Description

DETAILED DESCRIPTION OF THE INVENTION The unexploded FJA relates to a method for manufacturing a laminate, and more particularly, to a method for manufacturing a laminate in which a surface material is laminated and bonded onto a base material impregnated with a resin.

Conventionally, to manufacture a laminate, a resin-impregnated T-coat base material and an adhesive-coated surface material are laminated, and then,
The laminate was placed on a conveyor and heated while being conveyed horizontally to cure the resin and dry the adhesive. Therefore, there was a problem in that the smoothness of the product was affected by the smoothness of the conveyor belt surface. In addition, when bonding the surface material to both sides of the base material, the surface material on one side of the base material is in contact with the conveyor belt, and the surface material on the other side is not in contact.
In addition, because the presence of the belt creates a difference in the heating conditions for both surface materials, the resistance applied to each surface material during movement of the base material differs, which causes the problem of wrinkles on the product surface. there were.

The present invention was made in view of the above-mentioned points, and its main purpose is to improve the smoothness of the belt surface of the Cosiveer by conveying it without using a Cosiveer when heating the laminate. The purpose is to ensure that the smoothness of the product is not affected.
Another objective is to make J5 so that even when the surface material is bonded to both sides of the base material, both surfaces are heated under the same conditions so that wrinkles do not occur on the product surface. be.

Embodiments of the present invention will be described below based on the drawings. The method for manufacturing a laminate according to the present invention is a method for manufacturing a laminate in which a surface material (2) is laminated and bonded on a base material fil impregnated with a resin. A long substrate fl) made of cloth or the like is conveyed along the longitudinal direction and soaked with resin^, and then the (B) surface material (2) coated with adhesive is applied to the base material 11), the surface Kf! IF spring glue:
(After Q, the laminate (3) of the base material 111 and the surface material (2) is conveyed along the vertical direction and then heated to harden the resin and dry the adhesive. In this example, the surface material (2) is copper foil, and a method for manufacturing a printed wiring board is exemplified. Figure qg1 is a block diagram showing a schematic number of the manufacturing process, and the basic Material (1
), kraft paper or cloth is used. Base material fil #i is formed by laminating a plurality of raw sheets (4). Each raw sheet (4) is wound into a roll and supplied in the form of one long body, and is sent out along the longitudinal direction. into which the resin is easily impregnated. Next, the base sheet (4) is impregnated with K using each resin such as Hollyester Sievo+Siν or Phenol 41 Fat Relyl (to). and are overlapped to form the base material ill.On the other hand, the surface material (2
) is supplied as a long body like the base material il+, and is sent out along the longitudinal direction.In this example, the surface material (2) is a copper foil, and the surface material (2) is a K silicon sheet. (4) An adhesive having good adhesion to the resin impregnated in step (4), such as an evo-cow adhesive, is applied. The surface material (2) coated with adhesive and the base material impregnated with resin are pressed and laminated by passing between a pair of laminate wheels (6). If (2) is considered 9 times, the second
It goes without saying that the surface material (2) is conveyed from both sides of the base material fi+ in the thickness direction as shown in the figure. In addition, at this time, it is not always necessary to supply the same type of surface material from the open side; for example, supply copper foil from -10,000 and base material +11 from the other side.
A protective film may be provided to protect Table III.

The base material (11) formed by passing through the sanate roll (6)
and the surface material (2) (3) and the surface material (2).

Usanate 0-ru (
6) and a pair of drawer D-rules (8) disposed on the exit side of the Shinia furnace (7) are arranged above and below, and the 81-layer body (31 is supported in the vertical direction) It is transported along the

In Fig. 2, the body (3) is being conveyed from above to the bottom, but it is shown that the body (3) is being conveyed from the bottom to the top (y
It's okay to do that. In addition to applying heat to the intermediate furnace (7), the curing of the resin may be promoted by irradiating electronic beams from a beam irradiator (9).

One piece of cypress (3), which has undergone the treatment of resin facilitation and adhesive drying, is cut with a forceps cutter (!o1) to form a product (111) (1).

As described above, the present invention heats the laminate of the base material and the surface material while being conveyed along the entire vertical direction to cure the resin and dry the adhesive. This method has the advantage that there is no need to convey the product along the conveyor belt, the product is not affected by the smoothness of the conveyor belt surface, and the smoothness of each product is improved. First, since a conveyor is not used, even if the surfacing material is bonded to both sides of the base material, there is nothing that comes into contact with both surfacing materials during heating, and both surfacing materials are fed at the same speed, and both surfaces are This method has the advantage that the materials are heated evenly, and the laminate does not wrinkle during heating, making it possible to provide a product of excellent quality. Furthermore, since the laminate is conveyed vertically during heating, a Shinia furnace is required for heating! It has the advantage of being able to be installed in a small area, reducing the installation area and making effective use of space within the factory.
