High-flash-point screen printing ink cleaning agent

Abstract

The invention discloses a high-flash-point screen printing ink cleaning agent, which consists of the following ingredients in percentage by volume: 15 to 60 percent of dipropylene glycol, 20 to 75 percent of C6-C9 ester and 10 to 25 percent of oleic acid. The high-flash-point screen printing ink cleaning agent can be used at normal temperature, the efficiency is high, the energy is saved, the flash point is high, the safety performance is high, the cleaning is thorough, the pollution is small, the toxicity is low, the harm to the human body is small, in addition, the preparation is easy, and no damage is caused on printing screens.

Description

technical field [0001] The invention relates to a solvent-based cleaning agent suitable for the screen printing industry, especially suitable for further deep cleaning of the screen after being washed with ordinary screen washing water, so as to thoroughly remove residual ink. Background technique [0002] Screen printing is to stretch silk fabrics, synthetic fabrics or wire mesh on the screen frame, and adopts the method for manual engraving paint film or photochemical plate-making to make screen printing forme. Modern screen printing technology is to use photosensitive materials to make screen printing plates by means of photographic plate making (so that the screen holes of the graphic part on the screen printing plate are through holes, and the screen holes of the non-graphic part are blocked. live). During printing, through the extrusion of the scraper, the ink is transferred to the substrate through the mesh of the graphic part, forming the same graphic as the origina...
