Abstract

The invention provides a preparation method of nano tin antimony oxide powder and solves the technical problem that a preparation method in the prior art has complex steps, requires manual operations and is low in production speed. The preparation method includes the following steps: A) dissolving tin tetrachloride and antimony nitrate in dilute hydrochloric acid, stirring the solution and gradually adding an alkali solution until the pH value is 7-9, continuously stirring the solution until tin ions and antimony ions are completely precipitated to prepare a tin hydroxide and antimony hydroxide precursor; B) filtering and separating the tin hydroxide and antimony hydroxide precursor and washing the tin hydroxide and antimony hydroxide precursor with deionized water; C) adding water and polyethylene glycol to the washed precursor, stirring the mixture uniformly, moving the mixture to a reaction kettle to prepare nano slurry; and D) separating and drying the nano slurry, and calcining the nano slurry at 400-700 DEG C for 2-6 h, and crushing the calcined substance through an air-flow crusher to prepare the nano tin antimony oxide powder. The method is high in production efficiency.

Description

technical field [0001] The invention relates to a preparation method, in particular to a preparation method of nano tin antimony oxide powder. Background technique [0002] Nano-tin antimony oxide is a new multifunctional transparent material with high performance and high added value in the non-ferrous metal industry chain, because of its good electrical conductivity, light color transparency, blocking infrared and ultraviolet rays, good weather resistance and stability and Catalytic, etc., widely used in transparent thermal insulation coating film, antistatic coating and antifouling self-cleaning coating film and other fields. [0003] After searching, for example, Chinese patent literature discloses a low-temperature ball milling preparation method of tin antimony oxide nanopowder [application number: 201210582264.3; publication number: CN 103041896A]. The preparation method of the antimony tin oxide nanopowder is characterized in that it is a low-temperature ball millin...
