【摘要】 用易于工业化生产的乳状液法一步合成出含立方ZnS(直径在15～30nm)和正交BaSO4(直径在60～100nm)的近球形纳米立德粉复合颜料.与市售/自制体相立德粉相比,纳米立德粉的着色力提高了20%/25%,吸油量提高了75%/85%,透明性能明显改善.更多还原

【Abstract】 NanoZnSBaSO4 (nanolithopone) was prepared by W/O emulsion. The sizes, morphology and structures of the products were determined by TEM and XRD. Its main properties were compared with those of purchased/ selfpreparation bulk lithopone. The results show that the composite nanoparticles are approximately spherical with diameters of 15～30 nm for cubic ZnS and 60～100 nm for orthorhombic BaSO4. The coloring capacity and the oil absorption of the nanolithopone increases 20%/25% and 75%/85% respectively, and the transparence improves obviously.更多还原
