Description

459 811 Den svenska patentansökan 8106537-7 (Tikkurilan Väritehtaat Oy) beskriver ett sätt att minska formaldehydemissionen fràn spànskivor, genom ytbehandling med en komposition innehållande cyklisk urea. Denna metod anvisar emellertid ingen lösning på problemet att minska emissionen från en lackerad yta.. 459,811 Swedish patent application 8106537-7 (Tikkurilan Väritehtaat Oy) describes a method of reducing formaldehyde emission from chipboard, by surface treatment with a composition containing cyclic urea. However, this method does not provide a solution to the problem of reducing the emission from a painted surface.

Europapatentpublikationen 43036 (Vianova) beskriver ett förfa- rande för att minska formaldehydemissionen från syrahärdande alkyd-karbamidlacker genom tillsats av etylenurea. Den erhåll- na effekten är emellertid relativt kortvarig med denna metod.European Patent Publication 43036 (Vianova) describes a process for reducing formaldehyde emission from acid-curing alkyd-urea paints by the addition of ethylene urea. However, the effect obtained is relatively short-lived with this method.

Dessutom verkar tillsatsen av etylenurea inhiberande på härd- ningsförloppet och försämrande på den färdiga filmens egenska- per.In addition, the addition of ethylene urea has an inhibitory effect on the curing process and on the properties of the finished film.

Avsikten med föreliggande uppfinning är att åstadkomma en per- manent minskning av formaldehydemissionen från föremål, som ytbehandlas med aminohartshaltiga kompositioner. Den formalde- hydemissionssänkande effekten, som àstadkommes enligt förelig- gande uppfinning, bygger pá en reaktion mellan en omättad förening, som företrädesvis utgöres av en bindemedelskompo- nent, t.ex. en alkyd såsom tallfettsyraalkyd, DCO-alkyd (dehydratiserad ricinoljealkyd) eller sojaalkyd, och formalde- nyd, vilken reaktion katalyseras med peroxid, exempelvis di- bensoylperoxid. Härvid ingår lämpligen den omättade föreningen i ytbehandlingskompositionen i en mängd av 5-70 viktprocent, företrädesvis 10-40 viktprocent, medan peroxiden användes i en mängd av 0,1-2 viktprocent, företrädesvis 0,2-0,5 viktprocent.The object of the present invention is to provide a permanent reduction of the formaldehyde emission from objects which are surface treated with amino resin-containing compositions. The formaldehyde emission lowering effect achieved according to the present invention is based on a reaction between an unsaturated compound, which preferably consists of a binder component, e.g. an alkyd such as tallow fatty acid alkyd, DCO alkyd (dehydrated castor oil alkyd) or soy alkyd, and formaldehyde, which reaction is catalyzed by peroxide, for example dibenzoyl peroxide. The unsaturated compound is suitably included in the surface treatment composition in an amount of 5-70% by weight, preferably 10-40% by weight, while the peroxide is used in an amount of 0.1-2% by weight, preferably 0.2-0.5% by weight.

Genom användning av en sådan ytbehandlingskomposition åstad- kommes en väsentligt minskad formaldehydemíssíon.By using such a surface treatment composition, a significantly reduced formaldehyde emission is achieved.

Ytbehandling enligt föreliggande uppfinning medför även för- bättrade lackfilmsegenskaper hos lackfilmen på de lackerade föremålen vad avser ytbeständigheten mot inverkan av olika_ agens. Se tabell 2. r Föreliggande uppfinning avser ytbehandlade föremål generellt, 459 811 företrädesvis dock sådana av trä eller träbaserade skivmate- rial (board, spànskivor etc), som ytbehandlats med klara och/eller pigmenterade lacker, vilka innehåller ett eller flera aminohartser. Som exempel på sådana hartser kan nämnas karbamid-formaldehydhartser, melamin-formaldehydhartser, fenolhartser, bensoguanaminhartser samt derivat av dessa såsom t.ex. metyl- eller butyletrar.Surface treatment according to the present invention also results in improved lacquer film properties of the lacquer film on the lacquered objects with respect to the surface resistance to the action of various agents. See Table 2. The present invention relates to surface-treated articles in general, but preferably to those of wood or wood-based board materials (board, particle board, etc.) which have been surface-treated with clear and / or pigmented varnishes which contain one or more amino resins. Examples of such resins are urea-formaldehyde resins, melamine-formaldehyde resins, phenolic resins, benzoguanamine resins and derivatives thereof such as e.g. methyl or butyl ethers.

Som exempel pà andra i sådana lacker vanligen förekommande komponenter kan nämnas bindemedel såsom alkyder, polyestrar, akrylater, hårdare såsom toluensulfonsyra, fosforsyra, etyl- fosforsyra, samt organiska lösningsmedel, pigment, fyllnads- medel, tillsatsmedel och hjälpmedel.Examples of other components commonly used in such paints are binders such as alkyds, polyesters, acrylates, hardeners such as toluenesulfonic acid, phosphoric acid, ethylphosphoric acid, as well as organic solvents, pigments, fillers, additives and auxiliaries.

Den formaldehydsänkande effekten som âstadkommes enligt före- liggande uppfinning framgår av nedanstående exempel och av tabell l, där "Kammarvärde mg/ma" avser provning enligt den s.k. kammarmetoden: CEN TC N 76D, 1982. Enligt denna metod placeras det provade föremålet under definierade betingelser i en kammare med viss luftomsättning varvid jämviktskoncentra- tionen av formaldehyd i luften uppmätes och anges i mg/m”.The formaldehyde lowering effect achieved according to the present invention is shown in the examples below and in Table 1, where "Chamber value mg / ma" refers to testing according to the so-called chamber method: CEN TC N 76D, 1982. According to this method, the tested object is placed under defined conditions in a chamber with a certain air circulation, whereby the equilibrium concentration of formaldehyde in the air is measured and stated in mg / m '.
