Problems solved by technology

[0002] At present, the materials used in domestic building exterior wall insulation are mainly Class B insulation materials, such as polystyrene, polyurethane, foam rubber and other organic materials. These organic materials have poor heat resistance and are easy to burn. When burning, they not only release a lot of heat, A large amount of toxic smoke is produced, and it can accelerate the spread of the fire; at the same time, the organic material will shrink during the fire, resulting in burning droplets, causing the tiles on the insulation layer to fall off, which is likely to cause secondary fires and secondary fires. Second damage, so the relevant part of the country expressly prohibits the use of organic thermal insulation materials for external wall insulation, especially in high-rise buildings and public buildings
Among the thermal insulati...

preparation example Construction

[0124] The present invention also provides a method of manufacturing a convex vacuum insulation panel with a vacuum layer, comprising:

[0125] The first step, the preparation of the mold: according to the shape and size of the convex vacuum insulation panel to be produced, the production mold of the convex insulation panel is prepared;

[0126] When the heat insulation board is a glass plate, make the hot bending mold in the existing hot bending glass preparation technology;

[0127] When the heat insulation board is a ceramic board, the stamping die or grouting die in the existing ceramic board preparation technology is made;

[0128] When the heat insulation board is a metal plate, the stamping die in the existing metal plate preparation technology is made;

[0129] The second step, the production of the convex heat insulation board: use the mold to prepare the convex heat insulation board;

[0130] When the heat insulation board is a glass plate, prepare a flat glass pla...

Embodiment 1

[0234] Embodiment 1: see figure 1 , the vacuum insulation panel is composed of an upper convex glass insulation panel 1 and a lower convex glass insulation panel 2, the periphery of the two insulation panels is welded together by low-temperature glass solder 3, and the middle is a vacuum layer. The production method is as follows: first, prepare two pieces of flat glass of the required size according to the shape and size of the vacuum insulation panel to be produced, and perform edge grinding, chamfering, cleaning and drying; secondly, put the two glass plates into the mold, place In the hot bending furnace, the temperature is raised to 550-750°C, which is the softening temperature of the glass, and the glass plate is formed into a convex surface by the gravity of the glass itself, and the glass plate is lowered to room temperature with the furnace; Coat the low-temperature glass solder, leave several air holes evenly on the low-temperature glass solder, align and stack the t...

Embodiment 2

[0235] Example 2: see figure 1, the vacuum heat insulation board is composed of an upper convex ceramic heat insulation board 1 and a lower convex ceramic heat insulation board 2, the periphery of the two heat insulation boards is welded together by a high-temperature ceramic glaze 3, and the middle is a vacuum layer. The production method is as follows: firstly, a metal stamping mold is prepared according to the shape and size of the vacuum insulation panel to be produced; secondly, the raw materials for making the ceramic insulation panel are loaded into the mold, and pressurized and formed by a press, and the mold is opened to obtain a ceramic insulation panel. The body of the plate is dried in a dryer; again, the two sides or one side of the body of the two ceramic plates and the periphery of the welding surface are evenly coated with high-temperature ceramic glaze, and several glazes are evenly left on the peripheral glaze on the welding surface. Air extraction holes, and...
