Embodiment 1
[0033] A multifunctional composite vacuum insulation panel of the present invention, please refer to figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 As shown, it includes a single-layer vacuum insulation panel, a thermal insulation composite layer 2 and a protective layer 3. The single-layer vacuum insulation panel includes a core material 1 and a first polyester-based film 11. The core material 1 is made of glass fiber, and the core material 1 is set In the first polyester-based film 11 and vacuumized and edge-sealed to form a single-layer vacuum insulation panel, the thermal conductivity of glass fiber is low, and the thermal insulation performance is good; the thermal insulation composite layer 2 is wrapped on the outside of the single-layer vacuum insulation panel, and the single-layer vacuum insulation panel The vacuum insulation panel is sealed inside the thermal insulation composite layer 2. The thermal insulation composite layer 2 includes three layers of ...
Embodiment 2
[0043] This embodiment provides a method for manufacturing and packaging a multifunctional composite vacuum insulation panel, wherein the method for manufacturing and packaging includes the following steps:
[0044] S1: To make a single-layer vacuum insulation panel, vacuumize the core material 1 and place it in an oven to preheat for 30 minutes at a temperature of 100-125°C to remove residual moisture inside the core material 1. Put the core material 1 into the first polyester base The film 11 is placed in a vacuum chamber to evacuate, heat-sealed and cut the excess lip of the first polyester-based film 11, heat-sealed and folded, and bonded with an adhesive to form a single-layer vacuum insulation panel;
[0045] S2: The glass fiber layer 22 is preheated in the oven for 30 minutes at a temperature of 100-125°C, and the inorganic adhesive is applied on the single-layer vacuum insulation panel, and the preheated glass fiber layer 22 is evenly spread on the six surfaces of the s...
