Embodiment Construction

[0025] see figure 1 Shown, preparation method of the present invention, as following steps:

[0026] A. Preparation of Indium Tin Oxide

[0027] The ITO target is mainly made of indium oxide (In 2 o 3 ) and tin oxide (SnO 2 ) composed of nanometer metal oxides, has good electrical conductivity, transparency, heat insulation, UV protection and other properties, and In can be adjusted according to different uses 2 o 3 and SnO 2 The proportion of ITO targets with different characteristics can be obtained. Regular products are In 2 o 3 :SnO 2 =9:1. In the oxide conductive film, the In doped with Sn 2 o 3 (ITO) film has the highest light transmittance and good electrical conductivity, and it is easy to etch fine patterns in acid solution, of which the light transmittance is over 90%. In ITO, its light transmittance and resistance can be determined by In 2 o 3 with SnO 2 ratio to control.

[0028] The steps of the method adopted in this embodiment are as follows:

Abstract

The invention discloses a preparation method of an ITO coating film target material, and relates to the technical field of coating film. The method comprises the steps of preparing an indium tin oxide, mixing oxide formula, adding an adhesive, sintering, etc. The method is scientific and reasonable in technology design; the density of the target material is proper, and the uniformity of the targetmaterial is high; the preparation is convenient; the production efficiency is high; the cost is saved; the action is safe and reliable; the method is applicable to coating film of a lens, and cracking is avoided; the performance is stable; the adhesion performance is high; a formed coating film is high in uniformity, conductivity and transparence; electronic radiation, UV and blue rays which areharmful to human bodies can be effectively cut off, and thus the product quality is ensured.

Description

technical field [0001] The invention relates to the field of coating technology, in particular to an ITO coating target material and a preparation method thereof. technical background [0002] Optical coatings are often used on lenses such as myopia, hyperopia, and reading glasses. The metal thin film of the existing optical coating technology has a certain degree of light transmission, but has a large absorption of light, low hardness and poor stability. With the development of society and the rapid advancement of science and technology, people's demand for functional materials is increasingly urgent, and they are actively seeking a high-quality coating material with better transparency and conductivity, which can cut off harmful electronic radiation, ultraviolet rays and blue light, and Can minimize production costs. In recent years, although there have been many reports on the preparation methods of ITO (Indium Tin Oxides) coating targets—indium tin oxide nanopowders, t...
