Embodiment 1

[0066] A thermal insulation panel, comprising: a vacuum insulation panel and a foam material completely covering the vacuum insulation panel.

[0067] like figure 1 , the production method of the above-mentioned thermal insulation panel, which includes: horizontally arranging the vacuum insulation panel 3 in the first cavity 1, and setting the small blocks 2 prefabricated with foaming materials on the bottom of the surroundings of the vacuum insulation panel 3, and making the vacuum insulation The bottom and surroundings of the plate 3 have gaps with respect to each inner wall of the first cavity; then pour light polymer and foaming agent into the first cavity 1, and seal the opening of the first cavity Cover the top cover so that the generated foam material completely covers the vacuum insulation panel; open the top cover after molding, and take out the heat insulation panel.

Embodiment 2

[0069] On the basis of Embodiment 1, there are the following modifications in this embodiment:

[0070] like figure 2 , the production method of the heat insulation board, which includes: vertically setting the vacuum heat insulation board 3 in the second cavity 10, and setting the small block 2 prefabricated with foaming material (generally adopting bonding and fixing, for example, using double-sided Tape paper or glue) on the bottom and surrounding side walls of the vacuum insulation panel, so that there are gaps at the bottom and surrounding of the vacuum insulation panel 3; then pour light polymer and foam into the second cavity 10 agent, and cover the top opening of the second cavity 10 so that the generated foam material completely covers the vacuum insulation panel; after molding, open the top cover and take out the insulation panel.

Embodiment 3

[0072] On the basis of Embodiment 1, there are the following modifications in this embodiment:

[0073] like image 3 , the production method of the thermal insulation board, it comprises: adopt bendable vacuum heat insulation board 3 to fold into the hollow cylinder that the cross section is the shape of a square; In the third cavity 101 of the vacuum insulation panel 3, the small blocks 2 prefabricated with foaming materials are arranged on the inner, outer sides and bottom of the vacuum insulation panel 3, so that the inner, outer sides and bottom of the vacuum insulation panel 3 are in contact with the third cavity 101 There are gaps in the inner walls of the third cavity; then pour light polymer and foaming agent into the third cavity, and cover the opening of the third cavity with a top cover, so that the generated foam material can completely cover the cavity. Cover the vacuum insulation board; open the top cover after forming, and take out the integrated heat insulati...

Abstract

The invention provides a heat insulation board, a production method of a heat insulation board, a cold storage box, and a heat insulation board, which are characterized in that they include: a vacuum heat insulation board and a foam material completely covering the vacuum heat insulation board. The cold storage box includes a box cover and a box body, and the box cover and the box body include the heat insulation layer; in the present invention, the foam material and the vacuum insulation board are formed into one body, and respectively constitute the insulation of the box cover and the box body. thermal layer. Furthermore, the vacuum insulation panel is completely covered by the foam material, so the wear resistance and impact resistance of the VIP can be greatly improved, and the VIP is not easily damaged. Furthermore, on the cold storage box, the thermal insulation advantage of VIP can be fully utilized to greatly improve the cold storage effect.

Description

technical field [0001] The invention relates to a heat insulation board, a production method of the heat insulation board and a cold storage box. Background technique [0002] Chinese patent document CN2035740U discloses a portable cold storage box, which is composed of a box cover and a box body. There is a heat insulation layer made of expanded polystyrene in the box cover and the box body. When the box body and the box cover are inflated or compressed After the structure is closed, keep the box in a low temperature state for a long time. [0003] Polystyrene foam (Expanded Polystyrene referred to as EPS) is a light polymer. It is made by adding foaming agent to polystyrene resin and softening by heating at the same time. The foaming agent generates gas to form a foam with a rigid closed-cell structure. Its processing method can be divided into pattern method and extrusion method according to the different foaming methods. The thermal conductivity of polystyrene is 0.11...
