Embodiment 1

[0036] This embodiment provides a kind of pliable rhomboid monofilament artificial turf, the structure is as figure 1 As shown, it includes a diamond-shaped grass 1 with a rhombic cross-section. The diamond-shaped grass 1 is inserted into the base layer. The base layer includes a rubber layer 2. A felt layer 3 is arranged under the rubber layer 2, and a PU cushion layer is connected under the felt layer 3. 4. The lower surface of the PU cushion layer 4 is coated with an adhesive layer 6, and on the lower surface of the PU cushion layer 4, there is a pit corresponding to the insertion position of the diamond-shaped grass silk 1, and at the root of the lower end of the diamond-shaped grass silk 1 An anti-off fastening ring 5 is provided, and the anti-off fastening ring 5 is arranged at the pit.

[0037] The aforementioned felt layer 3 is an asphalt felt; the anti-off fastening ring 5 is a rubber ring.

[0038] The product of this embodiment is provided with an anti-loosening fa...

Embodiment 2

[0040] The present embodiment provides a method for preparing the adhesive layer 6 of a pliable diamond-shaped monofilament artificial turf, including the following specific steps:

[0041] (1) Weigh the raw materials according to the ratio, and the raw materials include the following components in parts by mass: 62 parts of natural rubber, 28 parts of hydroxystyrene-butadiene latex, 48 parts of tackifying resin, 6 parts of triethylhexyl phosphoric acid, Gur gum 5 parts, polyacrylate resin 13 parts, styrene-acrylic emulsion: 5 parts, epoxy acrylate: 3 parts, vinyl resin: 4.8 parts, styrene: 3.2 parts;

[0042](2) Add the above raw materials into the reaction kettle, set the temperature at 198°C, stir for 90 minutes, then add 4 parts of antioxidant, 4 parts of anti-aging agent, 1.6 parts of dispersant, 12 parts of filler oil, 9 parts of magnesium oxide, and oxidize 1 part of zinc, control the temperature at 168°C, and stir for 125 minutes;

[0043] (3) Cool down the mixed rubb...

Embodiment 3

[0045] This embodiment provides a kind of preparation method of soft rhomboid monofilament artificial turf, comprising the following steps:

[0046] (a) Send polyacrylate resin, vinyl resin, antioxidant, colorant, composite dispersant, POE elastic composite material, and methyl acrylate to the agitator at a stirring speed of 240-280r / min, and mix well to form a Mixture;

[0047] (b) Put the mixture into the extruder for extrusion and drawing. The temperature of each section of the extruder is 120°C, 160°C, 190°C, 230°C, 250°C; then go through the heat stretching box, heat treatment box, and finally wind up. Prepare artificial turf;

[0048] Wherein, the temperature of the heat stretching box is 135-145°C, and the temperature of the heat treatment box is 112-118°C;

[0049] (c) Twist the prepared artificial turf into strands, use a tufting machine to pass the turf through the rubber layer and the felt layer according to the specified row and needle distance, tuft it onto the ...

Abstract

The invention discloses soft rhombic monofilament artificial turf. The turf comprises rhombic grass filaments with rhombic cross sections, wherein the rhombic grass filaments are mounted and inserted in a base layer, the base layer comprises a rubber layer, a felt layer is arranged under the rubber layer, the lower side of the felt layer is connected with a PU (polyurethane) cushion layer, the lower surface of the PU cushion layer is coated with a back gum layer, pits are formed in positions, corresponding to mounting and inserting positions of the rhombic grass filaments, of the lower surface of the PU cushion layer, and anti-falling tightening rings are arranged at roots of lower ends of the rhombic grass filaments and arranged at the pits. The invention further discloses a preparation method of the soft rhombic monofilament artificial turf. The grass filaments of the turf are soft, the toughness and the elasticity are good, the grass filaments are mounted and inserted firmly and cannot loose and fall off easily, and sport injuries such as skin scratches, sprains and contusions of feet and the like can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of artificial turf, in particular to a compliant rhomboid monofilament artificial turf and a preparation method thereof. Background technique [0002] Artificial turf was first introduced in China in the late 1980s, and it was not widely promoted until the mid-to-late 1990s. Together with the plastic runway, it has become a standard model for the construction of school sports fields, replacing a large number of sports fields that were originally planted with natural grass. Although the application range of artificial turf is limited to a certain extent due to sports safety, site characteristics and public perception, with the development of science and technology, the production technology of artificial turf has been continuously innovated and improved. [0003] Sports performance Compared with natural turf, artificial turf is usually much harder, and the friction coefficient of chemical fibers is often sma...
