Magnesium oxide is a new type of filled flame retardant. It releases bound water and absorbs a large amount of latent heat to reduce the surface temperature of the synthetic material it fills in the flame by decomposing the polymer. Combustible gas for cooling. Magnesium oxide is a promising inorganic flame retardant filler for polymer matrix composites. Like alumina, magnesium oxide flame retardants rely on chemical decomposition to absorb heat and release water to play a flame retardant role when heated. Therefore, it has non-toxic, low smoke and chemical properties of magnesium oxide generated after decomposition, and does not produce two. secondary pollution and other advantages.

However, in order to achieve a considerable flame retardant effect, the filling amount should generally reach more than 50%. Since magnesium oxide is an inorganic substance, the compatibility of the surface with the polymer base material is poor. Such a high filling amount, if it is not subjected to surface modification treatment, will cause the composite material to deteriorate after being filled into the polymer material. Mechanical properties decreased. Therefore, it is necessary to carry out surface modification treatment to improve its compatibility with the polymer base material, so that the mechanical properties of the filling material do not decrease, and even some of the mechanical properties of the material are improved.
