Abstract

The invention discloses a masterbatch for PTT polyester and a preparation method thereof. The masterbatch for PTT polyester provided by the invention comprises the following components by mass: 10%-30% of PTT resin, 30%-50% of titanium dioxide, 10%-30% of a PSPPP flame retardant, 4%-8% of a light stabilizer, 1%-5% of a dispersing agent, and 0.5%-2% of an antioxidant. The PSPPP flame retardant is PSPPP, the light stabilizer is 2-hydroxy-4-methoxybenzophenone or 2-hydroxy-4-octyloxybenzophenone. The masterbatch for PTT polyester provided by the invention has advantages of good dispersion, stable color, uniform coloring, convenient use, good environmental protection effect, good ageing resistance, excellent flame retardancy, good machinability, and low cost, etc., and has good application effect and practical value in PTT polyester production.

Description

A kind of PTT Color concentrates for polyesters and preparation method thereof

Technical field

The present invention relates to technical field of polymer materials, specifically a kind of PTT Color concentrates for polyesters and preparation method thereof.

Background technology

Poly(Trimethylene Terephthalate) (referred to as PTT polyester) is generally by 1, ammediol and terephthalic acid or terephthalate polycondensation obtain, and are a kind of new polyesters after polyethylene terephthalate (PET) and polybutylene terephthalate (PBT).PTT polyester is more excellent than PET and PBT in mechanical characteristics, weathering resistance, heat-resistant aging and resistance to hydrolysis, and PTT polyester can be used as fiber and combines the pollution resistance of the flexibility of nylon, the fluffiness of acrylic fibers and terylene, there is better colour fastness than nylon simultaneously, avoid the shortcoming of acrylic fibers balling-up easy to wear, have again reasonable feel, elasticity inherently very well and can normal temperature dyeing.Due to the excellent properties of PTT polyester, it can be widely used in the every field such as dress material, decoration and engineering plastics, particularly in carpet applications.PTT polyester relates to various colorant, and PTT polyester is painted mostly is the dyeing of dispersion dye dye, and not only cost is high, and environment protecting is poor, and color and luster is unstable, and this will greatly limit the application of PTT polyester in every field.

Summary of the invention

The object of the present invention is to provide a kind of colour stable, uniform coloring, good dispersity, the PTT Color concentrates for polyesters that easy to use and environment protecting is good and preparation method thereof.

The technical solution adopted for the present invention to solve the technical problems is: a kind of PTT Color concentrates for polyesters, and its component by mass percent proportioning is: PTT resin 10% ~ 30%, titanium dioxide 30% ~ 50%, PSPPP fire retardant 10% ~ 30%, photostabilizer 4% ~ 8%, dispersion agent 1% ~ 5%, oxidation inhibitor 0.5% ~ 2%.

Described PTT resin is the Poly(Trimethylene Terephthalate) of limiting viscosity 0.7 ~ 0.9dL/g, relative density 1.30 ~ 1.35g/cm3.

Described PSPPP fire retardant is polyphenylene phosphonic acids sulfobenzide ester.

Described photostabilizer is ESCALOL 567 or Octabenzone.

Described dispersion agent is the one in calcium stearate, ethylene bis stearamide, pentaerythritol stearate, AClyn lower molecular weight ionomer.

Described oxidation inhibitor is the one in the compound of antioxidant 1010, antioxidant 1076, antioxidant 1010 or antioxidant 1076 and irgasfos 168.

The preparation method of above-mentioned a kind of PTT Color concentrates for polyesters is: take each component by weight ratio, and add respectively in high-speed mixer, make to stir 3 ~ 5 minutes together, evenly rear discharging to be mixed adds in twin screw extruder, at 180 DEG C ~ 260 DEG C temperature after melting mixing extruding pelletization, and through super-dry, packaging, obtain the present invention.

The invention has the beneficial effects as follows, the present invention has the advantages such as good dispersity, colour stable, uniform coloring, easy to use and environment protecting be good, and ageing-resistant performance is good, flame retardant resistance is excellent, processibility is good, and cost is low, uses and have good effect and practical value in PTT production of polyester.
