性樹脂パウダーをフェノール樹脂(Industrial Application Field) The present invention relates to a method for producing a paper phenolic resin-like blank board that has excellent punching workability and dimensional stability, and is less warped and twisted. (Prior art) Paper phenolic resin laminates and copper-clad laminates that are generally used as printed circuit boards are required to have electrical properties, thermal properties, and mechanical properties, but also from the processing side of the laminates. As a result, it is required to have good low-temperature punching workability, low warping and twisting, and excellent dimensional stability. Traditionally, as a method for improving these properties, paper phenol laminates were obtained by impregnating a mixed paper base material with phenolic resin varnish and inorganic fillers such as titanium white, clay, talc, and aluminum hydroxide, then drying and molding. ing. (Problems to be solved by the invention) However, since the filler is inorganic, it promotes wear of the punching pin in terms of punching processability, and the interlayer adhesion with the resin is weak, causing interlayer delamination. Cheap. Furthermore, depending on the type of inorganic material, the transparency of the laminate may be impaired. The present invention has been made in view of these points, and provides a method for manufacturing a laminate that has excellent punching workability, does not cause glabellar peeling, and has a good appearance. (Means for Solving the Problems) The present invention consists of impregnating a gold paper base material with a phenolic resin varnish containing 5 to 40% (same as less than 1% Fi) of heat-resistant thermoplastic resin powder as a filler and drying it. The method is characterized in that prepreg is obtained by heating and pressurizing the required number of prepregs. In other words, the present invention uses heat-resistant thermoplastic resin powder produced by a normal manufacturing method as a phenolic resin.

aminosilane type, silane type, etc.) f: 15 for filler
Phenol resin-impregnated paper (prepreg) obtained by impregnating a paper base material with ~5% by weight of phenolic resin varnish and drying it.
It is characterized by laminating a required number of sheets and molding them under heat and pressure in a molding press. The thermoplastic resin used preferably has a melting point or thermal deformation temperature of 160° C. or higher from the viewpoint of heat resistance, and preferably 200° C. or higher from a practical level. For example, polyetherketone, polyetherimide,
Polyetherketone or the like is used. The particle size of the powder can be as fine as 25 mesh or more, but 40
~600 meters is preferred. In the present invention, the filler t
- The reason for limiting the amount to 5 to 40% is that if the amount added is less than 5%, satisfactory results in punching workability and dimensional stability cannot be obtained, and if it exceeds 40 fft amount %, phenol The viscosity of resin varnish is high, and the workability and impregnation properties are poor, which has a negative impact on custom-made laminates, but the addition amount of 5
~ 40311 (Child%) does not have this drawback and the effect of the present invention cannot be achieved.Also, if the phenol resin is mixed with a silane-based coupler (aminosilane, epoxysilane, etc.) for the filler (15~5%). The present invention also has similar effects on other thermosetting resins (polyester resins, epoxy resins, melamine resins).Example 1 Phenolic resin (tung oil modified-Jl, 50% ): 100 parts polyether length sulfone resin powder: 5 o 31 ik part varnish set M, using a solvent to reduce the varnish resin content to 45 to 5
0%, impregnated into kraft paper, dried, and adhered to Yanagi Ginkaku 4
A paper impregnated with 8-52% phenolic resin was obtained. The required number of sheets were stacked and molded at a pressure of 150 kg/U and a temperature of 165° C. for 60 minutes to create a single-sided steel-clad laminate with a thickness of 1.6 mm. Example 2 Phenol resin (modified amount of tung oil 50%) = 100 parts by weight Tetrafluoroethylene resin powder: 1.6 m using 55 parts by weight of varnish composition, other than Example 1
A single-sided steel-clad laminate was prepared. Comparative Example 1 The filler was not added in Example 1, except for Example 1.
All 1.61 single-sided ring-strapped laminates were prepared according to the method. Comparative Example 2 Phenol resin (modified amount of tung oil 50%) = 100 parts by weight Burgess clay: 5s'Mf#W15
The varnish composition was 1°611 according to Example 1 except for the following.
A 1111 single-sided copper-clad AT laminate was prepared. Table 1 shows the performance of the single-sided copper-clad laminates obtained in Examples and Comparative Examples. As is clear from the results in Table 1, the examples of the present invention have excellent punching workability and dimensional change rate, but Comparative Example 1 without filler has excellent punching workability and dimensional characteristics. Comparative Example 2 in which the material was added had problems in heat resistance, punching workability, wear of the punching pin, and some of the above-mentioned properties, and could hardly be said to be satisfactory. d-F Kinpaku (Effects of the Invention) As revealed above, paper phenolic resin laminated IO boards and copper-clad laminates using heat-resistant thermoplastic resin powder as a filler have excellent punching workability and dimensional stability. Excellent and electrical
Good mechanical properties.
