Definitions

  • the invention relates to a method for producing a chemical-resistant protective layer for a rotary body having a base body of fiber-reinforced plastic according to claim 1 and a rotary body having a layer structure according to claim 6.
  • roller body made of fiber-reinforced, in particular carbon fiber reinforced plastic.
  • roller bodies for printing machines such as dampening rollers, ink rollers, plate cylinders, blanket cylinders, also for the sleeve technique, etc.
  • Printing auxiliaries are, for example, paints, dampening solutions, detergents and all substances which come into contact with the roll surfaces.
  • any fiber-reinforced material can only maintain its property profile if the matrix does not lose its adhesion to the fibers and there are no dimensional changes in the form of swelling or shrinking. Particularly feared is z.
  • the so-called delamination is connected as a result of the water absorption of the plastic matrix, with a dramatic decline in strength.
  • Coatings of fiber-reinforced plastics are known, in particular by thermal spraying, whereby the problem of adhesion promotion is given the greatest attention (see, for example, the DE 36 17 034 C2 or the DE 36 08 286 A1 ), while the chemical resistance of the coatings to protect the body so far at best imprecise or not treated.
  • the EP 0 514 640 B1 describes a process for coating fiber-reinforced plastic bodies by means of thermal spraying using an intermediate layer of thermosetting or thermoplastic resin dispersed with ceramic particles and ground after curing to provide for the actual functional layer of metal or ceramic plastic-free adhesion points of the same material.
  • the invention is therefore based on the object to produce a chemical-resistant protective layer of fiber-reinforced plastic bodies and to provide a rotary body with a base made of fiber reinforced plastic and such a protective layer, so that not only the protection of the body is guaranteed, but also a strong bond is given to an overlying, preferably applied by thermal spraying, wear and corrosion resistant functional layer.
  • the object underlying the invention is achieved by the features of method claim 1 and by the characterizing features of claim 8, ie the fact that the protected fiber-reinforced plastic component, the main body of a rotating body, is first protected with a layer of hard rubber, in the metal - or ceramic particles are dispersed with a dispersion content of 5 vol .-% - 80 vol .-%, these are ground and then the hard rubber layer with a metal and / or ceramic layer, preferably by thermal spraying, is coated.
  • the chemical-resistant intermediate layer made of hard rubber can be applied in a thickness of 160 ⁇ m up to 10000 ⁇ m, preferably from 500 ⁇ m up to 1000 ⁇ m, with NBR rubber coverings with 40 ° -80 ° Shore D, preferably 80 ° Shore D, for classic offset applications. be used advantageously.
  • EPDM rubber coverings of the same thickness or Shore hardness are particularly suitable for offset applications using UV-curing inks.
  • the metal or ceramic particles must be mixed in before the vulcanization in water vapor at 140 ° C - 160 ° C, for example by rolling or kneading.
  • the chemical-resistant intermediate layer ie the hard rubber coating, must be sanded until the dispersed metal or ceramic particles are also ground on the surface.
  • metal or ceramic particles are used suitably commercial spray powder, as it is used for thermal spraying.
  • the further coating of the fiber-reinforced plastic body provided with the sanded intermediate layer of hard rubber is preferably carried out depending on the intended use (as a dampening, color, conductive, tensile, weaving, or derusting roller, etc.), preferably by thermal spraying of suitable materials, such as e.g. Oxide ceramic on high-alloy chromium / nickel steel adhesive layer for dampening roller application or wear-resistant hard coating (WC / Co, WC / Ni Cr3C2 / NiCr, NiCrBSi) with guide roller application.
  • suitable materials such as e.g. Oxide ceramic on high-alloy chromium / nickel steel adhesive layer for dampening roller application or wear-resistant hard coating (WC / Co, WC / Ni Cr3C2 / NiCr, NiCrBSi) with guide roller application.
  • a pressure-functional functional layer by plasma spraying of high-alloy chromium nickel steel and subsequently applied by oxide ceramics, which is smoothed by grinding, polishing, brushing or scrubbing up to a roughness of Rz ⁇ 3.0 microns to the ground hard coating also preferably used as a dampening roller surface.
  • the functional layer of the fiber-reinforced plastic body protected with the ground intermediate layer can also be effected by other comparatively cold coating methods such as electroplating, chemical deposition, cathodic sputtering (PVD), sol-gel, etc., whereby chromium, nickel, copper, oxide ceramics or combinations thereof are deposited.
  • PVD cathodic sputtering
  • the result of this method is a rotary body with a base made of fiber-reinforced, in particular carbon fiber-reinforced plastic with a chemical-resistant intermediate layer of hard rubber applied thereto, which has a metal or ceramic dispersion content of 5% by volume to 80% by volume. and is covered with a particular Druckischen functional layer of metal and / or ceramic.
  • the rotary body can also be a printing-plastic sleeve (sleeve), which is provided with the inventively prepared chemical-resistant protective coating, and are mounted on a plate cylinder or blanket cylinder.
  • sleeve printing-plastic sleeve
  • the rotation body according to the invention may also be a screen ink roller, in which case the surface of the chemical-resistant protective layer consists of laser-scanned chromium oxide and thus fulfills the function of a screen inking roller for short inking units in offset, gravure and flexographic printing machines.
