合成樹脂フィルム組成物に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an antifogging synthetic resin film composition for agricultural films used in greenhouses or tunnels. More specifically, the present invention relates to an antifogging synthetic resin film composition that has excellent initial antifogging properties immediately after the film is used and excellent sustained antifogging properties at high temperatures.
近年、農作物の早期育成又は季節外育成を目的として、
合成樹脂フィルムを使用した農業用ハウス、トンネル等
の中での作物栽培が広く行われている。In recent years, for the purpose of early or out-of-season cultivation of crops,
Crop cultivation in agricultural greenhouses, tunnels, etc. using synthetic resin films is widely practiced.
しかし、これらの合成樹脂フィルムは、フィルム表面が

。However, since the surface of these synthetic resin films is hydrophobic, if they are used as is, water vapor evaporated from the ground surface in agricultural greenhouses, tunnels, or from crops will condense on the film surface and adhere as water droplets. The film surface becomes foggy without showing any so-called wetting phenomenon. As a result, the penetration of sunlight becomes poor and the rate of temperature rise inside the heat insulation greenhouse decreases, significantly inhibiting the growth of crops.
これらの問題を解決するため、現在行われている方法は

ム表面を元来の疎水性から親水性へ変える方法である。In order to solve these problems, the current method is to incorporate an antifogging agent consisting mainly of nonionic surfactants when molding synthetic resin products to restore the film surface to its original state. This is a method of changing from hydrophobic to hydrophilic.

くなる性質のものである。Since the antifogging agent performs the function of making the surface hydrophilic, it is essential that it be present near the film surface. On the other hand, because of this, the antifogging agent is gradually lost due to the surface becoming sticky and being damaged by falling water, and its effectiveness deteriorates over time.

用して用いる事が多い。The most widely used antifogging agents at present are sorbicun higher fatty acid esters (Japanese Patent Publication No. 4G-31748) and their ethylene oxide adducts (Japanese Patent Publication No. 559431) or propylene oxide adducts (Japanese Patent Publication No. 4L-31748).
). In general, sorbitan higher fatty acid esters have poor initial antifogging properties but are excellent in sustained antifogging properties, while ethylene oxide adducts or propylene oxide adducts have excellent initial antifogging properties but have excellent sustained antifogging properties. It has a tendency to be inferior in terms of texture and stickiness. Therefore, in reality, these are often used in combination.

る。In order to even out the growth of agricultural crops more efficiently, we have improved the initial anti-fogging properties compared to the current level, and for economic reasons, we have developed sustainable anti-fogging properties in order to be able to use the same film for a long period of time. It is always desirable to improve. If an attempt is made to improve the film by simply adding an increased amount of antifogging agent, the film becomes sticky and the transparency deteriorates, which is not preferable. Therefore, there is a strong desire for antifogging that improves initial antifogging properties and sustained antifogging properties and does not have drawbacks in terms of transparency or stickiness.

The object of the present invention was to discover a synthetic resin film composition that has long-lasting and long-term antifogging effects, good transparency, and no stickiness.

ルの比率を高くする事が行なわれている。In general, Defense 112 WII. ! :In order to utilize polyhydric alcohol fatty acid partial esters, it is desirable to have a high content of monoesters and diesters (Theory and practice of L-plastic compounding agents,” Plastic Age P83-85, Japanese Patent Publication No. 62-101251. Reaction composition of partial alcohol fatty acid ester (freeboliol/monoester/
Diesters/triesters...) are known to follow a probability distribution ([Food-use emulsifiers] Saiwai Shobo P16

題点をｆｒ Ｌている。However, in the case of pentaerythritol or dipentaerythritol fatty acid partial ester, which is one of polyhydric alcohol fatty acid partial esters, pentaerythritol or dipentaerythritol has a high melting point (IH°C or higher).
Therefore, especially when the esterification rate is low (for example, 1 to 1.5 moles of fatty acid is esterified per 1 mole of polyhydric alcohol), in the product production process, the reactants must be kept at a temperature below the melting point of these polyols. When the reactant system is maintained at . That is, free polyol increases, monoester decreases, and high esters such as tri, tetra, etc. increase. For this reason, there is a problem that it is difficult to obtain the desired composition.

It also occurs noticeably when ethylene oxide is added to pentaerythritol fatty acid partial ester or dipentaerythritol fatty acid partial ester at a reaction temperature of 120 to 160°C and an alkaline catalyst. Therefore, the addition of ethylene oxide to the same ester, especially about 0.2 to 4 mol of ethylene oxide to 1 mol of pentaerythritol or 0.4 to 8 mol of ethylene oxide to 1 mol of dipentaerythritol, is recommended. It is usually difficult to easily obtain low molar ethylene oxide adducts.

を完成した。As a result of intensive studies, the present inventors found that when the ethylene oxide adduct of pentaerythritol and/or dipentaerythritol obtained by the method of the above-mentioned patent is esterified with a higher fatty acid, the melting point of the free polyol decreases, Due to increased compatibility with esters, ethylene oxide adducts of pentaerythritol fatty acid partial esters and/or dipentaerythritol fatty acid partial esters have compositions that do not deviate from the previously unimaginable probability distribution. We found that the following can be obtained, and furthermore, these

The film was stretched and fixed with a rubber band and placed in a thermostatic chamber at 0°C, and the degree of water droplet adhesion was evaluated using a five-point scale: ◎, ○, △, X, and XX.
◎は表面が均一に濡れ水滴を全く認めない状態。××は
全面に小さな水滴が付着している状態。○〜△はそれら
の中間の状態。◎ means the surface is uniformly wet and no water droplets are observed. XX is a state in which small water droplets are attached to the entire surface. ○～△ are intermediate states.

。0.0% ethylene carbonate per mole of pentaerythritol.
The transparency of the product e of the present invention with 2 moles added is better than that of the pentaerythritol ester without the addition (comparative product b).
This is worse than the ester with 1 mole or more added (inventive product f.j), and in this sense, it is clear that the number of moles of ethylene carbonate added needs to be limited to 0.5 mole or more.
