Problems solved by technology

However, these inks have great disadvantages: the temperature required for high-temperature sintering inks is usually above 600°C, which consumes a lot of energy; self-drying solvent-based inks have a large amount of VOC emissions when drying, polluting the environment, and the drying time is relatively long , You need a lot of space to put these wet prints, even after the surface is dry, the ink is easy to be wiped off, and it takes a week to dry completely; two-component heat-curing glass ink needs to be cured at 160°C for 30 minutes , the energy consumption is also very large, and the space occupied is also large; water-based glass ink is relatively environmentally friendly, but the curing temperature is about 160 ° C, and the curing time is about 30 minutes, or even longer

Abstract

The invention discloses thermosetting type glass screen printing ink. The thermosetting type glass screen printing ink includes, by weight, 40%-65% of Evonik EP112 saturated polyester, 21%-45% of titanium dioxide TR-92, 0.5%-2.0% of fumed silica A-200, 10%-15% of methylated amino resin MF915, 1.0%-4.0% of adhesion promoters LTW, 0.5%-1.5% of antifoaming agents FOAMEXN, 0-1.0% of flatting agents BYK-310, 0-1.0% of brightening agents OB and 2%-6% of DBE solutions. A preparation method of the thermosetting type glass screen printing ink includes the steps that the saturated polyester, the titanium dioxide and the fumed silica are firstly stirred evenly, then the methylated amino resin, the adhesion promoters, the antifoaming agents, and / or the flatting agents, and / or the brightening agents are added into the mixture, and the DBE solutions are added finally. The thermosetting type glass screen printing ink has good adhesion, water resistance, acid and alkali resistance, cold and hot impact resistance, butanone dissolution resistance, fast yellowing resistance, high temperature yellowing resistance, flexibility, constructability and ultraviolet resistance.

Description

technical field [0001] The invention belongs to the field of glass printing inks, and in particular relates to a thermosetting glass printing ink and a preparation method thereof. Background technique [0002] Screen printing is an ancient printing method. Like movable type printing, it is an invention in ancient my country. It originated from the clip printing process in the Qin and Han Dynasties and has a history of more than 2,000 years. Although my country's screen printing originated very early, the development of modern screen printing technology is slow. Compared with foreign advanced screen printing countries, there is still a certain difference in the technical level of our country, and the developed inks are somewhat discolored when used. Phenomenon, can not fully meet the requirements. [0003] With the increase in the production and application of glass screen printing ink products, the pollution caused by organic solvents (VOC) in the ink, the poison to the huma...
