It consists of a continuous process such as laminating, curing continuously, and cutting.

となる。The glass nonwoven fabric used in the continuous method has a lower density and a higher porosity than glass cloth or the like. Therefore, in the process of impregnating a glass nonwoven fabric with a curable resin liquid, stacking and combining the impregnated base materials, and laminating, if the time to transport the base materials is long, the curable resin liquid impregnated with the impregnated base material may drops from the base material and dries up, the air embedded in the incompletely impregnated area with the resin liquid expands, and the crosslinking monomer gas collectively expands, causing the cured product to swell and bubbles. Since voids such as these remain, they cause a decrease in properties such as heat resistance. Increasing the viscosity of the curable resin liquid improves the retention of the curable resin liquid in the glass nonwoven fabric, but it has disadvantages such as longer impregnation time and larger equipment space, and high viscosity curable resins The liquid delivery system becomes complicated.

等の特性を低下させる原因となる。To implement the present invention, the method of impregnating a glass nonwoven fabric with a curable resin liquid is to apply an appropriate amount of the curable resin liquid to one side of the base material and impregnate it, or to harden it. There is a method of immersing the base material in a liquid resin to impregnate it from both sides, but any method may be used. The time required for conveying the impregnated base material, combining it, and laminating the cover sheet and/or metal foil is 5 to 120 seconds, more preferably 10 to 90 seconds. If the impregnation time is less than 5 seconds, the space for equipment in the step of combining the impregnated base materials and laminating the cover sheet and/or metal foil is too small, making it difficult to operate. At the same time, the impregnation of the curable resin liquid into the base material is poor, and the product after curing swells and voids such as bubbles remain, which causes a decrease in properties such as heat resistance.

め、硬化後の製品に気泡等のボイドが残り、耐熱性等の
特性を低下させる原因となる。In addition, if the impregnation time exceeds 120 seconds, the equipment needed to impregnate the base material with the curable resin liquid and embed the material will be expanded, or the transportation of the base material will become complicated, resulting in poor operability. . At the same time, the retention of the curable resin liquid on the base material deteriorates, and voids such as air bubbles remain in the cured product, which causes deterioration of properties such as heat resistance.

〜１０ボイズであり、これは主に硬化性樹脂液の種類、
架橋用単量体の種類、量または該樹脂液に充填する無機
充填材の種類、形状、量等による。The impregnation and retention properties are influenced by the viscosity of the curable resin liquid and the basis weight of the glass nonwoven fabric. That is, the lower the viscosity of the impregnating resin liquid, the faster the impregnation speed, but on the contrary, the retention of the resin liquid becomes worse and resin wilt is more likely to occur. At this time, the viscosity of the resin liquid is 0.1 to 15 poise, more preferably 1
~10 voids, which mainly depends on the type of curable resin liquid,
It depends on the type and amount of the crosslinking monomer or the type, shape, amount, etc. of the inorganic filler filled in the resin liquid.

、樹脂枯れによる気泡が製品に発生する。Both glass paper and glass mat have a basis weight of 1
0 to 200 g/rd, more preferably 20 to 10
0 g/rd is passing through. In general, glass nonwoven fabrics have a small density (thickness is determined approximately in proportion to basis weight. In a virtually pressureless continuous manufacturing method, the thickness of glass nonwoven fabrics corresponds approximately 1:1 to the thickness of the product plate, and therefore The basis weight of the glass nonwoven fabric is specified because the thickness of the electrical laminate is usually less than l, 5. In other words, when one layer of 200 g/- glass nonwoven fabric is used,
An electrical laminate with a thickness of mm t is obtained. Furthermore, if the basis weight exceeds 200 g/m2, the impregnating properties of the curable resin liquid will be poor, and bubbles will occur in the product due to poor impregnation. On the other hand, if the basis weight is less than 10 g/m2, the retention of the curable resin liquid will be poor, and bubbles will be generated in the product due to the resin drying up.

好ましい。Examples include metal oxides such as silica, alumina, zirconia, titanium dioxide, and zinc white, metal hydroxides such as magnesium hydroxide and aluminum hydroxide, talc, kaolin, mica, wollastonite, and clay minerals. natural minerals,
Examples include insoluble salts such as calcium carbonate, magnesium carbonate, barium sulfate, and calcium phosphate. Inorganic fillers that have a high specific gravity or a large shape tend to settle and are difficult to handle during processing. Further, the unevenness on the surface of the laminate after treatment becomes thick, which causes poor appearance. Therefore, the shape preferably has a small aspect ratio and a grain size of 10 μm or less.

600 parts by weight, more preferably 200 to 50 parts by weight
It is 0 parts by weight. This amount of adhesion is determined in consideration of the balance between the dimensional stability improvement effect of the inorganic filler and the impregnating property of the impregnating resin liquid into the treated substrate.

強し、切断などのトラブルを避けることができる。Although the method of adhering to the nonwoven fabric substrate is arbitrary, the inorganic filler and binder are dispersed in a medium such as water to create a dispersion, the dispersion is supplied to the substrate by dipping, coating, etc., and then dried. This can be done by removing the medium. Nonwoven fabrics, especially glass paper, have a low density (and do not have sufficient mechanical strength such as tensile strength, so problems such as cutting are likely to occur in continuous manufacturing methods. However, by selecting an appropriate binder in this process, tensile strength can be increased. This helps prevent problems such as cutting.
