Description
Technical field
The present invention relates to building material technical field, more particularly to a kind of polystyrene building for being incubated carrying transition metal
Material and preparation method thereof.
Background technology
Polymer nanocomposites（By polymeric matrix（Continuous phase）With nano-filled dose（Dispersed phase）Composition.Wherein,
The nano-filled dose of yardstick of at least one dimension is less than nanometer.Good dividing is formed in polymeric matrix when nano-filled dose
Dissipate, can significantly improve the performance of nano composite material.Compared to traditional polymer composites, polymer nanocomposite composite wood
The consumption of the filler of material is low, effect is significant；
The performance of polymer nanocomposites is influenceed by two big factors：Dispersed and nano-filled dose of nano-filled dose with
Interfacial interaction between polymeric matrix；Dispersiveness（Dispersiveness refers to dispersion feelings of the nano-particle in polymeric matrix
Condition.Nano-particle generally has stronger reunion to be inclined to, and causes the specific surface area of filler to reduce, between influence filler and matrix
Surface can and interfacial interaction, so as to influence the performance of composite, interfacial interaction：Nano-filled dose and polymer
Interfacial interaction between matrix is to cause the key factor of changes in material properties, and important to being dispersed with for nano-particle
Influence.When interfacial interaction is stronger, nano-particle easily forms good dispersion, and the performance of composite is improved more
Substantially；
Polymer laminar compound nano composite has lot of advantages, and first, dispersed phase is two-dimensional layer nano material, than
Surface area is big；Secondly, two-dimensional layered structure formed lamella blocking effect, can significantly increase material gas barrier property and
Heat endurance；Again, many performances can simultaneously be improved；
The fire safety performance of polymeric material is the important topic that polymer grinds the field of making internal disorder or usurp.The fire of polymer
Security performance when security refers to polymer combustion, mainly discharges including ignition temperature, the combustion heat, poisons
The contents such as the release of property flue gas.Polymer is widely used in the every field of human being's production and life.Most polymers
Main component be carbon and hydrogen, be susceptible to decompose and burn when being heated, belong to combustible material.During polymer combustion, release
Substantial amounts of light, heat and toxic flue gas are released, is to cause the main cause of casualties in fire.Improve polymeric material fire peace
The technology of full performance is commonly known as flame-retarded technology；
Improving the method for flame retardance of polymer performance can be divided into two major classes, and the first kind is, by MOLECULE DESIGN, to assign 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 as
One of important developing direction of field of fire-proof technology；
The lamella blocking effect of graphene sheet layer is the heat endurance 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, on the interfacial interaction between Graphene and polymer in GPNC heat endurances and fire safety performance is improved
Effect, do not studied clearly also；The high-termal conductivity of Graphene is unfavorable for that it improves polymer thermostable and fire is pacified
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 endurance and fire safety performance.The research of flame retardance of polymer technical field shows, portion
Dividing transition metal has the effect of catalyzing and carbonizing and capture free radical, is conducive to improving the heat endurance and anti-flammability of polymer
Can, such as, zirconium is acted in the pyrolysis of polymer and combustion process with catalysis carbon-forming, 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
Preferably improve the effect of heat endurance and fire safety performance.
