Grinding device of tread cleaning device for urban rail and preparation method thereof
The invention relates to a grinding piece and a preparation method thereof, in particular to a grinding piece of a tread cleaning device for an urban rail and a preparation method thereof, and belongs to the technical field of railway vehicle brake materials. The grinding device comprises a steel backing plate and a friction body, and is characterized in that the friction body comprises the following components, in percentage by weight: 5%-11% of a binder, 12%-24% of a tackifier, 15%-22% of a shaping agent, 12%-36% of reinforced fibers and 16%-56% of a regulator. According to the grinding device designed for the urban rails, the heat resistance and impact toughness of the grinding device are effectively improved, the heat dissipation problem caused by frequent braking of urban rail vehicles is solved, the probability that particles are transferred to wheel treads is increased, and the wheel rail adhesion coefficient is further increased. And the contact area between the hard particles in the grinding device and the wheel tread is further increased, the wheel shaping efficiency is improved, and the mechanical property and the heat dissipation performance of the grinding device are improved.
本发明涉及一种研磨子及其制备方法，尤其涉及一种城轨用踏面清扫装置研磨子及其制备方法，属于轨道车辆制动材料技术领域。一种城轨用踏面清扫装置研磨子,所述研磨子包括钢背板和摩擦体，其特征在于：所述摩擦体按重量百分比计算，包括粘结剂5％～11％，增粘剂12％～24％，修形剂15％～22％，增强纤维12％～36％和调节剂16％～56％。本发明针对城轨车轮设计的研磨子具有有效提高了研磨子的耐热性能和冲击韧性，解决了城轨车辆频繁制动带来的散热问题，提高了颗粒向车轮踏面转移的概率，进一步增大了轮轨粘着系数。进一步增大了研磨子中硬质颗粒对车轮踏面的接触面积，提高了车轮修形效率，提高了研磨子的力学性能和散热性能等优点。
