Problems solved by technology

However, since plastic is a high-viscosity system at high temperature, nano-powders are extremely fine and easy to agglomerate, and are not easy to disperse into plastics in a high-viscosity state, which makes it difficult to play an effective role.

Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with specific preferred embodiments, and the specific implementation of the present invention can not be considered to be limited to these descriptions. For those of ordinary skill in the technical field of the present invention, without departing from the concept of the present invention, some simple deduction or replacement can also be made, which should be regarded as belonging to the protection scope of the present invention.

[0018] Implementation column 1

[0019] The steps of this embodiment are as follows:

[0020] S1 Disperse nano-zinc oxide in ethyl acetate solvent to form a mixed dispersion with a mass fraction of 20%, then add nano-zinc oxide 5% by weight dispersant BYK111, put it into a grinder, grind it through a high-speed grinder, and grind it to a particle size When the diameter is about 40nm, the grinding is stopped, and the material is discharged to obtain a nano-slurry w...

Abstract

The invention discloses a nano antibacterial masterbatch and a preparation method thereof. The nano antibacterial masterbatch is prepared from the following raw materials in parts by weight: 80-90 parts of carrier resin polyethylene terephthalate(PET), 5-10 parts of a nano inorganic antibacterial agent, 5-10 parts of a dispersant, and 1-2 parts of an antioxidant. A nano oxide and the dispersant are dissolved in an organic solvent to prepare a mixed dispersion agent with the mass concentration of 10%-30%, the mixed dispersion agent is put into a grinder, and then nano slurry is prepared by grinding; and the obtained nano slurry, the antioxidant and the PET resin are added into a high-speed mixer and stirred for 15-20 minutes, and then a material is discharged and added into a twin-screw extruder for extrusion and granulation. The nano antibacterial masterbatch can be used for being added to various products such as textiles, and packaging bags, and the obtained product has the characteristics of good antibacterial effects, long validity period, and less influence on light transmittance.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a nano antibacterial masterbatch and a manufacturing method thereof. Background technique [0002] At present, plastic products play a very important role in people's daily life and industrial and agricultural production. As people's living standards are getting higher and higher, people's demand for plastics with antibacterial functions is also increasing. In order to make plastic products more widely used, people often add antibacterial agents to the plastic masterbatches for preparing plastic products. Thereby obtaining an antibacterial plastic product. Antimicrobial agents used in antimicrobial plastics can be classified as inorganic and organic. Organic antibacterial agents have poor toxicological safety, poor chemical stability and easy precipitation, etc., and can cause drug resistance of microorganisms. Inorganic antibacterial agents are widely used because o...
