preparation example Construction

[0016] A method for preparing millimeter-sized zirconia particles for application in the field of chemical protection, comprising the following steps:

[0017] 1. Synthesis of high specific surface nano zirconia

[0018] Zirconium oxychloride is used as zirconium source, fatty acid methyl ester ethoxylate is used as template agent, and ammonium bicarbonate is used as precipitating agent; 0.2-0.6mol / L ammonium bicarbonate solution is slowly dropped into 20-30mL fatty acid at room temperature In the methyl ester ethoxylate solution, fully stir for 20 minutes, then add this mixed solution into 0.2-0.4mol / L zirconium oxychloride solution while stirring, and stir with magnetic force for 30 minutes; hydrothermal synthesis reaction at 140°C for 10-12 hours ; After cooling, the solid precipitate is placed on a surface dish and dried at room temperature for 24-48 hours, and then placed in a muffle furnace for high-temperature calcination at a calcination temperature of 300-380°C;

Abstract

The invention discloses a millimeter-level zirconium oxide particle preparation method for application in the chemical protection field. The millimeter-level zirconium oxide particle preparation method for the application in the chemical protection field comprises the following steps: using zirconium oxide powder as a raw material, and screening the zirconium oxide powder by a 0.08 mm standard screen to remove impurities and big conglomeration particles; using the 0.08 mm standard screen to screen a solid adhesive, and keeping particle sizes of powder particles to be consistent; weighing the zirconium oxide powder and the adhesive according to a mass ratio of 2:1; uniformly mixing the zirconium oxide powder and the adhesive; weighing a fixed amount of tap water, wherein the usage amount ofthe tap water is 50-60% of a mixed material; adding the tap water to the mixed material during stirring; pressing the mixed material into cakes by means of outside force; after naturally drying the cakes for 24 hours, placing the naturally dried cakes in a drying box to be activated and calcined at 140 DEG C; and after cooling the activated and calcined cakes, crushing and screening the cooled cakes into particles with particle sizes of 0.6-1.6 mm. The millimeter-level zirconium oxide particle preparation method for the application in the chemical protection field, disclosed by the invention,has the advantages that the forming degree is good, the technological condition is simple, the most important thing is that the strength of the prepared millimeter-level particulate matter is high, and influences on porosity and physical and chemical properties of a body material are relatively small.

Description

technical field [0001] The invention belongs to the field of preparation of protective materials, in particular to a method for preparing millimeter-sized zirconia particles for application in the field of chemical protection. Background technique [0002] In order to deal with the dual threats of classical chemical agents and toxic industrial chemicals (TICs), scholars at home and abroad have actively carried out research on various types of protective materials, among which porous metal oxide materials represented by nano-zirconia have high specific surface area, high Reactivity has received much attention and has become the focus of research. [0003] However, no matter what approach and technical route is adopted, the prepared nano-zirconia is a powder material. In the field of chemical protection, it is necessary to comprehensively consider various factors such as protective function, breathing air resistance, air volume, and wearing comfort. In addition to the protect...
