Description

Trevirkebeskyttelsesmiddel. Wood preservative.

Foreliggende oppfinnelse vedrører et trevirkebeskyttelsesmiddel på grunnlag av et dimetyl-alkylamin og en syre og anvendelse derav, for beskyttelse av trevirke, spesielt av friskt trevirke, f.eks. friskt oppsaget sagvirke i sagbruk eller nettopp felte trestammer i skogen. The present invention relates to a wood preservative based on a dimethyl alkylamine and an acid and its use, for the protection of wood, especially fresh wood, e.g. freshly sawn timber in a sawmill or just felled tree trunks in the forest.

Det er kjent å anvende dimetylalkylaminer, 2-(metoksy-karbonylamino)benzimidazol (BCM) eller N-tridecyl-2,6-dimetyl-morfolin (tridemorf), f.eks. i form av deres salter, til beskyttelse av trevirke (EP-147 976, DE-3 138 575.3, DE-3 507 4 2 0.5). Virkningen av disse midlene er imidlertid ikke tilfredsstillende. It is known to use dimethylalkylamines, 2-(methoxycarbonylamino)benzimidazole (BCM) or N-tridecyl-2,6-dimethylmorpholine (tridemorph), e.g. in the form of their salts, for the protection of wood (EP-147 976, DE-3 138 575.3, DE-3 507 4 2 0.5). However, the effect of these means is not satisfactory.

Det ble funnet at trevirkebeskyttelsesmidler som inneholder a) et dimetylalkylamin, b) en vannløselig syre og c) en vannuløselig syre eller BCM eller c) en vannuløselig syre og 2-(metoksykarbonylamino)-benzimidazol, bortsett fra en blanding av N-tridecyl-2,6-dimetylmorfolin, dimetyl-C12-alkylamin, etoksylert nonylfenol (9 etylenoksyd pr. fenol), propylenglykol, fluorborsyre, fosforsyre, isooktansyre og vann, har en svært god virkning mot treparasitter, spesielt mot sopp, som er bedre enn virkningen av de kjente trevirkebeskyttelsesmidlene. De nye trevirkebeskyttelsesmidlene er vannløselige. De anvendes i form av vandige impregnerings-løsninger som fremstilles fra trevirkebeskyttelsesmidlene (konsentratene) ved fortynning med vann. Den foreliggende oppfinnelsen omfatter såvel konsentratene som også de fortynnede vandige løsningene (impregnerings-løsningene) som kan fremstilles derav ved fortynning med vann. De nye trevirkebeskyttelsesmidlene egner seg til beskyttelse av trevirke, spesielt av friskt trevirke, slik som det forekommer f.eks. som friskt oppsaget trevirke i sagbruk eller som nettopp felte trestammer i skogen. It was found that wood preservatives containing a) a dimethylalkylamine, b) a water-soluble acid and c) a water-insoluble acid or BCM or c) a water-insoluble acid and 2-(methoxycarbonylamino)-benzimidazole, except for a mixture of N-tridecyl-2 ,6-dimethylmorpholine, dimethyl-C12-alkylamine, ethoxylated nonylphenol (9 ethylene oxide per phenol), propylene glycol, fluoroboric acid, phosphoric acid, isooctanoic acid and water, have a very good effect against wood parasites, especially against fungi, which is better than the effect of the known wood preservatives. The new wood preservatives are water-soluble. They are used in the form of aqueous impregnation solutions that are produced from the wood preservatives (concentrates) by dilution with water. The present invention includes the concentrates as well as the diluted aqueous solutions (impregnation solutions) which can be prepared from them by dilution with water. The new wood preservatives are suitable for the protection of wood, especially of fresh wood, as occurs e.g. as freshly felled timber in a sawmill or as just felled tree trunks in the forest.

Et dimetylalkylamin er et N,N-dimetyl-N-alkylamin med en alkylrest som inneholder eksempelvis 6 til 20 C-atomer. Dimetylalkylaminer med 12 til 14 C-atomer i alkylresten blir foretrukket. Ved siden av de rene dimetylalkylaminene kan også anvendes blandinger, f.eks. blandinger av dimetyl-C12-alkylamin og dimetyl-C14-alkylamin (dimetylalkyl (C12/C14-aiuin) . A dimethylalkylamine is an N,N-dimethyl-N-alkylamine with an alkyl residue containing, for example, 6 to 20 carbon atoms. Dimethylalkylamines with 12 to 14 C atoms in the alkyl residue are preferred. In addition to the pure dimethylalkylamines, mixtures can also be used, e.g. mixtures of dimethyl-C12-alkylamine and dimethyl-C14-alkylamine (dimethylalkyl (C12/C14-aiuin) .

En vannløselig syre er eksempelvis en vannløselig uorganisk syre, f.eks. en syre av fosfor, spesielt fosfonsyre (H3PO3) , fosfinsyre (H3P02) , sure fosforsyreestere (f.eks. fosforsyre-mono- (eller -di)-alkylester, eksempelvis fosfor-syremonobutylester, fosforsyre-di-butylester), fosfonsyre-mono-alkylester eller en syre av svovel, f.eks. en sulfonsyre, eksempelvis benzo 1-mono- (eller -di)-sulfonsyre, sulfaminsyre, 4-fenolsulfonsyre. Dessuten en organisk C2-C4-karboksyl-syre, f.eks. monokarboksylsyre, eksempelvis eddiksyre, propionsyre, metoksyeddiksyre, melkesyre, glykolsyre eller polykarboksylsyre, f.eks. fumarsyre, citronsyre, maleinsyre. A water-soluble acid is, for example, a water-soluble inorganic acid, e.g. an acid of phosphorus, especially phosphonic acid (H3PO3), phosphinic acid (H3P02), acidic phosphoric acid esters (e.g. phosphoric acid mono- (or -di)-alkyl ester, e.g. phosphoric acid monobutyl ester, phosphoric acid di-butyl ester), phosphonic acid mono -alkyl ester or an acid of sulphur, e.g. a sulfonic acid, for example benzo 1-mono- (or -di)-sulfonic acid, sulfamic acid, 4-phenolsulfonic acid. Also, an organic C2-C4 carboxylic acid, e.g. monocarboxylic acid, for example acetic acid, propionic acid, methoxyacetic acid, lactic acid, glycolic acid or polycarboxylic acid, e.g. fumaric acid, citric acid, maleic acid.

En vannuløselig syre er f.eks. en alifatisk C5-C20-karboksylsyre, eksempelvis en monokarboksylsyre, heksansyre, heptansyre, oktansyre, nonansyre, dekansyre, 2-etylpentansyre, 2-etylheksansyre, 2-etylheptansyre, isooktansyre, isononan-syre, versatikksyrér (sterkt forgrenede monokarbokylsyrer), eller en dikarbokylsyre, f.eks. dekandikarboksylsyre. A water-insoluble acid is e.g. an aliphatic C5-C20 carboxylic acid, for example a monocarboxylic acid, hexanoic acid, heptanoic acid, octanoic acid, nonanoic acid, decanoic acid, 2-ethylpentanoic acid, 2-ethylhexanoic acid, 2-ethylheptanoic acid, isooctanoic acid, isononanoic acid, versatic acids (highly branched monocarboxylic acids), or a dicarboxylic acid , e.g. decane carboxylic acid.

Syrene kan også anvendes i form av sine salter, f.eks. dimetylalkylaminsaltene. De BCM inneholdende midlene kan også ved siden av den vannløselige syren dessuten inneholde en vannuløselig syre. The acids can also be used in the form of their salts, e.g. the dimethylalkylamine salts. The BCM-containing agents can also contain a water-insoluble acid in addition to the water-soluble acid.

Trevirkebeskyttelsesmidlene er blandbare med vann, danner klare løsninger med vann og har i den vanlige anvendelses-konsentrasjonen (0,5 til 10,0 vekt-%, beregnet på konsen-tratet), en pH-verdi lavere enn 7,0 ved utelukkende anvendelse av dimetylalkylamin, ved blandinger av dimetylalkylamin med tridemorf, en pH-verdi lavere enn 6, og ved blandinger av dimetylalkylamin med BCM, en pH-verdi lavere enn 3,5. De fremstilles ved blanding av de enkelte komponentene med hverandre. The wood preservatives are miscible with water, form clear solutions with water and, in the usual application concentration (0.5 to 10.0% by weight, calculated on the concentrate), have a pH value lower than 7.0 when used exclusively of dimethylalkylamine, for mixtures of dimethylalkylamine with tridemorph, a pH value lower than 6, and for mixtures of dimethylalkylamine with BCM, a pH value lower than 3.5. They are produced by mixing the individual components with each other.

Trevirkebeskyttelsesmidlene (konsentratene) er mer eller mindre viskøse løsninger, med en viskositet som kan reduseres ved tilsetning av polare løsningsmidler. Som polare løsnings-midler kan anvendes f.eks. dimetylformamid, dietylformamid, N-metylpyrrolidon, dimetylsulfoksyd, glykoler, polyglykoler, glykoleter, glykoleteracetater og alkoholer. I disse tilfellene foreligger BCM-saltet for det meste i pastaform. The wood protection agents (concentrates) are more or less viscous solutions, with a viscosity that can be reduced by adding polar solvents. Polar solvents can be used, e.g. dimethylformamide, diethylformamide, N-methylpyrrolidone, dimethylsulfoxide, glycols, polyglycols, glycol ethers, glycol ether acetates and alcohols. In these cases, the BCM salt is mostly present in paste form.

Konsentratene inneholder vanligvis (vekt-%). The concentrates usually contain (% by weight).

hvorved summen alltid skal være 100 vekt-%. whereby the sum must always be 100% by weight.

Blandingsforholdet (vekt-deler) av BCM til dimetylalkylamin ligger f.eks. mellom 1:50 til 2:1, fortrinnsvis 1:20 til 1:2. The mixing ratio (parts by weight) of BCM to dimethylalkylamine is e.g. between 1:50 to 2:1, preferably 1:20 to 1:2.

Dessuten kan vann være tilstede, som f.eks. inneholdes i de handelsvanlige formene av syrene. I tilleg kan tilsettes: fuktemidler, korrosjonsinhibitorer, fargestoffer og eventuelt bindemiddel. In addition, water may be present, such as e.g. contained in the commercially available forms of the acids. In addition, the following can be added: wetting agents, corrosion inhibitors, dyes and possibly a binder.

For å forbedre virkningsbredden av trevirkebeskyttelsesmidlene, kan de dessuten også inneholde nitrogenholdige organiske fungicider, f.eks. ytterligere morfolinderivater, som f.eks. fenpropemorf, aldimorf; guanidinderivater, som f.eks. dodecylguanidin, klorheksadin, guazatin, f.eks. imidazolderivater, f.eks. imazalil, dodecylimidazol, glyodin; pyrimidinderivater, f.eks. heksatidin, kvartære ammonium-forbindelser, f.eks. N-dodecylpyridinklorid. Dessuten kan andre fungicider anvendes i tillegg, som f.eks. 2-(tiocyan-metyltio)benzotiazol, 3-jod-2-propynylbutylkarbamat, 2-(4-tiazolyl)benzimidazol, vannløselige salter (f.eks. kalium-saltet) av N-cykloheksyl'diazeniumdioksydet. In order to improve the effectiveness of the wood preservatives, they can also contain nitrogen-containing organic fungicides, e.g. further morpholine derivatives, such as e.g. fenpropemorph, aldimorph; guanidine derivatives, such as dodecylguanidine, chlorhexadine, guazatin, e.g. imidazole derivatives, e.g. imazalil, dodecylimidazole, glyodin; pyrimidine derivatives, e.g. hexatidine, quaternary ammonium compounds, e.g. N-dodecylpyridine chloride. Furthermore, other fungicides can be used in addition, such as e.g. 2-(Thiocyanomethylthio)benzothiazole, 3-iodo-2-propynylbutylcarbamate, 2-(4-thiazolyl)benzimidazole, water soluble salts (e.g. the potassium salt) of N-cyclohexyldiazenium dioxide.

Også andre fungicider, som f.eks. furmecykloks eller benodanil, eller insekticider, som lindan eller permetrin, kan tilsettes til formuleringene, de må eventuelt innarbeides under tilsetning av emulgatorer, f.eks. etoksylerte nonyl-fenoler. Also other fungicides, such as e.g. furmecyclox or benodanil, or insecticides, such as lindane or permethrin, can be added to the formulations, they must possibly be incorporated with the addition of emulsifiers, e.g. ethoxylated nonyl phenols.

Anvendelsen av beskyttelsesmiddelet for treverket kan, alt etter hvor utsatt treverket er, foregå f.eks.: The application of the protective agent for the wood can, depending on how exposed the wood is, take place, for example:

a) ved påsprøytning av treverket med oppløsningen, a) by spraying the wood with the solution,

b) ved neddykking av treverket i oppløsningen, b) by immersing the wood in the solution,

c) ved impregnering av treverket ved hjelp av c) by impregnating the wood using

trykkforskjeller, pressure differences,

f.eks. kjeletrykk- eller dobbelvakuumimpregnering, e.g. boiler pressure or double vacuum impregnation,

d) ved påstrykning av treverket. d) when ironing the wood.

Ved følgeprodukter av tre, f.eks. oppsaget treverk, In the case of secondary products made of wood, e.g. reclaimed wood,

cellestoff, såvel som videre tekniske produkter eller også celluloseholdige materialer som utsettes for soppangrep, f.eks. mellomprodukter ved papirfremstillingen, treaktige ettårsplanter (bagasse, raps) må anvendelsen tilpasses til de tekniske mulighetene. cell material, as well as further technical products or also cellulose-containing materials which are exposed to fungal attack, e.g. intermediate products in paper production, woody annual plants (bagasse, rapeseed), the application must be adapted to the technical possibilities.

Virkningen av midlene på trevirkebeskyttelsesområdet omfatter eksempelvis: The effect of the funds in the wood protection area includes, for example:

a) muggsopp (f.eks. aspergillus niger), a) molds (e.g. aspergillus niger),

b) forråtnelsessopp (f.eks. chaetomium globosum), b) decay fungi (e.g. chaetomium globosum),

c) blåsopp (f.eks. pullularia pullulans), c) blue fungus (e.g. pullularia pullulans),

d) treødeleggende basidiomyceter (f.eks. serpula lacrymans), spesielt er virkningen svært god mot blåsopp. d) wood-destroying basidiomycetes (e.g. serpula lacrymans), especially the effect is very good against blue fungus.

Trevirkebeskyttelsesmidlene har en svært god fungicid virkning, som det fremgår av følgende forsøk. The wood preservatives have a very good fungicidal effect, as can be seen from the following experiments.

Til forsøkene ble anvendt saftfriske, nettopp oppsagede stykker av ytterved av bartre med målene 200 x 50 x 15 mm, som var dypfryst til forsøkende begynte. For the experiments fresh, freshly sawn pieces of coniferous outer wood measuring 200 x 50 x 15 mm were used, which were deep-frozen until the experiments began.

Etter opptining, (omlag 6 timer) ble trestykkene dykket ned i de løsningene som skulle anvendes i ca. 10 sekunder, stillet svakt på skrå for avdrypping og etter en mellomlagring på ca. 24 timer under normale klimabetingelser, plassert i forsøkslandskapet. Med de enkelte forsøksløsningene ble 10 prøvebrett impregnert av gangen på den ovenfor beskrevne måten. Kontrolltrestykker uten impregnering ble neddykket i rent vann. After thawing, (approx. 6 hours), the pieces of wood were immersed in the solutions to be used for approx. 10 seconds, slightly tilted for draining and after an intermediate storage of approx. 24 hours under normal climate conditions, placed in the experimental landscape. With the individual test solutions, 10 test boards were impregnated at a time in the manner described above. Control pieces of wood without impregnation were immersed in clean water.

Som prøvelandskap ble valgt ut en skyggefull eng, der gressvollen ble snauklippet før utleggingen av prøvestykkene. Prøvestykkene ble lagt ut på to kunststoffskinner i en høyde A shady meadow was selected as the test landscape, where the grass embankment was cut short before laying out the test pieces. The test pieces were laid out on two plastic rails at one height

av ca. 1 cm over gressvollen. of approx. 1 cm above the grass embankment.

De prøvebrettene som var utsatt for den ytre påvirkningen (regn) ble prøvet etter 2 mnd. (august/september). The test boards that were exposed to the external influence (rain) were tested after 2 months. (August/September).

Den fungicide virkningen ble klassifisert i fire kate-gorier på grunn av den opptredende fargingen og forandringen av treoverflaten: The fungicidal action was classified into four categories due to the occurring staining and change of the wood surface:

0 ingen vekst 0 no growth

+ svak punktvis overflatevekst + weak punctate surface growth

++ sterkere punktvis vekst ++ stronger point-wise growth

+++ store flater inntil fullstendig bevokst. +++ large areas until completely overgrown.
