Abstract

The invention provides a method for preparing a flexo printing ceramic anilox roller, which comprises the following steps of: 1) dissolving sodium tetraborate, ethylene diamine tetraacetic acid, sodium silicate and sodium hydroxide into water to prepare electrolyte, adding additives and discharging stabilizers into the electrolyte, and mixing uniformly to prepare electrolytic solution; 2) polishing and cleaning an Al alloy roller; 3) putting the Al alloy roller into the prepared electrolytic solution, connecting DC or pulsed high-voltage power supply anode with the Al alloy roller, connecting the cathode with a copper electrode plate, electrifying to perform the electrolytic oxidation operation, making the temperature of the electrolytic solution maintained below 40 DEG C, and preparing a dense Al2O3 ceramic layer on the surface of the Al alloy roller through micro discharge oxidation on the surface of the Al alloy; and 4) taking the Al alloy roller out, cleaning, naturally drying, polishing the oxidized surface, and carving to prepare the flexo printing ceramic anilox roller. The method for preparing the flexo printing ceramic anilox roller can guarantee the thickness, hardness, intensity and abrasion resistance of the anilox roller ceramic layer, and has the advantages of simple process and less environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of printing, and in particular relates to a method for preparing a ceramic anilox cylinder in situ by using plasma electrolytic oxidation technology. Background technique [0002] The anilox roller is the heart of the flexographic printing machine. At present, there are mainly two types of metal anilox roller and ceramic anilox roller. Anilox rollers are relatively prone to mesh clogging; ceramic anilox rollers are more durable. At present, known ceramic anilox rolls are manufactured by plasma thermal spraying, which is a method of sending coating materials (powder or wire) into some heat source (electric arc, combustion flame, plasma, etc.) ) is melted and sprayed onto the surface of the base material by high-speed airflow to form a covering layer. However, its process and production equipment are complicated, the production cost of ceramic anilox roller is high, and the coating and substrate are mechanic...
