Embodiment 1

[0062] A method for preparing paper luminescence based on a full printing process, which is specifically implemented according to the following steps:

[0063] Finishing the paper:

[0064] (1) Generally, uncoated paper (uncoated on the surface) is selected as the base material of the device, and 80 g / m is selected in this embodiment. 2 copy paper. With low concentration (5%) fine ground ground calcium carbonate paint (90% of the ground calcium carbonate particle size is less than 2μm), the paper surface is filled by rod coating to form a filling layer on the surface, filling the paper surface. The pore structure was dried in an oven at 90 °C for 1 h, and the surface of the paper was smooth to form a filling layer on the surface.

[0065] (2) On the basis of the above, the kaolin coating of the sheet-like structure is coated by bar coating, and the coating amount is 9g / m 2 , After the coating is completed, it is dried in an oven at 90° C. for 1 h, and the surface roughness ...

Embodiment 2

[0077] A method for preparing paper luminescence based on an all-printing process, specifically implemented according to the following steps:

[0078] Surface modification of paper:

[0079] (1) Generally, uncoated paper (surface uncoated) is selected as the base material of the device, and what this embodiment selects is 80g / m 2 copy paper. Use low concentration (5%) finely ground ground calcium carbonate paint (90% of the particle size of the ground calcium carbonate is less than 2 μm) to fill the surface of the paper by rod coating to form a filling layer on the surface and fill the surface of the paper. Pore ​​structure, dry in an oven at 100°C for 1 hour, the surface of the paper surface will be flat, forming a filling layer on the surface.

[0080] (2) On the basis of the above, adopt the method of bar coating to coat the kaolin coating with flake structure, and the coating amount is 10g / m 2 , after the coating was completed, it was dried in an oven at 100° C. for 1 h...

Embodiment 3

[0091] A method for preparing paper luminescence based on an all-printing process, specifically implemented according to the following steps:

[0092] Surface modification of paper:

[0093] (1) Generally, uncoated paper (surface uncoated) is selected as the base material of the device, and what this embodiment selects is 80g / m 2 copy paper. Use low concentration (5%) finely ground ground calcium carbonate paint (90% of the particle size of the ground calcium carbonate is less than 2 μm) to fill the surface of the paper by rod coating to form a filling layer on the surface and fill the surface of the paper. Pore ​​structure, dry in an oven at 80°C for 1 hour, the surface of the paper surface will be flat, forming a filling layer on the surface.

[0094] (2) On the basis of the above, adopt the method of bar coating to coat the kaolin coating with flake structure, and the coating amount is 8g / m 2 , After the coating is completed, dry in an oven at 80°C for 1 hour, the surfac...

Abstract

The invention discloses a paper luminescent structure and a preparation method based on a full printing process, which relates to a material used for each functional layer of paper luminescent, a printing method and a treatment method of paper. The printing methods used include screen printing and ink-jet printing. Treatment of paper includes: fill layer, improvement layer, barrier layer, paper coating, printing varnish layer, which are used to adjust the surface roughness and porosity of paper. The paper light-emitting structure functional layer provided by the invention has the following layers from bottom to top: a paper substrate, a filling layer, an improvement layer, a barrier layer, a paper surface coating layer, a printing light oil layer, a conductive anode layer, a hole transportlayer, a light-emitting layer, an electron injection layer and a conductive cathode layer. The invention is used for realizing the patterning of luminescence on wrapping paper, and provides technicalsupport for the application of the technology in printing intelligent packaging products in the future.

Description

technical field [0001] The invention relates to the fields of paper, printing and paper-based materials, and relates to a preparation method of an organic light-emitting structure of paper, in particular to a paper light-emitting structure and a preparation method based on a full printing process. Background technique [0002] Electro-organic light-emitting devices have unique advantages such as planar auto-luminescence, fast response, wide viewing angle, thin and light volume, and the ability to fabricate bendable, rollable and even foldable devices, and are known as the most promising next-generation light-emitting and display technologies. At present, some electro-organic light-emitting devices have been successfully used in mobile phones, tablet computers, TVs, wearable devices, etc. In the preparation of existing organic light-emitting devices, the choice of substrates is basically based on glass substrates, or polyethylene terephthalate (PET), polyethylene naphthalate ...
