Embodiment 1

[0019] Select 95% white corundum material as the inner lining of the grinding machine, and use 95% white corundum balls of different specifications to crush and grind ordinary flat glass, carbon black powder, metal powder and foaming agent into 100-mesh powder respectively . Due to the high hardness of white corundum, impurities can be avoided to affect product quality. Then weigh 0.2% nickel powder and 0.2% aluminum oxide by mass fraction, and 1% foaming agent and the rest of ordinary flat glass powder, mix them evenly, and put them into a mold box with specific specifications. The specifications of the rectangular mold box are less than 800 mm in length, 600 mm in width, and 200 mm in thickness, and the specifications of the curved mold box are less than 600 mm in length, 30-180 degrees in arc, and less than 200 mm in thickness. Push the mold box containing the mixed powder into the front section of the heating kiln for preheating and drying at 450-600°C, control the temper...

Abstract

The invention discloses an anti-static foam glass heat insulation and cold insulation material and a preparation method thereof. The preparation method comprises the steps of: carrying out ultra-refining fusion permo-treatment on a special high-temperature resistant conductive metallurgical powder material and a metal oxide serving as adding materials for realizing phase modification; controlling the combustion atmosphere by using a special process, expanding at a high temperature and sintering for forming; and finally, annealing and cooling to prepare the anti-static foam glass heat insulation and cold insulation material. The anti-static foam glass heat insulation and cold insulation material maintains the advantages of water prevention, heat insulation, cold insulation, water and moisture prevention, good chemical stability, sound insulation, noise reduction and the like of foam glass, and has a permanent conductive (static) and static dissipative function. The use space and the application range of the foam glass material are expanded.

Description
