Abstract

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.

研究了木材作为人造草坪填料减少环境污染的可行性和性能
为开发替代橡胶弹性体颗粒的环保型人造草坪填料,选取软木、软橡木、香槟皮、橡树皮、松皮、柳树皮、蛭石等7种天然材料,加工成尺寸为1-2毫米的颗粒。测试了颗粒材料的吸水性能、防霉性能、回弹性、压缩特性和休止角,并观察了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下的塑性变形范围最大,为0.21 ~ 7.82 KN。香槟树皮颗粒的回弹性最好,压缩前后回弹性分别为8.9%和7.1%,其休止角为36.8°,比热塑性弹性体(TPE)颗粒高9%。香槟皮的抗霉性优于其他6种天然材料,且其霉菌只发生在霉菌接种中心。综上所述,香槟树皮可作为替代TPE橡胶的人造草坪填充颗粒。

期刊介绍: Holzforschung is an international scholarly journal that publishes cutting-edge research on the biology, chemistry, physics and technology of wood and wood components. High quality papers about biotechnology and tree genetics are also welcome. Rated year after year as one of the top scientific journals in the category of Pulp and Paper (ISI Journal Citation Index), Holzforschung represents innovative, high quality basic and applied research. The German title reflects the journal''s origins in a long scientific tradition, but all articles are published in English to stimulate and promote cooperation between experts all over the world. Ahead-of-print publishing ensures fastest possible knowledge transfer.
