Description

Technical Field

[0001] The present application relates to the technical field of artificial turf, and in particular to a preparation method of a golf practice mat and a golf practice mat. Background Art

[0002] At present, the common artificial turf uses glue to bond the grass surface layer and the buffer layer together, but the fixing effect is not reliable and it is easy to separate. In addition, the glue is usually a solvent-based styrene-butadiene glue system, and the organic volatiles after processing have adverse effects on the environment and human body, which cannot meet environmental protection requirements.

[0003] In traditional lawns, the tufting of curved fibers and the tufting of straight-curved mixed fibers are tufted separately on different base fabrics, which are then cut and spliced ​​together to form a complete grass surface layer. This consumes a lot of manpower, has low production efficiency, and cannot achieve uniform specifications.

[0004] Therefore, a method for preparing a golf practice mat and a golf practice mat are needed to at least partially solve the above problems. Summary of the invention

[0005] A series of simplified concepts are introduced in the invention summary of this application, which will be further described in detail in the detailed description.

[0045] like Figure 1 As shown, the first aspect of the present application discloses a method for preparing a golf practice mat. The preparation method comprises the following steps: Step S10: preparing curved fibers 111 and straight fibers, and plying the curved fibers 111 and the straight fibers to prepare straight-curved mixed fibers 112. Step S20: providing a base fabric layer, tufting the curved fibers 111 to the base fabric layer, and obtaining an intermediate product layer. Step S30: tufting the straight-curved mixed fibers 112 to the intermediate product layer to form a grass surface layer 110. Step S40: providing a cushion layer 130 and a hot melt adhesive layer 120, attaching the hot melt adhesive layer 120 to the grass surface layer 110, and attaching the cushion layer 130 to the hot melt adhesive layer 120, and forming a golf practice mat by a thermal composite process with the grass surface layer 110, the hot melt adhesive layer 120, and the cushion layer 130. The grass surface layer 110, the hot melt adhesive layer 120, and the cushion layer 130 all contain polyolefin materials.

[0046] According to the present application, the hot melt adhesive layer 120 is disposed between the grass surface layer 110 and the cushion layer 130, and the grass surface layer 110, the hot melt adhesive layer 120 and the cushion layer 130 are bonded together by a thermal composite process, so that the fixing effect is reliable and it is not easy to separate. The golf practice mat contains polyolefin material, which is healthy and odorless, meets various usage scenarios, and can be recycled after being discarded, which has great advantages in environmental protection. The two tufting operations are performed on the same base fabric layer, so that it can be completed on the production line by a machine, which greatly improves the production efficiency and has uniform product specifications.

[0047] Specifically, the raw materials for preparing the curved fiber 111 include, by weight, 90 to 95 parts of polypropylene, 5 to 10 parts of maleic anhydride grafted polyethylene, 3 to 10 parts of masterbatch, and 1 to 2 parts of polyphthalamide. The raw materials are extruded, stretched, air-deformed, and rolled to obtain the curved fiber 111. The prepared curved fiber 111 is 500 to 2000 dtex. In the intermediate product layer, the height of a single cluster of curved fibers 111 is 8 to 15 mm, and contains 4 to 12 curved fibers 111. The number of tufting needles of the curved fiber 111 is 240 to 350 needles / m. Multiple clusters of curved fibers 111 are arranged at a preset distance along the first direction, and the preset distance is 5 / 32 to 3 / 8 inches. In other words, multiple clusters of curved fibers 111 are arranged in rows, and the spacing between adjacent rows is 5 / 32 to 3 / 8 inches.

[0048] The raw materials for preparing the straight fiber include, by weight: 75-95 parts of linear low-density polyethylene, 0-20 parts of high-density polyethylene, 5-10 parts of maleic anhydride grafted polyethylene, 3-10 parts of masterbatch, 1-2 parts of smooth masterbatch, and 1-2 parts of polyphthalamide. The raw materials are extruded, stretched, shaped, rolled, and twisted to obtain straight fiber. The prepared straight fiber is 700-2500 dtex. Adding maleic anhydride grafted polyethylene to the raw materials can increase the polarity of the fiber material and enhance the composite performance of the grass surface layer 110 and the hot melt adhesive layer 120.

[0049] In the grass surface layer 110, a single tuft of straight and curved mixed silk fibers 112 has a height of 20 to 50 mm and contains 8 to 20 straight and curved mixed silk fibers 112. The tufting density of the straight and curved mixed silk fibers 112 is 20,000 to 40,000 needles / m 2 .

[0050] In one embodiment, the needle tufting can be designed by intelligent program to arrange and combine the curved fibers 111 and the straight and curved mixed fibers 112 into any pattern on the base fabric layer without cutting or splicing, making the processing more efficient.

[0051] The base fabric layer may include 1 to 3 layers of anti-aging polypropylene base fabric, thereby extending the service life of the golf practice mat. The density of the base fabric layer is 90 to 200 g / m3 .

[0052] The hot melt adhesive layer 120 includes at least one of a polyolefin hot melt adhesive film, an ethylene / vinyl acetate copolymer hot melt adhesive film and a thermoplastic polyurethane elastomer hot melt adhesive film. The thickness of the hot melt adhesive layer 120 is 0.01-0.5 mm.

[0053] The cushion layer 130 may be a foamed polyethylene layer, thereby improving the shock absorption and sports performance of the golf practice mat. The density of the cushion layer 130 is 30 to 70 g / cm 3 The thickness of the cushion layer 130 is 3 to 10 mm.

[0054] In one embodiment, the thermal composite process uses infrared thermal radiation heating. The infrared wavelength of infrared thermal radiation heating is preferably 8000-12000nm. Polyolefin materials have the best absorption effect on infrared energy within this wavelength range, so that the heating effect is good. Preferably, the heating temperature of infrared thermal radiation heating is 90-160°C.

[0055] After the grass surface layer 110, the hot melt adhesive layer 120 and the cushion layer 130 are thermally laminated, a cooling step may be further included. The thermally laminated product is cooled at room temperature to obtain a golf practice mat. The room temperature is, for example, 20 to 25°C.
