Description

DK 151854BDK 151854B

Opfindelsen angår anvendelse af et vandbindende middel til konservering af træ.The invention relates to the use of a water-binding agent for preserving wood.

Det er ofte ønskeligt at formindske vandindholdet i træ, hvad enten dette foreligger som bygningsdele el-5 ler i anden tildannet form, eller som kun delvis forarbejdet tømmer.It is often desirable to reduce the water content of wood, whether as building parts or in other molded form, or as only partially processed timber.

Formålet med en sådan nedbringelse af fugtigheds-indholdet kan være at bringe fugtighedsindholdet ned på så lave værdier, at træet er mindre udsat for angreb af 10 ødelæggende mikroorganismer, og/eller at gøre træet egnet til at modtage en beskyttende imprægnering eller overfladebehandling.The purpose of such a reduction in the moisture content may be to bring the moisture content down to such low values that the tree is less susceptible to attack by 10 destructive microorganisms, and / or to render the tree suitable for receiving a protective impregnation or surface treatment.

Der har været foreslået forskellige metoder til at nedbringe træs vandindhold.Various methods have been proposed to reduce the water content of wood.

15 Således kendes fra DE-AS 2812697 en fremgangsmåde til træbehandling, ved hvilken et vandskyende middel i forbindelse med et vandfortrængende middel anbringes i hulrum i træet,, hvorefter disse hulrum lukkes tæt.Thus, from DE-AS 2812697 a method of wood treatment is known, in which a water repellent in connection with a water displacer is placed in cavities in the wood, after which these cavities are closed tightly.

Denne kendte fremgangsmåde har imidlertid den 20 ulempe, at diffusionen af vand i træet og dermed vandets fortrængning sker meget langsomt, og ved træ, der er forsynet med en belægning, f.eks. i form af en lakering eller plastbelægning, er vandets udtræden fra træet kraftigt hæmmet og under visse omstændigheder helt udeluk-25 ket.However, this known method has the disadvantage that the diffusion of water into the wood and thus the displacement of the water takes place very slowly, and in wood that is provided with a coating, e.g. in the form of a lacquer or plastic coating, the water's exit from the tree is severely hampered and, in certain circumstances, completely excluded.

I tysk patent nr.885.177 foreslås det, før imprægnering af bygningsdele med kemiske giftstoffer, at nedbringe bygningsdelenes fugtighed ved opvarmning eller ved anvendelse af adsorberende stoffer, som bringes i 30 kontakt med bygningsdelenes overflade eller ved hjælp af borehuller indføres i det indre af disse. En tilsvarende metode kan anvendes til at nedbringe fugtighedsind-holdet efter tilførslen af det vandopløselige giftstof med henblik på at fjerne opløsningsmidlet fra dette.German Patent No. 885177 proposes, before impregnating building components with chemical toxins, to reduce the moisture of the building parts by heating or by using adsorbents which are brought into contact with the surface of the building parts or by means of boreholes introduced into the interior thereof. A similar method can be used to reduce the moisture content after the application of the water-soluble toxin to remove the solvent from it.

35 Patentskriftet oplyser ikke, hvilke stoffer man har tænkt at anvende som "adsorberende" stof.35 The patent does not specify which substances are intended to be used as "adsorbent" substances.

Fra tysk patentskrift nr. 29 324 er det kendt at tørre træ ved at bringe det i kontakt med fugtsugende 2From German Patent Specification No. 29,324, it is known to dry wood by contacting it with a vacuum cleaner 2

DK 151854BDK 151854B

materialer såsom kogesalt (natriumchlorid), calciumchlo-rid eller blandinger af disse materialer.materials such as boiling salt (sodium chloride), calcium chloride or mixtures of these materials.

Anvendelse af sådanne uorganiske salte til det pågældende formål medfører imidlertid visse ulemper, da 5 en vis del af saltene vil optages i træet og sammen med den resterende vandmængde i dette eller sammen med vand, som senere måtte blive opsuget af træet, danner en elektrolyt. Dette medfører dels, at træets evne til at fastholde en lak- eller malingfilm forringes, idet tendensen 10 til blæredannelse øges, dels at metaldele såsom søm, skruer, beslag og zinkplader, som kommer i kontakt med det behandlede træ, udsættes for en kraftigere korrosion end tilfældet ville være, hvis de pågældende salte ikke var til stede.However, the use of such inorganic salts for that purpose causes certain disadvantages, since a certain part of the salts will be absorbed into the wood and together with the remaining amount of water therein, or together with water which may later be absorbed by the wood, form an electrolyte. This causes, in part, the ability of the wood to retain a varnish or paint film, as the tendency for blistering increases, and secondly, metal parts such as nails, screws, fittings and zinc sheets that come into contact with the treated wood are subjected to more severe corrosion. than would be the case if the salts in question were not present.

15 Det har nu vist sig, at de ovennævnte ulemper und gås ved, ifølge opfindelsen, at anvende en orthocarboxyl-syreester til formindskelse af træfugtighedsindholdet.It has now been found that the above disadvantages are avoided by using, according to the invention, an orthocarboxylic acid ester to reduce the moisture content of wood.

Særligt gode resultater er opnået ved at anvende triethylorthoformiat til formindskelse af træfugtigheds-20 indholdet.Particularly good results have been obtained by using triethyl orthoformate to reduce the wood moisture content.

TLI overflødiggørelse af efterfølgende imprægnering af træværket med træbeskyttelsesmidler er det hensigtsmæssigt, at det vandbindende middel anvendes i kombination med trækonserverende fungicider, baktericider og/eller 25 insekticider.TLI redundancy of subsequent impregnation of the woodwork with wood preservatives, it is convenient that the water-binding agent be used in combination with wood preservative fungicides, bactericides and / or insecticides.

Ved sanering af ældre bygninger foreligger ofte det problem, at vinduesrammer i deres nederste trediedel har forhøjet fugtighedsindhold, hvilket i samvirke med mikroorganismer med tiden fører til en fuldstændig øde-30 læggelse af træet.When renovating older buildings, there is often the problem that window frames in their lower thirds have increased moisture content, which, in conjunction with microorganisms over time, leads to complete destruction of the tree.

Der er behov for en fremgangsmåde, der i sådanne tilfælde muliggør en hurtig nedsættelse af træets fugtigheds indhold, også i de tilfælde, hvor træet et malet eller lakeret.There is a need for a method which in such cases allows a rapid reduction in the moisture content of the wood, even in cases where the wood is painted or varnished.

i 35 Dette behov opfyldes af en fremgangsmåde, ved hvilken et vandbindende middel i flydende eller pastaagtig form på i sig selv kendt måde anbringes i udsparinger eller hulrum i træet, hvorefter disse hulrum luk- 3This need is met by a method in which a liquid or paste-like agent, in a manner known per se, is placed in recesses or cavities in the wood, after which these cavities are closed.

kes tæt, idet fremgangsmåden ifølge opfindelsen er ejendommelig ved, at der som vandbindende middel anbringes en opløsning af en orthocarboxylsyreester i et organisk opløsningsmiddel i hulrummene.The process according to the invention is characterized in that, as a water-binding agent, a solution of an orthocarboxylic acid ester in an organic solvent is placed in the cavities.

5 Egnede orthocarboxylsyreestere er f.eks. trime- thylorthoformiat, trimethylorthoeddikesyreester, tri-ethylorthoeddikesyreester og tilsvarende estere af ortho-propionsyre. Særlig foretrukken er dog en opløsning af triethylorthoformiat, der fordelagtigt har en koncentra-10 tion på 10 til 40 vægts.Suitable orthocarboxylic acid esters are e.g. trimethyl orthoformate, trimethyl ortho acetic ester, tri ethyl ortho acetic ester and corresponding esters of ortho-propionic acid. Particularly preferred, however, is a solution of triethyl orthoformate which advantageously has a concentration of 10 to 40 wt.

En særlig god konservering af træ opnås ved, at opløsningen udover det vandbindende middel indeholder fungicider, baktericider og/eller insekticider. Opløsningen kan f.eks. indeholde tributyltinoxid i en 15 koncentration fra 1 til 10 vægt% og/eller N-dimethyl-N'-phenyl-N'-(fluordichlormethyl)-thiosulfamid i en koncentration fra 0,5 til 40 vægt%.A particularly good preservation of wood is achieved by the fact that in addition to the water-binding agent the solution contains fungicides, bactericides and / or insecticides. The solution may e.g. contain tributyltin oxide at a concentration of 1 to 10% by weight and / or N-dimethyl-N'-phenyl-N '- (fluorodichloromethyl) thiosulfamide at a concentration of 0.5 to 40% by weight.

Til forbedring af den konserverende virkning kan opløsningen indeholde en naturlig eller syntetisk 20 voksart i en koncentration fra 2 til 20 vægt%. Denne voks forhindrer den yderligere indtrængen af fugtighed i træet og understøtter således det vandbindende middels virkning. Egnet er f.eks. en polyethylenvoks med en gennemsnitlig molekylvægt på ca. 2000. Der kan også an-25 vendes parafiner med et smeltepunktområde omkring ca.To enhance the preservative effect, the solution may contain a natural or synthetic wax species at a concentration of 2 to 20% by weight. This wax prevents the further penetration of moisture into the wood and thus supports the action of the water-binding agent. Suitable for example. a polyethylene wax having an average molecular weight of approx. 2000. Paraffins with a melting point range of about ca.

70°C.70 ° C.

Fremgangsmåden ifølge opfindelsen gennemføres med fordel på den måde, at konserveringsmidlet anbringes i borehuller, der er rettet skråt nedad, hvorefter 30 disse borehuller lukkes med en træfyldmasse. Borehullerne lukkes med fordel med en træfyldmasse, der hærdes med et hærdningsmiddel. Sådanne masser er kendte som "tokomponent træfyldmasser". Efter lukningen af borehullet og hærdning af lukkemassen kan det behandlede sted 35 males, således at konserveringsforanstaltningerne ikke efterlader synlige spor.Advantageously, the method according to the invention is carried out in that the preservative is placed in downwardly directed boreholes, after which these bores are closed with a wood filler. The boreholes are advantageously closed with a wood filler which is cured with a curing agent. Such masses are known as "two-component wood fillers". After closure of the borehole and curing of the closure, the treated site 35 can be painted so that the preservation measures leave no visible traces.

Eksempel 1Example 1

Fugtighedsindholdet i en vinduesramme, der var forsynet med en påstrygningslag bestemtes ved hjælp af 20 et træfugtighedsmåleapparat, hvis måling beror på bestemmelse af den elektriske ledningsevne. Det udgjorde i rammens nederste trediedel ca. 30%. I rammen boredes i en vinkel på 30° med et 8 mm bor ca. 4 cm dybe nedadrettede åbninger. Åbningerne fyldtes ca. 2/3 med 25 en konserveringsopløsning med den i det følgende angivne sammensætning og lukkedes med en træfyldmasse.The moisture content of a window frame provided with an ironing layer was determined by means of a wood moisture meter, the measurement of which depends on the determination of the electrical conductivity. In the lower third of the frame, this amounted to approx. 30%. The frame was drilled at an angle of 30 ° with an 8 mm bore approx. 4 cm deep downwards openings. The openings were filled approx. 2/3 with 25 a preservative solution of the composition given below and closed with a wood filler.

Efter 2 uger bestemtes fugtighedsindholdet påny.After 2 weeks, the moisture content was again determined.

Det var sunket til en værdi på ca. 20%. Ved dette fugtig-hedsindhold er f.eks. skimmelvækst udelukket. Derudover 30 kunne det fastslås, at det behandlede træ var blevet tydeligt fastere, hvilket viste sig ved, at der til ind-trykning af en hård genstand i træet krævedes en større kraft end før.It had sunk to a value of approx. 20%. At this moisture content, e.g. mold growth excluded. In addition, it could be determined that the treated wood had become significantly firmer, as evidenced by the fact that a greater force was required to press a hard object into the tree.
