MANUFACTURING METHOD OF LIGNEOUS PRODUCT AND LIGNEOUS PRODUCT

To make texture of a ligneous product approach natural wood more than ever.SOLUTION: In the manufacturing method of a ligneous product 200 for extruding the measured molten B1, M1 to M3, which have been melted from the first base material B1 and the master batches M1 to M3, from the opening of the mold 141, the first base material B1 made of a mixture of high density polyethylene and the first pigment is used as the first base material B1, as a master batch, the mixture of polystyrene or acrylonitrile styrene with the second pigment is used, and in a state in which a part relatively high in the concentration of the first base material B1 in the melt B1, M1 to M3, and a part relatively high in the concentration of the master batches M1 to M3 remain in the melt B1, M1 to M3, the melt B1, M1 to M3 are extruded.SELECTED DRAWING: Figure 9 【課題】木質様製品の質感を、従来よりも天然木に近づける。【解決手段】計り取った第一ベース材Ｂ1とマスターバッチＭ1〜Ｍ3とを溶融させた溶融物Ｂ1，Ｍ1〜Ｍ3を金型１４１の開口から押し出す木質様製品２００の製造方法において、第一ベース材Ｂ1として、高密度ポリエチレンと、第一顔料と、を混合したものを用い、マスターバッチとして、ポリスチレン又はアクリロニトリルスチレンに第二顔料を混合させたものを用い、溶融物Ｂ1，Ｍ1〜Ｍ3の中に第一ベース材Ｂ1の濃度が相対的に高い部分とマスターバッチＭ1〜Ｍ3の濃度が相対的に高い部分とが残っている状態で、溶融物Ｂ1，Ｍ1〜Ｍ3を押し出す。【選択図】図９
