High near-infrared reflection blue inorganic pigment and preparation method thereof
The invention belongs to the technical field of inorganic pigments, and particularly relates to a high near-infrared reflection blue inorganic pigment and a preparation method thereof. The general formula of the blue inorganic pigment with high near infrared reflection is Zn2-xNixSiO4, wherein x is more than 0 and less than or equal to 0.5. The preparation method comprises the following steps: taking ZnO, SiO2 and NiO as raw materials, mixing according to a stoichiometric ratio, grinding for 15-30 minutes, tabletting under the pressure of 10-30 MPa, maintaining the pressure for 1-5 minutes, and finally in a box-type furnace, heating to 1300-1500 DEG C at the heating rate of 5-10 DEG C/min, sintering for 2-6 hours and cooling rate of 5-10 DEG C/min. And cooling to room temperature and grinding to obtain the blue inorganic pigment. The blue inorganic pigment synthesized by the invention is environment-friendly, non-toxic, bright in color, simple in preparation process, low in cost and short in preparation period, and has good high-temperature stability, chemical stability and high near-infrared reflectivity.
本发明属于无机颜料技术领域，具体涉及一种高近红外反射蓝色无机颜料及其制备方法。该高近红外反射蓝色无机颜料的通式为Zn2‑xNixSiO4，其中0＜x≤0.5。制备方法为：先以ZnO，SiO2，NiO为原料，按照化学计量比进行混料，研磨15‑30min，在10‑30MPa压力下压片并保压1‑5min，最后在箱式炉中，在升温速率为5‑10℃/min，升温至1300℃‑1500℃，烧结时间为2‑6h，降温速率为5‑10℃/min。冷却到室温后研磨得到蓝色无机颜料。本发明合成的蓝色无机颜料，环保无毒，色泽明亮，制备工艺简单，成本低廉，制备周期短，具有良好的高温稳定性，化学稳定性以及高近红外反射率。
