[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...
