摘　　要：以Stober法合成的二氧化硅微球为模板,采用化学水浴沉淀法制备SiO2@CdS壳层微球色料,再通过碱液腐蚀得到空心CdS微球色料.利用XRD、SEM和全自动色度仪等测试手段表征了CdS色料的物相组成、微观形貌和呈色性能.通过色料在水和乙醇溶液中的分散后沉淀研究色料的悬浮性.结果表明:合成的CdS色料是由六方晶型的CdS小颗粒自组装而成的球形颗粒,呈现鲜艳的黄色色调.与商业CdS对比发现,SiO2@CdS核壳色料和空心CdS色料的悬浮性均有显著提高,且空心CdS色料表现出更佳的悬浮性,为CdS色料在涂料或油漆中均匀悬浮提供了保证.In the paper,Si02·CdS microspheres pigments were synthesized by chemical pre-cipitation water bath reaction, using silica microspheres prepared by the stober method as templates. Then,CdS hollow microspheres pigments were prepared through etching Si02 @ CdS microspheres pigments in alkaline solution. The phase composition, micromorphology and color performance of the synthesized CdS pigments were characterized by XRD,SEM and automatic color analyzer. The suspension performance was researched through dispersion and precipitation of the CdS pigments in water and ethanol mixed solution. The results show that the synthesized CdS pigments are composed by lots of CdS miniparticles with hexagonal structure, owning microspheres morphology and bright yellow color. Comparing with the commercial CdS pigments,the suspension performance of the Si02@CdS microspheres pig-ments and CdS hollow microspheres pigments significantly reveal significant improvement. Moreover,the CdS hollow microspheres pigments shows a better suspension performance,which will provide a fundamental guarantee for CdS pigments uniformly suspending in coat-ing or painting.
