Abstract
The invention relates to a low-toxicity screening washing water for screen printing, belonging to the technical field of screen printing. The low-toxicity screening washing water is prepared from the following raw materials in parts by weight: 20-40 parts of ethylene glycol monobutyl ether, 5-10 parts of ethanol, 1-8 parts of isopropanol, 3-10 parts of sodium hydroxide, 3-9 parts of polyether L61, 4-12 parts of alkylphenol polyoxyethylene, 5-15 parts of dimethyl siloxane, 5-10 parts of emulsifier, 2-9 parts of dispersing agent, 2-5 parts of surfactant and 50-75 parts of deionized water. The low-toxicity screening washing water for screen printing solves the problem of high toxicity in the screening washing water in the prior art, and thus, has better cleaning effect and lower pollution; and the screening washing water is water-based without flash point, and thus, has the advantages of high storage and use safety, low organic volatile content, high cleaning speed, no corrosivity for equipment, and no strong pungent odor.
Description
technical field [0001] The invention relates to a cleaning agent in printing production, more specifically, the invention relates to a low-toxicity screen washing water used for screen printing, which belongs to the technical field of screen printing. Background technique [0002] Screen printing belongs to stencil printing, and it is called the four major printing methods together with offset printing, embossing printing, and gravure printing. Stencil printing includes transcription, engraving, inkjet and screen printing. The principle of stencil printing is: when the printing plate (the hole that can pass the ink is made on the base of the paper film or other plate), the ink is transferred to the substrate (paper, ceramics, etc.) through the hole of the stencil through a certain pressure when printing ) to form an image or text. [0003] Screen printing originated in China and has a history of more than two thousand years. As early as the Qin and Han Dynasties in ancien...
