PHENOL RESIN MOLDING MATERIAL AND MOLDING

摘要

PROBLEM TO BE SOLVED: To obtain a phenol resin molding material for forming a molding having a slight dimensional change caused by a dynamic load and a heat history during or after component processing. SOLUTION: The phenol resin molding material is obtained by blending a phenol resin with a filler. The blended amount of the phenol resin is 25-35 mass% based on the total of the molding material. The blended amount of a resol type phenol resin in the phenol resin is 2-15 mass% based on the total of the phenol resin. An acrylic acid alkyl ester-based material or a methacrylic acid alkyl ester having a structure represented by formula (1) or formula (2) is used as the filler. COPYRIGHT: (C)2007,JPO&INPIT
