Description
Den foreliggende oppfinnelse vedrører en med dampsperre utrustet byggplate eller et av byggplaten fremstilt byggelement, anvendelse av polyvlnylhalogenld som dampsperre, samt en metode til å unngå at vanndamp trenger inn 1 veggkonstruksjoner ved at det på den ene siden av veggkonstruksjonens Indre beklednlngsplate anbringes en hinne, som vesentlig hindrer vannet 1 å trenge gjennom. The present invention relates to a building board equipped with a vapor barrier or a building element produced from the building board, the use of polyvinyl halide as a vapor barrier, as well as a method to prevent water vapor from penetrating wall constructions by placing a membrane on one side of the wall construction's inner cladding board, which essentially prevents the water 1 from penetrating.
Det er fra tidligere kjent at man kan anbringe en polyetylenhlnne som fungerer som dampsperre mellom ytterveggens Indre beklednlngsplate og varmelsolerlngen. På denne måten kan man dog Ikke hindre at fuktighet flytter seg fra det varme og fuktige rommet til den Indre beklednlngsplaten. Dette problemet kunne naturligvis elimineres ved å feste en polyetylenhlnne til den siden av den indre beklednlgsplaten som vender mot det varme romet, men denne løsningen ville i sin tur føre til andre uoverstigelige problemer ettersom maling og tapetklister ikke fester på en slik polyetylen-flate, It is known from the past that you can place a polyethylene sheet which acts as a vapor barrier between the outer wall's inner cladding panel and the thermal insulation layer. In this way, however, it is not possible to prevent moisture from moving from the warm and humid room to the inner cladding panel. This problem could of course be eliminated by attaching a polyethylene sheet to the side of the inner cladding panel facing the warm room, but this solution would in turn lead to other insurmountable problems as paints and wallpaper pastes do not adhere to such a polyethylene surface,
I praksis er det å lime sammen polyetylenflater en arbeidskrevende og usikker prosess. Med de nåværende tape-kvaliteter vil skjøten ofte løsne og dampsperren vil ikke lenger være tett. Polyetylenhinnens festing til forskjellige konstruksjoner kan heller Ikke skjøtes tett med nåværende arbeidsmetoder. Polyetylenhinnen rives opp også i forbindelse med el-gjennomføringer og når det slås spiker eller festeanordninger i veggen. Polyetylenhinnen blir skjør når den eldes hvorved det ofte opptrer sprekkdannelser. Reparasjon av slike sprekkdannelser er i praksis ofte umulig ettersom polyetylenhinnen er gjemt bak den indre beklednlngsplaten. Hensikten med foreliggende oppfinnelse er å fjerne de ovennevnte ulemper og å frembringe en byggplate eller et av bypplatene tilvirket byggelement som har en sømløs hinne, som er vesentlig fukt-ugjennomtrengelig som dampsperre, hvor hinnen ikke blir skjør når den eldes, men tvert imot blir stadig tettere. In practice, gluing together polyethylene surfaces is a laborious and uncertain process. With the current tape qualities, the joint will often loosen and the vapor barrier will no longer be tight. The attachment of the polyethylene membrane to different constructions cannot be joined tightly with current working methods. The polyethylene membrane is also torn up in connection with electrical conduits and when nails or fasteners are driven into the wall. The polyethylene membrane becomes fragile when it ages, which often causes cracks to form. Repair of such crack formations is often impossible in practice as the polyethylene membrane is hidden behind the inner cladding panel. The purpose of the present invention is to remove the above-mentioned disadvantages and to produce a building panel or a building element made from the byp panels which has a seamless membrane, which is substantially impermeable to moisture as a vapor barrier, where the membrane does not become fragile when it ages, but on the contrary becomes constantly tighter.
Oppfinnelsens hovedsaklige kjennetegn fremgår av vedlagte patentkrav. The main characteristics of the invention appear from the attached patent claims.
Ifølge oppfinnelsen utbredes en fukt-ugjennomtrengelig hinne på den fuktige siden av byggelementet eller -platen, hvor hinnen er polyvlnylidenhalogenid, fortrinnsvis polyvinylidenklorid som inneholder et flytende sjikt. According to the invention, a moisture-impermeable membrane is spread on the moist side of the building element or panel, where the membrane is polyvinylidene halide, preferably polyvinylidene chloride, which contains a liquid layer.
Tykkelsen på flatebelegningslakken er hensiktsmessig The thickness of the surface coating varnish is appropriate
30-300 pm, f.eks. ca. 160 pm. Lakken kan også strykes på byggelementets eller -platens kanter, spesielt gjelder dette en stor plate. 30-300 pm, e.g. about. 160 p.m. The varnish can also be applied to the edges of the building element or slab, especially for a large slab.
Oppfinnelsen gjelder også anvendelse av polyvlnylidenhalogenid, fortrinnsvis en lakkdispersjon som inneholder polyvinylidenklorid, spesielt vanndispersjon, som byggelementets eller platens fuktighetssperre på den varme siden, og fortrinnsvis anvendes en slik vanndispersjon som inneholder 10-60 vekt-* polyvinylidenklorid pluss eventuelle The invention also relates to the use of polyvinylidene halide, preferably a lacquer dispersion containing polyvinylidene chloride, especially water dispersion, as the building element's or board's moisture barrier on the warm side, and preferably such a water dispersion is used which contains 10-60 weight* of polyvinylidene chloride plus any
hjelpematerialer og pigmenter. auxiliary materials and pigments.
Som hjelpematerial kan anvendes hjelpeoppløsningsmiddel, som f.eks. glykoleter, fortykningsmiddel som f.eks. polyuretan, fuktemiddel som f.eks. polyetylenoksyd, skumhemmer som f.eks. silikonolje, pH-reguleringsmiddel som f.eks. ammoniakk samt konserveringsmiddel som f.eks. 1,2-benzisotiazolin-3-on, og som pigment kan anvendes f.eks. talk. Som bindemiddel anvendes fortrinnsvis vanndispersjon av polyvinylidenklorid, som inneholder ca. 60 vekt-* polyvinylidenklorid. Auxiliary solvent can be used as an auxiliary material, such as e.g. glycol ether, thickener such as e.g. polyurethane, wetting agent such as e.g. polyethylene oxide, foam inhibitor such as e.g. silicone oil, pH regulator such as e.g. ammonia and preservatives such as 1,2-benzisothiazolin-3-one, and as a pigment can be used e.g. talk. Water dispersion of polyvinylidene chloride, which contains approx. 60 wt* polyvinylidene chloride.
Foreliggende oppfinnelse gjelder også en fremgangsmåte for å unngå at vanndamp trenger inn i veggkonstruksjonen ved at det på den siden av den indre beklednlngsplate, som vender mot det fuktige lokalet påføres polyvlnylidenhalogenid, fortrinnsvis et sjikt som inneholder polyvinylidenklorid. Fortrinnsvis påføres en vanndispersjon som inneholder 10-60 vekt-* polyvinylidenklorid pluss eventuelle hjelpestoffer og pigment. Fortrinnsvis påføres 100-500 g lakk pr. m<2 >byggelement eller -plate. The present invention also applies to a method for preventing water vapor from penetrating into the wall construction by applying polyvinylidene halide, preferably a layer containing polyvinylidene chloride, to the side of the inner cladding panel, which faces the damp room. Preferably, a water dispersion containing 10-60 weight-* of polyvinylidene chloride plus any auxiliary substances and pigment is applied. Preferably, 100-500 g of varnish is applied per m<2 >building element or plate.
Med en dispersjon som anvendes ifølge foreliggende oppfinnelse kan alle typer flater behandles, som f.eks. gips, styroks, plast, tre og spesielt byggplater. Dispersjonen som benyttes ifølge foreliggende oppfinnelse egner seg spesielt ved behandling av sponplater, idet den ikke bare hindrer vanndamp i å trenge fra det varme rommet inn i sponplaten, slik at det oppstår forandringer i sponplaten pga. fukt, men samtidig hindrer emisjon av formaldehyd fra sponplaten til boligrommet. Selv sponplatens kanter kan behandles med dispersjon ifølge oppfinnelsen, hvoretter ingen spesiell behandling av sponplatens kanter er nødvendig. With a dispersion used according to the present invention, all types of surfaces can be treated, such as e.g. plaster, styrox, plastic, wood and especially building boards. The dispersion used according to the present invention is particularly suitable for treating chipboard, as it not only prevents water vapor from penetrating from the warm room into the chipboard, so that changes occur in the chipboard due to moisture, but at the same time prevents the emission of formaldehyde from the chipboard into the living room. Even the edges of the chipboard can be treated with dispersion according to the invention, after which no special treatment of the edges of the chipboard is necessary.
Oppfinnelsen beskrives i det følgende nærmere ved hjelp av eksempler. The invention is described in more detail in the following by means of examples.
Eksempel 1 Example 1
Vanndampgjennomtrengeligheten for en overflatebehandlet og en ikke overflatebehandlet sponplate ble målt på følgende måte: 12 mm tykke sponplatestykker ble behandlet med den neden-stående dispersjonen ved å påstryke sponplatestykkenes ene side to ganger slik at hinnetykkelsen var ca. 160 pm. The water vapor permeability for a surface-treated and a non-surface-treated chipboard was measured as follows: 12 mm thick chipboard pieces were treated with the below dispersion by brushing one side of the chipboard pieces twice so that the film thickness was approx. 160 p.m.
De overflatebehandlede og ikke overflatebehandlede sponplatestykkene ble festet med den behandlede siden ut, som lokk på et kar, hvor det ble oppbevart tørr kalsiumklorld. Karet ble oppbevart ved en temperatur på 20°C, og en relativ fuktighet på 70*, og vanndampens bevegelse gjennom sponplatestykkene til karet ble undersøkt ved å veie prøvekarene med ca. en ukes mellomrom. The surface-treated and non-surface-treated chipboard pieces were attached with the treated side out, as a lid to a vessel, where dry calcium chloride was stored. The vessel was kept at a temperature of 20°C, and a relative humidity of 70*, and the movement of water vapor through the chipboard pieces of the vessel was examined by weighing the test vessels with approx. one week apart.
Trykkforskjellene for vanndampen på ytre og indre flate av prøvestykkene var lfcOO Pa. Flaten av de anvendte prøve-stykker hadde areal 78,5 cm2 , og prøvetiden var 28 døgn. The pressure differences for the water vapor on the outer and inner surfaces of the test pieces were lfcOO Pa. The surface of the test pieces used had an area of 78.5 cm2, and the test period was 28 days.
Ved måling av gjennomtrengelighet og motstand mot vanndamp ble det funnet at den gjennomsnittlige gjennomtrengeligheten for vanndamp for sponplaten som var behandlet ifølge oppfinnelsen, var 0,022 g/m<2> h (0,0037 x IO-<9> kg/m<2> s Pa), og vanndampens motstand 270 x IO-<9> m<2> s Pa/kg. For ubehandlet sponplate var den gjennomsnittlige gjennomtrengelighet for vanndamp 3,35 g/m<2> h (0,582 x 10~<9> kg/m<2> s Pa), og vanndampens motstand 1,7 x IO-<9> m<2> s Pa/kg. Gjennomtrengeligheten for vanndamp var således merkbart lavere for sponplater behandlet Ifølge oppfinnelsen enn for ubehandlede plater, og vanndampmotstanden var på tilsvarende måte høyere. When measuring permeability and resistance to water vapor, it was found that the average permeability to water vapor for the chipboard treated according to the invention was 0.022 g/m<2> h (0.0037 x IO-<9> kg/m<2> s Pa), and the water vapor resistance 270 x IO-<9> m<2> s Pa/kg. For untreated chipboard, the average water vapor permeability was 3.35 g/m<2> h (0.582 x 10~<9> kg/m<2> s Pa), and the water vapor resistance was 1.7 x IO-<9> m <2> s Pa/kg. The permeability to water vapor was thus noticeably lower for particle boards treated according to the invention than for untreated boards, and the water vapor resistance was correspondingly higher.
Eksempel 2 Example 2
Emisjonen av formaldehyd ble bestemt for en sponplate som var behandlet Ifølge eksempel 1, og resultatet ble sammenlig-net med emisjonen av formaldehyd fra ubehandlet sponplate. The emission of formaldehyde was determined for a chipboard that had been treated according to example 1, and the result was compared with the emission of formaldehyde from untreated chipboard.
Av sponplatene ble det saget åtte 400 x 600 x 12 mm<5> store stykker, av disse ble fire malt to ganger på begge sider med belegglngslakk Ifølge oppfinnelsen, hvor mengden av lakk sammenlagt var 300 ± 10 g/m2 . Platene ble lagt til tørk et par uker, hvoretter kantene ble beskyttet med parafin. Eight 400 x 600 x 12 mm<5> large pieces were sawn from the chipboards, four of which were painted twice on both sides with coating varnish according to the invention, where the amount of varnish in total was 300 ± 10 g/m2. The plates were left to dry for a couple of weeks, after which the edges were protected with paraffin.
Prøveplatene ble lagt i 0,2 m<5> store metallkasser, hvor luftutskiftningsfaktoren var ca. 0,5 h~<l.> Luftens temperatur var 20°C og den relative fuktigheten 85*. Formaldehydinnhol-det ble bestemt etter syv døgn i kassseluften, hvis tilførsel til kassen var 16 m2/m' . The test plates were placed in 0.2 m<5> large metal boxes, where the air exchange factor was approx. 0.5 h~<l.> The temperature of the air was 20°C and the relative humidity 85*. The formaldehyde content was determined after seven days in the box air, whose supply to the box was 16 m2/m'.
Skivene ble oppbevart i seks måneder i et lagerrom, og i denne tiden ble bestemmelsen foretatt ytterligere to ganger. Emisjonen av formaldehyd for de plater som var behandlet ifølge oppfinnelsen var 0,11 mg/m<5>, etter tre måneder ga fornyet bestemmelse 0,09 mg/m', etter ytterligere tre måneder 0,05 mg/m' , og etter fornyet måling 0,91 mg/m' , og etter ytterligere tre måneder 1,11 mg/m'. Av foregående eksempel ser man således at beleggingsmidlet som benyttes ifølge oppfinnelsen kan anvendes som en indre diffusjonssperre, i stedet for en ved veggkonstruksjoner vanligvis anvendt polyetylenhinne. The disks were kept for six months in a storage room, and during this time the determination was made two more times. The emission of formaldehyde for the boards treated according to the invention was 0.11 mg/m<5>, after three months a renewed determination gave 0.09 mg/m', after a further three months 0.05 mg/m', and after renewed measurement 0.91 mg/m', and after a further three months 1.11 mg/m'. From the previous example, it can thus be seen that the coating agent used according to the invention can be used as an internal diffusion barrier, instead of a polyethylene membrane usually used in wall constructions.
Eksempel 3 Example 3
Inneluftens relative fuktighet varierer med årstiden, men holder seg i praksis mellom 30 og 70*. Derfor vil det finne sted formforandrInger med vanlige ubehandlede treplater hvor platene krymper og utvides. The relative humidity of the indoor air varies with the season, but in practice stays between 30 and 70*. Therefore, changes in shape will take place with ordinary untreated wooden boards where the boards shrink and expand.
Ved å behandle sponplater eller andre bygningsmaterialer av tre ifølge oppfinnelsen, som beskrevet i eksempel 1, kan man få de formforandringer som skyldes årlige endringer i den relative fuktigheten og temperaturen til å skje langsommere og til å minske, og derved forbedre materialets bruksegen-skaper . By treating chipboard or other wooden building materials according to the invention, as described in example 1, the shape changes caused by annual changes in the relative humidity and temperature can be made to happen more slowly and to decrease, thereby improving the material's usability.
Når beleggingsmidlet som anvendes ifølge oppfinnelsen ble strøket på sponplatens overflate to ganger, hvor flaten fikk tørke mellom påstrykningene, avtok platens krymping til ca. 25* av formforandringen for en ubehandlet sponplate. Forsøket ble utført over to måneder ved temperatur 20" C og med en kontrollert forandring av den relative fuktighet fra 95* og 70* til 45*. Ved å behandle platenes kanter ifølge oppfinnelsen kan disse formforandringer reduseres ytterligere. Resultatene gjengis grafisk i vedlagte figur, som angir formforandringen for sponplater behandlet som nevnt ovenfor (oppsvelling i o/oo) som funksjon av den relative fuktighet (RH). Man ser at sponplater behandlet ifølge oppfinnelsen har en vesentlig mindre tendens til formforandringer enn ubehandlede .sponplater. På denne måten for-hindres at fugene beveger seg ved overflatebehandlede sponplater, og fugene kan tettes ved taplng eller på annen måte for å frembringe en enhetlig flate, f.eks. i forbindelse med en ytre veggs indre bekledning. When the coating agent used according to the invention was applied to the surface of the chipboard twice, where the surface was allowed to dry between applications, the shrinkage of the plate decreased to approx. 25* of the shape change for an untreated chipboard. The experiment was carried out over two months at a temperature of 20" C and with a controlled change in the relative humidity from 95* and 70* to 45*. By treating the edges of the plates according to the invention, these changes in shape can be further reduced. The results are reproduced graphically in the attached figure, which indicates the change in shape for chipboards treated as mentioned above (swelling in o/oo) as a function of the relative humidity (RH). It can be seen that chipboards treated according to the invention have a significantly smaller tendency to change shape than untreated chipboards. In this way, it is prevented that the joints move with surface-treated chipboard, and the joints can be sealed by tapping or in another way to produce a uniform surface, for example in connection with the inner lining of an external wall.
En sponplate som behandles ifølge oppfinnelsen blir særdeles vannavstøtende, hvorved platens tyngdeøkning ved vannbesprut-ning avtar og utgjør bare 7-15* av tyngdeøkningen for en ubehandlet plate. A chipboard that is treated according to the invention becomes particularly water-repellent, whereby the increase in weight of the board when sprayed with water decreases and amounts to only 7-15* of the increase in weight for an untreated board.
