Summary: | The invention discloses a preparation method of potassium titanate. According to the preparation method, potassium carbonate and titanium dioxide are mixed for 15-20 minutes, uniformly stirred and transferred to a push slab kiln; firstly, the mixture is heated in the kiln from the room temperature, heated to 300 DEG C-320 DEG C in two hours, then heated again to 700 DEG C-720 DEG C in 6 hours, kept at the temperature for 8 hours, then heated to 900 DEG C-920 DEG C in 4 hours and kept at the temperature for 4 hours; then the mixture is cooled to the normal temperature, taken out and roughly smashed firstly, and the diameters of particles are controlled to be smaller than 1 cm; the roughly smashed material is subjected to ball milling for 10-20 hours, a product is subjected to heat treatment at the temperature of 700 DEG C-800 DEG C for one hour after ball milling, and potassium titanate is obtained. The potassium titanate prepared with the method has stable friction performance after being used in the friction material and has good abrasion performance, speed characteristic and heat recession resistance and better capability of reducing brake noise. |
