Description
Foreliggende oppfinnelse vedrører et trebeskyttelsesmiddel som inneholder vann, i vann oppløst kobber - eller sinkkomplekser, samt syre som binder kobber eller sink i tre. The present invention relates to a wood preservative which contains water, copper or zinc complexes dissolved in water, and acid which binds copper or zinc in wood.
Tidligere kjent er trebeskyttelsesmiddel som inneholder aminkompleksdannende metaller, vanligvis kobber eller sink, samt ammoniakk og kullsyre. En lignende trebeskyttelseopp-løsning kan fremstilles for eksempel slik at ammmoniakk om-settes med kobberkarbonat, hvoretter den dannede oppløsning stabiliseres med ammoniumkarbonat samt ved behov med kullsyre. Previously known are wood preservatives that contain amine complex-forming metals, usually copper or zinc, as well as ammonia and carbonic acid. A similar wood protection solution can be prepared, for example, by reacting ammonia with copper carbonate, after which the formed solution is stabilized with ammonium carbonate and, if necessary, with carbonic acid.
Slik er det som trebeskyttelsesmiddel kjent ulike substans-blandinger på basis av for eksempel kobber eller sink. Kobber kan da bindes i tre og også på andre måter enn ved utfelling i form av karbonat. De såkalte CCA-salter ble ut-viklet på 1930-tallet og har siden dette vært ålment anvendt for å beskytte tre mot forråtnelse. Slike CCA-salter inneholder kobber, krom og arsenik. Kobber anvendes på grunn av sin fungicide virkning, mens arsenik anvendes hovedsaklig for å frembringe en insekticid virkning. Krom igjen anvendes for å binde kobber i tre. CCA-saltene gir en god beskyttelse mot forråtnelse, men er skadelige for omgivelsene. Various substance mixtures based on, for example, copper or zinc are known as wood preservatives. Copper can then be bound in wood and also in other ways than by precipitation in the form of carbonate. The so-called CCA salts were developed in the 1930s and have since been widely used to protect wood against decay. Such CCA salts contain copper, chromium and arsenic. Copper is used because of its fungicidal effect, while arsenic is mainly used to produce an insecticidal effect. Chromium is again used to bind copper in wood. The CCA salts provide good protection against decay, but are harmful to the environment.
Ulempen med disse tidligere kjente trebeskyttelsesmidler er at de ikke gir treet tilstrekkelig dimensjonsstabilitet. Denne ulempe har man forsøkt å eliminere ved å anvende vannuløselige trebeskyttelsesmiddel, som er oppløst i et organisk løsningsmiddel for impregnering. Slike organiske oppløsninger trenger ikke inn i treet like godt som vann-oppløsninger, organiske oppløsninger forhøyer dessuten prisen på trebeskyttelsesmiddelet og gjør det meget brann-farlig. Ved å anvende mikroemulsjoner kan man miske mengden av organisk løsningsmiddel, men en slik mikroemulsjon er tross alt betydelig dyrere enn en vannoppløsning. The disadvantage of these previously known wood preservatives is that they do not give the wood sufficient dimensional stability. This disadvantage has been tried to be eliminated by using water-insoluble wood preservatives, which are dissolved in an organic solvent for impregnation. Such organic solutions do not penetrate the wood as well as water solutions, organic solutions also increase the price of the wood preservative and make it highly flammable. By using microemulsions, the amount of organic solvent can be mixed, but such a microemulsion is, after all, significantly more expensive than a water solution.
Foreliggende oppfinnelse har såkalt til hensikt å frembringe et på vann basert trebeskyttelsesmiddel som er billig, giftfritt og trenger godt inn i treet, som ikke utvannes lett fra treet, og som medfører at vannabsorbering i treet minsker. The present invention has the so-called purpose of producing a water-based wood preservative which is cheap, non-toxic and penetrates well into the wood, which is not easily leached from the wood, and which causes water absorption in the wood to decrease.
Foreliggende oppfinnelse har dessuten til hensikt å frembringe et trebeskyttelsesmiddel hvori virkningen av kobber og sink er effektivere enn tidligere. Middelet i henhold til oppfinnelsen kan videre anvendes i fungicide malinger, overflatebehandlingsmidler og vekstpotter. The present invention also aims to produce a wood preservative in which the effect of copper and zinc is more effective than previously. The agent according to the invention can also be used in fungicidal paints, surface treatments and plant pots.
Oppfinnelsens hovedsaklige særtrekk fremgår av vedlagte patentkrav. The main distinctive features of the invention appear from the attached patent claims.
Nå har det uventet vist seg at nevnte målsettinger og for-deler kan oppnås med trebeskyttelsesmidler som inneholder vann, i vann oppløst kobber - og/eller simkkomplekser samt en organisk vannoppløselig eller i. varan miscellerende polymer som stabiliserer kobber og/eller sink i tre, som minst delvis trenger inn i. tre sam* som'inneholder'syre— grupper. Now it has unexpectedly turned out that the aforementioned objectives and benefits can be achieved with wood preservatives that contain water, water-dissolved copper and/or zinc complexes as well as an organic water-soluble or i.v. miscellarizing polymer that stabilizes copper and/or zinc in wood, which at least partially penetrates into. three sam* which'contain'acid— groups.
Også zirkoniumkomplekser kan anvendes sammen med Cu- og/ eller Zn-kompleks, da zirkoniumkomplekser øker polymerens vannresistens samt forsterker kobberet og/eller sinkens effekt mot mikroorganismer. Zr-komplekset kan tilsettes som separat salt, for eksempel som ammoniumzirkoniumkarbonat eller også fremstilles på tilsvarende måte som Cu- og Zn-amin-polymer-syre-kompleks. Zirconium complexes can also be used together with Cu and/or Zn complexes, as zirconium complexes increase the polymer's water resistance and reinforce the copper and/or zinc's effect against microorganisms. The Zr complex can be added as a separate salt, for example as ammonium zirconium carbonate or also prepared in a similar way as a Cu and Zn amine polymer acid complex.
Som en forbindelse som komplekserer kobber eller sink anvendes med fordel ammoniakk, men man kan også anvende et primært, sekundært eller tertiært amin substituert med lavere alkyl som metyl, etyl eller propyl, eller cyclisk amin så som piperidin, morfolin eller lignende, som fremstilt i patentkrav 4, hvorved fremkomst i treet av kobber-eller sinkpolymeren som løser seg dårlig i vann eller er uløselige i vann, kommer av at kompleksdanneren fordunster i tørkningsfasen eller at treets sure omgivelser nøytraliser-er den anvendte kompleksdanneren. As a compound that complexes copper or zinc, ammonia is advantageously used, but one can also use a primary, secondary or tertiary amine substituted with lower alkyl such as methyl, ethyl or propyl, or cyclic amine such as piperidine, morpholine or the like, as prepared in patent claim 4, whereby appearance in the wood of the copper or zinc polymer which dissolves poorly in water or is insoluble in water, comes from the complex former evaporating in the drying phase or the wood's acidic environment neutralizing the used complex former.
Som organisk polymer kan det anvendes en hvilket som helst slik polymer som delvis eller helt trenger inn i tre, som er vannoppløselig eller miscellerer i vann og som inneholder karboksylgrupper, fenolgrupper og/eller As an organic polymer, any such polymer can be used which partially or completely penetrates wood, which is water-soluble or miscellulates in water and which contains carboxyl groups, phenolic groups and/or
Pol = Polymergruppe (bindingsatom karbon) Pol = Polymer group (bond atom carbon)
R<1>= alifatisk, alicycklisk eller aromatisk radikal eller et derivat som inneholder disse funksjonelle grupper, eller polymer R<1>= aliphatic, alicyclic or aromatic radical or a derivative containing these functional groups, or polymer
R = liksom R<1>og også H R = like R<1>and also H
Polymerens inntrengning i treet kan reguleres med molekylvekten. Hvis polymerens molekylvekt ikke går over 2 000, trenger det helt inn i treet og om molekylvekten ligger over dette, skjer kun en delvis inntrenging, hvorved en over flateimpregnering er resultatet. Denne molekylvektgrense varierer for ulike polymerer i henhold til deres konfigura-sjon. For eksempel for polyetylenglykol er den ca. 2 000. The penetration of the polymer into the wood can be regulated with the molecular weight. If the polymer's molecular weight does not exceed 2,000, it penetrates completely into the wood and if the molecular weight is above this, only partial penetration occurs, whereby an over-surface impregnation is the result. This molecular weight limit varies for different polymers according to their configuration. For example, for polyethylene glycol, it is approx. 2,000.
Polymerens vannoppløselighet reguleres med hydrofilitets-graden, med andre ord med antall syregrupper eller andre hydrofile grupper, som hydroksyl-, amid- eller amingrupper, den inneholder. The water solubility of the polymer is regulated by the degree of hydrophilicity, in other words by the number of acid groups or other hydrophilic groups, such as hydroxyl, amide or amine groups, it contains.
Polymeren trenger ikke være helt vannoppløselig, det er tilstrekkelig om den er delvis vannoppløselig, hvorved den kan emulgeres i vann til misceller. Polymeren som inneholder hydrofobe grupper, forminsker dessuten treets opp- The polymer does not have to be completely water-soluble, it is sufficient if it is partially water-soluble, whereby it can be emulsified in water to form micelles. The polymer, which contains hydrophobic groups, also reduces the wood's
svelling. swelling.
Polymeren kan være syntetisk eller naturpolymer. Som synt-etiske polymere kan anvendes radikalpolymere, kondensasjons polymere eller addisjonspolymere. The polymer can be synthetic or natural polymer. Radical polymers, condensation polymers or addition polymers can be used as synthetic polymers.
Som eksempel for radikalpolymere kan nevnes polymeriserende (met)akryl-itakon-, malein-, vinyl og (met)allyl-fosfonat-, fosforsyrer og ulike -arseniksyrer. Disse syregrupper kan videre frembringes eller bindes ved hjelp av en egnet etter behandlingsreaksjon for den ferdige radikalpolymer, spesielt i det tilfelle at den egnede syremonomer ikke finnes tilgjengelig i handelen. Examples of radical polymers include polymerizing (meth)acrylic itaconic, maleic, vinyl and (meth)allyl phosphonate, phosphoric acids and various arsenic acids. These acid groups can further be produced or bound by means of a suitable post-treatment reaction for the finished radical polymer, especially in the event that the suitable acid monomer is not commercially available.
Som komonomer kan anvendes for eksempel andre (met)allyl- og akrylforbindelser, både hydrofobe (for eksempel vinylalkyl-eter eller (met)akrylester) og hydrofile og videre monomere som inneholder andre enn hydrofile funksjonelle grupper, for eksempel amido-, amino-, 0H-, halogen- og nitrilgrupper. As comonomers, for example, other (meth)allyl and acrylic compounds can be used, both hydrophobic (for example, vinyl alkyl ether or (meth)acrylic ester) and hydrophilic, and further monomers that contain other than hydrophilic functional groups, for example amido-, amino-, OH, halogen and nitrile groups.
Blant anvendbare kondensasjonspolymere kan menes polyestere, for eksempel fosforsyrediolestere eller deres derivater, polyamider, aminoharpikser, så som urea-, melanin-, cyanam-id-, guanidin-, benzoguanaminharpikser osv. hvilke aminoharpikser fremstilles ved kondensering med et aldehyd eller keton eller med alkohol eteriserte aldehydkondensater, fenolharpikser, spesielt resoler, samt muligens blandings-polymere, forutsatt at disse inneholder en eller flere av nevnte syregrupper. Useful condensation polymers include polyesters, for example phosphoric acid diol esters or their derivatives, polyamides, amino resins, such as urea, melanin, cyanamide, guanidine, benzoguanamine resins, etc. which amino resins are produced by condensation with an aldehyde or ketone or with alcohol etherified aldehyde condensates, phenolic resins, especially resols, and possibly mixed polymers, provided that these contain one or more of the aforementioned acid groups.
Som eksempel på addisjonspolymere kan nevnes polyetylen-iminderivater, polyuretan og polyetylenoksydderivater. Examples of addition polymers include polyethylene imine derivatives, polyurethane and polyethylene oxide derivatives.
Blant naturpolymere kan nevnes lignosulfonatderivater, styr-kelsesderivat, f.eks. fosforisert styrkelse, alginat, karb-oksymetylcellulose, pektin og karragen. Among natural polymers, mention may be made of lignosulfonate derivatives, starch derivatives, e.g. phosphorous strengthening, alginate, carboxymethyl cellulose, pectin and carrageenan.
Ekvivalentforholdet for syregruppene i polymere og kobberet eller sinken i komplekset er 1:10 til 10:1, fortrinnsvis 1:2. The equivalent ratio of the acid groups in polymers and the copper or zinc in the complex is 1:10 to 10:1, preferably 1:2.
Trebeskyttelsesmiddelet i henhold til oppfinnelsen inneholder fordelaktig ca. 0,05 til 0,08 mol kobber eller sink, The wood preservative according to the invention advantageously contains approx. 0.05 to 0.08 moles of copper or zinc,
0,1 til 0,2 mol enverdige syregrupper i polymeren og 0,2 til 0,4 mol NH3i en liter impregneringsoppløsning. 0.1 to 0.2 mol monovalent acid groups in the polymer and 0.2 to 0.4 mol NH3 in one liter of impregnation solution.
Et spesielt fordelaktig trebeskyttelsesmiddel er en vann-oppløsning av sinktetra-ammonium-polyakrylat. A particularly advantageous wood preservative is a water solution of zinc tetra-ammonium polyacrylate.
Et spesielt fordelaktig trebeskyttelsesmiddel fås når nevnte blandinger tilsettes filicinekstrakt av ormebregner, som er en blanding av floroglysinderivater. A particularly advantageous wood preservative is obtained when filicin extract of worm ferns, which is a mixture of phloroglycine derivatives, is added to the aforementioned mixtures.
I ormebregner (Filices) forekommer generelt floroglysinderivat som er monocycliske filicinsyrer og aspidinoler samt di og tricycliske derivater av disse. Floroglysinderivat kan separeres fra bregner ved ekstraksjon, og et slikt ekstrakt i hvilket floroglysinderivatene utgjør de viktigste bestanddelene , kalles råfilicin og råaspidin. Filicinsyrer, aspidinoler og deres derivater fås rene fra bregneekstrakt ved separasjon, men de kan også fremstilles syntetisk. Til nå har bregneekstrakt og dets bestanddeler kun vært anvendt som bekjempningsmiddel mot skadedyr så som gnagere (jmfr. Fl utlegningsskrift 54 850) samt som legemiddel mot bendelorm og endoparasitter. In worm ferns (Filices) there are generally phloroglysine derivatives which are monocyclic filicic acids and aspidinols as well as di and tricyclic derivatives of these. Phloroglysin derivatives can be separated from ferns by extraction, and such an extract in which the phloroglysin derivatives form the most important components is called crude filicin and crude aspidin. Filicic acids, aspidinols and their derivatives are obtained pure from fern extract by separation, but they can also be produced synthetically. Until now, fern extract and its components have only been used as a means of combating pests such as rodents (cf. Fl explanatory note 54 850) and as a medicine against tapeworms and endoparasites.
Nå er det kommet fram at nevnte bregneekstrakt kan anvendes i blandinger i henhold til oppfinnelsen, hvorved de øker trebeskyttelsesmiddelets virkning mot forråtnelse og insek-ter . It has now emerged that said fern extract can be used in mixtures according to the invention, whereby they increase the effect of the wood preservative against decay and insects.
Oppfinnelsen illustreres i det følgende ved hjelp av eks-empler. The invention is illustrated in the following by means of examples.
Eksempel 1 Example 1
Impregneringsoppløsningen fremstilles ved å nøytralisere polyakrylsyre (molekylvekt 1 600), fremstillet av 2 mol akrylsyre (144 g), med NaOH og ved å tilføre den nøytrali-serte oppløsningen 1 mol (250 g) kobbersulfat. Det utfelte kobberpolyakrylatet separeres ved filtrering og 4 mol (272 g 25 %) ammoniakk tilsettes. Den erholdte oppløsningen fortynnes slik at den inneholder 0,052 mol (3,3 g)Cu<2>+/l-Denne oppløsnings fungicide virkning ble utprøvd med muld-kassemetoden i henhold til NWPC:s (Nordisk WoodPreservation Council) standard 1.4.1.2/70, hvorved følgende resultat ble oppnådd. The impregnation solution is prepared by neutralizing polyacrylic acid (molecular weight 1,600), prepared from 2 mol of acrylic acid (144 g), with NaOH and by adding 1 mol (250 g) of copper sulfate to the neutralized solution. The precipitated copper polyacrylate is separated by filtration and 4 moles (272 g 25%) of ammonia are added. The obtained solution is diluted so that it contains 0.052 mol (3.3 g)Cu<2>+/l- This solution's fungicidal effect was tested with the mold-box method according to NWPC's (Nordic WoodPreservation Council) standard 1.4.1.2/ 70, whereby the following result was obtained.
Klosser av overflatetre av størrelse 2 x 2 x 1,5 cm<3>, ble impregnert med den overfor beskrevede oppløsning. De impregnerte klosser fikk stå å renne av, ble veiet, tørket og veiet på nytt. Klossene ble begravet i mulden og etter 24 uker ble de gransket. Blocks of surface wood of size 2 x 2 x 1.5 cm<3> were impregnated with the solution described above. The impregnated blocks were allowed to drain, weighed, dried and weighed again. The bricks were buried in the soil and after 24 weeks they were examined.
Vekttapene fremgår av følgende tabell: The weight losses appear in the following table:
Vekttapet for de klosser som ble behandlet med Cu-polyakrylat var en antydning mindre enn for de klosser som ble behandlet med Kemira "K 33" og betydelig mindre enn for de som ble behandlet med Cu-naftenat, selv om Cu-retensjonen var lavere i akrylatet. Dette henviser til kobberets og polyakrylatetes synergiske effekt. The weight loss for the bricks treated with Cu polyacrylate was slightly less than for the bricks treated with Kemira "K 33" and significantly less than for those treated with Cu naphthenate, although the Cu retention was lower in the acrylate. This refers to the synergistic effect of copper and polyacrylate.
Ved utvanningsforsøket var 12 % av Cu-c.lyakrylatet kobber utvasket i vannet. In the leaching test, 12% of the Cu-c.lyacrylated copper was leached into the water.
Eksempel 2 Example 2
Impregneringsoppløsningen ble fremstilt analogt med eksempel 1 av kopolymer som var fremstilt av akrylsyre-metylmetakryl-atblanding, kopolymeren inneholdt 72 mol % metylmetakrylat. The impregnation solution was prepared analogously to example 1 from copolymer which was prepared from an acrylic acid-methyl methacrylate mixture, the copolymer contained 72 mol% methyl methacrylate.
Vannabsorbering og dimensjonsforandring for de prøvebiter som ble impregnert med løsningen utgjorde 60 % av absorb-ering og dimensjonsforandring for de ubehandlede prøve-biter. Water absorption and dimensional change for the test pieces that were impregnated with the solution accounted for 60% of absorption and dimensional change for the untreated test pieces.
I utvanningsforsøket var 9 % av kobberet utvasket i vannet. In the leaching test, 9% of the copper was leached into the water.
I muld-kasseforsøket var de med oppløsning impregnerte klossenes vekttap de samme som de klosser som ble impregnert med oppløsningen i henhold til eksempel 1. In the mold box test, the weight loss of the solution-impregnated bricks was the same as the bricks which were impregnated with the solution according to example 1.
Eksempel 3 Example 3
I en oppløsning som ble fremstilt i likhet med oppløsningen i eksempel 1 ble tilsatt 0,014 mol alkylammoniumklorid. Impregneringens retensjon var 2 kg kobber/m<3>overflatetre. De impregnerte klossenes vekttap i muld-kasseforsøket var 21 % mindre enn de ubehandledes klosser vekttap. I utvann-ingsforsøket var 12 % av kobberet utvasket i vannet. In a solution prepared in the same way as the solution in example 1, 0.014 mol of alkylammonium chloride was added. The impregnation's retention was 2 kg copper/m<3>surface wood. The weight loss of the impregnated bricks in the soil box test was 21% less than the weight loss of the untreated bricks. In the leaching experiment, 12% of the copper was leached into the water.
Eksempel 4 Example 4
En oppløsning ble framstilt som inneholdt per liter 0,07 6 mol sink, polymer framstilt av 0,152 mol alkylsyre og 0,303 mol ammoniakk. Impregneringens retensjon var 3 kg sink/m<3>overflatetre. De impregnerte klossenes vekttap i muld-kassef orsoket var 30 % mindre enn de ubehandlede klossers vekttap. A solution was prepared containing per liter 0.07 6 mol zinc, polymer prepared from 0.152 mol alkyl acid and 0.303 mol ammonia. The retention of the impregnation was 3 kg zinc/m<3>surface wood. The weight loss of the impregnated bricks in the soil-case trial was 30% less than the weight loss of the untreated bricks.
Eksempel 5 Example 5
En oppløsning ble fremstilt som inneholdt per liter 0,052 mol kobber, kopolymer fremstilt av 0,052 mol maleinanhydrid og 0,052 mol styren samt 0,208 mol ammoniakk. Impregneringens retensjon var 2 kg kobber/m<3>overflatetre. A solution was prepared which contained per liter 0.052 mol of copper, copolymer made from 0.052 mol of maleic anhydride and 0.052 mol of styrene and 0.208 mol of ammonia. The impregnation's retention was 2 kg copper/m<3>surface wood.
