Embodiment 1

[0071] Mix tungsten hexachloride and ethanol to prepare a blue solution A with a pH value of about 0; additionally take cesium chloride (CsCl) and antimony trichloride (SbCl) 3 ) were mixed together with water in a ratio of 1 mole to 0.1 mole to prepare clear solution B. The two solutions of A and B were co-deposited to produce precipitates. The chemical reaction formula is as follows:

[0072] 2WCl 6 +C 2 h 5 OH+3H 2 O→WOCl 4 ↓+WO 2 Cl 2 ↓+6HCl+C 2 h 5 OH;

[0073] WOCl 4 ↓+WO 2 Cl 2 ↓+C 2 h 5 OH+CsCl+SbCl 3 +3H 2 O→2WO 3 ↓+Cs + +Sb +3 +Cl - +6HCl+C 2 h 5 Oh.

[0074] Next, the obtained precipitate was placed in a high-temperature furnace, and a certain flow rate of argon and hydrogen was introduced. Under the condition that the temperature increase rate of the high-temperature furnace was 2°C per minute, the high-temperature furnace was raised from room temperature to 485-485°C. 515°C (expressed as an average temperature of 500°C), and heat treatment...

Embodiment 2

[0080] With embodiment 1, but get cesium chloride and antimony trichloride (SbCl 3 ) were mixed together with water in a ratio of 1 mole to 0.5 mole to prepare clear solution B.

[0081] The transmittance of the prepared transparent heat-insulating film to a wavelength of 300-2000 nm was measured, and the results are listed in Table 1.

Embodiment 3

[0083] With embodiment 2, but use tin trichloride (SnCl 3 ) to replace antimony trichloride (SbCl 3 ) to prepare a transparent solution B.

[0084] The transmittance of the prepared transparent heat-insulating film to a wavelength of 300-2000nm was measured, and the results are listed in Table 1; the results of the life test trend chart are listed in figure 1 .

Abstract

The invention relates to a transparent thermal insulation material, which is characterized in that: the material is codoped by cross-group elements. A preparation method of the material has the characteristics of simple process and cost saving, and is specially used for preparing composite wolfram oxygen chloride powder with a chemical formula being CsxNyWO3-ZCIC, wherein Cs is cesium; N is Sn or Sb or Bi; W is wolfram; O is oxygen; and X, Y, Z and C are positive numbers and meet the following conditions that: X is less than or equal to 1.0, Y is less than or equal to 1.0, Y / X is less than or equal to 1.0, Z is less than or equal to 0.6, and C is less than or equal to 0.1. A transparent thermal insulation film prepared by the composite wolfram oxygen chloride powder has the characteristics of high transparency and high thermal insulation, is applied to paste on glasses of buildings and automobiles so as to separate infrared wave bands with wavelength of 800-2000nm, contributes to realizing effects of thermal insulation and energy conservation, and also can be used for a combined type base plate of an electronic component.

Description

technical field [0001] The invention relates to a transparent heat-insulating material and its preparation method, in particular to a transparent heat-insulating film made of the transparent heat-insulating material, which has both high transparency and excellent infrared barrier properties. Background technique [0002] In order to achieve the purpose of energy saving and carbon reduction, in the prior art, a layer of heat insulating material is usually pasted on the glass of buildings and automobiles to achieve the effect of heat insulation and energy saving. The physical properties of metal oxides have good heat insulation effects, and have been widely used as materials for blocking infrared rays. [0003] For example, US Patent No. 5,385,751 discloses a fluorine-doped tungsten oxide infrared-blocking material, but the manufacturing method uses chemical vapor deposition (Chemical Vapor Deposition), which has the disadvantages of expensive manufacturing equipment and high ...
