Abstract
Provided is a method of producing a friction material that can prevent occurrence of dust generation and segregation at the time of mixing raw materials of the friction material and that is resistant to deterioration of the friction material even when a phenol resin is employed as a binder and that also allows the production process to be effected safely and speedily and at a low cost. The method includes a mixing step (A) for stirring the raw materials for the friction material containing a high-ortho phenol resin, slaked lime and 3-10 wt. % of water and a forming step (B) for forming a mixture powder obtained from the mixing step (A) to a desired shape at room temperature.
Claims5
A method of producing a friction material, comprising:
- a mixing step for stirring the raw materials for the friction material containing a high-ortho phenol resin, slaked lime and 3-10 wt. % of water, wherein the high-ortho phenol resin has an ortho binding ratio of a methylene group or substituted methylene group originated from the aldehyde ranging from 50 to 98% relative to the phenolic hydroxyl group;
- and
- a forming step for forming a mixture powder obtained from the mixing step to a desired shape at room temperature.
