【発明の詳細な説明】
（産業上の利用分野）
本発明は塗料あるいはライニング材に添加されるリン酸
系防錆顔料の改良に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to improvements in phosphoric acid-based antirust pigments added to paints or lining materials.
（従来の技術）
従来、塗料やライニング材に添加される着色用の顔料は
種々の目的のために表面処理して用いられることが多い
。表面処理の目的は一般的に分散性の向上、塗装表面の
光沢の向上あるいは真珠性光沢の付与等が挙げられる。(Prior Art) Conventionally, coloring pigments added to paints and lining materials are often used after surface treatment for various purposes. The purpose of surface treatment is generally to improve dispersibility, improve the gloss of the painted surface, or impart pearlescent luster.
また、顔料表面に酸化鉄や酸化クロム等の薄膜を形成さ
せ、機能性顔料を得ることも知られている。It is also known to form a thin film of iron oxide, chromium oxide, or the like on the surface of a pigment to obtain a functional pigment.
しかしながら、同様に塗料あるいはライニング材中に配

いで添加されている。However, anti-corrosion pigments (herein, anti-corrosion includes not only rust on metal surfaces in a narrow sense, but also deterioration of paint films, such as peeling of paint films), which are similarly blended into paints or lining materials. ) are added without substantially any special surface treatment.
（発明が解決しようとする問題点）
ところで、現在多用されている可溶性防錆顔料は塗料あ

種の防錆顔料は塗装置前に配合される場合もちるが、作
業性が悪くなる。(Problems to be Solved by the Invention) By the way, the soluble anti-rust pigments that are currently widely used may react with synthetic resins, etc., which are the main forming elements of paint or lining materials, or , for example, impairing storage stability. In addition, discoloration may occur due to these rust-preventing pigments. Therefore, although this type of anti-corrosion pigment can be added before painting, the workability becomes worse.
上記欠点はリン酸系の防錆顔料、−は、顕著になる場合

脂系塗料に配合した場合、貯蔵安定性が悪くなり、ウレ
タン樹脂系の塗料に添加した場合、硬化反応を遅らせる
ことになる。The above-mentioned drawbacks of phosphoric acid-based rust-preventive pigments may become noticeable. For example, 19. When end pigments are blended into engineered boxy resin-based paints, storage stability deteriorates, and when added to urethane resin-based paints, the curing reaction is delayed.
リン酸系の防錆顔料は塗膜中で侵入または拡散してきた
外部腐食環境因子の一つである水と反応してイオンを溶

しばこの溶出イオンの量が多すぎ、塗膜剥離や塗膜フク
レの原因となることもある。Phosphoric acid-based rust-preventive pigments react with water, which is one of the external corrosive environmental factors that has invaded or diffused into the paint film, to elute ions, thereby imparting rust-preventive properties, but they often If the amount of these eluted ions is too large, it may cause peeling of the paint film or blistering of the paint film.
現在、イオンの溶出の制御のために、リン酸系顔料の製
造時に焼成条件や組成条件を変更することが試みられて
いるが、未だ満足すべきものは得られていない。特に、
樹脂との反応性を抑制することは非常に難かしい。Currently, attempts are being made to change the firing conditions and composition conditions during the production of phosphoric acid pigments in order to control the elution of ions, but nothing satisfactory has yet been achieved. especially,
It is extremely difficult to suppress reactivity with resins.
従って、リン酸系の防錆顔料の上記欠点を有効に防止す
る方法が望まれている。Therefore, a method for effectively preventing the above-mentioned drawbacks of phosphoric acid-based antirust pigments is desired.

特に必要ない。Treatment with an aqueous solution containing iron ions is usually carried out by bringing the phosphoric acid pigment into contact with the aqueous solution containing iron ions, followed by washing with water and drying. The aqueous solution containing iron ions and the phosphoric acid pigment may be brought into contact by mixing the phosphoric acid pigment by blending the aqueous solution containing iron ions. Alternatively, a phosphoric acid pigment may be placed in a metal or glass column, and an aqueous solution containing iron ions may be poured into the column. For washing with water, for example, the contact-treated phosphoric acid pigment may be filtered and immersed in or brought into contact with deionized water. Washing and drying may not be necessary for certain applications.

と思われる。(Effects of the Invention) According to the present invention, since the treatment proceeds in an aqueous solution, the phosphoric acid released from the pigment reacts with iron ions, resulting in the formation of poorly soluble iron orthophosphate on the surface of the pigment. It is thought that a film as a component is formed on the surface of the phosphoric acid pigment. It is also believed that unreacted soluble iron phosphate is present in a part of this film.
この被膜がリン酸系顔料と樹脂成分を隔離するため、リ
ン酸系顔料の悪影響は実質上なくなるものと思われる。Since this film separates the phosphoric acid pigment from the resin component, it is thought that the adverse effects of the phosphoric acid pigment are substantially eliminated.

効に防止する作用を有する。Furthermore, phosphate ion leaching from water that has entered the coating continues as usual. In addition, soluble iron phosphate tends to react with OH- to form a precipitate, and since it reduces alkalinity, it has the effect of effectively preventing the peeling of the coating film that tends to occur in the alkaline region during corrosion.
