Description

Water-fast ceiling tile
Technical field
The present invention relates to the improvement of building panel, relate to especially the ceiling tile that is made by water slurry body or water base paste.
Background technology
Building panel, particularly permeable ceiling tile has the trend that becomes and tarnish when being exposed to water.A kind of mechanism that water droplet is contacted with ceiling tile that occurs is to be present in pipeline in the space of ceiling top and the condensation on pipe-line system.Condensate can drop in the back side of ceiling tile, and migrates to the visible appearance side of ceramic tile.Because water can obtain pollutant from the surface of its contact, and usually because ceiling tile is passed through in the water droplet migration, leach tannin from reclaiming newsprint or other plant base cellulosic material, and leach coloring agent from other components (it takes coloring agent to the front surface of ceramic tile) that are used for the ceramic tile composition, therefore may stain.
As the characteristic feature of most products, cost is crucial, and needs a kind of solution of economy to make water stain on the appearance side of building panel, particularly permeable ceiling tile reach minimum.
Summary of the invention
The invention provides a kind of solution of the water stain economy to the building panel visible face place that causes by panel due to water migration.More specifically, the present invention relates to following realization: be positioned at the barrier of the water droplet at back side of panel place by the generation section of playing a game, thereby water droplet can be evaporated before by panel its liquid contents is transportable.
Finding, is the good medium of realizing purpose of the present invention for the commercially available material of water-resistance being given fabric.Finding effective enforcement in limited coverage of the present invention, this material extensively can get, and is nontoxic and relatively cheap.By with the back side of hydrate (water carrier) simple application to rigid pad (ceramic tile is made by described rigid pad), thereby can make preferred waterproofing materials be equipped with this hydrate.Few covering of waterproofing work and simplicity low-cost and that use make it be suitable for the even more inexpensive production line of panel manufacturers.
Preferably make core pad (core mat) or ceramic tile stand high temperature, with quick force drying before can being absorbed by the core pad at carrier water or curing waterproofing materials.Preferably, described dry run can with the viewable side that is used for dry ceramic tile or panel on finish coat or the conventional process step of paint carry out simultaneously.
Description of drawings
Fig. 1 is for embodying the diagram isometric view of ceiling tile of the present invention; And
Fig. 2 is for using the schematic diagram of process of the present invention.
The specific embodiment
The present invention is applicable to can be used for covering the various building panels of wall or ceiling.A kind of suitable form of building panel is ceiling tile or panel used in suspended ceiling.Other forms of building panel comprise gypsum base walltile and wallboard.By the water slurry body or paste makes and the present invention is especially benefited from without the ceiling tile of impermeable layer or waterproof sheet material in the back side.In describing the manufacturing that embodies ceiling tile of the present invention, with reference to Fig. 1 and 2 of accompanying drawing.Rectangle ceiling tile 10 is suitable as the inset type panel in rectangular mesh in the suspended ceiling system of known construction.Ceramic tile has approximately 1/2 usually " to approximately 7/8 " between thickness and the nominal plane size of 2 ' x2 ', 2 ' x4 ' and 2-1/2 ' x5 ' or the metric equivalent of these panel size.Suspended ceiling panel or ceramic tile are made by water felt process or the water base preparation of casting of pasty state usually.When panel 10 was derived from water felt process, typical general preparation can comprise (by weight):
65% perlite filler
18% paper fiber
7% unmodified starch adesive, and
10% mineral wool fibres.
But the marked change of mineral wool content, such as until approximately 25%, and in this case, perlite can correspondingly reduce.Except the paper fiber, can use other cellulose source, as wood materials or xylophyta material.When suitable mixed being incorporated in when sprawling on sieve in the water slurry body of these compositions in the situation of water felt product, perhaps when similar composition is sprawled in dish in the situation of casting ceramic tile, these compositions are dehydrated and/or be dried to rigidity sheet material.Afterwards, the appearance side of sheet material or ceramic tile preform or front side are coated with surface coating or paint, and described surface coating or paint are generally the water material with some latex or other binder components.In the situation of water felt pad or core, if necessary, before with finish coat or top coat coating, but the facing side of grinding pad is to produce flat surfaces.In addition, before using finish coat, priming paint can be applied to the face side of pad, described priming paint can be for example clay-based.The ceramic tile 10 of Fig. 1 is installed orientation with it and is shown, and is included in surface coating 11, priming paint 12, water felt pad or core 13 on its lower visible surface and the following discussion of waterproof coating 14(on its back side or upper surface).
As described, the surface coating 11 on the facing side of ceramic tile 10 is generally water-based coating, and it has the Chinese white color so that high light reflectivity to be provided.Find, by with commercially available fabric waterproof material coated mat 13, this material can be used for successfully making ceramic tile 10 back side waterproof.Find unexpectedly, only need this material relatively in a small amount to realize gratifying result.An example that is applicable to implement product of the present invention is fluorocarbon polymer emulsion, as large aurification (the Daikin Chemical Europe GmbH of European Company by Dusseldorf ,Germany, Dusseldorf, Germany) the fluorocarbon polymer emulsion sold with trade mark TG-5601.This product is aqueous emulsion, and its available water is greatly diluted and remained valid simultaneously, even when the rate of application inaccuracy.The result of diluting initial emulsion be approximately 1/5 to 1/4 g/ft anti-water solid extremely slightly the coating.Although have the solid of such low concentration, find to have realized unexpected waterproof and water-fast degree.Under disclosed solid coverage scale, the water droplet beading on coating 14 and final evaporation.
Fig. 2 shows an example implementing process of the present invention.The dry pad with solid content as above or the dry sheet material 13 that make by conventional water felt process deliver on conveyer 20 to spray booth 21, and 21 places use water base top coat or paint 11 at spray booth.In this process, top coat or surface coating 11 facing up, but when ceramic tile was installed in ceiling, top coat faced down.Pad 13 is sent to dryer 22 by roller conveyors 23 from described spray booth.Sprinkler 24 with a plurality of spray nozzles is extending between a pair of cylinder at conveyer 23 on the whole width of conveyer.The waterproof liquid 14 of the sprinkler 24 above-mentioned dilutions of use sprays the downside of pad 13.Pad 13 by 14 coatings of top coat 11 and waterproofing materials is transmitted by dryer 22 by conveyer 26, and at dryer 22 places, these coating preferences are as dry and/or solidify the approximately duration of 45 seconds simultaneously at the temperature of about 220 ° of C.Can expect the additive method of using top coat and waterproofing materials.For example, can use roller coat or overflow.
From the space of suspended ceiling top or the pipeline in chamber and the conduit water condensate of the dripping back side that to fall the prior art ceiling tile, finally cause the variable color on face side or appearance side.Described variable color or the mechanism that stains are attributable to the condensed water infiltration and pass through ceramic tile.Condensate can be by the surface contamination of its process before arriving ceramic tile.In addition, when the ceramic tile body was passed through in the water infiltration, it may leach dyeing and produce material, as was present in the tannin in paper fiber or cellulose fibre.But contaminated water seepage stains surface coating thus by surface coating.Due to wish ceiling tile be porous demonstrating good sound absorption characteristics, therefore have the place, water source, do not adopting in situation of the present invention, it is common that water passes ceramic tile.Except the required porosity of typical ceiling tile, ceiling tile also has its initial water base characteristic, and described water base characteristic itself makes the ceiling tile porous.
Be apparent that, the disclosure is mode for example, and knowing under scope of the instruction that can comprise in not departing from the disclosure carried out various changes by increase, modification or removal details.Therefore, except be confined to following claims must the restriction degree, the invention is not restricted to specific detail of the present disclosure.
