Description
Technical Field
The invention relates to the field of gravure printing, in particular to polishing paste for a copper-plated layer of a gravure printing cylinder and a preparation method thereof.
Background
The intaglio printing plate is composed of pits corresponding to the original pattern and the surface of the printing plate. When printing, the ink is filled into the pits, the ink on the surface of the printing plate is scraped by the doctor blade, and the printing plate is in certain pressure contact with the printing stock to transfer the ink in the pits to the printing stock, thereby completing printing. Most of the printing plates for the recent intaglio printing are manufactured on the surface of a round cylinder, and a round-to-round printing mode is adopted, wherein an impression cylinder is usually arranged on the upper part, and a printing plate cylinder is arranged on the lower part. The lower portion of the plate cylinder is immersed in an ink tank from which the plate surfaces take ink (also by ink-jet from an ink pump or by ink transfer from an ink roller immersed in the tank). A thin steel sheet scraper is arranged above the ink groove and pressed on the surface of the printing plate cylinder to scrape ink (wiped by a wiping roller rotating reversely) on the non-image-text position on the printing plate surface. The ink retained in the ink holes (or lines) for printing text is transferred to the paper (plastic film, aluminium foil, etc.) passing through the tangent position of two rollers, so printing text. The gravure printing cylinder is generally made of cheap and strong steel or aluminum, then a copper coating which is easy to engrave is attached to the surface of the gravure printing cylinder, and the copper coating is engraved to form a printing plate, and in order to prolong the service life and reduce the abrasion, the copper printing plate is also plated with wear-resistant and corrosion-resistant chromium metal.
The copper coating of the gravure printing cylinder is generally prepared by an electroplating method, although the processing efficiency is high, the problems of fine unevenness of the metal surface, low surface smoothness and the like exist, polishing is required to be carried out before engraving plate making to improve the smoothness, and because the copper coating is thin, the conventional metal surface polishing processes such as oxidation or acid chemical polishing and the like are adopted, the smoothness can not meet the requirements, and the copper coating is easy to damage. The chinese patent application 200580020350.3, which uses electrolysis to polish, has a problem that it is not easy to control the polishing amount although the effect is high. At present, the surface polishing of the copper-electroplated layer of the gravure plate mainly adopts polishing paste for mechanical polishing, the used polishing paste is divided into water-based polishing paste and oil-based polishing paste, the water-based polishing paste takes water as a solvent, is environment-friendly and odorless, has no harm to human bodies, but has larger use amount, general light-emitting performance and easy residual black grease on workpieces. The oily polishing paste has good gloss, small using amount and no residue on the surface of a workpiece, but contains volatile organic solvent and has odor, and the oily polishing paste is harmful to human bodies after being used for a long time. Chinese patent application 201811490670.0 discloses an emulsion type polishing paste for copper layer of gravure and its preparation method, firstly weighing 35% -55% of water, heating to 80 ℃, then adding 1% -4% of octadecanoic acid, 2% -5% of paraffin and 3% -6% of natural grease, after completely dissolving, adding 30% -50% of abrasive and 0.1% -0.5% of auxiliary agent, fully stirring uniformly, and cooling. Wherein the abrasive is 3000-mesh common abrasive such as silicon carbide, brown fused alumina, white fused alumina and the like, and the auxiliary agent is surfactant such as TX-10, OP-10, quaternary ammonium salt, sodium dodecyl sulfate and the like. The emulsion type gravure copper layer polishing paste prepared by the method has the characteristics of small smell and no harm to human bodies of aqueous polishing pastes, and also has the characteristics of good gloss of oily polishing pastes, small using amount, no residue on the surfaces of workpieces and the like. However, in the actual use process, the problems of easy bottom deposition and low polishing efficiency of the abrasive exist, and because the formula selects natural grease which is easy to oxidize and deteriorate, the storage life is too short, and the polishing speed needs to be controlled during use, such as high polishing speed, higher temperature of a copper coating and polishing paste, easy oxidation and deterioration of the natural grease, easy oxidation and blackening of the copper coating and generation of pungent odor, so that the polishing efficiency is low at the same time.
