The invention discloses a preparation method of a potassium titanate whisker for a friction material, which belongs to the field of materials and is characterized in that potassium carbonate and metatitanic acid are used as raw materials, potassium manganate is used as a cosolvent, and the potassium titanate whisker for the friction material is prepared by a flux method. According to the preparation method of the potassium titanate whisker for the friction material, the potassium hexatitanate whisker is prepared by adopting the elemental phosphorus potassium and the metatitanic acid as raw materials, then the fluxing agent is used for assistance, and through the conception that the potassium manganate is added in batches, the fluxing effect of the fluxing agent can be better, the elemental phosphorus potassium and the metatitanic acid react more completely, and the potassium hexatitanate whisker is prepared. The utilization rate of the raw materials is higher, the production cost is reduced, and meanwhile, th
