Abstract

In order to obtain flame retardants with good heat resistance, retardant properties and affinity, magnesium hydroxide (MH)/siloxane nanocomposite flame retardants were prepared by the hydrothermal and hypergravity method. The MH and MH/siloxane particles were characterized and analyzed by transmission electron microscopy (TEM), Brunner-Emment-Teller (BET) measurements, thermogravimetric analysis (TGA), etc. The results show that the stability of as-prepared MH/siloxane nanocomposite flame retardants is superior to MH particles prepared by other prepared methods, and the agglomeration is significantly reduced. The specific area of the composite particles was reduced, and the affinity and thermal stability were effectively improved. As a kind of filler for polymer, the MH/siloxane nanocomposite could help to improve the reinforcement of the polymer, and the heat resistant and flame retardant properties, which provide the foundation for further application of this nanocomposite as a flame retardant.

Keywords: flame retardant; MH/siloxane nanocomposite; surface modification; thermal stability
