Two kinds of elements of nitrogen play synergism in wood fire retardant and improve flame retardant effect；But these fire retardants almost have one jointly
Feature, it is simply that reducing the thermal degradation temperature of the wood fiber significantly, this may result in the processing that cannot be carried out composite；Right
Also a lot of in the research of polyolefin flame-retardant, its flame resistant method is frequently with halogen containing flame-retardant and antimony oxide (Sb2O3) coordinate make
With；Metal hydroxides (Al (OH)3、Mg(OH)2) fire retardant；Expansibility flame-proof agent；Ammonium polyphosphate flame retardant etc.；Halogen-free flameproof
The focus of polyolefin flame-retardant research, expanding fire retardant polyolefin/Wood Fiber Composites is carried out dual fire-retardant be this be combined
The focus of the fire-retardant research of material；But the interpolation of fire retardant often deteriorates the mechanical property of composite, therefore to fire-retardant multiple
The research of the research flame-proof composite material of condensation material to study interface compatibility, heat stability and anti-flammability, to obtain reason simultaneously
The flame-proof composite material thought.
