To develop an eco-friendly artificial turf filling for replacing rubber elastomer particles, seven kinds of natural materials (cork, soft oak, champagne bark, oak bark, pine bark, willow bark, and vermiculite) were selected and processed into particles with a dimension of 1–2 mm. The water absorption performance, mold resistance, resilience, compression characteristics, and the repose angle were tested, and the surface microscopic morphology of granular materials was observed. The experimental results showed that the champagne bark had the largest plastic deformation range under pressure load, which was 0.21–7.82 KN. And the champagne bark particles had the best resilience, which was respectively 8.9 % and 7.1 % before and after compression, and its angle of repose was 36.8°, which was 9 % higher than that of the thermoplastic elastomer (TPE) particle. Additionally, champagne bark had better mold resistance compared with the other six natural materials, and its mold only occurred in the mold inoculation center. In conclusion, champagne bark could be considered as an artificial turf filling granule to replace TPE rubber.

木材作为人造草坪填料减少环境污染的可行性及性能

为了开发替代橡胶弹性体颗粒的环保型人造草坪填充物，选择了七种天然材料（软木、软橡树皮、香槟树皮、橡树皮、松树皮、柳树皮和蛭石），并将其加工成一定尺寸的颗粒。 1-2 毫米。测试其吸水性能、防霉性、回弹性、压缩特性、安息角，并观察颗粒材料的表面微观形貌。实验结果表明，香槟树皮在压力载荷作用下塑性变形范围最大，为0.21~7.82 KN。其中香槟树皮颗粒的回弹性最好，压缩前后分别为8.9%和7.1%，其安息角为36.8°，比热塑性弹性体(TPE)颗粒高9%。此外，与其他六种天然材料相比，香槟树皮具有更好的防霉性，其霉菌仅发生在霉菌孕育中心。综上所述，香槟树皮可以考虑作为替代TPE橡胶的人造草坪填充颗粒。
