Definitions

  • Water resistance is important to prevent delamination and substrate swelling. We have found that water resistance decreases in the order LOCRIL 3134 > URACRIL T > EBECRYL 1810 but is enhanced by heavier film weights and by inclusion of hydrophobic monomers e.g. HDDA, TMPTA. Water resistance is also improved by including a silicone diacrylate such as EB 350 (available from UCB) in the oligomer blend. In general, it is preferable to select those compositions which include oligomers having the highest crosslinking density and the greatest hydrophobicity e.g. urethane acrylates with alkyl backbones and with high functionality.
  • the coating formulation may be applied to the paper by any suitable means for example by use of a roller coater at elevated temperature, for example 45°C - 50°C, by knife coaters or by other means.
  • the applied coating is cured by an electron beam. Curing is typically conducted at speeds of 400 m/min. with a dose of 3 M rads in the presence of an inert (N_) atmosphere. Under these conditions (400 m/min) the dwell time of the composition between coating and curing is about 0.3 seconds. Cured coatings of 1 - 15 gsm give adequate opacity when paints of 40 - 70% pigment loading are used depending on choice of paper.
  • the cured coated sheet or foil so produced is sufficiently flexible to be wound onto a roll in long lengths at 400 m/min and may be economically produced and stored on the roll.
  • the cured coated sheet or foil is subsequently unwound from the roll and laminated onto a composite board, particularly hardboard, particle board or other substrate.
  • the laminating process varies slightly depending on the adhesive but is essentially application of adhesive to the substrate by roller coater followed by IR heating and application of the laminating foil to the substrate ia a modified roller coater set up to apply the - In ⁇ appropriate ' laminating pressure.
  • Typical temperatures after IR heating are 80°C and typical operating speeds are 30 m/minute.
  • Ease of application of adhesives is PVA>EVA>U-F (higher laminating temperatures are required in the same order) .
  • offcuts of hardboard or particle board may be glued together in a continuous edge-to-edge assembly and the coated paper may be laminated to the surface, the opacity of the paper being sufficient to mask the underlying joints.
  • the "coated and cured" paper does not have the hardness or abrasion resistance of a high pressure melamine resin lamination sheet but performs very well in comparison with prior art paints in respect of scuff resistance, abrasion resistance and resistance to common household solvents and water.
  • laminated board made according to the invention is inexpensive to manufacture in comparison with prior art laminates utilizing melamine sheets.
  • coated and cured paper as described herein is sufficiently flexible for handling in rolls, and thus is able to be laminated to a chip board substrate on a continuous basis and at comparatively low production costs.
  • the invention may be embodied in other forms and the coating compositions may be varied from those described to an extent which is determinable by routine experiment.
  • Modifiers such as gloss or matt additives, viscosity control agents, extenders, fillers and catalysts and the like may be added without departing from the invention herein disclosed.

Abstract

On fabrique un panneau composite présentant une surface décorative ou protectrice en enduisant une feuille de support d'une compostion pigmentée vulcanisable par faisceau d'électrons, en vulcanisant la composition par exposition à un faisceau d'électrons, puis en collant au panneau la feuille de support enduite ainsi vulcanisée. La feuille de support est de préférence constituée d'un papier choisi pour sa grande opacité. La composition d'enduction comprend de préférence des oligomères d'acrylate et un ou plusieurs monomères d'acrylate ayant une viscosité de préférence suppérieure à 1000 cps à une température de 20°C et appliqués de façon à avoir pour effet des poids d'enduction inférieurs à 15 gsm. Une composition d'enduction et un papier enduit sont également revendiqués.
