LAMINATED MATERIAL AND ITS MANUFACTURE

摘要

PURPOSE:To supply a laminated material having great strength and high acoustic and heat insulation properties stably at a low cost, by laminating a plurality of lignocellulose stems which have been cut and rolled. CONSTITUTION:A rolled stem 4 whose one side is composed of the skin 1a of the stem 1 is formed by cutting the lignocellulose stem 1 with a knife 2 in the direction of a fiber and rolling the same by a rolling mill 3. Sheetlike members 5 are formed by arranging a plurality of rolling stems 4 in parallel with each other. A laminated material 10 is manufactured by a method wherein a resinous adhesive agent is applied to the sheetlike members 5 and hot press molding is performed by a press machine by piling up the sheetlike members 5 one upon another. Although the various lignocellulose stems are available, a kaoliang stem is preferable. Pressure to be applied to the stem by the rolling mill 3 is selected out of a range of 0.5-10kg/cm<2>. It is preferable that the rolling stem 4 is arranged by sliding a node 1c of the same from the node1c of the next rolling stem 4. A kind or two or more kinds adhesive agents are selected out of an insocyanate series adhesive agent or thermosetting resinous adhesive agent or normal-temperature setting resinous adhesive agent or aqueous emulsion resinous adhesive agent.
