Ceramic composite vacuum insulation board and preparation method thereof

Abstract

Provided is a ceramic composite vacuum insulation plate. The ceramic composite vacuum insulation plate comprises panels, connecting layers and a vacuum chamber. The ceramic composite vacuum insulation plate is characterized in that the panels are ceramic plates or ceramic tiles, the panels and / or connecting layers provide additional strength for the vacuum chamber to ensure flatness of the vacuum chamber under the atmospheric pressure. The vacuum chamber is a closed chamber body which is formed by a metal plate in the mode that the edges of the metal plate are welded to be sealed under the normal pressure and high-temperature sealing is carried out on the metal plate under the condition of the vacuum, and the sealing is carried out, namely an air suction opening formed in the vacuum chamber in advance is automatically sealed by using low-temperature solder according to the liquid sealing principle in a vacuum furnace. The low-temperature solder comprises low-temperature metal and alloy solder. Supporting objects are arranged in the vacuum chamber. A preparation method of the ceramic composite vacuum insulation plate is simple in technology. The prepared ceramic composite vacuum insulation plate can overcome the defects of an existing insulation plate and an existing vacuum insulation plate, can effectively ensure the air tightness of the vacuum chamber, prolong the service life, and improve strength, thermal insulation performance, soundproof performance and fireproof performance.

Description

technical field [0001] The invention relates to the technical field of building energy conservation, in particular to a ceramic composite vacuum heat insulation board 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, which may cause seco...
