Problems solved by technology

[0004] Existing thermal insulation materials cannot be used alone as external walls, and the thermal insulation performance of existing external walls is very poor. If the thermal insulation board is directly used on the external wall and the external wall insulation is omitted, it will not only save time, labor, materials, and service life Long, and easy to realize industrialized production of construction

Embodiment 1

[0064] Embodiment 1: see figure 1 , a low-temperature glass-sealed convex vacuum glass insulation panel. The vacuum glass insulation panel is composed of an upper convex glass 1 and a lower convex glass 2. The peripheries of the two pieces of glass are welded together by the first sealing 3 low-temperature glass solder, and the middle is a vacuum layer. The production method is as follows: first, cut two pieces of flat glass of required size according to the shape and size of the vacuum glass insulation panel to be produced, and perform edge grinding, chamfering, cleaning and drying; secondly, put the two pieces of glass into the mold and place In the hot bending furnace, heat up to the softening temperature of the glass at 550-750°C, rely on the gravity of the glass to make the glass downward to form a convex surface, and then drop to room temperature with the furnace; again, coat the periphery of two pieces of glass or one piece of glass evenly Coat the low-temperature glas...

Embodiment 2

[0066] Example 2: see figure 1 , an adhesive-sealed convex vacuum glass insulation panel. The vacuum glass insulation panel is composed of an upper convex glass 1 and a lower convex glass 2. The periphery of the two glasses is sealed together by the first sealing 3 adhesive, and the middle is a vacuum layer. Its production method is basically the same as that of Example 1, except that the glass solder is replaced by silicone adhesive, and the sealing temperature is lowered by 100°C.

[0067] The innovative point of the present invention is that a layer of metal film is formed on the surface of the silicone adhesive by vacuum coating, thereby greatly improving the airtightness of the silicone adhesive and making the sealing of the silicone adhesive possible.

Embodiment 3

[0068] Embodiment 3: see figure 1 , a metal-sealed convex vacuum glass insulation panel, the vacuum glass insulation panel is composed of an upper convex glass 1 and a lower convex glass 2, the periphery of the two glasses is sealed together by the first sealing 3 metal tin alloy, and the middle is a vacuum layer. The manufacturing method is basically the same as that of Example 1, except that the glass solder is replaced by tin alloy, and the sealing temperature is lowered by 160°C.

[0069] The innovation of the present invention lies in: using a tin alloy with a lower sealing temperature and vapor pressure to seal the vacuum layer can not only lower the sealing temperature, save energy and time, but also prevent a large amount of volatilization and loss of metal solder and pollute the edge sealing furnace and vacuum pump.

Abstract

The invention relates to a vacuum-glass heat-insulating board. The vacuum-glass heat-insulating board comprises upper glass and lower glass, wherein the periphery of the upper glass and the periphery of the lower glass are connected together through a sealing material in a sealing manner, a closed vacuum layer is formed between the upper glass and the lower glass and contains a low-melting-point or volatile or highly-inspiratory metal, the upper glass and the lower glass are convex glass or flat glass, and the convex surface of the convex glass faces to the outer side. A manufacturing method for the vacuum-glass heat-insulating board disclosed by the invention is simple in process, the sealing effect is good, the air tightness and service life of the vacuum-glass heat-insulating board can be effectively guaranteed, and mechanized, automated and large-scale production can be achieved.

Description

technical field [0001] The invention relates to the technical field of glass deep processing, in particular to a vacuum glass insulation panel and a manufacturing method thereof. Background technique [0002] my country's energy resources are relatively short, and long-term energy supply is facing severe challenges. How to solve the problem of energy resources is related to the overall economic and social development of our country. With the acceleration of the urbanization process, building energy consumption is getting higher and higher. my country's building energy consumption has accounted for more than 1 / 3 of the energy consumption of the whole society, and it is increasing year by year. The use of thermal insulation building materials is the main way to reduce building energy consumption. One of the means. At present, many materials used for building exterior wall insulation are Class B insulation materials, such as polystyrene, polyurethane, foam rubber and other or...
