preparation example Construction

[0033] On the other hand, the embodiment of the present invention also provides a method for preparing a modified coating, comprising the following steps:

[0034] T01: According to the ingredients contained in the modified coating according to the present invention and their contents, the raw materials of each ingredient are weighed respectively;

[0035] T02: Mix the zirconia, photosensitive resin, pentaerythritol triacrylate, aliphatic hydrocarbon solvent and ketone solvent, and then filter to obtain the modified coating.

[0036] The preparation method provided by the present invention has simple process and low cost. After the modified coating obtained by the preparation method is coated on the surface of the base film layer of the transparent cover film to form a film, the temperature resistance of the base film layer of the transparent cover film can be improved. properties, so that the base material is not easy to be precipitated and thermally deformed under high tempe...

Embodiment 1

[0080] A transparent cover film, comprising a second release protective film, an adhesive layer, a second modified coating, a PET substrate film layer, a first modified coating and a first release protective film arranged sequentially from bottom to top membrane.

[0081] Wherein, the first modified coating and the second modified coating are obtained by coating and drying the modified coating, and the modified coating includes: 25% zirconia; 15% photosensitive resin; 1% pentaerythritol triacrylate; Heptane 20%, methyl-2-pentanone 10%, 1-methoxy-2-propanone 14%, and cyclohexanone 15%.

Abstract

The invention belongs to the technical field of transparent flexible circuit boards, and in particular relates to a modified coating used on the surface of a transparent covering film, a preparation method thereof, and a modified coating. The modified coating comprises the following components in mass percentage: 20-30% of zirconia; 9-30% of photosensitive resin; 0.5-1% of pentaerythritol triacrylate; 10-20% of aliphatic hydrocarbon solvent; Solvent 30‑60%. After the above-mentioned modified coating is coated on the surface of the base film layer of the transparent cover film to form a film, the temperature resistance of the base film layer of the transparent cover film can be improved, so that the base material is difficult to separate out and thermally deformed under high temperature conditions; therefore The modified coating is used on the surface of the transparent cover film to avoid fogging and improve light transmittance.

Description

technical field [0001] The invention belongs to the technical field of transparent flexible circuit boards, and in particular relates to a modified coating used on the surface of a transparent covering film, a preparation method thereof, and a modified coating. Background technique [0002] A light emitting diode (Light Emitting Diode, LED) is a commonly used light emitting device, which releases energy and emits light through the recombination of electrons and holes, and is widely used in the field of lighting. LED transparent screen is a kind of LED display screen. The light source is LED lamp beads. Compared with the traditional LED display field, the main characteristics of LED transparent screen are high transmittance, light weight of the screen body, and the screen body can be seamless. Splicing, the size can be expanded infinitely in principle, the main installation is attached behind the glass curtain wall or behind the glass window, and the indoor installation is ou...
