Example Embodiment

[0027] The present invention is a method for producing a new type of vacuum insulation board. The core material is put into a high gas barrier film bag, and then sealed after being evacuated. It is characterized in that the composition and weight parts of the core material are: fumed silica and 60-80 parts of microsilica powder in any ratio, 3-6 parts of carbon black, 10-20 parts of fiber, 3-5 vacuum active stabilizer, 2-4 parts of getter;

[0028] The production process includes the following steps:

[0029] (1) Ingredients: Put the materials of the formula into the mixer according to the above ratio and mix them fully.

[0030] (2) Drying: Dry the well-stirred mixture at 100-120℃, and measure the moisture content of the mixture every 8 minutes during the drying process until the moisture content of the mixture reaches 0.5% Next, stop drying.

[0031] (3) Core material molding: Pre-lay the cut non-woven fabric into the bottom of the mold, put the dried material into the mold, and sc...

Abstract

The invention discloses a method for producing a novel vacuum insulated panel. The method comprises the following steps of: material mixing: putting fumed silica, microsilica, carbon black, fibers and a vacuum active stabilizer into a mixer for complete mixing; drying: drying the uniformly stirred mixture; core material molding: putting the dried mixture and a getter into a mold, and putting the mold into a pressing machine for extrusion forming; packing: taking the formed core plate out of the mold and wrapping the core plate with a layer of non-woven fabric to obtain the core plate of the vacuum insulated panel; putting the core plate into a high-resistance air film bag for vacuuming until a vacuum degree is 0.02-20 Pa, and sealing the high-resistance air film bag. The method has the advantages that the fumed silica, the microsilica and the fibers are mixed together so that the strength of the insulated panel is improved, the insulation performance is improved and low heat conductivity is obtained, and the fumed silica, the microsilica and the fibers are inorganic materials and are difficultly combusted. The carbon black has large specific surface area, can absorb residual moisture in the core material and can assist the vacuum active stabilizer in maintaining vacuum in the bag.

Description

technical field [0001] The invention relates to a production method of a novel vacuum heat insulation panel, which is used for producing the vacuum heat insulation panel, which is used as a building or industrial heat preservation material. Background technique [0002] Existing vacuum insulation panels are mainly composed of internal heat-insulating core material and outer high-barrier film, in which the heat-insulation core material is generally made of conventional thermal insulation materials (such as foamed plastics), glass fiber or / and airgel, etc. Its disadvantages are high material cost, high energy consumption and not environmental protection. Contents of the invention [0003] The invention aims to provide a novel production method of vacuum insulation panels to solve the problems of high material cost, high energy consumption and environmental protection in the prior art. [0004] The technical solution of the present invention is: a novel production method of ...
