Description
Technical field
The present invention relates to the modified field of polypropylene material, in particular to a kind of low-gravity V0 grades of flame-retardant polypropylene composite materials
And preparation method thereof.
Background technique
Polypropylene is widely used in vapour due to facilitating with excellent mechanical performance, the small light weight of density, processing
The fields such as vehicle, household electrical appliances, electronic apparatus industry, however polypropylene oxygen index (OI) is low, only 18% or so, it is easy to it burns, inflammability
Limit its application on electric equipment products, it is therefore desirable to do to polypropylene material flame-retardant modified.UL94-V0 grades are higher
The flame retardant property of rank prepares the fire retardant that V0 grades of flame-retardant polypropylene composite materials need to be added larger proportion in formula, leads to
Normal ratio is 20% or more, and fire retardant density is big more than polypropylene, therefore final V0 grades of polypropylene flame redardant composite woods obtained
Expect that density is larger, the product of final injection molding is also than heavier.
Chinese patent CN201210158873 is using decabromodiphenylethane and three oxidations, two ladder and the composite modified system of zinc borate
Standby V0 grades of flame-retardant polypropylene composite materials, 20% or more fire retardant accounting, and a certain proportion of mineral are also added in formula
Filling, so that material final densities are 1.36, it is more much larger than virgin pp；Chinese patent CN201310363074 uses polyphosphoric acid
The compound flame retardants modified polypropene such as ammonium, melamine or melamine polyphosphate, pentaerythrite prepares V0 grades of halogen-free flameproof
PP composite material, relative to there is halogen bromine antimony compound system, the density of V0 grades of flame-retardant polypropylene composite materials of Halogen has centainly
It reduces, but halogen-free flame retardants is mostly polarity, insufficient with nonpolar acrylic resin compatibility, there are precipitation risks；China
Patent CN201610192809 compounds V0 grades of flame-retardant polypropylenes of preparation with three oxidations, two ladder using eight bromine bis-phenol ethers or eight bromine bisphenol S ethers
Alkene composite material, relative to decabromodiphenylethane and the terraced compound system of three oxidation two, the additive amount phase of this eight bromines bis-phenol ethers type
To less, final V0 grades of flame-retardant polypropylene composite material density obtained are relatively low, but due to eight bromine bis-phenol ethers or eight bromines
Bisphenol S ether and polypropylene compatible are bad, can there are problems that precipitation by use for a long time, and the generation that problem is precipitated will be led
It causes the whiting of product surface bloom and Flame Retardancy can be decreased also.
Summary of the invention
To solve the problems in above-mentioned background technique, the present invention provides a kind of low-gravity V0 grades of polypropylene flame redardant composite woods
Material, the raw material composition including following parts by weight:
Further, the composite flame-retardant agent be haloflex, decabromodiphenylethane and metal hydroxides mixing and
At；The metal hydroxides includes the mixing of one or both of hydroxide magnesium hydroxide or aluminium hydroxide.
Further, in the composite flame-retardant agent, haloflex is 3-11 parts；Decabromodiphenylethane is 14-18 parts；Gold
Belonging to hydroxide is 5-10 parts.
Further, the grafting rate of chlorine is 35%-36% in the haloflex；
Polyethylene is grafted using chlorine, the anti-flammability of composite material can be further increased, and chlorinity is excessively high, again
Difficulty can be caused to the production and processing of haloflex, and the performance of composite material also can be unstable, therefore by chlorine in this programme
Content is limited to 35%-36%.
Further, the inflatable balloon is made of the shell of thermoplastic resin and the low boiling point hydrocarbon of Nei Bao；It is described swollen
Swollen bead is made of the kernel of packet calcium bicarbonate in the shell of thermoplastic resin, the thickness of the shell of the inflatable balloon with it is interior
The diameter ratio of core is 1:1-3:1；The shell is acrylic copolymer or acrylic acid series copolymer；
In the present solution, using the shell and Nei Bao calcium bicarbonate of thermoplastic resin as inflatable balloon；When heated, bicarbonate
Calcium carbon dioxide gas, while hollow volume is generated, can achieve the effect of expansion to increase volume reduces density, separately
Outer that serious burning once occurs, the carbon dioxide of release may also reach up fire-retardant effect.
Further, the toughener is mixed for one or both of ethylene-octene copolymer or ethylene-butene copolymer
It closes.
Further, described mineral-filled for one of talcum powder, barium sulfate, calcium carbonate, wollastonite or a variety of mixing.
Further, the antioxidant is in Hinered phenols antioxidant, sulphur ester antioxidant and sub- acid ester salt kind antioxidant
One or more mixing.
Further, the lubricant be N, N '-ethylene bis stearamide, polyethylene wax, polypropylene wax, calcium stearate,
One of zinc stearate and barium stearate or a variety of mixing.
The present invention also provides a kind of preparation methods of low-gravity V0 grades of flame-retardant polypropylene composite materials, comprising the following steps:
Step a, polypropylene, toughener, antimony oxide, antimony oxide, mineral-filled, swollen is weighed by weight percentage
Swollen bead, antioxidant, lubricant；
Step b, all materials in step a are added to progress high-speed stirred in high-speed mixer to be uniformly mixed, are obtained pre-
Mixing；
Step c, parallel double-screw extruder is added from main feeding hopper in the premix for obtaining step b, makes all components object
Material carries out shear melting blending extrusion in parallel double-screw extruder, and wherein double screw extruder processing temperature is 170-230
℃；
Step d, cooling, the dry, pelletizing by the material strip come out through parallel double-screw extruder mouth mold, obtains V0 grades of low-gravity
Flame-retardant polypropylene composite material.
The present invention provides low-gravity V0 grades of flame-retardant polypropylene composite material compared with prior art, has effect below
Fruit:
The present invention uses inflatable balloon because expanded by heating generates hollow volume, and utilizes the lesser haloflex of density
Fire retardant and the metal hydroxide combustion inhibitor compounding part substitution biggish decabromodiphenylethane fire retardant of density, it is same reaching
Under the premise of flame retardant property, low-gravity V0 grades of flame-retardant polypropylene composite material is made；And the antimony oxide and halogen system used
Fire retardant and with it is heated when will form halide SbX3With oxyhalide SbOX3, these halide in solid-state or can be volatilized into gas
State.When halide is in solid-state, it is covered on synthetic surfaces and can completely cuts off air and play fire retardation；Halide is volatilized into gaseous state
When the gas halide that can absorb heat cooling effect, while volatilize can play isolation air and absorb combustion reaction living radical,
To play the role of inhibiting combustion process；In addition, the fire retardant used in this patent and acrylic resin compatibility are good, because
Without there is precipitation.
Composite material provided by the invention provides more for household electrical appliance and field of electronics personnel when doing product design
More, more flexible light use selection, has important practical application value.
