Abstract

A cold storage wall is characterized in that the cold storage wall comprises a matrix wall, polyurethane foam layers and vacuum insulation boards, wherein, vacuum insulation boards are inserted in the polyurethane foams of different thickness, and the vacuum insulation boards in each thickness layer are arranged in intervals; the thickness of the polyurethane foam layers is between 8mm and 25mm; material A of the polyurethane foam layer is isocyanate and material B is polyester polyol and auxiliary agent. The construction method of the wall comprises the steps of (1) spraying a polyurethane foam layer; (2) paving the vacuum insulation boards in intervals, and spraying a layer of polyurethane foam; (3) repeating step (1)-(2) to obtain a polyurethane foam layer wall that has the vacuum insulation boards inserted in. The beneficial effects of the present invention are that (1) the heat insulation effect is good; (2) the construction is convenient; and (3) the cold storage wall slit condensed water is prevented from icing and destroying the wall structure.

Description

technical field [0001] The invention relates to a refrigerator wall, in particular to a refrigerator wall and a construction method thereof. Background technique [0002] Large-scale cold storage has high requirements on the heat insulation effect of walls and floors. Ordinary materials used as cold storage walls have poor heat insulation effect. In the case of achieving the same heat insulation effect, the thickness required for various materials is compared as follows: ordinary Brick needs 860mm, concrete block needs 860mm, cork needs 140mm, fibreboard needs 65mm, light cork needs 50mm, mineral wool needs 45mm, polystyrene needs 40mm, polyurethane needs 25mm. Therefore, in order to achieve a better heat insulation effect, the thickness of the heat insulation material used is relatively large, which makes the amount of cold storage consumables too large, which virtually increases the construction cost. Therefore, it is particularly important to use lightweight materials as...
