Title: Improvements in or relating to methods for increasing the anti-corrosive properties and accelerating the drying, of coatings of paint or printed surfaces
IPC: B41F23/00
Filed: 1954-11-12
Abstract: 762,338. Printing processes: finishing paper. LUEDER, H. Nov. 12, 1954, No. 32921/54. Class 100(2) [Also in Group XIIIJ A method of increasing the resistance to corrosion, and for the rapid drying of coatings of paint on freshly printed surfaces consists in subjecting the paint or ink to the effect of self-maintained stabilized elertric surface discharge during or following the application. The discharge is maintained between spaced electrodes and is continuous when D.C. is used and passes during at least one half cycle when' A.C. is used. The surface of the layer of paint or ink is disposed at the boundary of the steep rise in potential in the vicinity of the cathode so that polymerization or aggregation of the molecules of paint or ink takes place and forms a hard film on the surface. In the form of Fig. 1 the discharge passes from a flat metallic electrode 3, situated in close proximity above the layer of paint or ink, to the carrier 1 where this is of metal. When the carrier is non-conductive a second flat electrode 2 is provided underneath the carrier. The discharge is stabilized by the provision of at least one layer 6 of high resistance, e.g. an anodized surface of an aluminium electrode. The discharge may take place during the printing operation as shown in Fig. 2, the high voltage being applied between the forme 8 and the impression cylinder 11. The paper 14 is separated from the cylinder by an insulating layer 13. The forme 8 is insulated from the bed 9 by a sheet 10. A similar arrangement is described for a platen printing machine, the forme again being insulated from the machine frame and the paper separated from the platen by a highly resistive layer. A switch may be associated with the operating mechanism so that the high voltage is only applied when the platen approaches the closed position. Following the electrical treatment the paint or ink may be subjected to a heat treatment to increase further the effect of the electrical. The paint or ink may be formed with a binding agent prepared by treatment of oil in a Siemens tube instead of by the usual boiling process.
