Conventionally, when joining the outer panel on the surface of the foam sheet,
Taking an example of a heat-insulating molded ceiling panel inside an automobile body,
As shown in FIG. 1, a thermofusible film 3' is placed on top of a foamed sheet 1' (for example, a foamed polyethylene sheet laminated with PVC leather).
Furthermore, an outer panel 2' (for example, cardboard, resin board, Dilarc, etc.) was placed on top of this and hot pressed. Needless to say, the upper and lower molds are heated. That is, due to the heat conduction through the foam board 1' and the outer panel 2' due to this heating, the heat-melting film 3' sandwiched between them is heated and melted.
They were joined together. It takes a relatively long time to melt the film by heat conduction heating.
This was a major hindrance in raising the production pitch.

An object of the present invention is to provide a method for bonding a foamed sheet and an outer panel under pressure at room temperature during the open time by dispensing a foamed hotmelt, and to provide a product thereof.

Next, the method of using the foamed hotmelt used in the present invention will be explained.Before that, the results of an experiment using a general type hotmelt instead of the foamed hotmelt will be described.
In conclusion, when a general type hot melt was used, the adhesive strength was relatively low. The reason is presumed as follows. The general type hot melt 9 sprayed onto the surface of the foam material 5 (FIG. 2) flows down into the porous chambers 5a, 5b, 5c of the foam material 5 within a short period of time (FIG. 2).
As seen in FIG. 3, the general hot melt layers 9a, 9 remaining on the surface of the foamed material 5
b, 9c... become thinner (this state can be confirmed visually). This thinning allows cooling and solidification to proceed in a short time. This reduces the adhesion effect in the next step, when the adhesive is brought into contact with the object and pressurized.

Next, an experiment was conducted using a foamed hot melt instead of the general type hot melt. As a result, satisfactory adhesive strength was obtained. The reason for this is thought to be as follows. As shown in FIG.
Foamed hot melt 10 dispensed on the surface of
Because of its relatively low specific gravity and low fluidity characteristic of foamed fluids, it forms a thick layer and lightly rests on the surface of the foamed material 5.
(This condition can be clearly confirmed visually).
Furthermore, due to the relatively long cooling and solidification time (i.e. long open time), which is also a characteristic of foamed hotmelt, this layer has a relatively long cooling and solidification time (i.e., a long open time), so that by the time it comes into contact with the object in the next step and is pressurized, the foamed hotmelt is is in a molten state and fully exhibits its adhesive action. However, foaming hot melts also take a certain amount of time (approx.
After 20 minutes, the foamed hotmelt penetrates into the porous chambers and the surface layer becomes thinner, as in the case of the general type hotmelt (Fig. 3).

The above-mentioned foamed hot melt is a Japanese patent registration number 1380841 (Special Publication No. 1380841 (Special Publication No.
3350), 1282090 (Special Publication No. 60-4228) and
It is made using the equipment according to No. 59-182825, and its contents can be briefly explained as: unvulcanized rubber-based, saturated polyester-based, polyamide-based,
Polyolefin-based and polyolefin-based copolymers or modified products thereof, in which air or a gas such as N 2 or CO 2 is mixed in the form of countless closed cells in these hot-melt adhesives. Naturally, their volumes are expanded by 1.5 to 5 times. These characteristics include not only maintaining the original adhesive properties, but also reducing the amount of adhesive used as a raw material due to a decrease in specific gravity, decreasing the apparent viscosity under high pressure in the applicator,
After adhesion, air bubbles may rapidly expand and enter slits, reduce fluidity, thin the adhesive layer due to pressure bonding and expand the bonding area, shorten the set time, and prevent problems such as porous surfaces and Adhesion improves adhesion to rough surfaces, expands low-temperature applications by rapidly cooling the surface, increases elasticity, improves sealing performance, extends open time during other operations, reduces overall costs, etc. It has many advantages in terms of processing.

Next, I would like to explain in more detail the adhesive effect of the above-mentioned foamed hotmelt on open cell portions on porous surfaces.

ある。
Originally, the adhesion effect on porosity of the conventional general type (solid type) hotmelt and the foamed type hotmelt used in the present invention are very different. Regarding the former, as explained in Figures 2 and 3 above, it easily penetrates into the open cells on the porous surface due to gravitational action, but this causes trouble. On the contrary, the layer of solid hot melt in the convex part of the porous part becomes thinner9.
a, 9b, 9c, ..., and it becomes easier to solidify by cooling,
As mentioned above, the adhesive strength gradually decreases.

On the other hand, when the present foamed hotmelt is applied onto a porous surface, as briefly explained above, the specific gravity of the foamed hotmelt is a fraction of that of the former at the same volume. Therefore, the influence of gravity is small, and therefore, the layer of foamed hotmelt immediately after dispensing is lightly placed on the porous surface as shown in Figure 4, as in the case of the solid hotmelt described above. There is no thinning in the porous convex portions, and it exhibits a strong adhesive effect with the object to be adhered.

On the other hand, as shown in Figure 4A, when applied to a porous surface, due to the characteristics of the foamed hotmelt described above, immediately after dispensing, the fine bubbles expand rapidly, causing the openings on the porous surface to form. It penetrates deep into the microscopic cell (5a) of the cell (10a),
They dig into each other like a jigsaw puzzle, further enhancing the anchoring effect of the adhesive.

As mentioned above, the foamed hot melt applied in layers on a porous surface has a long open time, both on the same surface and on the object to be adhered, so it is more effective in adhering both surfaces. It is possible to gain strength.

The method according to the invention will be explained with reference to the drawings. Taking an example of a heat-insulating molded ceiling panel in an automobile as before, as shown in FIG. 5, a long foam sheet 11
is supplied to the cold press 16. In a step immediately before supplying the foamed hot melt, the foamed hot melt is sprayed (13) onto the foamed surface 11b of the foamed sheet 11. Immediately after that, the cutter 23 cuts it into a regular length and supplies it between the upper and lower molds 17 and 18 in the room-temperature press 16. At the same time, an outer panel 12' is also supplied above the foamed sheet 11'. After this is set in the appropriate position, the upper mold 18 is lowered (“P”).
The foamed hot melt 13' on the surface of the foamed material 11b', which is sandwiched between the lower molds 17, comes into contact with the outer plate 12' and is pressurized at room temperature. As described above, the foamed hot melt 13' in a molten state adheres to the outer panel 12' while maintaining a relatively thick adhesive layer, thereby obtaining a foamed laminate sheet 11'.

As mentioned above, foam sheets or foam laminated sheets,
In the work of bonding other types of sheet materials onto the surfaces of fibrous sheets, fibrous laminated sheets, etc., the property of the foamed hot melt as a bonding medium according to the present invention to penetrate into minute spaces is utilized. This strengthens the adhesive anchor, maintains the adhesive force to other types of sheet materials to prevent deterioration due to the relatively long open time, saves equipment costs by using room temperature and low pressure type adhesive equipment, and also reduces manufacturing man-hours.
This makes it possible to provide foam sheets at a lower cost due to production efficiency, lower running costs, and overall reduction in production costs.
