Definitions

  • a method for making expanded paper honeycomb core material moisture- or waterproof, and the thus obtained honeycomb core material is provided.
  • the invention relates to a method for making expanded paper honeycomb core material moisture- or waterproof, as well as the honeycomb core material obtained by using this method.
  • Paper honeycomb core material is often used as a stiff and light construction material. In a number of applications it is necessary for the paper honeycomb core material to be moisture- or waterproof, as for example in construction panels for outside use, for use in transport and for use in floors and such like. In these cases, the honeycomb core material is usually delivered in moisture- and waterproof condition, after which the user himself provides one or both sides of the honeycomb core material with a cover layer of plastic or metal, for example.
  • Paper honeycomb core material is obtained by glueing a number of strips of paper onto each other at certain places, and, after the glue has dried, expanding this parcel of paper by pulling the outer strips of paper apart laterally, thus obtaining the hexagonal cellular struc ⁇ ture. After the expanded shape has been stabilized, the honeycomb core material is cut into slices of the desired thickness, which are further used as honeycomb core in honeycomb panels, for example.
  • Impregnation is effected by immersing the ex- panded honeycomb core material in a solution of formal- dehyde and water.
  • immersion usually takes place a number of times in order to apply the desired amount of resin.
  • the impregnated honeycomb core material must be dried with the aid of a drying facility in order to remove the surplus of water from the honeycomb core material.
  • this aim is achieved by the measure that the honeycomb core material is provided with a coating after expansion.
  • the paper honeycomb core material is provided with a sealing layer that offers an effective protection against moisture and water.
  • the coating can be applied in one layer, so that repeated immersions are not necessary. Nor does formaldehyde have to be used any more.
  • a coating-paper-coating-sandwich is obtained, which produces a lighter and stronger construction as compared to impregnated paper.
  • This method is cheaper than the one in which strips of paper are provided with a coating before they are glued to one another and expanded, as less coating material is needed, that is not on the glued areas, and as the usual glues may be used.
  • expenses are saved because spoilage of honeycomb core material during production has not yet been provided with the cost price raising coating.
  • the coating is preferably applied as a powder of a polymer material, as, in this way, it is possible to apply a coating of essentially equal thickness across the entire length of the honeycomb cells within a short time.
  • powder is applied by providing the paper honeycomb core material and the powder with an opposed electric charge, as a result of which a predetermined amount of powder can be applied to the honeycomb core material simply and quickly, by al- lowing the honeycomb core material to attract the powder electrically.
  • Moistening is preferably carried out by sprinkling with water, preferably such an amount of water being used, that a degree of humidity equal to 15-30 percentage by weight of the honeycomb paper is obtained.
  • water preferably such an amount of water being used
  • thermosetting polyester or epoxy is preferably used, since a strong moisture- and waterproof coating can be made from a thermosetting polyester or epoxy or a mixture of the two.
  • the honeycomb core material is heated after the thermosetting powder has been applied, in order to let the powder turn into a hard and thick coating and to stabilize the coated honeycomb core material in the expanded state, in which the heating is preferably carried out by means of hot air or by infrared radiation in order to obtain quick and even heating.
  • the invention also relates to the paper honeycomb core material that is obtained with the method described above.
