| 摘要 |
The present invention relates to an agricultural film with improved heat-retaining and thermal insulation properties, wherein an ethylene-vinyl acetate (EVA) resin, as a first component, is mixed with a surface-modified hydrophilic aerogel or a silylated aerogel, as a second component, having a porosity of 80-99.8%, a particle size of 10-100 nm and a refractive index of 1.007-1.05, and a polymer (EVA-g-MAH), as a third component, in which maleic anhydride is grafted to an EVA resin, and one or more components, as a fourth component, selected from a polyethylene wax and a silicone-modified polyethylene wax are contained or not contained. |
