The invention relates to a grinding device for a high-speed train and a preparation method of the grinding device, and belongs to the technical field of railway vehicle braking materials. The grinding device for a high-speed train is characterized in that the grinding device adopts double friction bodies, the double friction bodies are formed by pressing a black friction body on the surface and a colored friction body inside, and the thickness of the black friction body is 27-29 mm; the thickness of the colorful friction body ranges from 13 mm to 15 mm, and the colors of the colorful friction body comprise RAL3009 oxidized red, RAL1001 light yellow and RAL9002 grey white. When the grinding piece is abraded to a limit, the friction surface is changed from original black to other colors, and the abrasion limit state of the grinding piece can be judged by observing the color of the friction surface. The grinding device has the advantages that normal functions of cleaning, tackifying, shaping and the like of the tread cleaning device are achieved, meanwhile, the situation that a back plate is abraded due to the fact that the grinding unit is not replaced in time is prevented, and the grinding device has excellent tackifying performance and shaping performance. The abrasion resistance is greatly improved, and enough time is reserved for replacement of the grinding block. And the bonding strength of the grinding sub-backboard is effectively improved.
本发明涉及一种高速列车用研磨子及其制备方法,属于轨道车辆制动材料技术领域。一种高速列车用研磨子,所述研磨子采用双摩擦体,所述双摩擦体由表面的黑色摩擦体和里面的彩色摩擦体压制组成,所述黑色摩擦体的厚度为27mm‑29mm;所述彩色摩擦体的厚度为13mm‑15mm,所述彩色摩擦体的颜色包括RAL3009氧化红色、RAL1001淡黄色和RAL9002灰白色。当研磨子磨耗到限时,摩擦面由原本的黑色变成其他颜色,观察摩擦面颜色便可判断研磨子磨耗到限状态。本发明的优点是实现踏面清扫装置的清扫、增粘、修形等正常功能的同时防止未能及时更换研磨子而造成背板磨损的情况出现,具有优异增粘性能和修形性能。极大地提高了耐磨性能,给研磨子更换预留足够时间。有效提高研磨子背板粘接强度。
