Described PTT resin is the Poly(Trimethylene Terephthalate) of limiting viscosity 0.7 ~ 1.5dL/g.
Described fire retardant is the compound of the polyphenylene phosphonic acids sulfobenzide ester of mass ratio 4:2:1, polydimethylsiloxane and nano-sized magnesium hydroxide.
Described static inhibitor is the one in two (2-hydroxyethyl) octyl methyl biconjugate ammonium tosylate, polyethylene oxide, polyether ester amides, polyether ester imide, stearic acid monoglycerides, Nanometer-sized Antimony-doped stannic oxide.
Described MBS properties-correcting agent is the styrene-butadiene-methyl acrylic ester terpolymers with nucleocapsid structure.
Described photostabilizer is the compound of hindered amines high molecular photostabilizer GW-944Z and the GW-622 of mass ratio 1:1.
Described oxidation inhibitor is the one in the compound of antioxidant 1010, antioxidant 1076, antioxidant 1010 or antioxidant 1076 and irgasfos 168.
Described dispersion agent is the one in calcium stearate, ultra-fine TAS-2A powder, modification ethylene bis-fatty acid amides.
The preparation method of above-mentioned PTT Flame-retardant antistatic master batch is: take each component by weight ratio, and add respectively in high-speed mixer, make to stir 3 ~ 15 minutes together, evenly rear discharging to be mixed adds in twin screw extruder, at 180 DEG C ~ 260 DEG C temperature through melting mixing, extrude, cool, granulation, and dry rear packaging, obtain the present invention.
The invention has the beneficial effects as follows, the present invention is when being applied to PTT and producing, and will have excellent halogen-free flameproof, toughness reinforcing and antistatic modified effect, and processibility is good, easy to use, cost is low, strong adaptability, and preparation technology is simple.
