この発明は、いわゆるＳＭＣ，すなわち、フィラー混入
樹脂材料をシート状に成形してなる成形材料の製法に関
する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method for producing a molding material formed by molding a so-called SMC, that is, a filler-containing resin material into a sheet shape.
近時、成形工程の合理化等の目的で、成形材料として粉
末品にかえて、あるいは粉末品とは別にＳＭＣが用いら
れるようになってきた。Recently, SMC has come to be used as a molding material instead of or in addition to powder products for the purpose of streamlining the molding process.

のであった。Conventionally, this method uses a uniformly colored material in which colorants such as pigments are dispersed in the resin and filler, or colored particles such as mica grains, colored aluminum foil pieces, and colored vinylon staple fibers are dispersed in the resin and filler. Because it is made by using a material with a uniform pattern, it lacks variation in pattern and cannot produce the richly varied patterns seen in natural marble. For this reason, conventional SMC has been completely unsatisfactory in terms of producing products with beautiful appearance.
上記事情に鑑み、この発明は、外観の美麗な製品を得さ
せるシート状成形材料の製法を提供することを目的とす
る。In view of the above circumstances, an object of the present invention is to provide a method for producing a sheet-shaped molding material that allows a product with a beautiful appearance to be obtained.

とする。In order to achieve the above object, the present invention provides a method for manufacturing a sheet-like molding material that includes a step of covering a filler-containing resin material with a film and then forming it into a sheet, in which a coloring agent is applied to the film and a filler-containing resin material is coated with a filler. The gist of this invention is a method for producing a sheet-like molding material, which is characterized by covering a mixed resin material.
以下に、この発明を、その実施例をあられす図面を参照

A reinforcing material 4 such as glass cloth or glass fiber is continuously arranged. Then, the upper cover film 1a is continuously superimposed thereon. The sheet-like body 5 thus obtained is placed between a pair of upper and lower forming rolls 6a, 6b, and is continuously formed into a sheet-like shape having a desired thickness. Then, once rolled up, or without being rolled up, it is aged and made into a sheet-like molding material.

れる。This process itself is no different from the conventional one, but in this invention, before placing the filler-containing resin material 3 on the lower cover film lb, a colorant 7 such as a pigment paste or a dye solution is placed on the cover film lb. Apply it in a desired pattern such as stripes or spots. This point is different from the conventional method. The colorant may be in powder form. The pattern can be chosen freely.

The resulting sheet-like molding material has a pattern rich in variation, such as that of natural marble. By changing the concentration of colorants such as pigments and dyes, it is possible to create shading in the pattern. Upper and lower cover films la,
By applying a coloring agent to the lb, a pattern can be created on both the front and back sides of the sheet-like molding material.

対の成形ロール６ａ。FIG. 2 represents another embodiment. As shown in the figure,
Cover films la and lb such as polyester films are continuously unwound from winding rolls 2 and 2. A coloring agent 7 is first applied onto the lower cover film 1b, and then a resin material 3 mixed with a filler such as an inorganic powder is continuously arranged in a layered manner. In this case, the filler-containing resin material 3 is once sent to a roll device 8 such as a coater, and at this time, it is mixed with a reinforcing material 9 such as short glass fiber, and is arranged in a layered form on the cover film lb. . and,
The upper cover film la is continuously superimposed thereon. Thereafter, the obtained sheet-like body 5 is formed into a pair of upper and lower forming rolls 6a.

実施例と同様である。6b and is continuously formed into a sheet of a desired thickness, and once rolled up, or without being wound up, it is aged and made into a sheet shaped molding material, which is different from the previous example. The same is true.

せるものである。As seen above, the method for producing a sheet-shaped molding material according to the present invention includes the step of covering a filler-containing resin material with a film and then forming it into a sheet, in which a colorant is added to the film. Since the filler-containing resin material is coated with the resin material, it is possible to easily obtain a sheet-like molding material having a pattern rich in variation.
