Description
本発明は特定の構造を有するオルガノポリシロキサンを含む低起泡性の展着剤組成物に関するものである。 The present invention relates to a low-foaming spreader composition containing an organopolysiloxane having a specific structure.
除草、害虫駆除、病害予防等の目的で農作物へ農薬を散布する際に、農作物への農薬の付着状態が不均一であると薬効が低下してしまう。そして、散布してからできるだけ短時間のうちに、かつ均一に農薬を農作物に付着させ、雨が降る前に薬効成分を葉等の内部へ浸透させることを目的として、農薬水溶液、水性分散液等に界面活性剤を添加して、農薬水溶液、水性分散液等の表面張力を低下させる方法が一般に採用されている。 When agricultural chemicals are sprayed on crops for the purposes of weeding, pest control, disease prevention, etc., the efficacy of the agricultural chemicals on the crops will be reduced. And in the shortest possible time after spraying, the agricultural chemicals are uniformly attached to the crops, and the aqueous solution of the agricultural chemicals, aqueous dispersions, etc. for the purpose of allowing the medicinal ingredients to penetrate into the leaves before raining. In general, a method of reducing the surface tension of an agrochemical aqueous solution, an aqueous dispersion, or the like by adding a surfactant to is generally employed.
前記界面活性剤としては、通常、ポリオキシエチレンアルキルフェニルエーテル、ポリオキシエチレンアルキルエーテル、ポリオキシエチレン高級脂肪酸エステル等の非イオン系界面活性剤が使用され、また、低毒性であり界面活性力が高いという特性からシリコーン系界面活性剤が使用されている。これらの中でも、トリシロキサン骨格の主鎖を有する特定構造のポリエーテル変性シリコーンが最も界面活性力が高く、既に農薬用展着剤として実用化されている（特許文献１）。更に、該ポリエーテル変性シリコーンはｐＨが酸性あるいは塩基性である条件では界面活性力が低下するという欠点があったが、この欠点はシロキサン鎖の構造を変更することで改良されている（特許文献２）。 As the surfactant, nonionic surfactants such as polyoxyethylene alkylphenyl ether, polyoxyethylene alkyl ether, polyoxyethylene higher fatty acid ester and the like are usually used, and they have low toxicity and surface activity. Silicone surfactants are used because of their high properties. Among these, a polyether-modified silicone having a specific structure having a main chain of a trisiloxane skeleton has the highest surface activity and has already been put into practical use as a spreading agent for agricultural chemicals (Patent Document 1). Furthermore, the polyether-modified silicone has a drawback that the surface activity is lowered under the condition that the pH is acidic or basic, but this disadvantage is improved by changing the structure of the siloxane chain (Patent Document). 2).
しかし、これらの展着剤を添加した農薬水溶液、水性分散液等は表面張力が低下するため泡立ちやすくなる。そのため、農薬水溶液、水性分散液等を調製する際には、更に、泡立ち防止の目的で消泡剤が添加されているが、これらの農薬用展着剤、特にポリエーテル変性シリコーンは界面活性力が高いため、消泡剤を添加しても泡立ちを完全に抑えることは困難であった。 However, agrochemical aqueous solutions, aqueous dispersions, and the like to which these spreading agents are added tend to foam because the surface tension is lowered. Therefore, when preparing an agrochemical aqueous solution, an aqueous dispersion, etc., an antifoaming agent is further added for the purpose of preventing foaming, but these spreading agents for agricultural chemicals, particularly polyether-modified silicones, have surface activity. Therefore, it was difficult to completely suppress foaming even when an antifoaming agent was added.
さらに、十分な効果を発揮するまで消泡剤を多量に添加すると、展着剤や農薬自体の効果を阻害するおそれがあるため好ましくない。このため、界面活性力が高く泡立ちの少ない農薬用展着剤が求められていた。 Furthermore, it is not preferable to add a large amount of an antifoaming agent until a sufficient effect is exhibited, since the effects of the spreading agent and the agricultural chemical itself may be hindered. For this reason, a spreading agent for agricultural chemicals having high surface activity and less foaming has been demanded.
本発明は、高い界面活性力を有し、かつ低起泡性である、農薬用の展着剤組成物を提供することにある。 An object of the present invention is to provide a spreading agent composition for agricultural chemicals having high surface activity and low foaming property.
