Werkwijze voor het lassen van naden in een linoleum-vloerbe-dekking.____Method for welding seams in a linoleum floor covering .____
De uitvinding heeft betrekking op het dichtlassen van naden in een linoleum-vloerbedekking, met behulp van een lasdraad. _The invention relates to the sealing of seams in a linoleum floor covering, using a welding wire. _
Linoleum, bestaande uit een laag van gemalen kurk, hout-5 meel, kalksteen en pigmenten, gebonden door geoxideerde lijnolie en bevestigd op een laag.jute of gebitumineerd vilt, wordt nog steeds veelvuldig als vloerbedekkingsmateriaal gebruikt. Meestal wordt het in de vorm van lange banen op een vloer gelegd, waarbij tussen de banen naden overblijven, die 10 gedicht moeten worden.Linoleum, consisting of a layer of ground cork, wood flour, limestone and pigments, bound by oxidized linseed oil and attached to a layer of burlap or bituminized felt, is still widely used as a floor covering material. Usually it is placed on a floor in the form of long strips, leaving seams between the strips, which have to be sealed.
Voor het dichten van de naden in een linoleum-vloerbe-dekking maakt men doorgaans gebruik van een chemisch afbindende lijm (epoxylijm), die als 2-componenten-systeem wordt gelevd. Vlak voor het gebruik, d.w.z. tijdens het leggen van 15 de vloerbedekking, worden de twee componenten van de lijm met elkaar gemengd, waarna het mengsel in de vorm van een gekleurde pasta in de naden tussen de banen wordt gespoten. Na uithardin'g van de lijm kan het overtollige lijmmateriaal met een mes worden verwijderd.To seal the seams in a linoleum floor covering, a chemical-setting adhesive (epoxy adhesive) is usually used, which is supplied as a 2-component system. Just before use, i.e. during the laying of the floor covering, the two components of the adhesive are mixed together, after which the mixture is injected into the seams between the strips in the form of a colored paste. After the glue has cured, the excess glue material can be removed with a knife.
20 Het gebruik van 2-componenten-systemen voor lijmen stuit tegenwoordig in vele landen op'weerstand in verband met de giftigheid van de bestanddelen. Daarom dient naar andere las-methoden voor vloerbedekkingen te worden uitgezien.The use of 2-component systems for glues is currently encountering resistance in many countries because of the toxicity of the components. Therefore, other welding methods for floor coverings should be considered.
De uitvinding beoogt een werkwijze te verschaffen, waar-25 mee de naden in linoleum-vloerbedekkingen gemakkelijk en met eenvoudige hulpmiddelen kunnen worden gelast, zonder dat men daarbij gebruik hoeft te maken van 2-componentensystemen.The object of the invention is to provide a method with which the seams in linoleum floor coverings can be welded easily and with simple aids, without the use of 2-component systems.

Volgens de uitvinding wordt dit doel bereikt door in de naden een lasdraad uit smeltlijm te brengen, deze draad door verhitting met hete lucht te smelten en door afkoeling in de naden vast te hechten.According to the invention, this object is achieved by introducing a welding wire of hot-melt adhesive into the seams, melting this wire by heating with hot air and adhering it in the seams by cooling.
5 Een smeltlijm of "hot melt.adhesive" is een kleefstof die bij normale temperatuur vast is, maar bij verhitting smelt en dan de nodige vloeibaarheid vertoont. Wordt een dergelijke smeltlijm in gesmolten toestand op een voorwerp aangebracht en vervolgens afgekoeld, dan zal hij binnen enkele 10 sekonden vast worden en alleen als gevolg van de afkoeling de benodigde hechteigenschappen vertonen. Hoewel enkele natuurlijk voorkomende stoffen zoals pek en asfalt als voorbeelden van smeltlijmen kunnen worden beschouwd, worden de praktisch toegepaste smeltlijmen steeds uit synthetische materialen 15 bereid.A hot melt adhesive or "hot melt adhesive" is an adhesive that is solid at normal temperature, but melts when heated and then exhibits the necessary fluidity. If such a hot-melt adhesive is applied to an object in the molten state and then cooled, it will solidify within a few seconds and only show the required adhesive properties as a result of the cooling. Although some naturally occurring substances such as pitch and asphalt can be considered as examples of hot melt adhesives, the practically used hot melt adhesives are always prepared from synthetic materials.
De tegenwoordig meest bekende smeltlijmen bevatten EVA, een etheen/vinylacetaat-copolymeer als hoofdbestanddeel. Daarnaast kunnen nog diverse hulpstoffen aanwezig zijn, zoals kleverigmakende harsen, wassen, weekmakers, vulstoffen en 20 anti-oxidantia. De juiste samenstelling kan sterk uiteenlopen, afhankelijk van het gestelde doel. Deze smeltlijmen vinden toepassing in de verpakkingsindustrie, de boekbinderij, de meubelindustrie en.de schoenenindustrie.Today's best known hot melt adhesives contain EVA, an ethylene / vinyl acetate copolymer as the main ingredient. In addition, various auxiliary substances may also be present, such as tackifying resins, waxes, plasticizers, fillers and anti-oxidants. The correct composition can vary greatly, depending on the goal set. These hot melt adhesives are used in the packaging industry, the bookbinding industry, the furniture industry and the shoe industry.
Gebleken is nu, dat de smeltlijmen zich gemakkelijk tot 25 een lasdraad laten verwerken, en dat deze draad goed voor het lassen van naden in linoleumvloerbedekkingen kan worden gebruikt, zonder dat daarbij giftige dampen optreden. Het enige hulpmiddel dat men daarbij nodig heeft is een toestel voor het afgeven van hete lucht, zoals een heteluchtpistool of 30· föhn.. De smeltlijm van de lasdraad blijkt zich na afkoeling goed aan het linoleum te hechten, zodat een uitstekende afdichting van de naden wordt verkregen die het indringen van water voorkomt. Bovendien is het overtollige lasmateriaal gemakkelijk met een mes te verwijderen.It has now been found that the hot melt adhesives can easily be processed into a welding wire, and that this wire can be used well for welding seams in linoleum floor coverings, without producing toxic fumes. All that is needed is a hot air delivery device, such as a hot air gun or 30 · blow dryer. The hot melt adhesive of the welding wire appears to adhere well to the linoleum after cooling, ensuring excellent sealing of the seams is obtained which prevents the penetration of water. In addition, the excess welding material is easily removed with a knife.
35 Opgemerkt wordt, dat voor het lassen van naden in PVC- vloerbedekkingen reeds eerder gebruik is gemaakt van een 78 1 22 0 335 It should be noted that 78 1 22 0 3 has previously been used for welding seams in PVC floor coverings.

methode, waarbij in de naden een lasdraad uit PVC wordt ge ' lagd, die vervolgens met hete lucht wordt verweekt en door afkoeling vastgehecht. Het gaat daar echter om een lasdraad uit hetzelfde materiaal als de vloerbedekking. Dat men voor 5 linoleum-vloeren een lasdraad uit smeltlijm zou kunnen ge bruiken, valt uit de bekende methode voor PVC vloeren niet af te leiden.method, in which a PVC welding wire is laid in the seams, which is then softened with hot air and adhered by cooling. However, this concerns a welding wire of the same material as the floor covering. It is not possible to deduce from the known method for PVC floors that a welding wire from hot-melt adhesive could be used for 5 linoleum floors.
De uitvinding verschaft verder een lasdraad uit smeltlijm, die voor toepassing bij de beschreven laswerkwijze ge-10 schikt is. Een dergelijke lasdraad zal in diverse varianten beschikbaar moeten zijn, omdat hij in kleur bij het linoleum moet zijn verschaft. Ook is het mogelijk een transparante lasdraad te verschaffen, die voor linoleum gebruikt kan worden.The invention further provides a hot-melt welding wire which is suitable for use in the described welding process. Such a welding wire will have to be available in various variants, because it must be provided in color at the linoleum. It is also possible to provide a transparent welding wire that can be used for linoleum.
15 | Bij het uitvoeren van de laswerkwijze volgens de uitvin ding dient men er vooraf voor te zorgen, dat de naden tussen * » . de linoleumbanen een zekere breedte van b.v. 2-? 3 mpi hebben.15 | When performing the welding method according to the invention, it is necessary to ensure in advance that the seams are between * ». the linoleum strips have a certain width of e.g. 2-? Have 3 mpi.
Dit kan geschieden door de linoleumbanen op deze afstand van 'elkaar te leggen of anders door de naden met behulp van een .20 geschikt werktuig tot deze breedte open te frezen. Vervolgens wordt een lasdraad van smeltlijm, met een dikte van ca. 4 mm en van een bijpassende kleur in de open naad gelegd. Gelijk-; tijdig of kort daarna wordt een stroom hete lucht uit een hete-luchtapparaat op de draad gericht, zodat hij smelt en de 25 naad in vloeibare toestand goed opvult.This can be done by placing the linoleum strips at this distance from each other or alternatively by milling the seams open to this width using a suitable tool. Then a welding wire of hot melt adhesive, with a thickness of approx. 4 mm and of a matching color, is placed in the open seam. Equal-; timely or shortly thereafter, a flow of hot air from a hot air device is directed to the wire so that it melts and properly fills the seam in the liquid state.
Bij afkoeling stolt de smeltlijm in de naad binnen enkele sekonden en ontwikkelt hij de benodige hechteigenschappen, waardoor een stevige aaneenhechting der linoleumbanen en een goede dichting van de naad wordt bereikt. Het overtollige 30 lijmmateriaal kan daarna met behulp van een geschikt mes, dat 78 1 22 03 /; 4 Μϋ-Τ bijvoorbeeld halvemaanvormig is, worden weggesneden.When cooled, the hot melt adhesive solidifies in the seam within a few seconds and develops the necessary adhesive properties, whereby a firm adhesion of the linoleum membranes and a good sealing of the seam is achieved. The excess adhesive material can then be removed with the aid of a suitable knife, which is 78 1 22 03 /; 4 Μϋ-Τ, for example, is crescent-shaped, cut away.
Indien de linoleumbanen, zoals gebruikelijk met een waslaagje zijn bedekt, zal de smeltlijm niet daaraan hechten, zodat het overtollige lijmmateriaal kan worden verwijderd 5 zonder achterlating van resten en zonder beschadiging van het oppervlak. Mocht het linoleum een andere toplaag zonder was bevatten, of anders betrekkelijk oud en uitgedroogd zijn, dan kan men voorafgaand'aan het openfrezen van de naden of voorafgaand aan het inbrengen van de lasdraad een waslaagje op 10 het linoleum aanbrengen ter verkrijging van de nodige afstotende eigenschappen.If the linoleum strips are coated with a wax layer as usual, the hot melt will not adhere to it, so that the excess glue material can be removed without leaving any residue and without damaging the surface. Should the linoleum contain another top coat without wax, or otherwise be relatively old and dried out, a wax layer may be applied to the linoleum prior to milling the seams or prior to the insertion of the filler wire to provide the necessary repellent. characteristics.
Als smeltlijm voor - draad wordt bij voorkeur een smeltlijm op basis van etheen/vinylacetaat-copo-lymeer gebruikt, welke daarnaast nog diverse ande.re bestanddelen zoals kleverig makende harsen, wassen,- weekmakers, vul=-15 stoffen en/of anti-oxidantia kan bevatten. 'A hot melt adhesive based on ethylene / vinyl acetate copolymer is preferably used, which additionally comprises various other ingredients such as tackifying resins, waxes, plasticizers, fillers, and / or anti- oxidants. '
Voorbeeld |Banen linoleum van 2 meter breedte wordën nauw aansluitend op een vloer gelegd en op gebruikelijke wijze daar-20 aan vastgehecht. Vervolgens worden de .naden tussen de banen open gefreesd tot een breedte van 3 mm. In de naden wordt een lasdraad van 4 mm diameter en bijpassende kleur, gemaakt Uit smeltlijn op basis van een etheen/vinylacetaat-copolymeer gelegd.» Qnmiddelijk na het leggen van· de draad wordt deze met behulp van een he-25 te-lucht pistool gesmolten zodat hij de naden opvult. Door afkoeling stolt het materiaal van de draad binnen enkele se-konden onder vorming van een stevig hechtende afdichting.Example | Linoleum strips of 2 meters width are laid closely to a floor and adhered thereto in the usual manner. The seams between the strips are then milled open to a width of 3 mm. In the seams, a welding wire of 4 mm diameter and matching color, made from melting line based on an ethylene / vinyl acetate copolymer is laid. » Immediately after laying the wire, it is melted using a hot air gun to fill the seams. Upon cooling, the wire material solidifies within a few seconds to form a tightly adhering seal.
.Nadat alle naden op deze wijze zijn gedicht en voldoende zijn —: afgekoeld, wordt het overtollige materiaal van de gebruikte 30 smeltlijm met behulp van een halvemaanvormig mes verwijderd, waarbij geen sporen op de linoleumbanen worden achtergelaten.After all the seams have been closed in this manner and are sufficiently cooled, the excess material from the hot melt used is removed with the aid of a crescent-shaped knife, leaving no traces on the linoleum membranes.
Het eindresultaat is een vlakke en gladde vloerbedekking, waarin de naden nauwelijks zichtbaar zijn.The end result is a flat and smooth floor covering, in which the seams are barely visible.
