Wear-resistant TPU (thermoplastic polyurethane), preparation method and homogeneous core-penetrating floor rubber
The invention discloses wear-resistant TPU (thermoplastic polyurethane), a preparation method and homogeneous core-penetrating floor rubber, and relates to the technical field of TPU materials. The wear-resistant TPU provided by the invention is prepared from the following components in parts by weight: 50-80 parts of TPU particles; 20-35 parts of an inorganic filler; 2-5 parts of polypropylene wax powder; and 1-2.5 parts of a silane coupling agent. The preparation method comprises the following steps: S1, preparing the inorganic filler; s2, mixing the materials; and S3, extruding and granulating. The homogeneous core-penetrating floor rubber is prepared from the prepared wear-resistant TPU. According to the invention, the calcium carbonate whiskers and the polypropylene wax powder are partially embedded into abundant channels in the attapulgite, the attapulgite expands after absorbing moisture, the calcium carbonate whiskers and the polypropylene wax powder are uneven on the TPU surface, and the friction force is increased; the polypropylene wax powder forms a non-smooth granular layer on the surface of the TPU, so that an object can slide when passing through the TPU surface containing the polypropylene wax powder, the scratch to the area is reduced, and the effect of improving the wear resistance of the TPU is achieved.
本申请公开了一种耐磨TPU、制备方法及同质透心地胶，涉及TPU材料技术领域。本申请的耐磨TPU，由以下按重量份数计的组分制备得到：TPU颗粒50‑80份；无机填料20‑35份；聚丙烯蜡粉末2～5份；硅烷偶联剂1‑2.5份。制备方法，包括以下步骤：S1制备无机填料；S2混料；S3挤出造粒。一种同质透心地胶，通过上述制备的耐磨TPU制备得到。本发明通过凹凸棒土内部丰富的的通道，使得碳酸钙晶须、聚丙烯蜡粉末部分嵌入至通道内，凹凸棒土吸湿后膨胀，碳酸钙晶须、聚丙烯蜡粉末会在TPU表面呈现高低不平状，增大摩擦力；聚丙烯蜡粉末在TPU的表面形成非光滑型的颗粒层，能够使物体在经过含有聚丙烯蜡粉末的TPU表面时滑过，降低对该区域的划伤，从而起到提高TPU耐磨性能的作用。
