Definitions

  • the invention relates to a litho tape for electro-chemical Roughening consisting of a rolled aluminum alloy and a process for its manufacture.
  • Rectangular cast ingots are the primary material after milling the cast skin by hot and cold forming thin strips are rolled out.
  • the finish rolling happens usually with finely ground steel rollers, so that is standard a so-called mill finish surface is achieved.
  • the Semi-finished products are known as offset or litho strips and are usually used rolled up into coils.
  • the standard materials are pure aluminum (AA1050) and alloys of the type AlMn1 (AA3003, AA3103) for use.
  • the rolled strip is processed into printing plate supports by roughening the strip surface.
  • Mechanical, chemical and electrochemical roughening and combinations of these methods are known.
  • the electrochemical (EC) roughening is carried out as standard in baths based on HCl or HNO 3 ; the topography produced is characterized by fine round hollows ⁇ 20 ⁇ m in diameter; the printing plate is roughened all over and shows a structureless appearance (without streaking effects).
  • the roughening structure is protected by anodization, ie with a thin, hard oxide layer.
  • the printing plate carrier becomes an offset printing plate. The printing plates are exposed and developed.
  • the photo layer is baked at temperatures in the range of 220-300 ° C and glow times of 3-10 min; the thermal treatment makes the pixels resistant to abrasion, so that the printing plate is suitable for long runs.
  • the Al printing plate carrier should lose as little strength as possible, since soft plates can no longer be handled without kinks.
  • the finished printing plate is inserted into the printing press. It is important to clamp the plate exactly on the printing cylinder so that there is no freedom of movement during the printing process. If the printing plate is not ideally fixed and is therefore cyclically subjected to bending or torsion during printing, experience has shown that plate tears occur in the fast-running web offset printing machines ( plate cracking "). The cause is a fatigue fracture, which leads to the immediate interruption of the printing process. Al materials for offset printing plates must therefore have a sufficiently high fatigue strength or flexural fatigue strength so that" plate cracking "is avoided.
  • the object of the present invention is to develop a litho tape which has a high thermal stability, which can be roughened in EC processes based on HCl and HNO 3 just as well as pure aluminum, after the EC roughening a uniform, structureless (streak-free) appearance shows and which has a high fatigue strength perpendicular to the rolling direction. Furthermore, a method is to be specified with which the properties described above can be produced in the case of litho tapes.
  • the new litho tape is characterized by a narrowly limited Alloy range and through a controlled semi-finished product production with which a fine-grained, recrystallized hot strip is produced becomes. Further processing must also be controlled Conditions take place so that the one set in the rolling process Structural state is maintained.
  • a streak-free litho tape with high flexural fatigue strength Reaching across the rolling direction is next to the narrowly limited Analysis requires a controlled semi-finished product production.
  • a hot strip according to the invention After performing the features specified in claim 5 a) and b) is a hot strip according to the invention with the following Characteristic values generated (see Table 1).
  • Fig. 1a shows a schematic representation of the grain structure of the hot strip according to the invention in longitudinal section. You can see the dark colored globular recrystallized grains, which extend over more than 75% of the total hot strip thickness. The gray, elongated areas represent non-recrystallized grains.
  • Fig. 1b schematically shows the longitudinal section through a standard hot strip made from the alloy AA 1050; there is an inhomogeneous mixed structure which is partly roughly recrystallized, partly not recrystallized. In principle, the structure remains intact when further rolling; the homogeneous structure of the hot strip according to the invention prevents streaking effects on strip thickness.
  • the measurement of the RR value in hot strip enables in early control of the control - for the fatigue strength important - dissolved elements Fe and Mg; an RR value in the range of 10 - 20 guarantees the proportion of elements in solid solution, that in the finished rolled strip for a high Flexural fatigue strength in the transverse direction is required.
  • the Residual resistance ratio RR is a measure of that in the Al mixed crystal proportion of alloy in solid solution; the Measuring method for determining the RR value is in the publication Corrosion Science, Vol. 38, No. 3, pp. 413-429, 1996 described.
  • the hot strip is cold rolled according to claim 5 feature c).
  • On final annealing of the cold-rolled strip must be avoided, since the fatigue strength is due to softening annealing although it can be increased in the longitudinal direction (cf. U.S. Patent 4 435 230 / Furukawa Aluminum Co. and U.S. Patent 3,911,819 / Swiss Aluminum Ltd.), but in the critical transverse direction decreases.
  • the thermal stability is determined by measuring the strength tested in a tensile test after the litho tape had been at 240 ° C. for 10 minutes has been annealed. It is a standard glow test, which is common with printing plate manufacturers and in practice covers common stoving treatments.
  • the material after 240 ° C / 10min the material should have a higher thermal stability than AA 1050, namely Rm> 145 N / mm 2 .
  • Whether a litho tape can be roughened well or badly in the electrochemical treatment depends heavily on the respective process of the printing plate manufacturer. Therefore, one test criterion is not sufficient for evaluating the roughening behavior.
  • the three most important properties were tested here: the roughening behavior in the HCl bath, the roughening behavior in the HNO 3 bath and the tendency to streak.
  • Samples of 0.5 m 2 are roughened at constant temperature and constant flow conditions in an electrolyte of 7 g / l hydrochloric acid with an alternating current of 50 Hz.
  • the EC roughening takes place with different roughening charges in the range of 500-1500 C / dm 2 .
  • a roughening of the samples is usually achieved in this area: the plateau-like mill finish surface has disappeared and a full-surface trough structure has been created.
  • the samples are then classified according to the progress of roughening. For this purpose, a standard sample made of material AA 1050 is always checked and the test material is evaluated in each case in comparison to the standard.
  • the material should be roughened at least as well be like AA 1050, i.e. after the test described at least received a rating of +.
  • the EC roughening takes place with different roughening charges in the range of 500-1000 C / dm 2 .
  • a roughening of the specimens is usually achieved in this area, ie the bare-rolled surface with mill finish structure has disappeared and has been replaced by a surface-covering trough structure.
  • a standard sample Material AA 1050 is always checked along with the test material in each case compared to the standard.
  • the material should be roughened at least as well be like AA 1050, i.e. after the test described at least received a rating of +.
  • Macro etching can be used to check whether a litho tape shows the desired structure-free appearance after roughening.
  • the samples are treated in a freshly prepared macro-etching solution (500 ml H 2 O, 375 ml HCl, 175 ml HNO 3 , 50 ml HF, etching for 30 seconds at 25 ° C); the degree of streaking is then determined by optical inspection.
  • the new material should have a significantly higher bending number than AA 1050 and at least the bending number of AA 3103, namely a bending number> 1250 for 0.3 mm strip thickness.
  • the subsequent cold rolling can be done in different ways take place, as shown by way of example.
  • Example 1 the strip is produced with an intermediate annealing; the heating rate is 35 ° C / h, the annealing temperature 400 ° C and the annealing time 2 hours MT.
  • the strip is produced with intermediate annealing, the heating rate being 25 ° C./s, the annealing temperature 450 ° C. and the annealing time being 1 minute.
  • the strip is manufactured without intermediate annealing.
  • the final thicknesses are 0.3 mm each.
  • the band receives no more Annealing, but goes into the process of being cold rolled Printing plate production.
  • Table 2 shows that the strips with the alloy composition according to the invention meet the requirements in terms of thermal stability (Rm> 145 N / mm 2 ) and bending cycles in the transverse direction (> 1250) according to the production processes specified; They also have very good roughening behavior in the HCl and HNO 3 system, which exceeds the standard material AA 1050 in terms of roughening speed.
  • intermediate annealing examples 1, 2
  • the strips are completely without structure and achieve top marks in the streak test. But even when manufacturing without intermediate annealing (example 3), the roughened surface is still sufficiently structureless and streak-free.
  • Table 3 shows the properties of those previously used for offset printing plates used standard materials AA1050 and AA3103 listed. They differ from the tapes according to the invention essentially through analysis; the production of semi-finished products was carried out in the same way as for inventive examples 1, 2, 3rd
  • Examples 6 + 7 The standard material AA1050 (pure aluminum) does not meet the requirements with regard to thermal stability and bending fatigue strength in the transverse direction - with and without intermediate annealing.
  • AA 1050 with intermediate annealing the strip is rated well in the streak test; in the case of production without intermediate annealing (example 7), the roughened surface shows a streaked appearance.
  • higher charges are required for AA 1050 for area-wide roughening than for the examples according to the invention.
  • Example 8 The material AA 3103 used for offset printing plates is a single alloy which, due to an Mn content of approx. 1%, meets the requirements for strength and flexural fatigue strength.
  • the disadvantage of the material is that it cannot be used universally for EC roughening: roughening in the ENT 3 process is not possible and is therefore unusual; When the EC is roughened in the HCl process, a very high charge is required to achieve a homogeneous, comprehensive pickling tray structure. The streak test requirement is not met.
  • Table 4 shows the properties of litho ribbons for offset printing plates summarized, the materials containing Mg were produced, but otherwise in the analysis and / or the tape production differ from the inventive examples.
  • Examples 4, 5, 9 meet the requirement in the streak test. This is due to the fact that the strips here - just like Examples 1, 2, 3 according to the invention - were produced from a largely recrystallized hot strip. In addition, the following differences can be noted.
  • Example 4 was produced with the analysis and production according to the invention, but with a final annealing of 200 ° C./1 h.
  • the thermal stability is similar and the roughening behavior in both acid systems is just as good as for example 3 according to the invention.
  • the fatigue strength in the transverse direction does not correspond to the required level.
  • Example 9 differs from the analysis according to the invention in that it has a low Fe content of ⁇ 0.3%; the production is identical to example 3. It can be seen that the requirements - with the exception of thermal stability - are met. From this it can be concluded that a higher Fe content is required to achieve a sufficiently high thermal stability.
  • Example 5 differs from Example 3 according to the invention in that it has a low Fe content of ⁇ 0.3% and in the production which was carried out without intermediate annealing and with final annealing of the cold-rolled strip at 200 ° C./1 h.
  • This variant corresponds to a material that is described in US Patent 4,435,230 (Furukawa Aluminum Co.). According to the patent, it is characterized by good fatigue behavior (in the longitudinal direction) and good roughening behavior in the HCl process. It should be noted that the requirement for the fatigue strength in the critical transverse direction is not met and the desired thermal stability is also not achieved. The roughening behavior - as described in the patent - is good.
  • Example 10 is a material described in U.S. Patent 3,911,819 (Swiss Aluminum Ltd.). The alloy is primarily characterized by the addition of Cu. The material is attested to good fatigue behavior, which is understandable based on the analysis. The patent does not provide any information about the roughening behavior. - It was found that Cu additions> 0.04% in both AA 1050 and AA 3103 alloys have a negative effect on the electrochemical roughening. The Cu-containing material in Example 10 can only be used for purely mechanical roughening; it is unsuitable for electrochemical roughening in HCl or HNO 3 processes, since it does not achieve the required litho-tape qualities.
