Embodiment 1

[0028] 156.36g SnCl 4 and 36.52 g SbCl 3 Dissolve in 650mL of absolute ethanol solution to obtain a colorless and transparent tin-antimony mixed solution. Mix 80.00g of ammonium bicarbonate and 800.0g of absolute ethanol solution for beating, then dissolve 1.15g of ammonium acetate in a small amount of ethanol and add it to disperse. A solid-liquid suspension mixed solution was obtained. Under the condition of stirring, the tin-antimony solution was mixed with the solid-liquid suspension solution and reacted. The reaction temperature was 5°C, the pH value was 5, and the reaction time was 2.0h to obtain white milky Sn(OH) 4 and NH 4 A Cl mixture precipitated. After filtration, vacuum-dry at 40°C, after recovering ethanol, add 670.0g deionized water to the filter cake to dissolve and disperse, filter, wash with deionized water until the presence of chloride ions cannot be detected, then dehydrate with absolute ethanol, and Vacuum drying at 90°C to obtain white powder Sn(OH) ...

Abstract

The invention discloses a preparation method of a tin antimony oxide organic nano paste, which comprises the following steps: mixing ATO nano powder with an organic solvent, adding tetraethoxysilane for carrying out a heat preservation reaction, cooling, adding the organic solvent again and polyethylene imine, adjusting the pH value of the obtained mixture, and grinding the obtained product so as to obtain an ATO organic nano paste. The method disclosed by the invention is simple in process, low in energy consumption and low in cost; and due to the adoption of an efficient composite dispersant and a unique dispersion technology, a stable ATO organic nano paste can be prepared in a relatively short time.

Description

technical field [0001] The invention belongs to the field of tin antimony oxide nano powders, in particular to a preparation method of tin antimony oxide organic nano slurry. Background technique [0002] Energy saving and environmental protection have become the theme of today's era. Building thermal insulation coatings, thermal insulation glass and automotive thermal insulation films are some important ways to save energy in daily life. In order to eliminate the electrostatic hazards and radiation hazards caused by electronic equipment such as computers and televisions, it is necessary to coat the surface of the electronic equipment with antistatic and radiation-proof materials. Nano antimony tin oxide (ATO) is the additive that endows these materials with the above functions. ATO is an n-type semiconductor material with good electrical conductivity and excellent optical properties. Its transmittance in the visible light region can reach 85%, its absorption rate in the i...
