Problems solved by technology

[0002] Existing thermal insulation materials for packaging are mainly pearl cotton composite aluminum film and bubble cotton composite aluminum film. The material is a multi-layer structure bonded and compounded by glue. Limited by the distance, each layer of material relies on its own performance to achieve heat insulation. The heat insulation effect after compounding is the superposition of the effects of each layer, and the composite performance cannot be truly realized.

Abstract

The present invention discloses a thermal insulation plate, which comprises an aluminum film layer, a foaming layer and a separation layer, wherein the aluminum film layer is positioned on the inner layer of the thermal insulation plate, the separation layer is positioned on the outer layer of the thermal insulation plate, and the foaming layer is positioned between the aluminum film layer and the separation layer. The thermal insulation plate of the present invention has good thermal insulation effect.

Description

technical field [0001] The invention relates to the technical field of heat insulation, in particular to a thermal insulation board. Background technique [0002] Existing thermal insulation materials for packaging are mainly pearl cotton composite aluminum film and bubble cotton composite aluminum film. The material is made of multi-layer structure through glue bonding. Limited by the distance, each layer of material relies on its own performance to achieve heat insulation. The heat insulation effect after compounding is the superposition of the effects of each layer, and the composite performance cannot be truly realized. Contents of the invention [0003] In order to solve the problems in the prior art, the object of the present invention is to provide a thermal insulation board. The thermal insulation board of the present invention has good heat insulation effect. [0004] In order to achieve the above object, the technical solution adopted by the present invention is...
