Abstract

The invention discloses a screen-clogging-resisting silk-screen printing screen and a preparing method thereof. The screen comprises a base body, a composite film layer is arranged on the surface of the base body and sequentially comprises an inner layer, a middle layer and an outer layer from inside to outside, the inner layer is a titanium aluminum layer, the middle layer is a titanium aluminum+ similar diamond layer, and the outer layer is a silver doped similar diamond layer. The screen has the good self-cleaning screen-clogging-resisting property, and meanwhile, the combination strengthbetween film layers is high.

Description

technical field [0001] The invention relates to the field of printing screens, in particular to an anti-blocking screen printing screen and a preparation method thereof. Background technique [0002] As a cheap coating method, the screen printing process has been widely used in various fields of the manufacturing industry, from the development of semiconductor devices, the printing of double-sided grid lines of photovoltaic cells, to the printing of ordinary planar patterns. Do not open silk screen technology. Conductive silver paste generally consists of silver powder, screen powder and organic components. Since the silver powder is easy to agglomerate, the printing paint condenses and dries on the screen during the printing process, causing the screen to be blocked. In order to overcome the blockage problem that has always plagued the process of pigment screen printing, printing paint manufacturers and users have adopted many methods, including improving the production f...
