Embodiment Construction

[0030] Figure 1a A schematic sectional view of a preferred embodiment of a drum lining 1 according to the invention is shown. The lining 1 has a base 2 , which is preferably made of stainless steel and alternatively of aluminium, titanium, steel or plastic, and a wear-resistant and corrosion-resistant coating 3 . The coating 3 comprises a sol-gel matrix 4a of crosslinked nanoparticles, with microparticles 5 embedded in the matrix 4a.

[0031] Such sol-gel matrices can be produced or constructed in a conventional manner, preferably according to the matrices disclosed in DE 19957325 A1. Preference is given to using the product "H5055" from FEW Chemie GmbH, Bitterfeld-Wolfen, for the nanosols. However, during the production according to the invention, the particles 5 or the corresponding raw materials of the particles 5 can additionally be dispersed in contrast to known methods. In contrast to known layers, the layer produced according to the invention has the particles embedd...

Abstract

A method for producing a structured surface making contact with printing material, preferably a cylinder cover, includes producing a structured coating having microparticles on a substrate, preferably a stainless steel plate. The microparticles are encased antiadhesively and agglomerated by adsorption of nanoparticles, and the agglomerates being produced are fixed in a sol-gel matrix. A surface produced in this way has a structured coating on a substrate and the coating has microparticles. The coating has agglomerates fixed in a sol-gel matrix and including microparticles encased antiadhesively by adsorption of nanoparticles and preferably formed of silicon carbide. The surfaces advantageously have a self-repair function since, in the case of abrasion of structural elevations, the antiadhesive casings of the microparticles are exposed and the antiadhesive property of the coating is maintained.

Description

technical field [0001] The invention relates to a method with the features of the preamble of claim 1 and a method with the features of the preamble of claim 4 . The invention also relates to a structured, substrate-contacting surface having the features of the preamble of claim 5 and to a use as claimed in claim 10 . Background technique [0002] Printing materials such as paper, cardboard or film are conveyed and processed in machines of the so-called graphic industry (print preparation, print production and postpress processing). The conveying of the printing material in the printing press can be carried out by means of a rotating cylinder which for this purpose has a surface which contacts the printing material, preferably in the form of a replaceable cylinder lining ("jacket"). The surfaces generally have two properties: on the one hand they are anti-adsorption (ink, varnish and dirt repellent) and on the other hand they are wear-resistant due to the usually very hard ...
