関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an agricultural polyvinyl chloride film (hereinafter abbreviated as agricultural vinyl chloride film). More specifically, it relates to an agricultural PVC film that does not cause discoloration even when in long-term contact with metal parts that are aggregates in facility houses, has excellent weather resistance, and does not cause deterioration in film quality or processability. .

まで上昇する。Agricultural PVC film is overwhelmingly used as a covering material for facility houses, but its drawback is that it causes discoloration in the areas where it comes into contact with house aggregates. The greenhouse is heated by sunlight, and the temperature of the aggregate becomes particularly high, reaching nearly 80°C in midsummer at the part where it comes into contact with the film.

大な問題となっている。Metal or plastic pipes, wood, metal frames, etc. are mainly used as house aggregates, but PVC film turns brown when it comes into contact with the aggregate, and the browned parts become brittle and break easily. Become. In recent years, houses have become larger, and springs are used on metal rails,
The so-called rim method for fixing the film is increasing.
The phenomenon of discoloration of PVC films at metal contact points is becoming an increasingly serious problem.

きない。Agricultural PVC film is usually made by blending plasticizers, metal soaps, stabilizers, droplet agents, and ultraviolet absorbers with vinyl chloride resin, but among them, metal soap stabilizers are used to improve heat resistance. plays an important role. However, there are limits to these additions; for example, if a large amount of metal soap is added, it may cause poor gelation, decrease in transparency, or poor thermal stability (if large amounts of zinc-based metal soap are used, zinc burning may occur). (on the contrary, the thermal stability decreases), etc., and when a large amount of stabilizer is added, it causes bleeding, stickiness, decrease in transparency, etc. In addition, as heat-resistant and weather-resistant stabilizers, there are additions of epoxy plasticizers such as epoxidized soybean oil and epoxidized linseed oil, and so-called epoxy resins that are condensates of bisphenol A and epichlorohydrin, but these additions have some effects. However, if a large amount is added, problems such as plate-out, buildup, stickiness, and staining after spreading occur, and the amount added is practically limited to an upper limit. Increasing the amount of ultraviolet absorber may have some effect, but certain wavelengths will be completely cut off, which may affect some crops, so it cannot be used in large quantities.
