【発明の詳細な説明】
本発明は、流滴性、霧防止性及び耐プレートアウト性に
優れた農業フィルム用塩素含有樹脂組成物に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a chlorine-containing resin composition for agricultural films that has excellent droplet properties, fog prevention properties, and plate-out resistance.
塩化ビニル樹脂に代表される塩素含有樹脂は、保温性、
耐候性、経済性等にすぐれる為、ハウス栽培やトンネル
栽培などの農業用フィルムとして多量に使用されている
。Chlorine-containing resins, such as vinyl chloride resin, have heat retention,
Due to its excellent weather resistance and economic efficiency, it is widely used as an agricultural film for greenhouse cultivation, tunnel cultivation, etc.
の透過が少なくなり、作物の育成に好ましくなく、そこ
で水滴付着を防止する為にある種の流滴剤をフィルム内
に練り込み、流滴フィルムあるいは防滴フィルムとして
市販使用されるに至っている。This reduces the permeation of water, making it unfavorable for crop growth.Therefore, in order to prevent water droplets from adhering to the film, some type of droplet agent is kneaded into the film, and it has come to be used commercially as a droplet film or a drip-proof film.
ところがこのような流滴剤を含む農業用塩素含有樹脂フ
ィルムを使用したハウスやトンネルにおいては、流滴剤
を含まない農業用塩素含有樹脂フィルムを使用したもの
に比して、流滴性に優れ、水滴の何輪現象はきわめて少
なくなるという長所を持つ反面、朝夕などの気温の変化
が激しい時に、n(もやと言うこともある)の発生が著
しいという短所を併せ持つことが明らかになってきた。However, greenhouses and tunnels that use agricultural chlorine-containing resin films that contain such droplet agents have superior droplet flow properties than those that use agricultural chlorine-containing resin films that do not contain droplet agents. It has become clear that while it has the advantage of extremely reducing the number of rings of water droplets, it also has the disadvantage of significantly generating n (sometimes called mist) when the temperature changes rapidly, such as in the morning and evening. Ta.
この霧用縁はハウス栽培やトンネル栽培等にとって最も
大切な冬場に多く発生し、作業性の低下をもたらすこと

発生の抑制−防止の為、種々の方法が提案されてはいる
が、いずれも十分な効果は無く、その有効な方法が熱望
されていた。This mist edge often occurs during the winter, which is the most important time for greenhouse cultivation and tunnel cultivation, and it causes a decline in workability, and although it is not clear whether it is related to the origin of the Song, it can prevent the occurrence of diseases, reduce buds falling, etc. This phenomenon is said to cause fruit drop, and is highly criticized by gardeners. Until now, various methods have been proposed to suppress or prevent the occurrence of fog, but none of them have been sufficiently effective, and an effective method has been eagerly awaited.
また、プレートアウトとは、塩素含有樹脂を成形加工す
る際長時間の加Tにより成形加工機の金属表面、例えば
カレンダーロールのロール表面に配合剤の一部が析出し
付着する現象であり、プレートアウト現象があられれる
ことは成形品の外観、表面性をそこなうばかりでなく、
生産性を著しく落とすという不利益をまねく。In addition, plate-out is a phenomenon in which a part of the compounding agent precipitates and adheres to the metal surface of the molding machine, such as the roll surface of a calender roll, due to long-term heating when chlorine-containing resin is molded. The out phenomenon not only damages the appearance and surface properties of the molded product, but also
This results in the disadvantage of significantly reducing productivity.
