Problems solved by technology

[0004] In the prior art, antibacterial agents are added during the preparation of polyesters such as esterification and polymerization to obtain fibers with antibacterial effects. For example, patent application CN102031585A discloses a preparation method for antibacterial polyester filaments. In the synthesis of polyterephthalic acid In the process of ethylene glycol ester, nano-sized zirconium phosphate silver-loaded antibacterial substances are added, but compared with the production of antibacterial polyester fibers by the masterbatch method, this method requires additional polymerization equipment, and the production method is not flexible enough to meet the market demand for small batch production.

Embodiment 1

[0027] Weigh the components according to Table 1, add them to the drum mixer, mix for 15-20 minutes at room temperature, and then add the evenly mixed materials to the twin-screw extruder to melt and blend. The selected screw is divided into 10 zones, each zone The temperature is 180°C, 200°C, 230°C, 250°C, 250°C, 260°C, 260°C, 260°C, 260°C, 250°C, the screw speed is 100 rpm, and two filter screens are installed in front of the screw extruder. The mesh number of the filter screen is 200, and the meshes of the filter screen are arranged crosswise to improve the filtration accuracy. The silver of the present invention is obtained by shearing and mixing with a twin-screw extruder, then extruding, cooling, pelletizing, and packaging. It is an antibacterial polyester masterbatch.

[0028] The obtained silver-based antibacterial polyester masterbatch has an appearance of white cylindrical particles with uniform size, a particle size of about 3mm*3mm, a melting point of 228°C, heat resi...

Embodiment 2

[0033] Weigh the components according to Table 1, add them to the drum mixer, mix for 15-20 minutes at room temperature, and then add the evenly mixed materials to the twin-screw extruder for melt blending. The selected screw is divided into 11 zones, each zone The temperature is 180°C, 200°C, 230°C, 250°C, 250°C, 260°C, 260°C, 260°C, 260°C, 250°C, 250°C, the screw speed is 150 revolutions per minute, and two pieces are installed before the screw extrusion port Filter, the mesh number of the filter is 230, and the mesh of the filter is arranged in a cross pattern to improve the filtration accuracy. It is cut and mixed by a twin-screw extruder, then extruded, cooled, pelletized, and packaged. Invented silver antibacterial polyester masterbatch.

[0034] The resulting silver-based antibacterial polyester masterbatch is white in appearance, with a particle size of about 3mm*3mm, a melting point of 228.5°C, heat resistance, an intrinsic viscosity of 0.73dl / g, and a filtration pressur...

Abstract

The invention relates to a silver antibacterial polyester masterbatch and a preparation method thereof. The silver antibacterial polyester masterbatch is prepared from the following components in parts by weight: 78-88 parts of a resin carrier, 10-20 parts of an antibacterial agent, 1-2 parts of a dispersant, 0.3-0.4 part of an antioxidant and 0.5-1 part of a stabilizer. The silver antibacterial polyester masterbatch is has the advantages of low in production cost and high in spinnability, can be used for spinning polyester filaments; the prepared polyester filament products are stable in quality and excellent in antibacterial property.

Description

Technical field [0001] The invention relates to the technical field of functional polymer materials, in particular to a silver-based antibacterial polyester master batch and a preparation method thereof. Background technique [0002] Polyester is the general term for a class of polymers obtained by polycondensation of polyols and polyacids, mainly refers to polyethylene terephthalate (PET), which can be made into polyester fibers and polyester films. PET fiber (trade name polyester) has excellent performance and easy-to-obtain raw materials. It is a synthetic fiber with the highest output among synthetic fibers. It has a wide range of uses and can be used to make clothing, curtains, bedding, and interior decoration. With the development of economy and the progress of science and technology, people pay more and more attention to the health care function of clothing. Antibacterial PET fiber can be used to make antibacterial socks, sportswear and other clothing, bedding and sanitar...
