Problems solved by technology

[0004] B. The water-resistant strength is low, and it will deform after absorbing water. Some insulation materials do not use the strength after water-resistance as their detection index, resulting in that they cannot be used once they absorb water.
[0005] C. More brittle, loose and more damaged

Abstract

The invention discloses an inorganic modified heat insulation plate and a preparation process thereof. The inorganic modified heat insulation plate has the following components in parts by weight: 60-95 parts of inorganic light-weight material, 0.5-1 part of organic light-weight material, 3-8 parts of inorganic cementing material, 8-15 parts of organic cementing material, 3-8 parts of waterproofing agent, 3-8 parts of flame retardant and 30-32 parts of fly ash and/or graphite. The heat insulation plate has the nonflammability under the conditions of fire-protection rating A (A2) GB8624-2012, not only has lower thermal conductivity but also has excellent water resistant strength and good resistance against tension and compression, so that good weatherability is guaranteed.
