Abstract
Description
本発明は、消泡剤組成物に関する。 The present invention relates to antifoam compositions.
従来から、製紙パルプ工業、塗料工業、繊維工業、合成樹脂工業、樹脂エマルジョン工業、セメント・コンクリート工業、食品工業及び発酵工業等の製造工程や、屎尿処理及び廃水処理等の処理工程においては、発泡障害のために生産性、処理能力の低下が問題になっている。特に近年は、前記の工業分野の製造・処理工程に分散剤、脱墨剤、サイズ剤、及びラテックス等の発泡の原因になる物質が多く用いられる傾向にあり、従来以上に発泡が問題になっている。このような発泡を防止するため、従来から様々な消泡剤が提案されており、例えば、一般的には、高級アルコール系エマルション消泡剤、又はシリコーン系消泡剤が使用されている。 Foaming has traditionally been used in manufacturing processes such as the paper and pulp industry, paint industry, textile industry, synthetic resin industry, resin emulsion industry, cement and concrete industry, food industry, and fermentation industry, as well as treatment processes such as human waste treatment and wastewater treatment. The problem is a decline in productivity and processing capacity due to the failure. Particularly in recent years, there has been a tendency for substances that cause foaming, such as dispersants, deinking agents, sizing agents, and latex, to be increasingly used in manufacturing and processing processes in the above-mentioned industrial fields, and foaming has become more of a problem than ever before. ing. In order to prevent such foaming, various antifoaming agents have been proposed in the past, and for example, higher alcohol emulsion antifoaming agents or silicone antifoaming agents are generally used.
特開2003-71207号公報(特許文献1)には、高級アルコール系エマルション消泡剤において、ウエランガム及び/又は構成単糖がモル比でフコース:グルコース:グルクロン酸:ラムノース=1~2:1~4:1~2:1~2である多糖類と、ザンサンガムと、ナトリウムカルボキシメチルセルロース、ヒドロキシエチルセルロース、ヒドロキシプロピルメチルセルロースの中から選ばれた少なくとも1種、を含むことを特徴とするエマルション安定性が改善された高級アルコール系エマルション消泡剤が開示されている。しかしながら、高級アルコール系エマルション消泡剤においてはエマルション相分離、増粘・ゲル化が発生し十分な消泡効果が発揮されないという問題があった。 JP-A No. 2003-71207 (Patent Document 1) discloses that in a higher alcohol emulsion antifoaming agent, welan gum and/or constituent monosaccharides have a molar ratio of fucose: glucose: glucuronic acid: rhamnose = 1 to 2:1. Improved emulsion stability characterized by containing a polysaccharide having a ratio of 4:1 to 2:1 to 2, xanthan gum, and at least one selected from sodium carboxymethylcellulose, hydroxyethylcellulose, and hydroxypropylmethylcellulose. A higher alcohol-based emulsion antifoaming agent is disclosed. However, higher alcohol-based emulsion antifoaming agents have the problem that emulsion phase separation, thickening, and gelation occur, and a sufficient antifoaming effect is not exhibited.
また、特開2001-212403号公報(特許文献2)には、消泡性成分としてシリコーン系ブロック交互共重合体、微粉末無機化合物、乳化剤および水を含有する水中油型エマルジョンのシリコーン系消泡剤が開示されている。しかしながら、消泡性成分としてシリコーン系ブロック交互共重合体は、分散性が悪く、消泡効果が低下する恐れがあり、また、製紙パルプ工業に使用した場合、シリコーン系ブロック交互共重合体が部分的に小滴となり小斑点となる、いわゆるオイルスポットによって、得られる紙の品質を著しく損なう恐れがあり、そのことによる印刷適正が十分ではないという問題があった。 Furthermore, JP-A-2001-212403 (Patent Document 2) describes a silicone-based antifoaming agent for an oil-in-water emulsion containing a silicone-based block alternating copolymer, a finely powdered inorganic compound, an emulsifier, and water as an antifoaming component. Agents are disclosed. However, silicone-based alternating block copolymers as anti-foaming components have poor dispersibility and may reduce the anti-foaming effect. There is a risk that so-called oil spots, which turn into small droplets and small spots, can significantly impair the quality of the paper obtained, and this poses a problem in that the printing suitability is not sufficient.
本発明は、上記従来技術の有する課題に鑑みてなされたものであり、発泡液に添加した場合に、初期消泡性と消泡持続性との双方の消泡性に優れており、かつ、紙パルプ製造工業の抄紙工程用消泡剤として使用した場合に、前記消泡性に加えて、得られる紙パルプのサイズ度の低下を十分に抑制することが可能な消泡剤組成物を提供することを目的とする。 The present invention has been made in view of the problems of the prior art described above, and has excellent defoaming properties in both initial defoaming properties and sustained defoaming properties when added to a foaming liquid, and Provided is an antifoaming composition that, when used as an antifoaming agent for the papermaking process in the paper pulp manufacturing industry, not only has the above-mentioned antifoaming properties but also can sufficiently suppress a decrease in the size of the resulting paper pulp. The purpose is to
本発明者らは、上記目的を達成すべく鋭意研究を重ねた結果、レシチンと、特定の界面活性剤とを用いることによって、前記目的を達成することが可能な消泡剤組成物が得られることを見出し、本発明を完成するに至った。 As a result of extensive research to achieve the above object, the present inventors have found that an antifoam composition capable of achieving the above object can be obtained by using lecithin and a specific surfactant.

〔Device〕
A foaming test liquid was filled inside a cylindrical glass cylinder device (inside Φ100 mm, outside Φ130 mm, height 1000 mm) with a double structure and the bottom closed with a rubber stopper, and a pump (manufacturer: Iwaki Co., Ltd.) was used. A device that generates foam by sucking up the foaming test liquid from the bottom of the device to the top of the device, dropping it, and circulating it. This device circulates a heating medium between the outside and inside of the glass cylinder to maintain a constant temperature during the test. The liquid level drop from the top of the device was 600 mm, and the nozzle diameter at the outlet of the foaming test liquid was Φ8 mm.
〔試験方法〕
ガラス製シリンダーの上部の管からガラス製シリンダー内の液面に循環液を落下させることで発泡を促し、液面からの泡上部までの高さを測定し、消泡性を評価した。
〔Test method〕
Foaming was promoted by dropping the circulating liquid from the tube at the top of the glass cylinder onto the liquid surface inside the glass cylinder, and the height from the liquid surface to the top of the bubbles was measured to evaluate defoaming performance.
〔試験条件〕
ガラス製シリンダーに発泡試験液1又は2を1L入れ、40℃に温調した。ポンプにて循環すると同時にマイクロピペット(GILSON社製、容量200μl)にて所定量の消泡剤をイオン交換水で希釈した液を添加した。次に、循環流量5L/分にて循環し、30秒後、5分後の泡高さを測定した。30秒後の泡高さが初期消泡性を表し、5分後の泡高さが消泡持続性を表す。泡の高さが低いほど消泡性が高い。
〔Test conditions〕
1 L of foaming test liquid 1 or 2 was placed in a glass cylinder, and the temperature was adjusted to 40°C. While circulating with a pump, a predetermined amount of antifoaming agent diluted with ion-exchanged water was added using a micropipette (manufactured by GILSON, volume: 200 μl). Next, the mixture was circulated at a circulation flow rate of 5 L/min, and the foam height was measured after 30 seconds and 5 minutes. The foam height after 30 seconds represents the initial defoaming property, and the foam height after 5 minutes represents the durability of defoaming. The lower the foam height, the higher the defoaming property.
