The invention discloses a novel water mist prevention film and a preparation method thereof. The water mist prevention film comprises an upper film, a middle film and a lower film, the upper film is a hydrophobic film, the lower film is a hydrophilic film, the middle film is a PET film, and the upper film, the middle film and the lower film are extruded together through an extruder. The thickness ratio of the upper film to the lower film is 1: 1, the surface of the upper film is coated with a hydrophobic coating, and the surface of the lower film is coated with a hydrophilic coating. The hydrophilic antifogging method and the hydrophobic antifogging method are adopted at the same time, the surface of the hydrophobic film is coated with the hydrophobic coating, the surface of the hydrophilic film is coated with the hydrophilic coating, the antifogging effect is good, and the antifogging time is long.
Description
technical field [0001] The invention relates to a waterproof fog film, in particular to a novel waterproof fog film and a preparation method thereof. Background technique [0002] Polyester film has the advantages of high transparency and good thickness uniformity, and is widely used in people's daily life. During the use of the film, when the surface temperature falls below the dew point, the moisture in the air will condense into dew droplets and atomize. The existence of fog droplets will cause light scattering and reflection, reduce the light transmittance of the greenhouse film, directly affect the growth of crops, and the fog droplets falling on the plants will also cause the stems and leaves to rot. At present, there are mainly two ways to improve the anti-fog performance of films: one is based on hydrophobic anti-fog methods, and the other is based on hydrophilic anti-fog methods. The hydrophobic anti-fog method is to use water droplets to have a large contact with...
