摘要： PURPOSE:To inexpensively prepare a flexible metal foil clad laminated sheet excellent in thickness accuracy, soldering heat resistance and dimensional stability by a continuous lamination method by continuously applying a release agent to the contact surface with an impregnated base material of an air shielding film on the spot before laminating the air shielding film to the impregnated base material. CONSTITUTION:The long base material unwound from a reel 1 is passed through a dryer 2 if necessary to be dried and continuously impregnated with a radical curable resin solution after drying by a resin impregnating coater 3. The uncured laminate 10 is successively guided to a heating furnace 7 to be usually heated to 70-150 deg.C. As a catalyst, org. peroxide is used. Next, the laminated sheet 11 is continuously taken up by a taking-up machine 8 to be taken up by a product winder 9. When a reel 4 is a film-like air shielding body, the laminated sheet is peeled off from the product by the taking-up machine 8 to be taken up by a winder 12. When a metal foil 5 is laminated to a single surface and an air shielding film 4 is laminated to the other surface, a solution of a silicone release agent is applied to the contact surface with the base material of the air shielding film unwound from the reel 4 by a gravure coater 14 and the coated one is passed through a drying zone 15 to remove a solvent. The air shielding film taken up by the winder 12 is supplied to the reel 4 and the release agent is applied to said film to repeatedly use the film.

摘要： PURPOSE:To suppress the rapid advance of reaction and to improve productivity by a method in which in curing process, hot blast is first applied onto an uncured laminate, and it is switched over to the hot curing by conduction at the stage where the rate of its curing reaction reaches specified value or less, and then at the stage where the rate of the reaction reaches specified range, the laminate is again cured by hot blast curing. CONSTITUTION:The preheating furnaces 10, 15 by hot blast are provided at the sides upstream and downstream of a double belt press 11 adjacently thereto. The laminate covered with metallic foil and/or mold release film 8 passes the preheating furnace 10, and is pressurized and heated with the double belt press 11, and then passes a post-curing furnace 15, whereby it is cured and becomes a product 20. First, hot blast is applied onto the uncured laminate, and then it is switched over to the hot curing by conduction at the stage where the ratio of curing reaction reaches at most 10%, and at the state where its reaction-ratio reaches at least 15% and at most 80%, the laminate is cured by hot blast curing again. Consequently, the rapid advance of the reaction is suppressed, and its productivity is improved. At the stage where its curing reaction-ratio is at most 105, when it is heated quickly, the foaming of the laminate, the peeling between layers and the separation of mold release film etc. may occur.

摘要： PURPOSE:To minimize run-off of a resin from the end of a laminated sheet when lamination molding is performed and to improve thickness accuracy and surface smoothness by using an impregnation resin treated with a rapid curing treatment on one or both side ends or neighborhood thereof as a base material. CONSTITUTION:When a laminated sheet is prepd. by heating and pressing one or a plurality of base materials coated or impregnated with a thermosetting resin, a treatment for accelerating curing of the impregnating resin on molding is provided in advance on one or both side ends or neighborhood thereof of a continuous base material. The position is pref. in a range of 0-15mm or 0.30mm from the end of the base material and the treatment is done on part of the width or in a narrow tablet-shape. These part are usually parts to be cut off when the laminated sheet turns into a final product after the laminated sheet is molded but they are not necessarily cut off. A prepreg obtd. by impregnating the thus treated base material with a usual resin varnish and drying it exhibits less run-off of the resin from the end part of the base material when it is molded by heating and pressing as the end parts or neighborhood thereof in the width direction are cured more rapidly than the central part.
