Description
Trebeskyttelsesmiddel.
Kjente trebeskyttelsesmidler, som spesielt er egnet til anvendelse for trekon-struksjoner utendørs og har den egenskap å fikseres i treet, består av alkalifluorider, alkalikromater og/eller alkaliarsenater resp. de tilsvarende ammoniumsalter.
Ved siden av deres gode egenskap for de forskjellige impregneringsfremgangs-måter (kjeletrykkimpregnering, traugjen-nomfuktning, osv) består en spesiell fordel ved slike alkalifluoridholdige trebeskyttelsesmidler deri at ikke det samlede fluorid fikseres i treet, men at en del av fluoridet under brukstiden av det impregnerte tre forblir diffusjonsdyktig og derved er i stand til — spesielt etter vanntiltreden — å trenge inn i tresonen, som ved selve im-pregneringsprosessen ikke ble omfattet. Disse midlers virkning mot trebeskadigende sopper og insekter er god; bare ved visse lavere sopparter, som er kjent som for-råtnelsesfrembringere er det nødvendig med forholdsvis høye doseringer.
Det er nu blitt funnet at trebeskyttel-sesvirkningen av de i og for seg kjente blandinger på basis av vannoppløselige 6-verdige kromoksygenforbindelser, alkalifluorider og alkaliarsenater resp. alkalimetaarsenater kan forbedres betraktelig når det i de ovennevnte blandinger erstattes alkalifluoridene i det minste delvis med vannoppløselige fluorider av kobolt eller nikkel.
Den nye kobolt- og/eller nikkelfluorid-hydratholdige trebeskyttelsesblanding har en spesielt god virkning mot frembringeren av forråtnelse, idet i motsetning til de tid-ligere kjente midler er det ikke nødvendig med noen høyere dosering. Trebeskyttel-sesmidlene ifølge oppfinnelsen utmerker seg derfor ved siden av deres gode virkning også på grunn av deres økonomi.
Oppløseligheten av disse fluoridhydrater av kobolt og/eller nikkel i impregne-ringsoppløsningene kan eventuelt økes ved tilsetning av flussyre. Flussyren kan tilset-tes i form av sure fluorider og/eller frigjø-res fra fluorider ved tilsetning av syrer som kromsyre eller alkalibisulfat.
Nærværet av nikkel- og/eller koboltfluoridhydrater i impregneringsoppløsnin-gene kan likeledes oppnås ved at man lar deres dannelse foregå i vandig oppløsning, idet man f. eks. går ut fra andre nikkel-resp. koboltsalter (f. eks. sulfater, klorider, nitrater eller karbonater) og samtidig til-setter alkalifluorider.
Som vannoppløselig kromoksygenforbindelser anvendes alkaliforbindelsene av kromsyre og polykromsyre, spesielt natri-umkromat, kaliumkromat, ammoniumkro-mat, natriumdikromat, kaliumdikromat og ammoniumdikrornat. Således kan det også anvendes blandinger av disse forbindelser eventuelt også i blanding med anhydrit av kromsyre Cr03. Trebeskyttelsesblandingene skal inneholde 20 til 80 vektsprosent av kromatet, fortrinnsvis 30 til 50 vektsprosent beregnet på den samlede blanding.
Ved siden av de nøytrale og sure fluorider av alkaliionene, idet begrepet alkali her medomfatter ammonium, kan det anvendes borfluorider såvel som vannopplø-selige silikofluorider (f. eks. ammonium-, magnesium-, sinksilikofluorider osv.) resp. blandinger av disse fluorider, idet ved et samlet innhold av trebeskyttelsesmidler på fluorider fra 20 til 80 vektsprosent, fortrinnsvis 25 til 60 vektprosent, idet det det karakteriserende er at i det minste en del av de nevnte fluorider er erstattet med fluoridhydrater av kobolt og/eller nikkel. Vanligvis skal innholdet av nikkel- resp. koboltfluoridhydrater utgjøre 2 til 20 vektsprosent, fortrinnsvis 3 til 10 vektsprosent, beregnet på trebeskyttelsesblandin-gen. Alkaliarsenater resp. alkalimetaarsenater kan foreligge i mengder fra 0 til 40 vektsprosent, fortrinnsvis i mengder fra 15 til 30 vektsprosent.
Anvendelseskonsentrasj onene av trebeskyttelsesmidlet ifølge oppfinnelsen ret-ter seg etter opptagelsesevnen av det tre som skal impregneres, resp. etter impreg-neringsfremgangsmåten.
For anvendelse ved kj eletrykkfuktning anvendes f. eks. vandige oppløsninger med et innhold mellom 1 og 6 vektsprosent av trebeskyttelsesmidlet. Ved impregnering ved håndverksmessige fremgangsmåter (f. eks. strykning, sprøytning osv.) anvendes konsentrasjoner mellom 10 og 25 vektsprosent.
Fikseringen av nikkel og/eller kobolt innen rammen av saltblandingene som er sammensatt ifølge oppfinnelsen i treet er praktisk talt fullstendig. Disse stoffers virkning beholdes da også ved påkjenning av treet ved forvitring eller ved rennende vann, f. eks. i kjøletårn.
Eksempel 1.
Det blandes
40 deler kaliumbikromat,
15 deler natriumfluorid
og 40 deler kaliumbifluorid med 5 deler nikkelfluoridhydrat (Ni<F>2.4H20).
Med en 4 pst.ig oppløsning av denne saltblanding fullfuktes furusplinttreet iføl-ge DIN 52.176, blad 2, og utlutbarheten bestemmes. Nikkelet er praktisk talt fiksert 100 pst.
Eksempel 2.
40 deler kaliumbikromat,
7 deler kromsyre,
15 deler dinatriumarsenat
og 31,6 deler ammoniumbifluorid blandes med 5 ; deler nikkelsulfat og 1,4 deler kaliumbifluorid.
Fukte|- og utlutningsforsøket ifølge DIN 52.176, blad 2, på en 40 pst.ig oppløs-ning fuktet tre viser likeledes en praktisk talt fullstendig fiksering av nikkelet.
Eksempel 3.

20 deler nikkelfluoridhydrat (NiF2.4H20).
Med,' en 4 pst.-ig oppløsning av denne saltblanding fullfuktes furusplinttreet ifølge DIN 52.176, blad 2, og utlutbarheten bestemmes. Nikkel er praktisk talt fiksert 100 pst.,<1>
Eksempel 4.

Mens grenseverdien for fluor-krom-saltet mot grurmxåte ligger ved 40 kg salt/ m.3 tre kunne det ved tilsetning av kobolt- resp. nikkelfluoridhydrater tilsetnin-gen senkes til 20 kg/m3.
Ved fluor-krom-arsensalter ligger grenseverdien mot grunnråte ved 60 kg/ m3.

og grenseverdien mot frembringeren av grunnråte bestemmes. Ved den ovennevnte blanding ble det bestemt grenseverdi ved koboltsalttilsetningen til 15—20 kg/m3.
Claims (2)
1. Trebeskyttelsesmiddel mot plan te - og dyriske skadeorganismer med et innhold av alkalidikromater og/eller kroma-ter og/eller kromsyrer i mengder fra 20 til 80 vektprosent, alkaliarsenater og/eller alkalimetaarsenater i mengder fra 0 til 40 vektprosent og vannoppløselige fluorider i mengder fra 20 til 80, fortrinnsvis 25 til 60, vektprosent, idet begrepet alkali medomfatter ammonium, karakterisert ved at en del av de vannoppløselige fluorider foreligger i form av fluoridhydratene av kobolt og/eller nikkel.
2. Trebeskyttelsesmiddel ifølge påstand 1, med et innhold av fluoridhydrater av kobolt og/eller nikkel i mengder fra 2 til 20, fortrinnsvis fra 3 til 10, vektsprosent.
