Definitions

  • the present invention relates to a method for the protection of normally under water, especially under seawater, surfaces from fouling.
  • the invention thus achieves the above objects with a method of protecting normally submerged surfaces from fouling, wherein a deformable, self-adhering film is provided, flocked and adhered to the surface. Since the film is deformable, it can also be glued accurately on curved surfaces such as ship hulls. A coating of
  • Deformable, self-adhesive films for protection against fouling are known per se. However, these are equipped according to the prior art with the smoothest possible surface in order to reduce the adhesion of fouling organisms and to ensure a low flow resistance. Suitable materials are all sufficiently abrasion-resistant, salt water-resistant and UV-stable plastics.
  • Preferred materials for the films according to the invention are polyvinyl chloride (PVC), polyurethanes (PU), butadiene and isoprene-based polymers, polyolefins such as polyethylene (PE) and polypropylene (PP). Particularly preferred are polymers based on vinyl monomers, in particular polyvinyl chloride (PVC). Also suitable are films based on PVC and or ethylene vinyl acetate (EVA).
  • the film may in known manner have additives and additives which are used in the usual amounts.
  • plasticizers, stabilizers and, if desired, pigments and / or dyes are preferably included.
  • pigments and / or dyes are preferably included.
  • S-PVC are e.g. 60-70% by weight PVC; 5 - 10 wt.% EVA; 15-25% by weight polymer plasticizer, 2.0-3.0% by weight barium / zinc stabilizer; 5 - 10 wt .-% modifier and 0.5 - 1, 0 wt .-% light stabilizer typical.
  • the amount of pigments / dyes depends on the color desired. It is possible to provide biocidal agents in the sheet material.
  • Deformable means in the context of the present invention that the film has an elongation at break of at least 200%.
  • the 2% module is from 15 to 25 N / 15mm.
  • the stretching force is in the range of 25 to 40 N / 15mm. Elongation at break, 2% modulus and yield strength are measured in accordance with DIN EN 527 3/2/200.
  • Multilayer films which may have two, three or more layers, are obtained by coextrusion, direct extrusion or lamination. These methods are known to the person skilled in the art.
  • the film is coated with a pressure-sensitive adhesive so that it can be glued directly to the surface to be protected.
  • a pressure-sensitive adhesive Suitable in principle are all adhesives that show sufficient resistance to seawater and good adhesion both with the film and with surfaces of metal, wood, paint, etc. Preference is given to using a pressure-sensitive adhesive based on acrylates. In a preferred embodiment, the pressure-sensitive adhesive becomes a biocidal
  • Active ingredient added for example CU2O, an isothiazolinone and / or a pyrithione.
  • fibers for flocking adhesives and fibers are used, which are suitable for prolonged contact with water.
  • fibers for example, polyamide and polyester fibers are well suited. But also copper fibers, silver fibers or fibers with biocidal active ingredients in and / or on the fiber are advantageous. Fibers with biocidal active ingredient are known per se and have hitherto been used in medicine. According to the invention, fibers having a content and / or a coating with copper (I) oxide, isothiazolinones, pyrithiones and other biocidal, in particular algicidal, active compounds known per se are suitable. The incorporation of the active substance or substances in the fiber provides for an extension of the duration of action, since superficially lost by washing out lost drug from the fiber interior can diffuse. It is also possible to incorporate a first active ingredient in the fiber and another as a coating
  • fiber blends are used to obtain a batt with both hydrophobic and hydrophilic fibers.
  • the surface tension (measured according to DIN 53364) should be> 50 dyn, preferably> 60 dyn for the hydrophilic fibers and ⁇ 30 dyn, preferably ⁇ 20 dyn for the hydrophobic fibers.
  • Typical fiber lengths are from 0.1 to 8 mm, preferably from 0.3 to 5 mm and more preferably from 0.5 to 3 mm.
  • the fiber thickness should be in the range of 1, 5 to 100 dtex, preferably 2 to 50 dtex for polymer fibers and 5 to 100 dtex for metal fibers.
  • Preferred diameters are from 10 to 100 .mu.m, preferably from 30 to 70 .mu.m.
  • the flocking takes place with fiber densities in the range of 100 to 500 fibers / mm 2 , preferably from 150 to 250 fibers / mm 2 .
  • seawater resistant adhesives are selected, which are matched to the film.
  • PVC films for example, plastisols, which are customary for the production of flocked T-shirts, are suitable.
  • a typical recipe includes PVC, plasticizer, filler and
  • a biocide is added to the adhesive in which the fibers are anchored, e.g. Copper 1-oxide or an isothiazolinone such as 4,5-dichloro-2-N-octylisothiazolin-3-one. Also mixtures of biocides are possible.
  • the pressure-sensitive adhesive self-adhesive is first equipped with the pressure-sensitive adhesive self-adhesive.
  • the pressure-sensitive adhesive is / is preferably covered with a release liner, eg siliconized paper.
  • the self-adhesive film is then coated with the adhesive to anchor the fibers and then flocked in a conventional manner.
  • the film is then usually wound on rolls and stored.
  • the surface is, if necessary, cleaned to remove adhering fouling and / or dirt.
  • the surface should be clean, free of grease and dry.
  • the film is, optionally after cutting and / or peeling off the Releaseliner, placed on the surface and pressed.
  • the film is preferably glued to shock. Gaps between adjacent film webs can be easily and quickly closed by appropriately cut pieces of film. A coating with adhesive is not necessary, so that there is no danger with the adhesive to glue the fibers in the already attached flocked films. It is also possible to form one edge of the film in a narrow strip without fibers and to glue the film with an overlap. In a further variant, it is conceivable that the fibers are removed after sticking in a strip bridging the shock and the shock is covered with a strip of flocked film. The strip may have the same structure as the film or else e.g. have a higher concentration of biocide or biocide at all.

  • Sheets Nos. 1, 4, 5, 9, 10 and 11 were stuck on metal sheets and the antifouling effect was examined.
  • the panels were attached to the circumference of rotatable discs, which were arranged in Southeast India in the sea. The discs are either rotated continuously for the examination or rotated alternately for one month and not rotated for one month. During the rotation, the speed of rotation and the circumference of the slices for the panels results in a speed of passing water of 20 knots (about 38 / hour). Once a month, the slices with the slices are taken out of the water and the surface examined for growth. A photo is taken, the number of barnacles counted and a flock of algae and other marine animals
