理に加えて粗粉砕物の乾燥処理も同時に行う。Next, the coarsely pulverized product is further pulverized by a ball mill using ceramic balls to obtain fine powder particles.
At this time, the surface temperature of the ceramic ball is increased from 90 ° C to 12 ° C.
The temperature of the room is adjusted to 80 ° C. or lower within the range of 0 ° C., and the drying of the coarsely crushed material is performed simultaneously with the grinding.

Moisture content is efficiently removed from the coarsely pulverized material. Also,
When the coarsely pulverized material is separated from the ceramic balls, it is rapidly cooled. Therefore, the fibers in the coarsely pulverized material undergo expansion and contraction by being repeatedly subjected to heating and cooling, and the leading ends of the fibers are efficiently ground by the ceramic balls. As a result, finely ground cellulose-based fine particles having an independent particle size with little cilia on the peripheral surface are obtained.

Then, the cellulosic fine particles having a uniform particle diameter and a hard white pigment (surface particles) smaller in diameter than the cellulosic fine particles are mixed in a ball mill, and the obtained mixed particles are dispersed in the air. By applying mechanical thermal energy mainly to impact force to the particles, the cellulose-based fine powder is used as the base particles, and the white pigment particles are supported on the outer peripheral surface of the base particles.

好適とされる。Here, the peripheral surface of the cellulose-based fine particles serving as the base particles may be completely covered with the white pigment by sufficiently adding the white pigment, but the amount of the white pigment added is intentionally reduced. Thereby, a desired hue may be obtained without completely covering the cellulose-based fine particles with the pigment. As the white pigment, titanium oxide, lithopone, white carbon, calcium carbonate and the like can be used. In particular, titanium oxide is thermally and chemically stable, and has excellent coloring power and hiding power. Therefore, sufficient whiteness can be imparted to the obtained wood-like molded product, which is preferable. In addition, this white pigment
It is assumed that the particle size is adjusted to be sufficiently smaller than the above-mentioned cellulose-based fine powder particles. Specifically, those having a thickness of about 0.1 μm are preferable.

A plywood 103 is adhesively fixed between the protrusion 16 and the upward frame 102. Thereby, the resin extruded product 1 does not bend significantly even when a load such as a person or a load is applied. Further, since the height of the hollow portion 13 is equal to the thickness of the flooring 101a, the resin extruded product 1 and the flooring 10a
1a is flush. Further, as described above, the resin extruded product 1 has a woody texture and a grain pattern. Therefore, depending on the attachment of the resin extruded product 1, the design of the up frame 102 is not impaired, but may be improved.
