Description

Technical Field

[0001] The invention specifically relates to the field of artificial turf, and in particular to an artificial turf field with a soft foundation and high stability and easy drainage. Background Art

[0002] With the development of artificial turf over the years, a product portfolio of different styles and uses has been developed to continuously meet people's needs. Artificial turf fields can be divided into two uses: sports and leisure. Among them, artificial turf sports fields have very high requirements for surface sports performance, drainage and flatness. Therefore, some hardened ground is often used as the foundation, such as cement and asphalt foundation to ensure the strength, drainage and flatness of the field. The hardened foundation has high requirements for the field foundation, the construction process is long, and the cost is relatively high, which is not conducive to the promotion of artificial turf sports fields. Therefore, it is necessary to develop an artificial turf field with a soft foundation to meet people's demand for artificial turf sports fields. Summary of the invention

[0003] In order to overcome the shortcomings of the prior art, the present invention provides a highly stable and easily drainable soft-base artificial turf field. By strengthening the base layer of the entire artificial turf, the artificial turf field is made firm and flat without settling or collapse, and has excellent drainage performance and a certain elasticity.

[0004] The technical solution of the present invention to solve the above technical problems is: to provide a soft foundation artificial turf field, including an artificial turf, an elastic drainage layer, a fixed layer and a bare soil layer arranged in sequence from top to bottom, the fixed layer is composed of a mineral particle layer and a reinforcing component, and the mineral particle layer is arranged on the upper end of the reinforcing component or in the reinforcing component.

[0005] Further limiting technical solutions of the present invention:

[0006] The aforementioned mineral particle layer is one or a mixture of crushed stone, coal slag, expanded clay, cement or ash soil.

[0007] The aforementioned reinforcement component is a grid-shaped reinforcement component (32), and the grid-shaped reinforcement component (32) is located at the lower part of the mineral particle layer (31).

[0008] The aforementioned mesh reinforcement component is made of one or more of polyethylene, polypropylene, nylon, polyester, glass fiber reinforced resin and metal reinforced resin, and its weight per square meter is 0.5-5kg.

[0009] The aforementioned reinforcement component is a cell reinforcement component (33), the mineral particle layer (31) is distributed in the cell reinforcement component (33), and the cell reinforcement component comprises the following components by mass:

[0010] Base resin: 60-90 parts;

[0011] Reinforcement filler: 5-30 parts;

[0012] Masterbatch: 2-4 parts;

[0013] Antioxidant: 0.1-1 part;

[0014] Processing aids: 0.1-1 part;

[0015] The matrix resin is one or more of polyethylene, polypropylene, polyester and nylon; the reinforcing filler is one or more of glass fiber, mica powder, silica, talcum powder and carbon fiber; the antioxidant is a mixture of BASF Irganox1010 and Irgafos168; and the processing aid is erucamide, silicone or fluorinated polymer.

[0016] The height of the aforementioned cell reinforcement component is 2-25 cm, and the cell size of the cell reinforcement component is 5*5 cm to 100*100 cm.

[0017] The aforementioned fixing layer has a thickness of 3-30 cm.

[0018] The thickness of the elastic drainage layer is 0.5-5 cm, and the elastic drainage layer is one of a three-dimensional silk pad, a PE foam pad or a rubber particle pad.

[0019] The aforementioned three-dimensional silk pad is a pad layer formed by irregularly arranging round silks in an up-and-down staggered manner, and the three-dimensional silk pad is made of polyethylene, polypropylene, polyolefin elastomer, polyester and nylon or a mixture thereof.

[0020] The beneficial effects of the present invention are as follows: the present invention has low construction cost, short construction period and excellent site performance, which greatly promotes the construction and promotion of artificial turf sites. In order to provide strength and flatness, general foundations will be hardened, such as concrete and asphalt foundations, but the cost is high, the time is long, and the drainage performance is poor. The fixed layer of the present invention is composed of mineral particles and reinforcing components. When the grid reinforcement is located at the bottom of the fixed layer, it can effectively ensure that the surface layer is uniformly stressed. The grid reinforcement component forms a reinforced surface layer, making the artificial turf site flat and firm, and does not settle or collapse, greatly enhancing the strength of the foundation of the entire artificial turf, and is very suitable for a relatively flat foundation surface layer. When the mineral particle layer is in the cell reinforcement component, it can be applied to more types of mineral particle layers. The cell reinforcement component has high strength and small deformation, and becomes a reinforcement network in the fixed layer, integrating the relatively loose mineral particle layer into a whole, ensuring that the mineral particles will not be displaced, and forming a relatively uniform base layer;

[0021] Since the fixed layer is not a sealed whole and has pores in the middle, the drainage performance will be much better than the traditional hardened base layer. The reinforcing components are made of rubber and plastic materials. When the site completes its use cycle, the mineral particles and reinforcing components can be recycled and easy to operate. The elastic drainage layer is a three-dimensional wire mat, which is composed of round wires arranged irregularly up and down. It has excellent drainage performance and certain elasticity, providing drainage and elasticity for the site. BRIEF DESCRIPTION OF THE DRAWINGS
