DESCRIZIONE dell'invenzione industriale dal titolo: DESCRIPTION of the industrial invention entitled:
"Mezzo impregnante per legno con vernice translucida per pitture interne" "Impregnating medium for wood with translucent varnish for interior paints"
D E 5 C R I Z I O N E D E 5 C R I Z I O N E
La presente invenzione concerne un mezzo impregnante contenente acqua con vernice trasparente per legno, che é pre visto per pitture interne, ed un procedimento per la sua produzione. The present invention relates to an impregnating medium containing water with transparent varnish for wood, which is intended for interior paints, and to a process for its production.
Vernici trasparenti per legno sono notoriamente colori e pitture che forniscono un rivestimento trasparente o almeno translucido della superficie del legno, che non lascia ricono scere la venatura del legno. Quivi le vernici trasparenti pos sono anche essere coloranti. Per l'inverniciatura trasparente con vernici trasparenti contenenti colorante occorrono pigmen ti particolari, trasparenti o translucidi, nel caso non venga no impiegati coloranti solubili, che in pitture esterne di norma ma non sono sufficientemente stabili alla luce. Il fondo sul quale la vernice trasparente viene applicata, deve quin di non essere coperto, bensì al massimo apparire in un altro tono di colore che il fondo originario Clear wood varnishes are known colors and paints that provide a clear or at least translucent coating of the wood surface, which does not allow the wood grain to be recognized. Here clear paints can also be dyes. For transparent painting with transparent paints containing dye, special pigments are required, transparent or translucent, if soluble dyes are not used, which in external paints are usually not sufficiently stable to light. The background on which the transparent varnish is applied must therefore not be covered, but at most appear in a different tone of color than the original background.
Vernici trasparenti per legno sono già note. Queste vernici trasparenti note contengono un pigmento per vernice trasparente, acqua ed un legante filmogeno polimero, che di norma é presente come dispersione di polimero. Esse hanno tuttavia l’inconveniente, che il legno sottostante non viene suffi cientemente conservato, poiché si persegue finora una permanen za il più possibile completa della vernice trasparente sulla superficie. Per la conservazione sufficiente del legno, che é quasi sempre necessaria, era perciò necessario, impregnarlo con un mezzo conservante; tali mezzi impregnanti sono d'altra parte finora del pari diventati noti. Transparent varnishes for wood are already known. These known clear coatings contain a clear coat pigment, water and a film-forming polymer binder, which is normally present as a polymer dispersion. However, they have the drawback, that the underlying wood is not sufficiently preserved, since so far a permanence as complete as possible of the transparent varnish on the surface has been pursued. For the sufficient conservation of the wood, which is almost always necessary, it was therefore necessary to impregnate it with a preservative; on the other hand, such impregnating means have so far also become known.
Compito della presente invenzione era lo sviluppo di una vernice trasparente per legno per l'impiego per pitture interne, che renda non necessario uno speciale pretrattamento conservante del legno e che penetri più facilmente nell’interno del legno che le vernici trasparenti finora note, per conservarlo ivi allo stesso tempo. In tal modo la pittura del legno dovreb he venire semplificata e resa più economica. Uno scopo era di impregnare il legno in solo due fasi di lavoro con lo stesso prodotto in primo luogo durevolmente ed efficacemente ed in secondo luogo rendere la sua superficie resistente contro effetti esterni, di proteggerlo dal soloe, raggi UV e freddo e conferirgli un aspetto gradevole. The aim of the present invention was the development of a transparent varnish for wood for use in interior paints, which makes a special preservative pre-treatment of the wood unnecessary and which penetrates more easily into the interior of the wood than the clear varnishes known up to now, in order to preserve it. therein at the same time. In this way wood painting should be simplified and made cheaper. One purpose was to impregnate the wood in only two working phases with the same product, firstly durably and effectively and secondly to make its surface resistant against external effects, to protect it from the sun, UV rays and cold and to give it a pleasant appearance. .
In pitture interne si verifica ancora un ulteriore problema, cioè quello dell'essiccazione della preparazione di . vernice trasparente impregnante. Se essa essicca troppo rapidamente, risulta una pellicola, che presenta almeno però una superficie non piana, nervature di ritiro, ruvida. Se essa essicca troppo lentamente, occorre attendere troppo a .lungo per una seconda mano di pittura, e l'equilibrio tra componenti che devono penetrare nel legno, e quelli che piuttosto devono rimanere alla superficie, si sposta in modo incontrollabile. In interior paints there is still a further problem, namely that of the drying of the preparation of. transparent impregnating varnish. If it dries too quickly, a film results, which however has at least a non-flat surface, shrinkage ribs, rough. If it dries too slowly, one has to wait too long for a second coat of paint, and the balance between components that must penetrate the wood, and those that rather must remain on the surface, shifts uncontrollably.
I compiti vengono risolti dal mezzo impregnante per legno secondo la presente invenzione con vernice trasparente per l'im piego per pitture interne, che é definito nella prima rivendi— cazione indipendente. Forme d'attuazione particolari formano l'oggetto di rivendicazioni dipendenti. The tasks are solved by the wood impregnating medium according to the present invention with clear coat for use in interior paints, which is defined in the first independent claim. Particular forms of implementation form the subject of dependent claims.
Come é evidente dalle definizioni delle rivendicazioni, riesce secondo la presente invenzione a riunire un mezzo impregnante per legno conservante con una vernice trasparente per legno. As is evident from the definitions of the claims, according to the present invention it succeeds in combining an impregnating medium for preserving wood with a transparent varnish for wood.
Secondo la presente invenzione il mezzo impregnante contiene tre tipi di liquidi ovvero solventi, cioè acqua, almeno due solventi esenti da idrocarburi,alifatici miscibili con acqua almeno parzialmente, dei quali uno é un glicol ed un altro un regolatore di evaporazione. In tal modo si consegue che il mezzo conservante per il legno può penetrare in questo ultimo ovvero viene introdotto, mentre il legante ed i pigmen ti della vernice trasparente rimangono specialmente alla superficie, e che le condizioni d'essiccazione della pittura vengono regolate. Il mezzo impregnante per legno agisce quin di allo stesso tempo come biocida, impregnazione conservante e come pittura di superficie di inverniciatura trasparente e di protezione According to the present invention, the impregnating medium contains three types of liquids or solvents, i.e. water, at least two hydrocarbon-free, aliphatic solvents miscible with water at least partially, one of which is a glycol and the other an evaporation regulator. In this way it follows that the preservative medium for the wood can penetrate into the latter or is introduced, while the binder and pigments of the transparent varnish remain especially on the surface, and that the drying conditions of the paint are regulated. The impregnating medium for wood therefore acts at the same time as a biocide, preservative impregnation and as a surface paint for transparent varnishing and protection.
Nella preparazione del mezzo impregnante secondo la presente invenzione la successione di aggiunta dei singoli compo nenti é critica in quanto che per una determinata successione vengono conseguiti i migliori risultati, in particolare per quanto riguarda le caratteristiche di elaborazione del mezzo e la qualità dei rivestimenti. La presente invenzione concerne perciò inoltre un procedimento per la preparazione del mezzo im pregnante definito in quanto precede con vernice trasparente per pitture interne per legno, che é definito nella seconda ri vendicazione indipendente. In the preparation of the impregnating medium according to the present invention, the sequence of addition of the individual components is critical in that the best results are achieved for a given sequence, in particular as regards the processing characteristics of the medium and the quality of the coatings. The present invention therefore also relates to a process for the preparation of the impregnating medium defined above with transparent varnish for interior paints for wood, which is defined in the second independent claim.
Devono ora venire descritti più esattamente i singoli componenti del mezzo impregnante con vernice trasparente secon do la presente invenzione. The individual components of the clear varnish impregnating medium according to the present invention must now be described more precisely.
Il mezzo impregnante con vernice trasparente contiene anzitutto tra diversi liquidi, che complessivamente servono come solventi e/o agenti disperdenti. Il primo liquido é acqua; esso serve per la diluizione del legante, che in generale é una dispersione acquosa di un prodotto termoplastico polimero filmogeno, inoltre come supporto per il biocida. Il secondo liquido é un regolatore di evaporazione alifatico, esente da idrocarburi, miscibile con acqua almeno in parte. Come tali si sono dimostrati efficaci eteralcoli dal punto d'ebollizio ne tra circa 180 e 260°C, quindi in generale eteri di glicoli come etilenglicol, D- e trietilenglicol, propilenglicol, dipropilenglicol e cosi via con alcanoli a catena corta, ad esempio metanolo, etanolo, propanolo, butanolo e così via. The impregnating medium with clear varnish primarily contains between different liquids, which collectively serve as solvents and / or dispersing agents. The first liquid is water; it serves for the dilution of the binder, which in general is an aqueous dispersion of a film-forming polymer thermoplastic product, also as a support for the biocide. The second liquid is an aliphatic evaporation regulator, free from hydrocarbons, miscible with water at least in part. As such, ethereal alcohols have proved effective from the boiling point between about 180 and 260 ° C, therefore in general glycol ethers such as ethylene glycol, D- and triethylene glycol, propylene glycol, dipropylene glycol and so on with short-chain alkanols, for example methanol , ethanol, propanol, butanol and so on.
Particolarmente preferito viene dipropilenglicolmonometilete re, che é miscibile con acqua in ogni rapporto. Un compito di questo secondo liquido é di migliorare la penetrazione dei componenti del mezzo impregnante che agiscono conservando nel legno ed inoltre di regolare l'evaporazione di tutti i solventi. Particularly preferred is dipropylene glycol monomethyl ether, which is miscible with water in any ratio. A task of this second liquid is to improve the penetration of the components of the impregnating medium which act by preserving in the wood and also to regulate the evaporation of all the solvents.
Infine il mezzo impregnante secondo la presente invenzio ne contiene ancora un glicol, ad esempio propilenglicol. Esso serve da un lato come mezzo per la migliore penetrazione dell'impregnazione nel legno e d'altro lato come mediatóri'-di soluzione per biocidi non solubili o difficilmente solubili in acqua ed altri componenti. Finally, the impregnating medium according to the present invention still contains a glycol, for example propylene glycol. It serves on the one hand as a means for the best penetration of the impregnation into the wood and on the other hand as a solution medium for insoluble or hardly soluble biocides in water and other components.
Il legante del mezzo impregnante—vernice trasparente secondo la presente invenzione é opportunamente una dispersione acquo sa di una materia plastica termoplastica,filmogena, che essicca ad una pellicola chiusa. Tali dispersioni sono note in gran numero e contengono composti di polivinile, poliacrilati, po liesteri, poliuretani, poliolefine e così via. Per i mezzi secondo la presente invenzione ha dato buoni risultati una dispersione acquosa circa al 50 % di copolimeri di esteri di acido acrilico e metacrilico, ad esempio le marche Acrinal del la BASF, Ludwigshafen/Rh., BRÌI. The binder of the transparent varnish impregnating medium according to the present invention is suitably an aqueous dispersion of a thermoplastic, film-forming plastic material which dries to a closed film. Such dispersions are known in large numbers and contain compounds of polyvinyl, polyacrylates, polyesters, polyurethanes, polyolefins and so on. For the media according to the present invention, an aqueous dispersion of about 50% of copolymers of acrylic and methacrylic acid esters, for example the brands Acrinal of BASF, Ludwigshafen / Rh., BRI, has given good results.
Come pigmenti translucidi s'impiegano nel modo migliore noti pigmenti di ossido di ferro trasparenti ovvero semitrasparenti, ad esempio della gamma Luconil o Sicotrans, forniti dalla BASF, che forniscono toni di colore giallognoli, rossastri e brunastri. Talvolta si possono ancora aggiungere picco le.quantità di nerofumo colorato. As translucent pigments, known transparent or semi-transparent iron oxide pigments, for example from the Luconil or Sicotrans range supplied by BASF, are best used, which provide yellowish, reddish and brownish tones. Sometimes small amounts of colored carbon black can still be added.
L’impregnazione secondo la presente invenzione con verni ce trasparente contiene almeno un biocida ad azione conservan te. L'espressione "ad azione conservante" si riferisce sia all'impregnazione del legno nonché a quella dello strato di vernice trasparente. Viene perciò preferita una combinazione di due o più mezzi biocidi, dei quali uno nel legno agisce opportunamente contro l'infestazione dà parte di Aspergin i e altri microorganismi e alghe in modo protettivo, mentre l'altro o gli altri proteggono la vernice trasparente contro gli stessi parassiti. Hanno dato buoni risultati i prodotti Parmetol della Ditta Schtilke & Mayr, Norderstedt, BRD, come biocida dì protezione del legno, e Traetex della Ditta Acima, Buche, Svizzera. The impregnation according to the present invention with transparent varnish contains at least one biocide with a preservative action. The expression "with preservative action" refers both to the impregnation of the wood as well as to that of the transparent varnish layer. A combination of two or more biocidal media is therefore preferred, one of which in the wood acts appropriately against the infestation of Aspergin i and other microorganisms and algae in a protective way, while the other or the others protect the transparent varnish against them. parasites. Parmetol products from Schtilke & Mayr, Norderstedt, BRD, as a wood protection biocide, and Traetex from Acima, Buche, Switzerland, gave good results.
I mezzi secondo la presente invenzione possono contenere ancora ulteriori componenti, ad esempio antischiuma (AGITAN-marche, Mnzing Chemie GmbH,, Heilbronn, BRD) di silice idro foba con additivi, addtivi reologici per la regolazione delle caratteristiche di fluidità e di distensione desiderate (ad esempio SyloidED 5 di GRACE GmbH., Worms, BRD e BENTONE EW di Kronos Titan GmbH., Leverkusen, BRD), sostanze d’aroma, agenti bagnanti (ad esempio Lumiten I o Leophen RBD della BASF), antipelle , assorbitori UV, aggiunte per vernici trasparenti d’effetto, dispersori di pigmenti (ad esempio dispersore di pigmento A della BASF), agenti di condizionamento di superficie come il prodotto SLIP-AYD SL -140 di Bniel Products Compa ny, Jersey City, USA) e così via. The means according to the present invention can contain still further components, for example antifoamers (AGITAN-brands, Mnzing Chemie GmbH ,, Heilbronn, BRD) of hydrophobic silica with additives, rheological additives for regulating the desired flow and flow characteristics ( e.g. SyloidED 5 from GRACE GmbH., Worms, BRD and BENTONE EW from Kronos Titan GmbH., Leverkusen, BRD), aroma substances, wetting agents (e.g. Lumiten I or Leophen RBD from BASF), anti-skin, UV absorbers, additions for clear effect paints, pigment dispersers (e.g. pigment disperser A from BASF), surface conditioning agents such as SLIP-AYD SL -140 from Bniel Products Compa ny, Jersey City, USA) and so on .
