Embodiment
The meaning that the following describes ingredient in allautal for planographic plate of the present invention reaches its reason that is limited.
Mg, its major part is solid-solubilized in the aluminium, plays a part to improve the intensity and the heat-resisting property of softening.So-called intensity is meant as press plate with supporting mass tensile strength at normal temperatures, and the preferable range in the middle of practical is more than 160MPa.The heat-resisting property of softening is also referred to as extra-heat-endurance, is 0.2% yield strength after the temperature that is heated to about 280 ℃, required scope when being practicality more than the 90MPa.The preferred content of Mg is discontented with at 0.1% o'clock in 0.1～0.3% scope, its effect deficiency, and greater than 0.3% o'clock, the homogeneity of the indenture in surface coarsening is handled reduced, and is easy to generate the pollution of non-image portion.
Zn is the same with Mg, and major part is solidly soluted in the aluminium, but different with Mg, is not the effect that improves intensity and softening resistance, but exerts an influence to being formed on the lip-deep oxide film thereon of aluminium.Be formed in the lip-deep oxide film thereon of aluminium, the oxide film thereon that has the oxide film thereon (natural oxidation tunicle) that forms when being placed on room temperature and form when in manufacturing processed, heat-treating, Zn all exerts an influence to both.
That is, in containing the aluminium alloy of Mg, particularly handle by homogenizing, heating during hot rolling, thermal treatments such as process annealing form the oxide film thereon based on the oxide compound (MgO is an oxide compound) of Mg easily, because this oxide film thereon is activity and porous, so, in the electrolytic surface roughening treatment, good with the wetting property of treatment solution, promote surface coarsening, but conversely, indenture becomes inhomogeneous easily.By containing Zn, can improve the ununiformity of this surface coarsening structure, have the function that suppresses the sensitization that the Mg oxide compound causes.The preferred content range of Zn is, greater than 0.05%, smaller or equal to 0.5%, 0.05% when following, above-mentioned effect is little, when content greater than 0.5% the time, suppress to increase by the active effect that the Mg oxide compound causes, it is inhomogeneous that surface coarsening becomes, and, generate thick intermetallic compound easily, form thick indenture when electrolysis treatment, it is inhomogeneous that surface coarsening further becomes.The preferred content range of Zn is 0.06～0.5%.
The content of Mg and the content of Zn, the preferred relation that satisfies 0.4 * Zn%≤Mg%≤4 * Zn%, when 0.4 * Zn%＞Mg%, because with respect to Mg, Zn measures superfluous, so the activity that the Mg oxide compound is produced suppresses the effect increase, the formation of indenture becomes inhomogeneous during electrolysis treatment, and it is inhomogeneous that the formation of uneven surface becomes easily.When Mg＞4 * Zn%, with respect to the Mg amount, the Zn amount is very few, and it is little to suppress the active effect that caused by the Mg oxide compound, and in this case, the indenture during electrolysis treatment forms and becomes inhomogeneous, and it is inhomogeneous that the formation of uneven surface becomes easily.
Fe generates the Al-Fe series intermetallic compound, in addition, coexists with Si, generate the Al-Fe-Si series intermetallic compound, by the dispersion of these compounds, the recrystallized structure miniaturization, these compounds become the starting point that indenture takes place, and the formation of the indenture when making electrolysis treatment evenly and imperceptibly distributes.The preferred content of Fe is in 0.2～0.6% scope, and the distribution of compound becomes inhomogeneous during less than 0.2%, and the formation of the indenture during electrolysis treatment becomes inhomogeneous.But when greater than 0.6% the time, generate thick compound, the homogeneity of surface coarsening structure reduces.
Si and Fe coexistence generate the Al-Fe-Si series intermetallic compound, and by the dispersion of this compound, in the crystal structure miniaturization, these compounds become the starting point that indenture takes place, and the formation of the indenture when making electrolysis treatment evenly and imperceptibly distributes.The preferred content of Si is in 0.03～0.15% scope, and when less than 0.03%, the distribution of compound becomes inhomogeneous, and the formation of the indenture during electrolysis treatment is inhomogeneous.When greater than 0.15% the time, generate thick compound, and separate out monomer Si easily, reduce the homogeneity of uneven surface structure.
Cu is easy to be solidly soluted in the aluminium, in the scope that (does not comprise 0%) below 0.03%, has the effect with the indenture miniaturization, but when greater than 0.03% the time, it is thick and inhomogeneous that the indenture during electrolysis treatment becomes easily.In addition, in the present invention, from being about 5～100ppm (0.0005～0.01%) for the Cu that sneaks into the living gold that content adopted that obtains aforementioned Fe and Si amount.
Ti becomes fine with ingot structure, with the miniaturization of crystallization crystal grain, and its result, the formation of the indenture when making electrolysis treatment becomes evenly, produces striped when preventing to carry out the processing as press plate.The preferred content scope of Ti is 0.003～0.05%, and during less than 0.003%, its effect is little, and content generated the thick compound of Al-Ti system greater than 0.05% o'clock, and it is inhomogeneous that the surface coarsening structure becomes easily.In addition, for the miniaturization of ingot structure, when adding B with Ti, preferably, the content range that makes Ti is below 0.01%.
Mn has the function that improves the intensity and the heat-resisting property of softening.The preferred content scope of Mn is, the scope greater than 0.05% to 0.3% is 0.05% when following, its effect is little, when greater than 0.3% the time, generate thick Al-Fe-Mn system or Al-Fe-Mn-Si series intermetallic compound easily, the surface coarsening during electrolysis treatment becomes inhomogeneous.The preferred content range of Mn is 0.06～0.3%.
In addition, in aluminium alloy plate of the present invention, when containing Pb: down in equaling 100ppm, Cr: smaller or equal to 100ppm, In: smaller or equal to 50ppm, Sn: smaller or equal to 50ppm, Ni: smaller or equal to 50ppm, Ga: smaller or equal to 300ppm, V: during smaller or equal to 200ppm, can not undermine effect of the present invention.
Lithographic plate supporting mass according to the present invention is with the manufacturing of aluminium alloy plate, after the aluminium alloy cast ingot homogenizing described in any one in the aforementioned techniques scheme 1～3 is handled, by carrying out hot rolling, cold rolling carrying out.In cold rolling process, also can carry out process annealing.For example, carry out homogenizing and handle under 400～600 ℃ temperature, carry out beginning hot rolled hot rolling under 350～600 ℃ temperature, the rolling degree of finish with 50～98% scope after hot rolling carries out cold rolling.In underway when annealing, after hot rolling, for example the temperature at 350～550 ℃ keeps under the condition in 0～30 second in continuous annealing furnace, carry out process annealing after, the rolling degree of finish of the scope with 50～98% carries out cold rolling.In addition, after hot rolling, carry out cold rollingly, in cold rolling process, carry out after the aforementioned process annealing, implement pinch pass.
