Description
本発明は、透明板の補修方法に関し、詳しくは、高速道路の遮音壁などに利用される透明板の補修方法に関する。 The present invention relates to a method for repairing a transparent plate, and more particularly to a method for repairing a transparent plate used for a sound insulation wall of an expressway.
高速道路の両側には、近隣への騒音の問題を軽減するために遮音壁を設けるのが一般的である。
このとき、高速道路上を走行する車両の運転者が景観を楽しむことができるように、遮音壁を透明板で形成することがあった。
しかし、透明板を用いた遮音壁の場合、太陽光や排気ガスなどに曝される厳しい条件下での使用となるため、透明板表面が劣化して透明性が低下してしまう問題があった。
これを避けるために、例えば、フッ素樹脂とシリケート化合物と、硬化剤としてブロックポリイソシアネートまたはフリーのポリイソシアネートを含有する塗料組成物から得られた低汚染性塗膜が形成されている透明板が知られている（特許文献１参照。）。
It is common to provide sound insulation walls on both sides of the highway in order to reduce the problem of noise in the vicinity.
At this time, the sound insulation wall may be formed of a transparent plate so that the driver of the vehicle traveling on the highway can enjoy the scenery.
However, in the case of a sound insulating wall using a transparent plate, since it is used under severe conditions exposed to sunlight, exhaust gas, etc., there is a problem that the transparency of the transparent plate is deteriorated.
In order to avoid this, for example, a transparent plate on which a low-fouling coating film obtained from a coating composition containing a fluororesin, a silicate compound, and a block polyisocyanate or a free polyisocyanate as a curing agent is formed is known. (See Patent Document 1).
しかし、上記従来技術は、低汚染性塗膜が形成された透明板を新規に提案するものであって、既存の劣化した透明板を補修する方法を提案するものではない。透明板は、既に、高速道路の遮音壁その他の用途において広く使用されており、これら既設の透明板を前記のごとき新規な透明板に設置しなおすのは、費用、労力ともに多大な負担を招く。
このような理由から、単に劣化し難い透明板ではなく、既に劣化した既設の透明板を補修して透明性を復元する補修方法が求められる。そして、補修後に再び劣化が起こるのでは、補修の意味が損なわれるので、補修後の透明板は劣化が起こり難いことが望まれる。
なお、本発明者が検討したところによると、劣化した透明板は、通常の洗浄処理、例えば、表面を水で洗い流したり脱脂処理したりするだけでは、透明性を復元し、かつ、長期にわたってこれを維持するということはできなかった。
また、上記従来技術の低汚染性塗膜は、フッ素樹脂を主要成分とするものが殆どであり、技術の豊富化の観点から、異なる成分組成のものも検討されるべきである。
However, the above prior art proposes a new transparent plate on which a low-contamination coating film is formed, and does not propose a method for repairing an existing deteriorated transparent plate. Transparent plates have already been widely used in sound insulation walls and other applications on expressways, and it is very expensive and labor intensive to re-install these existing transparent plates on new transparent plates as described above.
For these reasons, there is a need for a repair method that restores transparency by repairing an existing transparent plate that has already deteriorated, rather than a transparent plate that is not easily deteriorated. If the deterioration occurs again after the repair, the meaning of the repair is lost. Therefore, it is desired that the transparent plate after the repair is hardly deteriorated.
In addition, according to a study by the present inventor, a deteriorated transparent plate can be restored to its transparency over a long period of time by simply washing it with water or degreasing the surface. It was not possible to maintain.
Moreover, most of the above-mentioned conventional low-contamination coating films are mainly composed of a fluororesin, and those having different component compositions should also be considered from the viewpoint of enrichment of technology.
そこで、本発明は、フッ素系以外の塗膜形成により、既存の劣化した透明板の透明性を復元し、補修後も長く劣化を抑えることのできる透明板の補修方法を提供することを目的としている。 Then, this invention aims at providing the repair method of the transparent plate which can restore | restore the transparency of the existing deteriorated transparent board by film formation other than a fluorine-type, and can suppress deterioration for a long time after repair. Yes.
本発明者は、上記課題を解決するために、鋭意検討を行い、透明板上にアルキルアルコキシシランを含有する下地処理剤を塗工する下地処理工程と、前記下地処理工程で下地処理がなされた下地処理済み透明板上にストレートシリコーンを含有する表面処理剤を塗工する表面処理工程とを含むこととすれば、下地処理剤が透明板表面の微細な凹凸を埋めるためか、磨耗傷などの表面欠陥が解消されて透明性が復元するとともに、下地処理剤が透明板と表面処理剤との密着性を高める上、表面処理剤が太陽光や排気ガスによる透明板の劣化を長期にわたり抑制できることを見出した。
本発明は、上記知見に基づき完成されるに至った。
In order to solve the above-mentioned problems, the present inventor conducted intensive studies and applied a ground treatment agent containing an alkylalkoxysilane on a transparent plate, and the ground treatment was performed in the ground treatment step. If the surface treatment process includes applying a surface treatment agent containing straight silicone on the transparent plate that has been subjected to the ground treatment, the ground treatment agent may fill fine irregularities on the surface of the transparent plate, Transparency is restored by eliminating surface defects, and the surface treatment agent improves adhesion between the transparent plate and the surface treatment agent, and the surface treatment agent can suppress deterioration of the transparent plate due to sunlight or exhaust gas over a long period of time. I found.
The present invention has been completed based on the above findings.
すなわち、本発明にかかる透明板の補修方法は、透明板上にアルキルアルコキシシランを含有する下地処理剤を塗工する下地処理工程と、前記下地処理工程で下地処理がなされた下地処理済み透明板上にストレートシリコーンを含有する表面処理剤を塗工する表面処理工程とを含むことを特徴とする。 That is, the method for repairing a transparent plate according to the present invention includes a ground treatment step of applying a ground treatment agent containing an alkylalkoxysilane on a transparent plate, and a ground-treated transparent plate subjected to the ground treatment in the ground treatment step. And a surface treatment step of applying a surface treatment agent containing straight silicone.
本発明によれば、劣化した透明板の透明性を復元できるとともに、補修後も長期にわたって劣化を抑制することができる。 According to the present invention, the transparency of a deteriorated transparent plate can be restored, and deterioration can be suppressed over a long period after repair.
以下、本発明にかかる透明板の補修方法の好ましい実施形態について詳しく説明するが、本発明の範囲はこれらの説明に拘束されることはなく、以下の例示以外についても、本発明の趣旨を損なわない範囲で適宜変更実施し得る。 Hereinafter, preferred embodiments of the method for repairing a transparent plate according to the present invention will be described in detail.

In addition to these treatment steps, other steps may also be included, especially for the purpose of removing dirt such as oil adhering to the transparent plate surface before the substrate treatment step. It is preferable to include a cleaning step for cleaning the plate.
洗浄工程は、従来公知の方法で行うことができ、例えば、水を用いて透明板表面の汚れを洗い流したり、スポンジなどで透明板表面を擦ったりする方法が挙げられる。その際、透明板表面の油脂を分解するなどの目的で、洗剤を併用しても良い。
洗浄工程として、例えば、溶媒を含有させたウエスなどで透明板表面を拭くなどの脱脂処理を採用しても良い。脱脂処理で使用される溶媒としては、例えば、イソプロピルアルコール、エタノール、メタノールなどのアルコール系溶媒、ヘキサン、ヘプタン、オクタンなどの炭化水素系溶媒、ジブチルエーテル、エチレングリコール、モノブチルエーテルなどのエーテル系溶剤、酢酸エチル、酢酸ブチルなどのエステル系溶剤などが挙げられる。
なお、透明板表面を傷付けると透明性に影響する可能性があるので、洗浄工程の際に透明板表面を擦る場合は、なるべく傷付けないように加減するのが良い。
The washing step can be performed by a conventionally known method, for example, a method of washing away the dirt on the surface of the transparent plate using water or rubbing the surface of the transparent plate with a sponge or the like. At that time, a detergent may be used in combination for the purpose of decomposing the oil on the surface of the transparent plate.
As the cleaning step, for example, a degreasing treatment such as wiping the surface of the transparent plate with a waste containing a solvent may be employed. Examples of the solvent used in the degreasing treatment include alcohol solvents such as isopropyl alcohol, ethanol, and methanol, hydrocarbon solvents such as hexane, heptane, and octane, ether solvents such as dibutyl ether, ethylene glycol, and monobutyl ether, Examples thereof include ester solvents such as ethyl acetate and butyl acetate.
In addition, since the transparency may be affected if the surface of the transparent plate is damaged, when rubbing the surface of the transparent plate during the cleaning process, it is preferable to adjust the surface so as not to damage as much as possible.
次に、下地処理工程及び表面処理工程について説明する。
下地処理工程及び表面処理工程では、それぞれ、上述した下地処理剤及び表面処理剤を塗工する。これらの塗工は、従来公知の方法で行えばよく、例えば、刷毛塗りなどが挙げられる他、スポンジに染み込ませて塗工するといった方法も採用できる。表面形状の粗さが目立つ透明板の補修においては、特に下地処理剤の塗工の際に、これを染み込ませたスポンジを用いて、摺り込むように塗工するのが好ましい。
表面処理工程では、下地処理工程により下地処理された下地処理済み透明板上にストレートシリコーンを含有する表面処理剤を塗工するが、このとき、通常は、下地処理工程で形成された塗膜が、少なくとも表面処理剤と混ざり合わない程度に乾燥してから表面処理剤の塗工を行う。
例えば、下地処理剤を塗工した後、５〜１５分程度自然乾燥した後に、表面処理剤を塗工する。
また、表面処理剤を塗工した後は、例えば、１２〜３６時間程度自然乾燥する。
Next, the ground treatment process and the surface treatment process will be described.
In the ground treatment step and the surface treatment step, the above-described ground treatment agent and surface treatment agent are applied, respectively. These coatings may be performed by a conventionally known method. For example, brush coating or the like may be used, and a method of soaking in a sponge may be employed. In repairing a transparent plate with a noticeable surface roughness, it is preferable to apply the surface treatment agent so as to be rubbed with a sponge soaked with the surface treatment agent.
In the surface treatment process, a surface treatment agent containing straight silicone is applied onto the ground-treated transparent plate that has been ground-treated in the ground-treatment process. In this case, the coating film formed in the ground-treatment process is usually used. Then, the surface treatment agent is applied after drying to such an extent that it does not mix with the surface treatment agent.
For example, after applying the surface treatment agent, the surface treatment agent is applied after naturally drying for about 5 to 15 minutes.
Moreover, after coating the surface treating agent, it is naturally dried for about 12 to 36 hours, for example.
以下、本発明にかかる透明板の補修方法について実施例を示すが、本発明はこれら実施例に限定されるものではない。 Hereinafter, although an example is shown about a repairing method of a transparent board concerning the present invention, the present invention is not limited to these examples.

測定は、スガ試験機社製の「ＨＺ−２」を用いて、ＪＩＳ Ｋ７１０５に準じて行った。結果を下表に示す。
[Evaluation Test 2]
<Optical characteristics test>
Optical characteristics tests were performed on the transparent plates of Example 2 (Examples 2-1 and 2-2) and Comparative Example 2 (Comparative Examples 2-1 and 2-2).
The measurement was performed according to JIS K7105 using “HZ-2” manufactured by Suga Test Instruments Co., Ltd. The results are shown in the table below.
測定は、試料の３点について行い、平均値も併記した。
上記において、平行光線透過率は、物質をまっすぐ通る光の透過率であり、この数値が高いほど、光が透過して見えやすいということを意味する。
ヘーズは、曇り度を意味し、（拡散光線透過率／全光線透過率）×１００で表される。この数値が高いほど、曇っている度合いが大きく見えにくいということを意味する。
拡散光線透過率は、物体の表面や内部で拡散を生じて射出する透過光、すなわち、まっすぐにではなく屈折して透過した光の量を測定したものである。
全光線透過率は、拡散光線透過率と平行光線透過率の和である。
Measurement was performed on three points of the sample, and the average value was also shown.
In the above, the parallel light transmittance is the transmittance of light that passes straight through the substance, and the higher this value, the easier the light is transmitted and visible.
Haze means haze and is represented by (diffuse light transmittance / total light transmittance) × 100. A higher value means that the degree of cloudiness is more difficult to see.
The diffuse light transmittance is a measure of the amount of transmitted light that diffuses and exits the surface or inside of an object, that is, the amount of light that is refracted and transmitted instead of being straight.
The total light transmittance is the sum of the diffuse light transmittance and the parallel light transmittance.
＜考察＞
表２の結果を見ると、実施例２−１、実施例２−２のいずれにおいても、クリアスカイ工法を適用する前の比較例２−１、比較例２−２と比べたとき、全光線透過率が僅かに向上しているとともに、その内訳を見ると、平行光線透過率が格段に向上し、他方で拡散光線透過率が大幅に低下していることが分かる。すなわち、透過光のうち、透明板で拡散する光の量が減少し、まっすぐ透過する光の量が大幅に増大していることが分かる。
また、ヘーズも、クリアスカイ工法により格段に低下していることが分かる。
以上の結果から、本発明の補修方法によって、透明板の透明性が復元できることが分かる。
<Discussion>
When the result of Table 2 is seen, in any of Example 2-1 and Example 2-2, when compared with Comparative Example 2-1 and Comparative Example 2-2 before applying the clear sky method, the total light beam While the transmittance is slightly improved, and a breakdown thereof, it can be seen that the parallel light transmittance is remarkably improved while the diffuse light transmittance is greatly reduced. That is, it can be seen that the amount of light diffused by the transparent plate in the transmitted light is decreased, and the amount of light transmitted straight is greatly increased.
In addition, it can be seen that haze is also significantly reduced by the clear sky method.
From the above results, it can be seen that the transparency of the transparent plate can be restored by the repair method of the present invention.
本発明にかかる透明板の補修方法は、例えば、高速道路の遮音壁として用いられる透明板の補修に好適に利用することができる。 The method for repairing a transparent plate according to the present invention can be suitably used for repairing a transparent plate used as a sound insulation wall of an expressway, for example.
