脂フィルムに関する。[Detailed description of the invention] [Object of the invention] (Industrial application field) The present invention relates to agricultural synthetic resin films, and more specifically,
The present invention relates to an agricultural synthetic resin film that suppresses fog generated near the inner surface of a so-called agricultural greenhouse film, which is made by blending a polyhydric alcohol compound containing a polyfluoroalkyl group with a synthetic resin.

めのハウス栽培用のフィルムとして使用されている。(Prior art) Vinyl chloride resins and polyolefin resins are relatively inexpensive and have excellent transparency, weather resistance, mechanical strength, etc., so they can be used for stimulated, semi-forced or suppressed cultivation of agricultural crops such as vegetables and fruit trees. It is used as a film for greenhouse cultivation.

テル等）がフィルム残材に配合されている。The films used in these agricultural greenhouses tend to become cloudy when fog generated inside the greenhouse condenses on the inner surface of the film, that is, water droplets adhere to the inner surface of the film. This results in a decrease in sunlight transmittance, which adversely affects the growth of agricultural crops. In order to prevent this condensation, a surfactant (for example, sorbitan fatty acid ester, glycerin fatty acid ester, etc.), which is generally called an antifogging agent, is blended into the film residue.

ている。However, in agricultural greenhouses covered with synthetic resin films containing such protective agents, although it is effective in preventing condensation, in the mornings and evenings from autumn to winter, when the temperature difference between the inside and outside of the film becomes large, A lot of fog occurs in Japan, and fog prevention measures have become a problem.

濡らすことによる各種病害発生の原因となり１重大な問
題となっている。The phenomenon of generation of fog not only reduces the transmittance of sunlight and deteriorates the working environment for agricultural work, but also causes the occurrence of various diseases due to wetting the crops grown in greenhouses, which is a serious problem.

提案されているが、十分なものとはいえない。In order to prevent such fog generation, a method of kneading a small amount of fluorine-based surfactant into a synthetic resin film has been proposed, for example in Japanese Patent Publication No. 59-35573 and Japanese Patent Application Laid-open No. 57-192445. It cannot be called a thing.

添加剤が求められている。(Problems to be Solved by the Invention) Although fluorine-based surfactants have a certain degree of fog prevention effect, they cannot completely prevent fog. In order to completely prevent fog, it is necessary to increase the amount of fluorosurfactant added, but increasing the amount of fluorosurfactant not only increases costs, but also improves the weather resistance and heat coloring properties of the film, etc. This has an adverse effect on performance, resulting in poor performance. Therefore, there is a need for an additive that can completely prevent fog generation by adding a smaller amount.

According to the findings of the present inventors. It has surprisingly been found that the fog-proofing effect of agricultural synthetic resin films is significantly improved by the compounds of the present invention which are insoluble or soluble in water.The conventionally used fluorine-based nonionic surfactants It is highly soluble in water, and in this respect it is clearly distinguished from the compounds of the present invention.

価アルコール化合物で極めて有効に阻止されるというこ
とは驚くべきことである。In greenhouses using agricultural films, especially agricultural films containing protective agents to prevent condensation, the use of antifogging agents slows down the adsorption speed of supersaturated water vapor near the inner surface of the film. Therefore, it is thought that fog is generated because minute water droplets that are not adsorbed float near the inner surface of the film, but this is because the water-insoluble or poorly soluble fluorinated polyhydric alcohol compound of the present invention is different from conventional water-soluble compounds. It is surprising that this is so effectively prevented.
