og det særegne ved trebeskyttelsesmidlet i henhold til oppfinnelsen er at det dessuten inneholder 2 til 20 vektprosent N-metyl-2-pyrrolidon, beregnet i forhold til summen av de and the distinctive feature of the wood preservative according to the invention is that it also contains 2 to 20 percent by weight of N-methyl-2-pyrrolidone, calculated in relation to the sum of the
andre bestanddeler. other components.
Det har i mange år vært kjent at trevirke kan beskyttes på effektiv måte ved å impregnere det på overflaten med fungi- It has been known for many years that wood can be effectively protected by impregnating the surface with fungi-
cide og/eller insekticide midler. Impregneringen av trevirket skjer vanligvis ved påstryking, neddypping eller trykkimpreg-nering. I de fleste tilfeller bruker man de biocide midler i form av oppløsninger eller suspensjoner i alifatiske og/eller aromatiske petroleumsoppløsningsmidler, f.eks. i tungbensin ("white spirit"). cide and/or insecticidal agents. The impregnation of the wood usually takes place by brushing on, dipping or pressure impregnation. In most cases, the biocidal agents are used in the form of solutions or suspensions in aliphatic and/or aromatic petroleum solvents, e.g. in white spirit ("white spirit").
I nyere tid har man funnet midler som tillater utførelse i et eneste arbeidstrinn av på den ene side den ovenfor nevnte biodide behandling og på den annen side en "estetisk" behandling som består i å behandle trevirket med oljer eller harpikser som er farget med pigmenter. Slike midler består vanligvis av 10 til 50 vektdeler oljer eller harpikser, 1 til 6 deler pigmenter, 1 til 10 deler biocide stoffer og 40 til 85 deler av et vanlig petroleumsoppløsningsmiddel, såsom tungbensin. In recent times, means have been found which allow the execution in a single work step of, on the one hand, the above-mentioned biocidal treatment and, on the other hand, an "aesthetic" treatment which consists in treating the wood with oils or resins which are colored with pigments. Such agents usually consist of 10 to 50 parts by weight of oils or resins, 1 to 6 parts of pigments, 1 to 10 parts of biocidal substances, and 40 to 85 parts of a common petroleum solvent, such as naphtha.
Selvom disse midler, uansett som de var basert på oljer eller Although these remedies, no matter how they were based on oils or
på harpikser, med eller uten fargede pigmenter, hittil har vært ansett tilfredstillende, anser man nå at beskyttelsen mot insekter eller sopp ikke er tilfredsstillende i forhold til mengden av de innførte biocide stoffer. Undersøkelser har vist at den forholdsvis dårlige virkning av disse aktive stoffer i hovedsaken skyldtes deres dårlige inntrengning i trevirket. on resins, with or without colored pigments, has hitherto been considered satisfactory, it is now considered that the protection against insects or fungi is not satisfactory in relation to the quantity of the introduced biocidal substances. Investigations have shown that the relatively poor effect of these active substances was mainly due to their poor penetration into the wood.
Man har f.eks. konstatert at pentaklorfenol i en olje-basert blanding bare trenger inn i en dybde av 1 til 2 mm i grantre-virke. Dette tall er ennå lavere når man f.eks. bruker et preparat på basis av syntetiske harpikser av alkydtypen, da de vanskeliggjør diffusjonen av det biocide stoff gjennom delemembraner. Nærvær av fargepigmenter gjør saken enda verre, .da de tilstopper inntregningskanalene i trevirket. One has e.g. found that pentachlorophenol in an oil-based mixture only penetrates to a depth of 1 to 2 mm in spruce wood. This number is even lower when you e.g. uses a preparation based on synthetic resins of the alkyd type, as they make it difficult for the biocidal substance to diffuse through dividing membranes. The presence of color pigments makes matters even worse, as they clog the penetration channels in the wood.
Det eksisterer således et virkelig behov for å finne et middel som på merkbar måte tillater å øke inntrengningen av de biocide stoffer som finnes i blandinger for beskyttelse av trevirket. Dette middel bør ikke kreve bruken av spesielt materiale, da blandingene ofte brukes av ikke-fagfolk ved enkel påstryking, påsprøyting eller kortvarig neddypping (1 til 3 minutter). There is thus a real need to find a means which allows to noticeably increase the penetration of the biocidal substances contained in mixtures for the protection of the wood. This agent should not require the use of special material, as the mixtures are often used by non-professionals by simple application, spraying or short-term immersion (1 to 3 minutes).
Den erkjennelse som ligger til grunn for oppfinnelsen er at det faktisk er tilstrekkelig å tilsette blandingene 2 til 20 vektprosent N-metyl-2-pyrrolidon. The realization that underlies the invention is that it is actually sufficient to add 2 to 20% by weight of N-methyl-2-pyrrolidone to the mixtures.
N-metyl-2-pyrrolidon er et ugiftig oppløsningsmiddel med lite damptrykk (mindre enn 1 mm kvikksølv) som kan brukes uten risiko. Dets innhold i blandingen bør være minst lik 2% av den samlede vekt av de andre bestanddeler, idet det forutsettes at mengder på over 20 % ikke medfører tilstrekkelig forbedring av inntrengningen når man tar prisen av blandingen i betrakt-ning. N-methyl-2-pyrrolidone is a non-toxic solvent with a low vapor pressure (less than 1 mm of mercury) that can be used without risk. Its content in the mixture should be at least equal to 2% of the total weight of the other components, it being assumed that amounts of more than 20% do not lead to sufficient improvement in penetration when the price of the mixture is taken into account.
Valget av mengden av oljer eller syntetiske har<p>ikser i blandingene er avhengig av arten av den ønskede blanding. Generelt kan man klassifisere alle blandinger i tre hoved-kategorier: The choice of the amount of oils or synthetic resins in the mixtures depends on the nature of the desired mixture. In general, all mixtures can be classified into three main categories:
A) Blandinger som utelukkende skal beskytte trevirket A) Mixtures that are exclusively intended to protect the wood
B) Blandinger som torker langsomt og som skal gjore trevirket penere og beskytte det, C) Blandinger som torker hurtig og som skal gjore trevirket B) Mixtures that dry slowly and which should make the wood look nicer and protect it, C) Mixtures which dry quickly and which should make the wood
penere og beskytte det. prettier and protect it.
I tilfellet A) bruker man en liten mengde, vanligvis mellom 5 og 10 deler, av en oljeblanding av typen terpentinolje og en In case A) a small amount, usually between 5 and 10 parts, of an oil mixture of the turpentine type and a
harpiks, f.eks. abietinsyreharpiks for å fiksere de biocide stoffer. resin, e.g. abietic acid resin to fix the biocidal substances.
I tilfellet B) bruker man en stor mengde, vanligvis mellom 10 og 50 deler, av en torrende olje, f.eks. linolje, i forbindelse med en mengde torkemidler som vanligvis brukes for å torre blandingen. In case B) a large quantity, usually between 10 and 50 parts, of a drying oil, e.g. linseed oil, in conjunction with a quantity of drying agents commonly used to dry the mixture.
I tilfellet C) bruker man 10 til 50 deler av en syntetisk harpiks, særlig alkydharpiks. De harpikser som mest brukes er glycerol-ftalsyre-harpikser som eventuelt er modifisert ved podning medjtorrende fettsyrer. Bruken av slike harpikser krever, som velkjent for fagfolk, at man i blandingen innforer torkemidler som vanligvis består av kalsium-, mangan-, kobolt, zirkonium-eller blysalter av organiske syrer med mer enn 6 karbonatomer. In case C) 10 to 50 parts of a synthetic resin, particularly alkyd resin, are used. The resins most commonly used are glycerol-phthalic acid resins which are possibly modified by grafting with drying fatty acids. The use of such resins requires, as is well known to those skilled in the art, that drying agents which usually consist of calcium, manganese, cobalt, zirconium or lead salts of organic acids with more than 6 carbon atoms are introduced into the mixture.
I de to tilfeller B) og C) innforer man ofte fargepigmenter som skal farge trevirket. Avhengig av den onskede farge og nyanse bruker man 1 til 6 deler pigment, som f.eks. jernoksyder eller kjonrok. In the two cases B) and C), color pigments are often introduced to color the wood. Depending on the desired color and shade, one uses 1 to 6 parts of pigment, such as e.g. iron oxides or carbon black.
I alle tilfeller velges de biocide stoffer i det vesentlige ut fra deres fungicide og insekticide virkning på trevirket. In all cases, the biocidal substances are essentially selected based on their fungicidal and insecticidal effect on the wood.
Sopparter som forårsaker en blå-farging av trevirket, f.eks., Macrophoma pinea, Pullularia pullulans, Sclerophoma pithyophyla, er meget aktive mikroorganismer, og de biocide stoffer må derfor være spesielt aktive mot dem. Man kan eksempelvis nevne pentaklorfenol, N-(briklormetyltio)-cykiohesen-dikarboksimid, eller N-(triklormetyltio)-ftalimid. Fungal species that cause a blue staining of the wood, e.g., Macrophoma pinea, Pullularia pullulans, Sclerophoma pithyophyla, are very active microorganisms, and the biocidal substances must therefore be particularly active against them. Examples include pentachlorophenol, N-(brichloromethylthio)-cyclohesene-dicarboximide, or N-(trichloromethylthio)-phthalimide.
De insektarter som oftest forårsaker skader i trevirket er anobiider, lyctideer, hveps og midder samt maur. De bekjempes ved hjelp av slike produkter som JT-isomeren av heksaklorcyklo-heksan eller fosforsyreestere. De biocide stoffer inngår i blandingene i en mengde av 1 til 10 vektdeler. The insect species that most often cause damage to the wood are anobiids, lyctids, wasps and mites as well as ants. They are fought with the help of such products as the JT isomer of hexachlorocyclohexane or phosphoric acid esters. The biocidal substances are included in the mixtures in an amount of 1 to 10 parts by weight.
Bestanddelen som utgjor storstedelen av blandingen er ett eller flere alifatiske og/eller aromatiske petroleum-opplosnings-stoffer, såsom tungbensin, alkylbenzener o.s.v. De utgjor 40 til 85 deler av blandingen. The component that makes up the majority of the mixture is one or more aliphatic and/or aromatic petroleum solvents, such as naphtha, alkylbenzenes, etc. They make up 40 to 85 parts of the mixture.
De folgende utforelseseksempler av oppfinnelsen viser tydelig den forbedring av beskyttelsen av trevirket som oppnås ved innforing av N-metyl-2-pyrrolidon i blandingene. The following embodiments of the invention clearly show the improvement in the protection of the wood which is achieved by introducing N-methyl-2-pyrrolidone into the mixtures.
Eksempel 1. Example 1.
Prover av trevirke ble behandlet ifolge fransk norm X2-Bois-doc Samples of wood were treated according to the French norm X2-Bois-doc
71. Uten å omtale i detaljer denne norm som fagfolk uten 71. Without mentioning in detail this norm that professionals without
,v vanskelighet kan konsultere, er arbeidsmåten som folger: Prover av furuved i form av rektangulære parallelle pipeder med kvadratisk tverrsnitt (20 x 4 x 4 cm) ble behandlet i 3 min. ved neddypping i de blandinger som skal undersokes. Mån uttar prover (8 x 4 x 1 cm) som utsettes for kulturer av en sopp dyrket isolert i 4 uker i dyrkingskolber ved 26°C og under 85% fuktighet. Man bruker tre arter for å utfore forsokene ,v difficulty can consult, the working method is as follows: Samples of pine wood in the form of rectangular parallel pipes with a square cross-section (20 x 4 x 4 cm) were treated for 3 min. by immersion in the mixtures to be examined. Moon takes samples (8 x 4 x 1 cm) which are exposed to cultures of a fungus grown in isolation for 4 weeks in culture flasks at 26°C and under 85% humidity. Three species are used to carry out the experiments
- Pallularia pullulens - Pallularia pullulens
- Macrophoma pinea - Macrophoma pinea
- Sclerophoma pithyophila - Sclerophoma pithyophila
For å bestemme den minste beskyttelsesdybde i mm, deler man proven i fire stykker og måler den sokte storrelse på de utskårede avsnitt. Nærvær av sopp kan konstateres ved en fargning som er synlig for oyet^To determine the minimum protection depth in mm, the sample is divided into four pieces and the desired size is measured on the cut sections. The presence of fungi can be ascertained by a color that is visible to the eye^
En annen rekke av målinger utfores med prover som var lagret i 40 dager ved 25°C og 6% fuktighet, etter en inkubasjonstid for soppen på 4 uker ved 26°C og 85% fuktighet. Another series of measurements is carried out with samples that were stored for 40 days at 25°C and 6% humidity, after an incubation period for the fungus of 4 weeks at 26°C and 85% humidity.
En forste rekke av forsok ble utfort med blandinger som inneholdt N-metyl-2-pyrrolidon, mén som ikke inneholdt biocide stoffer, viste at opplosningsmidlet ikke i. seg selv har noen fungicid virkning. A first series of tests was carried out with mixtures containing N-methyl-2-pyrrolidone, but which did not contain biocidal substances, showing that the solvent does not in itself have any fungicidal effect.
Man har også undersokt folgende blandinger: The following mixtures have also been investigated:
Preparat I (kjent teknikk) Preparation I (known technique)
Tilfelle B: uten N-metyl-2-pyrrolidon Case B: without N-methyl-2-pyrrolidone
Preparat II (oppfinnelsen)- Preparation II (the invention)-
Tilfelle B: identisk med det forangående, men inneholdende dessuten 10 vektprosent N-metyl-2-pyrrolidon i forhold til de andre bestanddeler. Case B: identical to the preceding, but also containing 10% by weight of N-methyl-2-pyrrolidone in relation to the other components.
Preparat III (kjent teknikk) Preparation III (prior art)
Tilfelle C: uten N-metyl-2-pyrrolidon Case C: without N-methyl-2-pyrrolidone
Preparat IV (oppfinnelsen) Preparation IV (the invention)
Tilfelle Cs identisk med et forangående, men inneholdende dessuten N-metyl-2-pyrrolidon 10 vektprosent i forhold til de andre bestanddeler. Case Cs identical to the preceding one, but also containing N-methyl-2-pyrrolidone 10% by weight in relation to the other components.
De minste beskyttelsesdybder erholdt med disse preparater er angitt i den folgende tabell: The minimum protection depths obtained with these preparations are indicated in the following table:
