特許文献３として示す、特開２００４−１８２９１７号公報は、本件出願人が出願人に一人となる発明であり、水性の路面標示用塗料組成物の開示がある。特許文献３の主たる特徴は、エマルション系の水性塗料中に、無機充填材（顔料を除く。）が配合されてなる路面標示用の塗料組成物において、前記無機充填材の一部として、モース硬度５以上を示す硬質無機充填材が、塗面に耐摩耗性を付与可能な量配合されてなることにあり、路面標示用塗料の耐摩耗性を改良したものにあった。 Japanese Patent Application Laid-Open No. 2004-182917 shown as Patent Document 3 is an invention in which the present applicant is one of the applicants, and discloses an aqueous road marking coating composition. The main feature of Patent Document 3 is that, in a paint composition for road marking, in which an inorganic filler (excluding pigment) is blended in an emulsion-based aqueous paint, Mohs hardness is used as a part of the inorganic filler. The hard inorganic filler showing 5 or more is blended in an amount capable of imparting wear resistance to the coated surface, and the wear resistance of the road marking paint is improved.
水性路面標示塗料は水分が蒸発しないと塗膜の成膜が行われないため、乾燥時間は、塗布の際の気温や湿度といった周囲の環境に大きく依存するものである。特に湿度が高い環境下の施工においては、水性路面標示塗料は乾燥時間に数時間程度要することがあり、係る時間、道路の交通規制を行わなければならないという問題がある。 Since the water-based road marking paint does not form a coating unless moisture evaporates, the drying time greatly depends on the surrounding environment such as temperature and humidity at the time of application. Especially in construction under high humidity environment, the water-based road marking paint may require several hours for drying time, and there is a problem that traffic control of the road must be performed for such time.
上記の水性路面標示塗料の乾燥時間の問題を解決するためにいくつかの提案がなされている。例えば、特許文献４（特開２００４−２４４４６７号公報）では、路面に塗布された路面標示用水性塗料の塗膜上に路面標示用水性塗料定着剤を散布する路面標示の形成方法が開示されている。そして、路面標示用水性塗料定着剤として、酸化カルシウム、酸化バリウム及び酸化ストロンチウムなどの水と反応することで発熱可能な無機化合物粒子が開示されている。 Several proposals have been made to solve the problem of the drying time of the water-based road marking paint. For example, Patent Document 4 (Japanese Patent Application Laid-Open No. 2004-244467) discloses a road marking forming method in which a road marking aqueous paint fixing agent is sprayed on a coating film of a road marking aqueous paint applied to a road surface. Yes. In addition, inorganic compound particles capable of generating heat by reacting with water such as calcium oxide, barium oxide, and strontium oxide are disclosed as water marking agents for road marking.
特許文献４（特開２００４−２４４４６７号公報）に記載された発明においては、定着剤としての無機化合物粒子が水と反応することによって発熱し、塗料の乾燥性を促進するものである。しかし、定着剤が接触している塗料の周辺は定着剤が発熱することによって乾燥性が促進されるものの、発熱が終了すると乾燥性は促進されないため、定着剤の散布量が少ない場合には塗料の乾燥性が充分でない恐れがある。また、定着剤としての無機化合物粒子が水と反応するため、定着剤は長期の保存の際に空気中の水分と反応し、定着剤が変化する恐れがある。特に酸化カルシウム、酸化バリウム及び酸化ストロンチウムは、従来より乾燥剤として好んで使用されるものであり、長期の保存の際には密閉して保管する必要があるなど、取り扱いが困難であるという問題がある。 In the invention described in Patent Document 4 (Japanese Patent Application Laid-Open No. 2004-244467), the inorganic compound particles as a fixing agent generate heat by reacting with water and promote the drying property of the paint. However, although the drying property is promoted by the heat generated by the fixing agent in the vicinity of the paint in contact with the fixing agent, the drying property is not promoted when the heat generation is completed. There is a possibility that the dryness of the is not sufficient. In addition, since the inorganic compound particles as the fixing agent react with water, the fixing agent reacts with moisture in the air during long-term storage, and the fixing agent may change. In particular, calcium oxide, barium oxide, and strontium oxide are conventionally preferred as desiccants and have a problem that they are difficult to handle because they need to be sealed and stored for long-term storage. is there.
この発明は、上記のような従来技術に存在する問題点に着目してなされたものである。その目的とするところは、塗料の乾燥性を促進することを目的とする取り扱いの容易な水性路面標示塗料用硬化促進剤、水性路面標示塗料用硬化促進剤分散液及び当該硬化促進剤の使用に適した水性路面標示塗料、とこれらの施工に適した塗装方法を提供することにある。 The present invention has been made paying attention to the problems existing in the prior art as described above.

以下、この発明の水性路面標示塗料用硬化促進剤（以下、「本発明の硬化促進剤」という）及び水性路面標示塗料（以下、「本発明の塗料」という）及び水性路面表示塗料の塗布方法（以下、「本発明の方法」という）について詳細に説明する。 Hereinafter, the curing accelerator for water-based road marking paints (hereinafter referred to as “the curing accelerator of the present invention”), the water-based road marking paint (hereinafter referred to as “the paint of the present invention”) and the method for applying the water-based road marking paint according to the present invention. (Hereinafter referred to as “the method of the present invention”) will be described in detail.
本発明の硬化促進剤は、水に不溶でありアルカリ水溶液に可溶である金属化合物である。この硬化促進剤を用いることにより、塗料の乾燥性を促進することができる。水に不溶とは、金属化合物が、故意に他の物質を溶解させた水溶液ではない水に不溶であることをいう。水は、他の物質が溶けていることによって溶解力が増す性質を有している。したがって、故意に他の物質を溶解させた水溶液ではない水にまで不溶であることを要するものではない。なお、水は非常に物質を溶かしやすい液体であるため、１×１０−３（ｇ／１００ｇ・Ｈ２Ｏ）以下の溶解は、本発明では水に不溶であるとする。アルカリ水溶液に可溶であるとは、金属化合物が、故意に他の物質を溶かすことによってアルカリ性に調整された水溶液に可溶であることをいう。詳しくは、アルカリ水溶液の水素イオン濃度（以下、ｐＨとする。）が８以上で可溶であるものが好ましい。 The curing accelerator of the present invention is a metal compound that is insoluble in water and soluble in an alkaline aqueous solution. By using this curing accelerator, the drying property of the paint can be promoted. The term “insoluble in water” means that the metal compound is insoluble in water that is not an aqueous solution in which another substance is intentionally dissolved. Water has the property of increasing its dissolving power by dissolving other substances. Therefore, it is not required to be insoluble even in water that is not an aqueous solution in which other substances are intentionally dissolved. In addition, since water is a liquid that easily dissolves a substance, it is assumed that dissolution of 1 × 10 −3 (g / 100 g · H 2 O) or less is insoluble in water in the present invention. Being soluble in an aqueous alkali solution means that the metal compound is soluble in an aqueous solution adjusted to be alkaline by deliberately dissolving other substances. Specifically, it is preferable that the aqueous alkali solution has a hydrogen ion concentration (hereinafter referred to as pH) of 8 or more and is soluble.
本発明の硬化促進剤としての金属化合物として、金属酸化物または金属水酸化物が挙げられ、これらの中には水に不溶でありアルカリ水溶液に可溶である性質を有するものが多く、塗料の乾燥性を促進することができる。 Examples of the metal compound as the curing accelerator of the present invention include metal oxides or metal hydroxides, and many of these have properties that are insoluble in water and soluble in an alkaline aqueous solution. Dryability can be promoted.
本発明の硬化促進剤としての金属酸化物として、亜鉛酸化物、カドミウム酸化物、マグネシウム酸化物、ベリリウム酸化物が挙げられ、具体的には、酸化亜鉛、酸化カドミウム、酸化マグネシウム、酸化ベリリウムを使用することができる。また、金属水酸化物として、水酸化亜鉛、水酸化銅を使用することができる。これらは１種類単独でも２種類を混合しても本発明の硬化促進剤として使用することができる。これらは、水に不溶でありアルカリ水溶液に可溶である性質を有し、水に不溶であるため、空気中の水分と反応することがなく、硬化促進剤の長期の保存の際に、硬化促進剤の変化が少ないという利点を有している。これら金属化合物の中でも、酸化亜鉛、酸化マグネシウム、水酸化亜鉛および水酸化マグネシウムが市場において一般に流通しており価格が安価であるため、本発明の硬化促進剤として好適に使用することができ、特に酸化亜鉛および酸化マグネシウムは、市場において大量に流通しているため、より好適に使用することができる。 Examples of the metal oxide as the curing accelerator of the present invention include zinc oxide, cadmium oxide, magnesium oxide, and beryllium oxide. Specifically, zinc oxide, cadmium oxide, magnesium oxide, and beryllium oxide are used. can do. The metal hydroxides, zinc hydroxide, water copper oxide can be used. These can be used as the curing accelerator of the present invention alone or in combination of two. These have the property of being insoluble in water and soluble in alkaline aqueous solution, and are insoluble in water. It has the advantage that the change of the accelerator is small. Among these metal compounds, zinc oxide, magnesium oxide, zinc hydroxide and magnesium hydroxide are generally distributed in the market and are inexpensive, and can be suitably used as the curing accelerator of the present invention. Since zinc oxide and magnesium oxide are distributed in large quantities in the market, they can be used more suitably.
また、本発明の硬化促進剤の平均粒子径は、０．２〜１０００μｍであることが好ましい。好適に硬化促進剤を散布することができ、塗料が成膜・固化してなる塗膜の仕上がりも良いためである。０．２μｍ未満だと本発明の塗料に散布する際に硬化促進剤が空気中に舞い、散布が困難となる恐れがある。一方、１０００μｍ超だと本発明の塗料に散布した際に硬化促進剤が粒子として残り、塗膜の仕上がりが良くならない恐れがある。より好ましくは、平均粒子径が５〜５００μｍにある硬化促進剤である。上記の利点に加え、入手が容易となるからである。 Moreover, it is preferable that the average particle diameter of the hardening accelerator of this invention is 0.2-1000 micrometers. This is because the curing accelerator can be suitably sprayed, and the finish of the coating film formed by coating and solidifying the paint is also good. If it is less than 0.2 μm, the curing accelerator may float in the air when sprayed on the paint of the present invention, which may make it difficult to spray. On the other hand, there is a possibility that the curing accelerator upon spraying the paint of the present invention that it 1000μm than does not remain, the finish of the coating film may as particles. More preferably, it is a curing accelerator having an average particle diameter of 5 to 500 μm. This is because in addition to the above advantages, it is easy to obtain.
また、本発明の硬化促進剤を、水に分散させた硬化促進剤分散液として使用することもできる。この硬化促進剤分散液を用いることにより、硬化促進剤の散布を容易に行うことができる。粒子である硬化促進剤より水に分散させた硬化促進剤分散液の方が散布が容易であるからである。 Moreover, the hardening accelerator of this invention can also be used as a hardening accelerator dispersion liquid dispersed in water. By using this curing accelerator dispersion, it is possible to easily spray the curing accelerator. This is because the dispersion of the curing accelerator dispersed in water is easier to disperse than the curing accelerator as particles.
水とは、水道水や井戸水など容易に入手することができるものを含み、精製水やイオン交換水などに限定されるものではない。水には必要に応じ、硬化促進剤の分散を安定にする分散剤、水の揮発を早めるためにメタノール、エタノール、アセトンまたは酢酸エチルといった低沸点有機溶剤を添加することができる。また、硬化促進剤分散液を安定にするための添加剤として湿潤剤、消泡剤、凍結防止剤及び増粘剤を必要に応じ添加することもできる。 The water includes easily available water such as tap water and well water, and is not limited to purified water or ion exchange water. If necessary, a dispersing agent that stabilizes the dispersion of the curing accelerator and a low-boiling organic solvent such as methanol, ethanol, acetone, or ethyl acetate can be added to water to accelerate the volatilization of water. In addition, wetting agents, antifoaming agents, antifreezing agents, and thickeners can be added as necessary as additives for stabilizing the curing accelerator dispersion.
硬化促進剤分散液における本発明の硬化促進剤の分散割合としては、１５〜６０重量％程度が好ましい。硬化促進剤分散液を散布されることによって塗料が十分に成膜・固化させることができ、また、硬化促進剤分散液における硬化促進剤の分散が安定であるためである。１５％未満だと硬化促進剤分散液が散布された塗料が十分に成膜・固化しない恐れがあり、一方、６０重量％超だと、硬化促進剤分散液における硬化促進剤の分散が不安定になり硬化促進剤の沈降などが生じる恐れがある。 The dispersion ratio of the curing accelerator of the present invention in the curing accelerator dispersion is preferably about 15 to 60% by weight. This is because the coating film can be sufficiently formed and solidified by spraying the curing accelerator dispersion, and the dispersion of the curing accelerator in the curing accelerator dispersion is stable. There is a risk that the paint curing accelerator dispersion and less than 15% is sprayed is not sufficiently deposited and solidified, whereas, if it 60 wt.%, Unstable dispersion of the curing accelerator in the curing accelerator dispersion liquid There is a risk that precipitation of the curing accelerator may occur.
本発明の塗料は、本発明の硬化促進剤が散布されることによって成膜・固化する合成樹脂エマルションを結合材として含有すること、および、揮発性塩基を含有することにより塗料のｐＨが１０以上１２以下の範囲に調整されている水性路面標示塗料である。 The paint of the present invention contains a synthetic resin emulsion that forms a film and solidifies by being sprayed with the curing accelerator of the present invention as a binder, and the pH of the paint is 10 or more by containing a volatile base. It is an aqueous road marking paint adjusted to a range of 12 or less.
本発明の硬化促進剤が散布されることによって成膜・固化する合成樹脂エマルションとは、本発明の硬化促進剤が溶けることによって生じる金属イオンによって合成樹脂エマルションが成膜・固化する合成樹脂エマルションをいう。具体的には、陰イオンによって安定化された乳化重合体を含有する合成樹脂エマルションが好ましく、陰イオンとしては、陰イオン性界面活性剤、陰イオン性官能基又はアニオン性官能基などが好適に使用することができる。本発明の塗料により、本発明の硬化促進剤が散布されることによって、塗料の乾燥性を促進することができる。本発明の塗料に本発明の硬化促進剤を散布することによって、本発明の硬化促進剤の金属化合物が当該水性塗料に溶け、金属化合物の金属が陽イオンとなって、陰イオンによって安定化された乳化重合体を含有する合成樹脂エマルションが不安定になり、成膜・固化すると考えられるからである。 The synthetic resin emulsion that is formed and solidified by spraying the curing accelerator of the present invention is a synthetic resin emulsion in which the synthetic resin emulsion is formed and solidified by metal ions generated by the dissolution of the curing accelerator of the present invention. Say. Specifically, a synthetic resin emulsion containing an emulsion polymer stabilized by an anion is preferable, and an anionic surfactant, an anionic functional group, or an anionic functional group is suitably used as the anion. Can be used. By spreading the curing accelerator of the present invention by the paint of the present invention, the drying property of the paint can be promoted. By spreading the curing accelerator of the present invention on the paint of the present invention, the metal compound of the curing accelerator of the present invention is dissolved in the aqueous paint, and the metal of the metal compound becomes a cation and stabilized by an anion. This is because it is considered that the synthetic resin emulsion containing the emulsion polymer becomes unstable and forms a film and solidifies.
揮発性塩基を含有することにより塗料のｐＨが１０以上１２以下の範囲に調整された水性路面標示塗料とは、揮発性塩基の添加によりｐＨが１０以上１２以下の範囲に調整した水性路面標示塗料をいう。本発明の塗料のｐＨが１０以上１２以下の範囲にあることによって、塗料物性が劣ることなく、本発明の塗料に本発明の硬化促進剤は容易に溶かすことができる。なお、ｐＨが１０未満では、本発明の硬化促進剤が十分に溶けない恐れがあり、一方、ｐＨが１２を越える値では、添加される揮発性塩基の量が多くなり、水性路面標示塗料の粘度、固形分といった塗料物性が劣る恐れがある。 An aqueous road marking paint whose pH is adjusted to a range of 10 to 12 by containing a volatile base is an aqueous road marking paint whose pH is adjusted to a range of 10 to 12 by adding a volatile base. Say. When the pH of the paint of the present invention is in the range of 10 or more and 12 or less, the curing accelerator of the present invention can be easily dissolved in the paint of the present invention without inferior properties of the paint. If the pH is less than 10, the curing accelerator of the present invention may not be sufficiently dissolved. On the other hand, if the pH exceeds 12, the amount of volatile base to be added increases, and the aqueous road marking paint There is a fear that the physical properties of the paint such as viscosity and solid content are inferior.
揮発性塩基とは、塗料の成膜・固化の際に揮発する塩基をいう。揮発性塩基を用いることによって、成膜した塗料に塩基が残ることがないため、塗料が成膜・固化した塗膜の耐水性・耐アルカリ性といった塗膜物性が良好なものとなる。一方、塗料の成膜・固化の際に揮発しない塩基を用いた場合には、塗料が成膜・固化した塗膜に塩基が残るため、耐水性、耐アルカリ性といった、塗膜物性が満たされない恐れがある。好ましい揮発性塩基は、入手が容易なアンモニア水で、沸点は約４０℃（２５％）である。その他、低級アルキルアミン、エチレンジアミンなど、またはこれらの混合物も好適に使用することができる。 The volatile base refers to a base that volatilizes when a coating is formed and solidified. By using a volatile base, the base does not remain in the coating film formed, so that the coating film properties such as water resistance and alkali resistance of the coating film on which the coating film is formed and solidified are excellent. On the other hand, if a base that does not volatilize during film formation and solidification of the paint is used, the base remains in the paint film on which the paint has been formed and solidified, and the physical properties of the film, such as water resistance and alkali resistance, may not be satisfied. There is. A preferred volatile base is ammonia water, which is readily available, and has a boiling point of about 40 ° C. (25%). In addition, lower alkyl amines, ethylene diamines, and the like, or mixtures thereof can also be suitably used.
本発明の塗料は、本発明の硬化促進剤が散布されることによって成膜・固化する合成樹脂エマルションに、充填材として炭酸カルシウム、着色顔料として二酸化チタンを混合させた塗料である。本発明の塗料には塗料物性及び作業性などを向上させるために、分散剤、湿潤剤、消泡剤、凍結防止剤、増粘剤及び成膜助剤を必要に応じて加えることができる。なお、本発明の塗料は、本発明の硬化促進剤が散布されることによって、塗料の乾燥性を促進することができるものであるが、本発明の硬化促進剤が散布されない場合であっても、塗料の乾燥性が促進されないだけであって塗料が成膜・固化することに変わりはない。 The coating material of the present invention is a coating material obtained by mixing calcium carbonate as a filler and titanium dioxide as a coloring pigment in a synthetic resin emulsion that is formed and solidified by spraying the curing accelerator of the present invention. A dispersant, a wetting agent, an antifoaming agent, an antifreezing agent, a thickening agent, and a film forming auxiliary agent can be added to the coating material of the present invention as required in order to improve the physical properties and workability of the coating material. In addition, although the coating accelerator of this invention can accelerate | stimulate the drying property of a coating material by spraying the hardening accelerator of this invention, even if it is a case where the hardening accelerator of this invention is not sprayed. However, the drying of the paint is not promoted, and the paint is still formed and solidified.
本発明の塗装方法とは、本発明の硬化促進剤を本発明の塗料と共に路面に塗布することを特徴とする水性路面表示塗料の塗布方法である。本発明の硬化促進剤を本発明の塗料と共に路面に塗布するとは、本発明の硬化促進剤と本発明の塗料を同時に同じ箇所に塗布及び散布することをいい、これにより、本発明の塗料に本発明の硬化促進剤を好適に溶かすことができ、塗料の乾燥性を促進することができる。なお、本発明の塗布方法は、これに限定されることなく、例えば、本発明の硬化促進剤を、本発明の塗料の塗布に際し予め散布する方法であっても、路面に塗布された本発明の塗料上に後から散布する方法であっても、本発明の塗料に本発明の硬化促進剤を好適に溶かすことができる限り、同じように塗料の乾燥性を促進することができる。 The coating method of the present invention is an application method of an aqueous road surface display paint characterized by applying the curing accelerator of the present invention to a road surface together with the paint of the present invention. Applying the curing accelerator of the present invention to the road surface together with the paint of the present invention means that the curing accelerator of the present invention and the paint of the present invention are simultaneously applied and sprayed on the same location, thereby providing the paint of the present invention. The curing accelerator of the present invention can be suitably dissolved, and the drying property of the paint can be promoted. Note that the coating method of the present invention is not limited to this. For example, the coating method of the present invention is applied to the road surface even if the curing accelerator of the present invention is pre-sprayed when applying the paint of the present invention. Even if it is the method of spraying later on the coating material, the drying property of the coating material can be promoted in the same manner as long as the curing accelerator of the present invention can be suitably dissolved in the coating material of the present invention.
本発明の硬化促進剤の塗料への散布量は、塗料に対し０．５〜５重量％程度が好ましい。塗料を好適に成膜・固化させることができ、また、塗料が成膜・固化した塗膜の物性が満たされたものとなるからである。０．５重量％未満だと塗布された塗料を十分に成膜・固化することができない恐れがあり、一方、５重量％超だと塗料が成膜・固化した塗膜の視感反射率が劣るといった、塗膜の物性が満たされない恐れがある。なお、硬化促進剤の散布量は、硬化促進剤である金属化合物の散布量を表し、硬化促進剤分散液である場合には溶媒分の塗布量を含まないものとする。 The amount of the curing accelerator of the present invention applied to the coating is preferably about 0.5 to 5% by weight based on the coating. This is because the paint can be suitably formed and solidified, and the physical properties of the coating film obtained by forming and solidifying the paint are satisfied. There may not be sufficiently deposited and solidified The applied paint with less than 0.5 wt%, whereas, 5 wt.% But with paint luminous reflectance of the film-forming and solidifying the coating film The physical properties of the coating film, such as inferior, may not be satisfied. In addition, the application amount of the curing accelerator represents the application amount of the metal compound that is the hardening accelerator, and in the case of the hardening accelerator dispersion, the application amount of the solvent is not included.
水性路面標示塗料用硬化促進剤と、水性路面標示塗料からなる路面標示塗料セットとは、本発明の硬化促進剤と本発明の塗料からなる組み合わせからなるセットである。この路面標示塗料セットを用いることにより、本発明の塗装方法を好適に実施することができる。 The curing accelerator for water-based road marking paints and the road marking paint set comprising an aqueous road marking paint are a set comprising a combination of the curing accelerator of the present invention and the paint of the present invention. By using this road marking paint set, the coating method of the present invention can be suitably carried out.
以下、本発明の実施例及び比較例に基づいて、本発明をより具体的に説明する。
なお、比較例４を除く、塗料の結合材としての合成樹脂エマルションには、ローム・アンド・ハース社製の「Ｆａｓｔｒａｃｋ５３」を使用した。この合成樹脂エマルションは、本発明の硬化促進剤によって好適に成膜・固化する合成樹脂エマルションである。ただし、これに限定されることなく、本発明の硬化促進剤によって成膜・固化する合成樹脂エマルションであれば、本発明の効果を達成し得る。

However, without being limited thereto, the effect of the present invention can be achieved as long as it is a synthetic resin emulsion that forms and solidifies with the curing accelerator of the present invention.

This acrylic synthetic resin emulsion is not a synthetic resin emulsion that is formed into a film and solidified by the curing accelerator of the present invention. As the road marking paint, a paint whose pH was adjusted to 11 by adding 0.2% by weight of aqueous ammonia (25%) was used.
（乾燥時間）
１５分以上経過しても塗料が乾燥することはなかった。本発明の硬化促進剤によって成膜・固化する合成樹脂エマルションではないためと考えられる。
(Drying time)
The paint did not dry after 15 minutes or more. This is presumably because it is not a synthetic resin emulsion that is formed and solidified by the curing accelerator of the present invention.
比較例５
硬化促進剤として酸化亜鉛を使用した。路面標示用塗料は、アミノメチルプロパノールを０．２重量％添加することによって塗料のｐＨが１１に調整した塗料を使用した。なお、アミノメチルプロパノールは、塗料の成膜・固化の際に揮発しない塩基である。
Comparative Example 5
Zinc oxide was used as a curing accelerator. As the road marking paint, a paint whose pH was adjusted to 11 by adding 0.2% by weight of aminomethylpropanol was used. Aminomethylpropanol is a base that does not volatilize when the coating is formed and solidified.
（耐アルカリ性）
塗膜に膨れが見られた。アミノメチルプロパノールが塗料の乾燥過程で揮発せずに塗膜に残ったために、アルカリ溶液に対し塗膜が溶けたものと考えられる。
(Alkali resistance)
The coating film was swollen. It is considered that the coating film was dissolved in the alkaline solution because aminomethylpropanol remained in the coating film without volatilizing during the drying process of the coating material.
比較例６
硬化促進剤として酸化亜鉛を使用した。路面標示用塗料は、アンモニア水（２５％）を３．６重量％添加することによって塗料のｐＨを１２．５に調整した塗料を使用した。
Comparative Example 6
Zinc oxide was used as a curing accelerator. As the road marking paint, a paint whose pH was adjusted to 12.5 by adding 3.6% by weight of aqueous ammonia (25%) was used.
（乾燥時間）
乾燥時間に１０分を要した。アンモニア水（２５％）を３．６重量％添加したために揮発成分が多くなり、塗料の成膜・固化に時間を要したと考えられる。
(Drying time)
The drying time required 10 minutes. Since 3.6% by weight of aqueous ammonia (25%) was added, the amount of volatile components increased, and it is thought that it took time to form and solidify the paint.
