いる。2. Description of the Related Art A phenol resin binder for various base materials
Molding the material containing the, using a heating mold, for example, the production of composite building materials by dry pressure molding, the production of board core material for interior materials, the production of mold for shell mold,
It is carried out during the production of a phenol resin molded product. In these productions, attempts have been made to improve the releasability from the mold from the viewpoints of reduction of defective rate and workability. Among them, the board core material for the interior material, which is based on the fiber material, has various needs regarding the shape, quality, performance, etc., so that the die has a curved surface with a complicated and deep drawing. Is often adopted. Since the board core material is composed of highly entangled fibers and a resin binder with high adhesiveness, the mold releasability at the time of molding is poor, which hinders automation of the process and causes a defective molding rate. It has the problem of becoming expensive.

るとはいいがたい。The use of a phenol resin binder in the production of molded felt is known from Japanese Patent Application No. 2-090179, but no mention is made of improving the releasability. In general, as a method for improving mold releasability at the time of molding, a method of applying or spraying a mold release agent such as fluorine-based or silicon-based mold, a method of adding a fatty acid or a metal salt thereof to a binder, etc. are known. However, in the former case, it is necessary to spray the release agent frequently in order to enhance the release property, and in the latter case, not only the compounding amount is limited due to the problem of practicality in each application, but also the release effect is obtained. I can't get enough. There is also a method of using both in combination, but it cannot be said that this is sufficiently effective.
