本発明は、下水処理の工程で排出される汚泥を焼却した焼却灰を有効に利用した断面修復材に関する。 The present invention relates to a cross-section repair material that effectively uses incinerated ash obtained by incinerating sludge discharged in a sewage treatment process.
硫化水素などの酸性物質に晒され、表面が劣化したコンクリート構造物の修復として、コンクリート面の劣化した部分を除去し、除去した跡を断面修復材で修復するといったことが行われている。断面修復材としては一般に耐酸コンクリートモルタルが使用されている。また、耐酸コンクリートモルタルに代わるものとして、耐酸性の樹脂、例えばエポキシ樹脂を結合材とし、これにフィラーとしての充填材を混ぜた耐酸樹脂モルタルがある。 In order to repair a concrete structure that has been exposed to an acidic substance such as hydrogen sulfide and the surface has deteriorated, the deteriorated portion of the concrete surface is removed, and the removed trace is repaired with a cross-sectional repair material. In general, acid-resistant concrete mortar is used as a cross-sectional restoration material. As an alternative to acid-resistant concrete mortar, there is acid-resistant resin mortar in which an acid-resistant resin, for example, an epoxy resin is used as a binder and a filler as a filler is mixed therewith.
近年、下水処理の工程で排出される汚泥を焼却した焼却灰（以下、単に焼却灰という。）を有効に利用する研究が盛んに行われており、その１つに、焼却灰を耐食性樹脂成分に充填材として添加した防食ライニング材が提案されている（例えば、特許文献１参照）。
特許文献１に記載された防食ライニング材は、エポキシ樹脂と硬化剤を混合した耐食性樹脂成分に充填材として焼却灰が、耐食性樹脂成分と焼却灰との混合重量比が４：６〜７：３の範囲で添加されている。
In recent years, research has been actively conducted to effectively use incineration ash (hereinafter simply referred to as incineration ash) incinerated sludge discharged in the sewage treatment process, and one of them is the use of incineration ash as a corrosion-resistant resin component.

The anticorrosion lining material described in Patent Document 1 has an incineration ash as a filler in an anticorrosion resin component in which an epoxy resin and a curing agent are mixed, and a mixing weight ratio of the anticorrosion resin component and the incineration ash is 4: 6 to 7: 3. It is added in the range.
特許文献１に記載された焼却灰を耐食性樹脂成分に充填材として添加した防食ライニング材は、エポキシ樹脂と硬化剤を混合した耐食性樹脂成分に充填材として焼却灰が、耐食性樹脂成分と焼却灰との混合重量比が４：６〜７：３の範囲で添加されたものとなっている。

以下、本発明に係る断面修復材を実施するための形態を詳細に説明する。
本発明に係る断面修復材は、エポキシ樹脂（ビスフェノールＡ型）に充填材を添加した主剤と、主剤に混合する硬化剤とからなり、エポキシ樹脂に添加する充填材の一部として下水汚泥の焼却灰を添加し、また、硬化剤にも充填材の一部として下水汚泥の焼却灰を添加している。
Hereinafter, the form for implementing the cross-section repair material which concerns on this invention is demonstrated in detail.
The cross-section repair material according to the present invention comprises a main agent obtained by adding a filler to an epoxy resin (bisphenol A type) and a curing agent mixed with the main agent, and incineration of sewage sludge as a part of the filler added to the epoxy resin. Ash is added, and sewage sludge incineration ash is also added to the curing agent as part of the filler.
先ず、主剤について詳細に説明する。エポキシ樹脂は主剤中３０〜４０重量％の範囲で混合される。本例では、エポキシ樹脂として、優れた耐薬品性を有するビスフェノールＡ型を使用している。
このエポキシ樹脂に添加される焼却灰は、下水処理の工程で排出される汚泥を脱水焼却し、粉砕機で粉砕して、最大粒径１００ミクロン以下、平均粒径１０〜３０ミクロンに粒度調整したものが使用される。この焼却灰を充填材の一部としてエポキシ樹脂に主剤中１０〜３０重量％の範囲で添加する。
断面修復材は、少なくとも２０ｍｍ以上の厚塗りが求められるため、充填材の一部として、軽量フィラーとして後述するマイクロバルーンが主剤中１３〜３０重量％の範囲で混合されることから、焼却灰が主剤中３０重量％を超えるとエポキシ樹脂との混合性が悪くなり、材料分離といった事態が生じる。焼却灰が主剤中１０重量％未満であると、焼却灰の使用量が少なく、満足できる省資源化が図れない。
First, the main agent will be described in detail. The epoxy resin is mixed in the range of 30 to 40% by weight in the main agent. In this example, a bisphenol A type having excellent chemical resistance is used as the epoxy resin.
The incineration ash added to this epoxy resin was dewatered and incinerated for sludge discharged in the sewage treatment process and pulverized with a pulverizer to adjust the particle size to a maximum particle size of 100 microns or less and an average particle size of 10 to 30 microns. Things are used. This incinerated ash is added to the epoxy resin as a part of the filler in the range of 10 to 30% by weight in the main agent.
Since the cross-section repair material is required to have a thick coating of at least 20 mm or more, the microballoon described later as a lightweight filler is mixed as a part of the filler in a range of 13 to 30% by weight in the main agent. When it exceeds 30% by weight in the main agent, the mixing property with the epoxy resin is deteriorated, and the material is separated. If the incinerated ash is less than 10% by weight in the main agent, the amount of incinerated ash used is small and satisfactory resource saving cannot be achieved.
本発明では、他の充填材として、塗布性を良くするヒュームドシリカを主剤中０〜２重量％の範囲で、耐薬品性に優れ施工性のよいタルクを主剤中２〜２０重量％の範囲で、軽量フィラーとしてマイクロバルーンを主剤中１３〜３０重量％の範囲で、塗布性を良くするシリカサンドを主剤中６．５〜１０重量％の範囲で、亀裂抵抗と引張強度の改善として化学・金属繊維の１種または２種以上の繊維を主剤中０．５〜２重量％の範囲で添加している。
化学繊維としては、アラミド繊維、ポリエステル系繊維、アクリル系繊維、ポリビニルアルコール系繊維等の合成繊維（ビニロン繊維）、ガラス繊維、炭素繊維等の無機繊維があり、本例ではビニロン繊維が使用されている。
In the present invention, as another filler, fumed silica that improves coatability is in the range of 0 to 2% by weight in the main agent, and talc having excellent chemical resistance and good workability is in the range of 2 to 20% by weight in the main agent. In order to improve crack resistance and tensile strength, microballoons in the range of 13 to 30% by weight in the main agent and silica sand to improve coatability in the range of 6.5 to 10% by weight in the main agent are used as lightweight fillers. One or more kinds of metal fibers are added in the range of 0.5 to 2% by weight in the main agent.
Chemical fibers include synthetic fibers (vinylon fibers) such as aramid fibers, polyester fibers, acrylic fibers, and polyvinyl alcohol fibers, and inorganic fibers such as glass fibers and carbon fibers. In this example, vinylon fibers are used. Yes.
また、エポキシ樹脂に反応性希釈剤を主剤中１〜３重量％の範囲で添加している。反応性希釈剤はエポキシ樹脂を低粘度化させることにより作業性を良くし、耐薬品性に優れている。
反応性希釈剤が主剤中１重量％未満であると耐薬品性が低下し、エポキシ樹脂の低粘度が不十分となって作業性が悪くなり、また、３重量％を超えると指蝕乾燥時間が延びてしまうので好ましくない。
反応性希釈剤としては、耐薬品性に優れるといった点で、クレジルグリシジルエーテルが好ましい。
Moreover, the reactive diluent is added to the epoxy resin in the range of 1 to 3% by weight in the main agent. The reactive diluent improves workability by reducing the viscosity of the epoxy resin, and is excellent in chemical resistance.
When the reactive diluent is less than 1% by weight in the main agent, the chemical resistance is lowered, the low viscosity of the epoxy resin is insufficient, and the workability is deteriorated. Is undesirably extended.
As the reactive diluent, cresyl glycidyl ether is preferable in terms of excellent chemical resistance.
次ぎに、硬化剤について詳細に説明する。アミン樹脂は硬化剤中３０〜３７重量％の範囲で混合される。本例では、アミン樹脂は、変性脂環式ポリアミンと変性脂肪族ポリアミンを混合したものからなり、硬化剤中変性脂環式ポリアミンが１９〜２４重量％、変性脂肪族ポリアミンが１１〜１３重量％の範囲で混合される。
本例のアミン樹脂の選定にあっては、湿潤環境下での作業を前提とし、耐薬品性、指蝕乾燥時間の性能、接着性、未反応遊離アミンが水と反応して表層が白くなる現象「アミンブラッシング」を考慮して選定した。試験結果により、変性脂環式ポリアミンは、優れた耐薬品性、接着性、耐アミンブラッシング性を示したが指蝕乾燥時間が長く、変性脂肪族ポリアミンは、優れた耐薬品性と指蝕乾燥時間の性能を示したが、耐アミンブラッシング性に劣ることがわかった。この試験結果を受け、変性脂環式ポリアミンと変性脂肪族ポリアミンを配合する検討を行い、試験の結果、選定目標を満足させるアミン樹脂として変性脂環式ポリアミンと変性脂肪族ポリアミンを選定し、その配合量を決定した。
Next, the curing agent will be described in detail. The amine resin is mixed in the curing agent in the range of 30 to 37% by weight. In this example, the amine resin is composed of a mixture of a modified alicyclic polyamine and a modified aliphatic polyamine, and the modified alicyclic polyamine in the curing agent is 19 to 24% by weight, and the modified aliphatic polyamine is 11 to 13% by weight. In the range of
In the selection of the amine resin of this example, assuming the work in a wet environment, the chemical layer, the performance of the dryness time, adhesion, unreacted free amine reacts with water and the surface layer becomes white Selected in consideration of the phenomenon “amine brushing”. According to the test results, the modified alicyclic polyamine showed excellent chemical resistance, adhesion, and amine brushing resistance, but the dry time of finger pitting was long, and the modified aliphatic polyamine had excellent chemical resistance and dryness. Although time performance was shown, it was found to be inferior in amine brushing resistance. Based on this test result, we conducted a study to mix modified alicyclic polyamine and modified aliphatic polyamine. The blending amount was determined.
アミン樹脂に添加される焼却灰は、主剤のエポキシ樹脂に添加される焼却灰と同様に、下水処理の工程で排出される汚泥を脱水焼却し、粉砕機で粉砕して、最大粒径１００ミクロン以下、平均粒径１０〜３０ミクロンに粒度調整したものが使用される。この焼却灰を充填材の一部としてアミン樹脂に硬化剤中１０〜３０重量％の範囲で添加する。
断面修復材は、少なくとも２０ｍｍ以上の厚塗りが求められるため、充填材の一部として、軽量フィラーとして後述するマイクロバルーンが硬化剤中１５〜３０重量％の範囲で混合されることから、焼却灰が硬化剤中３０重量％を超えるとアミン樹脂との混合性が悪くなり、材料分離といった事態が生じる。焼却灰が硬化剤中１０重量％未満であると、焼却灰の使用量が少なく、満足できる省資源化が図れない。
また、前記した焼却灰が主剤中３０重量％を超え且つ 焼却灰が硬化剤中３０重量％を超えると、焼却灰は比重が大きいので、断面修復材として求められる厚さに厚塗りしたとき、焼却灰の重さにより塗布層が崩壊してしまう。焼却灰が主剤中１０重量％未満で、且つ硬化剤中１０重量％未満であると、焼却灰の使用量が少なく、満足できる省資源化が図れない。
The incineration ash added to the amine resin is the same as the incineration ash added to the epoxy resin as the main agent. In the following, those having an average particle size adjusted to 10 to 30 microns are used. This incinerated ash is added to the amine resin as a part of the filler in the range of 10 to 30% by weight in the curing agent.
Since the cross-section repair material is required to have a thick coating of at least 20 mm or more, as a part of the filler, a microballoon described later as a lightweight filler is mixed in a range of 15 to 30% by weight in the curing agent. However, if it exceeds 30% by weight in the curing agent, the miscibility with the amine resin is deteriorated, resulting in a situation of material separation. If the incineration ash is less than 10% by weight in the curing agent, the amount of incineration ash used is small and satisfactory resource saving cannot be achieved.
Also, when the incineration ash exceeds 30% by weight in the main agent and the incineration ash exceeds 30% by weight in the curing agent, the incineration ash has a large specific gravity. The coating layer collapses due to the weight of the incinerated ash. If the incinerated ash is less than 10% by weight in the main agent and less than 10% by weight in the curing agent, the amount of incinerated ash used is small and satisfactory resource saving cannot be achieved.
本発明では、他の充填材として、塗布性を良くするヒュームドシリカを主剤中０〜２重量％の範囲で、耐薬品性に優れ施工性のよいタルクを主剤中３〜２０重量％の範囲で、軽量フィラーとしてマイクロバルーンを主剤中１５〜３０重量％の範囲で、塗布性を良くするシリカサンドを主剤中６．５〜１０重量％の範囲で、亀裂抵抗と引張強度の改善としてビニロン繊維を主剤中０〜１重量％の範囲で、さらに、湿潤面コンクリートや他の基盤への付着を改善するものとしてシランカップリング剤を硬化剤中０．５〜２重量％の範囲で添加している。 In the present invention, fumed silica that improves coatability as the other filler is in the range of 0 to 2% by weight in the main agent, and talc having excellent chemical resistance and good workability is in the range of 3 to 20% by weight in the main agent. As a lightweight filler, the microballoon is in the range of 15 to 30% by weight in the main agent, and the silica sand for improving the coating property is in the range of 6.5 to 10% by weight in the main agent, and the vinylon fiber is used to improve crack resistance and tensile strength. Is added in a range of 0 to 1% by weight in the main agent, and a silane coupling agent is added in a range of 0.5 to 2% by weight in the curing agent to improve adhesion to wet surface concrete and other substrates. Yes.
本例では、前記主剤と前記硬化剤を、前記主剤と前記硬化剤の混合重量比が１００：４５〜１００：５５の範囲で混合し、断面修復材を得る。主剤１００に対し硬化剤が４５未満であると未硬化部分が発生し、また、主剤１００に対し前記硬化剤が５５を超えると硬化剤が残り、残った硬化剤が白化するといった白化現象が発生する。 In this example, the main agent and the curing agent are mixed in a range of a mixing weight ratio of the main agent and the curing agent of 100: 45 to 100: 55 to obtain a cross-sectional repair material. When the curing agent is less than 45 with respect to the main agent 100, an uncured portion is generated, and when the curing agent exceeds 55 with respect to the main agent 100, the curing agent remains, and the remaining curing agent is whitened. To do.
本発明の断面修復材によれば、エポキシ樹脂に添加する充填材の一部として下水汚泥の焼却灰を添加し、また、アミン樹脂にも充填材の一部として下水汚泥の焼却灰を添加したので、エポキシ樹脂、アミン樹脂のいずれか一方にのみ添加するよりも大量に添加することが可能になり、省資源化が図れる。
そして、前記エポキシ樹脂に添加した焼却灰を主剤中１０〜３０重量％の範囲とし、また、アミン樹脂に添加した焼却灰を硬化剤中１０〜３０重量％の範囲としたので、塗布層にダレが無く、断面修復材に要求される厚塗りができる。
According to the cross-sectional repair material of the present invention, incineration ash of sewage sludge is added as part of the filler added to the epoxy resin, and incineration ash of sewage sludge is also added to the amine resin as part of the filler. Therefore, it can be added in a larger amount than when added only to one of the epoxy resin and the amine resin, and resource saving can be achieved.
The incineration ash added to the epoxy resin is in the range of 10 to 30% by weight in the main agent, and the incineration ash added to the amine resin is in the range of 10 to 30% by weight in the curing agent. No thickening required for cross-section repair materials.
また、本例では、エポキシ樹脂に反応性希釈剤を主剤中１〜３重量％の範囲で添加したので、エポキシ樹脂の低粘度化が図れるのでコテ離れが良く作業性に優れ、また、耐薬品性、指蝕乾燥時間に優れたものとなる。
また、本例では、アミン樹脂は、変性脂環式ポリアミンと変性脂肪族ポリアミンを混合したものであるので、変性脂環式ポリアミンの耐水性によりエポキシ樹脂特有の未反応遊離アミンが水と反応して表層が白くなる現象「アミンブラッシング」を回避することができるとともに、養生段階における湿気存在下における優れた接着性を発揮するので、湿度の高い下水環境下での作業を可能にし、また、変性脂肪族ポリアミンにより指蝕乾燥時間の短縮化を図ることができる。
また、本例では、エポキシ樹脂およびアミン樹脂には、それぞれ充填材として焼却灰の他にエポキシ樹脂およびアミン樹脂には、それぞれ充填材として焼却灰の他にフュームドシリカ、タルク、マイクロバルーン、ビニロン繊維、シリカサンドが添加されているので、厚塗りが可能となり、また、塗布層に強い圧縮性、靱性が得られ、さらに、耐薬品性、施工性、ダレ性に一層優れたものとなる。
また、本例では、主剤と硬化剤を、主剤と硬化剤の混合重量比が１００：４５〜１００：５５の範囲で混合するので、未硬化部分や硬化剤が残り白化する白化現象の無い塗布層を得ることができる。
Moreover, in this example, the reactive diluent was added to the epoxy resin in the range of 1 to 3% by weight in the main agent, so that the viscosity of the epoxy resin can be reduced, so that the iron separation is good and the workability is excellent. It is excellent in the property and the dry time for finger pitting.
In this example, since the amine resin is a mixture of a modified alicyclic polyamine and a modified aliphatic polyamine, the unreacted free amine unique to the epoxy resin reacts with water due to the water resistance of the modified alicyclic polyamine. In addition to avoiding the phenomenon of whitening of the surface layer, “amine brushing”, and exhibiting excellent adhesiveness in the presence of moisture at the curing stage, it is possible to work in a sewage environment with high humidity, and denatured The aliphatic polyamine can shorten the time for dryness of finger erosion.
In addition, in this example, in addition to incinerated ash as a filler for epoxy resin and amine resin, in addition to incinerated ash as a filler, fumed silica, talc, microballoon, vinylon, respectively. Since fibers and silica sand are added, thick coating is possible, strong compressibility and toughness are obtained in the coating layer, and chemical resistance, workability, and sagging properties are further improved.
Further, in this example, the main agent and the curing agent are mixed in a mixing weight ratio of the main agent and the curing agent in the range of 100: 45 to 100: 55, so that there is no whitening phenomenon in which uncured portions and the curing agent remain and whiten. A layer can be obtained.
