Definitions

• 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.
• 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. .
• 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.
• 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%.
• 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.
• 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%.
• the dorsal face of the support layer is coated with a contact adhesive.
• 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.
• the adhesive layer is protected by a peelable film such as a sheet of paper having a low adhesion power for the adhesive.
• 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.
• a layer of polymerized resin is applied to the upper layer to coat the crumb.
• 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.
• 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.
• a plasticized polyvinyl chloride film having a thickness of 0.05 mm, a tensile strength of ION per linear cm and an elongation before rupture of 60% was used as the support layer.
• 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.
• 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:
• 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 .

• the sheet material obtained has a thickness of approximately 1 mm and a weight of 850 to 900 gr per m 2 . Its elongation is 60% under a tensile force of 1 6 N per linear cm.
• a nonwoven consisting of a mixture of polyamide and cotton fibers linked together by an acrylic resin was used as support layer, the support layer having a surface weight of 200 gr / m 2 , a thickness of 0.7 mm and a elongation at the breaking limit of 60%.
• One side of the nonwoven was coated with a heat-reactivable synthetic rubber-based adhesive layer protected by a protective paper.
• the resin was crosslinked with evaporation of the solvents by passage through an oven at 80 ° C for 7 minutes.
• a second layer of polyurethane resin was then deposited on the upper side by spraying at a rate of 50 gr / m 2 , this resin having the following formula:
• the sheet material was passed through an oven at 80 ° C for 7 minutes to complete crosslinking and evaporation of the solvents.
• the second layer of polyurethane resin constitutes a protective film against dirt; it increases resistance to abrasion and protects the crumb which is on the surface.
