Abstract

The present invention relates to a plastic mat comprising a polymer alloy and intended for floor and wall surfaces, preferably for floor surfaces, the polymer alloy comprising a base material in the form of PVC plastic. According to the invention, at least that part of the mat which is intended to face outwards in a room comprises the polymer alloy, which constitutes a mixture of the base material and an alloy material intended to make the base material flexible and comprising thermoplastic polyurethane. The percent by weight of base material exceeds the percent by weight of alloy material in the polymer alloy. <IMAGE>

Description

4-58 10 15 20 25 30 35 582 I det i "Research Disclosure" nämnda materialet krävs tillsats av organiska lösningsmedel, vilket är skadligt för omgivningen, för att materialet skall hållas flytande under tillverknigen. Detta är ett krav för att materialet skall kunna användas som bestrykningsmedel på bärarmaterial såsom textilväv och liknande. 4-58 10 15 20 25 30 35 582 In the material mentioned in "Research Disclosure" is required addition of organic solvents, which is harmful for the environment, in order to keep the material liquid during manufacture. This is a requirement for the material shall be able to be used as a coating on carrier material such as textile fabrics and the like.

Föreliggande uppfinning avser att undanröja problemen med känd teknik. Detta har möjliggjorts genom en plast- matta av det inledningsvis nämnda slaget som kännetecknas av att åtminstone den del av mattan, som är avsedd att vetta utåt i ett utrymme, innefattar polymerlegeringen, som utgöres av en blandning av basmaterialet och ett legeringsmaterial, som är avsett att göra basmaterialet flexibelt, och som innefattar termoplastisk polyuretan, och att viktsandelen basmaterial överstiger viktsandelen legeringsmaterial i polymerlegeringen. Härigenom elimineras behovet av ftalater som mjukgörare, varför problemen* med emission av skadliga ämnen elimineras.The present invention seeks to eliminate the problems with known technology. This has been made possible by a plastic carpet of the type mentioned in the introduction which is characterized of at least the part of the carpet which is intended to facing outwards in a space, the polymer alloy comprises, which consists of a mixture of the base material and a alloy material, which is intended to make the base material flexible, and comprising thermoplastic polyurethane, and that the weight fraction of base material exceeds the weight fraction alloy material in the polymer alloy. This eliminates the need for phthalates as plasticizers, why the problems * with the emission of harmful substances is eliminated.

Vidare innefattar detta nya material termoplastisk polyuretan till skillnad mot det kända materialet, som innefattar värmehärdbar polyuretan. Det nya materialet blir synnerligen slitstarkt, nötnings- beständigt och mindre känsligt för friktionsvärme, varför materialet blir synnerligen lämpligt att användas som plastmattor för exempelvis golv. Dessutom utgöres huvud- delen av materialet av den billiga PVC-plasten, varför materialet blir synnerligen billigt att framställa. En annan fördel med det nya materialet beroende på att termo- plastisk polyuretan användes är att vid framställning av materialet kan spillet återanvändas. Till skillnad från det i "Research Disclosure" nämnda materialet framställs det härmed beskrivna nya materialet medelst extrudering och _ kalandrering.Furthermore, this new material includes thermoplastic polyurethane in contrast to the known material, which includes thermosetting polyurethane. The the new material becomes extremely durable, abrasion durable and less sensitive to frictional heat, why the material becomes particularly suitable for use as plastic mats for floors, for example. In addition, the main part of the material of the cheap PVC plastic, why the material becomes extremely inexpensive to produce. One other advantage of the new material due to the thermal plastic polyurethane used is that in manufacturing of the material, the waste can be reused. Unlike the material mentioned in "Research Disclosure" is produced the new material thus described by extrusion and _ calendering.

Såsom nämnts tidigare innefattar kända plastmattor för golv ett bottenskikt, avsett att anligga mot ett betong- golv, och ett slikskikt, som är avsett att beträdas. Därvid innehåller båda skikten ett basmaterial av PVC, som inne- håller mjukningsmedel innefattande ftalater.As mentioned earlier, known plastic mats include for floors a bottom layer, intended to abut against a concrete floor, and a layer of candy, which is intended to be walked on. Thereby both layers contain a base material of PVC, which contains holds plasticizers including phthalates.

Den uppfinningsenliga plastmattan kan utgöra åtminstone 10 15 20 25 30 3 0 463 582 tre olika produkter.The plastic mat according to the invention can constitute at least 10 15 20 25 30 3 0 463 582 three different products.

För det första kan plastmattan vara homogen, vilket innebär att hela mattan är gjord av polymerlegeringen och kan betraktas som ett enda slitskikt. Basmaterialet i mattan innefattar sålunda PVC-plast, vilken har blandats med ett legeringsmaterial i form av termoplastisk polyuretan för -att sålunda bilda den nya polymerlegeringen.First, the plastic mat can be homogeneous, which means that the entire carpet is made of the polymer alloy and can be considered as a single wear layer. The base material in the carpet thus comprises PVC plastic, which has been mixed with a alloy materials in the form of thermoplastic polyurethane for - thus forming the new polymer alloy.

Den andra produkten kan utgöras av två skikt, ett botten- skikt och ett slitskikt, vartdera innefattande polymer- legeringen. Detta innebär att jämfört med konventionella mattor har mjukningsmedelet innefattande ftalater ersatts i båda skikten med ett legeringsmaterial, som innefattar termoplastisk polyuretan.The second product may consist of two layers, a bottom layer layer and a wear layer, each comprising polymeric the alloy. This means that compared to conventional carpets, the plasticizer comprising phthalates has been replaced in both layers with an alloying material comprising thermoplastic polyurethane.

Den tredje produkten kan också utgöras av två skikt av vilka bottenskiktet innefattar en polymerplast, som är mjukgjord på konventionellt sätt, medan slikskiktet inne- fattar den uppfinningsenliga polymerlegeringen. Inte heller i detta fall blir det någon emission av ftalater i rummet från plastmattan, eftersom bottenskiktet innefattande det konventionella mjukningsmedlet är täckt av slitskiktet som innefattar det nya, ofarliga plastmaterialet.The third product can also consist of two layers of which the bottom layer comprises a polymer plastic, which is softened in a conventional manner, while the candy layer contains takes the polymer alloy according to the invention. Nor in this case there will be some emission of phthalates in the room from the plastic mat, since the bottom layer comprising the conventional plasticizer is covered by the wear layer which includes the new, harmless plastic material.

Den nya polymerlegeringen innefattar PVC-plast till en andel av 60-80 viktsprocent och termoplastisk polyuretan till en andel av 20-40 viktsprocent. Särskilt goda egen- skaper erhålles om polymerlegeringen innehåller 65-75 viktsprocent PVC-plast och 25-35% termoplastisk polyuretan- plast.The new polymer alloy includes PVC plastic a proportion of 60-80% by weight and thermoplastic polyurethane to a proportion of 20-40% by weight. Particularly good self- properties are obtained if the polymer alloy contains 65-75 weight percent PVC plastic and 25-35% thermoplastic polyurethane plastic.

Uppfinningen är naturligtvis ej begränsad till vad som här angivits. Sålunda är det möjligt att inom ramen för uppfinningen tillverka en plastmatta, som innehåller fler skikt än två. Det viktiga är emellertid att mattans'd översta skikt, d v s det skikt som är avsett att vetta utåt i ett utrymme, skall innehålla den nya polymerlege- ringen.The invention is of course not limited to what specified here. Thus, it is possible that within the framework of the invention to manufacture a plastic mat, which contains more layer than two. The important thing, however, is that the carpet'd top layer, i.e. the layer intended to wett outwards in a space, shall contain the new polymer alloy the ring.
