Description

Technical Field

[0001] The present invention relates to the technical field of artificial turf, and more specifically, to a joined-type artificial turf, and even more specifically, to an artificial turf with small dimensions that can be joined as needed by a connecting part according to the needs of use.

Background Art

[0002] With the progress of material science and manufacturing processes, artificial turf has become closer to natural turf in terms of color, appearance, and tactile comfort. In particular, some of the performance of artificial turf, such as evergreenness, durability, anti-aging properties, water conservation, and installation and maintenance performance, far exceeds that of natural turf. Since 2021, leisure turf has become a rapidly growing market. As artificial turf for non-sports applications, there are no restrictions, and it can be arbitrarily laid on roofs, atriums, pools, slopes, green belts, walls, pet cages, etc.

[0003] However, currently, leisure artificial turf is mainly laid in large rolls. For paving in a normal atrium, a professional paving team needs to use specialized tools, special joint adhesives, and special joint fabrics for paving. Moreover, the paved turf is fixed and cannot move freely. In case of local problems, it is difficult to repair or replace. Publication No. CN221545188U discloses a joined-type artificial turf. This disclosed patent designs a joining structure fixed to the base fabric of the turf mat. The joining pad has a disc structure, and a structure such as a cross is fixed to the bottom of the pad. This product is expensive, inconvenient for transportation, and has limited practical application scenarios.

[0004] Therefore, how to develop a simple and versatile joined-type artificial turf is a technical problem that those skilled in the art need to urgently solve.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The present invention is to at least somewhat solve one of the above technical problems in the prior art.

Means for Solving the Problem

[0006] Therefore, one of the objectives of the present invention is to provide a jointed artificial turf tile.

[0007] The jointed artificial turf tile includes an artificial turf tile, and a connecting portion is provided at the outer edge of the artificial turf tile. Preferably, the connecting portion includes a hot melt adhesive film and further includes Velcro (registered trademark) and / or a fastener. Alternatively, the connecting portion is a surface fastener. The hot melt adhesive film is provided at the central portion of the contact surface of the Velcro (registered trademark) and / or the fastener with the artificial turf tile.

[0008] Preferably, the Velcro (registered trademark) includes a pile surface and a hook surface. The pile surface includes a base surface and a lining surface, and the lining surface is provided at the outer edge of the base surface. The hot melt adhesive film is provided at the central portion of the contact surface of the lining surface with the artificial turf tile. The hook surface is selected from a pp injection molded hook or a nylon hook. The lining surface is connected to the hook surface.

[0009] Preferably, the hot melt adhesive film is provided at the central portion of the contact surface of the chain of the fastener with the artificial turf tile.

[0010] Preferably, the lining surface is a polyester fleece containing soft fine fibers, a cut pile carpet, or a loop cut pile carpet.

[0011] Preferably, the fastener is a single-opening or double-opening fastener. The width of one side of the fastener is 2 to 10 cm. The slider of the fastener is made of one or more materials among polyethylene, polypropylene, polyoxymethylene, or nylon.

[0012] Preferably, the hot melt adhesive film is one or a combination of one or more of a TPU adhesive film, a PO adhesive film, a PA adhesive film, or an EVA adhesive film.

[0013] The hot melt adhesive film is a film manufactured by methods such as casting, rolling, extrusion, or blade coating using a polymer resin material. The adhesive film has a uniform thickness, can be used simply and efficiently, does not have solvent volatilization during use, and is environmentally friendly.

[0014] Furthermore, since the curing temperature of the adhesive film is 100 to 125 °C, it is a medium-temperature curing type adhesive for a structure with advantages such as high adhesive strength, excellent fracture toughness, moisture and heat aging resistance, and fatigue resistance.

[0015] Preferably, the jointed artificial turf tile includes a backing and the turf provided on the backing. The backing is one or a combination of one or more of a PP woven fabric, a non-woven fabric, a hemmed recycled polyester fabric, a mesh, or a backing of a hot melt adhesive. The hot melt adhesive film is provided at the center of the lining surface and / or the contact surface of the fastener string with the backing.

[0016] Furthermore, the tips and ends of the Velcro (registered trademark) and the tips and ends of the fastener string are all fixed to the artificial turf tile by sewing.

[0017] Another object of the present invention is to provide an artificial turf including the above jointed artificial turf tile.

[0018] Preferably, the jointed artificial turf tiles are connected by a connecting portion.

Effects of the Invention

[0019] As described above, the present invention achieves at least the following technical effects.

[0020] 1) The present invention joins small-sized artificial turf tiles as needed by a connecting part, which is not only simple and efficient, but also can achieve stable connection without the need for conventional joint adhesives, can cope with flexible and diverse usage scenarios, is easy to carry, environmentally friendly, and reusable.

[0021] 2) The present invention installs a connecting part on small-sized artificial turf tiles by a simple process and realizes mass production by attaching a hot melt adhesive film. In addition, the hot melt adhesive film used is environmentally friendly, pollution-free, has strong resistance to the thickness of the turf and the backing material, and can meet all needs.

[0022] 3) The artificial turf tile designed in the present invention is a turf tile with a flexible backing that is convenient for carrying, transporting, and storing, can be joined as needed, and has a wide range of application scenarios, such as being used in atriums, floor mats for outdoor tents, picnic mats, roof covers, etc.
