Description
Foreliggende oppfinnelse vedrører en fremgangsmåte for beskyt-telse av trevirke mot råtesopp og skadeinsekter ved at trevir- The present invention relates to a method for protecting wood against rot fungi and harmful insects by
ket impregneres ved overtrykk med et råte- og insektsbeskyttende middel som er oppløst i en ikke-brennbar organisk væske med kokepunkt 30 - 100°C såsom et fler-halogenert hydrokarbon, fortrinnsvis et med klor substituert hydrokarbon, hvoretter overskudd av oppløsningen fjernes og trevirket oppvarmes ved normaltrykk for avdampning av oppløsningsmidlet. the wood is impregnated by overpressure with a rot and insect protection agent that is dissolved in a non-flammable organic liquid with a boiling point of 30 - 100°C such as a multi-halogen hydrocarbon, preferably a chlorine-substituted hydrocarbon, after which the excess of the solution is removed and the wood is heated at normal pressure to evaporate the solvent.
Det er tidligere kjent å impregnere trevirket ved nedsenkning It is previously known to impregnate the wood by immersion
av dette i en i et trykkar forefinnende behandlingsoppi6sning, of this in a treatment notice contained in a printed vessel,
som inneholder et modifiseringsmiddel for trevirke, idet modifiseringsmidlet er opplost i et halogenert hydrokarbon som koker i området 35 - loO°C, hvoretter overskuddsmengden av behandlings-opplosningen fjernes og det impregnerte trevirket oppvarmes ved hjelp av vanndamp eller damp av det halogeniserte hydrokarbon-opplosningsmiddel for torking av trevirket. which contains a modifier for wood, the modifier being dissolved in a halogenated hydrocarbon which boils in the range of 35 - 100°C, after which the excess amount of the treatment solution is removed and the impregnated wood is heated by means of water vapor or steam of the halogenated hydrocarbon solvent for drying the wood.
Ved den kjente fremgangsmåte må impregneringsopplosningsmidlet renses fra tid til annen, hvilket utfores ved at dette blandes med mineralolje, hvoretter opplosningsmidlet destilleres fra oljen og modifiseringsmidlet, som blir tilbake i oljen. In the known method, the impregnation solvent must be cleaned from time to time, which is done by mixing it with mineral oil, after which the solvent is distilled from the oil and the modifier, which remains in the oil.

ling av treet og deformering av dette og hvis man anvender damp fra det oppvarmede halogeniserte hydrokarbon er det vanskelig å beherske gjenvinningen av opplosningsmidlet, slik at dette ikke sprer seg i arbeidsrommet. Også fremgangsmåtens varmeokonomi er dårlig når man er tvunget til å anvende damp for oppvarmning ling of the wood and deforming it, and if you use steam from the heated halogenated hydrocarbon, it is difficult to control the recovery of the solvent, so that it does not spread in the working room. The heat economy of the method is also poor when one is forced to use steam for heating
av trevirket og ytterligere at opplosningsmidlet må destilleres separat. of the wood and further that the solvent must be distilled separately.
Man kjenner også en fremgangsmåte der trevirket torkes etter impregnering ved hjelp av en hbytkokende væske, som ikke blander seg med opplosningsmidlet, og ved et undertrykk og en sådan temperatur at opplosningsmidlet avdestillerer, fortrinnsvis ved 60 - 90°c, hvoretter torkemediet fjernes fra behandlingskammeret. Ifolge denne fremgangsmåte må man anvende et stort undertrykk A method is also known in which the wood is dried after impregnation with the help of a fast-boiling liquid, which does not mix with the solvent, and at a negative pressure and such a temperature that the solvent distills off, preferably at 60 - 90°c, after which the drying medium is removed from the treatment chamber. According to this method, a large negative pressure must be applied
for avdestillering av opplosningsmidlet og for å fjerne dette tilstrekkelig hurtig fra trevirket, samt ved en så lav temperatur at trevirket ikke skades. to distill off the solvent and to remove this sufficiently quickly from the wood, and at such a low temperature that the wood is not damaged.
Det er nå overraskende funnet at opplosningen kan, hvis trevirket er impregnert med et lettflyktig beskyttelsesmiddel opplost i et organisk oppldsningsmiddel lett fjernes ved normaltrykk fra trevirket ved at dette bringes i kontakt med en hbytkokende torke-olje som blander seg med opplosningsmidlet. Det er nemlig fast-slått at opplosningsmidlet, i motsetning til den generelle opp-fatning, raskt avgår fra trevirket hvis det som oppvarmningsmedium anvendes en olje hvori opplosningsmidlet forst opploser seg og deretter avdestilleres separat fra oppvarmningsmediet. It has now surprisingly been found that, if the wood is impregnated with a volatile protective agent dissolved in an organic solvent, the solution can easily be removed at normal pressure from the wood by bringing it into contact with a fast-boiling drying oil that mixes with the solvent. It has been established that, contrary to general opinion, the solvent quickly leaves the wood if an oil is used as the heating medium in which the solvent first dissolves and is then distilled off separately from the heating medium.
Ved siden av en raskere avdestillering uten anvendelse av undertrykk oppnår man ved fremgangsmåten ifolge oppfinnelsen, hvis kjennetegn fremgår av krav 1, den ytterligere fordel at opples-ningen av det ikke-brennbare opplbsningsmiddel i den varme tbrkeoljen i vesentlig grad minsker oljens brannfarlighet. Som folge av at opplosningsmidlet opploser seg i tbrkeoljen kan avdestil-leringen også utfores delvis eller helt i et andre separasjons-trinn og ved hbyere temperatur enn normalt, uten at den hoye temperaturen vil beskadige trevirket. Ytterligere kan også im-pregneringskapasiteten forbkes. In addition to faster distillation without the use of negative pressure, the method according to the invention, the characteristics of which appear in claim 1, has the further advantage that the removal of the non-flammable solvent in the hot drinking oil substantially reduces the oil's flammability. As a result of the solvent dissolving in the wood oil, the distillation can also be carried out partially or completely in a second separation step and at a higher temperature than normal, without the high temperature damaging the wood. Furthermore, the impregnation capacity can also be increased.
Fremgangsmåten ifolge oppfinnelsen for impregnering av trevirket adskiller seg fra tidligere kjente fremgangsmåter og man unngår de ulemper som disse er beheftet med, ved at fremgangsmåten fra et praktisk synspunkt er ufarlig og forårsaker ikke miljbfarer, eksempelvis p.g.a. opplbsningsmidlets avdunstning, og ytter- The method according to the invention for impregnating the wood differs from previously known methods and the disadvantages associated with these are avoided, in that the method is from a practical point of view harmless and does not cause environmental hazards, for example due to the evaporation of the solvent, and
ligere innspares kostbar varmeenergi. expensive heat energy is saved.
Ved fremgangsmåten ifolge oppfinnelsen impregneres trevirket In the method according to the invention, the wood is impregnated
i et begrenset, trykkbestandig rom med et overtrykk (2 - 12 kp/cm 2) in a confined, pressure-resistant room with an excess pressure (2 - 12 kp/cm 2 )

karbon. Som beskyttelsesmiddel kan anvendes kobberftalat, kobber-naftenat, tetraklorfenol, heptaklor, lindan eller andre kjente råte- og insektsbeskyttelsesmidler. Som opplosningsmiddel kan anvendes metylenklorid, trikloretylen, karbontetraklorid eller andre lavtkokende (kp. 30 - 100°C), ikke-brennbare organiske væsker. carbon. As a protective agent, copper phthalate, copper naphthenate, tetrachlorophenol, heptachlor, lindane or other known rot and insect protection agents can be used. Methylene chloride, trichlorethylene, carbon tetrachloride or other low-boiling (bp. 30 - 100°C), non-flammable organic liquids can be used as solvents.
Opplosningen kan bringes til å trenge dypt inn i trevirket enda The solution can be made to penetrate deep into the wood even more

The solvent that is in the wood departs from it relatively completely (over 90% recovery): and at a distillation time of approx. 1 hour when the distillation temperature is in the range 80 - 140°C.

Ved fremgangsmåten ifolge oppfinnelsen kan også dette trinn gjennomfores overraskende raskt, på kun noen få minutter, ved at det varme trevirket fjernes fra trykkammeret og umiddelbart nedsenkes i en ved romtemperatur behandlingsopplbsning, hvorved torkeoljen på treets overflate overraskende suges fullstendig inn i trevirket. Hvis det som behandlingsoppiosning anvendes en akrylatlateksemulsjon, i hvilken det ytterligere kan inn-blandes forskjellige typer fargeemner, kan også denne bringes til å suges inn i trevirkets overflate utenpå torkeoljen, hvor- With the method according to the invention, this step can also be carried out surprisingly quickly, in just a few minutes, by removing the hot wood from the pressure chamber and immediately immersing it in a treatment solution at room temperature, whereby the drying oil on the surface of the wood is surprisingly completely absorbed into the wood. If an acrylate latex emulsion is used as a treatment solution, in which different types of dyes can also be mixed, this can also be caused to be absorbed into the surface of the wood outside the drying oil, where
