[0065] 1. Preparation method of artificial turf

[0066] (1) 50 parts of 5000S resin, 40 parts of 7042 resin, 8 parts of color masterbatch, 2 parts of processing aids (including UV stabilizer, antioxidant, antistatic agent, blocking agent, dispersant), and mix well;

[0067] (2) The extrusion molding temperature is controlled at 190°C-230°C, the draft ratio is set at 5-6, the oven temperature is controlled at 95-100°C, extruded and drawn by a single-screw extruder to prepare artificial grass.

[0068] 2. The heat treatment of mesh cloth, non-woven fabric or composite cloth of non-woven fabric and mesh cloth has the following methods:

[0069] (1) Oven heating, temperature 170-175 ℃, line speed about 13m / min;

[0070] (2) Oven heating, temperature 180-185 ℃, line speed about 15m / min;

[0071] (3) Heated by hot roller, the temperature is 185-190°C, and the line speed is about 4.5m / min;

[0072] (4) The hot roller is heated, the temperature is 195-200°C, and the line speed is ab...

Embodiment 1

[0079] (1) According to 80g / m 2 Sprinkle the amount of powder evenly sprinkle PE hot melt adhesive powder in 200g / m 2 The PP single-layer woven fabric is heated in an oven, and the temperature is controlled at 130-140°C. The hot-melt adhesive powder melts and sticks to the woven fabric, and then cooled and shaped to make the base fabric.

[0080] (2) The artificial turf is tufted on the base fabric to make a semi-finished artificial turf (with hot melt adhesive powder as the bottom surface), and then the bottom surface of the semi-finished product is heated by a hot roller. The heating temperature is controlled at 150-160°C. The roots and the hot-melt adhesive powder are melted, stuck together, cooled, shaped, and the overall recyclable artificial turf is obtained.

[0081] (3) Test the pull-out force of the artificial turf and the breaking force of the artificial turf bottom, see attached table 1 for the results.

Embodiment 2

[0083] (1) According to 120g / m 2 Sprinkle the amount of powder evenly sprinkle PE hot melt adhesive powder in 150g / m 2 The PP single-layer woven fabric is heated in an oven, and the temperature is controlled at 130-140°C. The hot-melt adhesive powder melts and sticks to the woven fabric, and then cooled and shaped to make the base fabric.

[0084] (2) The artificial turf is tufted on the base fabric to make a semi-finished artificial turf (with hot melt adhesive powder as the bottom surface), and then the bottom surface of the semi-finished product is heated by a hot roller. The heating temperature is controlled at 150-160°C. The roots and the hot-melt adhesive powder are melted, stuck together, cooled, shaped, and the overall recyclable artificial turf is prepared.

[0085] (3) Test the pull-out force of the artificial turf and the breaking force of the artificial turf bottom, see attached table 1 for the results.

Abstract

The invention discloses an integrally-recoverable artificial lawn. According to the artificial lawn, the problem that tufting of an original artificial lawn is difficult is solved, tufting efficiency is high, the artificial lawn strength is high, and meanwhile the integrally-recoverable effect is achieved. The integrally-recoverable artificial lawn comprises artificial grass silk and bottom cloth, the bottom cloth contains organic make cloth, artificial grass silk is tufted on the bottom cloth containing the organic make cloth, then root melting or local melting of the artificial grass silk is conducted, the artificial grass silk and the bottom cloth form a whole after cooling shaping, and the melting point of an artificial grass silk material is lower than that of a bottom cloth material.

Description

technical field [0001] The invention relates to an artificial turf and a preparation method thereof, more specifically to an integral recyclable artificial turf and a preparation method thereof. Background technique [0002] Artificial turf is composed of three parts: artificial turf, base fabric and adhesive. Its performance is mainly reflected by artificial turf. It has good wear resistance, cushioning performance, excellent weather resistance and fresh and green appearance, making it suitable for sports turf. It is also well received by users in terms of leisure grass. The materials of artificial turf mainly include PE, PP and PA. Among them, PE has become the main raw material of artificial turf because of its excellent softness, superior aging resistance and low price. The effect of mechanical properties is to first tuft the artificial turf on the base cloth, and then apply a layer of adhesive on the bottom to fix the artificial turf, so that the artificial turf and th...
