Description
Technical Field
The invention relates to the field of PE (polyethylene) films, in particular to a high-barrier antibacterial PE film and a preparation method thereof.
Background
The PE protective film is a macromolecular organic compound with the simplest structure, and is a macromolecular material which is widely applied in the world nowadays. The PE protective film uses a special Polyethylene (PE) plastic film as a base material, and is classified into a high density polyethylene protective film, a medium density polyethylene, and a low density polyethylene according to the difference in density.
This application improves under prior art, and among the prior art, the PE membrane waterproof performance that generally makes is relatively poor, and water stain falls on the surface can permeate inside to cause the corruption, do not carry out its technology of effectual improvement in the antibacterial property to PE membrane body during the time of the while prior art, lead to the later stage to breed the bacterial easily, influence antibacterial property.
Disclosure of Invention
The invention aims to solve the defects in the prior art and provides a high-barrier antibacterial PE film and a preparation method thereof.
In order to achieve the purpose, the invention adopts the following technical scheme:
the high-barrier antibacterial PE film comprises a high-barrier film and an antibacterial PE film, wherein the raw material of the high-barrier film is PVDC resin, and the antibacterial PE film is prepared from the following raw materials in parts by weight: 110-140 parts of PE resin, 20-30 parts of polyurethane acrylic resin, 15-20 parts of a composite antibacterial agent, 10-13 parts of benzoyl peroxide, 8-12 parts of a plasticizer, 15-20 parts of a preservative, 10-15 parts of a film forming agent, 8-12 parts of a stabilizer, 1-3 parts of glycerol, 0.4-0.6 part of an antioxidant, 10-15 parts of silver nitrate and 0.5-1 part of a silver-copper alloy substance.
As a further scheme of the invention: the composite antibacterial agent is vanillin, the plasticizer is one or more of sorbitol, fructose, polyethylene glycol and tributyl citrate, the preservative is one or more of deoxyacetic acid, sodium diacetate and sorbic acid, and the film forming agent is one or more of propylene glycol butyl ether, benzyl alcohol and hexylene glycol butyl ether acetate.
A preparation method of a high-barrier antibacterial PE film comprises the following steps:
s1: adding the composite antibacterial agent, the plasticizer, the preservative, the film forming agent, the glycerol and the antioxidant into a stirrer, and heating and stirring to prepare a first mixed solution;
s2: adding silver-copper alloy substances and silver nitrate into a benzene fatty alcohol solvent for dispersion, and adding polyurethane acrylic resin into the benzene fatty alcohol solvent for mixing after the dispersion is finished to obtain a second mixed solution;
s3: adding a film forming agent and a stabilizing agent into the second mixed solution in the step S2, and stirring and mixing to obtain an antibacterial solution;
s4: adding the first mixed solution obtained in the step S1, the antibacterial solution obtained in the step S3 and the PVDC resin into a dispersing machine, carrying out high-speed dispersion, and uniformly dispersing to obtain a mixture;
s5: and adding the mixture into an extruder for melting and plasticizing, and performing inflation and cooling molding by compressed air to obtain the high-barrier antibacterial PE film.
As a further scheme of the invention: in the step S1, the heating temperature is 50-90 ℃, the rotating speed is 1400-1600 r/min, and the stirring time is 3.5-6 h.
As a further scheme of the invention: the rotating speed of the disperser in the step S4 is 1400r/min-1600r/min, and the dispersing time is 1.5h-3h.
