Anti-corrosion water-based laser glue capable of being removed easily and ablated by laser

Abstract

The invention relates to environmental-friendly laser glue needed by a laser ablation method for photogravure. The laser glue is anti-corrosion and can be removed easily and ablated by laser. The laser glue comprises the following components in percentage by weight: 5 to 40 percent of water-based resin, 0 to 10 percent of cross-linking degree controlling agent, 0.2 to 40 percent of laser absorbent, 0 to 5 percent of laser sensitizer, 2 to 10 percent of antifreeze, 0 to 10 percent of quick-drying agent, 0 to 5 percent of pH regulator, 0 to 1 percent of flatting agent, 0 to 1 percent of defoaming agent, 0 to 1 percent of preservative, 0 to 5 percent of thickening agent, 0 to 5 percent of dispersing agent and the balance of deionized water. The water-based laser glue has the advantages of no environmental pollution, no harm to human body and no combustion explosion. The laser glue can also be used for manufacturing precision dials, brass plates, crafts and the like by a corrosion method.

Description

technical field [0001] The invention relates to an environment-friendly water-based paint (commonly known as water-based laser glue) required for gravure printing plate making by laser ablation. The laser glue has the properties of corrosion resistance, easy removal and laser ablation. Background technique [0002] Plate making is necessary before gravure printing. At present, there are two main types of gravure plate making: electronic engraving and laser plate making. Electronic engraving is controlled by an electronic computer, and a sharp diamond knife is used to carve a tapered shape on the copper surface of the gravure roller according to the image signal. Mesh hole. The laser plate making method is divided into two types: laser engraving method and chemical etching method. The chemical etching method mainly includes two methods: laser exposure method and laser ablation method. The laser ablation method can produce various shapes of cells and lines. The cells are deep...

Problems solved by technology

[0012] The laser plate-making adhesives currently used in my country are all imported and solvent-based. Although they have the advantages of good abrasion resistance, easy to be ablated by lasers, and easy to be removed by solvents, they are flammable and explosive, and have a lot of hazards. Disadvantages of volatile solvents for the environment and human health

For this reason, a water-based laser glue must be developed, which has the advantages of not polluting the environment, harming the human body, and not burning and exploding. However, due to the high technical difficulty, it has not yet come out.
