一种基于EPDM复合型塑胶跑道底部弹性层的铺设方法
摘要：
本发明公开了一种基于EPDM复合型塑胶跑道底部弹性层的铺设方法，包括以下步骤：步骤1)、基面处理：步骤2)、涂布防水底漆：步骤2)、涂布防水底漆：步骤3)、安装框模：步骤4)、弹性层铺设：步骤5)、弹性层表面修补。本发明工序简单，具有贴合度高、使用寿命长的优点，基面进行酸洗可以将其表面细孔中的杂物彻底清除，这样防水底漆会完全渗透到其表面的细孔中，形成互相渗透黏接，避免出现分层和产生气泡的问题，通过弹性层表面修补，可以有效解决弹性层在铺设后因下榻而导致整体平整度下降了问题，使得弹性层与面层贴合的更加完美，避免因空隙导致出现空心的问题，为运动员训练提供安全保障。
摘要（英）：

The invention discloses a method for laying an elastic layer at the bottom of a composite plastic track on the basis of EPDM. The method comprises the following steps of: step 1), base surface treatment, step 2), coating of a waterproof primer, step 3), installing of a frame mold, step 4), laying of the elastic layer, and 5) repairing of the surface of the elastic layer. The method has the advantages of simple process, high bonding degree and long service life. The impurities in the pores on the surface of the base surface can be completely removed by pickling, in this way, the waterproof primer will penetrate completely into the pores of the surface, and interpenetrating bond is formed to avoid delamination and bubble formation. By repairing the surface of the elastic layer, the problem that the overall flatness of the elastic layer is reduced because the elastic layer is laid down can be effectively solved. The elastic layer is more perfectly attached to a surface layer, and the problem of hollowness due to gaps is avoided. The safety guarantee is provided for training of athletes.
