Definitions

  • the present invention relates to a method for manufacturing a coated timber or timber-based panel. It also relates to a timber or timber-based panel coated by using such a method.
  • Timber panels such as particleboard, chipboard, plywood, oriented strand board, medium density and high-density fibre boards are used in many applications. When the panels are used outdoors, such as, for example, for temporary hoardings around a construction site, it may be desirable to apply a protective or decorative coating. This is generally achieved by painting the wood in-situ.
  • a method for manufacturing a coated timber or timber-based panel by applying a protective coating comprising acrylic binders and particulate fillers comprising conveying the panel through a spraying booth in a first direction, reciprocating automated spraying apparatus in said spraying booth in a second direction transverse to the first direction so as to apply the coating to a surface of the panel, conveying the coated panel through a drying oven, and then conveying the dried panel through a cooling chamber.
  • the panel may be dried in the drying oven by at least one infra-red emitter.
  • the infra-red emitter may be operated at a power density in the range 30 to 50kW/m 2 , or more preferably substantially 40kW/m 2 .
  • the panel may pass through the drying oven within 25 to 30 seconds.
  • the panel may be cooled in the cooling chamber by air being directed towards it as it is conveyed through the chamber.
  • the panel may pass through the cooling chamber within 25 to 30 seconds.
  • the panel may be oriented strand board or any other suitable timber-based material.
  • the spraying apparatus may be supported on an overhead carriage movable along a track and the track may extend in a direction that is substantially perpendicular to the direction of movement of the panel through the spraying booth.
  • the coating may be supplied to the spraying apparatus by means of a peristaltic pump.
  • Edges of the panel are preferably first painted with the coating before it is conveyed through the spraying booth.
  • a production line for coating a timber panel with a protective, weatherproof layer comprises, in sequence, an in-feed conveyor 10, a spraying booth 11, a drying oven 12, a cooling chamber 13, a gantry 14, an out-feed conveyor 15 and an off-load station 16.
  • the timber panel (depicted in dotted line in some of the figures and given the reference P) may be manufactured from any suitable form of wood or wood-based material such as, for example, particleboard, chipboard, plywood, oriented strand board, medium density and high-density fibre boards. It has two opposed major surfaces and four side edges.
  • the coating is an acrylic-based paint comprising pure acrylic binders, crushed and precisely graded mineral fillers such as calcium carbonate and/or dolomite or silica sand, additives, such as a plasticizer, that afford the paint elastomeric properties and durability, and solvent.
  • the coating has a solids content in the range 67 to 75% by volume depending on the application.
  • the paint may have a range of different texture grades and colours.
  • Coalescent solvents are removed to provide for a coating that has a low volatile organic component rating.
  • the timber panel Before the timber panel is supplied to the production line it is pre-treated by sanding the major surfaces to be coated with, for example, a belt sanding machine. This provides multiple microscopic channels or undulations in the surfaces that allow the paint coating to key into the panel. The panel is then cleaned with brushes and dust-extraction equipment to remove all dust particles, salts, oils, grease etc so as to ensure the paint will bond to the surfaces.
  • edges of the panel may then be coated with the paint by means of manual application with brushes or with spray guns.
  • the panels are then stacked in a storage area 17 adjacent to the in-feed conveyor 10 and are manually loaded singly on to the in-feed conveyor in the direction of arrow A.
  • the in-feed conveyor 10 delivers the panels to a conveyor belt 18 in the spraying booth 11.
  • the spray booth 11 comprises an enclosure 11a through which the panels pass on the conveyor belt 18 under an automated spraying device 20 by which it is spray painted with the coating.
  • the automated spraying device 20 comprises a pair of spray guns 21 supported over the conveyor belt 18 in a carriage 22.
  • the carriage 22 is driven along an overhead track 23 by a transport mechanism 24 such that it reciprocates back and forth in a direction (see arrows B in figures 2 and 3 ) transverse to the direction of movement of the conveyor 18.
  • the spraying device 22 is depicted in figure 3 in two locations at the ends of its length of travel in each direction.
  • the speed of reciprocation of the carriage 22 is synchronised carefully with the speed of the conveyor 18 so as to ensure a uniform application of the coating to the panel surface.
  • the spray guns 21 are supplied with the coating paint from a reservoir or bulk container 25 via a peristaltic pump 26 and tubing 27 to a common manifold (not shown) from where the paint proceeds to a nozzle 29 of each gun 21.
  • the nozzles are disposed at a height of approximately x cm above the surface of the panel.
  • a spray gun 21 is shown in more detail in figure 6 in the context of the bulk container 25 via the pump 26 and tubing 27.
  • the gun 21 has an inlet end 30, an outlet tube 31 adjacent to the nozzle 29 and an intermediate ball valve 32 that is manually operable to open and close the valve by means of a handle 33.
  • Air is supplied to the nozzle 29 in order that the coating leaves the nozzle in a spray. It is supplied under pressure from a source 34 of compressed air via a conduit 35 to a side port 36 immediately preceding the nozzle 29.
  • the conduit 35 is closable by means of a manually operable ball valve 37.
  • the coated panel passes on the conveyor 18 to a drying oven 12 where the panel P is continuously transported under an array of medium wave infra-red emitters 30.
  • the conveyor 18 is disposed relative to the oven 12 such that the panels pass under the emitters 30 at a distance of around 100mm.
  • the emitters 30 are designed to provide an output in the range 0 to 63 kW/m 2 . In tests it was established that a preferred range was 30-50 kW/m 2 and more preferably 40kW/m 2 .
  • the rate of progress of the conveyor 18 is such that the panels are cured by the emitters for a period of around 25 to 30 seconds.
  • the cured panels P are then transported by the conveyor 18 through a cooling chamber 13 so as to cool coating and the panels P and to accelerate the hardening of the coating. This reduces the risk of damage to the coating by way of flattening or indentation and also reduces the tendency of the coating to adhere to the surface of an adjacent panel when stored after removal from the production line.
  • air at ambient temperature is blown through ducts 31 such that it egresses on to the upper surface of the panel P.
  • the temperature of the surface coating is thus cooled from around 90°C to approximately 40°C.
  • the panels are resident in the cooling chamber for around 25 to 30 seconds.
  • the panels are conveyed to a gantry 14 before passing to the out-feed conveyor 15 that transports the coated panels to the off-load station 16 where the panels P are removed from the production line and stacked on to pallets for storage and/or transportation.
  • the operation of the various components of the production line is controlled by a PLC or similar.
  • the production line is operable to process panels at a speed of greater than 120 panels per hour.
  • the edge sealing of the panels is important to prevent ingress of moisture at those edges.
  • the paint is such that it can be touched up easily by manual application if damaged.
  • the panels are suitable for use in the construction or DIY industry for many applications including, for example, walling, hoardings or roofing.
  • the coating has high bond strength and provides a durable surface layer for protection against the weather including upper and lower extremes of climactic temperature.
  • the elastomeric nature of the coating enables it to cover defects and minor cracks.
  • the coating can be made available in different textures (using different filler grades, additives and/or nip coating rollers between the spraying booth and the dying oven) and different colours (by adding pigments) for decorative application.
