摘要
矿物-TiO_2复合乳浊剂是无机矿物基体与TiO_2通过微纳米颗粒有序复合技术制备的粉体材料。本文介绍了矿物-TiO_2复合乳浊剂的理化性质和微观结构,对CaCO_3为基体的复合TiO_2乳浊剂制备卫生洁具进行了试验研究。结果表明,矿物-TiO_2复合乳浊剂主要由矿物颗粒表面均匀、牢固包覆TiO_2复合颗粒所组成,矿物与TiO_2颗粒通过各自表面的一OH形成氢键或脱羟基反应进行连接;将矿物-TiO2复合乳浊剂在陶瓷釉料中添加可烧制成无放射性危害的白色釉面卫生洁具,其釉面乳浊效果、色度和光泽等性能与添加同比例ZrSiO_3釉面相当,釉层物质达到国标《室内装饰装修材料-建筑材料放射性核素限量》(GB6566-2010)A类指标要求。含矿物-TiO_2复合乳浊剂釉层的乳浊相为榍石,复合乳浊剂中矿物-TiO_2界面处-Ca-O-Ti-键对釉料高温烧成榍石起诱导作用,并由此抑制TiO_2生成金红石相及导致的黄变现象。
Mineral-TiO_2.composite opacifier is a powder material prepared by the orderly composite between inorganic minerals substrate and TiO_2 particles.In this paper,the physical and chemical properties,microstructure of mineral-TiO_2 composite opacifiers were introduced,and the preparation of sanitary utensil using CaC03 substrate-TiO_2 composite opacifier was studied.The results show that the mineral-TiO_2 composite opacifiers are mainly composed of the composite particles characterized as the mineral particles surface coated by TiO_2 particles firmly and uniformly,and the minerals particles and TiO_2particles combined by forming hydrogen bonds or dehydroxylation reacting through the-OH groups on their surface;A ceramic sanitary utensil with the white glaze and Without radioactivity was prepared by using mineral- TiO_2 composite opacifier.Its opacification,chromaticity,glossiness-and other properties are similar to those of the glaze added ZrSiO_3 with same ratio.The glaze layer composition has reached the A class requirements of the state standard named 《Radioactivity nuclide limit quantity of indoor decoration materials-building materials 》(GB6566-2010).The opacification phase of the glaze layer containing mineral- TiO_2 composite opacifier is sphene,and the-Ca-O-Ti bonds at the interfaces of mineral- TiO_2particles induce the formation of sphene during the high temperature calcination process,thus the formation of rutile from TiO_2 can be inhibited,and then the yellowing phenomenon can be avoided.
