Abstract

A method of manufacturing a composite tungsten oxide nanoparticles, and infrared-shielding infrared absorbing material body, the use of the infrared-absorbing material comprises a composite tungsten oxide nanoparticles are manufactured by sol-gel method, the manufacturing method for the first reaction in the sol-gel process the proportion of the desired composite element directly added to the solution and allowed rapid precipitation, drying and then heat-treated after special atmosphere to obtain a composite tungsten oxide nanoparticle material, or the general formula M1xM2yWO M1xM2yWORz or M1xWORySz, wherein M1 is IA - Group IIIA or a transition metal element, M2 of Group IA - IIIA or a transition metal elements, W is tungsten, O is oxygen, R, S of IVA - VIIA elements, specifically, R, S may be in sol-gel when you import or atmosphere heat treatment during synthesis. This material is used in the field of infrared-absorbing material, and thus the production method can improve the tungsten oxide nanoparticles molecular absorption wavelength greater than 1200nm infrared.

Description

technical field

[0001] The invention relates to an infrared absorbing material particle and a manufacturing method thereof, and in particular to a manufacturing method of a composite tungsten oxide nano particle, an infrared absorbing material and an infrared shielding body. Background technique

[0002] By the way, in addition to visible rays, the sunlight incident from the windows or doors of various buildings and vehicles also includes ultraviolet rays and infrared rays. Among them, near-infrared rays with a wavelength between 800 and 2500 are also called heat rays, which cause the indoor temperature to rise. the main reason.

[0003] In order to prevent this from happening, in recent years, a shield that can sufficiently absorb visible light and block infrared rays has been actively developed in order to suppress the rise in indoor temperature while maintaining brightness. For example, early infrared blocking glass was mainly coated with metal oxides or metals such as s...
