Detailed Description
The following provides a specific embodiment of the nano-antibacterial plastic film in the invention with reference to the attached drawings, but it should be noted that: the described embodiments are not intended to limit the practice of the invention. All similar structures and similar variations thereof adopting the invention shall fall within the scope of the invention.
See fig. 1. The nano antibacterial plastic film comprises 3-10 parts of nano potassium hydrogen persulfate, 1-6 parts of plastic additive and 85-96 parts of polyethylene. In practice, polyvinyl chloride, polypropylene, polystyrene and other resin materials can be used to make the film instead of polyethylene. The nano potassium hydrogen persulfate is nano potassium hydrogen persulfate.
The nano potassium hydrogen persulfate accounts for 6 parts by weight, the plastic additive accounts for 2 parts by weight, and the polyethylene accounts for 92 parts by weight.
The nano potassium hydrogen persulfate accounts for 6 parts by weight, the plastic additive accounts for 6 parts by weight, and the polyethylene accounts for 88 parts by weight.
The plastic additive adopts silicone. The preparation of the nano antibacterial plastic film needs to add a proper amount of silicone plastic additive into the mixed raw materials, the silicone is used as the plastic additive, the dispersion is uniform, the dosage is small, the strength and the unique wear-resistant and scratch-resistant performance of the nano antibacterial film can be improved, the fluidity of the raw material masterbatch is improved in the processing process, the masterbatch is rapidly dispersed in molten plastic fluid, and the application process is simple and convenient. Reduces the processing energy consumption, prolongs the service life of processing machinery and ensures that the nano antibacterial plastic film has good stability.
A preparation method of a nano antibacterial plastic film comprises the steps of stirring and mixing 3-10 parts of nano potassium hydrogen persulfate, 1-6 parts of plastic auxiliary and 85-96 parts of polyethylene to form mixture master batch; adding the mixture master batch into a film making machine; heating and melting the mixture master batch; and (4) extruding. The prepared nano antibacterial plastic film has the bacteriostasis rates of 98.9 percent and 99.5 percent on various harmful bacteria such as escherichia coli, staphylococcus aureus and the like
The nano potassium hydrogen persulfate adopts powder.
The polyethylene is in a granular form.
The stirring and mixing time of 3-10 parts of nano potassium hydrogen persulfate and 1-6 parts of plastic auxiliary agent with 85-96 parts of polyethylene is ten minutes.
Stirring and mixing 6 parts of nano potassium hydrogen persulfate, 2 parts of plastic auxiliary agent and 92 parts of polyethylene to obtain mixture master batch; adding the mixture master batch into a film making machine; heating and melting the mixture master batch; and (4) extruding.
