The invention discloses a ceramic based friction material and a preparation method thereof. The ceramic based friction material has improved mechanical properties, fracture mechanical properties, thermal shock stability, stable chemical properties, excellent friction performance and wide field of use, and is composed of the following raw materials: an inorganic macromolecular polymeric binder, a reinforcing material, a friction performance conditioning agent and other materials. With the advantages of high temperature resistance, high pressure resistance and impact resistance, good anti-thermal decay performance, unique function, environmental protection and energy saving, light weight, no harm to a dual equivalent, long service life and strong environmental adaptability, the high performance friction material has a service life increased by over 2 times than that of existing products.
