Description
Oppfinnelsen vedrører vandig impregneringsmiddel for tre eller trematerialer på basis av kombinasjoner av salter av forskjellige addukter av maleinsyreanhydrid på tørkende oljer oog/eller slike oljeoppbyggende umettede fettsyrer og/eller på hydroksy1 fr ie syntetisk fremstilte estere av disse fettsyrer med di- eller polyoler, idet kombinasjonsdeltager-ene adskiller seg ved forskjellig penetreringsforhold. The invention relates to an aqueous impregnating agent for wood or wood materials based on combinations of salts of various adducts of maleic anhydride on drying oils and/or such oil-building unsaturated fatty acids and/or on hydroxy1 free synthetically produced esters of these fatty acids with di- or polyols, the combination participating - are distinguished by different penetration ratios.
Tre eller trematerialer har i lengere tid blitt behandlet med forskjellige impregneringsmidler for å nedsette disse materialers tendens mot sopp-, bakterie- eller insektangrep samt mot innvirkning av svingningene av fuktighetsinnholdet. Slike trebeskyttelsesmidler som fortrinnsvis skal være utvaskbar- resp. diffusjonsfaste påføres enten direkte fra vandig emulsjon eller vandig oppløsning eller fra oppløs-ninger i organiske oppløsningsmidler. Eventuelt tilsettes for forbedring av fuktighetsregulerende virkning også vandige polymerdispersjoner eller alkydharpiksoppløsninger i oppløs-ningsmidler og/eller vann til impregneringen. Ved alle disse systemer er inntrengingsdybden av midlet i treet ikke tilstrekkelig til å sikre de ønskede effekter. Understøtt-ende tilsetninger som fuktemidler øker riktignok inntrengningsdybden, er imidlertid uheldige f.eks. med hensyn til utvaskbarheten eller fuktighetsreguleringen. Wood or wooden materials have for a long time been treated with various impregnation agents to reduce the tendency of these materials against fungal, bacterial or insect attack as well as against the impact of fluctuations in the moisture content. Such wood preservatives which should preferably be washable - resp. diffusion solids are applied either directly from aqueous emulsion or aqueous solution or from solutions in organic solvents. Optionally, to improve the moisture-regulating effect, aqueous polymer dispersions or alkyd resin solutions in solvents and/or water are also added to the impregnation. With all these systems, the penetration depth of the agent in the wood is not sufficient to ensure the desired effects. Supporting additives such as wetting agents do indeed increase the penetration depth, but are unfortunate, e.g. with regard to washability or moisture regulation.
Fra DE 28 38 930 - C 2 resp. EP 0 137 126-A 1 er det kjente vandige impregneringsmidler for tre og trematerialer på basis av lavmolekylære dien(ko )polymerisater, som med tilsvarende modifisering overføres til en vannoppløselig form. Ifølge DE 28 38 930 - C 2 omsettes epoksyderte butadienpolymere med aminer og reaksjonsproduktene gjøres vannfortynnbare med saltdannelse med syrer. Den manglende tørking av disse produkter skal forbedres ifølge EP 0 137 126 -A 1 ved at man i stedet for det kationiske aminaddukt anvender karboksylerte dienpolymerisater, som gjøres vannf ortynnbare ved saltdannelse med baser. From DE 28 38 930 - C 2 or EP 0 137 126-A 1 are known aqueous impregnating agents for wood and wood materials based on low molecular weight diene(co)polymers, which with corresponding modification are transferred to a water-soluble form. According to DE 28 38 930 - C 2, epoxidized butadiene polymers are reacted with amines and the reaction products are made water-dilutable by salt formation with acids. The lack of drying of these products is to be improved according to EP 0 137 126 -A 1 by using carboxylated diene polymers instead of the cationic amine adduct, which are made water-dilutable by salt formation with bases.
Produkter på basis av dienpolymerisater viser riktignok ovenfor den tidligere kjente teknikkens stand fordeler med hensyn til inntrengningsdybden, en stor ulempe ligger imidlertid i en meget manglende klimabestandighet, hvorav det fremkommer en gråfarging av den impregnerte treoverflate. Dessuten har impregneringer på denne basis også etter tørking en uheldig lukt, som lar en anvendelse i lukkede rom ikke være gunstig. Products based on diene polymers do indeed show advantages over the state of the art in terms of penetration depth, but a major disadvantage lies in a very poor climate resistance, which results in graying of the impregnated wood surface. In addition, impregnations on this basis also have an unpleasant smell after drying, which makes an application in closed rooms unfavorable.
Det ble nå funnet at man får impregneringer av utmerket kvaliet og optimal permanentvirkning, når impregneringsmidlet som bærer inneholder blandinger av utvalgte vannoppløselige salter av addukter av maleinsyreanhydrid til tørkende oljer og/eller til umettede fettsyrer ogg/eller deres hydroksylfrie estere resp. salter av tilsvarende addukthalvestere med monoalkoholer, idet blandingens komponenter erkarakterisertved en forskjellig inntrengningsdybde. It has now been found that impregnations of excellent quality and optimal permanent effect are obtained when the impregnating agent as the carrier contains mixtures of selected water-soluble salts of adducts of maleic anhydride to drying oils and/or to unsaturated fatty acids and/or their hydroxyl-free esters resp. salts of corresponding adduct half-esters with monoalcohols, the components of the mixture being characterized by a different penetration depth.
Oppfinnelsen vedrører følgelig vandige impregneringsmidler for tre eller trematerialer inneholdende et vannoppløselig bærermaterlal og trebeskyttelsesvirksomme stoffer samt i impregneringsteknikken vanlige tilsetningsstoffer, idet impregneringsmidlene erkarakterisert vedat det vannoppløse-lige bærermaterial består av blandinger av addukter av maleinsyreanhydrid på tørkende oljer og/eller på slike oljer oppbyggende umettede fettsyrer og/eller på hydroksylf rie syntetisk fremstilte estere av disse fettsyrer med di- eller polyoler, hvis anhydridstruktur er oppsluttet med vann og/eller fortrinnsvis ved monoalkoholer med 1 til 10 karbonatomer, og hvis ene syretall på 40 til 280 mg KOH/g tilsvarende karboksylgrupper delvis eller fullstendig er nøytrali-sert med baser med den forholdsregel at kombinasjonen minst inneholder en komponent med en penetreringsverdi , som definert i beskrivelsen, på mindre enn 2 timer og minst en andre komponent med en penetrer ingsverdi på mer enn 2,5 timer. The invention therefore relates to aqueous impregnating agents for wood or wooden materials containing a water-soluble carrier material and substances active in wood protection as well as additives common in the impregnation technique, the impregnating agents being characterized in that the water-soluble carrier material consists of mixtures of adducts of maleic anhydride on drying oils and/or unsaturated fatty acids that build up on such oils and/or on hydroxyl-free synthetically produced esters of these fatty acids with di- or polyols, whose anhydride structure is closed with water and/or preferably with monoalcohols with 1 to 10 carbon atoms, and whose single acid number is 40 to 280 mg KOH/g corresponding carboxyl groups is partially or completely neutralized with bases with the precaution that the combination contains at least one component with a penetration value, as defined in the description, of less than 2 hours and at least one other component with a penetration value of more than 2.5 hours.
Som penetrer ingsverdi angis den tid som en 18#-ig vandig oppløsning av et kaliumsalt av adduktet krever, fullstendig å fukte en spesifisert filterplate (se nedenfor) av størrelse 50 x 100 mm, som står på smalsiden i et250 cm<5>begerglass, idet impregneringsoppløsningens mengde i begerglasset utgjør 25 g (f.eks. 60 min/100^). Overskrider denne tid 2,5 timer, angis den etter denne tid fuktede flate i prosent, (f.eks. 2,5 timer/80^). Den for fastleggelse av penetreringsverdien anvendte filterplate er et grovklarsiktfil ter, slik det anvendes i kunstharpiksindustrien. Etter fremstillerens angivelser (firam Seitz Filterwerke D-6550 Bad Kreuznach) består filterplaten av cellulose og krysotilfibre. Platen har en filtereffekt -4 (definert ved hjelp av en 10-delt skala: Verdi "1" skillegrense ca. 10 pm, verdi "10" skillegrense ca. 0,1 pm). Filtreringshastigheten angis med ca. The penetration value is the time required by an 18# aqueous solution of a potassium salt of the adduct to completely wet a specified filter plate (see below) of size 50 x 100 mm, standing on the narrow side in a 250 cm<5>beaker, the amount of the impregnation solution in the beaker being 25 g (e.g. 60 min/100^). If this time exceeds 2.5 hours, the wetted surface after this time is indicated in percentage, (eg 2.5 hours/80^). The filter plate used to determine the penetration value is a coarse clear filter, as is used in the synthetic resin industry. According to the manufacturer's instructions (from Seitz Filterwerke D-6550 Bad Kreuznach), the filter plate consists of cellulose and chrysotile fibres. The plate has a filter effect of -4 (defined using a 10-part scale: Value "1" separation limit approx. 10 pm, value "10" separation limit approx. 0.1 pm). The filtration speed is indicated by approx.

Som hjelpeoppløsningsmiddel kan saltoppløsningen inneholde inntil maksimalt 20$ av en glykoleter, fortrinnsvis dietylenglykolmonoetyleter. 300 1 m~<2>min-<1>for water at 20° C and A p = 0.2 bar. As auxiliary solvent, the salt solution can contain up to a maximum of 20% of a glycol ether, preferably diethylene glycol monoethyl ether.
Blandingen av adduktsaltoppløsninger med forskjellige penetrasjonsverdi bevirker en ved den forskjellige inntreng-ingsdybde betinget fraksjonering og dermed en jevn fordelilng av impregneringen. Den skadedyrbek j empelsesvirkning , likeledes fuktighetsreguleringen, er dermed så vel gitt i nærheten av overflaten som også betinget ved høy inntreng-ingsdybde av den annen komponent, jevnt fordelt over et stort område i treets indre. Produktene krever bare små mengder av hj elpeoppløsningsmidler og har hverken ved påføring eller senesre noen uheldig lukt. The mixture of adduct salt solutions with different penetration values results in a fractionation dependent on the different penetration depth and thus an even distribution of the impregnation. The pest control effect, as well as the humidity regulation, is thus both provided close to the surface and also conditioned by a high penetration depth of the second component, evenly distributed over a large area in the wood's interior. The products only require small amounts of co-solvents and have no unpleasant odor either during application or afterwards.
Penetrasjonsverdien kan bare i begrenset omfang bringes i forbindelse med viskositeten av det til adduktsaltet til-grunnliggende addukt, således at det i flertall av tilfellene ikke er mulig med noen forutsigelse av penetrasjonsevnen. Som adduktsalter anvendes for produktene ifølge oppfinnelsen partielt eller fullstendig med baser nøytraliserte tillagr-ingsforbindelser av maleinsyreanhydrid (MSA) til tørkende oljer og/eller til slike oljeoppbyggende umettede fettssyrer og/eller til hydroksylfrie syntetisk fremstilte estere av disse fettsyrer med di- eller polyoler. Anhydridstrukturen åpnes før nøytraliseringen ved omsetning med vann og/eller monoalkoholer med 1 til 10 C-atomer. The penetration value can only be linked to a limited extent with the viscosity of the basic adduct of the adduct salt, so that in the majority of cases no prediction of the penetration ability is possible. As adduct salts are used for the products according to the invention partially or completely neutralized with bases preparation compounds of maleic anhydride (MSA) for drying oils and/or for such oil-building unsaturated fatty acids and/or for hydroxyl-free synthetically produced esters of these fatty acids with di- or polyols. The anhydride structure is opened before neutralization by reaction with water and/or monoalcohols with 1 to 10 C atoms.
Til addusering anvendes naturlige tørkende oljer samt av naturlige oljer ved polymeri sasjon eller dehydrati sering bl.a. dannede produkter med et jodtall på minst 100. Fortrinnsvis inneholder disse oljer, som linolje, soyaolje eller dehydratisert rizinusolje i det vesentlige fettsyrer med isolerte dobbeltbindinger. Konjuenolje, som treolje bl.a. kan være inneholdt i underordnet grad. Konjuenoljer kan ved fremstillingen av adduktene tjene til oppfanging av rstene av ikke-addusert maleinsyreanhydrid. For adduction, natural drying oils are used as well as natural oils during polymerization or dehydration, e.g. formed products with an iodine number of at least 100. Preferably, these oils, such as linseed oil, soya oil or dehydrated castor oil, essentially contain fatty acids with isolated double bonds. Conjuen oil, such as wood oil i.a. may be contained to a lesser extent. In the preparation of the adducts, conjuen oils can serve to capture the remains of non-adducted maleic anhydride.
De i disse oljer inneholdte umettede fettsyrer eller deres blandinger kan likeledes anvendes til addusering. Med disse utgangsstoffer fåes spesielt lavviskose addukter. Videre kan det også anvendes hydroksylfrie estere av disse syrer med dioler, som etylenglykol og dets homologer resp. de eter-gruppeholdige polymere av disse glykoler og med polyoler, som trimetyloletan eller -propan. Esterene må for en uklanderlig addusering av maleinsyreanhydridet være best mulig fri for uforestrede hydroksylgrupper. The unsaturated fatty acids contained in these oils or their mixtures can also be used for adduction. With these starting materials, particularly low-viscosity adducts are obtained. Furthermore, hydroxyl-free esters of these acids with diols, such as ethylene glycol and its homologues or the ether-group-containing polymers of these glycols and with polyols, such as trimethylolethane or -propane. For an impeccable adduction of the maleic anhydride, the esters must be as free as possible of unesterified hydroxyl groups.
Mengden av maleinsyreanhydrid i adduktene utgjør mellom 5 og 30 vekt-#, idet ved fettsyreestere ligger området fortrinnsvis mellom 10 og 25 vekt-#, fettsyrer mellom 20 og 30 vekt-56. The amount of maleic anhydride in the adducts is between 5 and 30 wt-#, with fatty acid esters preferably between 10 and 25 wt-#, fatty acids between 20 and 30 wt-56.
Anhydridstrukturene av adduktene hydrolyseres med vann, eventuelt i nærvær av katalysatorer, f.eks. et tertiært amin. Fortrinnsvis foregår åpningen av anhydridstrukturen ved halvesterdannelse med monoalkoholer med 1 til 10 karbonatomer. Spesielt fordelaktig er for foreliggende oppfinn-else addukthal vestere, som som monoalkoholkomponenter har glykolmonoeter, diglykolmonoeter eller triglykolmonoeter. The anhydride structures of the adducts are hydrolysed with water, possibly in the presence of catalysts, e.g. a tertiary amine. Preferably, the opening of the anhydride structure takes place by half-ester formation with monoalcohols with 1 to 10 carbon atoms. Particularly advantageous for the present invention are adduct esters which have glycol monoether, diglycol monoether or triglycol monoether as monoalcohol components.
De forskjellige egenskaper av adduktforbindelsene kan oppnås ved tilsvarende valg (a) av olje- resp. fettsyrekomponentene, (b) av maleinsyreanhydridmengden og (c) ved typen av åpningen av anhydridringen. The different properties of the adduct compounds can be achieved by corresponding choice (a) of oil or the fatty acid components, (b) by the amount of maleic anhydride and (c) by the type of opening of the anhydride ring.
For kombinasjonen ifølge oppfinnelsen anvendes så vel blandinger av høymaleiniserte fettsyreestere (20 til 25 For the combination according to the invention, mixtures of highly maleinated fatty acid esters (20 to 25
vekt-# maleinsyreanhydrid) med lavmaleiniserte fettsyreestere (10 til 12,5 vekt-# maleinsyreanhydrid) eller tilsvarende blandinger av maleiniserte fettsyrer (25 til 30 vekt-# resp. 20 til 25 vekt-# maleinsyreanhydrid), som også blandinger av lavmaleinisesrte fettsyreestere og høymaleiniserte fettsyrer. wt-# maleic anhydride) with low-maleinized fatty acid esters (10 to 12.5 wt-# maleic anhydride) or corresponding mixtures of maleinized fatty acids (25 to 30 wt-# resp. 20 to 25 wt-# maleic anhydride), as well as mixtures of low-maleinized fatty acid esters and highly maleated fatty acids.
For oppnåelse av vannoppløseligheten nøytraliseres adduktforbindelsene alene eller allerede i blanding partielt eller fullstendig under saltdannelse med uorganiske eller organiske baser, som alkalihydroksyder, ammoniakk eller organiske aminer, fortrinnsvis tertiære eller sekundære aminer resp. alkanolaminer. Nøytraliseringsgraden er gitt ved stabiliten av den fortynnede vandige oppløsning. To achieve the water solubility, the adduct compounds are neutralized alone or already in mixture partially or completely during salt formation with inorganic or organic bases, such as alkali hydroxides, ammonia or organic amines, preferably tertiary or secondary amines resp. alkanolamines. The degree of neutralization is given by the stability of the diluted aqueous solution.
Blandingen av komponentene kan varieres innen vide grenser. Fortrinnsvis skal kombinasjonen ligge i en ramme at hverken den godt penetrerende del alene eller den dårlig penetrerende alene utgjør mindre enn 30 vekt-# (referert til fastharpiks). Spesielt foretrukket er blandinger, hvori den godt penetrerende del utgjør 50 til 70 vekt-#. The mixture of the components can be varied within wide limits. Preferably, the combination should be in a range that neither the well-penetrating part alone nor the poorly penetrating part alone amounts to less than 30 wt-# (referred to solid resin). Particularly preferred are mixtures in which the well-penetrating part amounts to 50 to 70% by weight.
Impregneringene inneholder ved siden av bærermaterialet, vannet og eventuelt hjelpeoppløsningsmidler, de vanlige trebeskyttelsesvirksomme stoffer, samt eventuelt pigmenter og hjelpestoffer, som hudhlndrlngsmidler, stabilisatorer, fuktemidler og lignende. Disse tilsetningsmidler samt formuleringen av impregneringer for forskjellige tre og trematerialer er kjent for fagfolk eller kan uttas av den angjeldende litteratur. Impregneringene overstrykes vanlig-vis etter tilstrekkelig tørketid med en trelasur. In addition to the carrier material, the impregnations contain the water and possibly auxiliary solvents, the usual substances active in wood protection, as well as possibly pigments and auxiliary substances, such as skin care agents, stabilizers, wetting agents and the like. These additives as well as the formulation of impregnations for various wood and wood materials are known to those skilled in the art or can be taken from the relevant literature. The impregnations are usually painted over after sufficient drying time with a wood stain.
