The invention discloses a preparation method of potassium titanate whiskers for a friction material, and belongs to the technical field of friction materials. According to the method, titanium dioxide and a potassium source are taken as raw materials, a K2O-MoO3 composite fluxing agent is taken as a cosolvent, and the potassium titanate whisker for the friction material is prepared by adopting a fluxing agent method. A mixture of K2O and MoO3 is adopted as the composite fluxing agent to prepare the potassium titanate whisker for the friction material, and the composite fluxing agent can effectively reduce corrosion of reaction raw materials to reaction equipment; and in the reaction process, the composite fluxing agent is added in batches, so that the effect of the composite fluxing agent can be exerted to the greatest extent, the reaction of the reaction raw materials is more complete, the waste of the raw materials is reduced, and the yield is increased. 本发明公开了一种摩擦材料用钛酸钾晶须的制备方法，属于摩擦材料技术领域。该方法以二氧化钛和钾源为原料，以K2
