PURPOSE:To make the woodlike board material into a condition wherein the surface has few thin fibrous matter, the surface of a board material free from nap and having a soft feel, by a method wherein a color pellet which is obtained by mixing up cellulose fine powder and granule, a colored pigment and vinyl chloride resin, which has a specified polymerization degree, with each other and solidifying them is extrusion-molded into a boardlike state. CONSTITUTION:A woodlike board material 20 is obtained by performing extrusion molding from a color pellet into a boardlike state. The color pellet raw material is grinding-treated and obtained by mixing up a cellulose fine powder and granule 11 on the surface of which a white inorganic pigment 10 is carried, a colored pigment and vinyl chloride resin having a polymerization degree to the extent of 1000 with each other and solidifying them. A matter obtained by grinding-treatment of a coarse pulverized matter of raw materials of various vegetable cell bodies such as the coarse pulverised matters of wood, bagasse and rice straw is used as the cellulose fine powder and granule 11 carrying the white inorganic pigment 10. |
