Definitions
- the invention relates to improvements in construction panels and, in particular, to ceiling tiles made from a water slurry or a water based paste.
- Construction panels particularly, water pervious ceiling tiles have a tendency to become stained when exposed to water.
- One mechanism that occurs to bring water droplets in contact with a ceiling tile is
- condensation on pipes and ductwork existing in the space above the ceiling can drip onto the backside of the ceiling tile and migrate to the visible appearance side of a tile. Staining can occur because the water can carry off contaminants from surfaces it contacts and, often, because the water droplets migrate through a ceiling tile and leach tannin from recycled newsprint or other plant based cellulose materials and staining agents from other components used in the tile composition bringing such staining agents to the front surface of the tile.
- construction panels particularly, water pervious ceiling tiles .
- the invention provides an economical solution to water staining at the visible face of
- the invention involves the realization that by creating a barrier to water droplets locally at the backside of a panel, the droplets can be caused to evaporate before their liquid content can migrate through a panel.
- Such material is widely available, non-toxic, and relatively inexpensive in the limited coverage found to be effective in practicing the invention.
- the preferred waterproof material can be applied with a water carrier by a simple application of the same to the backside of a rigid mat from which the tile is fabricated.
- the very light coverage and consequent low cost of the waterproofing treatment and the simplicity of application makes it practical for use in even the less expensive product lines of a panel manufacturer.
- the core mat or tile is preferably subjected to an elevated temperature to quickly force dry or cure the waterproofing material before the carrier water can be absorbed through the core mat.
- this drying process can be done simultaneously with the conventional process step used to dry a finish coat or paint on the visible side of the tile or panel.
- FIG. 1 is a diagrammatic isometric view of a ceiling tile embodying the invention
- FIG. 2 is a schematic diagram of a process utilizing the invention. DESCRIPTION OF THE PREFERRED EMBODIMENT
- the invention is applicable to various construction panels that can be used to cover walls or ceilings.
- One suitable form of a construction panel is a ceiling tile or panel used in suspended ceilings.
- Other forms of construction panels include gypsum based wall tiles and wallboard. Ceiling tiles made from a water slurry or paste and not backed with a water impervious film or sheet are especially benefited by the present invention.
- a ceiling tile made from a water slurry or paste and not backed with a water impervious film or sheet are especially benefited by the present invention.
- FIGS. 1 and 2 of the drawing A rectangular ceiling tile 10 is adapted to be used as a lay-in panel in a rectangular grid in a suspended ceiling system of generally known
- the tile typically, will have a thickness of between about 1/2" to about 7/8" and nominal planar dimensions of 2 ' x 2', 2 ' x 4', and 2-1/2' x 5' or metric equivalents of these panel sizes.
- Suspended ceiling panels or tiles are typically made from a water felting process or a paste like water based castable formulation. Where the panel 10 is derived from a water felting process, a typical approximate formulation, on a weight basis, can comprise:
- the mineral wool content can vary
- the perlite can be reduced accordingly.
- paper fiber other cellulose sources can be used such as wood or woody plant materials.
- the appearance or front side of the board or tile preform is coated with an appearance coating or paint usually a water based material having some latex or other binder component.
- the finish side of the mat if necessary, can be ground to create a flat surface prior to coating with a finish or top coating.
- a primer coat that may be clay based, for example, can be applied to the face side of the mat.
- the tile 10 of FIG. 1 is shown in its installed orientation and includes an appearance coating 11 on its lower, visible face, a primer coat 12, a water felted mat or core 13, and a waterproof coating 14, discussed below, on its back or upper face.
- the appearance coat 11 on the finish side of the tile 10, as mentioned, is typically a water based coating with a white pigment color to provide high light reflectivity. It has been discovered that
- fluorocarbon polymer emulsion such as that marketed by Daikin Chemical Europe GmbH, Dusseldorf,
- This product is a water based emulsion which can be greatly diluted with water while remaining effective even when the application rate is imprecise.
- the result of the dilution of the original emulsion is a very light coating of waterproofing solids of about 1/5 to 1/4 grams/sq. ft. Despite such a low
- FIG. 2 illustrates an example of a process for practicing the invention.
- a dried mat or board 13 made by a conventional water felting process with a solids content such as described above is carried on a conveyor 20 into a spray booth 21 where a water based top coat or paint 11 is applied.
- the top coat or appearance coat 11 faces up in this process but when the tile is installed in a
- the top coat faces down.
- the mat 13 is conveyed from the spray booth to a dryer 22 by a roller conveyor 23.
- a sprinkler 24 carrying a plurality of spray nozzles extends between a pair of rolls of the conveyor 23 across the width of the conveyor.
- the sprinkler 24 sprays the underside of the mat 13 with dilute waterproofing liquid 14 described above.
- the mat 13 coated with the top coat 11 and waterproof material 14 is conveyed by a conveyor 26 through the dryer 22 where these coatings are preferably simultaneously dried and/or cured for example, at a
- top coat and waterproofing material are contemplated.
- roll coating or flooding can be employed.
