POLYOLEFINIC RESIN FALSE WOOD AND PRODUCTION THEREOF

PURPOSE: To obtain false wood having no plasticlike gloss and similar to a natural tree in appearance by forming a barklike surface layer similar to the surface skin of bark by allowing a solid additive substance to protrude from a surface of a resin patternwise. CONSTITUTION: A barklike surface lay...

Zusammenfassung:	PURPOSE: To obtain false wood having no plasticlike gloss and similar to a natural tree in appearance by forming a barklike surface layer similar to the surface skin of bark by allowing a solid additive substance to protrude from a surface of a resin patternwise. CONSTITUTION: A barklike surface layer similar to the surface skin of bark is composed of a molding material obtained by compounding a substance (solid additive substance) solid at least at 200 deg.C with a polyolefinic resin and formed by allowing the solid additive substance to protrude from the surface of the resin patternwise. As the solid substance, for example, an inorg. filler such as calcium carbonate, alumina kaolin, a thermosetting resin such as a urea resin, bakelite or an epoxy resin and a wood or wooden fibrous substance such as a wood powder, pulp, paper or cotton are used. The wooden fibrous substance is especially pref. because it protrudes from a polyolefinic resin layer patternwise in a fluffed state to form a surface layer similar to the surface skin of bark. The size of the wooden fibrous substance is set to 1-500μm and, in the case of below 1μm, the surface of false wood is smooth and a natural feeling is hardly developed.
