Abstract
The invention discloses an antibacterial masterbatch for PTT polyester and a preparation method thereof. The antibacterial masterbatch for PTT polyester comprises the following components by mass: 20%-70% of PTT polyester, 10%-20% of an antibacterial agent, 10%-20% of a toughening agent, 5%-10% of an ultraviolet stabilizer, 5%-40% of a modified filler, 0.5%-3% of an antioxidant, and 0.5%-5% of a dispersing agent. The antibacterial agent is silver ion antibacterial zeolite powder with the surface subjected to titanate coupling agent activation treatment and a particle size of less than 5micrometers. When applied to PTT production, the antibacterial masterbatch provided by the invention can have excellent antibacterial performance and anti-aging performance, also improves the strength, rigidity, impact resistance and heat resistance of the material, and reduces the production cost at the same time. The preparation process provided by the invention is simple, and is easy for popularization and application.
Description
Technical field
The present invention relates to technical field of polymer materials, specifically a kind of PTT polyester antibacterial matrices and preparation method thereof.
Background technology
Poly(Trimethylene Terephthalate) (being called for short PTT polyester) is by terephthalic acid and 1, the polyester that ammediol is polymerized and obtains, and there is good wear resistance, thermotolerance and chemical proofing, be widely used in the fields such as fiber, film and engineering plastics at present.But, there is poor toughness, low temperature brittleness is poor, heat-resistant stability is bad problem in unmodified PTT polyester, and along with the progress of society, over entering year, people require more and more higher to textiles health and security etc., the textiles having good anti-microbial property is subject to the favor of consumers in general day by day, thus also will day by day increase the demand with high performance antibacterial PTT polyester.
Summary of the invention
The object of the present invention is to provide a kind of have excellent impact resistance can and PTT polyester antibacterial matrices and preparation method thereof of resistance toheat.
The technical solution adopted for the present invention to solve the technical problems is: a kind of PTT polyester antibacterial matrices, and its component by mass percent proportioning is: PTT polyester 20% ~ 70%, antiseptic-germicide 10% ~ 20%, toughner 10% ~ 20%, ultra-violet stabilizer 5% ~ 10%, modified fillers therefor 5% ~ 40%, oxidation inhibitor 0.5% ~ 3%, dispersion agent 0.5% ~ 5%.
Described PTT polyester is the Poly(Trimethylene Terephthalate) of limiting viscosity 0.7 ~ 1.5dL/g.
Described antiseptic-germicide is that surface is through titanate coupling agent activation treatment and the particle diameter silver-ion antibiotic zeolite powder that is less than 5 μm.
Described toughner is the one in Methacrylate-butadiene-styrene, ethylene-acrylate copolymer, acrylonitrile-acrylic acid-styrol copolymer, acrylonitrile-butadiene-styrene copolymer, acrylonitrile ethylene styrene copolymer.
Described ultra-violet stabilizer is Benzotriazole Ultraviolet Stabilizer or benzophenone ultraviolet absorption agent.
Described modified fillers therefor is the one in the surperficial nano-calcium carbonate through silane coupler modified process, nano kaoline, process white, alkali-free short glass fiber.
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 preparation method of above-mentioned a kind of PTT polyester antibacterial matrices 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 ~ 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, to there is excellent anti-microbial property and anti-aging function, but also improve the intensity of material, rigidity, shock resistance and thermotolerance etc., reduce production cost simultaneously, preparation technology provided by the invention is simple, is easy to apply.
