Abstract
The invention discloses an environmental-protection halogen-free flame retardation blending modified PTT polyester composition. The PTT polyester composition comprises the following ingredients, by weight, 80%-90% of PTT, 3%-8% of polysulfonyldiphenylene phenyl phosphonate, 2%-5% of polydimethylsiloxane, 2%-5% of polyethylene glycol, 0.5%-1% of phenyl glycidyl ether, 0.1%-0.5% of anti-oxidants and 0.1%-1% of pentaerythritol stearate. The beneficial effects are that the PTT polyester composition has excellent flame retardation performance, and meets halogen-free, good environmental protection and UL94-0 level flame retardation requirements; the heat stability is good, the cost is low, and usage requirements of associated aspects can be met well.
Description
Technical field
The present invention relates to technical field of polymer materials, specifically a kind of PTT polymer blend of feature of environmental protection halogen-free flameproof blending and modifying.
Background technology
Poly(Trimethylene Terephthalate) (PTT) is as a kind of new polyester macromolecular material of excellent combination property, the fields such as fiber, film, engineering plastics are widely used at present, but unmodified PTT exists the defect of poor fire, this will limit its range of application greatly.
Summary of the invention
The object of the present invention is to provide the PTT polymer blend of the low and preparation technology's simple feature of environmental protection halogen-free flameproof blending and modifying of a kind of good flame retardation effect, cost.
The technical solution adopted for the present invention to solve the technical problems is: the PTT polymer blend of feature of environmental protection halogen-free flameproof blending and modifying, and its component by mass percent proportioning is: PTT 80% ~ 90%, polyphenylene phosphonic acids sulfobenzide ester 3% ~ 8%, polydimethylsiloxane 2% ~ 5%, polyoxyethylene glycol 2% ~ 5%, phenyl glycidyl ether 0.5% ~ 1%, oxidation inhibitor 0.1% ~ 0.5%, pentaerythritol stearate 0.1% ~ 1%.
Described PTT is the Poly(Trimethylene Terephthalate) of limiting viscosity 0.7 ~ 1.5dL/g.
Described oxidation inhibitor is the one in the compound of antioxidant 1010, antioxidant 1076, antioxidant 1010 or antioxidant 1076 and irgasfos 168 1:1 in mass ratio.
The preparation method of the PTT polymer blend of above-mentioned feature of environmental protection halogen-free flameproof blending and modifying is: take each component by weight ratio, and add respectively in high-speed mixer, make to stir 3 ~ 10 minutes together, evenly rear discharging to be mixed adds in twin screw extruder, extrude through melting mixing at 180 DEG C ~ 260 DEG C temperature, cooling granulation, drying, namely obtain the present invention.
The invention has the beneficial effects as follows, the present invention has excellent flame retardant properties, meets Halogen, the feature of environmental protection is good and reach UL94 V-0 level flame-retardancy requirements, and Heat stability is good, and cost is low, can meet the service requirements of the parties concerned well.
