る。 FIG. 1 shows a continuous method for producing polyurethane foam according to the invention. side wall 24
A continuous manufacturing apparatus for polyurethane foam is known, in which groove-shaped release paper 25 is installed on the front side wall (not shown) and in the conveyor belt 13 running at a constant speed. When the stock solution for forming polyurethane foam is mixed and discharged into this groove-shaped container, the stock solution gradually starts to foam inside the container and becomes a foam.
This is linked to the traveling speed of the groove-shaped container to continuously produce polyurethane foam. In this embodiment of the present invention, when mixing and discharging the stock solution for forming polyurethane foam into a groove-shaped container, the foaming stock solution with the same components is divided into two parts, and the coloring component is mixed more uniformly into one half, and then the foaming stock solution is mixed and discharged. The other stock solution 10 is discharged as it is as a discharge stock solution 11 without mixing any coloring components, and after discharge, both discharge stock solutions 10 and 11 are appropriately mixed and foamed to form a foam 12 having a multi-colored pattern. Form. Since the synthetic resin foam 12 having a multi-colored pattern according to the present invention (hereinafter referred to as the foam according to the present invention) is obtained in this way, the fabric color 14 and the coloring 15 of the foam are applied not only to the outer surface but also to the entire interior. A colored pattern is formed in which the foam is appropriately mixed in the form of flowing stripes or waves, and the colored pattern appears on the outer surface no matter which part of the foam is cut.

ミキシング装置を設ける必要はない。 In this example, the foam is colored in two colors, fabric color 14 and coloring 15.
If a coloring component different from that of the discharge stock solution 10 is mixed into the discharge stock solution 11, the portion will be colored, resulting in two different colored patterns. It is also possible to easily create multicolored patterns by dividing a foaming stock solution of the same component into three or more parts and mixing different coloring components into each part. In addition, the discharge amount of each of the plurality of stock solutions 10 and 11 may be changed to different discharge amounts, and the discharge amount of each of the plurality of stock solutions 10 and 11 may be varied.
By discharging and mixing 1 while moving it from side to side, a variety of colored patterns can be obtained.
The mixing head 1 of the foaming machine includes a mixing chamber 17 having a built-in dynamic mixer 16 and branch nozzles 4 and 5 connected to this mixing chamber 17, and each branch nozzle 4 and 5 having a discharge nozzle 8 and 9. It is connected. Nets 7 and 7' are attached to the tips of the discharge nozzles 8 and 9 as necessary. As shown in FIG. 3, a coloring component introduction pipe 6 is further connected to the branch nozzle 4 connected to the lower part of the mixing chamber 17, and an in-line mixing device 18 such as a static mixer or a dynamic mixer is installed in the discharge nozzle 8. Built-in. A discharge nozzle 9 is connected to the branch nozzle 5 that does not mix coloring components, and there is no need to provide a mixing device in this discharge nozzle 9.

It is possible to mix and eject coloring components with more than one color.

原液が着色され、同時に外部に吐出される。 Since the mixing head of the foaming machine of the present invention has the above structure, the foaming stock solution fed into the mixing chamber 17 through the raw material stock solution introduction pipes 2 and 3 is sufficiently stirred and mixed by the dynamic mixer 16. The mixture is transferred to the branch nozzle 4 and the branch nozzle 5 connected to the lower part of the mixing chamber 17 at a ratio corresponding to the diameter of each nozzle (the third
(indicated by the arrow in the figure). The foaming stock solution transferred to the branch nozzle 5 is directly discharged to the outside through the discharge nozzle 9 and the net 7', and the foaming stock solution transferred to the branch nozzle 4 is mixed with the coloring component fed from the coloring component introduction pipe 6 and discharged. They are mixed together at the nozzle 8, thoroughly mixed by an in-line mixing device 18 built into the discharge nozzle 8, and are discharged through the net 7 to the outside as a foaming stock solution of a single color. The foaming stock solution having the same components mixed in the mixing chamber 17 in this manner is divided into two or more parts, each of which is colored with an arbitrary coloring component, and simultaneously discharged to the outside.

ームしか得られない。 As shown in FIG. 4, the mixing head of the conventional foaming machine feeds the foaming stock solution into the mixing chamber 17 through the raw material stock solution introduction pipes 19 and 20, and at the same time, the coloring component is also delivered through the coloring component introduction pipe 21. The mixture is stirred and mixed by a dynamic mixer 16 and discharged to the outside through a discharge nozzle 22 and a net 23, and only a patternless, single colored foam can be obtained.

る。 In order to obtain a foam with a multi-colored pattern, if a colored component is mixed into the stirred stock solution at the nozzle 22 portion immediately before discharge, a foam with a multi-colored pattern in the form of flow stripes will be obtained, but the colored component will not be sufficiently mixed with the stock solution. As a result, cavities and cracks occur in the colored parts of the foam, making it impossible to obtain a foam that can be put to practical use.

模様の柄も容易に変えることができる。 As described above, the present invention differs from the conventional method for manufacturing multi-colored patterned foams in which raw materials of different colors are prepared separately, mixed and stirred separately, and foamed at the same time. Since it is a product that branches and uniformly mixes the coloring components and foams, it is possible to easily obtain synthetic resin foams with multicolored patterns rich in various variations, and the resulting foams have a uniform density. Become something. Also, by providing a plurality of branch nozzles for mixing coloring components in the mixing head, products with three or more colors can be easily obtained. Furthermore, the pattern can be easily changed by changing the diameter of the branch nozzle.

のミキシングヘツド装置。[Claims] 1. A method for producing a foam having a uniform density, comprising a supplying step, a mixing step, and a foaming step, wherein the supplying step divides a foamable stock solution of the same component into two or more parts. At least one of the divided foaming stock solutions is uniformly mixed with an arbitrary coloring component, and the mixing process is a step in which two or more foaming stock solutions of different colors are separately supplied. 1. A method for producing a synthetic resin foam having a multi-colored pattern, characterized in that the foaming step is a step of foaming a non-uniformly mixed foaming stock solution. 2. A mixing head device for a foaming machine having a branch nozzle and a discharge nozzle, wherein the branch nozzle is connected to a mixing chamber to branch the passage of the foaming stock solution into two or more, and the discharge nozzle is connected to the mixing chamber and branches the passage of the foaming stock solution into two or more. It is connected to a nozzle and discharges the foaming stock solution and mixes it non-uniformly, and at least one discharge nozzle has a coloring component introduction tube and a mixing device that uniformly mixes the coloring component into the foaming stock solution. A mixing head device for a foaming machine for producing a synthetic resin foam having a multicolor pattern, characterized in that:
