Abstract

The invention discloses an inorganic compound open-cell foamed vacuum insulation panel core material and a preparation method thereof. The vacuum insulation panel core material is prepared from the following components as raw materials in parts by weight: 80 to 120 parts of cement, 15 to 50 parts of mineral admixture, 50 to 100 parts of open-cell foaming agent, 0.5 to 2 parts of foam stabilizer, 0.3 to 1 part of water reducing agent, 0.3 to 1 part of water repellent, 2 to 8 parts of reinforced fiber, and 35 to 60 parts of water. The vacuum insulation panel core material is prepared by adopting inorganic raw materials and has excellent performances, such as low heat conduction coefficient, low water absorption, low density, A-level non-combustion; meanwhile, no three wastes is generated in a production process of the core material, the energy consumption is reduced, the production is controlled.

Description
