Problems solved by technology

[0004] However, because the above waste tire rubber fragments are black, they absorb sunlight and the temperature of the stadium rises, so there is a problem that not only the sports environment is deteriorated, but also if the temperature exceeds 30 degrees Celsius in summer, the Rubber fragments produce a pungent smell, and adhere to rubber fragments melted by scorching ground heat or generate harmful gas, and generate a lot of frictional heat while the moisture content is low, so that there is a risk of burns when the user slips and falls
[0005] In particular, in the case of using waste tire rubber chips for a long time, there is a problem that dust is generated, thereby not only releasing harmful components such as heavy metals, but also attaching dust to shoes or clothes of users who use artificial turf, thereby damaging the user's healthy
[0006] In addition, in order to eliminate the problem of waste tire rubber fragments as described above, elastic polymers made by crosslinking SEBS or EPDM rubber are widely used, but these elastic polymers also contain chemical substances harmful to the human body, so there is a long-term Time or many problems such as the inherent smell or bad smell of chemicals in the hot summer

Embodiment 1

[0050] After mixing 10wt% zeolite and 20wt% polyethylene, stir and mix at 85°C-110°C for about 20 minutes, add 10wt% bark powder (pine bark), 5wt% sumac powder, 5wt% cinnamon powder, 20wt% carbonic acid Calcium, 20wt% SEBS, 10wt% oil, stirred and mixed at 80°C-100°C for about 30 minutes, and then extruded.

[0051] As a result, such as image 3 As shown, the granular environment-friendly filler without surface cracking is molded.

Embodiment 2

[0053] After mixing 10wt% zeolite and 20wt% polyethylene, stir and mix at 85°C-110°C for about 20 minutes, add 10wt% bark powder (pine bark), 5wt% sumac powder, 5wt% cinnamon powder, 20wt% carbonic acid Calcium, 20wt% SEBS, 10wt% oil, after stirring and mixing for about 30 minutes at 80°C-100°C, formed it into a test piece (5cm×5cm), and tested its antibacterial property.

[0054] At this time, a stomacher film (5 cm×5 cm) was used as a control group, and the results are shown in [Table 1] below.

Abstract

The present invention relates to an eco-friendly filler for artificial grass and a manufacturing method thereof and, more specifically, to an eco-friendly filler for artificial grass, which consists of natural components and has mothproof, antibacterial and water purification functions, and a manufacturing method thereof. The eco-friendly filler (10), which is filled by forming a filler layer (30)with the predetermined thickness on foaming paper (22) to be located between file yarn (21) of an artificial grass structure (20), comprises 8-15 wt% of tree balk powder, 8-15 wt% of zeolite, 3-8 wt%of lacquer powder or a lacquer liquid, 3-10 wt% of cinnamon powder, 15-25 wt% of calcium carbonate, 15-25 wt% of polyethylene (PE), 15-25 wt% of one or more elastic materials selected among SEBS, latex and silicon rubber and 5-15 wt% of oil.

Description

technical field [0001] The present invention relates to a kind of environment-friendly filler for artificial turf and its manufacture method. As far as the environment-friendly filler for artificial turf is concerned, polyethylene (PE) and styrene-ethylene-butylene-styrene (SEBS, Stylene -ethylene / butylene-stylene) are mixed and extruded on environment-friendly natural materials, so that they have rainwater purification, insect-proof, antibacterial functions, and are harmless to the human body. Environmentally-friendly natural materials include bark powder (pine bark, pine nut bark and other coniferous trees) bark powder), cinnamon powder (bark powder of Lauraceae such as laurel and cinnamon), sumac powder (or sumac sap), etc. Background technique [0002] In order to prevent dust, natural turf is installed on baseball fields and football fields. Natural turf is expensive and difficult to manage. Therefore, artificial turf is being installed recently. Artificial turf can be ...
