Abstract
The invention discloses an anti-microbial enhanced smooth master batch for PTT polyesters. The anti-microbial enhanced smooth master batch comprises the following ingredients, by weight, 20%-60% of PTT polyesters, 2%-10% of silicon dioxide, 5%-15% of erucyl amide, 10%-30% of modified wollastonite, 8%-20% of MBS, 10%-20% of antibacterial agents, 4%-8% of ultraviolet ray stabilizing agents, 0.1%-2% of anti-oxidants and 0.5%-5% of dispersants. The beneficial effects are that When the anti-microbial enhanced smooth master batch is used in the PTT production, good smoothing function and anti-microbial performance are achieved, the intensity, the rigidity, the impact resistance, the heat resistance and the like of materials are raised, the production cost is lowered, the production efficiency is raised, and therefore the anti-microbial enhanced smooth master batch has good practical effects and application prospects.
Description
Technical field
The present invention relates to technical field of polymer materials, specifically a kind of PTT polyester smooth master batch of antibacterial enhancing.
Background technology
Poly(Trimethylene Terephthalate) (being called for short PTT polyester) is by terephthalic acid and 1, ammediol polycondensation and obtained is a kind of new polyester macromolecular material having development prospect of new research and development after polyethylene terephthalate (PET) and polybutylene terephthalate (PBT).Compared with PET, PBT, PTT polyester has the multiple good characteristics such as snappiness, good continuous printing and dyeing characteristic, uvioresistant, anti-internal stress, low electrostatic and good biological degradability, reusable edible.In addition, PTT polyester processibility is good, water absorbability is little, dimensional stability is high, physical property change is little, has the high-performance of PET and the workability energy of PBT concurrently.Therefore PTT polyester is very wide in various fields application prospects such as carpet industry, dress materials, engineering plastics, films.But PTT polyester is used alone but exists the problem that poor toughness, smoothness are not high, thermotolerance is bad, this will greatly limit its application in film applications; Meanwhile, along with the raising of people's living standard, the demand of antibacterial PTT polyester is also increased day by day.
Summary of the invention
The object of the present invention is to provide the smooth master batch of the antibacterial enhancing of PTT polyester that a kind of mechanical property is good, easy to use, cost is low.
The technical solution adopted for the present invention to solve the technical problems is: the PTT polyester smooth master batch of antibacterial enhancing, and its component by mass percent proportioning is: PTT polyester 20% ~ 60%, silicon-dioxide 2% ~ 10%, erucicamide 5% ~ 15%, modified grammite 10% ~ 30%, MBS 8% ~ 20%, antiseptic-germicide 10% ~ 20%, ultra-violet stabilizer 4% ~ 8%, oxidation inhibitor 0.1% ~ 2%, dispersion agent 0.5% ~ 5%.
Described PTT polyester is the Poly(Trimethylene Terephthalate) of limiting viscosity 0.7 ~ 1.5dL/g.
Described silicon-dioxide be surface through titanate coupling agent activation treatment and particle diameter at the aerosil nanoparticle of 20 ~ 40nm.
Described modified grammite be surface through silane coupler modified process and diameter 3 ~ 30 μm, length is at 10 ~ 500 μm and the fibrous wollastonite of length-to-diameter ratio in 3 ~ 100 scopes.
Described MBS is the Methacrylate-butadiene-styrene with nucleocapsid structure.
Described antiseptic-germicide is the one in silver ions phosphoric acid salt, silver-ion antibiotic zeolite, silica modified organic antibacterial agent, phenol antiseptic-germicide, quaternary alkylphosphonium salt antiseptic-germicide.
Described ultra-violet stabilizer is Benzotriazole Ultraviolet Stabilizer or benzophenone ultraviolet absorption agent.
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, pentaerythritol stearate, modification ethylene bis-fatty acid amides.
The above-mentioned PTT polyester preparation method of the smooth master batch of antibacterial enhancing is: take each component by weight ratio, and add respectively in the high-speed mixer of 3000 ~ 6000r/min, make to stir 5 ~ 45 minutes together, evenly rear discharging to be mixed adds in twin screw extruder, at 180 DEG C ~ 280 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, to there is good smooth function and anti-microbial property, but also improve the intensity of material, rigidity, shock resistance and thermotolerance etc., reduce production cost simultaneously, improve production efficiency, thus there is good practical function and application prospect.
