Abstract

A conformable sheet covering with high coefficient of friction, comprising a superficial layer made of a fine powder at least partially imbedded in a curable resin layer bonded to a lower support layer. The support layer is made of a thin sheet material having an elongation coefficient between 20 and 60% for a tensile force per linear centimeter less than 20N. There is a contact adhesive layer, protected by a pull off film, on the back side of the support layer. The new sheet covering is usable on three-dimensional surfaces.

Description

On a déjà proposé dans de nombreux brevets de réaliser des revêtements de sol, notamment pour terrains de sport, dont la couche superficielle est réalisée par de la poudrette de caoutchouc naturel ou synthétique partiellement enrobée dans une couche de résine appliquée elle-même sur une ou plusieurs couches supports. Ces couches supports peuvent être les plus diverses mais on recherche en général une couche compressible élastique, le type en étant un non-tissé aiguilleté.It has already been proposed in many patents to produce floor coverings, in particular for sports grounds, the surface layer of which is produced by natural or synthetic rubber crumb partially coated in a layer of resin applied itself on one or more several support layers. These support layers may be the most diverse, but in general an elastic compressible layer is sought, the type being a needled nonwoven.

Ces revêtements présentent une épaisseur relativement importante ne serait-ce que du fait de l'épaisseur de la couche support correspondante qui est en général supérieure à 3 millimètres pour donner une résilience sensible comme décrit dans le brevet français N° 2.112.087.These coatings have a relatively large thickness if only because of the thickness of the corresponding support layer which is generally greater than 3 millimeters to give a substantial resilience as described in French patent No. 2 112 087.

Ces revêtements sous forme de feuilles préfabriquées ne conviennent pas pour de nombreuses applications dans lesquelles le revêtement doit être aussi neutre que possible du point de vue élasticité, d'une épaisseur réduite et d'une forme mécaniquement stable. Pour répondre à ces exigences la demanderesse a déjà proposé dans son brevet français N° 2.439.084 d'appliquer la couche de résine polymérisable et de poudrette, en général une résine et une poudrette de polyuréthane, sur une couche support en non-tissé calendré. Dans le non-tissé calendré les fibres sont thermosoudées, l'épaisseur et l'élasticité sont fortement réduites, l'épaisseur se situant entre 0,1 et 1 millimètre, et la stabilité de forme est excellente. Toutefois, dans certaines applications, cette stabilité de forme constitue un inconvénient car le revêtement, du fait de la stabilité de forme de la couche support, ne s'adapte pas aux surfaces non planes ou aux applications telles que le revêtement des parties des ponts de bateaux en surface gauche, le revêtement des manches et poignées divers sur lesquels est réalisé un enroulement hélicoidal avec recouvrement d'une bande relativement étroite, etc. Un matériau en feuille sur non-tissé calendré de 0,3 mm tel que celui décrit dans le brevet français N° 2.439.084 présente une déformation à la limite de rupture de 3 à 15% pour une force de 50 à 60 N exercée sur une bande d'un centimètre de large. En fait l'allongement qu'il est possible d'obtenir au moment de l'application est extrêmement faible et même pratiquement nul.These coatings in the form of prefabricated sheets are not suitable for many applications in which the coating must be as neutral as possible from the point of view of elasticity, of a reduced thickness and of a mechanically stable shape. To meet these requirements the request deresse has already proposed in its French patent No. 2,439,084 to apply the layer of polymerizable resin and of crumb, in general a resin and a crumb of polyurethane, on a support layer of non-woven calendar. In the calendar nonwoven the fibers are heat sealed, the thickness and elasticity are greatly reduced, the thickness being between 0.1 and 1 millimeter, and the shape stability is excellent. However, in certain applications, this shape stability constitutes a drawback because the coating, due to the shape stability of the support layer, does not adapt to non-planar surfaces or to applications such as the coating of the parts of the bridges of boats on the left surface, the coating of the various handles and handles on which a helical winding is carried out with covering of a relatively narrow band, etc. A sheet material on calendar nonwoven of 0.3 mm such as that described in French patent No. 2,439,084 has a deformation at the breaking limit of 3 to 15% for a force of 50 to 60 N exerted on a strip of a centimeter wide. In fact, the elongation that it is possible to obtain at the time of application is extremely low and even practically zero.

La présente invention a pour but de résoudre ce problème et de créer un revêtement en feuille du type comportant une couche superficielle constituée par une poudrette au moins partiellement enrobée dans une couche de résine polymérisable qui soit de faible épaisseur et qui soit conformable sur une surface gauche.The object of the present invention is to solve this problem and to create a sheet coating of the type comprising a surface layer consisting of a crumb at least partially embedded in a layer of polymerizable resin which is thin and which is conformable on a left surface. .

Conformément à l'invention on utilise comme couche support un matériau en feuille mince présentant un coefficient d'allongement compris entre 20 et 60% pour une force de traction au centimètre linéaire inférieure à 20N.In accordance with the invention, a thin sheet material having a coefficient of elongation between 20 and 60% is used as the support layer for a tensile force per linear centimeter less than 20N.

Le matériau en couche mince constituant la couche support peut être un film en matière plastique obtenu par extrusion ou calendrage ayant une épaisseur comprise entre 0,01 et L mm, de préférence entre 0,05 et 0,10 mm, un textile defrma- ble du type tricot extensible ayant une épaisseur inférieure à 3 mm ou un non-tissé aiguilleté ou à liaison chimique ayant une épaisseur inférieure à 1 millimètre et un allongement avant rupture compris entre 20 et 60%.The thin layer material constituting the support layer may be a plastic film obtained by extrusion or calendering having a thickness of between 0.01 and L mm, preferably between 0.05 and 0.10 mm, a stretch fabric of the stretch knit type having a thickness of less than 3 mm or a needled or chemically bonded nonwoven having a thickness of less than 1 millimeter and a elongation before rupture between 20 and 60%.

Le film en matière plastique peut être à base de chlorure de polyvinile plastifié, de polyester ou d'acétate de cellulose. Le tricot extensible peut être réalisé avec des fibres naturelles ou synthétiques. Le non-tissé déformable est constitué par exemple par un mélange de fibres de coton et de superpolyamide liées chimiquement par un liant acrylique.The plastic film can be based on plasticized polyvinyl chloride, polyester or cellulose acetate. Stretch knitting can be made with natural or synthetic fibers. The deformable nonwoven consists for example of a mixture of cotton fibers and of superpolyamide chemically bonded by an acrylic binder.

Les valeurs limites de l'allongement et de la force de traction ont été fixées en tenant compte du fait que la force de traction qu'il est possible d'exercer sur la bande pendant l'opération de pose est limitée à une force manuelle, qu'un allongement inférieur à 20% est insuffisant pour obtenir la conformabilité nécessaire et qu'un allongement supérieur à 60% est susceptible de provoquer un déchirement de la couche superficielle de résine et de poudrette qui présente un allongement avant rupture de l'ordre de 50 à 60%.The limit values of the elongation and the tensile force have been fixed taking into account the fact that the tensile force which it is possible to exert on the strip during the laying operation is limited to a manual force, that an elongation of less than 20% is insufficient to obtain the necessary conformability and that an elongation of more than 60% is capable of causing a tearing of the surface layer of resin and of crumb which exhibits an elongation before rupture of the order of 50 to 60%.

Selon une autre caractéristique qui représente une amélioration technique importante dans le cas d'un tel matériau soumis pendant sa pose à une force de traction sensiblement parallèle à sa surface de pose, la face dorsale de la couche support est revêtue d'un adhésif de contact, de préférence un adhésif adhérant par simple pression. Ceci permet de faire adhérer la couche de revêtement sur la surface gauche selon la ligne de croupe et de l'appliquer ensuite de part et d'autre de celle-ci en exerçant sur les bords latéraux la force de traction nécessaire pour assurer l'allongement correspondant aux courbures de la surface. De manière connue la couche adhésive est protégée par un film arrachable tel qu'une feuille de papier présentant un faible pouvoir d'adhérence pour l'adhésif.According to another characteristic which represents a significant technical improvement in the case of such a material subjected during its laying to a tensile force substantially parallel to its laying surface, the dorsal face of the support layer is coated with a contact adhesive. , preferably an adhesive adhering by simple pressure. This makes it possible to adhere the covering layer to the left surface along the rump line and then apply it on either side thereof, exerting on the lateral edges the tensile force necessary to ensure elongation corresponding to the curvatures of the surface. In known manner the adhesive layer is protected by a peelable film such as a sheet of paper having a low adhesion power for the adhesive.

En conséquence le produit conforme à l'invention comporte une couche supérieure de résine polymérisée, notamment du polyuréthane dans laquelle est au moins partiellement enrobée une poudrette en un matériau compatible, notamment en polyuréthane, ayant une granulométrie comprise entre 0,2 et 1 mm, l'épaisseur d'ensemble de la couche étant comprise entre 0,5 et 3 mm, une couche support constituée par un matériau en feuille mince présentant un coefficient d'allongement compris entre 20 et 60% pour une force de traction au centimètre linéaire inférieure à 20N et liée avec la couche ci-dessus par soudage chimique lors de la polymérisation des matériaux compatibles et/ou enrobage partiel des fibres constitutives de ce matériau en feuille mince et une couche d'adhésif de contact protégée par un film arrachable sur la face dorsale de la couche support, et l'épaisseur d'ensemble du revêtement est comprise entre 0,5 et 3 mm.Consequently, the product according to the invention comprises an upper layer of polymerized resin, in particular polyurethane in which is at least partially coated a crumb of a compatible material, in particular in polyurethane, having a particle size comprised between 0.2 and 1 mm, the overall thickness of the layer being between 0.5 and 3 mm, a support layer constituted by a thin sheet material having an elongation coefficient between 20 and 60% for a tensile force per linear centimeter less than 20N and bonded with the above layer by chemical welding during the polymerization of compatible materials and / or partial coating of the constituent fibers of this thin sheet material and a layer of contact adhesive protected by a peelable film on the dorsal face of the support layer, and the thickness overall coating is between 0.5 and 3 mm.

Selon une autre caractéristique une couche de résine polymérisée est appliquée sur la couche supérieure pour enrober la poudrette.According to another characteristic, a layer of polymerized resin is applied to the upper layer to coat the crumb.

Le revêtement obtenu présente un haut coefficient de frottement qui lui donne une propriété antidérapante et il est thermiquement isolant sous une faible épaisseur, ce qui le rend particulièrement apte à être appliqué sur des manches et poignées tels que poignées de cannes à pêche, manches de raquettes de tennis, poignées de bâton de ski, guidons de bicyclettes et volants, manches d'outils et crosses d'armes, sa capacité d'allongement permettant l'application par enroulement hélicoïdal d'une bande avec recouvrement des spires. Il constitue également un matériau de recouvrement particulièrement bien adapté pour des surfaces gauches ou planes telles que surfaces supérieures de planche à voile, ponts de bateaux, marches d'escalier, présentoirs de magasins tableaux de bord et plages arrière d'automobiles, revêtements muraux divers, etc.The coating obtained has a high coefficient of friction which gives it a non-slip property and it is thermally insulating under a small thickness, which makes it particularly suitable for being applied to handles and handles such as fishing rod handles, racket handles tennis, ski pole grips, bicycle handlebars and steering wheels, tool handles and butts, its elongation capacity allowing the application by helical winding of a strip with overlapping of the turns. It is also a covering material which is particularly well suited for left or flat surfaces such as upper windsurfing surfaces, boat decks, stair treads, display units for dashboards and rear areas of cars, various wall coverings. , etc.

D'autres caractéristiques apparaîtront à la description détaillée faite ci-après de deux exemples de réalisation.Other characteristics will appear from the detailed description given below of two exemplary embodiments.

EXEMPLE 1EXAMPLE 1

On a utilisé comme couche support un film de chlorure de polyvinyle plastifié ayant une épaisseur de 0,05 mm, une résistance à la traction de ION par cm linéaire et un allongement avant rupture de 60%.

This film was coated on one side with an adhesive based on acrylic resin adhering by simple pressure and protected by a sheet of paper.

Sur la deuxième face du film en chlorure de polyvinyle on a appliqué un primaire d'adhérence puis déposé par coulée à l'aide d'une filière et à raison de 600 gr/m2 un mélange polymérisable présentant en poids la composition suivante:On the second face of the polyvinyl chloride film, an adhesion primer was applied and then deposited by casting using a die and at the rate of 600 gr / m 2 a polymerizable mixture having the following composition by weight:

Figure imgb0001
 10 seconds after application of the polymerizable resin, a layer of solid powder material consisting of a polyurethane powder having a graded particle size between 0.2 and 1 mm is spread over said layer at the rate of 200 gr / m 2 .

Pour accélérer la réticulation, on fait passer l'ensemble dans un four de séchage par air chaud à une température de 80°C durant 5 minutes.To accelerate the crosslinking, the assembly is passed through a hot air drying oven at a temperature of 80 ° C for 5 minutes.

Le matériau en feuille obtenu présente une épaisseur d'environ 1 mm et un poids de 850 à 900 gr par m2. Son allongement est de 60% sous une force de traction de 16N par cm linéaire.The sheet material obtained has a thickness of approximately 1 mm and a weight of 850 to 900 gr per m 2 .

Une des faces du non-tissé était revêtue d'une couche d'adhésif à base de caoutchouc synthétique réactivable par la chaleur protégée par un papier protecteur.One side of the nonwoven was coated with a heat-reactivable synthetic rubber-based adhesive layer protected by a protective paper.

Sur l'autre face on a déposé en continu par pulvérisation 400 gr/m2 d'une résine polyuréthane polymérisable répondant à la composition suivante :On the other side, 400 gr / m 2 of a polymerizable polyurethane resin corresponding to the following composition was deposited continuously by spraying.
