摘要:
A thermosetting resin composite material is manufactured by forming a polybenzoxazine resin by polycondensation reaction of a compound having a phenolic hydroxyl group, primary amines, and formaldehydes in the presence of a swelling clay mineral having been subjected to organizing treatment, or by adding the swelling clay mineral to the reaction system after termination of the polycondensation reaction. A friction material is provided with the thermosetting resin composite material obtained by the above method.

The present invention provides a binder resin for a friction material, which enables high-temperature short-time thermoforming and can omit a post-curing step and suppress the generation of a pyrolysis component at molding; a friction material using the binder resin; and a binder resin composition for a friction material, which is enhanced in the heat resistance and can suppress a rapid increase of the wear amount, and in addition to these properties, which has good dynamic property and enables high-temperature short-time thermoforming. The present invention relates to a binder resin for a friction material which comprises (A) one kind or two or more kinds of polybenzoxazine resins selected from a condensation reaction product of an aminophenol compound with formaldehydes and a condensation reaction product of a bifunctional phenol compound and a bifunctional amine compound with formaldehydes; a binder resin composition for a friction material which comprises: the component (A); and further (B) one kind or two or more kinds of particles selected from an inorganic particle and an inorganic-organic composite particle, and a friction material obtained by the binder resin or binder resin composition.
