| titleOfInvention | A kind of method that the chromic oxide-based pigment of near-infrared high reflection is prepared by hydrated chromium oxide |
| abstract | The present invention relates to a kind of method that the chromic oxide-based pigment of near-infrared high reflection is prepared by hydrated chromium oxide.It is using hydrated chromium oxide as raw material, after being well mixed with a certain proportion of additive, more than 0.5h is calcined at 950~1300 DEG C, obtains chromic oxide-based pigment.The hydrated chromium oxide can be by solid phase method（Such as the method for chromic salts gas reduction）Prepare, also can be by liquid phase method（Precipitation, hydro-thermal etc.）Prepare.The additive be containing radius 0.040~0.080nm such as aluminium, titanium, vanadium, manganese, iron, cobalt plasma compound in one or more.The near infrared reflectivity of gained chrome oxide green pigment of the invention is more than 85%, it is seen that light region is dirty-green, and colorimetric parameter is respectively：Brightness L* is 40~45, and red value of green a* is 16~18, and b* is 15~22 for champac value.Compared with prior art, the method provided by the invention that the chromic oxide-based pigment of near-infrared high reflection is prepared by hydrated chromium oxide is a kind of cleaning preparation technology, and products obtained therefrom has high near infrared reflectivity while chromium oxide pigments green hue is kept. |
