Abstract

A welding cord for welding homogeneous plastic sheeting or boards, such as floor coverings, contains, as thermoplastic binder, predominantly an ethylene-vinyl acetate copolymer (EVA), if desired with admixed EPDM and polypropylene and/or polyethylene. The vinyl acetate content in the overall batch is from 10 to 20% by weight, and the proportion of assistants and fillers is from 1 to 30% by weight.

Description

Oppfinnelsen vedrører anvendelse av en sveisetråd, til sveising av homogene kunststoffbaner eller -plater, dvs. golvbelegg. The invention relates to the use of a welding wire for welding homogeneous plastic sheets or sheets, i.e. floor coverings.

Fra DE-OS 37 43 296 og DE-OS 37 43 297 (= EP-OS 0 321 760) er det kjent en homogen, flerfargestrukturert kunststoffbane eller -plate på basis av meget fylt, myknerfritt bindemiddel, særlig med etylen-vinylacetat som bindemiddel. Disse kunststoffbanene eller -platene lar seg ikke sveise til-strekkelig med vanlige sveisesnorer på basis av myknerholdig PCV. From DE-OS 37 43 296 and DE-OS 37 43 297 (= EP-OS 0 321 760) a homogeneous, multi-coloured structured plastic web or sheet is known on the basis of highly filled, plasticizer-free binder, in particular with ethylene-vinyl acetate as binder . These plastic webs or plates cannot be welded sufficiently with ordinary welding cords based on plasticizer-containing PCV.

Oppgaven til foreliggende oppfinnelse er dermed å stille til rådighet en sveisesnor som gjør det mulig med sveising av kunststoffbaner eller -plater på basis av meget fylt, myknerfritt bindemiddel og særlig for baner eller plater som tilsvarer EP-OS 0 321 760. The task of the present invention is thus to provide a welding cord which makes it possible to weld plastic webs or sheets on the basis of a highly filled, plasticizer-free binder and in particular for webs or sheets that correspond to EP-OS 0 321 760.

Sveisesnoren ifølge oppfinnelsen skal særlig gi en sveising og dermed en absolutt avtetningsfunksjon med utmerkende fasthet i sveisesømmen. Den skal være lett av- og pårullbar og også god bearbeidbar ved innlegging for hånd, samt ved en sveiseautomat. Den må være så fleksibel at en overskytende del av sveisesnoren etter innlegging og sveising legg kan bli skåret, henholdsvis kuttet, vekk ved en kniv. The welding cord according to the invention should in particular provide a weld and thus an absolute sealing function with excellent firmness in the weld seam. It must be easy to unroll and roll on and also easy to process when inserted by hand, as well as with a welding machine. It must be so flexible that an excess part of the welding cord after insertion and welding can be cut, respectively cut, away with a knife.

Mer spesifikt er oppfinnelsen rettet mot anvendelse av en sveisetråd som inneholder et bindemiddel på basis av etylen-vinylacetat-kopolymerisat (EVA), hvorved vinylacetatdelen i den samlede blandingen av sveisetråden utgjør 10 til 20 vekt-% og andelen av hjelpe- og fyllstoffer utgjør 1 til 30 vekt-# av den samlede blandingen, for sveising av gulvbelegg, idet gulvbelegget på basis av EVA inneholder en vinylacetatandel i den samlede blandingen på 3 til 14 vekt-# og en andel av fyllstoffer inkludert hjelpestoffer på 35 til 80 vekt-# av den samlede blandingen. More specifically, the invention is directed to the use of a welding wire that contains a binder based on ethylene-vinyl acetate copolymer (EVA), whereby the vinyl acetate part in the overall mixture of the welding wire amounts to 10 to 20% by weight and the proportion of auxiliaries and fillers amounts to 1 to 30 wt-# of the overall mixture, for welding floor coverings, the EVA-based floor covering containing a vinyl acetate proportion in the overall mixture of 3 to 14 wt-# and a proportion of fillers including auxiliaries of 35 to 80 wt-# of the overall mixture.

Fortrinnsvis oppviser sveisetråden som blir anvendt ifølge oppfinnelsen en vesentlig mindre andel av fyllstoffer enn kunststoffbanene eller -platene som skal sveises. Ifølge oppfinnelsen utgjør fyllstoffandelen i sveisetråden fortrinnsvis mindre enn 25 vekt-#, særlig mer enn 15 til 20 vekt-<$ >. Det er imidlertid mulig å anvende fyllstof f-f rie eller nesten fyllstoff-frie sveisetråder. Preferably, the welding wire used according to the invention has a significantly smaller proportion of fillers than the plastic webs or plates to be welded. According to the invention, the proportion of filler in the welding wire is preferably less than 25% by weight, in particular more than 15 to 20% by weight. However, it is possible to use filler-free or almost filler-free welding wires.

Bindemidlet i sveisestråden består fortrinnsvis av mer enn 60 vekt-# av etylen-vinylacetatkopolymerisat, hvorved vinylacetatandelen av EVA utgjør fortrinnsvis 15 til 30 vekt-#. Vinylacetatandelen utgjør 10 til 20 vekt-#, relativt til den totale blandingen i sveisetråden. The binder in the welding wire preferably consists of more than 60% by weight of ethylene-vinyl acetate copolymer, whereby the vinyl acetate proportion of EVA preferably amounts to 15 to 30% by weight. The vinyl acetate proportion amounts to 10 to 20% by weight, relative to the total mixture in the welding wire.

Bindemidlet i sveisetråden ifølge oppfinnelsen oppviser fortrinnsvis ingen eller bare små andeler av myknere. Eventuelt kan inntil 5$, fortrinnsvis inntil 2%, av en ftalat-mykner bli tilsatt. The binder in the welding wire according to the invention preferably has no or only small proportions of plasticizers. Optionally, up to 5$, preferably up to 2%, of a phthalate plasticizer can be added.

I motsetning til smelteklebemidler på EVA-basis som blir tyntflytende etter de når smeltetemperaturen, blir sveisetråden ifølge oppfinnelsen høyviskøs til pastaaktig ved bearbeidingstemperaturen. Blandingen som anvendes ifølge oppfinnelsen er voksfri og inneholder ingen tilsatser av lavmolekylære polyolefiner (molekylvekt under 20 000), abietinsyreestere, terpenharpikser og andre tilsatser som nedsetter smelteviskositeten som er vanlig i andre smelteklebemidler. In contrast to EVA-based hot melt adhesives, which become thin after they reach the melting temperature, the welding wire according to the invention becomes highly viscous to pasty at the processing temperature. The mixture used according to the invention is wax-free and contains no additives of low-molecular polyolefins (molecular weight below 20,000), abietic acid esters, terpene resins and other additives that reduce the melt viscosity that are common in other hot-melt adhesives.

Som fyllstoffer blir det fortrinnsvis anvendt 1 til 20 vekt-# kritt eller kaolin. Som hjelpestoffer blir det særlig anvendt inntil 3 vekt-# av et antioksiderende middel så vel som et antistatikum. 1 to 20% by weight of chalk or kaolin are preferably used as fillers. As excipients, up to 3% by weight of an antioxidant as well as an antistatic agent are used in particular.

I det følgende blir oppfinnelsen nærmere forklart ved hjelp av utførelseseksempler. In the following, the invention is explained in more detail with the help of design examples.

Deretter blir blandingen bearbeidet som følger i en Reifenhåuser-ekstruder FH 80, snekkediameter 40 mm. lengde 25 D: is mixed in a Henschel mixer for 5 min. during cooling. The mixture is then processed as follows in a Reifenhåuser extruder FH 80, screw diameter 40 mm. length 25 D:

Det plastifiserte materiale ble videre bearbeidet til en 5 mm tykk streng, avkjølt og snittet til granulat. Det således fremstilte granulatet ble bearbeidet som følger i den samme ekstruderen: The plasticized material was further processed into a 5 mm thick strand, cooled and cut into granules. The granules thus produced were processed as follows in the same extruder:

Den 4 mm tykke sveisetråden ble trukket av i et vannbad med en båndhastighet på 9 m/min, tørket og viklet på. The 4 mm thick welding wire was pulled off in a water bath at a belt speed of 9 m/min, dried and wound.

Sveisetråden lar seg godt bearbeide både med hånd og gjennom en automat. The welding wire can be easily processed both by hand and through an automatic machine.

Til utprøving av styrken i sveisesømmen blir det fra en sveiset golvbeleggsprøve snittet 50 mm bred strimmel på tvers av sømretningen og på tvers av sømretningen blir det belastet til sveisesømmen blir revet opp. Som golvbelegg ble det anvendt en banevare ifølge siste eksemplet i EP-OS 0 321 760. Den således målte strekkstyrke utgjorde 296 N. To test the strength of the weld seam, a 50 mm wide strip is cut across the seam direction from a welded floor covering sample and loaded across the seam direction until the weld seam tears open. As floor covering, a track product according to the last example in EP-OS 0 321 760 was used. The tensile strength thus measured was 296 N.
