There are the following methods for manufacturing metal-clad laminates such as copper-clad electrical insulating boards. That is, unsaturated resins having unsaturated bonds such as unsaturated polyester resins, diallylphthalate resins, vinyl ester resins, etc. are diluted with vinyl nitrate (crosslinking agent), and a polymerization initiator is further added to form unsaturated resins. A resin-impregnated base material is created by making phenol and impregnating it into paper or other base material. Next, multiple layers of this resin-impregnated base material are stacked,
Furthermore, a metal-clad laminate is produced by overlaying adhesive-coated copper foil or other metal foil on at least one of the front and back surfaces of this laminate, and then heating it under no pressure. In this method, continuous production is possible because the laminate is heated and cured without pressure, without applying heat and pressure to cure the laminate one by one. In addition, when producing unsaturated resin pheno, the unsaturated resin is not diluted with a solvent, but is diluted with a crosslinking agent to create pheno, so there is no need to use a solvent, which is advantageous in terms of resource saving, etc. ing.

Not limited to this method, when attempting to continuously manufacture metal-clad laminates, it is possible to pre-cure the adhesive layer provided on the metal foil, or to fully cure the synthetic resin component of the resin-impregnated base material. After the main curing, the product is necessarily subjected to post-curing (after-curing). Conventionally, this was done by using hot air as a heat source, which took several minutes to several tens of minutes for curing, which was one of the reasons for hindering speed improvements in the production line.

きた。
As a result of the curing time required, the problem arises that the space occupied by the thermosetting furnace increases. For example, when making double-sided copper-clad laminates, the building for the large curing furnace is three stories high, and the effective height of the factory building is It was even several meters long. Since the energy efficiency is poor and the heating load on the furnace body reaches 20 to 30 inches, there are also problems from the point of view of energy saving. Furthermore, heat curing causes the temperature of metal foil such as copper foil to drop significantly, which not only impairs the surface smoothness of the product, but also causes quality problems such as problems with heat resistance.

The inventors have made various efforts to solve these problems. As a result, it has been found that these problems can be solved by curing the synthetic resin component by irradiation with electron beams. When irradiating with an electron beam,
There is a scanning method in which electrons generated from a cathode are accelerated through a linear accelerator so that they have the necessary energy, and then are swung to produce the necessary width for processing. There is a method called the curtain type, which uses rain to illuminate the area. Among these, the curtain type type requires a low voltage and is convenient, but its low energy limits the irradiation depth and thickness, which limits its uses.

For example, when using a 7501 cV scanning device, even a 1.6 mm thick product (9 steel foils on one side, 5 layers of paper) can be cured. Moreover, the curing speed becomes faster and the curing time can be shortened. Therefore, the installation space (height) of the curing furnace is reduced to about half, the line speed is improved, and the productivity of laminated plates is increased. Energy efficiency increases, making it possible to save energy. Since the temperature rise of copper foil and other metal foils is extremely small, the adverse effects of heat on the dimensions and shape of the laminate, such as foil elongation and wrinkles, are reduced or eliminated. 1 - Therefore, the surface smoothness and other quality of the product,
, I: can be calculated. Conventionally, it was necessary to add a reaction initiator to adhesives, but electron beam irradiation eliminates the need for it, which not only extends the life of the resin, but also simplifies equipment and operations, improving workability. When producing a single-sided metal-clad laminate, electron beam irradiation is also used to coat the resin gel coat on the release film that is stacked on the back side. Electron beam irradiation is also effective when making decorative boards.
