Friction material
专利汇可以提供Friction material专利检索，专利查询，专利分析的服务。并且PURPOSE: To provide a friction material for automobile use, having high abrasion resistance and economical efficiency, and improved wettability to thermosetting resins and mechanical strengths, by using steel wool pretreated with a liquid thermosetting resin, as a main base.
CONSTITUTION: A liquid thermosetting resin such as resol-type phenolic resin, is absorbed to the surface of steel wool composed of fibers having diameter of 0.03W 0.1mm and length of 3W20mm, by mixing, immersion, etc. The amount of the adsorbed resin is 0.3W5wt% (as solid content). The resin is cured and bonded firmly to the steel wool by heat-treatment. 25W75%, based on the whole composition, of the treated wool is mixed with a thermosetting resin binder such as phenolic resin and a filler such as barium sulfate to obtain the objective friction material. An unmodified phenolic resin is especially preferable as the liquid thermosetting resin. Addition of 0.2W5% of a silane coupling agent, based on the solid content of the resin, is also preferable.
