Description
Foreliggende oppfinnelse' vedrører glassmateriale som har The present invention relates to glass material which has
et pyrolytisk dannet, lystransmitterende, solstrålebeskyttende metalloksydbelegg. a pyrolytically formed, light-transmitting, solar-protective metal oxide coating.
Bruken av vindusglass som bærer et solstrålebeskyttende belegg, er velkjent ved vindusinnsetning i bygninger for å redusere bygningens solvarmeøkning, spesielt under varmt, solrikt vær, for at temperaturen i bygningen lett kan holdes ved et nivå som f.eks. er behagelig for de som befinner seg i bygningen, og som kan tolereres av eventuelle datamaskiner eller annet temperaturfølsomt elektronisk utstyr som befinner seg i bygningen. The use of window glass carrying a solar protective coating is well known in windowing in buildings to reduce the building's solar heat gain, especially during hot, sunny weather, so that the temperature in the building can easily be maintained at a level such as is comfortable for those in the building, and can be tolerated by any computers or other temperature-sensitive electronic equipment in the building.
Fra europeisk patent nr. 0.075.516 Al er det f.eks. kjent From European patent no. 0.075.516 Al it is e.g. known
å forsyne glass med et solstrålebeskyttende belegg av titandioksyd avsatt i en mengde av størrelsesorden 140 mg/m 2, hvilket tilsvarer en tykkelse på ca. 35 nm. Kjent vindusglass med et belegg av titandioksyd med tykkelse 35-40 nm gir en effektiv beskyttelse for solstråler og gir ved refleksjon en metallfargenyanse p.g.a. interferenseffekter. Kommersielt er det meget viktig at et slikt belegg forårsaker en farge-nyanse ved refleksjon som er nøytral eller på annen måte estetisk akseptabel. Uheldigvis er kjente belegg av titandioksyd med en tykkelse opp til 40 nm benyttet for dette formål for tynne til å ha tilstrekkelig abrasjonsbestandighet slik at produktet har en utilstrekkelig brukbar levetid. to provide glass with a solar protective coating of titanium dioxide deposited in an amount of the order of 140 mg/m 2 , which corresponds to a thickness of approx. 35 nm. Known window glass with a coating of titanium dioxide with a thickness of 35-40 nm provides effective protection against solar rays and gives a metallic color shade due to reflection. interference effects. Commercially, it is very important that such a coating causes a color shade upon reflection that is neutral or otherwise aesthetically acceptable. Unfortunately, known coatings of titanium dioxide with a thickness of up to 40 nm used for this purpose are too thin to have sufficient abrasion resistance so that the product has an insufficient useful life.
Det ville være mulig å gi ytterligere abrasjonsbestandighet til belegget ved å gjøre det tykkere. Det er f.eks. funnet at titandioksydbelegg med en tykkelse i området 50-60 nm kan ha en tilfredsstillende abrasjonsbestandighet for de aktuelle formål. Økning av tykkelsen på et slikt belegg vil imidlertid ha den virkning av dets fargetonerefleksjon forandres, og et titandioksydbelegg med en tykkelse på 50-60 nm gir en ubehagelig, gulaktig fargerefleksjon. It would be possible to provide additional abrasion resistance to the coating by making it thicker. It is e.g. found that titanium dioxide coatings with a thickness in the range of 50-60 nm can have a satisfactory abrasion resistance for the relevant purposes. Increasing the thickness of such a coating will, however, have the effect of changing its color tone reflection, and a titanium dioxide coating with a thickness of 50-60 nm gives an unpleasant, yellowish color reflection.
Formålet med foreliggende oppfinnelse er å tilveiebringe glassmateriale som bærer et pyrolytisk dannet, lystransmitterende, solstrålebeskyttende metalloksydbelegg slik at beleggfargen ved betraktning under refleksjon, The purpose of the present invention is to provide glass material that carries a pyrolytically formed, light-transmitting, solar-protective metal oxide coating so that the coating color when viewed under reflection,
kan varieres på en måte som ikke fullstendig er uavhengig av beleggets tykkelse. can be varied in a way that is not completely independent of the thickness of the coating.
Ifølge foreliggende oppfinnelse er det tilveiebragt et glassmateriale med et pyrolytisk dannet, lystransmitterende, solstrålebeskyttende metalloksydbelegg inneholdende tinnoksyd og titanoksyd, og dette materialet er kjennetegnet ved at minst 9 5 vekt-% av metallkationene i belegget består av tinn og titan, at de relative mengdeforhold av tinn og titan-loner er slik at belegget gis en brytningsindeks som ikke er større enn 2,2 og at belegget omfatter minst 3 0% tinn og minst 30% titan beregnet som vekt-% av det respektive dioksyd i belegget. According to the present invention, a glass material is provided with a pyrolytically formed, light-transmitting, solar-protective metal oxide coating containing tin oxide and titanium oxide, and this material is characterized by the fact that at least 95% by weight of the metal cations in the coating consist of tin and titanium, that the relative proportions of tin and titanium ions are such that the coating is given a refractive index that is not greater than 2.2 and that the coating comprises at least 30% tin and at least 30% titanium calculated as % by weight of the respective dioxide in the coating.
Brytningsindeksen for et tynt, pyrolytisk dannet titanoksyd-belegg er ca. 2,3. Ved anvendelse av foreliggende oppfinnelse blir beleggets brytningsindeks som et hele redusert ved tilsetning av tilstrekkelige tinnioner, og følgelig kan belegget ifølge oppfinnelsen fremstilles til den samme optiske tykkelse som, men til en større faktisk tykkelse enn, et belegg av vesentlig rent titandioksyd. Det vil forstås at abrasjonsbestandigheten til et slikt belegg er avhengig av beskaffenheten og den aktuelle tykkelse til belegget, mens eventuelle interferenseffekter p.g.a. belegget vil avhenge av dets optiske tykkelse. Den optiske tykkelsen The refractive index for a thin, pyrolytically formed titanium oxide coating is approx. 2.3. When using the present invention, the refractive index of the coating as a whole is reduced by the addition of sufficient tin ions, and consequently the coating according to the invention can be produced to the same optical thickness as, but to a greater actual thickness than, a coating of essentially pure titanium dioxide. It will be understood that the abrasion resistance of such a coating depends on the nature and relevant thickness of the coating, while any interference effects due to the coating will depend on its optical thickness. The optical thickness
til et belegg som bestemmer dets refleksjonsegenskaper, er gitt ved to ganger dets faktiske tykkelse multiplisert med dets brytningsindeks. Følgelig tilveiebringer foreliggende oppfinnelse•et middel for å forbedre abrasjonsbestandigheten for et belegg av nevnte type, mens dets farge ved refleksjon reguleres slik at det resulterende belegget har bedre aldringsegenskaper. Abrasjonsbestandighet for et belegg ifølge oppfinnelsen forbedres sammenlignet med et titandioksydbelegg av samme optiske tykkelse, fordi foreliggende belegg har en større virkelig tykkelse og også to a coating which determines its reflective properties is given by twice its actual thickness multiplied by its refractive index. Accordingly, the present invention provides a means of improving the abrasion resistance of a coating of said type, while controlling its color by reflection so that the resulting coating has better aging properties. Abrasion resistance of a coating according to the invention is improved compared to a titanium dioxide coating of the same optical thickness, because the present coating has a greater actual thickness and also
fordi tilsetningen av tinnioner modifiserer beleggets beskaffenhet på en måte som er nyttig for forbedring av abrasjonsbestandigheten. Det er således mulig å simulere et tynt titandioksydbelegg, men med bedre aldringsegenskaper. because the addition of tin ions modifies the nature of the coating in a way that is useful for improving abrasion resistance. It is thus possible to simulate a thin titanium dioxide coating, but with better aging properties.
Brytningsindeksen til et belegg av nevnte type kan måles The refractive index of a coating of the aforementioned type can be measured
ved hjelp av en klassisk ellipsometriteknikk som beskrevet i "Thin Film Phenomena", K.L. Chopra, McGraw Hill, 1969, using a classical ellipsometry technique as described in "Thin Film Phenomena", K.L. Chopra, McGraw Hill, 1969,
side 738-741, og henvisninger i foreliggende sammenheng til spesifikke brytningsindeksverdier er henvisninger til verdier målt ved hjelp av denne teknikk, idet målingen er foretatt ved bruk av natrium D-lys. pages 738-741, and references in the present context to specific refractive index values are references to values measured using this technique, the measurement being made using sodium D-light.
For å teste beleggets abrasjonsbestandighet kan det anvendes et ringformet resiproserende gnidningselement med en indre diameter på 2 cm og en ytre diameter på 6 cm for oppnåelse av et gnidningsoverflateareal på 25 cm 2 og dannet av en filtpute på et ringformet metallelement. Gnidningselementet anbringes i et belastet rør (vekt for sammensetningen: 1,7 kg) som glir vertikalt i en understøttelse. Konstant kontakt oppnås dermed mellom gnidningselementet og prøvestykket. Hullet gjennom det ringformede metallelementet danner et reservoar for en vandig suspensjon av knust sand med en midlere korndiameter på 0,1 mm som får strømme ut mellom filtputen og det belagte glassmateriale som testes. Under-støttelsen som bærer gnidningselementet, resiproseres ved hjelp av et veivsystem med en amplitude på 3 cm ved en frekvens på 1Hz. Etter en viss tid oppnås et slitasjemønster som utgjøres av meget nær hverandre beliggende riper med ikke-ødelagt belegg mellom disse, fulgt eventuelt av fullstendig eller vesentlig fullstendig fjerning av belegget. Spesifikke eller sammenlignende henvisninger i foreliggende sammenheng til abrasjonsbestandighet, er henvisninger til abrasjonsbestandighet målt ved denne test. To test the abrasion resistance of the coating, an annular reciprocating rubbing element with an inner diameter of 2 cm and an outer diameter of 6 cm can be used to achieve a rubbing surface area of 25 cm 2 and formed by a felt pad on an annular metal element. The rubbing element is placed in a loaded tube (weight for the composition: 1.7 kg) which slides vertically in a support. Constant contact is thus achieved between the rubbing element and the test piece. The hole through the annular metal element forms a reservoir for an aqueous suspension of crushed sand with an average grain diameter of 0.1 mm which is allowed to flow out between the felt pad and the coated glass material being tested. The support carrying the rubbing element is reciprocated by means of a crank system with an amplitude of 3 cm at a frequency of 1 Hz. After a certain time, a wear pattern is achieved which consists of very close to each other scratches with undamaged coating between them, possibly followed by complete or substantially complete removal of the coating. Specific or comparative references in the present context to abrasion resistance are references to abrasion resistance measured by this test.
I de mest foretrukne utførelser av foreliggende oppfinnelse In the most preferred embodiments of the present invention
er de relative mengdeforhold for tinn- og titanioner i belegget slik at belegget gis et brytningsindeks som er minst 1,9. Dette sørger for at det vil være en høy grad av refleksjon av synlig lys i belegget. are the relative quantity ratios for tin and titanium ions in the coating so that the coating is given a refractive index of at least 1.9. This ensures that there will be a high degree of reflection of visible light in the coating.
De relative mengdeforhold for tinn- og titanioner i belegget er med fordel slik at belegget gis et brytningsindeks som ikke er større enn 2,15. Dette gis anledning for en til-svarende større virkelig tykkelse for en gitt optisk tykkelse på belegget. The relative proportions of tin and titanium ions in the coating are advantageously such that the coating is given a refractive index that is not greater than 2.15. This gives rise to a correspondingly greater real thickness for a given optical thickness of the coating.
Belegget omfatter minst 30% tinn og minst 30% titan beregnet som vekt-% av det respektive dioksyd i belegget. Det er funnet at dette gir det beste kompromiss mellom sol-strålebeskyttelsesegenskapene til belegget (som stort sett skyldes tilstedeværelsen av titan) og reduksjon i brytningsindeks og økning i abrasjonsbestandighet (som skyldes tilstedeværelsen av tinn). For å oppnå den beste abrasjonsbestandigheten er det foretrukket at belegget omfatter minst 4 0% tinn beregnet som vekt-% av tinnoksyd i belegget. The coating comprises at least 30% tin and at least 30% titanium calculated as % by weight of the respective dioxide in the coating. This has been found to provide the best compromise between the solar radiation protection properties of the coating (due largely to the presence of titanium) and the reduction in refractive index and increase in abrasion resistance (due to the presence of tin). In order to achieve the best abrasion resistance, it is preferred that the coating comprises at least 40% tin calculated as % by weight of tin oxide in the coating.
I oppfinnelsens mest foretrukne utførelser er beleggets tykkelse og de relative mengdeforhold av tinn- og titanioner i belegget slik at det oppnås interferensforbedring av refleksjon av synlig lys i bølgelengdeområde mindre enn 500 nm. På denne måten vil glassmaterialet vise en metall-fargetone ved betraktning i vanlig dagslys ved refleksjon fra den belagte siden. In the most preferred embodiments of the invention, the thickness of the coating and the relative quantity ratios of tin and titanium ions in the coating are such that interference improvement of the reflection of visible light in the wavelength range of less than 500 nm is achieved. In this way, the glass material will show a metallic tint when viewed in normal daylight by reflection from the coated side.
Belegget bæres fortrinnsvis av plateglass. Et slikt glass kan være klart glass, eller det kan være opakt glass, The coating is preferably carried by plate glass. Such glass may be clear glass, or it may be opaque glass,
f.eks. for bruk som utvendige fasadekledningspaneler for bygninger ved gulvnivåer. Utførelser av oppfinnelsen hvorved plateglasset er tonet glass, f.eks. bronseglass, har fordel-aktige lysabsorberende egenskaper. e.g. for use as exterior cladding panels for buildings at floor levels. Embodiments of the invention whereby the plate glass is tinted glass, e.g. bronze glass, has advantageous light-absorbing properties.

beskrevet i større detalj i følgende eksempler. described in greater detail in the following examples.
Testprøve Test sample
Et titandioksydbelegg med en tykkelse på 4 5 nm kan dannes A titanium dioxide coating with a thickness of 45 nm can be formed
på glass som beskrevet i eksempel 1 i britisk patent 1.397.741 ved pyrolyse av titanylacetylacetonat. Det er funnet at når det er dannet på en slik måte, har titandioksydbelegget et brytningsindeks på 2,3, og således en optisk refleksjons-tykkelse på 207 nm. Når abrasjonsbestandigheten for dette belegget ble testet, ble det funnet at belegget og i det minste det sentrale område av det slitasjeutsatte areal, on glass as described in example 1 of British patent 1,397,741 by pyrolysis of titanyl acetylacetonate. It has been found that when formed in such a way, the titanium dioxide coating has a refractive index of 2.3, and thus an optical reflection thickness of 207 nm. When the abrasion resistance of this coating was tested, it was found that the coating and at least the central area of the wear area,
var vesentlig fullstendig fjernet i løpet 5 minutter. was substantially completely removed within 5 minutes.
Eksempel 1 Example 1
Et oksydbelegg omfattende 40% tinn og 60% titan beregnet An oxide coating comprising 40% tin and 60% titanium calculated
som vekt-% av det respektive dioksyd i belegget, ble dannet ved pyrolyse på et varmt glass-substrat av en oppløsning inneholdende titanylacetylacetonat og tinndibutyldiacetat. Det resulterende belegg hadde et brytningsindeks på 1,9 og ble formet til en tykkelse på 55 nm slik at det hadde den samme optiske tykkelsen som belegget i testprøven. Når abrasjonsbestandigheten for dette belegget ble testet, ble det etter abrasjon i 30 minutter funnet at noen riper var synlige i belegget når belegget ble betraktet gjennom et mikroskop. as % by weight of the respective dioxide in the coating, was formed by pyrolysis on a hot glass substrate of a solution containing titanyl acetylacetonate and tin dibutyl diacetate. The resulting coating had a refractive index of 1.9 and was formed to a thickness of 55 nm so that it had the same optical thickness as the coating in the test sample. When the abrasion resistance of this coating was tested, after abrasion for 30 minutes, it was found that some scratches were visible in the coating when the coating was viewed through a microscope.
Belegget viste en metallisk fargetone ved refleksjon. The coating showed a metallic hue upon reflection.
I en variant av dette eksempelet ble belegget dannet på fargetonet glass for derved å oppnå en reduksjon i lystransmisjon. In a variant of this example, the coating was formed on tinted glass to thereby achieve a reduction in light transmission.
E ksempel 2 Example 2
Et 6 mm tykt bånd av nylig dannet, varmt, klart float-glass ble ført gjennom en beleggingsstasjon i en hastighet på A 6 mm thick ribbon of newly formed, hot, clear float glass was passed through a coating station at a speed of
8,5 m pr. minutt. Atmosfæren i beleggingsstasjonen hadde en midlere temperatur på ca. 300°C og båndet som kom inn i denne stasjonen, hadde en midlere temperatur på ca. 600°C. 8.5 m per minute. The atmosphere in the coating station had an average temperature of approx. 300°C and the tape that entered this station had an average temperature of approx. 600°C.
Belegg-forløperoppløsningen ble fremstilt som følger: The coating precursor solution was prepared as follows:
Denne oppløsning ble sprøytet ved en hastighet på 120 liter pr. time for dannelse av et belegg med en tykkelse på 4 2 nm på glassbåndet. This solution was sprayed at a rate of 120 liters per hour for the formation of a coating with a thickness of 4 2 nm on the glass tape.
Den beregnede vektsammensetning for belegget var 27% tinndioksyd og 53% titandioksyd, og belegget hadde et brytningsindeks på 1,9. The calculated weight composition for the coating was 27% tin dioxide and 53% titanium dioxide, and the coating had a refractive index of 1.9.
Med innfallende lys på den belagte siden av en plate skåret fra dette båndet, var platens lystransmisjon 74,2%, With incident light on the coated side of a plate cut from this band, the light transmission of the plate was 74.2%,
