本発明は、耐久性に優れた塗膜が得られる粉体塗装用樹
脂組成物に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a resin composition for powder coating that provides a coating film with excellent durability.
（従来の技術）
金属の耐食性を向上させるために、金属に樹脂を塗装し

や酸が侵入して、ブリスターを生じたり、塗膜が剥離す
るおそれもある。そのために、金属の耐食性が低下する
。(Prior Art) In order to improve the corrosion resistance of metal, coated metal bodies in which metal is coated with resin are known. However, when this coated metal body is used for a long period of time under hot water or in the presence of an acid, cracks occur in the resin coating due to residual stress. Additionally, there is a risk that hot water or acid may enter the paint film, causing blisters or peeling of the paint film. Therefore, the corrosion resistance of the metal decreases.
このような欠点を解決するために、塗膜を構成する塗装
用樹脂に充填材を加える試みがなされている。適当な充
填材の添加により、残留応力が低減され、クラックの発
生が防止される。In order to solve these drawbacks, attempts have been made to add fillers to the coating resin constituting the coating film. Addition of appropriate fillers reduces residual stress and prevents cracks from forming.

の熱伝導率を高めて熱拡散を少なくする、ことが考えら
れる。特に、ブリスターの発生には熱拡散の寄与が大き
く、塗膜の熱伝導率を高める方法が好ましい。In addition, to prevent the occurrence of blisters, (i) increase the elasticity of the paint film, (ii) increase the porosity of the paint film to increase the entry route for hot water and acids, and (tii) One possibility is to increase the thermal conductivity of the coating film to reduce heat diffusion. In particular, thermal diffusion has a large contribution to the generation of blisters, and a method of increasing the thermal conductivity of the coating film is preferred.

が発錆する。Such fillers include, for example, carbon fiber (Japanese Patent Publication No. 52
-17534), silicon compounds, metals, and metal oxides (disclosed in Japanese Patent Publication No. 3172/1983). However, carbon fibers, silicon compounds, and metal oxides have lower thermal conductivity than metals, so the occurrence of blisters cannot be completely prevented. Although metal powder has high thermal conductivity, the resulting resin coating will rust because the metal powder itself lacks corrosion resistance.

/11/9/9/2 amorphous alloy powder is preferably used. These amorphous alloy powders have corrosion resistance,
Excellent heat resistance and chemical resistance. Such an alloy powder can be produced by heating and melting a blended alloy material, injecting it by a method such as a spray method, cavitation method, or rotary fluid injection method, and then rapidly cooling it. It can also be obtained by pulverizing a commercially available ribbon-shaped amorphous alloy.

（なる。If it is less than 0.5% by volume, the effect of adding the amorphous alloy powder will be small, making it difficult to obtain a coating film with excellent durability. On the other hand, if it exceeds 15% by volume, the bonding strength of the coating film decreases, and the adhesion between the coating film and objects such as metals is likely to be impaired.

Even if this coating film is exposed to hot water for a long time, no blistering occurs. The coating film obtained by applying a powder coating resin composition that does not contain amorphous alloy powder or a powder coating resin composition that contains carbon fiber or aluminum powder instead of amorphous alloy powder to metal is
Prolonged contact with hot water causes blistering.

。(Effects of the Invention) As described above, the resin composition for powder coating of the present invention contains a coating resin and an amorphous alloy powder, so when it is powder coated on an object such as a metal, it has poor durability. An excellent coating film can be obtained. No blistering occurs when this coating is brought into contact with hot water. Moreover, the paint film will not rust.
