Embodiment 1

[0016] First use knitting needles to tuft the artificial turf on the base fabric in rows. The artificial turf is made of polyethylene and polypropylene, the height of the grass is 25mm, the base fabric is PP single-layer base fabric, and the gap between adjacent knitting needles The needle distance is 5 / 16 inches, and the number of needles is 120 needles / meter. Then heat the EVA hot-melt to 160° C., and apply it on the back of the base cloth by dripping to form an EVA hot-melt layer. The thickness of the EVA hot-melt layer is 2mm.

Embodiment 2

[0018] First use knitting needles to tuft the artificial turf on the base fabric in rows. The artificial turf is made of polyethylene material, the height of the grass is 60mm, the base fabric is PP double-layer base fabric, and the needle distance between adjacent knitting needles is is 3 / 8 inches, and the number of needles is 250 needles / meter. Then heat the EVA hot-melt to 180° C., and apply it on the back of the base cloth by dripping to form an EVA hot-melt layer. The thickness of the EVA hot-melt layer is 1 mm.

Embodiment 3

[0020] First use the knitting needles to tuft the artificial turf on the base fabric in rows. The artificial turf is made of polyamide material, the height of the grass is 45mm, the base fabric is PP single-layer base fabric plus grid cloth, and the distance between adjacent knitting needles The needle pitch between them is 5 / 8 inches, and the number of needles is 180 needles / meter. Then heat the EVA hot-melt to 170°C, and apply it on the back of the base cloth by dripping to form an EVA hot-melt layer. The thickness of the EVA hot-melt layer is 1.5mm.

Abstract

The invention discloses an artificial turf capable of being fully recycled. The artificial turf comprises artificial grass silks, base cloth and a back glue layer, wherein the back glue layer adopts an EVA (Ethylene Vinyl Acetate) hot melt glue layer. The manufacturing method comprises the following steps: tufting the artificial grass silks onto the base cloth by knitting at first, and heating the EVA hot melt glue to be 160-180 DEG C, then coating onto the rear surface of the base cloth in a dripping way. As the EVA hot melt glue is adopted as the back glue, the artificial turf is resistant to acid, alkali and corrosion, the anti-aging time is more than 6 years, the pullout force is more than 30 N, and the artificial turf can be fully recycled in a way of washing, grinding and extrusion granulation after being used for 6-8 years.

Description

technical field [0001] The invention relates to an artificial turf, in particular to a completely recyclable artificial turf and a preparation method of the artificial turf. Background technique [0002] With the continuous improvement of people's living standards, the demand for artificial turf is also increasing. At present, because the back glue used in artificial turf contains more calcium powder, styrene-butadiene rubber and other materials, artificial turf can only be thrown away as garbage after being discarded and cannot be recycled again. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a completely recyclable artificial turf and a preparation method of the artificial turf. [0004] Its technical solutions are: [0005] A fully recyclable artificial turf comprises artificial turf filaments, a base cloth and an adhesive layer, the adhesive layer being an EVA hot-melt adhesive layer. [0006] Furthe...
