【０００１】
【発明の属する技術分野】
本発明は、農業用塩化ビニル系樹脂フィルムに関するものである。
【０００２】
【従来の技術】
従来より、ハウスやトンネル等の農業用施設の被覆材（以下「農業用被覆材」という）として、塩化ビニル系樹脂フィルム、ポリエチレンフィルム、エチレン−酢酸ビニル共重合樹脂フィルム、ポリエステルフィルム、或いはこれらの積層フィルム等が使用されている。中でも、塩化ビニル系樹脂フィルムは、光線透過率、保温性、機械的強度、耐久性、フィルム化するときの作業性、経済性等の諸特性のバランスが良いことが評価され、上記の農業用被覆材として広く使用されている。
【０００３】
【発明が解決しようとする課題】
ところで近年では、農家の人手不足、省資源等の理由により、長期間に亘って展張しておくことが可能な農業用被覆材が求められている。
そのため、上記の農業用塩化ビニル系樹脂フィルムにおいても、耐候性を向上させ、長期間に亘って展張しておくことが可能となるように、光安定剤として化２に示す構造単位を有するものを添加することが提案されている。
【０００４】
【化２】
上記のヒンダードアミン系化合物は、農業用塩化ビニル系樹脂フィルムの耐候性を向上させるという効果を発揮し、それを添加しない農業用塩化ビニル系樹脂フィルムに比較すれば、より長期間に亘って展張可能な農業用塩化ビニル系樹脂フィルムを得ることが可能となる。
しかしながら、上記の構造単位を有するヒンダードアミン系化合物は、塩基性が強いため、硫黄化合物やハロゲン化合物によって活性を失い易い。すなわち、上記の農業用塩化ビニル系樹脂フィルムを展張した農業用施設内において、硫黄化合物やハロゲン化合物を含む農薬を使用した場合には、ヒンダードアミン系化合物が活性を失い、上記の効果が比較的短期間で消失してしまうという問題があった。
【０００６】
また、上記のヒンダードアミン系化合物を添加した農業用塩化ビニル系樹脂フィルムは、それを添加しない農業用塩化ビニル系樹脂フィルムと比較して、高周波ウエルダー適性が低下するという問題や、防滴持続性についても低下するという問題があった。
【０００７】
本発明は、上記した課題を解決するためになされたものであって、当該フィルムを展張した施設内にて硫黄化合物やハロゲン化合物を含む農薬を使用しても耐候性に優れ、また、高周波ウエルダー適性の低下や防滴持続性の低下も殆ど見られない、長期間展張可能な農業用塩化ビニル系樹脂フィルムを提供するものである。
【０００８】
【課題を解決するための手段】
上記課題を解決するためになされた本発明の農業用塩化ビニル系樹脂フィルムは、塩化ビニル系樹脂１００重量部当たり、化３に示す構造単位を一以上有するヒンダードアミン系化合物を単独で、０．０５〜３．０重量部添加してなる塩化ビニル系樹脂組成物をフィルム化してなることを特徴とするものである。

【００３０】
〔実施例１〜６、比較例１〜５〕
表１に示す配合からなる塩化ビニル系樹脂組成物を、ロール温度１８０℃のカレンダー装置を用いて、厚さ０．１ｍｍのフィルムに成形し、ポリ塩化ビニルフィルムを得た。

【表１】
以上の結果より明らかなように、本発明で特定するヒンダードアミン系化合物（ヒンダードアミン１）を単独で使用した実施例１〜３のフィルムは、そのフィルムを展張したハウス内で硫黄化合物を含む農薬やハロゲン化合物を含む農薬を使用しても耐候性に優れており、また、高周波ウエルダー適性の低下や防滴持続性の低下も抑制されている。また、本発明の特定するヒンダードアミン系化合物と従来より一般に使用されているヒンダードアミン系化合物（ヒンダードアミン２、３）を重量比で１：１の割合で併用した比較例６〜８のフィルムは、高周波ウエルダー適性の低下や防滴持続性の低下も抑制されているものの、本発明で特定するヒンダードアミン系化合物を単独で使用したものに比較して、そのフィルムを展張したハウス内で硫黄化合物を含む農薬やハロゲン化合物を含む農薬を使用したときの耐候性が劣る（但し、従来より一般に使用されているヒンダードアミン系化合物のみを使用したものと比較すると向上が見られる）ものである。従って、ハウス内で硫黄化合物を含む農薬やハロゲン化合物を含む農薬を使用したときの耐候性の低下を防ぐためには、本発明で特定するヒンダードアミン系化合物を単独で使用する必要があることがわかる。
【００３４】
【発明の効果】
以上詳述したように、本発明の農業用塩化ビニル系樹脂フィルムは、特定の構造単位を有するヒンダードアミン系化合物を添加してなるので、それを展張した農業用施設内でハロゲン化合物や硫黄化合物を含む農薬を使用しても、ヒンダードアミン系化合物の活性が損なわれず、また、従来のヒンダードアミン系化合物を使用したフィルムに見られる高周波ウエルダー適性の低下や防滴持続性の低下も殆ど見られないものである。[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an agricultural vinyl chloride resin film.
[0002]
[Prior art]
Conventionally, as a covering material for agricultural facilities such as houses and tunnels (hereinafter referred to as “agricultural covering material”), vinyl chloride resin film, polyethylene film, ethylene-vinyl acetate copolymer resin film, polyester film, or these A laminated film or the like is used. Among them, the vinyl chloride resin film is evaluated as having a good balance of various properties such as light transmittance, heat retention, mechanical strength, durability, workability when forming a film, and economy, and the above-mentioned agricultural use. Widely used as a covering material.
[0003]
[Problems to be solved by the invention]
In recent years, there has been a demand for an agricultural covering material that can be extended for a long period of time due to the shortage of farmers and resource saving.
Therefore, the above agricultural vinyl chloride resin film also has the structural unit shown in Chemical Formula 2 as a light stabilizer so as to improve weather resistance and to be able to be stretched over a long period of time. It has been proposed to add.
[0004]
[Chemical formula 2]
The above hindered amine compounds exhibit the effect of improving the weather resistance of agricultural vinyl chloride resin films and can be stretched over a longer period of time compared to agricultural vinyl chloride resin films that do not contain them. It becomes possible to obtain an agricultural vinyl chloride resin film.
However, the hindered amine compound having the above structural unit is strong in basicity and therefore easily loses its activity due to a sulfur compound or a halogen compound.

[0030]
[Examples 1-6, Comparative Examples 1-5]
A polyvinyl chloride resin composition having the composition shown in Table 1 was molded into a film having a thickness of 0.1 mm using a calendar device having a roll temperature of 180 ° C. to obtain a polyvinyl chloride film.
The resulting polyvinyl chloride film was evaluated for weather resistance, suitability for high-frequency welder, and drip-proof durability by the following methods. The results are shown in Table 1.
[0031]
(1) Weather resistance The obtained polyvinyl chloride film was spread on a tunnel house having a width of 1 m, a height of 80 cm and a length of 10 m, and the maximum elongation (Y) of the film after 20 months and From the maximum elongation (X) of the polyvinyl chloride film, the residual elongation rate was determined by the following formula and evaluated according to the following criteria.
However, pesticides containing halogen compounds were used once per month in the tunnel house, and pesticides containing sulfur compounds were used at a rate of 1/6 months.
[Expression 1]
5: Residual elongation is 80% or more 4: Residual elongation is 60% or more and less than 80% 3: Residual elongation is 40% or more and less than 60% 2: Residual elongation is 20% or more and less than 40% 1: Residual elongation Less than 20% (2) Suitability of high frequency welder Two polyvinyl chloride films obtained were fused and bonded using a high frequency welder sewing machine, and then visually observed for the state of the fused part when peeled off by hand And evaluated according to the following criteria.
[Standard]
5: No separation at the fusion part 4: Partial separation, but no separation at 2/3 or more in the fusion part 3: Separation at 1/3 or more and less than 2/3 in the fusion part Not 2: There was a part that did not peel off, but less than 1/3 in the fused part 1: The whole fused part was peeled off (3) Drip-proof sustainability Polyvinyl chloride film obtained, width 1m, height The film was extended to a tunnel house having a length of 80 cm and a length of 10 m, and the inner surface of the film after 20 months was visually observed and evaluated according to the following criteria.
[Standard]
5: Water droplets are not seen at all, and water flows in a film form 4: Fine water droplets are observed in a very small part, but water flows in a film form over almost the entire surface 3: Water droplets Part can be seen, and there are also places where water flows in a streak pattern 2: Many water droplets are seen, and water flows in a streak pattern 1: Water droplets adhere to almost the entire surface No flow at all [0032]
[Table 1]
As is clear from the above results, the films of Examples 1 to 3 using the hindered amine compound (hindered amine 1) specified by the present invention alone are agrochemicals and halogens containing sulfur compounds in the house where the film is stretched. Even if an agrochemical containing a compound is used, the weather resistance is excellent, and the deterioration of suitability for high-frequency welders and the drip-proof sustainability are also suppressed. The films of Comparative Examples 6 to 8 in which the hindered amine compound specified by the present invention and the hindered amine compounds (hindered amines 2 and 3) that have been conventionally used in general are used at a ratio of 1: 1 by weight are high frequency welders. Although the deterioration of the suitability and the drip-proof sustainability are also suppressed, compared with the one using the hindered amine compound specified in the present invention alone, the agricultural chemical containing the sulfur compound in the house where the film is stretched, The weather resistance when using an agrochemical containing a halogen compound is inferior (however, an improvement is seen in comparison with the one using only a hindered amine compound that has been generally used conventionally). Therefore, it can be seen that it is necessary to use the hindered amine compound specified in the present invention alone in order to prevent a decrease in weather resistance when an agricultural chemical containing a sulfur compound or an agricultural chemical containing a halogen compound is used in the house .
