Abstract

PURPOSE: To obtain a molding material having excellent moldability and storability and capable of giving moldings free of generation of ammonia gas, by adding hexamethylenetetramine to a mixture of novolak type phenol resin and resol type phenol resin.
CONSTITUTION: One hundred pts.wt. phenolic resin, consisting of 40W65wt% novolak type phenol resin (A) and 60W35wt% solid resol type phenol resin (B), is mixed with 3W10pts.wt. hexamethylenetetramine, together with, as needed, a filler, a mold releasing agent, and a colorant, and the mixture is well mixed and ground to obtain a phenolic resin molding material. The resin (A) is obtained by the reaction of a phenol (e.g., phenol or cresol) and an aldehyde (e.g., HCHO) in the presence of an acid catalyst, and also the resin (B) is obtained by the reaction of both reactants in the presence of an alkaline catalyst.
