PAGE I 鞋底用EVA防滑耐磨性能的改进研究 摘 要 本文主要通过了解EVA鞋底材料在防滑耐磨性能的改进方向，进一步分析助剂对EVA鞋底材料防滑耐磨性能的影响。其中分别以DCP交联剂用量的改变、AC发泡剂用量的改变、碳酸钙的添加以及EVA/EPDM的质量分数比例的改变进行实验数据分析。 结果表明DCP用量能直接影响分子链的交联程度，DCP用量的增大提高了鞋底用EVA材料的耐磨性能，但降低其相应的止滑性能。低交联程度下，AC用量的增加，提高鞋底用EVA材料的干止滑性能，反而降低材料的耐磨性能。高交联程度下，AC用量的增加使材料的防滑耐磨性能变化的情况与低交联度下的变化情况相同，但两者相比下高交联度的EVA耐磨性能得到提高。湿止滑性能由两个行为控制，一个是抓水能力，另一个是排水能力，而这两个能力由树脂的柔软度和硬度决定，抓水能力由树脂的柔度决定，排水能力由树脂的硬度决定。碳酸钙的存在作用与气泡相同，提高EVA树脂的干止滑性能，但碳酸钙的作用相比气泡的作用来看更能使树脂的硬度增加，使其湿止滑性能和耐磨性能下降。EPDM在树脂中所起的作用相当于DCP的作用，提高其耐磨性能和止滑性能。 关键词：鞋底用EVA；EVA；防滑；耐磨；改进 Study on the improvement of anti-slip and wear resistance of EVA for sole Abstract In this paper, the improvement direction of anti-skid and wear-resistant performance of EVA sole material is studied, and the influence of additives on the anti-skid and wear-resistant performance of EVA sole material is further analyzed. The experimental data were analyzed with the change of DCP crosslinking agent, AC foaming agent, calcium carbonate and EVA / EPDM mass fraction. The amount of DCP can directly affect the crosslinking degree of the molecular chain, and the increase of DCP can improve the wear resistance of EVA material for sole, but reduce its corresponding skid resistance. With the increase of AC content, the dry skid resistance of EVA material is improved, but the wear resistance of EVA material is decreased. At high crosslinking degree, the change of the anti-skid and wear resistance of the material is the same as that at low crosslinking degree, but the wear resistance is improved. The wet skid resistance is controlled by two behaviors, one is the ability to catch water, the other is the ability to drain water. These two abilities are determined by the flexibility and hardness of the resin, the ability to catch water is determined by the flexibility of the resin, and the ability to drain water is determined by the hardness of the resin. The effect of calcium carbonate is the same as that of bubbles, which can improve the dry skid resistance of EVA r
