Abstract

The invention discloses a preparation method of a tin-zinc composite oxide material with an even size and a micro-nano structure, comprising the following steps of: evenly mixing tin salt and zinc salt, wherein the molar ratio of the tin salt to zinc salt is 0-1; then mixing the tin salt and the zinc salt with alkali, wherein the molar ratio of the total amount of the tin salt and the zinc salt to the alkali is 1:2-10; putting the mixture into an agate mortar or a planet agate jar and milling for 1-30 hours; carrying out filter cleaning or ultrasonic cleaning for 2-5 times after the mixture is taken out; then drying for 2-10 hours in a drying oven at the temperature of 60-100 DEG C; putting dried products in a muffle furnace for calcining 1-10 hours, wherein the calcining temperature is 300-900 DEG C; and cooling to obtain the composite oxide material. The method has the advantages of simple required process equipment, convenient operation, easy industrial production, no toxin or pollution in the procedure of the preparation process and the like, and belongs to a green synthesis method.

Description

technical field [0001] The invention relates to a preparation method of a tin-zinc composite oxide material with a uniform micronano structure. Background technique [0002] Due to the high specific surface area and quantum size effect, ultrafine nano-oxide powder materials have many excellent new properties and new uses, such as nano-zinc oxide, tin oxide, titanium oxide and other oxides used as coating additives have the ability to absorb ultraviolet rays, antibacterial and antibacterial. Mildew and other effects. With the development of science and technology, more and more inorganic oxide particles are added to polymer materials to prepare composite materials with excellent performance. For example, in the polymer industry, zinc stannate powder is usually added as a flame retardant, which has excellent flame retardant and smoke suppression effects. As a powder material for additives, composite oxides usually have more and better performance and effects than single oxid...
