Embodiment 1

[0025] An antibacterial masterbatch, comprising the following raw materials in parts by weight: 70 parts by weight of polypropylene resin, 3 parts by weight of graphene loaded with nano-silver, 1 part by weight of polyvinylpyrrolidone, and 0.4 parts by weight of calcium stearate. The preparation process of the antibacterial masterbatch is as follows: Weigh the raw materials in various parts by weight, add them into a high-speed mixer to fully mix them evenly, and then melt and extrude the mixture through a twin-screw extruder at high temperature to obtain antibacterial masterbatches. Set the process parameters of the twin-screw extruder. The temperatures in each zone from the feeding port to the outlet of the machine head are 175-185°C, 195-210°C, 195-210°C, 185-200°C, and 200-210°C. Antibacterial masterbatches can be prepared by melt granulation within the temperature range. The specific process parameters of the twin-screw extruder in this example are set as follows: the tem...

Abstract

The invention relates to the field of high polymer materials, and provides an antibacterial master batch, which comprises the following raw materials in parts by weight: 70-90 parts of polypropylene resin, 3-6 parts of nano-silver loaded graphene, 1-3 parts of a dispersing agent and 0.4-0.8 part of a lubricating agent, wherein the nano-silver loaded graphene has the advantages of both graphene andnano-silver. The antibacterial master batch obtained after melt granulation with polypropylene resin has excellent antibacterial property, solves the problems that a product produced from a polypropylene material in the prior art does not have antibacterial property and is easily polluted by bacteria, and can be applied to production of disposable tableware.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to an antibacterial masterbatch and its application. Background technique [0002] Polypropylene is a crystalline polymer with a regular structure. It has the advantages of non-toxicity, light weight, good mechanical properties, corrosion resistance, easy processing and recycling, and is widely used in daily life, such as kitchen utensils, bathroom facilities, Garbage bins, plastic casings of household appliances, wallpapers, food packaging bags, etc. However, as people's awareness of health and environmental protection becomes stronger and stronger, the polypropylene material itself can no longer meet people's needs, so it needs to be modified to endow it with other special properties, such as flame retardancy and antistatic properties. , flexibility and so on. Modification methods include chemical modification and physical modification. The so-called chemical modification refers...
