Abstract
Description
本発明は、構造物の止水材及び止水工法に関するものであり、より詳細には、土木建築分野において貯水槽、下水管、地下鉄やトンネルなどのコンクリート構造物の目地や亀裂部に充填して漏水を補修するためのグラウト材として用いられる構造物の止水材と、この止水材を用いた構造物の止水工法に関するものである。 The present invention relates to a waterproofing material and a waterproofing method for a structure, and more particularly, in the field of civil engineering and construction, filling joints and cracks in concrete structures such as water storage tanks, sewer pipes, subways and tunnels. The present invention relates to a waterproofing material for a structure used as a grout material for repairing water leakage and a waterproofing method for a structure using the waterproofing material.
コンクリート構造物は、温度や湿度の変化、乾燥収縮、アルカリ骨材反応、あるいは地震などの外力などにより、空隙や亀裂が生じやすく、その部分からの漏水が問題となっている。 In concrete structures, voids and cracks are likely to occur due to changes in temperature and humidity, drying shrinkage, alkali-aggregate reaction, or external forces such as earthquakes.
従来、この種の補修には、水ガラス系、セメント系および水和反応型ウレタンなどの材料が使用されている。しかしながら、これらの材料は耐久性に劣ることから、半永久的な止水効果を得ることは困難であり、再度の補修が必要であった。 Conventionally, materials such as water glass, cement, and hydration type urethane are used for this type of repair. However, since these materials are inferior in durability, it is difficult to obtain a semi-permanent water-stopping effect, and repair is necessary again.
そこで、耐久性に優れる止水剤として、発泡ウレタン型材料が提案されている。特許文献1〜4には、このような発泡ウレタン型材料を用いた止水材が開示されている。しかしながら、これらの材料も、水中に長期間浸漬した場合には、硬化物が収縮することにより止水効果が得られなくなるという問題があった。 Therefore, a urethane foam type material has been proposed as a waterproofing agent having excellent durability. Patent Documents 1 to 4 disclose a waterstop material using such a foamed urethane type material. However, when these materials are also immersed in water for a long period of time, there is a problem that the water-stopping effect cannot be obtained due to shrinkage of the cured product.
本発明は、上記のような問題点を解決するためになされたものであり、確実に構造物の亀裂などを閉塞し、構造物の漏水を止めることのできる止水材であって、長期耐久性が従来より向上し、よって信頼性の高い止水材を提供することを目的とする。また、この止水材を用いた止水効果の持続性に優れた止水工法を提供することを目的とする The present invention has been made to solve the above-described problems, and is a water-stop material that can reliably block the cracks of the structure and stop the leakage of the structure, and has a long-term durability. The purpose of the present invention is to provide a highly reliable water-stopping material. Moreover, it aims at providing the water stop construction method excellent in the sustainability of the water stop effect using this water stop material.

Preferred is a terminal isocyanate group-containing urethane prepolymer.
本発明に用いられる3級アミン触媒(B)は公知のものを特に制限なく用いることができ、例としては、N,N−ジメチルオクチルアミン、N,N−ジメチルラウリルアミン、N,N,N’,N’−テトラメチルヘキサメチレンジアミン、N,N,N’,N’−テトラメチルプロピレンジアミン、N,N,N’,N’−テトラメチルエチレンジアミン、N,N,N’,N’,N’’−ペンタメチルジエチレントリアミン、トリメチルアミノエチルピペラジン、ビス−(ジメチルアミノエチル)エーテル、ヘキサヒドロ−S−トリアジン、2−メチルトリエチレンジアミン、N,N−ジメチルアミノエチルモルホリン、ジメチルアミノプロピルイミダゾール、ヘキサメチルトリエチレンテトラミン、ヘキサメチルトリプロピレンテトラミン、N,N,N−トリス(3−ジメチルアミノプロピル)アミンなどが挙げられ、これらは単独、もしくは2種以上併せて用いることができる。 As the tertiary amine catalyst (B) used in the present invention, a known one can be used without particular limitation. Examples thereof include N, N-dimethyloctylamine, N, N-dimethyllaurylamine, N, N, N. ', N'-tetramethylhexamethylenediamine, N, N, N', N'-tetramethylpropylenediamine, N, N, N ', N'-tetramethylethylenediamine, N, N, N', N ', N ″ -pentamethyldiethylenetriamine, trimethylaminoethylpiperazine, bis- (dimethylaminoethyl) ether, hexahydro-S-triazine, 2-methyltriethylenediamine, N, N-dimethylaminoethylmorpholine, dimethylaminopropylimidazole, hexamethyl Triethylenetetramine, hexamethyltripropylenetetramine, N, , N- tris (3-dimethylaminopropyl) amine and the like, which may be used in combination either alone, or two or more kinds.
3級アミン触媒(B)の配合量は、有機ポリイソシアネート化合物(A)100重量部に対して0.1〜20重量部が好ましく、より好ましくは0.5〜10重量部の範囲内で設定される。0.1部よりも少ない場合には有機ポリイソシアネート化合物(A)と水との発泡硬化反応が進みにくい傾向にあり、20部よりも多い場合には発泡硬化反応が非常に早くなることから、亀裂の細部まで止水材が浸透しなくなる傾向がある上、3級アミン触媒(B)が比較的高価なため、経済性に欠ける。 The blending amount of the tertiary amine catalyst (B) is preferably 0.1 to 20 parts by weight, more preferably 0.5 to 10 parts by weight with respect to 100 parts by weight of the organic polyisocyanate compound (A). Is done. When the amount is less than 0.1 part, the foam curing reaction between the organic polyisocyanate compound (A) and water tends to be difficult to proceed. When the amount is more than 20 parts, the foam curing reaction becomes very fast. There is a tendency that the water-stopping material does not penetrate to the details of the cracks, and the tertiary amine catalyst (B) is relatively expensive, so that it is not economical.
シリコーン整泡剤(C)は、均一なセル構造を持つフォームとするために用いられる。シリコーン整泡剤(C)の例としては、硬質発泡ウレタン樹脂に通常用いられるポリオキシアルキレンジメチルポリシロキサンコポリマーが挙げられる。 The silicone foam stabilizer (C) is used to form a foam having a uniform cell structure. Examples of the silicone foam stabilizer (C) include polyoxyalkylene dimethyl polysiloxane copolymers usually used for rigid foamed urethane resins.
シリコーン整泡剤(C)の配合量は、通常、有機ポリイソシアネート化合物(A)100重量部に対して0.1〜2重量部の範囲内で設定される。 The compounding quantity of a silicone foam stabilizer (C) is normally set in the range of 0.1-2 weight part with respect to 100 weight part of organic polyisocyanate compound (A).
アセチルクエン酸トリアルキル(D)としては、アセチルクエン酸トリプロピル、アセチルクエン酸トリブチル、アセチルクエン酸トリペンチル、アセチルクエン酸トリヘキシルが挙げられる。アセチルクエン酸トリアルキル(D)を用いることにより、止水材と水との相溶性が優れるとともに、硬化物からの有機成分溶出量の低減や硬化物の収縮防止という効果を奏する。これらのうち、アルキル基の炭素数が3〜6であるものが好ましく、アセチルクエン酸トリブチルが特に好ましい。 Examples of the trialkyl acetyl citrate (D) include tripropyl acetyl citrate, tributyl acetyl citrate, tripentyl acetyl citrate, and trihexyl acetyl citrate. By using trialkyl acetyl citrate (D), the compatibility between the water-stopping material and water is excellent, and the effects of reducing the amount of organic components eluted from the cured product and preventing shrinkage of the cured product are exhibited. Among these, the alkyl group having 3 to 6 carbon atoms is preferable, and tributyl acetylcitrate is particularly preferable.
アセチルクエン酸トリアルキル(D)の配合量は、有機ポリイソシアネート化合物(A)100重量部に対して5〜500重量部が好ましく、より好ましくは10〜100重量部の範囲内で設定される。5部よりも少ない場合には有機ポリイソシアネート化合物(A)及び水との相溶化効果が得られにくい傾向にあり、500部よりも多い場合にはウレタン樹脂成分の割合が少なくなり、硬化物強度が低くなるために耐久性が低下する傾向にある。 The blending amount of the trialkyl acetyl citrate (D) is preferably 5 to 500 parts by weight, more preferably 10 to 100 parts by weight with respect to 100 parts by weight of the organic polyisocyanate compound (A). When the amount is less than 5 parts, the effect of compatibilization with the organic polyisocyanate compound (A) and water tends to be difficult to obtain. When the amount is more than 500 parts, the proportion of the urethane resin component decreases, and the cured product strength is reduced. However, the durability tends to decrease due to the decrease in the thickness.

希釈剤は、本発明の止水材を注入に適した粘度にするために用いられ、その例としてはジブチルフタレート、ジオクチルフタレート、ジイソノニルフタレートなどのフタル酸エステル、ジブチルアジペート、ジオクチルアジペート、ジイソノニルアジペート、ビス(2−(2−ブトキシエトキシ)エチル)アジペートなどのアジピン酸エステル、トリ(2−エチルヘキシル)トリメリテートなどのトリメリット酸エステルが挙げられる。これらのうち、環境への影響が少なく、安全性に優れることから、ビス(2−(2−ブトキシエトキシ)エチル)アジペート、トリ(2−エチルヘキシル)トリメリテートが好ましい。 Diluents are used to bring the water-stopping material of the present invention to a viscosity suitable for injection, examples of which include phthalate esters such as dibutyl phthalate, dioctyl phthalate, diisononyl phthalate, dibutyl adipate, dioctyl adipate, diisononyl adipate, Examples thereof include adipic acid esters such as bis (2- (2-butoxyethoxy) ethyl) adipate and trimellitic acid esters such as tri (2-ethylhexyl) trimellitate. Among these, bis (2- (2-butoxyethoxy) ethyl) adipate and tri (2-ethylhexyl) trimellitate are preferable because they have little influence on the environment and are excellent in safety.

The water-stopping material of the present invention described above is injected into the joint. Such injection can be performed by applying pressure as necessary, and using a known pump or the like. The injected water-stopping material reacts and hardens with water in the structure to stop the structure. In addition, when constructing for the purpose of preventing water leakage, it is also assumed that the target cracks and joints are dry. As a result, the water-stopping material is sufficiently cured and a desired effect is obtained.
