Description
Technical field
The present invention relates to field of compound material, more particularly to a kind of flame-retardant polypropylene composite material and preparation method.
Background technology
Polypropylene (PP) is a kind of resins for universal use, nontoxic, tasteless, odorless, light white particle, has good electricity absolutely
Edge performance, resistance to chemical corrosion, water vapor, and its processing and forming is convenient, cost price is low, is widely used in electricity
The industries such as device, furniture, packaging for foodstuff.But because polypropylene (PP) belongs to combustible material, its oxygen index (OI) (LOI) is very low, and is firing
Substantial amounts of molten drop is produced during burning.Therefore, to carry out under many circumstances flame-retardant modified, China's fire retardant is started late, 1979
Beijing Chemical Research Institute has started fire-retardant PP research, and the polypropylene flame redardant tree for television set industry was manufactured experimently out in 1981
Fat, vicennial developmental research is have passed through again, be developed the flame-retardant system such as halogen-free flame-retardant system, smokeless of a series of new
Flame-retardant system, Intumescent Retardant System etc..Domestic fire retardant kind only has kind more than 40 within 1985, and annual production is about 5000t；But arrive
1998, the annual production of domestic fire retardant was up to t more than 70,000, and 2000 annual requirements are up to t more than 90,000.China's fire retardant aggregated capacity at present
About 150,000 t, wherein chlorine-based flame retardant account for 75%, phosphorus system (containing halogenation) fire retardant and account for 6%, bromide fire retardant and account for 7%, nothing
Machine fire retardant accounts for 12%.
In conventional fire retardant, the nitrogen class expanding fire retardant (IFR) of phosphorus one is most popular, Feng Caimin research IFR (MPP with
PEPA is compounded and mass ratio is 3：2) different amounts can obtain to the performance impact of PP/IFR mixing materials, in PP/IFR mixing materials
During middle addition 20%IFR, limited oxygen index reaches 27% or so, UL-94 and reaches V-0 levels；Thermal gravimetric analysis results show, add
The decomposition of PP/IFR mixing materials can be delayed after IFR；The activation energy of material has been asked for using Kissinger methods, has added IFR
Afterwards, the activation energy of PP/IFR mixing materials improves；And after adding IFR, PP/IFR mixing materials form foamed char, improve
PP fire resistances.The IFR of the researchs such as Feng Caimin is that MPP and PEPA is compounded and obtained, and contains phosphate in MPP and PEPA, can
PP/IFR mixing materials surface is covered in form poly-metaphosphoric acid, promotes into charcoal, plays a part of heat-insulating flame-retardant；MPP and PEPA
The common solid phase that participates in acts on into carbon flame-proof, while the melamine in MPP decomposes and plays the fire-retardant work of gas phase；MPP and PEPA make
Significantly increased into charcoal effect, neat coal amout increase, layer of charcoal can more effectively play heat-insulated oxygen barrier, put forward the heat endurance of material
It is high.
In recent years, the method for polypropylene (PP) addition fire retardant had following two methods：First, the side for passing through mechanical mixture
Fire retardant is added in PP by method, so as to reach fire-retardant purpose.Second, reactive flame retardant is grafted to PP main chain or side
On chain, when fire retardant and PP chemically react, PP molecular structure can be heavily disturbed, phosphorus system in ignition-proof element, nitrogen system,
The structures such as antimony system, aluminum-magnesium series, Phos system can all obstruct the heat transmission between molecular structure, MODIFIED PP is had anti-flammability,
As environmentally friendly appealing sound increasingly improves, because halogenated flame retardant smoke amount is big, release toxic gas, the PP fire retardants that progressively fade out neck
Domain, although and study more expansion type flame retardant environmental protection at present, flame retardant effect is less obvious, oxygen index (OI) relatively low and does not have
The defects of polypropylene material can be overcome to be easy to melting drippage, utilization rate is not high, therefore how to solve these problems will turn into fire-retardant
The important research direction of PP materials.
The content of the invention
The present invention is in order to solve the above technical problems, provide a kind of flame-retardant polypropylene composite material and preparation method.
Realized particular by following technical scheme：
A kind of flame-retardant polypropylene composite material, it is made up of following raw material by weight：Polypropylene 55-100 parts, poly- phosphorus

Alcohol 3-12 parts, melamine cyanurate 3-8 parts, salt slurry 5-15 parts.
Described APP, and pentaerythrite, it is by 3：What 2 mass ratio was compounded.
The preparation method of the flame-retardant polypropylene composite material, comprises the following steps：
(1) banburying：Polypropylene, APP, pentaerythrite, melamine cyanurate and salt slurry are weighed by formula, is put
1 must be expected by entering progress banburying in banbury；
(2) hot pressing：1 will be expected by vulcanizing press hot pressing, obtain material 2；
(3) it is cold-pressed：Material 1 is cold-pressed by vulcanizing press, produces composite of the present invention.
Described banburying, regulation banbury temperature is 160~200 DEG C, and closed-smelting machine rotor rotating speed is 35~45r/min, close
Refine 5~10min.
Described hot pressing, hot pressing time are 6~10min.
Described cold pressing, cold pressing time are 8~12min.
In summary, the beneficial effects of the present invention are：The present invention is using polypropylene as matrix material, with APP, season
Penta tetrol, melamine cyanurate and salt slurry are raw material, by flame-retardant polypropylene composite material made from melt blending, are passed through
Rational raw material and proportion relation so that composite prepared by the present invention, flame retardant effect is obvious, has higher limit oxygen
Index, the effective conventional expanded type fire retardant limited oxygen index that improves is low, the defects of easily drippage, effectively increases polypropylene and answers
The utilization rate of condensation material.
