum-plated film
Figure BDA0003187642710000083
The transparent film for the vacuum insulation panel of the embodiment uses the pure transparent evaporated silicon oxide polyester film layer to replace the prior aluminum-plated film layer and aluminum foil layer as the barrier layer of the product, so as to prevent water vapor and oxygen from permeating into the vacuum insulation panel; the excellent barrier property is obtained by using a mode of superposing and compounding 3 layers of evaporated silicon oxide polyester film layers; the pure transparent evaporated silicon oxide polyester film layer does not contain any metal component, so that the edge heat conduction caused by metal heat conduction is greatly reduced.
Example 2
The embodiment discloses a vacuum heat insulation composite board, which comprises a vacuum heat insulation board and a transparent film wrapped outside the vacuum heat insulation board; the transparent film used in example 1 was used as the transparent film for the vacuum insulation panel. The vacuum heat insulation composite board made of the transparent film can clearly see the conditions of the inner core materials, whether impurities exist, whether the arrangement is uniform and whether the core materials have defects or not, and is more favorable for acceptance and inspection of products.
The performance of the vacuum insulation composite panel was also tested in this example, and the commercial vacuum insulation panels including aluminum foil films and vacuum insulation panels including aluminum-plated films were used as a comparison. The details are as follows.
c. Test of plate thermal conductivity
The comparison test under normal temperature conditions shows the test results in table 9.
Table 9: test result table for heat conductivity coefficient of plate under normal temperature condition
Figure BDA0003187642710000091
Through comparison tests, the heat conductivity coefficient of the vacuum heat insulation composite board made of the transparent film is consistent with that of the vacuum heat insulation board made of the aluminum-plated film and is slightly lower than that of the vacuum heat insulation board made of the aluminum foil film under the condition that the vacuum heat insulation composite board is placed at normal temperature, so that the barrier property of the transparent film is judged to reach the same level of the aluminum-plated film, and the heat conductivity coefficient of the made vacuum heat insulation composite board is also consistent with that of the vacuum heat insulation board made of the aluminum-plated film.
d. Edge conduction testing of sheet materials
The experimental method comprises the following steps: the composite board and the vacuum insulation board with the size of 300MM × 300MM made of different film materials are placed on a heating table with the temperature of 40 ℃ to be heated for 30 minutes, and the edge heat transfer effect is checked through infrared imaging and temperature detection.
Referring to fig. 2-4, fig. 2 is a thermal image of a vacuum insulation panel including an aluminum foil film. Fig. 3 is a thermal imaging view of a vacuum insulation panel comprising an aluminum plated film. Fig. 4 is a thermal imaging diagram of the composite board of the present embodiment. The comparison shows that the composite board has obviously lower edge heat conduction effect and is superior to the heat conduction of the vacuum heat-insulating board made of the aluminum foil film and the aluminum-plated film, so that the composite board made of the transparent film has superior comprehensive heat-insulating performance.
e. Aging test of plate life
The test method comprises the following steps: referring to the standard GB37608-2018, the composite board and the vacuum composite board made of the aluminizer and the aluminum foil are placed in a high-temperature high-humidity box with the temperature of 70 ℃ and the humidity of 90% for life aging test, the heat conductivity coefficient is detected every 7 days, and the conclusion of the life test is judged according to the increase condition of the heat conductivity coefficient. The results are shown in Table 10.
Table 10: plate life aging test result table
Figure BDA0003187642710000101
The test shows that the performance of the composite board prepared by the embodiment is superior to that of the vacuum insulation board prepared by the aluminum-plated film when the composite board is subjected to an accelerated aging test under the humidity condition of 70-90%, but the composite board is inferior to that of the vacuum insulation board prepared by the aluminum foil film, so that the transparent film prepared by the embodiment has better high-temperature and high-humidity resistance than that of the aluminum-plated film product for the vacuum insulation board.
