FIELD: chemistry.
SUBSTANCE: invention relates to a particle dispersion shielding thermal radiation, a method for its production and a method for obtaining coating material for the purpose of shielding thermal radiation. The particle dispersion shielding thermal radiation contains indium-tin oxide (hereinafter – ITO) particles having the capability of shielding thermal radiation, a solvent containing 60% by wt. or more of water, and a dispersing agent. ITO particles have a specific surface area according to the BET method of 20 m2/g or more, have blue or dark blue tone represented by a value L of 50 or less, a<0 and b<0 in the Lab color model, and they are represented in the amount of 3-60% by wt. relatively to 100% by wt. of the dispersion. The solvent is a component obtained by removing the heating residue from the particle dispersion shielding thermal radiation, and is presented in the amount of 28.0-96.7% by wt. relatively to 100% by wt. of the dispersion. The dispersing agent is one type or two or more types of dispersing agents selected from a group including a phosphate ester-based dispersing agent, a polyglycerin-based dispersing agent, a polyvinylpyrrolidone-based dispersing agent and a polyacrylate-based dispersing agent. The content of the active ingredient(s) of the dispersing agent is 0.05–80 wt. parts relatively to 100 wt. parts of ITO particles.
EFFECT: development of a particle dispersion shielding thermal radiation, which is excellent from the point of view of the effect of cutting off thermal radiation and which has a high coefficient of visible light transmittance and high transparency, as well as development of a method for producing a particle dispersion shielding thermal radiation in a simple and easy way.
