Definitions
- the invention relates to an aluminum strip for lithographic printing plate support consisting of an aluminum alloy, a method for producing an aluminum strip for lithographic printing plate support and a printing plate support.
- Print plate supports for lithographic printing from an aluminum alloy have to meet very high requirements for their suitability for today's printing technology.
- the printing plate carrier produced from an aluminum strip must be able to be roughened homogeneously, with mechanical, chemical and electrochemical roughening methods and combinations of the roughening methods described being used.
- the printing plates are often subjected to baking at 220 to 300 ° C for 3 to 10 minutes to cure the applied photoresist. In this baking process, the printing plate support should lose as little as possible in strength, so that the printing plate support continues to be handled properly. In the use of pressure plate carrier beyond the fatigue or play. Flexural fatigue strength of the printing plate support a role to guarantee a long-term stability of the printing plate support can.
- the printing plate supports used also made of an aluminum alloy of the type AA1050, but the roughening in the electrochemical roughening preferably used is poor, so that preferably an aluminum alloy of the type AA1050 are used.
- Printing plate supports made of an aluminum strip with the above-mentioned composition has now been found that, in particular for the preferably applied electrochemical roughening of the aluminum strip to achieve a homogeneous roughening a relatively high charge carrier entry is necessary, so that the roughening process is very costly.
- the mechanical properties of the aluminum alloy previously used for the production of aluminum strips for lithographic printing plate supports are in need of improvement. This relates in particular to the thermal stability of the printing plate supports after a baking process.
- a corresponding aluminum alloy is known from international patent application WO 02/48415 A1.
- With increased magnesium and manganese values of the aluminum alloy further problems have been found in electrochemical roughening.
- the object of the present invention is to provide an aluminum strip for lithographic printing plate supports from which printing plate supports having improved roughening properties and at the same time improved mechanical properties, in particular after a baking process, can be produced.
- a method for producing an aluminum strip for lithographic printing plate support and corresponding printing plate support will be specified.
- an aluminum strip consisting of an aluminum alloy in that the aluminum alloy has the following proportions of alloy constituents in% by weight:
- the aluminum strip according to the invention in spite of the high Fe content, on the one hand has very good properties with regard to electrochemical roughening of the strip and, on the other hand, improved mechanical properties, in particular after carrying out a burn-in process. This is all the more surprising as the experts until now had the opinion that only an Fe content of max. 0.4 wt .-% in an aluminum ribbon for lithographic
- the Mg content in the aluminum alloy increases the roughening speed in an electrochemical roughening process, but at an Mg content of greater than 0.3 wt%, the accelerated etching attack may result in an inhomogeneous roughening structure and the roughening process becomes problematic.
- the inventive Si content of 0.05 wt .-% to 0.5 wt .-% also affects the appearance of electrochemically roughened printing plate support. If the Si content is too low, electrochemical roughening results in too high a number of too small depressions in the aluminum strip. If the Si content is too large, the number of wells in the roughened aluminum band is too small and the distribution is inhomogeneous.
- the Cu content of the aluminum alloy according to the invention must, in order to avoid extremely inhomogeneous structures when roughening to max. Be limited to 0.04 wt .-%. This also applies to the proportion of titanium, which mostly passes through the grain refining materials into the melt of the aluminum alloy. Therefore, a limitation of the Ti content is on Max . 0.04 wt .-% necessary.
- the restriction of contamination of the aluminum alloy to individually max. 0.01% by weight and in total max. to 0.05 wt .-% leads to a further stabilization of the properties of the aluminum strip for lithographic printing plate support, in particular with regard to manufacturing tolerances of the composition of the aluminum alloy and their process properties.
- the aluminum strip according to the invention is very well suited for the production of lithographic printing plate supports, since this, in addition to very good roughening properties at the same time provides very good mechanical properties, in particular after the performance of burn-in.
- the cause is seen in the increased number of specific Fe- and Mn-containing precipitates, which in addition to the mechanical and thermal properties also positively influence the reactivity in the roughening of the aluminum alloy.
- the aluminum strip according to the invention has an Mn content in wt .-% of 0.008% ⁇ Mn ⁇ 0.2%, preferably from
- the tendency to inhomogeneity after electrochemical roughening can be further reduced at the same time significantly improving the thermal stability after baking.
- the roughening behavior of the aluminum strip according to the invention can be improved in that the aluminum alloy has a Ti content in wt .-% of max. 0.01%.
- the aluminum strip according to the invention has a yield strength RpO, 2 of at least 180 MPa and a tensile strength Rm of at least 190 MPa in the rolling direction and / or a yield strength RpO, 2 of at least 190 MPa and a tensile strength Rm of at least 200 MPa transverse to the rolling direction at room temperature.
- the aluminum strip according to the invention after a heat treatment of 240 0 C for 10 min. a yield strength RpO, 2 of at least 140 MPa and a tensile strength Rm of at least 150 MPa transverse to or in the rolling direction, then the aluminum strip according to the invention is particularly suitable for lithographic printing plate support for particularly high runs, since they should lose as little as possible after firing ,
- the aluminum strip according to the invention is further improved according to a further embodiment in that the bending fatigue strength of the aluminum strip in the rolling direction more than 3000 bending cycles, preferably more than 3200 bending cycles in the rolling direction.
- the stated number of bending cycles in the rolling direction reaches the aluminum strip according to the invention, in particular in the hard-rolled state, and thus significantly exceeds conventional aluminum strips in the hard-rolled state.
- the flexural fatigue strength was measured by taking samples with a length of 100 mm and a width of 20 mm from the aluminum strip, the longitudinal axis of the samples corresponding to the rolling direction. The samples were then subjected to alternating bending over a radius of 30 mm and the number of bends until breakage was determined.
- the number of bends is a measure of the stability of a pressure plate carrier made from the aluminum strip during the printing process. In the present case, the number of bending cycles was determined statistically from twelve samples. The erfindunoniae aluminum strip thus allows the production of printing plate supports with a particularly long service life.
- a further extended service life of pressure plate carriers produced from the aluminum strip according to the invention is achieved in that the bending fatigue strength of the aluminum strip after a heat treatment of 240 0 C for 10 min.
- the rolling direction of more than 3300 bending cycles, preferably more than 3400 bending cycles in the rolling direction.
- the cause of the increase in the bending cycles is seen on the one hand in the softening of the aluminum strip during the baking process, on the other hand, but also in the thermal stability of the aluminum strip according to the invention.
- an electrochemical roughening process of the aluminum strip which is usually carried out for the production of printing plate supports, can be improved by the aluminum strip having a fine-grained, globulitic-grained surface having more than 250 grains per mm 2 , preferably more than 350 grains per mm 2 .
- a fine-grained structure with the specified grain density produces a more homogeneous appearance when roughened or coated. Overall, this accelerates the roughening process.
- the grain structure can be achieved, for example, by the production method according to the invention with degrees of rolling that have been specially set after intermediate annealing during cold rolling to final thickness.

- a fine-grained surface can be provided so that a more homogeneous appearance after roughening is ensured.
- the final thickness of the aluminum strip is preferably 0.15 mm to 0.5 mm, in particular 0.15 mm to 0.35 mm.
- an aluminum strip optimized for the production of printing plate supports can be made available with an aluminum strip produced by the method according to the invention, since it has improved roughening behavior with improved heat resistance and improved strength values.
- the finished rolled aluminum strip is subjected to degreasing with an alkaline or acidic medium after rolling, and the degreased aluminum strip is electrochemically roughened.
- the roughening of the aluminum strip is preferably carried out in baths of nitric acid HNO 3 or hydrochloric acid HCl.
- electrochemical roughening can also be carried out in mixed acid solutions.
