Embodiment 1

[0017] Weigh 0.1026g (0.45mmol) of antimony trichloride and dissolve it in 15ml of absolute ethanol to obtain a colorless and transparent solution. While stirring, add 30ml of deionized water dropwise to the ethanol solution of antimony trichloride, continue to stir for 0.5 hours after the dropwise addition, and transfer the obtained milky white mixed solution to a stainless steel water liner lined with polytetrafluoroethylene. In a thermal reaction kettle, put it in an oven, and react at 180°C for 2 hours. After the reaction, the white precipitate obtained is washed with alcohol and deionized water for several times, and dried at 80°C to obtain antimony-based oxides (including antimony oxychloride Sb 8 o 11 Cl 2 and antimony trioxide Sb 2 o 3 ) Nanoflower clusters composed of nanorod bundles. Its SEM photos and TEM photos are attached figure 1 , 2 As shown, it can be found that the structure of the prepared antimony oxychloride is a nano-flower cluster microsphere comp...

[0019] Weigh 0.1026g (0.45mmol) of antimony trichloride and dissolve it in 15ml of absolute ethanol to obtain a colorless and transparent solution. While stirring, add 30ml of deionized water dropwise to the ethanol solution of antimony trichloride, continue to stir for 0.5 hours after the dropwise addition, and transfer the obtained milky white mixed solution to a stainless steel water liner lined with polytetrafluoroethylene. In a thermal reaction kettle, put it in an oven, and react at 180°C for 20 hours. After the reaction, the white precipitate obtained is washed with alcohol and deionized water for several times, and dried at 80°C to obtain antimony-based oxides (including antimony oxychloride Sb 8 o 11 Cl 2 and antimony trioxide Sb 2 o 3 ) nanowires. Its SEM photos and TEM photos are attached image 3 , 4 As shown, it can be seen that when the reaction time is prolonged, the nanoflower cluster structure composed of the original nanorod bundles continues to self-a...

Abstract

The invention discloses a hydro-thermal synthesis method for antimony-based oxides (comprising antimonic oxychloride Sb8O11C12 and diantimony trioxide Sb2O3), which comprises the following steps: a solution of the trichloride antimony, ethanol and water is subjected to hydro-thermal reaction in a hydro-thermal reaction kettle taking polyfluortetraethylene as an inner lining at a temperature of between 160 and 200 DEG C for 2 to 20 hours, and then the precipitate is washed and dried to obtain antimony-based oxides with nanometer cluster or long nano-wire structures consisting of nano-rods. During the preparation, no any other surfactant is used, ordered structures of the antimony-based oxides are all formed by small and short nano-rods through self-assembly, and the flame-retardant properties of the antimony-based oxides can be greatly improved through theoretical analysis due to the ordered orientation arrangement structures of the antimony-based oxides.

Description

technical field [0001] The present invention relates to template-free hydrothermal method, exactly a kind of antimony-based oxide (including antimony oxychloride Sb 8 o 11 Cl 2 and antimony trioxide Sb 2 o 3 ) hydrothermal synthesis method, the form of the antimony-based oxide product is nano-flower clusters and long nano-wires composed of nano-rods, and no surfactant is added during the preparation process, which belongs to the technical field of nano-material research for the preparation of new structures. Background technique [0002] The antimony-halogen flame retardant synergistic system has become one of the most important flame retardants due to its excellent price / efficiency ratio. As an important inorganic flame retardant, antimony trioxide must be used in combination with halogen flame retardants to achieve Antimony oxychloride is a compound containing both antimony and halogen. It has a certain flame retardant effect, and it can be used in conjunction with hal...
