Definitions

  • the invention relates to a method for the surface modification of release paper by adding organic silicon as a primer coat in papermaking.
  • silicone polymers have excellent release properties against sticky substances, e.g. Have pressure sensitive adhesives. These silicone polymers are e.g. in amounts of 0.3 g / m to 3 g / m (calculated), usually only in amounts of 0.5 g / m to 1.0 g / m, applied to the coating base paper as a backing material to give the paper adhesive properties . Approx. 50% highly satinised kraft paper is used as coating base paper, but also a large number of other papers ("Das Textil" (1985), No. 10 A, p. V 92 - V 96).
  • the silicone polymers applied to the carrier paper as a thin film can - solvent silicones, - dispersion silicones (aqueous emulsions or - Be solvent-free silicones, the polymerization of which - warmth, - UV radiation or - electron radiation can be done.
  • thermal displacement systems are still used today.
  • release papers are mainly coated with addition-crosslinking silicone systems, whereby chain-like polymers with vinyl end groups are crosslinked by reaction with hydrogen siloxanes under the influence of temperature and in the presence of predominantly platinum catalysts (see “Adhesion” (1973), No. 7).
  • Usual processing temperatures for convection drying are therefore approx. 180 ° C for silicone systems containing solvents, approx. 120 ° C to 150 ° C for aqueous silicone systems (emulsions) and approx. 150 ° C for solvent-free silicone systems.
  • the curing speed is between 2 and 25 seconds
  • the polyaddition can also be disrupted by small amounts of inhibiting constituents in the paper. These so-called “catalyst poisons” can delay or in extreme cases prevent the crosslinking reaction (see “Allgemeine Textilrundschau” (1986), No. 14, pp. 367-368). Likewise, the length of time the silicone systems are stored before using them increases the crosslinking time. In the case of extremely smooth paper surfaces, unfavorable interfacial tensions between paper and silicone systems can also lead to flow disturbances and adhesion problems (see “Paper and plastics processor” (1972), No. 17, p. 30).
  • the release paper is coated with the various silicone polymers on separate systems. This can be explained above all by the high demands on the surface quality of the carrier material before the silicone coating, in particular low micro-roughness, high solvent tightness and uniform thickness in the longitudinal and transverse directions of the paper web. Therefore the Most of all raw papers smoothed in a separate super calender. This is the only way to later apply a uniform silicone film with a high abhesive effect to the backing paper with relatively small amounts of coating. So far it has not been possible to siliconize abhesive papers for the technical sector with a defined and reproducible release force level within the paper machine. On-line siliconization is only carried out if the abhesive effect is low, for example with baking release papers and sack papers with hydrophobic properties.
  • the dried paper web inside the paper machine is used by means of conventional application devices, such as size press, blade or the like. coated with silicone resins.
  • aqueous silicone systems emulsions
  • various film formers and thickeners e.g. starch, alginates, caboxymethyl cellulose (CMC) or polyvinyl alcohol (PVA) can be added in small proportions according to the technical information sheets of the silicone manufacturers.
  • the silicone resin used always forms the main component , since it primarily affects the abhesive effect of the coated paper
  • Certain adhesive tapes for example carpet adhesive tapes, have lower requirements for the abhesive effect.
  • Methods are also known in which a surface application takes place during paper production with the aim of significantly improving the water resistance, wet strength or hydrophobization of the paper web and / or reducing the tendency of silicone resins to penetrate during a later (separate) coating.
  • Common silicone emulsions such as CMC, PCA and calcium stearates are added (SU 1320315 A1) or silicone emulsions of a defined composition (DE 2 326 828), possibly with the addition of additional film formers ("Paper” (1980), No. 11, pp. 36-37) used.
  • the raw paper pretreated in this way is partly satinized. The subject of these patents is always the achievement of more or less strong adhesive properties of the (on-line) coated base papers.
  • the object of the present invention is preferably to produce a release paper with modified surface properties within the paper machine, which has better adhesion and faster crosslinking at a lower temperature subsequent separate coatings with customary different silicone systems allowed. This also enables faster crosslinking at a lower temperature than previously an increase in the previously usual coating speed. Another advantage is the easier use of stored silicone systems, the reactivity of which is already more or less impaired.
  • the release paper can be made machine-smooth or subjected to subsequent smoothing, for example in a supercalender, before it is siliconized in a separate coating system.
  • the ideal possibility should thus be opened to coat even surfaces of low micro-roughness in an economically advantageous manner with minimal silicone applications without flow problems and adhesion difficulties.
  • Silicon savings through thinner coatings while securing the desired (usually low) release forces were previously only possible with the use of plastic films, which in turn had the disadvantage of a lower one have thermal resistance.
  • Another advantage of the desired surface modification of release paper should be the extensive suppression of the negative influence of inhibiting paper components (catalyst poisons) on silicone crosslinking.
  • the desired surface modification of release papers by means of silicone additives has a completely different chemical structure and properties than the above-mentioned aqueous silicone systems (emulsions) to the usual impregnation or surface solution, which is applied in the paper machine to the almost dry paper web with a solid moisture content of 2 to 12% with conventional application devices be applied.
  • roller and doctor blade applicators or dip impregnation devices are known as customary application devices for the surface finishing of release paper.
  • the silicone additives are silicone compounds from the two main groups A organosilanes and B organo polysiloxanes represents.
  • the main group B organopolysiloxanes have at least 3 silicon-bonded hydrogen atoms per molecule and are, for example, copolymers of: Dimethylhydrogensiloxane, methylhydrogensiloxane, dimethylsiloxane and trimethylsiloxane units, copolymers of trimethylsiloxane units, methylhydrogensiloxane units and hydrogensiloxan-, copolymers of trimethylsiloxane, dimethylsiloxane and Methyhydrogensiloxanäen, copolymers of Methyhydrogensiloxan- and trimethylsiloxane units, copolymers of methylhydrogensiloxane, diphenylsiloxane and trimethylsiloxane units, copolymers of methylhydrogensiloxane -, dimethylhydrosiloxane and diphenylsiloxane units, copolymers of methylhydrogensiloxane,
  • organopolysiloxanes are preferably not removed by hydrogen and siloxane oxygen atoms saturated silicon valences saturated by methyl residues. Processes for the preparation of organopolysiloxanes of this type are generally known.
  • organopolysiloxanes used for the purposes of the invention are emulsified in water. All known procedures and dispersants for the emulsification of organopolysiloxanes in water can be used.
  • organ silanes assigned to main group A include both organofunctional alkoxysilanes and alkyl alkoxysilanes.
  • organofunctional silanes include: 3-glycidyloxypropyl-trimethoxyxilane, N-aminoethyl-3-aminopropyl-trimethoxysilane, 3-aminopropyl-triethoxysilane, 3-aminopropyl-methyldiethoxysilane, 3-aminopropyl-trimethoxysilane, 3-amino-propyl-tris (2-methoxy) ethoxy silane, 3-methacryloxypropyl-trimethoxysilane, 3-mercaptopropyl-triethoxylsilane, 3-mercaptopropyl-trimethoxysilane, 3 mercaptopropylmethyl-dimethoxysilane, 3-chloropropyl-triethoxsilane
  • organosilanes have the ability to react with an inorganic substrate as well as with organic polymers to form solid bonds. This is due to the structure of the silane molecule, which has alkoxy groups that can react with the active sites of the inorganic material after hydrolysis.
  • silanes have a functional group that is firmly attached to the silicon atom via a carbon chain. This group can undergo chemical reactions with suitable resins.
  • the silicone compounds mentioned can be used alone or in combination with conventional impregnation or surface glue compositions for release base papers, which mostly differ from the film formers alginate, starch, CMC, PVA or other polymer solutions and polymer dispersions (latexes) Licher chemical structure exist, are added proportionately.
  • silicone compounds are only added in proportions of up to 15% (calculated) of the usual surface preparation in order to avoid any undesirable side effects, e.g. adhesive properties to give the paper.
  • these silicone additives represent an additional cost factor.
