Abstract

The invention relates to a solvent of a bismuth-oxide-base ink for glass digital inkjet printing, which is characterized by comprising the following components in percentage by mass: 65-85% of main solvent, 8-22% of dispersing agent, 6-11% of surfactant and 0.1-2% of light stabilizer, totaling 100%. The main solvent is one or mixture of any of 1-(2-methoxy-1-methylethoxy)isopropanol, 1-ethoxy-2-propanol, 1-methoxy-2-propanol and cyclohexanone. The dispersing agent is diethylene glycol butyl ether. The surfactant is 1,2-propylene-glycol diacetate. The light stabilizer is HS-508. The surface tension of the solvent is 28-32 mN / m. The solvent has the advantages of favorable dispersity for bismuth-oxide-base inorganic powder pigments, high volatilization speed and favorable inkjet printing properties. The preparation method is simple and efficient, has the advantages of favorable controllability and low cost, is suitable for industrialized large-scale production, and has wide application prospects in the field of glass digital inkjet printing.

Description

technical field [0001] The invention belongs to the technical field of glass inkjet printing, in particular to a solvent for bismuth oxide-based ink used for glass digital inkjet printing. technical background [0002] With the development and popularization of digital technology, digital inkjet printing technology has been widely used in office document printing, outdoor advertising inkjet, digital photo printing, textile inkjet printing and other fields, while the application in the glass industry has just begun. The main application is glass decoration. Glass product decoration is to make multi-color ink from powder pigment (the raw material for making pigment is powder material) and organic solvent, and print it directly onto the glass surface through a computer-controlled printer for decoration. Its advantage is that it can make full use of the rich resources of the computer, and the decoration design can be changed instantly through software signals, which improves th...
