替代乒乓海绵的纺织复合材料

Study on textile composite instead of table tennis sponge

传统的乒乓海绵要经过烘料、配料、过滤、混炼、海绵的回炼、海绵硫化、切割海绵、胶海绵块、剖海绵、晒海绵等过程,工序繁多,过程复杂,为此选用聚氨酯为基体,以多层接结织物为增强体,经过浸轧、涂覆等过程制备复合材料。并对涂覆材料的耐水、耐酸、耐碱以及拉伸性能进行了测试与分析,得出最适合涂覆的树脂的种类和最佳成膜温度。通过对复合材料的硬度、厚度和回弹性的测试分析,得到制备的复合材料在厚度和硬度方面基本符合要求,但是在回弹性方面代替乒乓海绵还有待改进。

The traditional table tennis sponge material made after baking, batching, filtering, mixing, sponge recycling, sponge curing, sponge cutting, sponge rubber, sponge racking, sponge drying process, etc . There are many different processes in the preparation and processes are complexity. This study is to adopt the textile composite materials instead of ping-pong sponge. Using polyurethane as matrix, using a multi-layered fabric to reinforce the matrix, composite materials are made after padding and coating processes. The water resistance, acid resistance, alkali resistance of the coating materials were tested and analyzed, It is concluded that the best type of coating resin and optimum film forming temperature. Based on composite material hardness, thickness and resilience test and analysis, it is concluded that in terms of thickness and hardness, the prepared composite material basically meet the requirements, but there are some difference between the resilience, remains to be improved.
