Description
Elastische bekleding.Elastic padding.
De uitvinding betreft een bekleding voor ruimten bestemd voor menselijke activiteiten zoals spart, fitness training, waterrecreatie en dergelijke. De bekleding bestaat uit een verende onderlaag waarop een elastische, dichte en slijtvaste bovenlaag aangebracht is. De bovenlaag kan daar waar nodig versterkt worden met vezelstructuren zoals weefsels uit polyestervezel.The invention relates to a coating for spaces intended for human activities such as spart, fitness training, water recreation and the like. The cover consists of a resilient bottom layer on which an elastic, dense and wear-resistant top layer is applied. Where necessary, the top layer can be reinforced with fiber structures such as polyester fiber fabrics.
Een van de toepassingen van het bekledingsmateriaal is het bekleden van de glij goten van waterglij banen. Personen glijden op een dunne laag water met grote snelheid door een bochtige baan waarbij gemakkelijk ongelukken kunnen gebeuren. Vanneer de baan en de omranding van de baan bekleed zijn met een verend materiaal zou dat de veiligheid sterk bevorderen. Het probleem is echter dat verend materiaal zoals schuimrubber gemakkelijk water opneemt en dan niet meer verend is en daarbij een oppervlak heeft dat poreus en stroef is en moeilijk te reinigen.One of the applications of the cladding material is to coat the chutes of water chutes. People slide on a thin layer of water at great speed through a winding track where accidents can easily occur. If the track and the edge of the track are covered with a resilient material, this would greatly improve safety. The problem, however, is that resilient material such as foam rubber readily absorbs water and then is no longer resilient, having a porous and non-slip surface and difficult to clean.
Gebleken is dat een combinatie van een geschuimd materiaal met een dichte oppervlaktelaag de veiligheid sterk bevordert. Het gevaar van deze constructies is echter dat bij beschadigingen van het oppervlak door mogelijke wateropname de verende werking van het schuim wordt verstoord en reparaties vrijwel onmogelijk worden.It has been found that a combination of a foamed material with a dense surface layer strongly promotes safety. The danger of these constructions, however, is that if the surface is damaged by possible water absorption, the resilience of the foam is disrupted and repairs become virtually impossible.
De verende eigenschappen van het geschuimde materiaal moeten gecombineerd worden met een zekere elasticiteit van de bovenlaag om te voorkomen dat de verbinding tussen de lagen verbroken wordt en de bekleding definitief beschadigd wordt. Een stugge bovenlaag zal scheuren in het geval dat het geschuimde materiaal te veel inveert.The resilient properties of the foamed material must be combined with a certain elasticity of the top layer to prevent the connection between the layers from being broken and the coating from being permanently damaged. A rigid top layer will tear in case the foamed material bounces too much.
In sommige gevallen kan het zinvol zijn om in de bovenlaag een vezelversterking aan te brengen. Hiermede is een vergrote scheursterkte te bereiken terwijl de vezelstructuur een oppervlaktestructuur veroorzaakt die bij sommige toepassingen gewenst is.In some cases it may be useful to provide a fiber reinforcement in the top layer. This achieves an increased tear strength while the fiber structure produces a surface structure which is desirable in some applications.
Verrassenderwijs is nu gevonden dat wanneer voor de onderlaag een cross-linked copolymeer schuim met gesloten cellen wordt gekozen met een soortelijk gewicht van circa 50 kilogram per kubieke meter en voor de bovenlaag een 2-componenten poly-urethaanhars met een rek bij breuk van circa 900 % een ideale combinatie is te bereiken. Voor toepassingen waarbij de bekleding aan water wordt blootgesteld is een cross-linked copolymeer schuim met gesloten cellen net een maximale wateropname van circa 0,6 % aan volume bij onderdompeling in water gedurende 28 dagen een noodzaak.Surprisingly, it has now been found that when a cross-linked closed-cell copolymer foam with a specific gravity of about 50 kilograms per cubic meter is chosen for the bottom layer and a 2-component polyurethane resin with an elongation at break of about 900 for the top layer. % an ideal combination can be achieved. For applications where the coating is exposed to water, a closed-cell cross-linked foam with a maximum water absorption of about 0.6% by volume when immersed in water for 28 days is necessary.
De bekleding kan op verschillende wijze aangebracht worden. Hen kan het vloeibare mengsel van de twee componenten in een laag uitstrijken over een plaat van de gewenste dikte van het cross-linked copolymeer schuim met gesloten cellen. De bekleding kan dan pas gemaakt worden op de vloer of wand van de te bewerken ruimte. Gebleken is dat de poly-urethaanhars zeer goed te lijmen is met elastische poly-urethaan 2-conqponentenhars.The coating can be applied in different ways. They can layer the liquid mixture of the two components on a plate of the desired thickness of the closed-cell cross-linked copolymer foam. The covering can only then be made on the floor or wall of the space to be processed. It has been found that the polyurethane resin can be bonded very well with elastic polyurethane 2-component resin.
In gevallen waar de bekleding in hoofdzaak vlak verwerkt wordt kan eerst de laag cross-linked copolymeer schuim met gesloten cellen aangebracht worden waarna de bovenlaag in vloeibare toestand naadloos aangebracht wordt. Hierbij kan op vooraf bepaalde plaatsen de bovenlaag dikker of dunner aangebracht worden.In cases where the coating is processed substantially flat, the closed-cell cross-linked copolymer foam layer may first be applied, after which the top layer in liquid state will be seamlessly applied. The top layer can be applied thicker or thinner at predetermined places.
