Definitions

  • the present invention relates to an organic based lacquer/ varnish or coating in the form of organic based gel coatings as defined by the preamble of claims 1 and 8.
  • the present invention further relates to the manufacture of lacquer/ varnish or coatings as defined by the preamble of claims 9, 10, 11 and 17 respectively.
  • the present invention relates to utilization of such organic based lacquer/ varnish or such coating as a protective coating on surfaces of aluminium or steel, particularly of rolled aluminium.
  • the present invention relates to a substrate comprising a coating of above mentioned type. (In the following we will generally - of practical reasons - refer to lacquers/ varnishes as lacquers only).
  • EP Al 0 555 052 describes a fluid mixture comprising an acryl monomer, silica particles and at least one initiator for ultraviolet curing of said mixture, as well as a component to inhibit decomposition of the mixture caused by the ultraviolet radiation.
  • the silica particles of said mixture are typically of a size 15-30 nm.
  • the object of said mixture is the manufacture of transparent, organic based coatings that are wear and weather resistant.
  • the patent is limited in its scope to one organic system, namely acryl, which in its basis is a mixture of a monomer with silica particles, not an organic resin.
  • wear resistant coatings may be formed from a composition consisting of multifunctional organo-metallic components (designated A) that is combined with an organic monomer which includes several functional groups (designated B).
  • A multifunctional organo-metallic components
  • B organic monomer which includes several functional groups
  • From DE 199 24 644 is known a method for the manufacture of a lacquer comprising nano- particles.
  • the method comprises in-situ formation of the particles through hydrolysis and condensation of metal oxides, so-called sol-gel synthesis.
  • the objective with performing the manufacture in-situ as suggested, is to control the particle size so that agglomeration does not lead to larger particles than desired.
  • This publication too concentrates on systems leading to a single, common network of matrix and nano-particles, cfr. e.g. column 2, line 63-66.
  • aqueous paintings and lacquers are dispersions of the relevant polymer, which after removal of the solvent (actually dispersion agent) builds a protective layer. This means that the polymer is not present in the form of an actual solution. When the water evaporates and the polymer settles on a surface, the many minor polymer particles "float together" and builds a continuous, protective coating. Even if this takes place in a degree that is good enough for many purposes, aqueous paintings and lacquers still provide a lot weaker protection than organic based lacquers and solvents, where the polymer prior to application is completely dissolved, and during the hardening builds a continuous protective layer with a basis in the single molecules of the polymer.
  • the object of the present invention is to modify the wear resistivity of clear lacquer systems without changing other properties like brightness and glossiness.
  • the invention more precisely consists of a lacquer or a gel-coat of the kind mentioned initially, which is characterized by the features defined by the characterizing part of claim 1.

  • Preferred embodiments of the utilization according to the invention are defined by the claims 19-21.
  • the invention relates to substrate comprising a coating of the mentioned type.
  • the core of the invention may be expressed as providing the kind of lacquer or coating that the invention relates to with inorganic polymer particles of nano size, i.e. with a particle size mainly in the area 1-100 nm.
  • Such particles cannot just be “added” in the form of particles as such, their provision need to take place through one or more of the alternative methods by which the particles are formed through chemical reactions taking place in situ or immediately prior to their addition to the base component of the lacquer.
  • the three alternative embodiments of the method according to the invention, defined by the claims 9, 10 and 11 respectively, are in the following also designated as model 1, model 2 and model 3 respectively. It is however, also possible to combine the three methods as defined by claim 17.
  • particles of the relevant type and size are not present as discrete particles in a lacquer matrix.
  • the particles will rather form their own inorganic/ organic network that comes in addition to the organic network of the lacquer.
  • These two networks will be present side by side independent of each other, but they may to a larger or lesser degree be attached to each other through cross-linked bondings.
  • the degree of network formation is to some extent dependent also by which of the three manufacturing model that is chosen and by the particle size, and cannot be predicted entirely on a theoretical basis.

  • a solvent compatible with the solvent of the lacquer to be modified is used for this purpose.
  • the mentioned sol is added to the lacquer, and at this stage the sol includes nano-particles of desired size. It is preferred also to modify the surface of the particles through a treatment that may comprise adsorption of polymers, reactions with a silane, a zirconate, a zircoaluminate, an orthotitanate, an aluminate or a combination of such treatments.
  • a solution containing monomer compounds of the formula M(OR) n or R'-M(OR) n is used as a starting solution.
  • M is a metal ion and R is an organic group chosen among alkyl, alkenyl, aryl or combinations of these with from 1 to 8 carbon atoms.
  • R is a simple alkyl with 1-4 carbon atoms.
  • the index is an integer from 1 to 6 dependent upon the valency of the metal ion.
  • the first step is hydrolysis of the metal alkoxide, where alkoxide ligands are replaced by hydroxyl groups:
  • the second step is condensation, where hydroxyl groups either may react with hydroxyl or alkoxy groups from other metal centres, forming M-O-M bonds and either water or alcohol.
  • the resulting solution consists of inorganic polymer particles dispersed in a solvent.
  • a preferred variant includes the addition of a compound with functional OH-groups, like e.g. butyldiglycol or ethylhexanol during the hydrolysis/ condensation step. This has shown the formation of a stable sol that is compatible with lacquers/ gel-coats.

  • the hydrolysis provides for a polycrystalline precipitation or oxohydroxide precipitation taking place in contact with the components of the lacquer.
  • a suitable choice of inorganic compound combined with exchange (replacement) of alkoxide groups with strong ligands will slow down the hydrolysis reactions compared to condensation reactions, which will ensure that said chains do not become too long, but swill stay within a range herein denoted as oligomers.
  • model 1 it is preferred additionally to modify the surface of the particles through a treatment that may comprise adsorption of polymer, reaction with a silane, a zirconate, a zircoalummate, an orthotitane, an aluminate, or a combination of such treatments.
