Definitions

  • the invention relates to a process for the formation and application of a hydrophilic coating which is highly lubricious in the moist state on a molded part made of plastic or metal, in particular a razor or razor blade unit, in which a solution containing a water-soluble polymer, in particular polyvinylpyrrolidone, is applied to the molded part and cured there becomes.
  • the invention further relates to a razor or a razor blade unit with at least one razor blade held on a blade support and a surface adjacent to the razor blade that sweeps over the skin of the user during the shaving process, in particular a cap made of plastic, such as polystyrene or ABS, or of metal that is coated with a the lubricity-increasing device is provided.
  • a razor made of plastic in which at least one razor blade is arranged between a razor blade support and a cap.
  • the shaver head has an integral solid and water soluble shaving aid.
  • the shaving aid is provided in the form of a strip made of the solid but water-soluble material, the strip being arranged in an adjacent position to the razor blade and being attached either to the blade support or to the cap.
  • a microencapsulated silicone oil, polyethylene oxide, a nonionic polyacrylamide or a polysaccharide is provided as the water-soluble material.
  • a disadvantage of the known razor is that the substance acting as a lubricant detaches from the carrier body and is deposited on the skin of the user in the form of a film. There is thus the risk of causing skin irritation as well as the need to rinse off the lubricating film that dries on already shaved skin, which can be difficult depending on the hardness of the water available.
  • the construction of the razor with a plastic strip arranged in a recess is complex and it is not possible to move the strip into the actual vicinity of the cutting edge of the razor blade. In principle, therefore, the known sliding strip is only to be positioned at a location on the shaving apparatus which is unfavorable for the desired usage properties.
  • a molded body made of a polymeric substrate and a coating layer applied to this substrate is also known, in which it consists of a polyvinylpyrrolidone-polyurethane interpolymer.
  • Various applications, such as contact lenses, catheters, peristaltic pump chambers, condoms and the like, are mentioned for such a shaped body, in which it is desirable to use a material, such as polyurethane, an acrylic acid polyester or a vinyl resin, which has a lower content in the moist state Has a coefficient of friction that is otherwise the case with such materials is possible.
  • a material such as polyurethane, an acrylic acid polyester or a vinyl resin, which has a lower content in the moist state Has a coefficient of friction that is otherwise the case with such materials is possible.
  • such requirements do not exist with conventional shavers and it is also not common to use such materials, in particular a polyurethane.
  • the razors and razor blade unit are made of polystyrene, the properties of which are not comparable.
  • a coating applied by the process according to DE-PS 28 28 617 would not adhere to polystyrene. It is proposed there that a solution of a polyisocyanate is applied to the substrate and, after the solvent has evaporated, a solution of polyvinylpyrrolidone is applied to the substrate treated in this way, after which the solvent is evaporated to give a polyvinylpyrrolidone-polyurethane interpolymer.
  • the invention has for its object to improve a method of the type mentioned while avoiding the above disadvantages in such a way that the production of molded parts made of plastic or metal, in particular razors or razor blade units or their parts, high lubricity is possible in the moist state, the The coating also adheres well to polystyrene or ABS or metal and should be applied and hardened in a short time.
  • the invention is based on the objective of improving the sliding properties of a razor, particularly in the area close to the blade, in a way which prevents substances in the manner of a lubricant from depositing on the skin of the user.
  • the solution to be applied to the molded part consists of the water-soluble polymer, in particular poly-N-vinylpyrrolidone or a copolymer thereof, one or more radically polymerizable vinyl monomers and a photoinitiator which decomposes into free radicals when irradiated and that the applied one Solution for curing is exposed to UV radiation.
  • the solution then hardens quickly to a well-adhering coating of controlled layer thickness, which has a greatly reduced coefficient of friction on contact with the skin when wet.
  • the solution preferably contains 0.1 to 90% by weight of polyvinylpyrrolidone, in particular 5 to 30% by weight of polyvinylpyrrolidone, based on the vinyl monomers used.
  • the average molecular weight of polyvinylpyrrolidone can be different values from 15,000 to 800,000 g / mol, preferably 200,000 to 500,000 g / mol.
  • copolymers of pyrrolidone with, for example, maleinates or acrylates in the sense of the invention can also be used.
  • Other water-soluble polymers such as polyvinyl alcohol, polymers containing polyacrylamide, polysaccharides or polyethylene oxide, are also suitable as additives.

  • examples are cyclic or open-chain ether groups containing acrylic acid esters or methacrylic acid esters, such as esters of mono- or poly-ethoxylated or propoxylated C1 - C20 alcohols, THF-carbinol acrylate or THF-carbinol methacrylate, hydroxyalkyl esters, such as 2-hydroxyethyl acrylate, 2-hydroxyethyl methacrylate, 2-hydroxypropyl acrylate Hydroxypropyl methacrylate, N, N-dimethylamino-2-hydroxyethyl acrylate, N, N-dimethylaminoethyl metharylate or salts thereof, such as N, N, N-trimethylammonium-2-ethyl methyl acrylate
  • polyester resin systems contain maleic acid or fumaric acid and z.
  • the hydrophilic vinyl monomer mixtures preferably contain from 0 to 80% by weight, in particular 0.5 to 50% by weight, of hydrophobic monomers, such as methyl methacrylate, butyl acrylate, ethyl acrylate, cyclohexyl acrylate or ethyl hexyl acrylate.
  • hydrophobic monomers such as methyl methacrylate, butyl acrylate, ethyl acrylate, cyclohexyl acrylate or ethyl hexyl acrylate.
  • Urethane-modified acrylic and methacrylic esters can also be used, which in a known manner, for. B.
