Abstract
Trebeskyttelsesmiddel som inneholder kobber, et alkanolamin og en syre, hvis kobbersalt er vannuløselig, og fremgangsmåte for impregnering av tre.Wood preservative containing copper, an alkanolamine and an acid, the copper salt of which is water-insoluble, and the process for impregnating wood.
Description
Foreliggende oppfinnelse gjelder et trebeskyttelsesmiddel som inneholder en vandig løsning av et kobberkompleks med et alkanolamin og en monomer, organisk forbindelse (syre), hvis kobbersalt er vannuløselig. Trebeskyttelsesmidler på basis av uorganiske kobberforbindelser med alkanolamin som kompleks-danner er kjent (EP-89 958). De har den ulempe at etter fiksering av kobberet i treet på den ene siden, kan opptre en kobberutvasking med vann på ca. 10 %, og på den annen side at midlets virksomhet overfor treødeleggende basidiomyceter på tross av det høye kobberinnholdet i sammenligning med kobber-og kromatholdige salter (CK-, CKB-typer) er mindre. Kobber-fikseringen hos de kjente trebeskyttelsesmidlene med en pH-verdi i løsningene over 8 skjer i treet fra pH ca. 7,5-8,0. The present invention relates to a wood preservative which contains an aqueous solution of a copper complex with an alkanolamine and a monomeric, organic compound (acid), the copper salt of which is water insoluble. Wood preservatives based on inorganic copper compounds with alkanolamine as a complex-former are known (EP-89 958). They have the disadvantage that after fixing the copper in the wood on one side, a copper leaching with water of approx. 10%, and on the other hand, that despite the high copper content, the agent's activity against wood-destroying basidiomycetes is less in comparison with copper- and chromate-containing salts (CK, CKB types). The copper fixation in the known wood preservatives with a pH value in the solutions above 8 takes place in the wood from a pH of approx. 7.5-8.0.
Det danner seg herved basiske kobberforbindelser, for eksempel kobberhydroksyd. Disse kobberforbindelsene er stabile til en pH-verdi på ca. 5,0, men kan så igjen oppløses av fortynnede syrer, slike som foreligger i sur jord eller surt regn, slik at det under disse betingelsene foregår en forhøyet utvasking fra treet. This forms basic copper compounds, for example copper hydroxide. These copper compounds are stable at a pH value of approx. 5.0, but can then be dissolved again by diluted acids, such as are present in acid soil or acid rain, so that under these conditions there is an increased leaching from the wood.
Det ble nå funnet at de ovennevnte ulempene bortfaller når det anvendes vann-løselige trebeskyttelsesmidler på basis av en blanding av kobberforbindelser som er kompleksdannet med alkanolaminer og en monomer organisk forbindelse (syrer) eller deres salter som danner vannuløselige salter med kobber. Et alkanolamin er eksempelvis et mono-Ci- Ca-alkanolamin, for eksempel etanolamin. En forbindelse, spesielt en syre, som danner et vannuløselig kobbersalt, er eksempelvis sorbinsyre, benzosyre, substituert benzosyre, dehydracetsyre, 5-nitroisoftalsyre, oksalsyre, salicylanilid, amfotensider eller deres blanding. En substituert benzosyre er for eksempel benzosyre som er substituert en gang eller to ganger, eksempelvis med halogen (Cl, Br, J), NO2, OH eller Ci- Ca-alkyl (for eksempel mestyl), fortrinnsvis i orto-stilling. Amfotensider er eksempelvis fungicide amfotensider, for eksempel en Cs-C20-alkylaminokarboksylsyre, eksempelvis Ci 0-Ci 4-alkylamino-C2-Ca - karboksylsyre, et alkylaminoalkylglycin, for eksempel Ca-C20 - alkylaminoalkylglycin, eksempelvis Ci 0-Ci 4-alkylamino-C2-C3-alkyl-glycin eller Ci 0-Ci 4-alkylamino-C2-C3-alkylamino-C2- Ca - alkyl-glycin. Syren kan også foreligge i form av sitt vann-løselige salt, for eksempel alkalisalt, alkanolaminsalt. It was now found that the above-mentioned disadvantages disappear when water-soluble wood preservatives are used based on a mixture of copper compounds which are complexed with alkanolamines and a monomeric organic compound (acids) or their salts which form water-insoluble salts with copper. An alkanolamine is, for example, a mono-Ci-Ca-alkanolamine, for example ethanolamine. A compound, especially an acid, which forms a water-insoluble copper salt is, for example, sorbic acid, benzoic acid, substituted benzoic acid, dehydracetic acid, 5-nitroisophthalic acid, oxalic acid, salicylanilide, amphotensides or their mixture. A substituted benzoic acid is, for example, benzoic acid which is substituted once or twice, for example with halogen (Cl, Br, J), NO2, OH or Ci-Ca-alkyl (for example mestyl), preferably in the ortho position. Amphotensides are, for example, fungicidal amphotensides, for example a Cs-C20-alkylaminocarboxylic acid, for example Ci 0-Ci 4-alkylamino-C2-Ca - carboxylic acid, an alkylaminoalkylglycine, for example Ca-C20 - alkylaminoalkylglycine, for example Ci 0-Ci 4-alkylamino- C2-C3-alkyl-glycine or C10-C14-alkylamino-C2-C3-alkylamino-C2-C6-alkyl-glycine. The acid can also exist in the form of its water-soluble salt, for example alkali salt, alkanolamine salt.
De fortynnede, vandige løsningene (impregneringsløsningene) av disse midlene har en pH-verdi på 8 til 11, fortrinnsvis 9-10. De vannuløselige kobbersaltene av de ovennevnte syrene er også bestandige ved pH-verdier under 5. De virker godt mot basidiomycet-sopper og de forminsker utvaskingen av kobber. The diluted aqueous solutions (impregnation solutions) of these agents have a pH value of 8 to 11, preferably 9-10. The water-insoluble copper salts of the above-mentioned acids are also stable at pH values below 5. They work well against basidiomycete fungi and they reduce the leaching of copper.
Som kompleksdannere egner seg av økonomiske grunner spesielt monoetanolamin. Fremstillingen av de nye trebeskyttelsesmidlene er også mulig med andre alkanolaminer, for eksempel isopropanolamin, 1,1-, 1,2-di-aminoetanol, amino-etyletanolamin, dietanolamin, dimetyletanolamin. Herved tilmåles mengden av det tilsatte alkanolaminet fordelaktig slik at den er tilstrekkelig for kompleksdannelse av kobberet (1 gram-atom kobber behøver ialt 4 ekvivalenter amin) og det dessuten eventuelt dannes alkanolamin-salter av de organiske syrene, slik at det innstiller seg en pH-verdi på 8 eller mer, fortrinnsvis 9 til 10 i den vandige impregneringsløsningen. Monoethanolamine is particularly suitable as a complexing agent for economic reasons. The production of the new wood preservatives is also possible with other alkanolamines, for example isopropanolamine, 1,1-, 1,2-di-aminoethanol, amino-ethylethanolamine, diethanolamine, dimethylethanolamine. In this way, the amount of the added alkanolamine is advantageously measured so that it is sufficient for complex formation of the copper (1 gram-atom of copper requires a total of 4 equivalents of amine) and alkanolamine salts are also possibly formed from the organic acids, so that a pH value of 8 or more, preferably 9 to 10 in the aqueous impregnation solution.
pH-verdien i trebeskyttelsesmidlene og den fortynnede, vandige impregneringsløsningen kan eventuelt innstilles uavhengig av kompleksdannelsen også ved tilsetning av alkalier, ammoniakk eller andre vannløselige aminer. The pH value in the wood preservatives and the diluted, aqueous impregnation solution can optionally be adjusted independently of the complex formation also by adding alkalis, ammonia or other water-soluble amines.
De nye trebeskyttelsesmidlene kan eventuelt inneholde vanlige, ytterligere bestanddeler som korrosjonsinhibitorer, The new wood preservatives may possibly contain common, additional components such as corrosion inhibitors,
for eksempel isonansyre henholdsvis deres salter.for example isonanoic acid or their salts.
Det anbefales å tilsette borsyre og/eller borater til trebeskyttelsesmidlene, for ved hjelp av disse diffusjonsdyktige bestanddelene også å oppnå en impregnering av ikke tilgjengelige treområder (kjerneved). It is recommended to add boric acid and/or borates to the wood preservatives, in order to achieve an impregnation of inaccessible wood areas (heartwood) with the help of these diffusible components.
De nye trebeskyttelsesmidlene kan også foreligge som mer eller mindre viskøs væske, som pasta eller i fast form. The new wood preservatives can also be available as a more or less viscous liquid, as a paste or in solid form.
De vannfortynnbare midlene inneholder, i konsentrert form, kobberet, beregnet som element, ialt i en mengde fra 1 til 15 vekt%. The water-dilutable agents contain, in concentrated form, the copper, calculated as an element, in a total amount of from 1 to 15% by weight.
Egnede konsentrater inneholder eksempelvis (i vekt%)Suitable concentrates contain, for example (in weight%)
2,5 til 50 % Cu-forbindelse2.5 to 50% Cu compound
10 til 50 % alkanolamin10 to 50% alkanolamine
10 til 30 % organisk forbindelse (syre)10 to 30% organic compound (acid)
opptil 30 % av forbindelse med et fungicid virkende anion up to 30% of compound with a fungicidal active anion
(borsyre),(boric acid),
hvorved summen blir 100 (vekt%), såvel som eventuelt under-ordnede mengder av andre bestanddeler som aminer, ammoniakk, korrosjonsinhibitorer og om nødvendig vann, hvis andel imidlertid kan holdes liten og i det vesentlige tjener håndteringen. Oppfinnelsen strekker seg imidlertid i samme grad til de impregneringsløsningene med tilsvarende liten enkelt-konsentrasjon som kan fremstilles ved fortynning med vann. whereby the sum becomes 100 (weight%), as well as possibly subordinate amounts of other components such as amines, ammonia, corrosion inhibitors and, if necessary, water, the proportion of which can however be kept small and essentially serves the handling. However, the invention extends to the same extent to the impregnation solutions with a correspondingly low individual concentration which can be prepared by diluting with water.
Innholdet av den organiske forbindelse (syre) oppgår eksempelvis til 8 til 35 %, for eksempel 10 til 30 %, spesielt 10 til 25 %. Forbindelsen kan også foreligge i form av dens kobbersalt. The content of the organic compound (acid) is, for example, 8 to 35%, for example 10 to 30%, especially 10 to 25%. The compound may also exist in the form of its copper salt.
Oppfinnelsen forklares ved hjelp av følgende eksempler. The invention is explained by means of the following examples.
Klasser av furusplintvedklosser ved ble impregnert med impregneringsløsninger som var fremstilt av trebeskyttelsesmidlene ved fortynning med vann. Etter impregneringen ble treklassene utvasket med vann, mengden av utvasket kobber bestemt og grenseverdiene for den konsentrasjon av impregnerings-løsning fastslått, ved hvilke treklassene etter impregneringen og etter utvaskingen av basidiomycet-sopper ikke lenger ble angrepet. Classes of pine splinter wood blocks were impregnated with impregnation solutions which were prepared from the wood preservatives by diluting them with water. After the impregnation, the wood classes were washed out with water, the amount of leached copper determined and the limit values for the concentration of impregnation solution determined, at which the wood classes after the impregnation and after the washing out were no longer attacked by basidiomycete fungi.

De nevnte syrene kan også anvendes i blandinger med hverandre. Således anbefales det å anvende biocide amfotensider og fungicide eller insekticide syrer i blandinger. The mentioned acids can also be used in mixtures with each other. Thus, it is recommended to use biocidal amphotensides and fungicidal or insecticidal acids in mixtures.
Fikseringen av kobberet fra midlet ifølge oppfinnelsen i treet er avsluttet i løpet av 2 til 4 uker under normal-betingelser, avhengig av temperatur. Ved tilførsel av energi, spesielt varm damp, kan fikseringen akselereres. The fixation of the copper from the agent according to the invention in the wood is completed within 2 to 4 weeks under normal conditions, depending on the temperature. By supplying energy, especially hot steam, the fixation can be accelerated.
Furuklosser ble impregnert med en anvendelseskonsentrasjon på 4 % av midlet ifølge eksempel 1 og behandlet 2 timer senere med varm damp på 100°C, til klossene hadde en temperatur på minst 90°C (2 timer). Klossene ble deretter utvasket med vann og den utvaskede Cu-mengden bestemt i forhold til Cu-innholdet i klossene. Den totale utvasking av Cu oppgikk til 2,5 %. Pine blocks were impregnated with a use concentration of 4% of the agent according to example 1 and treated 2 hours later with hot steam at 100°C, until the blocks had a temperature of at least 90°C (2 hours). The bricks were then washed out with water and the leached Cu amount determined in relation to the Cu content in the bricks. The total leaching of Cu amounted to 2.5%.
