The present invention relates to a manufacturing apparatus of a weatherproof sheet. According to the present invention, the manufacturing apparatus of a weatherproof sheet comprises: an extrusion die for extruding by pressurization as formed with an extrusion path in a certain form; a main resin supply unit connected with a center part on an inlet side of the extrusion path of the extrusion die to supply a main resin raw material; a UV additive supply unit connected to the inlet side of the extrusion path of the extrusion die to be slantly arranged with respect to the main resin supply unit, and supplying a UV additive; and a cooling device cooling a molded product extruded by the extrusion die. Accordingly, provided are effects of improving mechanical properties by having a UV blocking layer coated on a surface of the sheet while the sheet is extruded, by supplying the UV additive in an extruding manner to mold a main resin by supplying the main resin to a molding device and extruding the same, and to form a UV blocking layer on inner and outer surfaces of the sheet at the same time, and of enhancing price competitiveness since manufacturing costs can be significantly reduced. |
