Cleaning method of printing ink specially used for glass screen printing

Abstract

The invention belongs to the technical field of glass cleaning, and more specifically relates to a cleaning method of a printing ink specially used for glass screen printing. The cleaning method comprises following steps: a washing solution is prepared; the washing solution is introduced into a cleaning device, and is heated to 120 to 160 DEG C; glass plates to be cleaned are introduced into the washing solution, and are immersed in the washing solution, and the temperature is maintained to be constant for 2 to 3h; the glass plates are taken out from the washing solution, and are washed; the glass plates are introduced into ultrasonic equipment for ultrasonic washing, and then are dried. Compared with the prior art, the cleaning method possesses following advantages: printing ink on the glass plates can be removed completely; no damage on the printing layers on the glass plates is caused; in the washing solution, a plant based environment-friendly organic solvent and a volatile organicsolvent which are friendly to the environment are adopted, excellent oil and dirt removing effect is achieved, and no environment pollution is caused.

Description

technical field [0001] The invention relates to the technical field of glass cleaning, in particular to a cleaning method for special ink for glass screen printing. Background technique [0002] The cleaning liquid used to clean the screen printing screen is mainly cleaned by water and the cleaning liquid containing chemical properties. The ink with chemical components and the smell produced by the cleaning solution containing chemical components are not only pungent and low-toxic, but also cause pollution to the environment and cause harm to the staff who clean the screen for a long time. On the other hand, with the improvement of living standards, the printing of some high-end products requires inks with high hiding power, high insulation, acid resistance, alkali resistance, and solvent resistance. For example, at present, the inks used for glass screen printing of high-end mobile phones and tablet computers all use special inks for glass screens, but it is very difficult...

Problems solved by technology

For example, at present, the inks used for glass screen printing of high-end mobile phones and tablet computers all use special inks for glass screens, but it is very difficult to re-clean the inks for some defective products and reprint them. Conventional ink cleaners cannot achieve the purpose of cleaning. Moreover, because such high-end products are well-made, the glass printing layer is composed of organic and inorganic layers, and the single use of a certain cleaning solution will not only fail to achieve the cleaning effect, but will also damage the product.
