Abstract

The invention discloses an electronic engraving printing gravure hard copper additive which comprises a hardening agent and a gloss agent. The hardening agent is prepared from ethylene thiourea, polyethylene glycol, thiazoline-based dithio-propane sulfonate, a wetting agent, 98% sulfuric acid and purified water. The gloss agent is prepared from dithiobis-1-propanesulfonic acid disodium salt, phenyl disulfamate sodium sulfonate, acid copper leveling strong walking agent, acid copper middle-lower area walking agent, high-molecular polymer, sulfhydrazole, acid copper yellow dye, 98% sulfuric acid, 98% hydrochloric acid and purified water. The components and matching ratio are scientific and reasonable, water is added in batches, the components are sequentially added, the hardening agent and the gloss agent are prepared, the preparation process is simple, the additive is effectively used for electronic engraving printing gravure electroplating industry, and the prepared copper plating layer is large in hardness, good in smooth degree, good in flexibility and capable of being effectively stored for a long time.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to an electronic engraving and printing gravure hard copper additive. Background technique [0002] When the electronic engraving and printing gravure is engraving, the copper layer is the working surface, and because its engraving method is different from other gravures, such as Bumeilan gravure, laser engraving gravure, etc., its production methods are divided into chemical corrosion, electronic engraving and manual engraving. Electronic engraving gravure uses an electronic engraving machine to control the engraving knife to carve holes on the surface of the copper layer according to the principle of photoelectricity, while Bumeilan gravure and laser engraving gravure use chemical corrosion to form holes on the copper layer, so the quality of the electronic engraving gravure copper layer The following requirements must be met: the copper has high purity and fine grain; the surface...
