Composite thermal insulation material can be made from expanded and vitrified small balls and other inorganic insulation lightweight aggregate. According to the hydration, hardening mechanism of inorganic gel material and materials thermal insulation mechanism, we can eliminate the heat convection of gas inside the holes by using foaming technology, and micro holes can reduce radiation heat transfer between the pore walls so as to further improve the thermal insulation properties of solid materials.

Vitrified micro bubbles thermal insulation material was made of vitrified micro bubbles, cement, fly ash, gypsum and sodium silicate, by molding process. VAE emulsion and stearic acid-polyvinyl alcohol emulsion were added to improve water resistance of the material. Mixed with 10% VAE emulsion and 5% stearic acid-polyvinyl alcohol emulsion, properties of the material are followed as: flexural strength 0.64MPa, compressive strength 1.35MPa, softening coefficient 0.71 and 2h volumetric water absorption 6.9%.
