Problems solved by technology

[0003] The patent applicant disclosed a series of vacuum panels and their production methods in July 2013, although they solved the problems of fire prevention, heat preservation and service life of existing thermal insulation materials However, since the metal plates are directly welded together, there are obvious cold bridges at the edges, making the thermal insulation performance not optimal

Embodiment Construction

[0035] The implementation of the present invention will be described in detail below with examples and accompanying drawings, so as to fully understand and implement the process of how to apply technical means to solve technical problems and achieve technical effects in the present invention.

[0036] Referring to the accompanying drawings, the metal vacuum insulation panel with sealing strips and installation holes is composed of an outer shell 1, a core material 2, an air outlet and an installation hole 3, the outer shell 1 is composed of a low-carbon steel plate with a thickness of 0.3-1.0mm; the core material 2 is Glass fiber, pearl sand, perlite, vermiculite, airgel, etc., the core material 1 is preferably dried, packed in plastic bags, pre-vacuumized, etc.; the air outlet 3 is directly punched out of the upper low-carbon steel plate of the shell It consists of a suction nozzle and a groove on the lower low-carbon steel plate. Low-temperature solder 4 such as tin, zinc, ma...

Abstract

A metal vacuum insulation panel with sealing strips and mounting holes comprises a housing, a core material and a vacuum chamber and is characterized in that the mounting holes are combined with pumping holes and penetrate through the whole composite plate, the housing is a low-carbon steel plate, the core material is arranged in the vacuum chamber to provide the housing with additional strength, the vacuum chamber is a closed chamber formed by the housing subjected to glass soldering edge sealing at atmospheric pressure and high temperature and high-temperature opening sealing in vacuum, welding portions of the edge of the low-carbon steel plate are provided with the sealing strips, the coefficient of thermal expansion of the low-carbon steel plate is matched with that of glass solder, the opening sealing is the automatic sealing of the pumping holes preformed in the housing with low-temperature solder in a vacuum furnace according to the principle of liquid seal, and the low-temperature solder comprises low-temperature metal and alloy solder. A manufacturing method of the metal vacuum insulation panel with the sealing strips and the mounting holes is simple in process. The manufactured metal vacuum insulation panel with the mounting holes can overcome the deficiencies of existing insulation boards and vacuum insulation panels and the strength, thermal insulation, sound insulation and fireproof performance and decorative functions can be improved.

Description

technical field [0001] The invention relates to a vacuum heat insulation panel, in particular to a metal vacuum heat insulation panel with a sealing strip and a mounting hole and a manufacturing method thereof. Background technique [0002] At present, the materials used for building exterior wall insulation are divided into A-grade thermal insulation materials and B-grade thermal insulation materials. A-grade thermal insulation materials have good fire resistance, but their thermal insulation performance and water resistance are lower than B-grade thermal insulation materials, and there are high prices. Complex construction technology and other issues; B-grade thermal insulation materials have the advantages of low cost, good thermal insulation performance, and mature construction technology, but their durability is not good, heat resistance is poor, and they are easy to burn. Moreover, it can accelerate the spread of fire, so it is forbidden to use organic thermal insulati...
