Heat-insulating layered material

Abstract

The invention discloses a heat-insulating layered material. The layered material sequentially comprises a metal foil layer, a high-density polyurethane foam layer, a toughening layer, a tackifying layer and a water blocking layer, the metal foil layer and one side, in contact with the metal foil layer, of the high-density polyurethane foam layer are uniformly provided with waveform structures, every waveform structure has peaks and troughs, a vertical distance between one of the peaks and the nearest trough is H, a distance between the adjacent peaks is L, the L is more than 2H, and the H is 0.5-1 mm. The layered material obtained in the invention has the advantages of excellent heat insulating property, excellent mechanical strength and low weight, and is suitable for making high temperature incubators or a low temperature incubators.

Description

technical field [0001] The present invention relates to the field of layered materials, in particular to the field of insulating layered materials with excellent thermal insulation, mechanical strength and low quality. Background technique [0002] With the rapid development of "Internet +" and the rapid development of food delivery and other industries, full-time food delivery delivery personnel have become an emerging industry, and all food delivery companies have established delivery teams. In order to ensure fast and high-quality delivery of food, food incubators have become necessary equipment. The incubators used in the prior art have more or less problems, and it is difficult to meet the comprehensive performance requirements of food incubators. [0003] The problems existing in the prior art mainly focus on: ① Insufficient heat preservation effect; ② Insufficient strength of the incubator; ③ Excessive mass of the incubator. The above three problems appear to be cont...

AI Technical Summary

Problems solved by technology

In order to ensure the fast and high-quality delivery of food, food incubators have become necessary equipment. The incubators used in the prior art have more or less problems, and it is difficult to meet the comprehensive performance requirements of food incubators.

[0003] The problems existing in the prior art mainly focus on: ① Insufficient heat preservation effect; ② Insufficient strength of the incubator; ③ Excessive mass of the incubator

The above three problems appear to be mutually contradictory, it is difficult to take into account the performance of the three, and there is a big trouble for users

The above-mentioned problems are mainly caused by the layered materials for the preparation of incubators, and due to the low starting point in this field, no relevant systematic research has been reported yet.
