Abstract

The invention discloses an inorganic fusion cake for tempered glass inkjet printing ink. The inorganic fusion cake contains the following components in percentage by weight (100% in total): 25%-45% of SiO2, 15%-30% of ZnO, 10%-30% of Bi2O3, 5%-20% of B2O3, 1%-10% of K2O, 1%-10% of Na2O, 1%-10% of TiO2, 1%-10% of Li2O and 0.1%-10% of V2O5. The automotive tempered glass inkjet printing ink prepared from the inorganic fusion cake has high acid resistance and sun-shading capacity and can meet relevant national requirements on the acid resistance and sun-shading capacity of an automotive glass coating layer, the melting point of the inorganic fusion cake can be maintained in a tempered sintering temperature of 650-750 DEG C, and the tempered sintering step in the later period of the automotive tempered glass inkjet printing ink can be smoothly carried out. The invention further provides the automotive tempered glass inkjet printing ink prepared from the inorganic fusion cake, which can meet relevant national requirements on the acid resistance and sun-shading capacity of the automotive glass coating layer.

Description

technical field [0001] The invention relates to the field of automobile tempered glass printing, in particular to an inorganic frit of glass inkjet printing ink and the automobile tempered glass inkjet printing ink prepared by using the inorganic frit. Background technique [0002] At present, my country's automotive tempered glass production has formed a huge industry. In order to achieve the purpose of blocking the sun, the common processing method is to screen-print dark glass ink on the tempered glass of the car. However, the operation of screen printing is generally more complicated and requires a lot of manpower input, and the waste generated by printing also causes a certain degree of pollution to the environment. [0003] In recent years, the technology of using inkjet printing to print the digital pattern in the computer non-contactly on the glass surface through the nozzle has appeared abroad. This technology uses special printing equipment to print glass printin...
