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 insulation

preparation example Construction

[0133] The present invention also provides a method for preparing a convex low-altitude heat insulation board with a low-altitude layer, which includes:

[0134] The first step, the preparation of the mold: prepare the production mold of the convex heat insulation board according to the shape and size of the convex low-altitude heat insulation board to be made;

[0135] When the heat insulation board is a glass plate, make the hot bending mold in the existing hot bending glass preparation technology;

[0136] When the heat insulation board is a ceramic board, the stamping die or grouting die in the existing ceramic board preparation technology is made;

[0137] When the heat insulation board is a metal plate, the stamping die in the existing metal plate preparation technology is made;

[0138] The second step, the production of the convex heat insulation board: use the mold to prepare the convex heat insulation board;

[0139] When the heat insulation board is a glass plate,...

Embodiment 1

[0238] Example 1: see figure 1, The low-altitude heat insulation board is composed of an upper convex glass heat insulation board 1 and a lower convex glass heat insulation board 2. The peripheries of the two heat insulation boards are welded together by low-temperature glass solder 3, and the middle is a low-altitude 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 low-altitude heat insulation board 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-tempe...

Embodiment 2

[0239] Example 2: see figure 1 The low-altitude 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 high-temperature ceramic glaze 3, and the middle is a low-altitude layer. The production method is as follows: first, a metal stamping die is prepared according to the shape and size of the low-altitude heat insulation board; secondly, the raw materials for making the ceramic heat insulation board are loaded into the mold, and pressurized and formed by a press, and the mold is opened to obtain a ceramic heat insulation board. 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. Vent holes, a...

Abstract

The invention provides a low-altitude heat-insulating board which comprises an upper heat-insulating board and a lower heat-insulating board, wherein the peripheries of the upper heat-insulating board and the lower heat-insulating board are welded together through using a welding flux, a closed low-altitude layer is formed between the upper heat-insulating board and the lower heat-insulating board, the upper heat-insulating board and the lower heat-insulating board are flattened heat-insulating boards or convex-sided heat-insulating boards, and the convex side of each convex-sided heat-insulating board faces outwards. The production method of the low-altitude heat-insulating board provided by the invention is simple in process, and the prepared low-altitude heat-insulating board overcomes the defects of the existing heat-insulating board, so that the tightness of a low-altitude layer of the low-altitude heat-insulating board can be effectively guaranteed, the service life of the low-altitude heat-insulating board is prolonged, and the strength and heat insulation, sound insulation and fire prevention properties of the low-altitude heat-insulating board can be increased.
