Embodiment 1

[0026] refer to figure 1 , a thermal insulation board 1, comprising: a vacuum insulation board 1 and a high-resilience polyurethane foam 2 covering it; the high-resilience polyurethane foam 2 is coated on the upper and lower surfaces of the vacuum insulation board 1, and The surrounding sides of the heat insulation board 1; the density of the high resilience polyurethane foam 2 is ≥30kg / m 3 ;

[0027] The coating thickness of the high-resilience polyurethane foam 2 on the upper and lower surfaces of the vacuum insulation panel is ≤20 mm, and the coating thickness of the surrounding sides is ≤10 mm.

[0028] Because the high-resilience polyurethane foam 2 has the characteristics that it can undergo certain deformation when subjected to external force load, and quickly restores its original shape and size after losing the external force load. Therefore, it can provide the vacuum insulation panel 1 with sufficient anti-vibration, cushioning and compression resistance, effective...

Embodiment 2

[0038] The difference between this embodiment and Embodiment 1 is that: the side of the insulation board 1 close to the inner wall of the outer box is not coated with the high resilience polyurethane foam 2; the side farther away from the inner wall of the outer box is covered with the high resilience polyurethane foam 2 . like Figure 3-4 .

Abstract

The invention provides a heat preservation board. The heat preservation board comprises a vacuum insulation board and high-resilience polyurethane foam wrapped around the vacuum insulation board; thehigh-resilience polyurethane foam is wrapped around the upper surface and / or the lower surface of the vacuum insulation board and the peripheral side surfaces of the vacuum insulation board; the density of the high-resilience polyurethane foam is more than or equal to 30 kg / m<3>; and the wrapping thickness of the high-resilience polyurethane foam on the upper surface or the lower surface of the vacuum insulation board is less than or equal to 20 mm, and the wrapping thickness on the peripheral side surfaces is less than or equal to 10 mm. According to the heat preservation board, protection isprovided for the surface of the vacuum insulation board, and meanwhile, the high-resilience foam also plays a good sealing role when a cold chain heat preservation box is structured and manufactured,so that the excellent heat preservation performance of the vacuum insulation board can be maximally utilized; and in addition, the production process can be simple, materials can be saved, the working time can be saved, and the production cost can be reduced.

Description

technical field [0001] The invention relates to a thermal insulation material, in particular to a thermal insulation board and a thermal insulation storage box made of it. Background technique [0002] Due to the limitation of materials and production process of vacuum insulation panels, the three-dimensional geometric dimensions of the produced vacuum insulation panels are very irregular. In particular, the sides of the vacuum insulation panels have large size differences due to edge sealing or folding; in addition, the vacuum insulation panels only use about 0.1mm aluminized film for vacuum packaging, and it is easy to cause vacuum bags (vacuum bags) Formed by aluminized film) damage caused by thermal insulation damage. Therefore, it is difficult to directly use the vacuum insulation panel to make the incubator, but it is necessary to make a protective surface material outside the vacuum insulation panel to make the surface and surroundings smooth and standardized, and th...
