【発明の詳細な説明】
(産業上の利用分野〕
この発明は、短時間焼付可能で保存安定性に優れ、しか
も外観が良好な塗膜を形成しうる絶縁塗料組成物に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) This invention relates to an insulating coating composition that can be baked for a short time, has excellent storage stability, and can form a coating film with a good appearance.
一般に絶縁塗料組成物は、水酸基を有するポリエステル
樹脂、例えば多塩基酸類またはそのエステル類と多価ア
ルコール類とを加熱縮合して得られるポリエステル系樹
脂と、金属アルコキシド系架橋剤およびこれらを溶解す

は、電線の絶縁皮膜等として使用されている。Generally, an insulating coating composition consists of a polyester resin having a hydroxyl group, such as a polyester resin obtained by heating and condensing polybasic acids or their esters, and a polyhydric alcohol, a metal alkoxide crosslinking agent, and a solvent that dissolves them. It is composed of. This type of insulating coating composition is used as an insulating coating for electric wires.
しかしながら、上記従来の絶縁塗料組成物は、電線を走

。このような問題を解決するため、架橋剤量を増加する
と、組成物自体の粘度が高くなって作業性が低下すると
同時に、発泡し易くなり、保存安定性も悪くなる。また
、短時間焼付を可能にするため高温で焼付けると、発泡
し塗膜の外観が悪くなる。However, when the above-mentioned conventional insulating paint composition is applied to the outer periphery of an electric wire while it is running, and baked by passing through a heating furnace in that state, if baking is performed in a short time, crosslinking is insufficient. As a result, the properties of the insulating coating deteriorate. In order to solve such problems, when the amount of crosslinking agent is increased, the viscosity of the composition itself becomes high and workability decreases, and at the same time, foaming becomes easy and storage stability deteriorates. Furthermore, if the paint is baked at a high temperature to enable short baking times, it will foam and the appearance of the coating will deteriorate.
この発明は、このような事情に鑑みなされたもので、保

形成しうる絶縁塗料組成物の提供をその目的とする。The present invention was made in view of the above circumstances, and an object of the present invention is to provide an insulating coating composition that has excellent storage stability, can be baked for a short time, and can form a coating film with a good appearance.
上記の目的を達成するため、この発明の絶縁塗料組成物

とを見出し、この発明に到達した。[Function] The present inventors have conducted a series of studies with the main purpose of preventing an increase in viscosity due to an increase in the amount of cross-linking agent, and have found that when a chelating agent is used, even if the amount of cross-linking agent is increased, the viscosity does not increase. We have found that it is possible to suppress the increase in carbon dioxide levels and eliminate the negative effects associated with it. As a result of further research on this issue, we found that using a chelating agent that does not contain the above-mentioned specific functional groups in its molecular structure as part of the solvent has no negative effect on the crosslinking reaction of the metal alkoxide crosslinking agent. The inventors have discovered that scales can form a coating film with good properties without causing any damage, and have arrived at this invention.

良されない。The presence of NH groups and COOH groups causes an exchange reaction with the alkoxide of the metal alkoxide crosslinking agent and strongly bonds with the metal, which delays the crosslinking of the hydroxyl groups of the polyester resin with the metal alkoxide, making it impossible to bake for a short time, which is undesirable. The amount of such a chelating agent used is preferably 100 parts or more per 100 parts of the metal alkoxide crosslinking agent. If the amount is less than this, the storage stability of the resin will not be improved.

好結果が得られるようになる。As described above, the insulating coating composition of the present invention consists of a polyester resin having hydroxyl groups, a metal alkoxide crosslinking agent, and a solvent, and as part of the solvent, OH groups, S
Since a chelating agent with a boiling point of 140 to 190°C that does not contain H groups, NH groups, and C00I (groups in its molecular structure) is used, the action of the chelating agent provides excellent storage stability and short baking time. Therefore, when used for enamel coatings on electric wires, etc.,
