Problems solved by technology

[0004] (1) The pull-out force of grass silk is not enough, especially on sports grass
[0005] (2) The water permeability of the lawn system is not good, and drainage holes need to be drilled to realize the drainage function
[0006] (3) High cost, especially TPR, TPE and TPU thermoplastic elastomer plastics, the cost is much higher than styrene-butadiene and PU adhesive
[0007] To sum up, under the situation of cost control, quality improvement and product innovation, it is difficult to popularize and apply the above adhesive methods in the market

preparation example Construction

[0049] The preparation method of contrast sample is as follows:

[0050] (1) Artificial turf tufting is made into a semi-finished product on a conventional base cloth, and the artificial turf used, the line spacing and needle pitch of the tufting etc. are consistent with the embodiments of the present invention;

[0051] (2) Coat the back of the semi-finished product with styrene-butadiene and PU latex according to the normal amount of glue. After drying and curing, the finished product is obtained, and drain holes are made according to the conventional requirements.

[0052] Performance testing:

[0053] The pull-out force of the grass is tested according to the ISO4919-1978 standard required by FIFA; the water permeability of the lawn is tested according to the EN12616-200 standard required by FIFA.

[0054] Embodiment is described as follows:

[0055] In embodiment 1-8, the selected specification of base cloth A is: 120g / m 2 Non-woven +70g / m 2 Mesh cloth (mesh size 2×2m...

Embodiment 1

[0059] According to 100g / m 2 Spread the PP hot-melt adhesive powder evenly on the base fabric A compounded by the grid cloth and the non-woven fabric, and pass through the heating device at a transmission speed of 6m / min. The heating temperature is controlled at 180-190°C. After the cloth and the non-woven fabric are bonded together, the base cloth A is obtained through cooling and rolling.

[0060] According to 60g / m 2 Spread PP hot-melt adhesive powder evenly on the base fabric B combined with grid cloth and non-woven fabric, and pass through the heating device at a transmission speed of 6m / min. The heating temperature is controlled at 180-190°C. After the cloth and the non-woven fabric are bonded together, the base cloth B is obtained through cooling and rolling.

[0061] According to the corresponding needle pitch and line spacing, the artificial turf is clustered on the base fabric A (the grid surface is below) to obtain a semi-finished lawn, and the base fabric B of th...

Embodiment 2

[0063] According to 100g / m 2 Spread the PP hot-melt adhesive powder evenly on the base fabric A compounded by the non-woven fabric and the mesh cloth, pass through the heating device at a transmission speed of 5m / min, and control the heating temperature at 170-180°C. After the cloth and the non-woven fabric are bonded together, the base cloth A is obtained through cooling and rolling.

[0064] According to 60g / m 2 Spread the PP hot-melt adhesive powder evenly on the base fabric B composed of non-woven fabric and mesh cloth, pass through the heating device at a transmission speed of 5m / min, and control the heating temperature at 170-180°C. After the cloth and the non-woven fabric are bonded together, the base cloth B is obtained through cooling and rolling.

[0065] According to the corresponding needle pitch and line spacing, the artificial turf is clustered on the base fabric A (the grid surface is below) to obtain a semi-finished lawn, and the base fabric B of the same siz...

Abstract

The invention discloses a recoverable artificial lawn and a preparation method thereof. The artificial lawn has the obvious advantages of being capable of being recovered, environmentally-friendly, free of glue, capable of achieving normal water discharging without need of punching water discharging holes, and the like and has high pulling-out force. The recoverable artificial lawn comprises artificial grass silks and a base fabric, wherein the base fabric consists of a base fabric A for fixing the grass silks and a base fabric B at the bottom of a lawn body; and the base fabric A for fixing the grass silks and the base fabric B at the bottom of the lawn body are stuck together in a thermal compounding mode.

Description

technical field [0001] The invention relates to an artificial turf, in particular to a recyclable artificial turf and a preparation method thereof. Background technique [0002] Artificial turf is more and more favored by people because of its excellent performance, low price and convenient maintenance compared with natural grass. From the initial use of the football field, it is gradually derived to tennis, basketball, hockey, etc., because of its long life, not affected by the weather, and the natural grass-like sports feeling, it greatly meets the needs of sports enthusiasts. In recent years, with the development of the artificial turf industry, its application fields have gradually penetrated from traditional sports venues to leisure and entertainment venues, from the initial sports grass to today's courtyard grass, garden grass, landscape grass in hotels and supermarkets, etc. , artificial turf is gradually entering our lives. However, with the increasing application ...
