Description
本発明者らは、上記の問題を解決すべく鋭意研究した結果、疎水性微粒子を含むコーティング組成物に熱膨張性マイクロカプセルを所定の方法及び割合にて配合することにより、加熱するだけでコーティング膜の撥水性を容易に回復させることができるコーティング組成物が得られることを見出した。
すなわち、本発明は、溶剤に溶解したバインダー樹脂に分散された疎水性微粒子及び熱膨張性マイクロカプセルを含むコーティング組成物であって、前記溶剤に溶解した前記バインダー樹脂に前記疎水性微粒子のみが高圧分散されており、前記バインダー樹脂に対する前記疎水性微粒子の質量比が０．４以上であり、且つ前記バインダー樹脂に対する前記熱膨張性マイクロカプセルの質量比が０．０５以上であることを特徴とするコーティング組成物である。
As a result of diligent research to solve the above-mentioned problems, the inventors of the present invention incorporated a thermally expandable microcapsule into a coating composition containing hydrophobic fine particles in a predetermined method and a ratio, thereby coating the coating composition only by heating. It was found that a coating composition capable of easily recovering the water repellency of the film was obtained.
That is, the present invention is a coating composition comprising hydrophobic fine particles dispersed in a binder resin dissolved in a solvent and thermally expandable microcapsules, wherein only the hydrophobic fine particles are added to the binder resin dissolved in the solvent. Dispersed, wherein the mass ratio of the hydrophobic fine particles to the binder resin is 0.4 or more, and the mass ratio of the thermally expandable microcapsules to the binder resin is 0.05 or more. It is a coating composition.
また、本発明は、溶剤に溶解したバインダー樹脂に高圧分散装置を用いて疎水性微粒子を分散させた後、熱膨張性マイクロカプセルを混合攪拌するコーティング組成物の製造方法であって、前記バインダー樹脂に対する前記疎水性微粒子の質量比が０．４以上であり、且つ前記バインダー樹脂に対する前記熱膨張性マイクロカプセルの質量比が０．０５以上であることを特徴とするコーティング組成物の製造方法である。
また、本発明は、基材と、前記基材上に形成されたコーティング膜であって、前記コーティング組成物の乾燥物であるコーティング膜とを有することを特徴とするコーティング物品である。
さらに、本発明は、前記コーティング物品に形成されたコーティング膜の撥水性が低下した場合に、前記コーティング膜を加熱することによって撥水性を回復させることを特徴とするコーティング膜の回復方法である。
The present invention also relates to a method for producing a coating composition, in which hydrophobic fine particles are dispersed in a binder resin dissolved in a solvent using a high-pressure dispersing device, and then thermally expandable microcapsules are mixed and stirred. A method for producing a coating composition, wherein a mass ratio of the hydrophobic microparticles to 0.4 is 0.4 or more, and a mass ratio of the thermally expandable microcapsules to the binder resin is 0.05 or more. .
The present invention also provides a coated article comprising a substrate and a coating film formed on the substrate, the coating film being a dried product of the coating composition.
Furthermore, the present invention is the coating film recovery method, wherein when the water repellency of the coating film formed on the coated article is lowered, the water repellency is recovered by heating the coating film.
