関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a high film thickness chipping coating composition for a two-coat one-bake coating method suitable for vehicles, chemical plants, and building materials.
［従来の技術］

生するタレ、ワキ（発泡）性の向上を図っている。[Prior Art] Conventionally, as a high film thickness type paint made of a resin and a pigment, there is a disclosure of a paint in which the type of pigment, m1 particle size, etc. are specified (Japanese Patent Laid-Open No. 56-57855). In addition, as a high film thickness type paint, the baking process is performed at a temperature of 50 to 130°C.
There is also a method of baking for 30 minutes and then 10 to 50 minutes at a temperature of 120 to 180°C in two stages (Japanese Unexamined Patent Application Publication No. 1983-1992).
58564). There is also a proposal for a high II thickness paint in which benzoin is added to the paint (Japanese Unexamined Patent Publication No. 16766/1983). The above measures aim to improve the sagging and bubbling (foaming) properties that occur when coating with high film thickness paints.
従来この種のタイプの塗料は２コート２ベーク用であり
２コート１ベーク法の様にプレキュア−（予備焼付）な
しに高膜厚塗料の上に中塗り塗料を塗装した後に焼付し
た場合、塗面に細かい凹凸が発生し塗面の外観を損う。Conventionally, this type of paint was designed for two coats and two bakes, and if an intermediate coat was applied on top of a high film thickness paint without pre-curing (pre-baking) and then baked, as in the two-coat, one-bake method, the paint Fine irregularities occur on the surface, damaging the appearance of the painted surface.
また２コート１ベーク法で良好な塗面外観を得る方法は

塗装模のセツティング時間を３０分以上設ける必要があ

離を５０ＣＩ１１以上離して塗装を行わなければならな
い。さらに加熱残分を高くする方法もあるが塗料の粘度
が高くなり他の塗膜不良のワキ、フクロ、ダスト性が現
れて好ましくない。In addition, the method of obtaining a good painted surface appearance with the 2-coat, 1-bake method is because the coating loses wrinkles and scatters the solvent after painting with a high film thickness.
It is necessary to allow more than 30 minutes for setting the painted pattern, which poses a problem in productivity. Furthermore, in order to prevent the inclusion of millet m during painting and to prevent the solvent from scattering, the distance from the object to be coated must be 50 CI 11 or more when painting. There is also a method of increasing the heating residue, but this is not preferable because it increases the viscosity of the paint and causes other paint film defects such as wrinkles, flakes, and dust.
［発明が解決しようとする問題点］
上記高膜厚型塗料と中塗り塗料とを２コート１ベーク法

を目的とする。[Problems to be Solved by the Invention] A method for preventing appearance defects such as unevenness that occurs on the surface of a paint film when the above-mentioned high film thickness paint and intermediate paint are applied using a two-coat, one-bake method, as well as leveling the paint film. The purpose is to improve sexuality.

料組成物であり、該中塗り塗料は硬化剤がブチル化メラ
ミンであるアルキッド系塗料である。[Means for Solving the Problems] The high film thickness type chipping coating composition of the present invention has a curing agent that is methylated melamine or a mixture of methylated melamine and butylated melamine, and has a PWC of 60 m city% or more and 70% by weight.
It is a high film thickness coating composition containing a non-polar medium boiling point solvent, and the intermediate coating is an alkyd coating whose curing agent is butylated melamine.

剤、反応ガスが抜けた跡が中塗り塗面に残るのを防ぐた
め、中塗り塗膜が硬化しない前に高膜厚塗膜を硬化させ
んとするものである。The curing agent for the above-mentioned high film thickness type paint is mainly methylated melamine, which has a faster reaction rate than the commonly used butylated melamine. In other words, in order to prevent traces of bubbles, solvent, and reactive gases in the chips of high-film paint from remaining on the intermediate coated surface, the high-film thickness paint film is not cured before the intermediate coat has not yet cured. That is.
顔料濃度（ＰＷＣ）が６０重量％未満の場合はワキ、タ
レ性が悪くなりＰＷＣが７０重貴％をこえると耐チッピ
ング性および塗面が悪くなる。If the pigment concentration (PWC) is less than 60% by weight, the wrinkles and sagging properties will be poor, and if the PWC exceeds 70% by weight, the chipping resistance and the painted surface will be poor.

混合溶剤で沸点が１６０〜１９０℃の溶剤である。The non-polar medium boiling point solvent is a solvent such as trimethylbenzene, dimethylethylbenzene, tetramethylbenzene, etc. alone or in combination, and has a boiling point of 160 to 190°C.
上記高膜厚型塗料による塗装塗膜は１００〜３００μの

キッド系塗料である。The intermediate coating is an alkyd-based coating in which the curing agent is butylated melamine, which has a slower reactivity than the methylated melamine used in thick-film coatings.

As the resin, any well-known paint resin can be used, and there are no particular restrictions, but polyester resins, oil-free alkyd resins, urethane resins, acrylic resins, etc. are preferable. As the pigment, necessary extender pigments and coloring pigments are selected and used, and specifically, calcium carbonate, silica, iron oxide, barium sulfate, aluminum silicate, titanium oxide, zinc, etc. can be used.

A 4:4 composition containing less than 70% by weight of a non-polar, medium-boiling solvent, and a butylated melamine curing agent used as an intermediate coating, is applied in a two-coat, one-basis method to prevent underarms and sagging. A coated surface with excellent gloss and image clarity is formed without dust. Furthermore, the setting time for the coated object is about 2 minutes, which improves productivity, and the coating distance is only 30cm+, which has the advantage of being usable with existing equipment.

In Comparative Example 2, the glossiness is even worse than in Comparative Example 1. In Comparative Example 3, the compounded substances are the same as in Example 1, but the pigment concentration PWC is 55% by weight, which is smaller than the value of the present invention, so the coating film, underarm film thickness, and sagging film thickness are small. is easy to occur.
比較例４は逆にＰＷＣ値が本発明より大きい場合であり
ワキ、タレは良いがダスト性が悲く光沢度も低くさらに
鮮映性の値も小さい。Comparative Example 4, on the other hand, has a PWC value larger than that of the present invention, and has good undertones and sagging, but poor dustiness, low gloss, and low image clarity.

塗面が得られることが示されている。Therefore, we used a methylated melamine type curing agent and a non-polar medium boiling point (160-190°C) solvent, and the PWC was 6.
A good high-film thickness dipping surface can be obtained by using a two-coat, one-base coating method using a high-film thickness paint in the range of 0 to 70% by weight and an alkyd resin paint containing a butylated melamine hardener as an intermediate coating. It has been shown that
