Embodiment 1

[0040] Embodiment 1: see figure 1 , the glass-welded ceramic composite vacuum panel is composed of a panel 1, a connecting layer 2, a vacuum chamber 3 and a support 4, and the panel 1 is composed of a ceramic plate or ceramic tile or soft tile or mosaic with a thickness of 2-12 mm; the connecting layer 2 is High-temperature-resistant adhesives can be selected from high-temperature-resistant phenolic resin adhesives, epoxy resin adhesives, silicone resin adhesives, polyimide and other organic adhesives that can be cured at room temperature or high temperature, as well as commonly used inorganic adhesives or organic-inorganic composite adhesives; 3. It is welded by low-carbon steel plate with a thickness of 0.3-1.0mm; the support 4 is made of metal, ceramics, glass or polymer, and is distributed in a vacuum in a dot matrix by printing, printing, spraying, mechanical layout, etc. In the cavity 3, the supporting height of the support 4 is preferably 0.15-1.0 mm, and the diameter o...

Embodiment 2

[0041] Example 2: See Example 1 and figure 2 , basically the same as Example 1, except that the low-carbon steel plate forming the vacuum chamber 3 is directly punched out of the support 4 and sealing grooves for edge sealing during stamping, and glass solder is placed in the sealing grooves.

Abstract

The invention discloses a glass welded ceramic composite vacuum plate. The ceramic composite vacuum plate comprises a panel, a connecting layer and a vacuum cavity, and is characterized in that the panel is made from a ceramic plate or a ceramic tile, the panel and the vacuum cavity are integrally formed by the connecting layer, the panel and/or the connecting layer are used for providing additional strength to the vacuum cavity so as to ensure the smoothness of the vacuum cavity at barometric pressure, and the vacuum cavity is a closed cavity formed by carrying out glass welding and sealing at constant pressure and high temperature and sealing at high temperature in vacuum to low carbon steel plates; the coefficients of thermal expansion of the low carbon steel plate and the glass solder are matched, and a support is arranged in the vacuum cavity and is separately made or directly formed in the vacuum cavity. A production method of the ceramic composite vacuum plate provided by the invention is simple in process, the defects of an existing insulation board and an existing vacuum insulated panel can be overcome, the air-tightness of the stone composite vacuum plate can be effectively ensured, the service life of the ceramic composite vacuum plate can be prolonged, and the strength, heat insulation, sound insulation and fire resistance can be enhanced.

Description

technical field [0001] The invention relates to the technical field of building energy conservation, in particular to a glass-welded ceramic composite vacuum panel 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 insulation material...
