ノシランおよびエポキシシランの少なくフ とも一方。In recent years, phenolic resin molding materials have been reviewed in order to reduce weight, rationalize manufacturing processes, and reduce costs by replacing metal materials with plastic materials. Generally, phenolic resin molding materials include reinforcing materials,
Organic materials such as wood flour and pulp, and inorganic materials such as asbestos, glass fiber, calcium carbonate, talc, and mica are used as fillers. Among these materials, organic substances such as wood flour and pulp are not used as molding materials for manufacturing substitutes for metal parts that require heat resistance, and in such cases,
Inorganic substances are mainly used. Although molding materials using inorganic materials can produce molded products with higher heat resistance than molding materials using organic materials such as wood flour and pulp, they are still not satisfactory. When mechanical strength is required for molded products, glass fibers are used as reinforcing materials and fillers. However, when glass fibers are used, metals such as cylinders are abraded heavily during molding of the molding material, so at present they are not used to the extent that they can sufficiently improve the mechanical strength of molded products. As a result of intensive research to obtain a molding material that can produce molded products with high heat resistance and mechanical strength, and that causes extremely little metal abrasion in cylinders, etc. during molding, the inventor found that reinforcing materials,

る。That is, the treatment agent (4) was applied to mica in an amount of 0.5 to 5.
0% by weight (hereinafter abbreviated as "%") and a methanol diluted solution of processing agent (B) (concentration 2 to 3%). 0.5-5.0%
The mica is uniformly sprayed and rolled at room temperature until the average particle size of the mica becomes 20 to 60 mesh (roll treatment). By doing this, the mica is exfoliated, and the treatment agents (A) and (B) are applied to the exfoliated surface and permeate therethrough, making it possible to exhibit the effect of improving heat resistance and mechanical strength. This heat resistance and mechanical strength improvement effect can only be exhibited by using the processing agent in combination with (B). In other words, if only the treatment agent (4) is used, the effect of improving mechanical strength may be exhibited, but the effect of improving heat resistance will not be exhibited. On the other hand, if only the treatment agent (B) is used, the effect of improving heat resistance may be exhibited, but the effect of improving mechanical strength will not be exhibited. Therefore, by using both in combination, the effects of both can be exhibited. And processing agent (4)
If the amount used is less than 0.5%, the effect will be small, and 5
%, no further increase in effect is observed. Therefore, considering cost, effectiveness, etc., processing agents (
As mentioned above, the amount of treatment agent (4) used is usually selected so that the amount of treatment agent (4) is 0.5 to 5.0% based on mica. In addition, if the amount of the methanol diluted solution used in processing agent 8 is less than 0.5%, the effect will be reduced, and if it exceeds 5%, the bottom and side surfaces of the secondary
The kneaded material adheres to the screws and the continuous workability deteriorates. Therefore, taking these into consideration, processing agent (B)
As mentioned above, the amount of methanol diluted solution used for treatment agent (B) is usually 0.00% for mica.
It is selected to be 5 to 5.0%. The phenolic resin molding material is treated with the treatment agent (A), (
It is manufactured in a conventional manner using mica that has been subjected to pressure shearing treatment (hereinafter abbreviated as "treated mica") together with B).
