Manufacturing of friction materials, in particular brake pads and related brake pad manufacturing methods

摘要

As a method of producing a brake pad having a block of friction material, sodium hydroxide and sodium silicate are dissolved in water, an aqueous solution of sodium hydroxide and sodium silicate is mixed with commercial metakaolin until a wet paste is obtained, and dried geo The wet paste is formed and dried until a polymer aggregate is obtained, the agglomerate is pulverized into powder, the dried pulverized agglomerate is used as an inorganic geopolymer binder exclusively or almost exclusively in the friction material compound, and the raw material compound is used at the molding temperature. It is hot molded under pressure greater than the water saturation pressure.
