Problems solved by technology

However, this method only uses a bacteriostatic agent on the UV light-cured wear-resistant layer, and does not solve the problem of bacteriostasis of the installed adhesive layer. The effective period of bacteriostasis is short and the bacteriostasis efficiency in a humid environment is limited, which limits this Application range of explosion-proof film

[0047] The present invention also provides a method for preparing a glass explosion-proof film with antibacterial and antifungal effects, comprising the following steps:

[0048] (1) Preparation of UV photocurable coating composition:

[0049] According to the mass ratio mentioned above, take antibacterial and mildew-proof oligomer resin, wear-resistant UV oligomer resin, trimethylolpropane triacrylate, photoinitiator 184, wetting and leveling agent, ethyl acetate, in Disperse and stir evenly in a light-proof container to obtain a UV light-curable coating composition.

[0050] Among them, as a preferred solution of the preparation method of the glass explosion-proof film of the present invention, the antibacterial and antifungal oligomer resin is polyhexamethylene guanidine hydrochloride (PHMG) and methacrylic acid. Methylguanidine hydrochloride dimethylacrylamide oligomer resin (PHMG-MAA), the specific preparation method of the PHMG-MAA can be: polyhexamethyleneguanidine hyd...

Embodiment 1

[0065] A preparation method of a glass explosion-proof film with antibacterial and mildewproof effects, comprising the following steps:

[0066] (1) Preparation of antibacterial and mildew-proof oligomer resin:

[0067] Mix and feed polyhexamethyleneguanidine hydrochloride and methacrylic acid at a molar ratio of 1:2.01, add them into a 500ml four-neck flask, and control the temperature at 80±5°C, such as 75°C, 80°C, 85°C , adding boron trifluoride ether with a mass ratio of 0.01% as a catalyst, stirring for 6 hours, vacuumizing to remove small molecular substances generated in the condensation reaction, cooling to room temperature, adding ethyl acetate to dilute to a solid content of 50%, and synthesizing polyhexa Methylene guanidine hydrochloride dimethylacrylamide to obtain an antibacterial and antifungal oligomer resin.

Abstract

The invention relates to a glass explosion-proof film with antibacterial and antimildew effects, which includes a PET protective film from the outside to the inside, a UV light-cured coating, a PET pre-coated film, an anti-mildew resin installation adhesive layer and a PET release film, UV light The main raw materials of the cured coating and their mass parts are: 10-15 parts of antibacterial and anti-mildew oligomer resin, 25-28 parts of wear-resistant UV oligomer resin, 4-7 parts of trimethylolpropane triacrylate, light 1844-6 parts of initiator, 0.3-0.5 parts of wetting and leveling agent, 50 parts of ethyl acetate; the main raw materials and parts by mass of anti-mold resin installation adhesive layer are: 10-20 parts of PHMG‑PUA, 10 parts of butyl acrylate ~15 parts, 8~14 parts of isooctyl methacrylate, 5~10 parts of diacetone acrylamide, 3~5 parts of azobisisobutyronitrile, 50 parts of ethyl acetate. Compared with the traditional anti-explosion film, the anti-bacterial and mildew-proof effect is durable, and the effective rate of inhibiting and killing Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus reaches more than 96%. At the same time, the invention also provides a A method for preparing a glass explosion-proof film with antibacterial and antifungal effects.

Description

technical field [0001] The invention relates to the technical field of glass films, in particular to a glass explosion-proof film with antibacterial and anti-mold effects and a preparation method thereof.
