Referring to fig. 1-2, a vacuum insulation panel 1 for building includes a bottom plate 11, a cover plate 12 and an air bag 2, wherein the bottom plate 11 and the cover plate 12 are hermetically connected into a whole and then the inside is evacuated to form a first vacuum chamber 10, the air bag 2 is disposed in the first vacuum chamber 10 and connected to the inner wall of the first vacuum chamber 10, and the inside of the air bag 2 is evacuated to form a second vacuum chamber 20.

Specifically, the material of the bottom plate 11 and the cover plate 12 is not limited, and is a conventional building material, such as a cement board, a gypsum board or a heat insulation board; preferably insulation boards such as XPS boards, polyurethane insulation boards.

Further, the first vacuum chamber 10 or the second vacuum chamber 20 is filled with aerogel. Preferably, the second vacuum chamber 20 is filled with aerogel so that the balloon 2 is supported with only a slight heat-conducting effect. The aerogel may be selected from one of silica aerogel, nanofiber aerogel or silica aerogel doped with peptide dioxide.

The bottom plate 11 and the cover plate 12 are formed with a plurality of first connection lugs 13 which are uniformly distributed on the inner walls thereof, and a plurality of second connection lugs 21 which are uniformly distributed and connected with the first connection lugs 13 are formed on the outer wall of the airbag 2. Specifically, a plurality of first connection lugs 13 are formed on the lower bottom surface of the bottom plate 11 and the upper surface of the cover plate 12, and a plurality of second connection lugs 14 are formed on the upper and lower outer surfaces of the airbag 2, so that the upper and lower surfaces of the airbag 2 are hung on the bottom plate 11 and the cover plate 12, and the airbag is prevented from sinking to cause the upper and lower surfaces to be attached together due to the reduction of the air leakage vacuum degree of the first vacuum chamber 10, and then an additional heat conduction path is formed at the attachment point, and the heat insulation effect is reduced.

Further, the vacuum insulation panel 1 for building provided by the present invention further comprises a getter group 3 disposed at the connection between the bottom plate 11 and the cover plate 12 of the inner wall of the first vacuum chamber 10. In actual production, when the airbag 2 is placed in the first vacuum cavity 10, the plurality of getters are fixed at the sealing connection position of the bottom plate 11 and the cover plate 12, the getters can adsorb trace gas leaked from the sealing position, and meanwhile, the airbag 2 can be pressed against the first vacuum cavity 10, so that the airbag 2 is prevented from being attached to the inner wall of the bottom plate 11 or the cover plate 12 to form new heat conducting points, and the heat conducting effect is reduced. The getter 3 can be a non-evaporable getter such as a zirconium aluminum 16 getter, a zirconium graphite getter, a zirconium nickel getter or a zirconium iron vanadium getter.

Further, the utility model provides a vacuum insulation panel for building, two relative lateral walls of apron 12 are formed with first connecting portion 120 and the second connecting portion 121 of mutual grafting cooperation respectively.
