Polyethylene resin composition for greenhouse film and preparation method thereof

The invention provides a linear low-density polyethylene resin composition for a greenhouse film and a preparation method thereof. The composition comprises, on the basis of 100 wt% of LLDPE, 100% of LLDPE, 0.05 to 0.3% of a complex cross-linking agent and 5 to 20% of a ULDPE graft, wherein the ULDP...

Beschreibung
Zusammenfassung:	The invention provides a linear low-density polyethylene resin composition for a greenhouse film and a preparation method thereof. The composition comprises, on the basis of 100 wt% of LLDPE, 100% of LLDPE, 0.05 to 0.3% of a complex cross-linking agent and 5 to 20% of a ULDPE graft, wherein the ULDPE graft is a graft copolymer prepared by grafting a styrene (St) monomer to a ULDPE main chain under action of an initiator. A broad-width greenhouse film (with a thickness of no less than 80 mu m and a width of no less than 8 m) produced with the composition as a raw material has high tearing strength and excellent weatherability, can withstand 7-grade to 8-grade sandstorms, has no natural damage even when a greenhouse shed has been constructed from the greenhouse film for more than 900 days and is especially applicable to laying in western regions with frequent sandstorms and long sunshine duration.
