Description

本発明は、たとえば原子力発電所あるいは放射線管理区域内に適用することが好適である、防塵性および滑り止め性に優れた塗膜およびその塗膜を形成しうる塗料に関する。   The present invention relates to a coating film excellent in dustproof property and anti-slip property, and a coating material capable of forming the coating film, which is suitable for application in, for example, a nuclear power plant or a radiation control area.

原子力電力プラントなどの放射性物質を取り扱う施設の放射線管理区域内では、設備に対して、放射性物質を含む塵埃などが残留した場合にそれらを効率的に除去することができる性質、いわゆる除塵性が要求される。このため、作業用通路などの塗装では、平滑な表面形状を特徴とする塗膜を形成する塗料が用いられてきた。しかし、表面が平滑な塗膜は、除塵性は良好であるが、特に床面が濡れた場合などは滑りやすいなど、作業者や歩行者にとって転倒の危険性があった。また、塗膜の滑り止め性を確保するための市販の滑り止め塗料は、表面の凹凸が大きいため、除塵性に係る塵埃の除去性が悪く、放射線管理区域内の施設に対する使用に向かない。そこで、高い滑り止め性能と除塵性とを両立することのできる滑り止め塗料の開発が求められている。   In the radiation control area of facilities that handle radioactive materials such as nuclear power plants, when equipment containing dust, etc. containing radioactive material remains, it must be efficiently removed, so-called dust removal. Is done. For this reason, paints for forming a coating film characterized by a smooth surface shape have been used in the painting of work passages and the like. However, a coating film with a smooth surface has good dust removal properties, but there is a risk of falling for workers and pedestrians such as slipperiness especially when the floor surface is wet. In addition, commercially available anti-slip coatings for ensuring the anti-slip property of the coating film have large surface irregularities, so that the dust removal property related to dust removal is poor and is not suitable for use in facilities in radiation control areas. Therefore, development of an anti-slip coating material that can achieve both high anti-slip performance and dust removal performance is required.

従来の滑り止め塗料としては、たとえば、特許文献1において、水性樹脂(エポキシ系樹脂等)および滑り防止剤(アルミナ、珪砂、塩化ビニル樹脂ビーズ、ポリエチレンパウダー等)を含有する床面用水性塗料の発明が開示されている。そして、上記滑り防止剤の含有量を上記水性樹脂100重量部に対して12.5〜100重量部とすることにより十分な滑り防止効果を発揮することができる旨、また、上記滑り防止剤の平均粒径を床面に塗布されて乾燥した塗膜の平均膜厚の1.1〜3.5倍とすることにより、平面の滑りをより効果的に防止するとともに光沢があり外観がよい仕上がりの塗膜を形成できる旨が記載されている。しかし、塗膜の防塵性については、「これを床面に塗布することにより、ゴミ等の異物の付着を防止できる」との一般的な効果以上のことは記載されていない。
特開平10−067951号公報
As a conventional anti-slip paint, for example, in Patent Document 1, an aqueous paint for floor surface containing an aqueous resin (epoxy resin, etc.) and an anti-slip agent (alumina, silica sand, vinyl chloride resin beads, polyethylene powder, etc.) is used. The invention is disclosed. And it is possible to exhibit a sufficient anti-slip effect by adjusting the content of the anti-slip agent to 12.5 to 100 parts by weight with respect to 100 parts by weight of the aqueous resin, By making the average particle size 1.1 to 3.5 times the average film thickness of the coated film that has been applied to the floor and dried, the finish is more glossy and has a good appearance while preventing slippage of the plane more effectively. It is described that a coating film can be formed. However, the dust-proof property of the coating film is not described as being more than the general effect that “the application of this to the floor surface prevents the adhesion of foreign substances such as dust”.

These epoxy resins may be used individually by 1 type, and may be used in combination of 2 or more type as needed.

本発明で用いることのできるエポキシ樹脂用主剤(a)は一般的に販売されており、たとえば、ビスフェノール型エポキシ樹脂であれば、ジャパンエポキシレジン株式会社製「JER1001X75」などの商品が好適である。   The epoxy resin main agent (a) that can be used in the present invention is generally sold. For example, if it is a bisphenol type epoxy resin, a product such as “JER1001X75” manufactured by Japan Epoxy Resin Co., Ltd. is suitable.

なお、本発明における「エポキシ樹脂用主剤(a)」の重量、あるいは以下に述べる「エポキシ樹脂用硬化剤(b)」の重量は、これらの固形分のみの重量を指すものであり、これらの一般的な商品等に含まれている溶剤等の揮発性成分(塗膜中に残存しない成分)の重量は除外される。   The weight of the “epoxy resin main agent (a)” in the present invention or the weight of the “epoxy resin curing agent (b)” described below refers to the weight of these solids only. The weight of volatile components (components not remaining in the coating film) such as solvents contained in general products is excluded.

一方、エポキシ樹脂用硬化剤(b)としては、たとえば、ポリアミド、脂肪族ポリアミン、脂環式ポリアミン、芳香族ポリアミンなどのポリアミン系硬化剤、あるいはダイマー酸変性、エポキシド変性(エポキシアダクト)、マンニッヒ変性などによるポリアミン変性物が挙げられる。これらの硬化剤は、1種単独で用いてもよく、必要に応じて2種以上組み合わせて用いてもよい。   On the other hand, examples of the epoxy resin curing agent (b) include polyamine curing agents such as polyamide, aliphatic polyamine, alicyclic polyamine, and aromatic polyamine, dimer acid modification, epoxide modification (epoxy adduct), and Mannich modification.

本発明の滑り止め塗料における上記主剤(a)と硬化剤(b)の配合量(合計値)は、それぞれエポキシ当量、活性水素当量(アミン当量)などによっても変動しうるが、塗料の塗装作業性や得られる塗膜の付着性、強度等の性能を考慮すると、滑り止め塗料中の全固形分100重量部に対して、通常25〜70重量部、好ましくは30〜60重量部である。
The epoxy resin curing agent (b) that can be used in the present invention is generally sold. For example, a product such as “PA-53” manufactured by Akira Ohtake Shin Chemical Co., Ltd. is suitable.
The blending amount (total value) of the main agent (a) and the curing agent (b) in the anti-slip coating of the present invention may vary depending on the epoxy equivalent, active hydrogen equivalent (amine equivalent), etc. In view of properties such as property, adhesion of the resulting coating film, and strength, the amount is usually 25 to 70 parts by weight, preferably 30 to 60 parts by weight with respect to 100 parts by weight of the total solid content in the anti-slip coating.

樹脂粉末(c)
本発明で用いることのできる樹脂粉末(c)としては、たとえば、ポリプロピレン粉末、ポリエチレン粉末、ポリエステル粉末、ポリ塩化ビニル粉末、架橋アクリル粉末が挙げられる。これらの樹脂粉末は、1種単独で、または2種以上を組み合わせて用いることができる。なかでも、ポリプロピレンやポリエステル(ポリエチレンテレフタレート等)といった樹脂の粉末は、高温でも分解されにくく、110℃程度の高温環境にさらされる原子炉格納容器内などに塗膜を形成する上で適した素材である。なお、本発明による効果を妨げない範囲で、少量のその他の種類の樹脂粉末を併用することも可能であるが、本発明で用いる樹脂粉末(c)は、実質的に、ポリプロピレン粉末、ポリエチレン粉末、ポリエステル粉末、ポリ塩化ビニル粉末、架橋アクリル粉末のうちのいずれか一種以上のみからなることが望ましい。
Resin powder (c)
Examples of the resin powder (c) that can be used in the present invention include polypropylene powder, polyethylene powder, polyester powder, polyvinyl chloride powder, and crosslinked acrylic powder. These resin powders can be used alone or in combination of two or more. In particular, resin powders such as polypropylene and polyester (polyethylene terephthalate, etc.) are not easily decomposed even at high temperatures, and are suitable materials for forming a coating film in a reactor containment vessel exposed to a high temperature environment of about 110 ° C. is there. A small amount of other types of resin powder can be used in combination as long as the effects of the present invention are not hindered, but the resin powder (c) used in the present invention is substantially a polypropylene powder or a polyethylene powder. Desirably, the powder comprises at least one of polyester powder, polyvinyl chloride powder, and crosslinked acrylic powder.

また、樹脂粉末(c)の粉末粒は、本発明の滑り止め塗膜に所定の滑り止め性および除塵性を付与するために、大きさおよび形状について所定の基準を満たすことが望ましい。すなわち、本発明の樹脂粉末(c)としては、その80%以上の固体が、粉末粒の最大長さが20μm以上300μm以下、好ましくは30μm以上200μm以下であり、かつ粉末粒の任意の断面形状における最小長さに対する最大長さの比率(アスペクト比)が17倍以内、好ましくは10倍以内、より好ましくは5倍以内であるとの条件を満たすものが用いられる。粉末粒の最大長さが300μm以上ならば繊維付着性が不良(たとえば後述するような試験方法により判別する)であり、20μm以下ならば所定のすべり抵抗性が得られない。またアスペクト比が17倍を超えても繊維付着性などが不良になる。   In addition, it is desirable that the powder particles of the resin powder (c) satisfy predetermined standards for size and shape in order to impart predetermined anti-slip properties and dust removal properties to the anti-slip coating film of the present invention. That is, as the resin powder (c) of the present invention, 80% or more of the solid has a maximum particle size of 20 μm to 300 μm, preferably 30 μm to 200 μm, and an arbitrary cross-sectional shape of the powder particle The ratio of the maximum length to the minimum length (aspect ratio) is within 17 times, preferably within 10 times, more preferably within 5 times. If the maximum length of the powder grains is 300 μm or more, the fiber adhesion is poor (for example, determined by a test method as described later), and if it is 20 μm or less, the predetermined slip resistance cannot be obtained. Further, even when the aspect ratio exceeds 17 times, the fiber adhesion and the like are poor.

なお、粉末粒の最大長さおよびアスペクト比について、上述のような条件が満たされているかどうかは、樹脂粉末のサンプリングおよび顕微鏡観察することにより確認される。
本発明において、樹脂粉末(c)は、滑り止め塗料から形成される乾燥した塗膜中の樹脂粉末(c)の容量が、好ましくは2〜20%、より好ましくは4〜17%となる量で、滑り止め塗料中に含有される。乾燥した塗膜中の樹脂粉末(c)の容量が、2%以下であれば所定のすべり抵抗性が得られず、20%以上であれば繊維付着性などが不良となる。換言すれば、本発明の滑り止め塗料は、エポキシ樹脂用主剤(a)、エポキシ樹脂用硬化剤(b)その他必要に応じて含有される塗料中の全固形分に対して、上記範囲の容量の樹脂粉末(c)を含有するということである。このような配合量とすることにより、塗膜に優れた滑り止め性および除塵性を付与すること、すなわち、後述するような所定の油溜り深さ(Rvk)や、所定の拭き取り試験性能、吸い込み試験性能、繊維付着試験性能、および滑り抵抗値を具備する塗膜を形成することが可能となる。
Whether or not the above-described conditions are satisfied with respect to the maximum length and aspect ratio of the powder grains is confirmed by sampling the resin powder and observing with a microscope.
In the present invention, the resin powder (c) is such that the volume of the resin powder (c) in the dried coating film formed from the anti-slip coating is preferably 2 to 20%, more preferably 4 to 17%. And contained in the anti-slip paint. If the capacity of the resin powder (c) in the dried coating film is 2% or less, the predetermined slip resistance cannot be obtained, and if it is 20% or more, the fiber adhesion or the like becomes poor. In other words, the anti-slip paint of the present invention has a capacity in the above range with respect to the total solid content in the epoxy resin main agent (a), epoxy resin curing agent (b) and other paints contained as necessary. It is that the resin powder (c) of this is contained.

If necessary for viscosity adjustment in the painting operation, components such as a solvent may be further added to the coating composition produced as described above.
<Coating method and application of coating composition>
From the anti-slip paint of the present invention, a coating film having both excellent dust removal and anti-slip properties can be obtained. Therefore, it is particularly preferable to apply it to facilities (floor materials, equipment, etc.) used in nuclear power plants or radiation control areas where dust containing radioactive substances is required at a high level.

目的とする基材への滑り止め塗料の塗装は、エポキシ系塗料などについての一般的な塗装方法と同様にして行うことができる。たとえば、エアレススプレーまたはエアースプレーを用いたスプレー塗装や、ハケ塗り、ローラー塗りなどにより塗装することができる。   Application of the non-slip coating to the target substrate can be performed in the same manner as a general coating method for epoxy-based coatings. For example, it can be applied by spray coating using airless spray or air spray, brush coating, roller coating, or the like.

本発明において、滑り止め塗料は、その中に含有される全固形分が好ましくは50g/m2以上200g/m2以下、より好ましくは60g/m2以上130g/m2以下となる量で、対象とする基材に塗布される。このような量で滑り止め塗料を使用することにより、滑り止め性と除塵性とを兼ね備えた塗膜、より具体的には、油溜り深さ(Rvk)が1〜50μmである、あるいは、後述する所定の拭き取り試験性能、吸い込み試験性能および滑り抵抗値(BPN)を満たす塗膜を、基材表面に形成することが可能である。 In the present invention, the anti-slip coating is such that the total solid content contained therein is preferably 50 g / m 2 or more and 200 g / m 2 or less, more preferably 60 g / m 2 or more and 130 g / m 2 or less. It is applied to the target substrate. By using the non-slip paint in such an amount, the coating film having both anti-slip property and dust removal property, more specifically, the oil sump depth (Rvk) is 1 to 50 μm, or described later. It is possible to form a coating film satisfying predetermined wiping test performance, suction test performance, and slip resistance value (BPN) on the surface of the substrate.

なお、上記の量で滑り止め塗料を塗布することにより形成される乾燥塗膜の膜厚は、塗料中の配合組成によっても変動しうるが、およそ30〜120μmとなる。
< 塗膜の物性 >
本発明において、塗膜の除塵性および滑り止め性は、次に掲げる2通りの方法により表現することができる。
In addition, although the film thickness of the dry coating film formed by apply | coating a non-slip coating material with said quantity may be fluctuate | varied also with the compounding composition in a coating material, it will be about 30-120 micrometers.
<Physical properties of coating film>
In the present invention, the dust removal property and anti-slip property of the coating film can be expressed by the following two methods.

一つは、JIS B0601:1994の粗さ形状パラメータである油溜り深さ(Rvk)で表す方法である。Rvkが50μm以下、好ましくは20μm以下である塗膜は、平滑塗膜と同等の良好な除塵性を示す。また、Rvkが1μm以上、好ましくは4μm以上である塗膜は、平滑塗膜と比較して十分な滑り止め性の向上を示す。このようなRvkは、一般的な表面粗さ計を用いて測定することが可能である。   One is a method represented by oil sump depth (Rvk) which is a roughness shape parameter of JIS B0601: 1994. A coating film having an Rvk of 50 μm or less, preferably 20 μm or less, exhibits good dust removal performance equivalent to a smooth coating film. Moreover, the coating film whose Rvk is 1 μm or more, preferably 4 μm or more shows a sufficient improvement in anti-slip properties as compared with a smooth coating film. Such Rvk can be measured using a general surface roughness meter.

もう一つは、独自の「拭き取り試験」、「吸い込み試験」および「繊維付着試験」の成績による除塵性と、舗装路面について一般的な、振り子式スキッドレジスタンステスターを用いて測定した「滑り抵抗値」(BPN)による滑り止め性で表す方法である。上記「拭き取り試験」、「吸い込み試験」および「繊維付着試験」の態様は、後述する実施例の記載において具体的に示す。   The other is dust resistance based on the results of the original “wiping test”, “suction test” and “fiber adhesion test”, and “slip resistance value” measured using a pendulum skid resistance tester, which is commonly used for pavement surfaces. ”(BPN). The aspects of the “wiping test”, “suction test”, and “fiber adhesion test” will be specifically shown in the description of Examples described later.

本発明者が放射線管理区域内の実設備での塵埃を調査した結果、塵埃の内容は、衣類に由来すると思われる繊維状のものが一部であり、大部分は直径数十μm程度の塊状のものであることが判明した。そして、塊状の塵埃には、潮解性を示す水溶性のものと、非水溶性のものとが存在した。したがって、実設備における放射性物質を含む塵埃の除去性については、濡れた状態での拭き取り性と、掃除機などによる吸引除去性とを評価する必要が
あるとの知見を得た。すなわち、「拭き取り試験」は上記の拭き取り性を評価するための試験であり、「吸い込み試験」は上記の吸引除去性を評価するための試験である。
As a result of the inventor's investigation of dust in the actual facilities in the radiation control area, the content of the dust is partly fibrous, which seems to be derived from clothing, and most of it is a lump with a diameter of about several tens of μm Turned out to be. And in the lump-shaped dust, the water-soluble thing which shows deliquescence, and the water-insoluble thing existed. Therefore, as for the removability of dust containing radioactive substances in the actual equipment, it was found that it is necessary to evaluate the wiping property in a wet state and the suction removability by a vacuum cleaner or the like. That is, the “wiping test” is a test for evaluating the wiping property, and the “suction test” is a test for evaluating the suction removing property.

また、これらの試験において、通常の湿度環境では潮解性を示さない(相対湿度90%以上で潮解性を示す)が水溶性である平均粒径が80μm以下の物質、たとえば50μm程度の硫酸カリウムの微小粉末を、共通の「模擬汚れ物質」として用いることが好適である。   Further, in these tests, substances that do not show deliquescence in a normal humidity environment (show deliquescence at a relative humidity of 90% or more) but are water-soluble and have an average particle size of 80 μm or less, for example, about 50 μm of potassium sulfate. It is preferred to use the fine powder as a common “simulated soil substance”.

上記の2通りの方法による除塵性およびRvkの相関関係は高く、Rvkが上記の所定の範囲内にある塗膜は、拭き取り試験結果、吸い込み試験結果、および繊維付着試験結果について上記の所定の条件を満たす塗膜とほぼ同等の除塵性を有するものといえる。   The correlation between dust removal property and Rvk by the above two methods is high, and the coating film in which Rvk is in the above-mentioned predetermined range is the above-mentioned predetermined condition for the wiping test result, the suction test result, and the fiber adhesion test result. It can be said that it has almost the same dust removal performance as a coating film satisfying the above.
