“…Therefore, inorganic heat preservation materials cause people's more and more attention, and it is fireproofing and stable performance that set them entirely apart from the organic. Most of the inorganic are characterized by foamed internal structure [5][6][7], but undoubtedly, these foams cause adverse effects on strength and water resistance of the material. Although excellent in mechanical strength and stable performance, vitrified micro bubbles thermal insulation material through molding process is poor at water resistance.…”

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%.

This is the author accepted manuscript. The final version is available from Elsevier via http://dx.doi.org/10.1016/j.jallcom.2017.04.070The pursuing aim of high reflection loss and broad frequency bandwidth for electromagnetic wave (EMW) absorbing materials is a long-term task and under a close scrutiny. To construct rational microstructures for the absorber have significant impacts on increasing reflection loss and broadening frequency bandwidth. Herein, we presented a sandwich microstructured expand graphite (EG)/BaFe12O19 (BF) nanocomposite successfully prepared by in-situ sol-gel auto-combustion method. The experimental results showed that EG/BF nanocomposite has better EMW absorbing performance than pure EG and BF, the sandwich microstructured EG/BF connected with carbon nanotubes (CNTs) could further improve the electromagnetic performance effectively. The obtained CNT/EG/BF nanocomposite exhibited a saturation magnetization of 26.5 emu g?1 at room temperature and an excellent EMW absorbing performance. The maximum reflection loss of the sandwich microstructured CNT/EG/BF composites with a thickness of 1 mm was up to ?45.8 dB and the frequency bandwidth below ?10 dB could reach to 4.2 GHz within the frequency range of 2?18 GHz. The research results indicated that the prepared nanocomposite showed great potential as a new type of microwave absorbing materialPeer reviewe
