RUST TREATMENT AGENT FOR GALVANIZED STEEL AND REPAIR METHOD USING THE SAME
PROBLEM TO BE SOLVED: To provide a rust treatment agent for application and a repair method using the same as a repair method alternative to replacement of members for prolonging life of equipment for a galvanized steel such as a steel tower member in which degradation due to rust becomes worse.SOLUTION: The rust treatment agent used for a rusted galvanized steel is provided which is composed of: a main agent containing (a) an epoxy resin, (b) acetyl acetone, (c) a rust preventive pigment, (d) an extender pigment and (e) a solvent; and a curing agent, and has a viscosity after mixing the main agent and the curing agent of 50 to 3,800 mPa s (20°C). The repair method using the rust treatment agent is also provided which includes performing chaplet treatment on the rusted galvanized steel to remove only weak rust, but not completely remove rust, and applying the rust treatment gent onto the resultant galvanized steel while a part of rust remains.SELECTED DRAWING: Figure 1
【課題】錆により著しく劣化が進行した鉄塔部材等の亜鉛めっき鋼材について、設備の延命化を図るべく部材の取り替えに代わる補修方法として、塗装用の錆処理剤及びそれを活用した補修方法を提供する。【解決手段】錆の発生した亜鉛めっき鋼材に用いられる錆処理剤であって、（ａ）エポキシ樹脂、（ｂ）アセチルアセトン、（ｃ）防錆顔料、（ｄ）体質顔料及び（ｅ）溶剤を含有する主剤と、硬化剤とから構成され、前記主剤と硬化剤とを混合した後の粘度が、５０〜３，８００ｍＰａ・ｓ（２０℃）であることを特徴とする。当該錆処理剤を活用した補修方法は、錆を有する亜鉛めっき鋼材面をケレン処理し、錆を完全に除去することなく脆弱な錆のみを除去した後、錆の一部が残存した状態で前記錆処理剤を塗布することを特徴とする。【選択図】図１
