Embodiment 1

[0029] At a temperature of 85°C, mix and stir 4% aluminum isopropoxide and deionized water for 1 hour for hydrolysis, add nitric acid at intervals to form a white transparent alumina sol-gel, and prepare the nano-aluminum powder according to the mass ratio 1% was gradually added to the alumina sol-gel for blending, and then the blended sol-gel was stirred for 1.5 hours with a stirrer with a rotating speed of 10,000 rpm, so that the blended sol-gel was uniformly dispersed, and the mass ratio was mixed during the stirring and dispersing process Add 0.02% EFKA-4300 dispersant to the blended sol-gel in three batches, and then add 1% polyacryl butyral to the above sol-gel in two batches within 1.5 hours, and continue stirring After 1.5 hours, a sol-gel type nano-aluminum powder ink for inkjet printers with excellent performance was obtained.

[0030] The ink of this embodiment was tested according to the national standards QB / T2730.1-2005, QB / T2603-2007, GB / T13217.2-2009, GB / T18724...

Embodiment 2

[0032] At a temperature of 90°C, mix and stir 6% aluminum isopropoxide and deionized water for 1 hour for hydrolysis, add nitric acid at intervals to form a white transparent alumina sol-gel, and prepare the nano-aluminum powder according to the mass ratio 3% was gradually added to the alumina sol-gel for blending, and then the blended sol-gel was stirred for 2 hours with a stirrer with a rotating speed of 50,000 rpm, so that the blended sol-gel was evenly dispersed. During the stirring and dispersing process, the mass ratio Add 0.05% EFKA-4300 dispersant to the blended sol-gel in three batches, and then add 3% polyacryl butyral to the above sol-gel in two batches within 2 hours, and continue stirring After 2 hours, a sol-gel type nano-aluminum powder ink for inkjet printers with excellent performance was obtained.

Abstract

The invention discloses a processing method of nano-aluminum powder ink for a sol-gel type inkjet printer. Mix and stir aluminum isopropoxide and deionized water for 1 hour to hydrolyze, add nitric acid at intervals to form a white transparent alumina sol for later use; gradually add nano-aluminum powder to the above sol-gel according to a certain mass ratio and mix it with a stirring device Disperse the above blended sol-gel evenly, add the dispersant in batches during the dispersion process, add polypropylene butyral to the above sol-gel in batches, and then continue to stir the above sol-gel solution, that is A sol-gel type nano-aluminum powder ink for an ink-jet printer with excellent performance is obtained. The method of the present invention is applied to the production of thin-film solar cells with simple production process and low manufacturing cost; the produced thin-film solar cells are natural, low-pollution, lower in price, suitable for portable electronic products, and are highly competitive energy substitutes in the future The program has potential extremely broad practicability and market promotion prospects.

Description

technical field [0001] This patent relates to a processing method of nano-aluminum powder ink for sol-gel inkjet printers, especially a processing method of nano-aluminum powder ink applied to thin-film solar cells. Background technique [0002] With the rapid development of human civilization, the demand and dependence on energy are also increasing day by day. Due to the massive exploitation of traditional petrochemical energy such as oil, natural gas and coal, not only will it soon face the crisis of depletion, but the price has also fluctuated sharply recently. . In addition, after burning fossil fuels, carbon dioxide and other wastes will be produced, which will cause environmental pollution such as greenhouse effect and acid rain. Therefore, the world is paying more and more attention to renewable energy, such as the use of wind, water and solar energy, which are natural and low-pollution Sexual energy is a very competitive energy alternative in the future. [0003] S...
