Abstract

The invention provides a vacuum 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 vacuum 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 vacuum heat-insulating board provided by the invention is simple in process, and the prepared vacuum heat-insulating board overcomes the defects of the existing heat-insulating board, so that the tightness of a vacuum layer of the vacuum heat-insulating board can be effectively guaranteed, the service life of the vacuum heat-insulating board is prolonged, and the strength and heat insulation, sound insulation and fire prevention properties of the vacuum heat-insulating board can be increased.

Description

technical field

[0001] The invention relates to the technical field of building energy conservation, in particular to a vacuum heat insulation board and a manufacturing method thereof. Background technique

[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. Therefore, relevant parts of the state have explicitly prohibited the use of organic thermal insulation materials for external wall insulation, especial...
