Home building components, in which extrusion molding articles of resin materials containing wood powder are frequently used, are described below as a related art.
Extrusion molded articles of synthetic resins have been frequently used for highly processed building components like a door sash instead of wooden components manufactured by natural timbers. The materials for these extrusion molded articles of synthetic resins are, for example, a hard vinyl chloride resin with which several tens percentage of wood powder is blended. The extrusion molding article comprising the aforementioned materials can be previously formed into a desired shape while the natural timbers require several times of planing steps. Therefore, processing steps after the molding can be largely reduced in addition to enabling the article to be cut with a saw or to be fixed with nails, which makes the construction so easy.
However, the new article according to the art described above yet involves several problems that its specific gravity is so large compared with that of timbers and its surface becomes so hard by forming skin layers on the surface that wood-like touch is lost. Moreover, since its compatibility with vinyl acetate based adhesives or paints that are commonly used for the wooden components is low, adhesion or painting with the resin was difficult. Therefore, the uses of this new article were limited. For the purpose of solving the aforementioned problems, an extrusion molding with a low degree of foaming has been applied after adding a blowing agent in the resin material to make the specific gravity of the molded article nearly equal to that of the natural timber components.
Notwithstanding the specific gravity of the molded product nearly identical with that of the natural timber components, problems as described below has still remained for applying an embossing finish.
In the embossing finish, a cylindrical roller provided with a lot of convexities on its surface is pressed on the surface of the molded article to form many tiny grooves on it, thereby printing grain patterns on the surface of the molded article followed by painting on it.
However, since the painting is applied only by a spray-coating, the paint layer so hardly penetrates into the grooved portions formed by the embossing finish that woodlike touch is lost due to light and shade stripes on its surface .
Disclosure of Invention
Accordingly, the object of the present invention is to solve the problems described hitherto that arise after applying an embossing finish to the extrusion molding article that is expected to have wood-like touch. Paints are allowed to penetrate into the patterns formed by the embossing finish for emphasizing its color tone, thereby making the grain patterns clear and enhancing wood-like touch.
The present invention comprises the steps of extrusion molding a molded article having a cross section with a desired shape, applying an embossing finish after removing skin layers formed on the surface, spray-coating a paint on the surface, allowing to penetrate the paint layer into patterns formed by the embossing finish by rubbing with an elastic block and finally removing the light and shade stripes formed by rubbing with a brush.

Brief Description of Drawings
Fig. 1 is an illustrative drawing representing a production process according to the present invention, and Fig. 2 is a perspective view showing an example of the molded article.
Best Mode for Carrying Out the Invention
The present invention will now be described by way of embodied illustrations. However, the invention is not limited thereto.
In Fig. 1, 1 is an extrusion molding machine for synthetic resins, 2 is a cooler and 3 is an extrusion guide. These parts are commonly found in the conventional extruder. A molding die 4 is attached to the extrusion molding machine 1 for continuously molding a molding article having a cross section with a desired shape.
A molded article A having a cross section as shown in Fig. 2 is formed, for example, by supplying a molding material of a synthetic resin to the extruder 1, with which several tens percentage of wood powder, several percentage of blowing agent, stabilizer and reinforcing material, respectively, are blended. A sanding machine 5 is provided in front of the extrusion molding machine to remove skin layers formed on the surface of the molded article A and for applying a satin finish on the surface, thereby exposing countless small pores produced by wood powder and blowing agents for emphasizing wood-like touch of the molded article A as well as for enhancing a compatibility with paints. An embossing machine 6 is also provided in front of the sanding machine 5 to apply an embossing finish on the surface of the molded article arrived at this position. The embossing machine 6 is provided with a press roller on the surface of which a lot of convexities are protruded forming a grain pattern. A grain pattern having thin grooves is printed by pressing this press roller on and penetrating the convexities into the surface of the molded article A.
A spray coating machine 7, rubbing machine 8 and brush 9 are further provided, respectively, in front of the embossing machine 6 for spray coating a prescribed amount of paint on the surface of the molded article A previously subjected to an embossing finish, followed by rubbing the coated surface with a gentle touch of the surface with an elastic block like an urethan foam, thereby penetrating the paint layer into the thin grooves formed by the embossing finish. Then, light and shade stripes appeared on the painted surface of the molded article A are retouched by using the brush 9 to form an uniform painted surface. The molded article is finally finished by drying the coated layer by a conventional method followed by painting a clear lacquer.
According to the aforementioned process, a pattern by the embossing finish clearly appears since the coated paint can penetrate into the thin grooves where it is difficult by the spray coating. Light and shade stripes appeared on the surface of the processed material are erased by rubbing to form an uniformly painted surface, thereby making it possible to obtain a product having a beautiful appearance with highly wood-like touch.
The block used for rubbing the painted surface absorbs few paints since it has an appropriate degree of elasticity. Therefore, an effective painting is made possible since few amount of the paint coated on the whole painting surface comprising the groove part and the other parts is lost while enabling to penetrate the paint into every thin grooves.
The painted surface on which light and shade stripes appear arising from the painted surface other than the thin grooves can be effectively turned into an uniform surface by brushing after rubbing with an elastic block. Thus, it is possible to make the embossing pattern clear by emphasizing the color tone on the thin grooves, further enhancing woodlike touch as a background on the substrate even when both the thin groove portion and the other portions on the surface are simultaneously coated with a paint.
Industrial Applicability
As disclosed herein, the present invention provides an art for solving the problems that wood-like touch is lost due to light and shade stripes when an embossing finish is applied on the extrusion molding article expected to have wood-like touch.
