Problems solved by technology

These production methods have complicated processes, heavy environmental pollution, or long production cycles, low product yields, and large particle sizes, while the preparation methods of nano-scale antimony oxide are less and the processes are more complicated, low efficiency, dependence on resources, and environmental protection. The impact of the environment is also more serious

Abstract

A preparation method of nanometer antimony oxide comprises the following steps of: (1) using industrial antimony powder of 100-500 meshes as a raw material, using hydrogen peroxide as an oxidizing agent, and using deionized water or alkylphenol polyoxyethylene or polyoxyethylene sorbitan monooleate or anhydrous ethanol as a liquid additive which can be individually used or used for complex formulation at any proportion; (2) mixing the oxidizing agent and the liquid additive, mixing the mixture with the antimony powder in a bowl mill according to the volume ratio of the mixture to the antimony powder being 0.2ml / g-5ml / g, wherein the ball milling time is 10-60 hours; and (3) filtering, drying and extracting the ball milling powder after ball milling to obtain nanometer antimony oxide.

Description

technical field [0001] The invention relates to the preparation of nanometer antimony oxide. Background technique [0002] Antimony oxides are widely used. Antimony trioxide is a flame retardant synergist. It is used as a filler in the rubber industry with antimony sulfide, as a precipitant in the production of titanium dioxide, and a small amount of antimony trioxide is added to gasoline. Antimony can make it burn completely and reduce air pollution. In the organic synthesis industry, it is used as a catalyst for the oxidation polymerization of propylene and ammonia to produce artificial wool; antimony tetroxide and antimony pentachloride can be used as flame retardant Auxiliary, glass clarifying agent and covering agent; antimony pentoxide can also be used in the petroleum industry as a protective agent for catalysts to prolong the service life of catalysts. [0003] The ball milling method is a powder preparation method that uses the rotation or vibration of the ball mil...
