Problems solved by technology

[0002] CTP plate has the advantages of high printing quality, short production cycle, no environmental pollution, remote plate transfer and on-demand printing, etc., so the application of CTP plate has been developed rapidly, but the aluminum alloy strip used for printing CTP plate base has surface quality Main internal defects such as poor quality, uneven chemical composition, coarse structure, and abnormal shape and size of the compound cause electrolytic corrosion performance to fail to meet high-quality printing requirements, and domestic aluminum substrates for CTP plates cannot be mass-produced. At present, most high-end CTP Plate base relies on imports to meet production needs

Abstract

The invention discloses a manufacturing method of an aluminium alloy strip used for printing a CTP (computer-to-point) substrate. By reasonably distributing hot rolling and cold rolling deformation, a better compound crushing effect and a dislocation distribution effect can be obtained, the grains are small, and the grain boundary quantity is increased, thus a tissue which is beneficial to electrolysis and can balance factors influencing the electrolysis can be obtained, and the mechanical properties are excellent.
