Embodiment 1
[0029] The friction material for the clutch driven disc is made of the following raw materials: cashew nut shell oil modified phenolic resin 14%, nitrile rubber powder 7%, basalt fiber 12%, steel fiber 7.4%, potassium titanate whisker 4.6%, barium sulfate 21% of powder, 12% of graphite, 6% of vermiculite, 5% of aluminum powder, 7% of barite, and 4% of brown corundum, all are mass percentages, and the total mass percentage of each component is 100%.
[0030] The preparation method of the friction material for the above-mentioned clutch driven disc, its steps are as follows:
[0031] (1) Batching: weigh each component in the formula by mass percentage;
[0032] (2) Mixing: First add basalt fiber, steel fiber and friction filler into the mixer and stir for 5-8 minutes. After mixing evenly, add cashew nut shell oil modified phenolic resin and potassium titanate whisker in turn, and then stir for 5- 8 minutes to mix evenly; the friction filler is barium sulfate powder, graphite, v...
