本発明は随道構築時に裏込め材として用いられるモルタ
ルの起泡剤に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a foaming agent for mortar used as a backfilling material when constructing a road.
隙道構築時に用いられる裏込め材の凝結後の強度は、隙
道の用途や地質等によって規定されるが、一般に高い強
度を要求されないことから、セメント含有率の低いモル
タルを起泡剤を用いて高率に起泡させたエアーモルタル
が良く用いられる。The strength of the backfill material used when constructing a tunnel after setting is determined by the purpose of the tunnel, geology, etc., but generally high strength is not required, so mortar with a low cement content is used with a foaming agent. Air mortar that has been foamed at a high rate is often used.
エアーモルタルの特性には、強度以外にも気泡連行性、
気泡率と気泡経時安定性、高流動性等が要求され、これ
等の特性は起泡剤によるところが大きい。In addition to strength, the characteristics of air mortar include bubble entrainment,
Cell ratio, cell stability over time, high fluidity, etc. are required, and these characteristics largely depend on the foaming agent.
従来、エアーモルタルの起泡剤として、アルキルベンゼ
ンスルフォン酸塩
ル塩、アルキルおよびアルキルアリルエトキシレート、
アルキルおよびアルキルアリルエトキシレート硫酸エス
テル塩等の界面活性剤の１種または２種以上の混合物を
エアーモルタル用起泡剤として用いてきた。Traditionally, as blowing agents for air mortars, alkylbenzene sulfonate salts, alkyl and alkylaryl ethoxylates,
One or a mixture of two or more surfactants, such as alkyl and alkylaryl ethoxylate sulfate salts, have been used as blowing agents for air mortars.
しかし、これ等の界面活性剤は起泡剤として使用しても
、モルタルの気泡率や気泡経時安定性が充分でなく、比
較的多量を必要とし、必然的にエアーモルタルの凝結遅
延や、強度低下等の障害を起し易い等の欠点を有する。However, even when these surfactants are used as foaming agents, they do not have a sufficient foam rate or foam stability over time, and a relatively large amount is required, which inevitably delays the setting of air mortar and increases the strength of the air mortar. It has drawbacks such as being susceptible to problems such as deterioration.

粉、アルギン酸ソーダ等の水溶性糊剤を併用することも
実施されている。For the purpose of improving the cell ratio and cell stability over time, the use of a water-soluble sizing agent such as polyvinyl alcohol, hydroxypropyl cellulose, methyl cellulose, carboxymethyl cellulose, starch, or sodium alginate in combination with a surfactant has also been carried out.
界面活性剤と糊剤を併用した起泡剤はモルタルの起泡率

ルタルの特性である高流動性が損なわれたり、凝結遅延

剤と糊剤を混合した起泡剤では粘性が高くなり、取扱い
が困難になる等の欠点を有する。A foaming agent that uses a combination of a surfactant and a sizing agent can improve the foaming rate and foam stability of mortar over time, but it may impair the high fluidity that is the characteristic of air mortar, delay setting, and reduce strength. Furthermore, a foaming agent that is a mixture of a surfactant and a sizing agent has a drawback that it becomes highly viscous and difficult to handle.
また、炭素数９〜１５の合成アルコール硫酸エステル塩
をモルタル起泡剤として用いられることが知られている
が、低温時の性能低下現象があり、側鎖アルコール含有
率４０〜６０重量％と細かく限定する必要があり、さら
には水溶解性に劣り、高濃度起泡剤とすることが極めて
困難である等の欠点を有する。In addition, it is known that synthetic alcohol sulfate ester salts having 9 to 15 carbon atoms are used as mortar foaming agents, but the performance deteriorates at low temperatures, and the side chain alcohol content is 40 to 60% by weight. Furthermore, it has disadvantages such as poor water solubility and extremely difficulty in forming a high-concentration foaming agent.
本発明者は、鋭意研究の結果、従来のエアーモルタル用
起泡剤の種々の欠点を解消して、優れた裏込め材用モル

起泡剤を提供するものである。That is, an alcohol having a side chain in an alkyl group has 15
Synthetic alcohol with a carbon number of 7 to 11, containing at least % by weight.
The present invention provides a foaming agent for mortar for backfilling material, which contains a sulfuric acid ester salt of an ethylene oxide adduct (number of moles added: 1 to 10) as an essential component.
本発明に用いるアルコールの側鎖率は高い方が好
塩にした時の低温における溶解性に劣り、高濃度の起泡

There are synthetic alcohols such as ethylhexanol.
オキソ法で得られる合成アルコールは反応条件や触媒の

まま使用できるが、炭素数７〜１１の合成アルコールの
含有率は７０％以上であることが特に好ましい。Synthetic alcohol obtained by the oxo method is usually commercially available as a mixture of alcohols with a certain number of carbon atoms, so it can be used as it is, but it is particularly preferable that the content of synthetic alcohol with a carbon number of 7 to 11 is 70% or more. .
本発明化合物に使用する合成アルコール中に炭素数１２
以上のアルコールの比率が３０重量％を越えると起泡性

ことはできない。12 carbon atoms in the synthetic alcohol used for the compound of the present invention
If the ratio of the above alcohols exceeds 30% by weight, the foaming properties will decrease, and unless a large amount is added, the effects of the present invention cannot be achieved.
また、炭素数６以下のアルコールが３０重量％を越える
と気泡率、気泡経時安定性も低下するので好ましくない
。Furthermore, if the content of alcohol having 6 or less carbon atoms exceeds 30% by weight, it is not preferable because the cell ratio and cell stability over time will also decrease.
２−エチルヘキサノールは単独の炭素数アルコールとし

ソ法合成アルコールと併用することが好ましい。Although 2-ethylhexanol can be obtained as a single alcohol having a carbon number, it is preferably used in combination with an alcohol having a different number of carbon atoms, such as an oxo-synthesized alcohol.
本発明化合物中のエチレンオキサイド付加モル数は１〜
１０が好ましく、０では低温安定性に劣り、水溶解性も
低いので、高濃度起泡剤を調製することが難しい。The number of moles of ethylene oxide added in the compound of the present invention is 1 to
A value of 10 is preferred; a value of 0 results in poor low temperature stability and low water solubility, making it difficult to prepare a highly concentrated foaming agent.
１０以上になるとエアーモルタルの気泡経時安定性が低
下し、また、気泡率も劣るので好ましくない。If it exceeds 10, the stability of the bubbles in the air mortar over time will decrease, and the bubble rate will also be poor, which is not preferable.

が良くなるが気泡率は低く、また、エアーモルタルの流
動性を示すフロー値も低い。Dopanol 25 (EO) 5 sulfate ester soda salt and HP
The mixtures of C (sample Nos. 15 to 17) have good bubble stability over time, but have a low bubble rate and also have a low flow value, which indicates the fluidity of air mortar.
実施例 ２
ミキサーに所定量の水と起泡剤を入れ、低速回転で１分
間攪拌混合する。Example 2 A predetermined amount of water and a foaming agent are placed in a mixer and stirred and mixed at low speed for 1 minute.
次にＦＣＰ−１（木節系市販粘土：昌栄産業製）１００
０ｇを入れ、２分間低速回転で練った後、普通ポルトラ
ンドセメント１０００ｇを入れ、高速回転で２分間練り
まぜたときのエアーモルタルの特性を測定し、その結果
を第２表に示す。Next, FCP-1 (Kibushi-based commercially available clay: manufactured by Shoei Sangyo) 100
0g was added and kneaded at low speed for 2 minutes, then 1000g of ordinary Portland cement was added and kneaded at high speed for 2 minutes.The characteristics of the air mortar were measured.The results are shown in Table 2.
（注）１．起泡剤添加量は対セメント（％）を示す。(Note) 1. The amount of foaming agent added is based on cement (%).
２、ドパノール４５は炭素数１４〜１５を主成分とする
三菱油化製オキソ法合成アルコールで側鎖率約２０％で
ある。2. Dopanol 45 is an oxo-method synthesized alcohol manufactured by Mitsubishi Yuka Co., Ltd. whose main component has 14 to 15 carbon atoms and has a side chain ratio of about 20%.
第２表に示すとおり、本発明化合物（供試Ｎｏ、１〜６
）は、市販粘土系エアーモルタルにおいても優れた気泡
率が得られ、また、気泡の経時安定性も高いことが確認
できる。As shown in Table 2, the compounds of the present invention (sample Nos. 1 to 6)
) can be confirmed to have an excellent cell ratio even in commercially available clay-based air mortar, and also to have high cell stability over time.
