Abstract

PURPOSE:To obtain the above resin-sandwiched metallic sheet the end parts of which are excellent in the moldability and the central part being excellent in the vibration damping property and the rigidity, while the metallic sheet having a thick resin in central part is surely obtained by a method in which in the central in width direction of a pick up roll, a depression is formed, and by this roll, the resin with which the sheet is coated is picked up on a coater roll, and then the metallic sheet is coated with the resin. CONSTITUTION:The resin e.g., polyeater resin at 23-25 deg.C with 1900-3000cPs of viscosity on a plate 4 is picked up on a coater roll 5 by the pick up roll 3 in which the central part in width direction to a metallic sheet 1 is formed into a depression 10, and while the resin on the coater roll 5 picked up outside of the width of the metallic sheet 1 is removed, one surface of the metallic sheet 1 is coated with resin. Both ends of the sheet remain adhering to the surface of said roll. In the central part in width direction in this state, the resin may be picked up thicker than the resin picked up on both-ends by bringing the sheet in contact with the rolling coater roll, and the coating on the metallic sheet is also achieved correspondingly to this picked up distribution.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for manufacturing a resin sandwich type metal plate.

[Prior art and problems to be solved] It is common to manufacture a resin sandwich type metal plate by applying resin to one side of a metal band (plate) and press-bonding another metal band (plate) to the coated resin surface. Are known. (Unexamined Japanese Patent Publication No. 61-40
(Refer to No. 150, etc.) However, in such metal strips (plates), resin is interposed in a uniform thickness in the width direction of the metal strip, and for example, if the resin thickness is increased to improve vibration damping properties, etc. Naturally, the thickness of the metal band becomes uniform in the width direction as well. Generally, when welding this kind of resin sandwich type metal strip, those in which both ends of the metal strip are welded have the disadvantage that the thicker the resin, the worse the weldability, as mentioned above. It is.

The present invention has been made in order to advantageously solve these drawbacks and provide a method for manufacturing a resin sandwich type metal strip that can improve vibration damping properties and rigidity without deteriorating weldability.

[Means for Solving the Problems] The gist of the present invention is to pick up resin onto a coater roll using a pick-up roll having a concave central portion in the width direction, bring the coater roll into contact with one side of a metal strip, A method for manufacturing a resin sandwich type metal plate, characterized in that a resin is applied to one side of the metal band while pressing both ends of the other side of the metal band at the coater roll position, and then the metal band is crimped onto the resin surface, and A pick-up roll having a concave width-wise central part picks up the resin onto a coater roll, brings the coater roll into contact with one side of the metal strip, and while pressing both ends of the other side of the metal strip at the coater roll position, removes the resin from the coater roll. The method is characterized by applying resin to one side of the metal while pressing one end of the inlet and outlet rolls of the other side of the coater roll against one end and the other end of the metal strip, and then crimping the metal strip onto the resin surface. This is a method for manufacturing a resin sandwich type metal plate.

That is, in the present invention, as described above, the central part in the width direction of the pickup roll is formed in a concave shape, the resin to be applied is picked up by this roll onto the coater roll, and the resin is applied to the metal band by the coater roll.
As shown in Figure (A), resin 2 is applied in steps on one side of the metal strip 1 so that the layer is thicker at the center in the width direction than at both ends, and then as shown in Figure 1 (B). Another metal band 1a is crimped onto the surface of the resin 2, and the metal band 1. Ia is a resin sandwich type metal plate having two resin layers that are thicker at the center portion in the width direction than at both end portions. Further, as shown in FIG. 2(A), resin 2 is applied on one side of the metal strip 1 in a curved shape so that the center part in the width direction is thicker than both ends, and then as shown in FIG. 2(B). As shown, another metal band 1a is crimped onto the surface of the resin 2, and the metal band 1. This is a resin sandwich type metal plate having a thicker layer of resin 2 at the center portion in the width direction than at both end portions.

Therefore, the length of the recess formed in the widthwise central part of the pickup roll is, for example, when the resin at both ends in the widthwise direction of the metal band is made thinner than the central part to improve weldability.
Concave portions are formed from inside approximately 100111I11 from both ends of the metal band, and the depth thereof varies depending on the thickness of the resin layer to be applied, but for example, the depth is 130μ or less at both ends and 130μ or less at the center.
When the resin layer has a thickness of more than 0 to 170μ, the thickness is 0.05 to 0.
] Omm is sufficient.

In other words, the resin remains in the recess formed in the center of the pick-up roll, and the resin remains attached to the roll surface at both ends.By rotating in contact with the coater roll, the resin remains in the center in the width direction. The resin can be picked up thicker than at both ends, and the metal strip can be coated according to this pickup distribution.

[Example code] Next, embodiments of the present invention will be described with reference to the drawings.

(Example 1) In FIGS. 3 and 4, metal strip 1 (copper strip 2 0.45
mm thickness, width 887111Q+) with a concave center part in the width direction 10 (depth 0.06 mm from 140 mm inside the metal band both ends)
The resin 2 (viscosity 1900-3000c, ps,
A polyester resin with a temperature of 23 to 25° C. is picked up on the coater roll 5, and while the resin on the coater roll 5 picked up outside the width of the metal band 1 is removed by the doctor 6 placed at both ends of the coater roll 5, the metal band is removed. Apply resin to one side of 1.

On the other hand, at the coater roll 5 position on the other side of the metal strip 1, both ends of the metal strip 1 are pressed by the presser roll 7, and the entry side roll 8
and exit roll 9 (both 350 mm from the coater roll position)
mII+), the metal strip 1 is guided and threaded (10 m/min), and the center part 400n++a in the width direction of the metal strip is passed.
160~180μ thickness, 100~130mm at both ends
A 130 μ thick resin was applied, and then another metal strip (steel strip: 0.30 mm thick, 887 mm wide) was crimped onto the surface of the coated resin to produce a resin sandwich type metal plate as shown in Fig. 1 above. .

(Example 2) When applying resin to one side of the metal strip 1 under the same conditions as in Example 1, as shown in FIG. While pressing one end of the metal strip 1 with one end of the metal strip 1 and pressing the other end of the metal strip 1 with one end of the exit roll 9, the resin is applied to one side of the metal strip 1 with the coater roll 5 as shown in FIG. Apply, both ends 100-130
After coating the resin to a thickness of 160 to 180 μ at the center, another metal strip (steel strip: 0.3 mm thick, 7 mm aa width) was crimped onto the resin surface to produce a resin sandwich type metal plate.

[Effects of the Invention] As a result, according to the method of the present invention, a resin sandwich metal plate or metal plate that is thin at both ends in the width direction and thick in the center can be reliably obtained, and the edges can be welded. Excellent effects can be obtained, such as an excellent metal plate that can be used as a resin sandwich type metal plate, etc., which has excellent vibration damping properties and rigidity in the central part.
