Heat preservation interlayer and heat preservation tool

Abstract

The invention discloses a heat preservation interlayer and a heat preservation tool, the heat preservation interlayer comprises a plurality of first heat insulation layers arranged at intervals, and the first heat insulation layers are made of aerogel materials; the first heat insulation layer is of a plane structure; each second heat insulation layer is arranged between every two adjacent first heat insulation layers; the second heat insulation layer is made of the aerogel material; and the second heat insulation layer is pressed into a three-dimensional pattern shape. According to the arrangement, the second heat insulation layers are pressed into the three-dimensional pattern shape to be arranged during manufacturing, so that the hollow part of the heat preservation interlayer can be increased, the heat preservation performance is improved, it is guaranteed that an enough cold insulation effect can be provided for fresh food during long-distance transportation and long-time selling, and it is guaranteed that the product quality is not changed; and heat insulation materials can be saved, and the requirement for strength is met.

Description

technical field [0001] The invention relates to the technical field of thermal insulation interlayers, in particular to a thermal insulation interlayer and a thermal insulation tool. Background technique [0002] At present, fresh food companies usually use cold chain logistics vehicles for long-distance transshipment of products. During the transshipment process, since fresh food customers often use cheap expanded polystyrene foam boxes when transshipping and storing products, the insulation of the foam boxes The time is short, and often can only meet the short-distance heat preservation needs of 2-3 hours. [0003] However, most of the production factories of fresh food companies are located in the core cities of the first and second tiers, which are far away from the third and fourth tier cities. Quality drops. Contents of the invention [0004] Therefore, the technical problem to be solved by the present invention lies in the problem that the long-distance transporta...

AI Technical Summary

Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention lies in the problem that the long-distance transportation and long-term sales in the prior art make the foam box insufficient for fresh food cold preservation, resulting in a decline in product quality, thereby providing a thermal insulation interlayer and insulation tool
