Problems solved by technology

[0005] But existing urethane acrylate UV photocurable resin still has the following technical problems when protecting the silver nanowire conductive film: one, when the film thickness of 100-500nm, in water resistance, bending resistance, surface hardness 1. The solvent resistance performance still cannot meet the demand; 2. When the photosensitive material containing silver nanowires is contained, the main body of the resin will react with the silver nanowires to cause damage to the conductive function of the silver nanowires

Embodiment 1～7

[0040] The raw materials of each embodiment UV photocurable resin are as shown in Table 1, and the preparation method is as follows:

[0041] Weigh each raw material according to the ratio; first add solvent to urethane acrylate, stir mechanically for 20 minutes, then add active monomer, silver stabilizer and graphene quantum dots while stirring, continue stirring for 20 minutes, then add ATO, ultrasonically disperse for 30 minutes, get the mixture;

[0042] The silver nanowire transparent conductive ink is coated on the PET substrate to form a conductive layer to obtain a silver nanowire conductive film.

[0043] Add a photoinitiator to the mixture and stir evenly to obtain a UV photocurable resin; then use a dimple coater to uniformly coat the UV photocurable resin (coating speed is 20m / min) on the silver nanowire conductive film, Then cured by UV light (using UVLED lamp, curing energy 800mJ / cm 2 ) to form a UV protective film layer.

Embodiment 8

[0045] For comparison, the same formula and method as in Example 1 were used to obtain UV photocurable resin and form a UV protective film layer, the only difference being that the polyurethane acrylic resin of Example 1 was replaced by CN2920 with CN104NS epoxy acrylate.

Abstract

The invention discloses UV light-cured resin applied to a silver nanowire conductive film and a preparation method of the UV light-cured resin. The UV light-cured resin is prepared from the raw materials: polyurethane acrylate, active monomers, a solvent, a light initiator, a silver stabilizer, graphene quantum dots and ATO. Compared with the existing polyurethane acrylate UV light-cured resin, the UV light-cured resin provided by the invention is greatly improved in the aspects of water resistance, bending resistance, surface hardness and solvent resistance, and is more suitable for the silver nanowire conductive film.

Description

technical field [0001] The invention relates to a UV photocurable resin, in particular to a UV photocurable resin applied to a silver nanowire conductive film. Background technique [0002] The main conductive functional material of the silver nanowire conductive film is silver nanowire. Silver nanowire is a highly active nanomaterial that is easily photocatalyzed, and it is easy to interact with organic matter, oxidizing atmosphere, water, light, etc. to produce property changes and affect the original properties. The silver nanowire conductive film is easily denatured by moisture, oxygen, and trace sulfides contained in the air during storage at room temperature, resulting in loss of electrical conductivity, which in turn leads to functional damage of the applied product. Therefore, existing products need to carry out protection research on the stability of silver nanowires. [0003] At present, there are few researches on the protection of silver nanowire conductive fil...
