Definitions

  • the invention relates to a method for producing foils, in particular decorative foils, for coating hardboard, chipboard or wood panels by impregnating an absorbent base paper containing a filler such as titanium dioxide, kaolin, barium sulfate or the like with an impregnating agent, in particular a resin, and then drying.
  • a filler such as titanium dioxide, kaolin, barium sulfate or the like
  • an impregnating agent in particular a resin
  • Another disadvantage of the known method is that the papermaker can only economically produce batches of several tons. This means that the impregnator, who wants to produce a film with a certain color, has to take the raw paper of an entire batch from the papermaker even if the batch yields significantly more m 2 than it needs. For this reason, large stocks of raw paper with various colors have accumulated in practice at the film manufacturers.
  • the invention has for its object to provide a method for producing a film of the type mentioned, with which the film can be produced in terms of filler content and color more variable and in terms of costs cheaper than the known method described.
  • This object is achieved in a method of the type mentioned in that only a part of the filler required for sufficient opacity of the film is added to the stock in papermaking and the remaining part of the filler in the form of a flowable or pasty mass on the raw paper is applied before its impregnation.
  • the rest of the filler is preferably applied by direct or indirect gravure printing. It has proven to be beneficial if at most half of the total amount of filler is added to the whole fabric. Good results were achieved with a ratio of the two parts of 1: 2.
  • the paper maker supplies a base paper, the production of which is problem-free for the paper maker because of the low filler content.
  • the introduction of the remaining amount of filler up to a total filler content of over 40% is also not critical for the impregnator, although various application methods, in particular the gravure method, have proven successful for the application.
  • the same opacity can be used with a thinner film and thus with a lower m 2 paper weight that determines the price.
  • Less impregnating agent is also required because of the smaller paper volume.
  • the raw paper is conveyed as a material web by means of transport and guide means through an impregnation station, in particular as an immersion bath, and then through a continuous dryer, in particular as a floating dryer, the impregnation station in the conveying direction of the material web being an application unit for the flowable or pasty Filler mass is arranged.
  • a dryer acting on the web with the moist filler mass should preferably be arranged between the application unit and the impregnation station. With the coolant arranged between the dryer and the impregnation station, in particular the cooling roller, it can be prevented that the impregnation agent is heated over time by the web of material heated during the drying process.
  • Base paper with a filler content of 10 to 20% of the dry base paper is fed as a web 1 to an order unit 2.
  • the application unit 2 applies the remaining part of the amount of filler finally desired in the film to one side of the absorbent base paper.
  • the application unit 2 consists of a basin 3 filled with the flowable or pasty filler, an anilox roller 4 immersed in the filler, a doctor blade 5 and a counter-pressure roller 6, which is partially wrapped around by the web 1.
  • the application unit 2 works according to the gravure printing process with the oscillating doctor blade 5 and the anilox roller 4, preferably in the opposite direction.
  • the web 1 carrying the moist filler mass then arrives at an intermediate dryer 7, e.g. B. an infrared radiation dryer or a hot air dryer.
  • the web then runs over a cooling roller 8.
  • the cooling roller guides it with the back over a dampening roller 9 of the impregnation unit 10.
  • the dampening roller 9 is immersed in the impregnating agent located in a basin 11.
  • the fabric web is then passed into the bath of the impregnating agent and soaked over a spreader roller 12 and further deflection rollers.
  • the web so impregnated with impregnating agent then passes between two metering rollers 13, 14, the nip of which squeezes out unnecessary impregnating agent.
  • a conventional continuous dryer designed as a floating dryer is arranged behind the metering rollers 13, 1'4.
  • FIG. 2 differs from that of FIG. 1 only in that a second, similar application unit 15 with an intermediate dryer 16 and. a cooling roller 17 is provided in order to be able to apply the filler mass to both sides of the base paper.
  • the line in the application unit (s) is 2 to 5, in particular 10 g / m 2 .
  • the known method was generally based on a base paper with a weight of 80 g / m 2 .
  • a film produced by the process according to the invention has the same properties, in which the weight of the base paper is 40 to 60 g / m 2 . This results in lower costs per square meter for films produced according to the invention.
  • Another cost advantage for the method according to the invention results from lower storage costs, because it is possible for the impregnator to tint the base paper from one batch differently in order to be able to meet the different color requirements even with smaller areas.
