Problems solved by technology

Although the thermal insulation performance of polyurethane foam is relatively good, in order to achieve the required preservation effect, the thickness of polyurethane foam in the refrigerator box is generally about 50mm, resulting in a relatively thick cold storage box
In order to maintain the effective volume inside the box, the overall size of the box needs to be made larger, so it is not practical

Embodiment 1

[0016] The hard polyurethane layer is composed of 23.5-25.0wt% MDI, 18.0-20.0wt% PEG1000, 5.0-5.5wt% PTMG1000, 2.0-2.2wt% 1,4-butanediol, 1.2-1.5wt% % of ethoxylated bisphenol F diacrylate, 1.5~1.8wt% of vinyltriethoxysilane, 0.20~0.25wt% of dibutyltin dilaurate, 5.0~5.5wt% of ethyl methyl carbonate and the balance The ethyl acetate is used to prepare the polyurethane prepolymer, which is then cast or coated. Specifically, at room temperature, stir the raw materials of the above ratio except dibutyltin dilaurate evenly, then adjust the temperature of the reaction solution to 83-85°C under a nitrogen atmosphere, and then add the ratio of dilaurate Acetate dibutyltin, react for 100-120 minutes, and after cooling, a polyurethane prepolymer can be obtained; then a hard polyurethane layer can be obtained by known casting or coating methods. The hard polyurethane layer has excellent mechanical properties. When the thickness of the hard polyurethane layer is 0.1mm, its tensile stren...

Embodiment 2

[0025] The vacuum insulation panel includes a core material and a sealing layer, the core material is a board formed of glass fiber and an air-absorbing composition, and the inside thereof maintains a vacuum; the sealing layer seals the core material, and the sealing layer The layer is formed by the first aluminum foil layer and the second aluminum foil layer laminated on the upper surface and the lower surface of the PET film layer; the thickness of the PET film layer is 100-120 μm, and the thickness of the first aluminum foil layer and the second aluminum foil layer is Both are 20-25 μm; and the first aluminum foil layer and the second aluminum foil layer are anodized to form an anodized aluminum film. The preparation method of described anodized aluminum film is as follows: first, aluminum foil layer is cleaned (with acid cleaning agent AcidClean UC, product of Atotech Co., Ltd. of Germany) for cleaning, and then immersing in 30°C, 5wt% sodium hydroxide aqueous solution fo...

Abstract

The invention discloses a heat insulation cold closet. According to the heat insulation cold closet, due to the fact that a vacuum heat insulation panel layer and a rigid polyurethane layer are arranged in a polyurethane foamed plastic layer to form a composite head insulation structure, the thickness of the heat insulation cold closet is reduced so that the effective volume of a heat insulation closet in the same shape can be greatly increased; furthermore, the coefficient of heat insulation of the heat insulation cold closet is smaller than or equal to 0.004W / mK, heat radiation, heat conduction and heat convection between the interior of the closet body and the outside environment can be effectively prevented, and the heat insulation closet can guarantee that the interior temperature is controlled below 2-8 DEG C for more than 120 hours. The heat insulation cold closet is mainly used for cold storage and refrigeration during transportation and storage of medicine such as vaccine, insulin, blood products, biological products and reagents.

Description

technical field [0001] The invention relates to the technical field of medical medicine preservation, and more specifically, the invention relates to an insulated refrigerator for medical medicine. Background technique [0002] With the rapid development of bioengineering technology, biological drugs targeting major diseases and difficult-to-treat diseases are constantly appearing. When the temperature of the external environment is too high for these drugs, the chemical reaction will be accelerated, and microorganisms will easily breed, thereby destroying the structure of the drug, causing the drug to deteriorate and not achieve good efficacy. side effects, and even death, so biological drugs should be kept in a low temperature environment during the development, storage, transportation and many other links. [0003] The cold storage of medicines is mainly divided into active cold storage and passive cold storage. Active refrigeration needs to be connected to the power su...
