Abstract
The invention discloses a flame retardant modified PTT polyester, which comprises the following components by mass: 75%-90% of PTT, 5%-15% of a composite flame retardant, 2%-6% of a toughening agent, 2%-4% of polyethylene glycol, 0.1%-0.5% of an antioxidant, and 0.1%-1% of a lubricant. The composite flame retardant is a compound of bisphenol A-bis(diphenyl phosphate) and polydimethylsiloxane in a mass ratio of 4:1. The toughening compatilizer is an ethylene-butyl acrylate-glycidyl methacrylate copolymer, and the weight percentage content of glycidyl methacrylate copolymer is 2%-6%. The flame retardant modified PTT polyester provided by the invention has excellent flame retardance and good impact strength, tensile strength, heat resistance and processing fluidity, etc., and the non-halogen flame retardance can reach the UL94 V-0 level performance requirements, thus greatly improving the application effect and application field of PTT polyester.
Description
Technical field
The present invention relates to technical field of polymer materials, specifically a kind of flame-retardant modified PTT polyester.
Background technology
Poly(Trimethylene Terephthalate) (PTT) is as a kind of new polyester macromolecular material of excellent combination property, the fields such as fiber, monofilament, polyester dyeing agent, film, thermoplastic engineering plastic and non-woven fabrics are widely used at present, especially in engineering plastics field, PTT has the high-performance of PET and the workability of PBT simultaneously, and its price is much lower compared with PBT, thus there is good practical value.But PTT is the same with other engineering plastics, there is the deficiency of poor fire, this will limit the range of application of PTT widely.
Summary of the invention
The object of the present invention is to provide the flame-retardant modified PTT polyester that a kind of flame retardant properties is good, mechanical property is strong and cost is low.
The technical solution adopted for the present invention to solve the technical problems is: a kind of flame-retardant modified PTT polyester, and its component by mass percent proportioning is: PTT 75% ~ 90%, composite flame-retardant agent 5% ~ 15%, toughner 2% ~ 6%, polyoxyethylene glycol 2% ~ 4%, oxidation inhibitor 0.1% ~ 0.5%, lubricant 0.1% ~ 1%.
Described PTT is the polytrimethylene terephthalate of limiting viscosity 0.7 ~ 1.2dL/g.
Described composite flame-retardant agent is dihydroxyphenyl propane-bis-(diphenyl phosphoester) (BDP) of mass ratio 4:1 and the compound of polydimethylsiloxane (PDMS).
Described toughness reinforcing compatilizer is Ethylene-butyl Acrylate-methacrylic Acid Glycerin Ester Copolymer (PTW), and the weight percent content of glycidyl methacrylate copolymer is 2% ~ 6%.
Described oxidation inhibitor is the Hinered phenols antioxidant 1010 of mass ratio 1:1 and the compound of phosphite ester kind antioxidant 168.
Described lubricant is pentaerythritol stearate.
The preparation method of above-mentioned a kind of flame-retardant modified PTT polyester 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 modified effect and good resistance to impact shock, tensile strength, thermotolerance and processing fluidity etc., and halogen-free flameproof can reach the performance requriements of UL94 V-0 level, substantially increase effect and the Application Areas of PTT polyester.
