Definitions

  • the invention relates to a tray device with at least one flat surface formed by an anti-slip covering, the anti-slip covering being formed by a coating made of an aliphatic polyurethane.
  • the invention relates to a method for applying an anti-slip covering to a flat surface.
  • the layers in question can be formed from various suitable materials which bring about such a high surface friction of the objects deposited on these layers that the frictional resistance is greater than an acceleration caused by the earth's gravity when the tray is in a normal inclined position.
  • the known anti-slip coverings consist either of a film arranged above the surface of a tablet device, or of a substance applied to the surface, which is applied to the surface in liquid form and is formed into a layer in a subsequent curing process, which is solid with the surface connected is.
  • the known anti-slip coverings have various disadvantages. In the event that they are formed from a film, there is usually a lack of permanent adhesion to the tablet surface, and in the event that they are formed from a hardened liquid substance, there is a lack of sufficient homogeneity of their thickness and thus both in the visual aesthetics of its surface as well as in a homogeneous anti-slip effect.
  • the invention is therefore based on the object to provide a tray device in which the Anti-slip layer is firmly connected to the surface of the tray and is particularly homogeneous.
  • the invention is based on the object of specifying a method by means of which a tray device with a fixed, non-slip layer of homogeneous thickness can be provided.
  • this object is achieved in that the coating is applied to the surface using the screen printing method.
  • the coating is formed from an aliphatic polyurethane. This creates a particularly effective anti-slip effect.
  • the printing screen used for screen printing is a metal screen.
  • the metal screen preferably has about 80 metal threads per square centimeter. In practice, this value has given good results with regard to the quality of the anti-slip layer.
  • the diameter of a metal thread is preferably dimensioned at approximately 0.10 millimeters, and the mesh size of the metal threads is preferably dimensioned at approximately 224 micrometers.
  • the threads of a metal sieve are made of steel.
  • the metal threads are particularly stable, durable and resilient in this version.
  • the non-printing areas of the printing screen are preferably formed by three layers of photoresist applied to the top of the printing screen and two below onto the printing screen, which are cured by means of a mixed-in sensitizer by means of a UV lamp.
  • the printing areas of the printing screen are covered with a black protective layer before the process of curing the at least one photo layer, the uncured photoresist then being rinsed away with water.
  • a sufficiently robust matrix for printing a suitable chemical substance in particular a hydroxyl-containing polyester mixed with an aliphatic isocyanate
  • the printing screen is preferably turned around a diagonal axis for a period of approx. 30 minutes after every 5 minutes. This measure has the effect that the photoresist forms a homogeneously thick, dense matrix.
  • the metal screen is generally preferably approximately 100 cm by 110 cm, a screen area of approximately 50% being used for printing on a surface. This dimensioning is intended for round tray devices which have a diameter of approximately 40 to 50 square centimeters.
  • the predecessor substrate of an aliphatic polyurethane is preferably a hydroxyl-containing polyester which cross-links with an aliphatic isocyanate during curing and forms an anti-slip coating which forms an aliphatic urethane after completion of a drying process.
  • the substrate is preferably applied directly to the surface to be printed without applying a primer layer.
  • a substance with such a composition has the advantage that it can be applied to a tray device with very satisfactory results by means of the method according to the invention and has very good anti-slip properties. The invention is explained below using a preferred embodiment.
  • a tablet device with a flat upper side has an anti-slip covering made of an aliphatic polyurethane attached to the surface of the upper side, the predecessor substrate of the aliphatic polyurethane being a two-component mixture consisting of a hydroxyl-containing polyester, to which an aliphatic isocyanate has been added for the purpose of curing, and this two-component mixture is applied to the surface by screen printing.

Abstract

L'invention concerne un procédé pour appliquer un revêtement antidérapant sur une surface plane. Selon ce procédé, une couche antidérapante présentant une épaisseur homogène est fixée sur un plateau. A cet effet, on applique par sérigraphie sur la surface plane au moins une couche d'un substrat de départ constitué d'un polyuréthanne aliphatique.
