Embodiment 2

[0059] The difference between this embodiment and embodiment 1 is that the EPP material is replaced by EPS (polystyrene foam) material. Correspondingly, in step 6 of the production process, the temperature of the steam used for foaming the EPS particles is 90-110° C., and the steam pressure is 0.1 MPa-0.4 MPa. All the other parts are the same as in Embodiment 1, and the structure of the cold chain incubator is also the same as in Embodiment 1, so no further details are given.

[0060] further reference image 3 , the EPS and VIP integrally molded cold-chain incubator provided in this example has a size of 420mm*350mm*240mm, and the thickness of VIP is 10mm. The cold-chain incubator is placed in 6.15kg of cooling agent at an ambient temperature of 37°C. The change of the temperature in the center of the box is as follows: image 3 As shown, the time for maintaining the temperature in the center of the box below 8°C is 87.2 hours, and the time for maintaining the temperature i...

Abstract

The invention provides a production method for a cold chain thermal insulation box. After a VIP box of which the top end face is an open face is formed by spicing vips, a box inner mold is placed in the VIP box, and then the VIP box and the box inner mold are placed in a box outer mold; a gap space is formed between the outer wall of the VIP box and the inner wall of the box outer mold, and the box inner mold abuts against the inner wall of the VIP box; then a VIP serves as a VIP cover plate, the VIP cover plate is laid on a cover plate inner mold, and a cover plate outer mold is arranged on the VIP cover plate; a gap space is formed between the VIP cover plate and the cover plate outer mold similarly; EPP or EPS particles are injected into the gap spaces; and high-temperature high-pressure steam is led to the gap spaces, and foaming, adhering and forming of the EPP or EPS particles are completed. The production method is simple in process, the VIP box is formed integrally, machining cost is low, and the yield is high. The invention further provides the cold chain thermal insulation box small in overall weight, and protruding, adhesion failure, deformation and other problems are avoided.

Description

technical field [0001] The invention relates to the field of cold chain heat preservation, in particular to a cold chain heat preservation box and a manufacturing method of the cold chain heat preservation box. Background technique [0002] Vacuum insulation panel (VIP) is made by wrapping the core material and getter in the barrier bag and vacuumizing it. It effectively avoids the heat transfer caused by air convection, has the characteristics of high efficiency and energy saving, and is a superior high-efficiency thermal insulation material. The barrier bag is mainly a packaging bag composed of polymer film and special coating film or aluminum foil. It is a key component of VIP, and it plays a role in blocking air and water vapor from entering the bag to achieve the purpose of vacuum insulation. Therefore, it is necessary to carry out vacuum insulation panels Prepare a cold chain incubator for packaging protection. In order to solve the protection and use of VIP, people u...
