The method for improving flame retardance of polymer performance can be divided into two big class, and the first kind is, by MOLECULE DESIGN, to give polymer point
Sub- ignition-proof element or flame retarding construction, so as to improve the fire resistance of polymer；Equations of The Second Kind is by adding fire retardant, so as to improve
The fire resistance of polymeric material.Wherein, Equations of The Second Kind is the wide variety of method of plastics industry, with technology maturation, low cost
And it is easy to process the advantages of.Conventional fire retardant has bromide fire retardant, APP, hydroxide trick, magnesium hydroxide, red phosphorus and three
Poly cyanamid etc..Over nearly 15 years, flame-retardant polymer nano composite material has obtained extensive research.Wherein, polymer laminar without
Machine thing nano composite material, it is only necessary to less addition, you can obtain obvious flame retardant effect, and environmental protection, be considered
One of important developing direction of field of fire-proof technology；
The lamella blocking effect of graphene sheet layer is the heat stability and fire safety for improving graphene/polymer nano composite material
The principal element of performance, and its high-termal conductivity often leads to the reduction of polymer nanocomposites pyrolysis temperature, ignition temperature and carries
Before.But, with regard to the interfacial interaction between Graphene and polymer in GPNC heat stability and fire safety performance is improved
Effect, also clearly do not studied；The high-termal conductivity of Graphene is unfavorable for which improves polymer thermostable and fire peace
Full performance.The physics and chemical property of Graphene can be changed by surface modification, so as to open up a raising Graphene/polymerization
The technology path of thing nano composite material heat stability and fire safety performance.The research of flame retardance of polymer technical field shows, portion
Divide transition metal that there is the effect of catalyzing and carbonizing and capture free radical, be conducive to improving the heat stability and anti-flammability of polymer
Can, such as, zirconium is acted on catalysis carbon-forming in the pyrolysis of polymer and combustion process, and nickel is not only acted on catalysis carbon-forming,
Also there is the effect of absorption free radical.Therefore, transition metal is supported on Graphene, it is possible to have than simple Graphene
The effect of heat stability and fire safety performance is improved preferably.
