A composite hollow insulation box inner plate

Abstract

The invention discloses a composite hollow heat-insulated box internal board. The composite hollow heat-insulated box internal board comprises a hard-plastic substrate, a second hollow heat-insulatedplate, a second heat-proof connecting film, a first hollow heat-insulated plate, a first heat-proof connecting film and an alloy aluminum foil layer are orderly tiled, adhered and fixed on the hard plastic substrate through adhesive layers; the first hollow heat-insulated plate and the second hollow heat-insulated plate are same in the structure and overall specification; a vacuum layer is arranged in each of the first hollow heat-insulated plate and the second hollow heat-insulated plate, and the height of the hollow layer in the first hollow heat-insulated plate is greater than the height ofthe vacuum layer in the second hollow heat-insulated plate, the structures of the first heat-proof connecting film and the second heat-proof connecting film are same, and the thickness of the first heat-proof connecting film is greater than the thickness of the second heat-proof connecting film.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to an inner plate of a composite hollow thermal insulation box. Background technique [0002] With the improvement of living standards and the rapid development of the catering industry, food delivery is a new profit growth point in the catering industry. Enjoying all kinds of delicacies at home and family has become a healthy and natural way of life, which is more common in foreign developed countries. It is also becoming more and more popular in the country. The incubator has attracted the attention of the catering industry with the concept of safety and environmental protection, cold and heat preservation, and easy portability; the incubator is divided into different types according to the product texture, including plastic, foam, metal, wooden and other incubators. . [0003] In order to reduce the weight of the traditional incubator, the foam board materi...

AI Technical Summary

Problems solved by technology

[0003] In order to reduce the weight of the traditional incubator, the foam board material is often used to make the incubator. Although its weight is light, its insulation effect and structural stability are poor. When juice enters the interior of the incubator, its cleanability is poor. Poor, easy to breed bacteria; lead to low reuse rate of the entire incubator, which is a waste of resources, so it needs to be improved urgently
