▎ 摘　　要

NOVELTY - Greenhouse UV film comprises ethylene-vinyl acetate (EVA), plasticizer, antioxidant, nano-titanium dioxide and ultraviolet conversion agent including triphenyl antimony, benzene propanoic acid compound, nano-manganese dioxide, phosphate coupling agent and nano-graphene oxide. USE - The film is useful in saline-alkali soil (claimed). ADVANTAGE - The film: comprises ultraviolet conversion agent which can absorb the ultraviolet light in sunlight and convert into visible light that can be accepted by plants and promotes the growth of plants; and has potential market value. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing greenhouse UV film comprises (a) adding EVA, plasticizer, antioxidant, nano titanium dioxide and ultraviolet conversion agent into a high-speed disperser and carrying out dispersion and (b) adding the dispersed material into an extruder, carrying out extruding, blow molding and stretching the product in longitudinal and transverse directions and rolling to obtain the finished product.
