Abstract
Description
1) 20質量%未満の含水量で原材料を貯蔵することは問題を提示するので、爆発物として分類される。
2) 水性のニトログアニジンを含む添加剤の製造は、低い水溶性により複雑である。懸濁液は、安定剤を使用して最初に調製しなければならない。
3) 最後に、添加剤の貯蔵寿命は限られており、殺生物剤の添加が必須である。
R1R2R3C-NO2 (I)
(式中、炭素原子上の置換基R1、R2及びR3の各々は、他のものとは独立して、ヒドロキシメチル、1-ヒドロキシエチル、2-ヒドロキシエチル、1-ヒドロキシプロピル、2-ヒドロキシプロピル、3-ヒドロキシプロピル、1-ヒドロキシ-1-メチルエチル及び2-ヒドロキシ-1-メチルエチルからなる群から選択される)の少なくとも1種の促進剤を含む。
本発明の方法は、コーティングされていない金属表面、又は、例えば、予備リン酸塩処理を受けた、既に化成被覆されている金属表面のいずれかの処理に使用することができる。従って、以下の「金属表面」への言及は常に、既に化成被覆されている金属表面も含むとみなされる。
[OH-(CH2)n-]3C-NO2 (II)
(式中、3つのOH-(CH2)n-基の各々は、他のものとは独立して、n=1~3である)
の少なくとも1種の促進剤を含む。
1) 爆発物に分類されない。よって20質量%未満の含水量であっても原材料の貯蔵に問題はない。
2) 水溶性が良好である(最大で50質量%まで)ので、水性の促進剤を含む添加剤の製造が簡易である。促進剤は水に直接溶解する。従って、安定剤を使用して懸濁液を最初に調製する必要がない。
3) 最後に、添加剤の貯蔵寿命が長く、殺生物剤を添加する必要がない。
