Description

本発明は、一液型の速乾性水性塗料組成物、特に路面表示用速乾性水性塗料組成物に関する。   The present invention relates to a one-pack type quick-drying aqueous coating composition, and more particularly to a quick-drying aqueous coating composition for road surface display.

路面表示用塗料は、道路、駐車場などのコンクリートやアスファルト表面への車線、駐車スペースなどの表示や文字による指示などのために使用される特殊な塗料である。
この路面表示用塗料は、貯蔵安定性がよく、塗布後は速乾性で密着性、耐候性、耐摩耗性が高いといった特性が要求されるが、特に重要な性質は、貯蔵安定性と塗布後の乾燥性である。塗布後の乾燥に至るまでの時間は、道路等における車の通交遮断時間を意味するので、車の通交量の大きな道路では、できる限り乾燥時間の短い塗料が要求される。
易揮発性の有機溶剤を用いた速乾性塗料は、塗布後迅速に乾燥するが、溶剤蒸気による作業者および環境への悪影響が懸念されるうえ、引火の危険性も大きい。そこでこれらの有機溶剤系塗料に代わって種々の水性塗料が検討されてきた。
一般に水性塗料は有機溶剤系塗料に比して乾燥に至る時間が長く、特に低温下や高湿下では、乾燥までに数時間以上を要することもある。そこで、一液型でありながら貯蔵安定性が高く、塗布後の乾燥時間が短く、路面への密着性、耐摩耗性および耐水性の良好な路面表示水性塗料が強く求められ、これまでにもいくつかの提案がなされてきた。
The road surface display paint is a special paint used for displaying roads, parking lots, etc., lanes on asphalt surfaces, parking spaces, etc., and indicating characters.
This road surface display paint has good storage stability, and after application, it is required to have characteristics such as quick-drying and high adhesion, weather resistance, and abrasion resistance. Particularly important properties are storage stability and after application. Is dry. Since the time from application to drying means the time for blocking traffic on a road or the like, a paint having a short drying time as much as possible is required on a road with a large amount of traffic.
A quick-drying paint using a readily volatile organic solvent dries quickly after application, but there is a concern that the solvent vapor may adversely affect workers and the environment, and there is a high risk of ignition. Accordingly, various water-based paints have been studied in place of these organic solvent-based paints.
In general, water-based paints take longer to dry than organic solvent-based paints, and may take several hours or more to dry, particularly at low temperatures and high humidity. Therefore, there is a strong demand for road surface display water-based paints that are high in storage stability, short in drying time after application, have good adhesion to the road surface, wear resistance, and water resistance, although they are one-pack type. Several proposals have been made.

それらの技術の1つに、塗料の隠蔽性、反射性および乾燥性の向上を目的として、内部が空洞、すなわち内部が空気で満たされている中空ポリマー微粒子と造膜性樹脂水分散体(本明細書においては、バインダー粒子分散体と実質的に同義に用いられる。)を同時または別々に路面に塗布する路面表示用水性塗料が提案されている(特許文献1、特許文献2)。これらは、塗布後、中空ポリマー微粒子の空洞に水分散体中の水分を吸収させ、乾燥を早めるという技術であるが、バインダー粒子水分散体と中空ポリマー微粒子の二成分を使用前から混合すると貯蔵中に水分が中空ポリマーの空隙に移行してきて塗料の粘度が上昇するので、別々に貯蔵しておき、使用時混合するという煩雑な操作が必要である。
さらに、上記バインダー粒子水分散体と中空ポリマー微粒子を含む水性塗料組成物において、中空ポリマー微粒子に揮発物質の水溶液を内包させておき、塗布後は、中空ポリマー微粒子内の揮発性物質とバインダー粒子水分散体中の水を入れ替えることにより乾燥を早めるという技術も知られている(特許文献3)。
特開2001−212504号 特開2002−30257号 特開2004−263001号
One of these techniques is to improve the concealability, reflectivity, and drying properties of paints by forming hollow polymer fine particles whose interior is hollow, that is, filled with air, and a film-forming resin water dispersion (this In the specification, a water surface paint for road surface display is proposed (Patent Document 1 and Patent Document 2), which are applied to the road surface simultaneously or separately. These are technologies that, after coating, the water in the water dispersion is absorbed in the hollow of the hollow polymer fine particles and the drying is accelerated, but when the two components of the binder particle aqueous dispersion and the hollow polymer fine particles are mixed before use, they are stored. Since moisture moves into the voids of the hollow polymer and the viscosity of the paint rises, a complicated operation of storing separately and mixing at the time of use is necessary.
Further, in the aqueous coating composition containing the binder particle aqueous dispersion and the hollow polymer fine particles, the hollow polymer fine particles are encapsulated with an aqueous solution of a volatile substance, and after coating, the volatile substance in the hollow polymer fine particles and the binder particle water are contained. A technique is also known in which drying is accelerated by replacing water in the dispersion (Patent Document 3).
