PURPOSE: A manufacturing method of ethylene vinyl acetate copolymer sheet is provided to prevent a surface of a sheet by a polymerizable UV absorber by curing and to provide an ethylenevinylacetate sheet with improved yellowing stability and UV stabilizing effect without difficulty of process such as melting, dispersion, etc. CONSTITUTION: A manufacturing method of ethylene vinyl acetate copolymer sheet comprises: a step of molding a sheet by mixing a polymerizable UV absorber, a crosslinking aid, a UV stabilizer, and silane coupling agent into an ethylene vinyl acetate copolymer resin. On the basis of 100.0 parts by weight of the ethylene vinyl acetate copolymer resin, the used amount of the polymerizable UV absorber is 0.01-0.5 parts by weight. The vinylacetate content of the ethylene vinyl acetate copolymer is 25-32 weight%. The melt index(190°C, 2.16kg) is 6-30 g/10minutes. |
