2. Description of the Related Art Conventionally, a phenol resin has been widely used as a molding material by mixing and kneading it with a base material, a plasticizer, a coloring agent, a release agent and the like. The phenol resin molding material thus obtained is a material having well-balanced heat resistance, mechanical properties and electrical properties. Recently, due to the expansion of its applications, it has been applied to various electric parts, structural parts, automobile parts and the like, and it is necessary to further improve the heat resistance, mechanical characteristics and electric characteristics. Further, it is required to be an ammonia-free material for the structural reason of incorporating the parts.

Asbestos has been compounded and used so far in phenol resin molding materials which satisfy such many characteristics. Asbestos has excellent heat resistance, electrical properties, and mechanical strength, and when used in combination with a conventional resole-type resin, it provides well-balanced properties, so it was used as a suitable filler. However, recently, the use of asbestos is prohibited because it deteriorates the working environment and is harmful to the human body. For these reasons, various means and methods have been studied as an asbestos-free material, but the combination of wood flour, pulp, and inorganic filler is inferior in heat resistance, and when cured with hexamine, Although it has excellent electrical characteristics and mechanical strength and a good balance of characteristics, it has a drawback that it is not ammonia-free. From these things, asbestos-free,
There has been a demand for the development of a phenol resin molding material that is ammonia-free and has a well-balanced property.
