Problems solved by technology

The silver salt is immobilized in the protective film, and its release rate is similar to that of the isothiazolinone compound in the previous scheme, which cannot be precisely controlled, so it cannot achieve a durable antibacterial effect. In order to uniformly coat the mixed solution containing the powder On the surface of the protective film and to ensure the amount of coating, the mixed solution needs to be diluted to a certain range, the proportion of silver powder is relatively large, the distribution in the mixed solution is uneven, and some silver powders will fall off.
The general solution is to load it on a carrier with better dispersion, or coat the coupling agent on the surface of the silver powder, but the loaded material will affect the light transmittance of the protective film to varying degrees.

Embodiment 1

[0031] Example 1 is to prepare nano-silver structure solution: dissolve 0.1mol of silver nitrate and 0.08mol of polyvinylpyrrolidone in 22mol of ethylene glycol, stir at room temperature for 10min, heat up to 150°C, and keep warm for 30min to prepare nano-silver structure solution. Nano-silver structure solution of silver wire;

[0032] Specifically, the silver salt may include silver nitrate, silver trifluoromethanesulfonate, fatty acid silver salt (silver acetate), aromatic carboxylic acid silver salt or triazole organic silver salt.

[0033] The stabilizer is an organic polymer stabilizer, such as polyvinylpyrrolidone, polyethylene glycol, polyvinyl alcohol; it can also be a small molecule surfactant, such as oleic acid, cetyltrimethylammonium bromide, lauryl Sodium alkylsulfate, sodium dodecylbenzenesulfonate; it can also be the mixture of the above-mentioned organic polymer stabilizer and small molecule surfactant.

[0034] Polyols have dual functions as reactants and solv...

Embodiment 2

[0036] The difference between Example 2 and Example 1 is that the raw materials of the preparation method of Example 2 also include 0.0005 mol of imidazole-type ionic liquid, and the imidazole-type ionic liquid is added to ethylene glycol together with silver nitrate and polyvinylpyrrolidone. The imidazole-type ionic liquid is 1-methylimidazolium-3-propylsulfonate.

[0037] Imidazole-type ionic liquids equivalent to 1-methylimidazole-3-propylsulfonate can also choose 1-methylimidazole-3-butylsulfonate, 1-n-butyl-3-methylimidazole tetra Fluoroborate, 1-alkyl-3-methylimidazole bromide, N-methylimidazole p-toluenesulfonate.

Embodiment 3

[0039] The difference between Example 3 and Example 2 is that the composition of reactants in S1 is 0.1 mol of silver nitrate, 0.1 mol of polyvinylpyrrolidone, 20 mol of ethylene glycol, and 0.001 mol of imidazole-type ionic liquid.

Abstract

The invention discloses an antibiosis protection film making method. The method comprises the steps of preparing a nanometer silver structure solution, preparing a light-cured adhesive, coating, and light-curing. In the invention, the nanometer silver structure solution in a one-step manner through adopting a reducing technology, and the structure solution is directly mixed with an ultraviolet light cured oligomer and an initiator to prepare the light-cured adhesive, so separation of nanowires and a reduction reaction solution, easy entwisting of silver nanowires in the centrifuging and washing processes and ultrasonic dispersion and other intermediate pretreatments of the light-cured adhesive with a large viscosity are avoided. The method has the advantages of operation simplification, few processes, short process route, avoiding of oxidation of the surface of nanosiver in drying and other treatment processes, and guaranteeing of the sterilization performance of the silver nanowires. The invention also discloses an antibiosis protection film with excellent flatness and light transmittance.

Description

technical field [0001] The invention relates to the technical field of protective film materials, in particular to a preparation method of an antibacterial protective film and the antibacterial protective film. Background technique [0002] With the increasing popularity of smart terminal devices, electronic devices with display screens are used more and more frequently in daily life. In order to avoid damage to the display screen of electronic equipment due to bumping or scratching, people usually stick a protective film on the surface of the display screen. , the above solution well solves the shortcoming that the display screen is easy to be scratched. However, studies in recent years have found that the high frequency of use of electronic products will inevitably adhere to bacteria, especially some bacteria are infectious and pathogenic, such as Staphylococcus aureus; electronic equipment cannot be cleaned, and long-term accumulation will only Make the bacteria accumul...
