| titleOfInvention | Grinder for high-speed motor train unit and preparation method thereof |
| abstract | The invention provides a grinder for a high-speed motor train unit and a preparation method thereof, wherein the grinder consists of a friction material and a steel backing, the friction material consists of components such as phenolic resin with specific physical properties, reinforcing fibers, fillers and the like, the components of the friction material need to be subjected to pretreatment such as mixing, drying and the like, and the steel backing needs to be subjected to pretreatment such as sand blasting, resin glue spraying and the like; and then, preparing the pre-treated friction material and the steel backing together through special hot press molding, heat treatment and other processes to obtain the grinder. The grinder improves the performances of the grinder in the aspects of metal embedding, crack dropping, wheel shaping, friction noise and the like by improving the thermal stability and enhancing the impact strength, has small damage to the wheel tread, is not easy to generate hot cracks, serious wave furrow-shaped abrasion and the like, and has important application value and wide market prospect in the field of high-speed motor cars. |
