Polyethylene agricultural film resin composition and its preparation method
The invention provides a polyethylene agricultural film resin composition and its preparation method. The composition comprises 100wt% of LLDPE (linear low-density polyethylene), 0.05-0.3wt% of a complex formulation crosslinking assistant and 10-35wt% of an EVA (ethylene-vinyl acetate) grafter, wher...

| description | The invention provides a polyethylene agricultural film resin composition and its preparation method. The composition comprises 100wt% of LLDPE (linear low-density polyethylene), 0.05-0.3wt% of a complex formulation crosslinking assistant and 10-35wt% of an EVA (ethylene-vinyl acetate) grafter, wherein the EVA grafter is a graft copolymer obtained through grafting a styrene monomer to the main chain of EVA under the action of an initiator. Broad-width shed films produced through treating the composition as a raw material have a high tear strength and an excellent weatherability, can defend 7-8 grade dust storms, and cannot be naturally damaged after the continuous shed buckling for above 700 days. |
