Title (EN) METHOD FOR FORMING MULTILAYER COATING FILM
(FR) PROCÉDÉ DE FORMATION D’UN FILM DE REVÊTEMENT MULTICOUCHE
(JA) 複層塗膜形成方法
Abstract:
(EN) Provided is a method for forming a multilayer coating film, which is capable of forming a multilayer coating film that exhibits excellent curability at low temperatures, while having excellent hardness and excellent finish appearance. A method for forming a multilayer coating film, which sequentially performs: (1) a step for forming an uncured first color coating film by applying a two-package type aqueous first color coating material (X) onto an object to be coated; (2) a step for forming an uncured second color coating film by applying a one-package type aqueous second color coating material (Y) onto the uncured first color coating film obtained in the step (1); (3) a step for forming an uncured clear coating film by applying a two-package type clear coating material (Z) onto the uncured second color coating film obtained in the step (2); and (4) a step for curing the uncured first color coating film, the uncured second color coating film and the uncured clear coating film, which are formed in the steps (1)-(3), at the same time by heating these coating films. This method for forming a multilayer coating film is configured such that the one-package type aqueous second color coating material (Y) contains a specific hydroxyl group-containing acrylic resin (Y1), a specific hydroxyl group-containing polyester resin (Y2), and a blocked polyisocyanate compound and/or a melamine resin (Y3).
(FR) L'invention concerne un procédé de formation d'un film de revêtement multicouche, qui est en mesure de former un film de revêtement multicouche qui présente une excellente aptitude au durcissement aux basses températures, tout en présentant une excellente dureté et un excellent aspect de finition. L'invention porte sur un procédé de formation d'un film de revêtement multicouche, qui effectue séquentiellement : (1) une étape consistant à former un premier film de revêtement de couleur non durci par application d'un premier matériau de revêtement de couleur aqueux de type à deux composants (X) sur un objet à revêtir ; (2) une étape consistant à former un deuxième film de revêtement de couleur non durci par application d'un deuxième matériau de revêtement de couleur aqueux de type à un composant (Y) sur le premier film de revêtement de couleur non durci obtenu à l'étape (1) ; (3) une étape consistant à former un film de revêtement transparent non durci par application d'un matériau de revêtement transparent de type à deux composants (Z) sur le deuxième film de revêtement de couleur non durci obtenu à l'étape (2) ; et (4) une étape consistant à faire durcir le premier film de revêtement de couleur non durci, le deuxième film de revêtement de couleur non durci et le film de revêtement transparent non durci, qui sont formés dans les étapes (1) à (3), en même temps par chauffage de ces films de revêtement. Ce procédé de formation d'un film de revêtement multicouche est conçu de telle sorte que le deuxième matériau de revêtement de couleur aqueux de type à un composant (Y) contient une résine acrylique spécifique contenant un groupe hydroxyle (Y1), une résine de polyester spécifique contenant un groupe hydroxyle spécifique (Y2) et un composé polyisocyanate bloqué et/ou une résine de mélamine (Y3).
(JA) 低温硬化性に優れ、硬度、仕上り外観に優れた複層塗膜が形成できる複層塗膜形成方法を提供する。被塗物上に、(1)水性2液型第1着色塗料(X)を塗装して未硬化の第1着色塗膜を形成する工程、(2)工程(1)で得られた未硬化の第1着色塗膜上に水性1液型第2着色塗料(Y)を塗装して未硬化の第2着色塗膜を形成する工程、(3)工程(2)で得られた未硬化の第2着色塗膜上に2液型クリヤ塗料(Z)を塗装して未硬化のクリヤ塗膜を形成する工程、ならびに(4)工程(1)~(3)で形成された未硬化の第1着色塗膜、未硬化の第2着色塗膜及び未硬化のクリヤ塗膜を加熱することによって、これら塗膜を同時に硬化させる工程、を順次行なう複層塗膜形成方法であって、上記水性1液型第2着色塗料(Y)が、特定の水酸基含有アクリル樹脂(Y1)、特定の水酸基含有ポリエステル樹脂(Y2)及びブロックポリイソシアネート化合物及び/又はメラミン樹脂(Y3)を含有する、複層塗膜形成方法。
