Abstract

PURPOSE:To obtain a fluororesin film which has excellent antifog and antimist properties without detriment to its transparency by coating one side of a fluororesin film with a specific fluorocooligomer. CONSTITUTION:One side of a fluororesin film (e.g. a film made from a tetra- or trifluoroethylene resin) is coated with a fluorocooligomer obtd. from 100 pts.wt. unsatd. ester having a 4-20C polyfluoroalkyl group and 1-70 pts.wt. other copolymerizable compd. (e.g. ethylene, vinyl acetate, vinyl chloride, or styrene). A pref. example of the polyfluoroalkylated unsatd. ester is an acrylic or methacrylic ester having a terminal perfluoroalkyl group. A pref. film is one made from a tetrafluoroethylene resin.

However, when the temperature difference between the inside and outside of the vinyl house is large, water drops adhere to the inside of the vinyl house to cause fogging of the film, and fog is generated near the film surface inside the vinyl house and stays there. Not only is the light transmittance lowered, but there is also the problem of causing diseases in crops.

In recent years, the weather resistance is high,
The characteristics such as excellent light transmittance have been evaluated, and the demand for fluororesin agricultural and horticultural films is increasing. Agro-horticultural film made of fluororesin has a high molding temperature when the fluororesin is formed into a film. Therefore, if a conventional surfactant is blended to form a film, the surfactant is decomposed. . Further, when the above-mentioned fluorine-containing oligomer is blended to form a film, there is a problem that the fluororesin becomes cloudy.

EFFECTS OF THE INVENTION According to the present invention, it is possible to obtain a fluororesin agricultural and horticultural film having excellent antifogging properties and antifog properties. Further, according to the present invention, since the property can be imparted only by coating a small amount of the fluorine-containing copolymer oligomer, it is simple and there is no fear of impairing the transparency of the fluororesin film. Further, since the fluorine-containing copolymer oligomer is also excellent in adhesion to the fluororesin film, the fluororesin agricultural and horticultural film of the present invention continues to have antifogging and fogproofing effects even during long-term field use. It is also excellent in terms.
