Embodiment 1
[0017] In this embodiment, the shell layer and the shell layer are both made of carbon steel, and the thickness of the shell layer and the shell layer is 2-20 mm; the thickness of the vacuum insulation panel layer is 10 mm, and the first hard The thickness of the first rigid polyurethane foam is 25mm, and the thickness of the second rigid polyurethane foam is 25mm. And, the first rigid polyurethane foam and the second rigid polyurethane foam are made of 22.0wt% carbodiimide modified MDI, 18.0wt% PEA-1000, 7.5wt% PEBA-1000, 2.5 wt% of hydroxyl-terminated polybutadiene, 3.0wt% of polyvinylamine resin (molecular weight is 800), 1.6wt% of polydimethylsiloxane, 0.20wt% of triethylenediamine, 12.0wt% of The composition of cyclopentane, 1.2wt% of water and the rest of ethyl acetate is uniformly mixed and poured.
Embodiment 2
[0019] In this embodiment, the shell layer and the shell layer are both made of carbon steel, and the thickness of the shell layer and the shell layer is 2-20 mm; the thickness of the vacuum insulation panel layer is 10 mm, and the first hard The thickness of the first rigid polyurethane foam is 25mm, and the thickness of the second rigid polyurethane foam is 25mm. And, the first rigid polyurethane foam and the second rigid polyurethane foam are made of 22.0wt% carbodiimide modified MDI, 18.0wt% PEA-1000, 7.5wt% PEBA-1000, 2.0 wt% of hydroxyl-terminated polybutadiene, 3.0wt% of polyvinylamine resin, 1.6wt% of polydimethylsiloxane, 0.20wt% of triethylenediamine, 12.0wt% of cyclopentane, 1.2 It is obtained by uniformly mixing the composition of wt% water and the balance of ethyl acetate and pouring.
Embodiment 3
[0021] In this embodiment, the shell layer and the shell layer are both made of carbon steel, and the thickness of the shell layer and the shell layer is 2-20 mm; the thickness of the vacuum insulation panel layer is 10 mm, and the first hard The thickness of the first rigid polyurethane foam is 25mm, and the thickness of the second rigid polyurethane foam is 25mm. And, the first rigid polyurethane foam and the second rigid polyurethane foam are made of 22.0wt% carbodiimide modified MDI, 18.0wt% PEA-1000, 7.5wt% PEBA-1000, 2.5 wt% of hydroxyl-terminated polybutadiene, 3.0wt% of polyvinylamine resin, 1.6wt% of polydimethylsiloxane, 0.20wt% of triethylenediamine, 12.0wt% of cyclopentane, 0.8 It is obtained by uniformly mixing the composition of wt% water and the balance of ethyl acetate and pouring.
