Abstract
PURPOSE: To manufacture laminated plates mentioned, above of good quality and with good efficiency, by impregnating a plurality of sheet-like substrates with thermosetting resin liquid of unsaturated polyester system, laminating continuously them, curing them in a first furnace and after-hardening them in a second furnace.
CONSTITUTION: Thermosetting resin liquid at a room temperature consisting of a main constituent of unsaturated polyester resin and bridging vinyl monomer and hardening catalyst, and if necessary hardening assistant agent and filler is dried and supplied from a resin supplier 3 to impregnate a plurality of sheet-like substrate 1 (for example, craft paper and unwoven cloth and the like) being transferred continuously. The impregnated substrates 1 are covered with a cover film 4 such as Mylar film etc. and laminated, and the laminate is hardened through a first furnace (consisting of two sections 5, 6) of 60W140°C. Then, the cover film 4 is peeled and the laminate is cut, after-hardening the cut laminate in a second furnace of 140W 190°C.
