Problems solved by technology

[0005] However, the thermal insulation core material silica airgel in this technology is brittle, and the strength of the panel after processing into a vacuum insulation panel is poor, and it can be broken by a small external force. Therefore, in the process of transportation and processing into electrical appliances or equipment can destroy its original structure

Abstract

The invention discloses a high-strength vacuum heat insulation plate, comprising a vacuum shell bag and a heat insulation core material which is arranged in the vacuum shell bag. The heat insulation core material comprises a middle heat insulation layer. Two sides of the middle heat insulation layer are provided with a plate with a plurality of hemispherical depressions; one side of the plate in the trailing direction of the middle heat insulation layer is provided with an infrared reflection layer; the hemispherical depressions of the plate are filled with silica aerogel. The high-strength vacuum heat insulation plate of the invention has high strength, low thermal conductivity and good high temperature resistance.

Description

technical field [0001] The invention relates to a thermal insulation material, in particular to a vacuum heat insulation panel. Background technique [0002] Traditional thermal insulation boards use glass fiber, glass surface, foamed polyurethane, and expanded styrene. The above-mentioned thermal insulation boards have low thermal conductivity and good thermal insulation performance, but they are used in specific industries such as electrical appliances such as refrigerators and electric water heaters to keep cold Or heating equipment, etc., often require a larger thickness, the increase in thickness will lead to a larger volume of electrical appliances, and the effective use of space will be reduced. [0003] Based on the above reasons, a vacuum insulation panel is proposed. The vacuum insulation panel can greatly reduce the thermal conductivity of the existing insulation panel, usually more than 5 times. Therefore, under the same requirements for electrical insulation, th...
