Description

DESCRIZIONE dell'invenzione industriale dal titolo: DESCRIPTION of the industrial invention entitled:

"Sostanza impregnante‘per legno" "Impregnating substance for wood"

D E S C R I Z I O N E DESCRIPTION

La presente invenzione concerne un mezzo impregnante per legno, che allo stesso tempo é colorante. Essa concerne inoltre un procedimento per la sua produzione. The present invention relates to an impregnating medium for wood, which at the same time is a coloring agent. It also concerns a process for its production.

Mezzi impregnanti per legno sono già noti. Essi servono a proteggere il legno da influenze dannose dell'ambiente ovvero a prolungare la sua durata. In particolare si persegue una protezione contro l'attacco di funghi e "batteri di marcescenza, alghe e animali come insetti. I mezzi impregnanti sono di nor ma sistemi liquidi, che possono anche contenere acqua. Impregnating means for wood are already known. They serve to protect the wood from harmful environmental influences or to extend its service life. In particular, protection against the attack of fungi and rotting bacteria, algae and animals such as insects is pursued. The impregnating media are normally liquid systems, which may also contain water.

Un mezzo di.protezione per legno ideale deve presentare effetto velenoso persistente contro parassiti, non deve tuttavia essere velenoso per uomini e animali domestici. Esso non deve attaccare i metalli, penetrare il più facilmente possibile anche in legno non trattato preventivamente, non deve essere dilavato da pioggia e così via e deve essere il più possibile a buon prezzo. An ideal wood protection medium must have a persistent poisonous effect against parasites, but must not be poisonous to humans and pets. It must not attack metals, penetrate as easily as possible even in previously untreated wood, it must not be washed away by rain and so on and must be as cheap as possible.

Una grande difficoltà rappresenta la penetrazione del mez. zo nel legno. Perciò s'impiegano attualmente procedimenti a pressione in caldaia, nei quali il legno pretrattato in un re cipiente chiuso, contenente mezzo impregnante viene esposto alternativamente a sovrapressioni e depressioni. A great difficulty represents the penetration of the mez. zo in the wood. Therefore, boiler pressure processes are currently used, in which the wood pretreated in a closed vessel containing impregnating medium is alternately exposed to overpressures and depressions.

Questi procedimenti non sono impiegatili su oggetti di legno finiti ed in particolare su articoli di legno nell'edilizia oppure solo in modo molto costoso. I procedimenti di verniciatura, che sono già anche noti, hanno l'inconveniente che gli oggetti di legno anzitutto devono provvisti di un fon do e poi di un'altra mano di vernice superficiale. Vi si aggiunge che il Carbolineum impiegato in precedenza come mezzo impregnante efficace attualmente non può più venire impiegato a causa della sua velenosità These processes are not used on finished wooden objects and in particular on wooden articles in construction or only in a very expensive way. The painting processes, which are also already known, have the drawback that the wooden objects must first be provided with a primer and then with another coat of surface varnish. In addition, the Carbolineum previously used as an effective impregnating medium can no longer be used due to its poisonousness.

La protiematica descritta in quanto precede e gli inconvenienti delle soluzioni attuali nel campo della conservazione del legno sono trattati dettagliatamente nel Chemie-Lexikon di Römpp ad esempio 6. Ediz. 1966, Vol. II, Sp. 2758-2762. The prothhematics described above and the drawbacks of current solutions in the field of wood preservation are dealt with in detail in Römpp's Chemie-Lexikon for example 6. Ediz. 1966, Vol. II, Sp. 2758-2762.

Compito della presente invenzione era la realizzazione di un mezzo impregnante per legno anidro in particolare effica ce come fungicida e alghicida, che possa venire applicato nella pittura, che penetri nel legno meglio dei mezzi noti, ma allo stesso tempo agisca come finish di superficie, cioè che renda non necessaria l'applicazione di una vernice di superficie, vernice o pittura. Inoltre il mezzo deve proteggere meglio il legno dall’azione dell'acqua, luce UV, irradiazione solare e freddo ed essere compatitile con l'ambiente, anche per quanto concerne la produzione. Infine il legno deve poter venire colorato a piacere. The aim of the present invention was to provide an impregnating medium for anhydrous wood in particular effective as a fungicide and algaecide, which can be applied in the paint, which penetrates the wood better than the known means, but at the same time acts as a surface finish, i.e. which makes the application of a surface varnish, varnish or paint unnecessary. In addition, the medium must better protect the wood from the action of water, UV light, solar radiation and cold and be compatible with the environment, also with regard to production. Finally, the wood must be able to be colored as desired.

Il mezzo impregnante per legno secondo la presente inven zione, che soddisfa questi compiti é definito nella rivendica zione indipendente 1. Particolari elaborazioni formano l'oggetto di rivendicazioni dipendenti. The impregnating medium for wood according to the present invention, which fulfills these tasks is defined in independent claim 1. Particular processes form the subject of dependent claims.

Come inoltre venne trovato sorprendentemente, la successione dell'aggiunta dei componenti del mezzo impregnante per legno secondo la presente invenzione é critica in quanto ché per una successione determinata vengono ottenuti i migliori risultati. Perciò la presente invenzione concerne inoltre un procedimento per la preparazione del mezzo impregnante per le gno, che é definito nella seconda rivendicazione indipendente. As was also surprisingly found, the succession of adding the components of the impregnating medium for wood according to the present invention is critical in that the best results are obtained for a determined succession. Therefore, the present invention also relates to a process for the preparation of the impregnating medium for wood, which is defined in the second independent claim.

I singoli componenti del mezzo impregnante per legno devono ora venire identificati in maggior dettaglio. The individual components of the wood impregnating agent must now be identified in more detail.

Componente principale ("Corpo") della fase esente da solventi del mezzo é'una sostanza essiccante chimicamente a base di olio di lino, che normalmente é nota solo per l'impiego per pitture di superficie. Preferibilmente si tratta di un olio di lino modificato da isocianato. Particolarmente adatto é il prodotto Uralac ? 77» che viene fornito come soluzione al 60 % in White Spirit della Ditta DMS Resins. Main component ("Body") of the solvent-free phase of the medium is a chemically drying substance based on linseed oil, which is normally known only for use in surface paints. Preferably it is an isocyanate-modified linseed oil. Particularly suitable is the Uralac product? 77 »which is supplied as a 60% solution in White Spirit by DMS Resins.

Per il miglior indurimento di questo prodotto, che in realtà é essiccante all'aria, il cui indurimento però anche nell'interno del legno deve verificarsi prima, vengono aggiun ti i naftenati di metalli per sé noti, ottoati, linoleati, re sinati e simili. Risultati particolarmente "buoni ha dato una miscela di composti di manganese, calcio e zirconio, che é nuo va e produce un'essiccazione sorprendentemente buona e rapida. Siccativi ben adatti di questo gruppo, cioè i derivati di metalli singoli, vennero ottenuti sotto il nome commerciale Nuodex della Ditta URAI S.p.a., Assago, Italia. For the best hardening of this product, which is actually air-drying, the hardening of which, however, also in the interior of the wood must occur first, the naphthenates of known metals, octoates, linoleates, re sinates and the like are added. . Particularly good results gave a mixture of compounds of manganese, calcium and zirconium, which is new and produces surprisingly good and fast drying. Well suited drying agents of this group, namely single metal derivatives, were obtained under the name Nuodex commercial of URAI S.p.a., Assago, Italy.

Come solvente il mezzo impregnante per legno secondo la presente invenzione contiene - oltre il VJhite Spirit - dello olio di lino modificato - solo composti alifatici contenenti ossigeno. I solventi scelti sembrano essere responsabili per la buona penetrazione del mezzo secondo la presente invenzione nel legno. Ha dato buoni risultati una miscela di un glicolete re inferiore del punto d'ebollizione tra 100 e 150°C con un esteralcool del punto d'ebollizione tra 180 a 260°C. Tali glicoleteri sono ad esempio DOwanol PM della Dow Chemical Company (Propilenglicolraetiletere) nonché etilenglicolmetiletere .e etilenglicoletiletere, Esteralcoli sono ad esempio butildiglicoletere ( "Butilcarbitol"), glicolmonoformiato e -acetato. As a solvent, the impregnating medium for wood according to the present invention contains - in addition to VJhite Spirit - some modified linseed oil - only aliphatic compounds containing oxygen. The solvents selected appear to be responsible for the good penetration of the medium according to the present invention into the wood. A mixture of a glycolether below boiling point between 100 and 150 ° C with an ester alcohol boiling point between 180 and 260 ° C gave good results. Such glycolethers are for example DOwanol PM of the Dow Chemical Company (Propylene glycol methyl ether) as well as ethylene glycol methyl ether and ethylene glycol ethyl ether, Esteralcohols are for example butyl glycol ether ("Butylcarbitol"), glycol monoformate and -acetate.

Ha dato buoni risultati il prodotto TEXANOL della Eastman Chemical Corp. Eastman Chemical Corp's TEXANOL product performed well.

Come sostanza biocida il mezzo impregnante per legno contiene preferibilmente un sulfamidderivato, che é efficace contro funghi, alghe, generi Penicillium, stabile alla luce e non volatile e non disturba l'essiccazione del derivato di olio di lino. S'impiega preferibilmente un N,N-diaril-N'-aril-N'-(trialogenometiltio)-sulfamide. Come colorante s'impiegano nel modo il migliore quelli della gamma Sicoflush (BASF). As a biocidal substance, the impregnating medium for wood preferably contains a sulfonamide derivative, which is effective against fungi, algae, genera Penicillium, light-stable and non-volatile and does not disturb the drying of the linseed oil derivative. An N, N-diaryl-N'-aryl-N '- (trialogenomethylthio) -sulfamide is preferably used. As a dye, those from the Sicoflush range (BASF) are best used.

L'agente impregnante per legno secondo la presente inven zione contiene di norma ma non coattivamente un mezzo di distensione, ad esempio aldossime o chetossime. Ossime adatte sono ad esempio butiraidossima, letiletilchetossima. Ulteriori aggiunte adatte sono additivi reologici come ad esempio Bilica ti a strati modificati organicamente ("Bentone SD-1" della Kronos Titan GmbH, Leverkusen, BRD) nonché altri additivi usua li come agenti bagnanti e disperdenti, sostanze aromatizzanti ecc. The wood impregnating agent according to the present invention normally but not necessarily contains a stress reliever, for example aldoxime or ketoxime. Suitable oximes are, for example, butyraidoxime, letylethylketoxime. Further suitable additives are rheological additives such as organically modified layered bilicates ("Bentone SD-1" from Kronos Titan GmbH, Leverkusen, BRD) as well as other usual additives such as wetting and dispersing agents, flavoring substances, etc.

La composizione di mezzi impregnanti per legno adatti é la seguente, indicata in parti in peso:' The composition of suitable impregnating media for wood is the following, indicated in parts by weight: '

Per l'attuazione del procedimento secondo la presente invenzione s’introduce anzitutto il solvente in un recipiente di miscelazione, si fa affluire la soluzione dell'olio di lino modificato e si aggiungoni i siccativi e il biocida. Delle aggiunte facoltative l'agente antipelle viene aggiunto subito dopo i siccativi e l'additivo di reologia alla fine. Ow iamen te nella preparazione si rimescola continuamente. Si opera nel modo il migliore a normale temperatura ambiente; una cari ca di circa 100 kg e approntata in circa 20 a 30 minuti. To implement the process according to the present invention, the solvent is first introduced into a mixing vessel, the modified linseed oil solution is poured in and the siccatives and biocide are added. Of the optional additions the anti-skin agent is added immediately after the siccatives and the rheology additive at the end. Ow iamen te in the preparation it mixes continuously. It works best at normal room temperature; a load of about 100 kg and ready in about 20 to 30 minutes.

Il mezzo impregnante si distingue ancora per elevata immagazz inabilità, in generale circa 8 a 12 mesi. The impregnating medium still stands out for its high storability, generally around 8 to 12 months.

Per l’applicazione si spalma o spruzza la superficie del legno pulita meccanicamente con il mezzo liquido, si fa essic care ad esempio 24 ore e si provvede la superficie con una se conda mano di vernice dello stesso mezzo. Solo molto raramente e necessaria una terza mano di vernice. Il legno é ora impregnato in modo conservante e possiede inoltre una superficie colorata, ad esempio noce, larice, mogano e così via, senza che sia necessaria un'ulteriore mano di pittura come mordente eco. For the application, the mechanically cleaned surface of the wood is spread or sprayed with the liquid medium, it is dried for example 24 hours and the surface is provided with a second coat of paint of the same medium. Only very rarely is a third coat of paint needed. The wood is now conservatively impregnated and also has a colored surface, for example walnut, larch, mahogany and so on, without the need for an additional coat of paint as an eco mordant.

Gli Esempi devono illustrare la presente invenzione in maggior dettaglio. The Examples are to illustrate the present invention in more detail.
