Preparation and Characterization of Polyethylene/Ethylene Vinyl Acetate Composite Non-Dropping Greenhouse Film

Abstract:

For the problem it is easy for the film to generate fog and drop in greenhouse, Polyethylene/Ethylene Vinyl Acetate (PE/EVA) composite greenhouse film was prepared by co-blending and extrusion. The impact of preparation parameters and the dosage of anti-fogging and anti-dropping masterbatch on the mechanical properties and non-dropping properties of the film has been investigated by versatile mechanical testing machine, atomic force microscope (AFM), contact angle tester, water bath acceleration method. The results show that the elongation at break and tensile strength of the composite film, contact angle of water and the film have decreased after added the anti-fogging and anti-dropping masterbatch. The addition of the anti-fogging and anti-dropping masterbatch can increase the non-dropping property of the greenhouse film greatly.
