Description

A kind of polystyrene construction material of anti-corrosion carrying transition metal and preparation method thereof
Technical field
The present invention relates to building material technical field, more particularly to a kind of polystyrene building of anti-corrosion carrying transition metal Material and preparation method thereof.
Background technology
Polymer nanocomposites（By polymeric matrix（Continuous phase）With nano-filled dose（Dispersion phase）Composition.Wherein, The yardstick of nano-filled dose 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 affected by two big factors：Nano-filled dose of dispersibility and nano-filled dose with Interfacial interaction between polymeric matrix；Dispersibility（Dispersibility refers to dispersion feelings of the nanoparticle in polymeric matrix Condition.Nanoparticle generally has stronger reunion tendency, and the specific surface area for causing filler reduces, affects between filler and matrix Surface energy and interfacial interaction, so as to affect the performance of composite, interfacial interaction：Nano-filled dose and polymer Interfacial interaction between matrix is the key factor for causing changes in material properties, and important to being dispersed with for nanoparticle Affect.When interfacial interaction is stronger, nanoparticle easily forms good dispersion, and the performance of composite is improved more Substantially；
Polymer laminar compound nano composite has lot of advantages, and first, dispersion phase is two-dimensional layer nano material, than Surface area is big；Secondly, two-dimensional layered structure forms lamella blocking effect, can significantly increase material gas barrier property and Heat stability；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
Safety refers to security performance during polymer combustion, mainly discharges, poisons including ignition temperature, the combustion heat
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 the main cause for causing 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 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 that it 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 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 stability and fire safety performance.
