The invention discloses a preparation method of a modified phenolic resin friction material. A phenolic resin and nano-silica mixture is dispersed into water, and then short carbon fibers, a silane coupling agent, ethylene glycol butyl ether, hexadecyl trimethyl ammonium bromide, graphite, kaolin and micro-silicon powder are added and mixed; the mixture is subjected to ball grinding and dried; the dried matter is pressed into a blank, the blank is sintered in a high-temperature vacuum furnace, and then the modified phenolic resin friction material is obtained. By modifying phenolic resin, the friction material has good strength and a high friction coefficient.
