喷打用蓝色陶瓷表面装饰墨水的制备与性能

PHYSICOCHEMICAL PROPERTIES AND PREPARATION OF BLUE SURFACE DECORATE CERAMIC INK FOR CONTINUOUS INK

制备了一种与传统陶瓷表面装饰的新技术(连续式喷墨打印法)配套的新型墨水——蓝色陶瓷表面装饰墨水。它以陶瓷颜料为基本着色料,用溶胶—凝胶法制备,以连续式喷墨打印墨水的质量标准为参照标准。经测试,所制墨水的电导率、表面张力、粘度等理化性能完全符合喷墨打印墨水的要求,适用喷墨打印法陶瓷装饰工艺的需要。研究了分散剂、粘接剂、pH值、固含量等工艺因素对该墨水性能的影响。该墨水制成时为草绿色,经煅烧,各组分反应生成颜料,显现蓝色。

Preparation and physicochemical propreties of blue surface decorate ceramic ink for jet-print forming has been investigated in this paper. This blue ink containing ceramic decorative components of pigments, prepared by sol-gel method (it has not been widely used in conventional ceramics decoration ,such as glazed tile and dinner set ). Its quality standard according as the quality standard of Continuous Ink- Jet Printing. Testing result showed that ours ink conform to standards of its physicochemical properties, such as conductance, surface tension, viscosity and so on . And then study the influence of its technological process factor, such as scattering reagent, thickening, pH number and solid volume fraction. When the ceramics decorative ink printed on ceramic, colour is grass green, But the colour is different after fired, Because components be reacted pigments, the colour of Nickle Alumina blue ink is blue.
