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

Embodiment 1

[0072] Example 1: see figure 1, the two heat shields are commercially available ceramic heat shields, one of which is a low-radiation heat shield with an aluminum film, and there are edge bands on the two heat shields. The production method is as follows: first After the ceramic heat insulation board is cleaned and dried, use printing technology to print the low-temperature glass powder paste on the two heat insulation boards to make edge banding frames. edge banding frame, the size of the edge banding frame of the upper insulation board is between the two edge banding frames of the lower insulation board, after the upper and lower insulation boards are combined, the edge banding frame of the upper insulation board can be embedded Fit between the two edge banding frames of the lower heat shield, each edge banding frame has a width of 1.5mm and a height of 0.7mm; secondly, send the two heat shields into the high temperature furnace respectively, and in the high temperature furn...

Embodiment 2

[0075] Example 2: see figure 2 , The vacuum heat insulation board is composed of an upper ceramic heat insulation board and a lower ceramic heat insulation board, and the two heat insulation boards are surrounded by edge sealing strips. The production method is as follows: firstly, according to the shape and size of the vacuum insulation panel to be produced, the metal stamping dies for the upper and lower insulation panels are respectively prepared. There are grooves around the mold to form the edge banding frame on the insulation panel. There is one edge banding frame on the upper heat shield, and two edge banding frames on the lower heat shield. The size of the edge banding frame on the upper heat After the hot plates are combined, the edge banding frame of the upper heat insulating plate can be fitted between the two edge banding bars of the lower heat insulating plate; secondly, the raw materials for making the ceramic heat insulating plate are put into the mold, and pre...

Abstract

The invention provides a vacuum ceramic thermal baffle. The thermal baffle comprises an upper thermal baffle and a lower thermal baffle, wherein the peripheries of the upper and lower thermal baffles are welded together by metal or alloy solders; a closed vacuum layer is formed between the upper thermal baffle and the lower thermal baffle; and the upper and lower thermal baffles can be flat, flat externally and concave internally, or convex. A manufacturing method of the vacuum ceramic thermal baffle is simple in process. According to the invention, the manufactured vacuum ceramic thermal baffle can overcome defects of the conventional thermal baffle, the air tightness of the vacuum layer of the thermal baffle can be effectively ensured, the service life of the thermal baffle can be prolonged, the strength, sound insulation and fireproof performance of the thermal baffle can be improved, and the thermal baffle also can achieve a good decoration effect.

Description

technical field [0001] The invention relates to the technical field of building energy saving, in particular to a vacuum ceramic 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, especi...
