題があった。Previous technology and its problems In general, a mixture of wood flour and polypropylene resin is known as a wood-based composite fat phase that is a mixture of wood flour and resin. These wood-based composite resin materials have properties similar to those of wood in terms of thermal properties, sound insulation, heat insulation, breathability, moisture absorption, etc., but the wood grain that appears on the surface The patterns such as cedar and cedar are different from wood, and in order to make the appearance such as wood grain pattern and color similar to that of wood, the above-mentioned direct composite resin material is used. 1. A method for surface treatment of a resin material such as the above-mentioned pattern by forming irregularities on the surface of the resin material and treating the surface of the water thread composite resin material by a method such as painting or printing. In the case of the above-mentioned wood-based composite resin material with an uneven surface, if shading is not produced due to the adjustment of light rays, the surface does not appear close to the appearance of wood, and it is difficult to paint or When printing, a film of paint or the like is formed on the surface, which impairs the breathability and moisture absorption properties of the wood-based composite resin material. The problem was that he was unable to perform.

である。The heat medium oil is heated to, for example, 250 to 300° C. so that the protrusions 3 of the a-Ra can sink into the resin plate and burn the wood powder. still,
Reference numeral 4 in the figure is a supply/discharge pipe for supplying and discharging heat medium oil to and from the roller Ra.
従って、この装置によれば、以下のようにして樹脂板に
に木目が焼き付けられる。Therefore, according to this device, the wood grain is burned onto the resin board in the following manner.

複合樹脂がダイス2を通して押し出され、木質系複合樹
脂材としての樹脂板Nが形成される。この場合、木粉に
2種以上の着色をしておけば、例えば、濃淡によるぼか
し等の種々の模様が樹脂板にに形成される。First, a wood-based composite resin made by mixing wood flour and resin is extruded through a die 2 by extrusion Jal, and a resin plate N as a wood-based composite resin material is formed. In this case, if the wood powder is colored with two or more types, various patterns, such as shading with light and shade, can be formed on the resin board.
また樹脂として着色性の優れたポリエチレン樹脂を用い

目模様として形成される。Next, the L resin plate is continuously sent out from the extruder l to the L burner 4=one roller Ra, Rb. In this case, the rollers Ra and Rh are rotated by a drive device not shown, and roll by sandwiching the resin plate. At this time, since the width between the rollers Ra and Rb is narrower than that of the resin plate N, as shown in FIG. Four wood grain-like parts 5 are continuously formed on the board. Further, since the roller Ra is heated by the heat medium oil, the protrusion 3 melts the resin in the recess 5 and burns the wood powder, which causes the wood powder to burn and become carbonized. , the four portions 5 are formed as a wood grain pattern that has changed to a substantially black color.

Further, in the above embodiment, the rollers are provided in pairs, and one roller Ra
Although the protrusions 3 are only embossed, the present invention is not necessarily limited to this and other arrangements may be made. Furthermore, if the wood-based composite resin material is a round bar or a board with a bent cross section, it may be modified as appropriate, such as by providing a plurality of rollers. Furthermore, in the above embodiments, the protrusions with a wood grain pattern are formed on the roller, but the invention is not necessarily limited to this, and various patterns may be formed. Also, roller R
The heating means for heating a is not limited to the one using the above-mentioned heating medium oil, but may be, for example, an electric heater or the like, and the design may be changed as appropriate.

膚に近いものにすることが可能である。As explained above, according to the surface treatment method for a wood-based composite resin material according to the present invention, a pattern is baked onto the surface of the wood-based composite resin material, which improves the air permeability and moisture absorption of the wood-based composite resin material. A wide variety of patterns can be applied to the surface of the wood-based composite resin material without impairing properties such as properties. In particular, when a wood grain pattern appears, in addition to the shading of the four parts where the pattern is baked, the color of the burnt wood powder in the recesses
It is extremely effective because not only the properties but also the appearance quality become closer to that of wood. In addition, poly 11! is used as a resin! When vinyl chloride resin is used, it is possible to make not only the pattern but also the color tone similar to that of wood.
