Title:
PHENOLIC RESIN COMPOSITION
Document Type and Number:
Japanese Patent JP3473928
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve the toughness, heat resistance and adhesion to a base material comprising, e.g. aramid fibers in a molded article by reacting essential constituents comprising a phenol compound, an aldehyde, an aromatic amine and a xylene glycol, etc.
SOLUTION: A phenolic resin condensate is obtained by subjecting at least one phenol compound (A) comprising, e.g. phenol, catechol, resorcin, hydroquinone, bisphenol A or naphthol, at least one aldehyde (B) comprising, e.g. formaldehyde, paraformaldehyde or benzaldehyde, a component (C) comprising at least one xylene glycol, such as p-xylene glycol dimethyl ether or m-xylene glycol, or at least one derivative thereof, in an amount of 10-170 pts.wt. based on 100 pts.wt. component A, and an aromatic amine (D) comprising, e.g. phenylenediamine, aniline or aminonaphthalene, in an amount of 2-100 pts.wt. based on 100 pts.wt. component A to addition condensation in the presence of an acid catalyst and a metal salt catalyst. If necessary, a curing agent is added to the phenolic resin condensate.
