Abstract
The invention discloses a kind of magnalium laminar double-hydroxide synergistic oxidation antimony compound flame retardants, including following raw material: polybutylene terephthalate (PBT), antimony oxide, magnalium laminar double-hydroxide, subcarbonate, organic ammonium bromide, methyl-silicone oil, acrylate, dispersing agent, the mass ratio of the subcarbonate, organic ammonium bromide be (0.1-2.5): (0.5-5), the methyl-silicone oil, acrylate mass ratio be (0.5-5): (0.5-3).The present invention realizes the substitution with modified magnalium laminar double-hydroxide to antimony oxide by modification technology and compounded technology, while can form cooperative flame retardant system by introducing halogen atom and antimony oxide, effectively improves the properties of compound flame retardant.
Description
Technical field
The invention belongs to technical field of flame retardant agent preparation, and in particular to a kind of magnalium laminar double-hydroxide synergistic oxidation antimony
Compound flame retardant.
Background technique
The tradition halogenated flame retardant such as polyhalo biphenyl can release two uh English class environment using and recycle in incineration course
Pollutant is high poison carcinogenic substance.China ＂ 11th Five-Year ＂ national science and technology supporting plan will develop the rings such as Halogen magnesium system, hydrogen system and phosphorus system
Guarantor's type fire retardant new product is classified as emphasis and supports project.The application amount of the inorganic fire retardants of developed country is up to 50% or more at present,
Mainly Al (OH)3With Mg (OH)2.And remain halogenated flame retardant in China market and occupy the majority, inorganic resistance will be greatly developed from now on
Fire agent.Meanwhile global three big halogenated flame retardant supply companies are also in the exploitation for turning to inorganic fire retardants.
It is magnesium hydroxide and aluminium hydroxide in the inorganic fire-retarded middle maximum fire retardant of yield.This substance has thermal stability
It is good, fire-retardant, nontoxic, non-volatile, do not generate that corrosive gas, smoke amount are small, do not generate the advantages that secondary pollution, it is poly- when being added to
It closes in object, has both filling, fire-retardant and suppression cigarette triple functions.Both additive flame retardants, fire retardant mechanism are roughly the same.But
The based flame retardant to reach preferable flame retardant effect additive amount and often to reach 50% or more, and high additive amount make it is fire-retardant
The dispersibility and poor compatibility of agent in the polymeric material, leverage the mechanical property of material.Therefore often through ultra-fine
Change and surface is modified to improve flame retardant property and improve compatibility.
In recent years, as what micropore, mesoporous material, inorganic-organic, inorganic-inorganic nanocomposite were studied gos deep into, one
Multifunctional inorganic compound --- the research of lamellar compound becomes hot spot concerned by people to kind again.The structure of lamellar compound has
It has specific characteristics, itself is a kind of special nanostructure, while but also as preparing inorganic-inorganic, inorganic-organic nano
The fertile material of composite material can provide new thinking to synthesize new nanostructure.In addition, lamellar compound and its modified material
It has broad application prospects in numerous areas such as ion exchange, absorption, conduction, separation and catalysis, changes about lamellar compound
Property and its application study attract the sight of a large number of researchers.
Layered double hydroxide (being abbreviated as LDHs) is a kind of Typical anionic with houghite layer structure
Type lamellar compound has the characteristics that unique structure and composition, shows in terms of high molecular fire retardant material good using valence
Value and application prospect.Currently, because the special layer structure of magnalium type layered double-hydroxide (MgAl-LDHs) makes it in polymer
Fire-retardant aspect is widely used, and is combined the fire-retardant advantage of magnesium hydroxide and aluminium hydroxide, is become the nothing of most researching value
Machine halogen-free flameproof fires agent.Seep appropriate miscellaneous and interlayer intercalation technique by laminate and suitable other divalent of introducing or trivalent metal from
Son constructs new LDHs, to enriching polymer/laminated hydroxide type, expands its fire-retardant application with highly important meaning
Justice.But still have some problems to the modification of such compound at present: for example (1) utilizes the disastrously miscellaneous synthesizing new LDHs of laminate
When, the type and the miscellaneous concentration of infiltration of laminate ion influence the balance of layer structure, are easy to cause laminate to study carefully and collapse.((2) are simple
MgAl-LDHs flame retardant effect is not ideal enough and but without resistance to UV aging, and polymer is chronically exposed under illumination easily
Aging and fail.(3) LDHs fire retardant and polymer to study carefully capacitive poor, to reach preferable flame retardant effect generally require it is larger
Additive amount so that polymerization mechanical properties decrease.In view of the above-mentioned problems, to the doping of LDHs laminate and area load, preparation is multiple
Mould assembly LDHs probes into influence of the doping particle to LDH structure, is of great significance to its application in flame retardant area is widened.
Antimony is a kind of widely used non-renewable strategic rare metal, be in the big rare strategy metal in China ten the most
Rare kind is that China takes one of strategy metal of protective mining.The consumption of whole world antimony is mainly fire-retardant in antimony system at present
Agent field accounts for about the 70% of global antimony consumption, accounts for 80% or more of antimony oxide consumption.Since the selecting smelting of antimony ore is in
Disordered state, private, which digs coyoting, adopts richness loses that poor, primary product are more, high value added product lacks the factors such as additional disorderly competition, China's antimony
Mine depletion rate is far longer than the growth rate of recoverable reserves.China's antimony product specie accounts for the 70% of world's gross reserves, however antimony product yield
But 80% or more of Gross World Product is accounted for.Antimony depletion rate is too fast to cause storage level to reduce year by year, and Backup Base is obviously insufficient.
According to it is related authority prediction, current antimonial resources if do not strengthened management, will future 10 years it is depleted, China's antimony resource it is excellent
Gesture will also disappear therewith.So that China's antimony industry is gone on sustainable development road, is the matter of utmost importance of current antimony industry.It removes
Outside national appearance correlation protection restrictive policy, passes through tackling of key scientific and technical problems and research and develop related deep processed product, full substitution or part and substitute
Product, it is one of solution that adjustment, which even changes antimony product consumption structure,.
