Problems solved by technology

It needs to be dried twice, and it also needs to be coated with anti-corrosion paint on the back and baked and cured at high temperature. Each time it takes about 24 hours to dry. Both contain a large amount of solvents, and the coating process will pollute the environment and cause harm to the health of operators, so it is necessary to improve the production process of magnesium alloy etching plates

Embodiment 1

[0034] 1000mm×500mm×7.0mm pre-coated magnesium alloy etching plate production process, such as figure 1 Shown:

[0035]Qualified 7.3-7.5mm thick AZ31B magnesium alloy rolling strip (mass percentage content of manganese is less than 0.25%, calcium content is 0.002%, grain size≤10μm) is cut to a width of 500mm and The length is 1000mm, and the tolerance of length and width is ±3mm. Then stack them together and put them into a box-type aging furnace, apply a uniform force, heat the aging furnace to 280°C, store for 4 hours, and then cool with the furnace.

[0036] After aging, the magnesium alloy plate is sanded with an 80-mesh sander until the thickness is between 7.10 and 7.15 mm, and then sanded with a 240-mesh and 600-mesh sander until the thickness is between 7.01 and 7.07 mm. The plate after sanding is directly sent to the washing and drying machine for washing and drying, and the drying temperature is set at 150°C; this process must ensure that the surface roughness of t...

Abstract

The invention discloses a production method of a magnesium alloy etching plate by using a protective film instead of back anticorrosion paint. The method includes the steps of: cutting or sawing a magnesium alloy etching plate base material and successively performing aging, sanding and/or polishing treatment, cleaning and drying treatment for the first time, surface treatment of front surface, cleaning and drying treatment for the second time, sun-drying or drying for the third time, photosensitive ink coating on the front surface, baking and standing treatment, covering of a whole shading film on the front surface and covering of a protective film on the back surface, thus producing a finish product of the magnesium alloy etching plate. The magnesium alloy etching plate base material isAZ31B magnesium alloy and the protective film is a single-surface-glued plastic thin film. The production method reduces the sun-drying times, roll-coating of the back paint and drying steps, shortensproduction time and increases production efficiency, reduces investment on manpower and equipment, reduces environment pollution, is energy-saving and environment-protective, and has great social andeconomic benefits.

Description

technical field [0001] The invention relates to a production method of a magnesium alloy etching plate, relates to a magnesium alloy material and its application in the field of printing and plate making, and specifically relates to a production method of a magnesium alloy etching plate in which a protective film is used instead of anti-corrosion paint on the back. Background technique [0002] Magnesium alloys are widely favored by various industries due to their series of advantages. Among them, the demand for magnesium alloy sheets in the printing field is mainly reflected in bronzing printing and embossing, that is, magnesium alloy etching plates and magnesium plates. At present, there is a wide demand for magnesium plates in the printing field, and the demand is increasing rapidly. As early as 40 years ago, magnesium alloy plates began to be widely used in the printing field, but they were mainly concentrated in European and American countries. In China, copper plates a...
