Double-vacuum-layer ceramic composite vacuum plate with getters and preparation method of double-vacuum-layer ceramic composite vacuum plate

Abstract

A double-vacuum-layer ceramic composite vacuum plate with getters comprises face plates, connecting layers and a vacuum chamber and is characterized in that the face plates are made of ceramic plates or ceramic tiles; the face plates and / or the connecting layers provide additional strength for the vacuum chamber, so that smoothness of the vacuum chamber under atmosphere is guaranteed; the vacuum chamber is a sealed cavity which is formed in the mode that the edges of metal plates are sealed in a welding mode under normal pressure and the openings of the metal plates are sealed by high temperature under vacuum; the opening sealing operation is conducted as follows: an extraction opening preformed in the vacuum chamber is automatically sealed in a vacuum furnace by low-temperature welding fluxes on the basis of the liquid sealing principle; a partition plate is arranged in the vacuum chamber and divides the vacuum chamber into double vacuum layers; upholders are arranged in the vacuum layers. A method for manufacturing the double-vacuum-layer ceramic composite vacuum plate with the getters is simple in process, the prepared double-vacuum-layer ceramic composite vacuum plate with the getters can overcome the defects of an existing heat preservation plate and an existing vacuum heat insulation plate, and strength, heat and sound insulation performance and fireproof performance of the double-vacuum-layer ceramic composite vacuum plate with the getters can be improved.

Description

technical field [0001] The invention relates to the technical field of building energy conservation, in particular to a double-vacuum-layer ceramic composite vacuum panel with a getter and a manufacturing method thereof. Background technique [0002] 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 one of the main means to reduce building energy consumption. At present, many materials used for building exterior wall insulation are 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. A large amount of toxic smoke can accelerate the spread of the fire; at the same time, organic materials will shrink during a fire, producing burning droplets, causing the tiles on the insulation layer to fall off, wh...
