Embodiment 1

[0062] A method for preparing paper luminescence based on an all-printing process, specifically implemented according to the following steps:

[0063] Surface modification of paper:

[0064] (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 90°C for 1 hour, the surface of the paper surface will be flat, forming a filling layer on the surface.

[0065] (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 9g / m 2 , After the coating is completed, dry in an oven at 90°C for 1 hour, the surfac...

Abstract

The invention discloses a paper luminous structure and a preparation method based on a full printing process, which relate to the materials used for each functional layer of paper luminescence, the printing method and the paper treatment method. The printing methods used include screen printing and inkjet printing. The treatment of paper includes: filling layer, improving layer, barrier layer, paper surface coating, printing varnish layer, which are used to adjust the surface roughness and porosity of the paper. The paper luminous structure functional layer provided by the invention has the following layers from bottom to top: paper base, filling layer, improvement layer, barrier layer, paper surface coating, printing varnish layer, conductive anode layer, hole transport layer, Light emitting layer, electron injection layer, conductive cathode layer. The invention is used to realize the patterning of light on packaging paper, and provides technical support for the future application of this technology to light or lighting on printed intelligent packaging products.

Description

technical field [0001] The invention relates to the fields of paper, printing and paper-based materials, and relates to a method for preparing 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-luminescent organic light-emitting devices have unique advantages such as planar self-luminescence, fast response, wide viewing angle, thin and light volume, and can be fabricated into bendable, rollable and even foldable devices. They are known as the most promising next-generation light-emitting and display technologies. At present, some electroluminescent organic light-emitting devices have been successfully applied in mobile phones, tablet computers, TVs, wearable devices, etc. In the preparation of existing organic light-emitting devices, in the selection of substrates, basically all are based on glass substrates, or polyethylene terephthal...
