の均一混合が難しく外観や物性を悪化させる。[Detailed Description of the Invention] The polypropylene waste referred to in the present invention is any waste made of polypropylene, such as yarn waste generated during fiber production, residual yarn and ear waste generated during woven or knitted fabric production, and waste generated during plastic molding. This means that there is no problem even if other fibers or plastics are mixed in them. In the present invention, the polypropylene waste is heated to form granules, in which case the polypropylene contains 30% by weight or more, preferably 40 to 60% by weight, based on the total weight of the granules. When the content of polypropylene is less than 30% by weight, it is difficult to obtain a light-weight molded product having an apparent density of 0.95 g / cm3 or less according to the present invention, and it is difficult to uniformly mix wood chips, other fibers, and other plastics, thereby deteriorating appearance and physical properties. .

If the amount of wood chips is less than 5% by weight, the impact strength is reduced and a woody appearance cannot be obtained. In addition, the absorption and release of water, which is a characteristic of wood, is insufficient, and there is a problem that dew is easily formed on building materials and wall materials. If the amount of wood chips exceeds 40% by weight, mixing with the polypropylene becomes difficult and the appearance is impaired, and the density becomes 0.96 g / cm3 or more, and the material rots and the physical properties are easily lowered.

うので好ましくない。In the present invention, these wastes are heated and mixed into granules, and then kneaded with a melt extruder. If the mixture is directly melt-extruded without being granulated, the appearance and physical properties are deteriorated due to uneven mixing, which is not preferable. In granulation, the propylene or the low melting point material semi-melts or melts to serve as a binder, and holds wood chips and a high melting point material to form granules of about 1 to 20 mm. In this case, water is contained in an amount of 2 to 40% by weight, preferably 5 to 30% by weight. However, foaming occurs during the subsequent melt extrusion, thereby reducing the weight and improving the impact resistance (possible nailing).
Therefore, it is easy to obtain excellent molded products. If the water content is more than 40% by weight, the foaming is so severe that the physical properties such as a decrease in strength are impaired, which is not preferable.

Temperatures above ℃ are required. There is no problem if the temperature is 260 ° C. or higher at which the polyester or the like melts. However, 300 ° C. or higher is not desirable because other fibers and plastics are colored and decomposed to deteriorate physical properties. There is no problem with any molding method such as extrusion molding, injection molding, cast molding, lamination molding, and compression molding.
