【産業上の利用分野】
本発明は、消泡剤組成物に関する。さらに詳しくは、抑泡持続性を低下させずに初期破泡性を向上させた引火危険性の小さい紙パルプ工業、食品工業、石油工業、繊維工業、塗料工業、化学工業、廃棄物処理などの工程および排水処理工程で利用できる消泡剤組成物に関するものである。
【0002】
【従来の技術】
ポリエーテル系消泡剤は、他種消泡剤に比較して様々な優れた性質を持っているので紙パルプ工業、食品工業、石油工業、繊維工業、塗料工業、化学工業、廃棄物処理など発泡をともなう工業に広く使用されている。
各種工業において発泡の原因となる物質を含む系に対し温度、PH、設備等の物理的あるいは化学的要因が加わり発泡を誘発し、製品品質の低下、生産効率の低下、原料のロスといった事態を招くことが度々ある。そこでこれらの問題解決のため必要に応じて消泡剤の添加がなされている。
【0003】
ポリエーテル系消泡剤として高級アルコールにアルキレンオキシドを付加させたものや更に脂肪酸などでエステル化したもの(特公昭50−5157号、特公昭49−38923号、特公昭50−1475号各公報)、ポリオキシアルキレンを脂肪酸でエステル化したもの(特公昭45−7973号公報)、またポリオキシアルキレンの金属塩にハロゲン化アルキルを反応させエーテル結合を形成させたもの(特開昭50−4282号、特開平2−289526号各公報)などが知られている。
【0004】
また、初期破泡性、抑泡持続性を向上させる目的でアルキレンオキシド被付加物質の種類、アルキレンオキシドの種類、アルキレンオキシドの付加する位置または量または順序などに工夫すべき点が特公昭41−7439号、特公平6−79642号、特開昭56−169583号、特開昭52−83408号、特開昭57−119807号、特開昭59−132908号、特開昭60−7908号、特開昭61−178005、特開昭61−293508号および特開昭62−250917号各公報に記載されている。
【0005】
【発明が解決しようとする課題】
アルキレンオキシドの種類、付加する位置、量または順序を変えて初期破泡性または抑泡持続性を改善する方法では、エチレンオキシドの分子全体に占める割合が大きい程、また、分子の末端に近づく程初期破泡性に優れたものとなる反面、抑泡持続性に劣る欠点があった。一方、エチレンオキシドの分子全体に占める割合が小さい程、また、分子の末端より遠い程、抑泡持続性に優れるが、初期破泡性に劣るという欠点があった。したがって、従来、初期破泡性および抑泡持続性の両者を同時に満足するポリエーテル系消泡剤を得ることは極めて困難であった。このように従来のポリエーテル系消泡剤は、初期破泡性と抑泡持続性のいずれかを改善しようとするものであり、これらを同時に改善し得るものはなかった。
また、これら従来のポリエーテル系消泡剤は引火危険性があり使用、保管および運搬上安全性に劣るという問題点があった。

[Industrial application fields]
The present invention relates to an antifoam composition. In more detail, such as pulp and paper industry, food industry, petroleum industry, textile industry, paint industry, chemical industry, waste disposal, etc. with low flammability, which has improved initial foam resistance without lowering foam sustainability The present invention relates to an antifoaming agent composition that can be used in processes and wastewater treatment processes.
[0002]
[Prior art]
Polyether antifoaming agents have various superior properties compared to other types of antifoaming agents, so the pulp and paper industry, food industry, petroleum industry, textile industry, paint industry, chemical industry, waste treatment, etc. Widely used in industries with foaming.
In various industries, physical or chemical factors such as temperature, pH, equipment, etc. are added to systems containing substances that cause foaming to induce foaming, resulting in product quality degradation, production efficiency degradation, and raw material loss. I often invite. Therefore, an antifoaming agent is added as necessary to solve these problems.
[0003]
Polyether-based antifoaming agents obtained by adding an alkylene oxide to a higher alcohol or esterified with a fatty acid or the like (Japanese Patent Publication Nos. 50-5157, 49-38923, and Japanese Patent Publication No. 50-1475) Polyoxyalkylene esterified with a fatty acid (Japanese Patent Publication No. 45-7793), or polyoxyalkylene metal salt reacted with an alkyl halide to form an ether bond (Japanese Patent Laid-Open No. 50-4282) JP-A-2-289526, etc.) are known.
[0004]
In addition, for the purpose of improving the initial foam breaking property and foam suppression sustainability, the kind of alkylene oxide adduct, the kind of alkylene oxide, the position or amount or order of addition of alkylene oxide, etc. should be devised. 7439, JP-B-6-79642, JP-A-56-169583, JP-A-52-83408, JP-A-57-1119807, JP-A-59-132908, JP-A-60-7908, These are described in JP-A 61-178005, JP-A 61-293508 and JP-A 62-250917.
[0005]
[Problems to be solved by the invention]
In the method of improving the initial bubble-breaking property or foam-holding durability by changing the type, position, amount or order of alkylene oxide, the larger the proportion of ethylene oxide in the whole molecule, the closer to the end of the molecule On the other hand, it had excellent foam breaking property, but it had the disadvantage of poor foam retention. On the other hand, the smaller the proportion of ethylene oxide in the whole molecule, and the farther from the end of the molecule, the better the antifoaming sustainability, but the lower the initial foam breaking property. Therefore, conventionally, it has been extremely difficult to obtain a polyether-based antifoaming agent that satisfies both the initial foam breaking property and the foam sustaining property at the same time. As described above, the conventional polyether antifoaming agent is intended to improve either the initial foam breaking property or the antifoaming sustainability, and none of them can improve these simultaneously.
Further, these conventional polyether antifoaming agents have a risk of ignition and are inferior in safety in use, storage and transportation.
[0006]
[Means for Solving the Problems]
An object of the present invention is to provide an antifoaming agent composition that improves the initial foam breaking property without lowering the foam suppression sustainability and has a low risk of ignition. That is, the antifoaming composition of the present invention comprises 60 to 99 parts by weight of one or more polyoxyalkylene compounds represented by the following formula (1) having an average molecular weight of 200 to 10,000, It is characterized by comprising 40 parts by weight, and if necessary, the solubilizer is added in an amount of 0.1 to 100 parts by weight with respect to 100 parts by weight of the composition, wherein the amount of water is 1 to 30 parts by weight. 20 parts by weight can be added.

[0007]
The average molecular weight of the polyoxyalkylene compound represented by the formula (1) is 200 to 10000, preferably 300 to 7000, particularly preferably 500 to 4000.
