Embodiment 1

[0019] Example 1: Dissolve 0.05 g of non-water-soluble nano-silver powder in 2 ml of toluene, add 8.7 g of magnesium stearate, mix evenly, add to 5000 g of PP resin slices, and stir evenly. After blow drying at 80°C for 5 hours, the antibacterial PP chips were obtained by twin-screw blending and extrusion granulation. The chips can be used directly to make plastic and fiber products.

Embodiment 2

[0020] Embodiment 2: Dissolve 0.25 g of non-water-soluble nano-silver powder in 4 ml of acetone, add 27 g of calcium stearate, 20 g of polyethylene wax, mix evenly, add to 5000 g of polypropylene resin slices, and stir evenly. After air-drying at 90°C for 3.5 hours, it was pelletized by twin-screw blending and extrusion to obtain antibacterial PP chips. The chips can be used directly to make plastic and fiber products.

Embodiment 3

[0021] Example 3: Dissolve 2 g of non-water-soluble nano-titanium dioxide powder in 10 ml of ethanol, add 40 g of aluminum stearate, and 10 g of oxidized polyethylene wax, mix evenly, add to 5000 g of PP resin slices, and stir evenly. After air-drying at 70°C for 6 hours, twin-screw blending and extrusion granulation was performed to obtain antibacterial PP chips. The chips can be used directly to make plastic and fiber products.

Abstract

The invention relates to a method for manufacturing functional resin chips, in particular to a method for preparing antibacterial chips used for manufacturing antibacterial fibers and plastics, which has the advantages of high dispersibility, low energy consumption and simple process. The method comprises the following steps of: 1) stirring and dispersing organic antibacterial agent powder at the concentration of 10-50,000ppm in 0.01 to 5 weight percent of dispersing agent; 2) selecting proper original resin chips, and fully stirring and mixing with blend obtained in the step 1); and 3) drying, and performing extrusion granulation by using a twin-screw extruder. The prepared chips can serve as antibacterial resin masterbatches and also can be directly used for manufacturing the antibacterial fibers and plastics.

Description

Technical field [0001] The invention relates to a method for manufacturing functional resin chips, in particular to a method for preparing antibacterial chips for manufacturing antibacterial fibers and plastics, which has the advantages of good dispersibility, low energy consumption and simple process. Background technique [0002] "Antibacterial" has become one of the most popular words in the 21st century, reflecting people's emphasis on hygiene and quality of life. The preparation of antibacterial materials, especially antibacterial plastics and fibers, is usually achieved by adding antibacterial agents. The antimicrobial efficacy of an antimicrobial agent is directly related to the efficacy of the product. At present, antimicrobial agents are mainly divided into three categories: inorganic, organic and natural antimicrobial agents. Organic antibacterial agents have strong immediate effects, but poor safety, poor chemical stability, and poor temperature resistance. They...
