This method of manufacturing a wall material is characterized by injecting and foaming resin 4, and its purpose is to uniformly mix the filler over the entire surface of the skin material, and to make the filling material evenly mixed in from the urethane stock solution injection head. To provide a method for manufacturing a wall material in which urethane resin stock solution can be smoothly injected.

In advance, one of the two-component materials of foamable urethane resin, for example, resin (polyol), is infiltrated,
This contaminant is injected into the mixing chamber, and the other liquid, isocyanate [for example, polymethylene diisocyanate (hereinafter abbreviated as MDI)] is supplied to this mixing chasoba and mixed with the above-mentioned gin, and this is injected into the outer skin material. It was then molded.

本発明はかかる従来の欠点を解消せんとするもので、以
下添付図に基づいて詳細に説明する。Therefore, in the past, the filler was mixed in the foamable urethane resin in advance, which caused the filler to precipitate in the resin tank, resulting in an uneven mixing ratio of the filler, and the urethane resin was injected from the injection head. The filler inside is uneven, and when it is injected into the outer skin material, the filler is not evenly distributed over the entire surface of the outer skin material, and when the filler is mixed in, the viscosity of the urethane resin increases and the flow becomes poor. Therefore, there is a drawback that it is difficult to inject urethane resin from the injection head.
The present invention aims to eliminate such conventional drawbacks, and will be described in detail below with reference to the accompanying drawings.

づいて具体的に説明する。The skin material 1 is formed by extrusion molding of a hard thermoplastic resin such as polyvinyl chloride or aluminum into a thin, flat cross-section, and is coated with a primer 2 using a primer coater 5 as shown in FIG. The skin material 1 coated with the primer 2 is transferred directly below the supply nozzle 6, and the powdered filler 3 is dispersed and supplied from the supply nozzle 6 onto the primer 2 of the skin material 1. Here, as the filler 3, an inorganic or organic material such as pearlite or shirasu pearl is used. Next, the resin (polyol) and isocyanate are transferred from the respective tanks 7 and 8 to the mixing chamber 9, and both liquids are mixed to prepare a stock solution of the foamable urethane resin 4. After that, the transferred outer skin material 1 is filled. It is injected onto the material 3 through the nozzle 11. Here, the ratio of the filler 3 to the urethane resin 4 is not intended to be limited, but it is preferable that the ratio of the filler 3 to the urethane resin 4 is about 10%. After the urethane resin 4 has been injected, the skin material 1 is transferred to the pressure molding machine io, and the resin is foamed while being continuously pressed by the pressure molding machine 101 to complete curing. In the present invention, as described above, when mixing foamable urethane resin and powdered filler into the outer skin material and injecting the mixture into the outer skin material to foam, a certain amount of the filler is first sprinkled on the outer skin material. Since the filler is supplied and then the urethane resin is injected, the filler is uniformly spread over the entire surface of the outer skin material before the urethane resin is injected. The filler is evenly dispersed over the entire surface of the outer skin material compared to the case where the filler is mixed in, making it possible to mold urethane foam with uniform quality over the entire surface.Also, since only urethane resin is injected, conventional fillers can be mixed in. The urethane resin does not increase in viscosity in the mixing chamber unlike the urethane resin, and the urethane resin can be smoothly supplied from the injection head or nozzle, improving the efficiency of injection. Moreover, since the filler is sprayed and adhered onto the pre-applied primer, it is not affected by the flow pressure or foaming pressure when injecting the urethane resin, or by the wind pressure when injecting the urethane resin by spraying. Furthermore, the filler is held in a fixed position even when subjected to vibrations after being sprayed, which has the advantage of making it possible to uniformly mix the filler throughout. The present invention will be specifically described below based on examples.
