Low-temperature thermal insulation plate of refrigerator car and manufacturing method thereof

Abstract

The invention provides a low-temperature thermal insulation plate of a refrigerator car and a manufacturing method thereof. The thermal insulation plate comprises an outer thermal insulation layer, the inner side of the thermal insulation layer is connected with an outer cementing layer in a bonding mode, the inner side of the cementing layer is connected with a metal layer, the inner side of the metal layer is connected with an inner cementing layer, the inner side of the inner cementing layer is connected with the middle heat preservation layer of the thermal insulation plate, the whole thermal insulation plate is centered on the middle heat preservation layer, the two outer sides of the whole thermal insulation plate are symmetrically arranged, and the outermost layer of the thermal insulation plate is wrapped by a PVC cow leather layer. The thermal insulation plate has high low-temperature resistance, does not deform, expand, shrink or leak air at the temperature ranging from-30 DEG C to-40 DEG C, has certain impact resistance, can meet the strength requirement of a long-distance cold chain transport vehicle, and is suitable for being popularized and used in refrigerator cars.

Description

technical field [0001] The invention belongs to the technical field of cold chain transportation, and in particular relates to a low-temperature insulation panel for a refrigerated vehicle and a manufacturing method thereof. Background technique [0002] In the traditional cold chain logistics transportation, when the refrigerated truck transports items with temperature requirements such as the food and drug industry, one compartment can only store food or items with one temperature requirement. However, according to the needs of real life, in most The commercial, supermarket, and fresh vegetable and fruit markets at the end of the cold chain often need frozen, refrigerated, and normal-temperature items at the same time, and the quantities vary. It will be reduced, which is not conducive to the development of the transportation industry, nor can it meet the needs of cold chain terminals. Based on market demand, some traditional insulation panels have appeared on the market ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a low-temperature insulation panel for refrigerated vehicles, which can solve the problems of poor low-temperature resistance, easy breakage, and shrinkage and air leakage at low temperatures in existing refrigerated vehicle insulation panels. The problem and the short board of the existing refrigerated vehicle heat insulation board, the present invention proposes a kind of low temperature heat insulation board of refrigerated vehicle and its manufacturing method, and its technical scheme is:
