Problems solved by technology

However, the current ordinary artificial turf still has certain limitations and disadvantages in terms of function: poor elasticity and noise buffering performance: after long-term use, the lawn will harden, the lawn silk will be worn and broken, and the whole lawn will not be elastic. And the buffering effect of the surface of the lawn on noise is very weak; the anti-environmental interference is poor: in cold winter, due to the short light time and the relatively large temperature difference between day and night, the temperature on the surface of the field at night is extremely low, which is not conducive to athletes. At the same time, due to the low temperature, the hardness of grass silk and other field materials becomes larger, and it is more likely to be scratched when falling during sports, so the safety is relatively low; Very high, usually reaching 70-80 degrees Celsius, athletes are prone to burns when they touch the ground, so the safety is relatively low

Embodiment 1

[0027] A filler combination includes a filling particle group and a covering particle group; the filling particle group includes cork particles, and the particle diameter of the cork particles is 2 mm; the covering particle group includes covering particles.

[0028] Such as figure 1 As shown, the shape of the cork particles is n-pyramidal, n≥3; the particle size and conical shape of the cork particles are limited, and the conical shape has an apex angle, which can reduce the contact area when the cork particles collide , reduce the viscosity between particles, improve rebound and cushioning efficiency.

[0029] The covering particles are EPDM particles with a particle size of 3mm.

Embodiment 2

[0031] The present embodiment is characterized in that the cork particles are round or oval in shape, and the rest of the structures and features are the same as in Embodiment 1.

Embodiment 3

[0033] A filler combination includes a filling particle group and a covering particle group; the filling particle group includes coconut shell particles, and the particle diameter of the coconut shell particles is 2mm; the covering particle group includes covering particles.

[0034] The shape of the coconut shell particles is n-pyramidal, n≥3.

[0035] The covering particles are TPE particles with a particle size of 4mm.

Abstract

The invention discloses a filler combination and an artificial turf. The filler combination comprises a filler particle group and a cover particle group. The filler particle group comprises at least one of softwood particles and coconut shell particles, and the cover particle group includes cover particles. The artificial turf comprises a base fabric and artificial grass, and the artificial grassis fixed to the base fabric. The artificial turf further includes a filling layer and a fixing layer which are sequentially stacked on the base fabric from top to bottom. The artificial grass extendsupwards from the base fabric and passes out of the fixing layer and the filling layer, and the filling layer is formed by laying the filler combination. The filling layer comprises a covering fillinglayer and a buffering filling layer, the covering filling layer is formed by laying the covering particles group, and the buffering filling layer is laid by the filling particle group. The buffering filling layer of the artificial turf has good cushioning performance, and the covering filling layer is used as the turf surface to maintain the overall structure of the turf and prevent the bufferingfilling layer from being washed away by rainwater.

Description

technical field [0001] The invention relates to a filler combination and an artificial turf, belonging to the technical field of artificial turf components. Background technique [0002] With the development and progress of science and technology, the application field of artificial grass is constantly expanding. At present, the application of artificial grass gradually extends to sports, leisure, aerospace, building materials, military and other aspects; therefore, artificial grass is becoming more and more popular among people. However, the current ordinary artificial turf still has certain limitations and disadvantages in terms of function: poor elasticity and noise buffering performance: after long-term use, the lawn will harden, the lawn silk will be worn and broken, and the whole lawn will not be elastic. And the buffering effect of the surface of the lawn on noise is very weak; the anti-environmental interference is poor: in cold winter, due to the short light time an...
