Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the copper powder produced by the laser engraving equipment (ie direct engraving machine) in the existing plate-making process melts and solidifies at high temperature and adheres to the engraving head, causing scratches on the copper surface. scratches, even pattern scratches, and oxidation and discoloration of the copper surface under high temperature, etc., provide a protective agent for laser plate direct engraving that can protect the copper surface and patterns from scratches, random flowers, and prevent copper surface oxidation and discoloration and its preparation method

Abstract

The invention discloses a protective agent for laser plate direct engraving and a preparation method thereof. The components of the protective agent are, by mass, 1.6-2% for vegetable oil and 0.25-0.5% for castor oil polyoxyethylene ether emulsifier %, 0.02‑0.10% for fatty alcohol emulsifiers, 0.2‑0.8% for amide lubricants, 0.03‑0.07% for sulfonic acid anionic surfactants, 0.1‑0.5% for antioxidants, and 0.1‑0.5% for anti-mold and fungicides 0.02‑0.04%, water balance. The invention uses vegetable oil, castor oil polyoxyethylene ether emulsifier, fatty alcohol emulsifier, antioxidant, anti-mold and fungicide, water, etc. as raw materials to make laser direct engraving protective agent, which can protect the Copper powder is cooled and moistened to protect and lubricate the copper layer. On the one hand, the bulkiness of the copper powder is increased by more than 20% after using the protective agent, which makes it easier to disperse and prevent the copper powder from bonding, melting and solidifying. On the other hand, it can effectively Reduce the oxidation and discoloration of the copper surface at high temperature, and increase the single burning time to more than 16 hours.

Description

technical field [0001] The invention relates to the technical field of electroplating copper layer surface treatment, in particular to a protective agent for laser plate direct engraving. Background technique [0002] In the gravure printing industry, in order to meet some special needs, such as anti-counterfeiting, special line version, leather version, wallpaper version, etc., the electroplated copper layer is ground and polished, then laser burns the pattern, and finally hard chrome plating is called in the industry. Laser plate; the plate roller with pattern etched by ferric chloride solution is called corroded plate. [0003] The active ingredients in the protective agent can ensure the smoothness of the copper layer at the burning position (mesh hole) during the laser burning process, and the laser burning process will generate high temperature. On the one hand, the copper powder burned at high temperature is in a molten state and adheres to the engraving head, which ...
