は有機溶剤にによって成される。The treatment of metal powder in the present invention involves dissolving an aluminum-based coupling agent directly into the metal powder or in an organic solvent.
Stir and mix using a mixer, ball mill, etc. to form a uniform thin film of the aluminum coupling agent on the surface of the metal powder. Thereafter, a titanate coupling agent is applied directly or by using an organic solvent.

く、耐湿性が悪くなることがある。The amount of the aluminum coupling agent added is 0.01 to 5% by weight based on the metal powder. The amount of aluminum-based coupling agent added is sufficient to coat the surface of the metal powder as thinly as possible; if it is added in excess, moisture resistance may deteriorate. The amount added is correlated with the surface area of the metal powder, and for metal powders with a small surface area, an effect is recognized from 0.01% by weight, but it is necessary to add more for metal powders with a large surface area. If it is added in an amount of 5% by weight or more, the aluminum-based coupling agent will be in an excessive state, and the effect of the present invention of pre-treatment with an aluminum-based coupling agent may be reduced, resulting in poor moisture resistance.
チタネート系カップリング剤の添加量は金属粉に対して
０．０２〜２５重量％であり、チタネート系カップリン
グ剤の添加量は金属粉表面を被覆できる量であれば良く
、アルミニウム系カップリング剤はど限定はされない。The amount of the titanate coupling agent added is 0.02 to 25% by weight based on the metal powder, and the amount of the titanate coupling agent added is sufficient as long as it can coat the surface of the metal powder. There are no restrictions.
０．０２重量％以下であると均一に金属粉を被覆するこ
とができず、また２５重量％以上の添加は、効果におい
てあまり差が認められない。If it is less than 0.02% by weight, it will not be possible to uniformly coat the metal powder, and if it is added more than 25% by weight, there will not be much difference in the effect.
本発明の処理方法が優れた特性を有する理由については
、どのような機構で、どのような結合あるいは相互作用
をしているか充分明らかにはなっていないが２次のよう
なことが考えられる。The reason why the treatment method of the present invention has excellent properties is thought to be due to the following two reasons, although it is not fully clear what kind of mechanism and what type of bonding or interaction occurs.
少量のアルミニウム系カップリング剤で金属粉表面を予
め処理し、その後チタネート系カップリング剤で被覆す
ることにより、まずアルミニウム系カップリング剤と金
属が化学的に結合した保護被膜層が形成される。そして
チタネート系カップリング剤がその上から被覆された二
重処理膜が形成されていると考えられる。By pre-treating the metal powder surface with a small amount of an aluminum-based coupling agent and then coating it with a titanate-based coupling agent, a protective coating layer in which the aluminum-based coupling agent and the metal are chemically bonded is first formed. It is considered that a double-treated film is formed on which the titanate coupling agent is coated.
金属粉に対する表面改質の効果としてアルミニウム系カ
ップリング剤はチタネート系カップリング剤より耐熱性
、耐変色性において優れているが。As an effect of surface modification on metal powder, aluminum-based coupling agents are superior to titanate-based coupling agents in terms of heat resistance and discoloration resistance.
耐湿性において劣る欠点を有していた。しかし本発明に
よる処理方法であれば、おたがいのカップリング剤の長
所が生かされ、耐熱性、耐変色性。It had the disadvantage of being inferior in moisture resistance. However, with the treatment method according to the present invention, the advantages of each coupling agent are utilized, resulting in heat resistance and color fastness.
耐湿性に優れた金属粉が得られる。Metal powder with excellent moisture resistance can be obtained.
したがって、アルミニウム系カップリング剤を多量に添
加したり、アルミニウム系カップリング剤とチタネート
系カップリング剤を同時に添加して処理した場合には、
耐湿性に劣り、その使用に当り不都合が生じることがあ
る。Therefore, when a large amount of an aluminum coupling agent is added, or when an aluminum coupling agent and a titanate coupling agent are added at the same time,
It has poor moisture resistance and may cause some inconvenience when used.
