に抄き込むことである。2. Description of the Related Art A laminated board is manufactured by impregnating a fibrous base material (paper base material, glass non-woven fabric, glass cloth, etc.) with a resin varnish and drying it to obtain a prepreg. . Defective laminates, scraps, and materials incorporated in discarded products (hereinafter collectively referred to as waste laminates or simply laminates) are not reused at this time and are treated by combustion or landfill. . However, in order to reduce waste and effectively use resources,
Recycling has come to be desired. A possible means for recycling the waste laminate is to mix the crushed material of the waste laminate into a resin varnish or to cut it into a fibrous base material.

るものである。However, when the powder of the laminated plate is added to the resin varnish for impregnation, the powder of the laminated plate does not enter the base material and is biased to the resin layer on the surface. Then, they fall off during handling of the laminated plate, which deteriorates the working environment. Also, the powder that has fallen off adheres to the surface of the copper foil,
After pressure molding, dents and scratches due to powder are generated on the surface of the copper foil. When the powder of the laminated board is made into the fibrous base material, such a drawback can be solved, but the powder of the laminated board may interfere with the adhesion between the resin and the base fiber and may be peeled off during the punching process. In any case, the addition of the waste laminate powder reduces the quality of the laminate. An object of the present invention is to recycle a waste laminated plate without deteriorating the quality of the laminated plate.

これらは、単独でも、併用でもいずれでもよい。The plastic resin is an uncured thermosetting resin or a heat resistant thermoplastic resin. The uncured thermosetting resin includes solid resol resin, solid novolac resin, and epoxy resin. Examples of the heat-resistant thermoplastic resin include polyether sulfone, polysulfone, polyetherimide, polyamideimide, oxybenzoyl polyester, polyetheretherketone, polyphenylene sulfide, liquid crystal polyester, and fluororesin.
These may be used alone or in combination.

い。The particle size of both the laminated plate powder and the plastic resin powder is preferably 0.5 to 50 μm. If it is less than 0.5 μm, it is difficult to hold it between the fibers when it is made into paper,
If it exceeds m, it is difficult to make paper. The compounding weight ratio is 10 to 30% of laminated plate powder (the same applies hereafter to the weight ratio) and 10 to resin powder.
40% and 30 to 90% of paper or glass fibers are preferred.
If the powder of the laminated plate and the powder of the plastic resin are increased, it is difficult to form a sheet. Further, at the time of papermaking, a paper-strengthening agent that serves as a binder such as water-soluble melamine, and a coupling agent such as aminosilane or epoxysilane may be added, if necessary. The use of the coupling agent improves the affinity between the paper fiber or glass fiber and the laminated plate powder or the resin powder. The required number of paper base materials and glass non-woven fabrics thus obtained may be heated and pressed as they are to form a laminated plate, but a phenol resin, an epoxy resin, a polyester resin may be impregnated and dried to obtain a prepreg. Several sheets are stacked and heated and pressed to form a laminated plate. At this time, a copper clad laminate is obtained by simultaneously heating and pressing copper foil. The copper foil may have an adhesive.

和性が向上するためである。[Function] The powder of the plastic resin acts to bond the powder of the laminated plate and the fiber of the base material to each other, and punching workability, drilling workability,
Heat resistance is improved. This is because the powder which has been hardened in advance is uniformly dispersed in the fiber, and the affinity between the fiber and the powder is improved.
