Embodiment Construction

[0019] see figure 1 , with reference to figure 2 , image 3 , the inverted U-shaped thermal insulation board for liquefied gas cryogenic storage tanks with bending properties of the present invention, comprising an elastic foam layer 1, a mixed foam layer 2, a glass fiber cloth layer 3, and a foam layer 4 arranged sequentially from outside to inside and protection layer 5. The layers are bonded with elastic glue or thermoplastic glue, or directly through heat welding.

[0020] The inverted U-shaped insulation board of the present invention is arranged in a stepped shape in the axial direction, that is, the mixed foam plastic layer forms a first step 6 relative to the elastic foam plastic layer, and the glass fiber cloth layer, the foam plastic layer and the protective layer are combined into a whole relative to the mixed foam plastic layer. The foam layer forms the second step 7 .

[0021] The mixed foam plastic layer 2 is composed of three sections of material in the rad...

Abstract

The invention discloses an inverted-U-shaped heat insulation board having the bending characteristic and used for a liquefied gas low-temperature storing tank. The inverted-U-shaped heat insulation board comprises an elastic foamed plastic layer, a mixed foamed plastic layer, a glass fiber cloth layer, a foamed plastic layer and a protection layer, all of which are sequentially arranged from outside to inside. All the layers are arranged in a step shape in the axial direction, in other words, the mixed foamed plastic layer forms a first step relative to the elastic foamed plastic layer, and the glass fiber cloth layer, the foamed plastic layer and the protection layer are combined into a whole to form a second step relative to the mixed foamed plastic layer. The heat insulation board is used for being installed in a specified area of the storage tank, and due to tight cooperation among all heat insulation boards, an airtight heat insulation layer is formed in the specified area of the storage tank. In addition, the inverted-U-shaped heat insulation board has the beneficial effects of being convenient to install, excellent in performance and efficient in production.

Description

technical field [0001] The invention relates to a thermal insulation material, in particular to an inverted U-shaped thermal insulation board for liquefied gas cryogenic storage tanks with bending properties. Background technique [0002] The liquefied gas storage tank has a certain demand for the insulation board with bending characteristics. The insulation boards in the prior art have the following problems: (1) the degree of bending is limited and cannot fully meet the needs of the market; (2) it is easy to break after bending; (3) the assembly structure is not tight; (4) the insulation board and the storage tank connection is not secure. Limited by the characteristics of raw materials, the application of such insulation boards with bending characteristics is limited. Contents of the invention [0003] The object of the present invention is to provide an inverted U-shaped insulation board for liquefied gas cryogenic storage tanks with bending properties in order to ov...
