PURPOSE: A variegated pool-cover tarpaulin prepared from a PVC compound and a manufacturing method thereof are provided to enhance visuality of a PVC based variegated tarpaulin product, to impart an aesthetically appealing appearance to a pool cover, and to enable variegated patterns to be maintained for a prolonged period of time even after use outdoors. CONSTITUTION: The manufacturing method of the variegated pool-cover tarpaulin comprises: mixing materials including 100 wt% of a PVC resin, 40 to 65 wt% of phthalate plasticizer, 10 to 40 wt% of an inorganic compound, 2 to 4 wt% of a barium-zinc compound based stabilizing liquid, and 0.5 to 0.8 wt% of ultraviolet stabilizer(S2); adding a cyan blue master batch pigment and a titanium white pigment to the resultant mixture and mixing the same using a Banbury mixer to form blue and white PVC films(S4); producing variegated PVC films using a calender device(S6); processing a triple-layered tarpaulin product by sequentially laminating a PVC film as an upper layer, fabric coated with paste resin as a middle layer, and a PVC film as a lower layer(S8) and a PVC film for a lower layer(S8,S10); coating a surface of the tarpaulin product with a liquefied acrylic resin(S12); and finishing the coated tarpaulin product(S14).
