NOVOLAK-TYPE PHENOL RESIN COMPOSITION AND FRICTIONAL MATERIAL
Document Type and Number:
Japanese Patent JP2001139767
Kind Code:
A
Abstract:

To obtain a phenol resin composition excellent in alkali resistance and flexibility, having fast-curability, good in moldability, and hardly having blocking properties because of a high melting point, and further to provide a frictional material by using the composition as a binder.

This triazine-modified novolak-type phenol resin composition is the one comprising a novolak-type phenol resin composed of phenols, triazines and aldehydes, and is characterized by the novolak-type phenol resin of a high- ortho type resin having ≥1.0 rate of the ortho-position to the para-position (ortho-position/para-position) of the methylene bond to a phenol nuclear.
