Description
本発明の他の目的は、応力除去焼鈍工程後にもボンディング力を維持できる接着コーティング組成物を適用した電磁鋼板製品を提供することにある。
芳香族炭化水素を含む樹脂は、後述する熱融着時、熱融着層を形成し、電磁鋼板の間に介在して、電磁鋼板の間に接着力を付与する。熱融着層が電磁鋼板の間で接着力を適切に付与できない場合、精密に積層された複数の電磁鋼板が工程の進行過程でずれてしまう。積層位置がずれてしまうと、最終的に製造された電磁鋼板製品の品質に薬影響を及ぼす。芳香族炭化水素を含む樹脂によって熱融着後、接着力を確保することによって、積層された電磁鋼板の位置がずれないようにすることができる。
無機ナノ粒子は、平均粒子サイズが3~50nmであってもよい。
無機ナノ粒子は、有機/無機複合体内に10~50重量%置換されていてもよい。つまり、有機/無機複合体100重量%に対して、無機ナノ粒子が10~50重量%および炭化水素を含む樹脂50~90重量%を含むことができる。無機ナノ粒子の量が少なすぎると、応力除去焼鈍後の接着層の接着力を適切に確保しにくいことがある。無機ナノ粒子の量が多すぎると、無機ナノ粒子が凝集する問題が発生しうる。
本発明の一実施形態による電磁鋼板積層体は、複数の電磁鋼板と、複数の電磁鋼板の間に位置する熱融着層とを含む。この時、熱融着層とは、前述した接着コーティング組成物を電磁鋼板の表面にコーティングし、硬化させて接着コーティング層を形成し、これを積層して熱融着することによって形成された層を意味する。熱融着過程で樹脂を分解させず、接着コーティング組成物内の樹脂を硬化させて熱融着層に接着力を付与する。このように、熱融着層は適切な接着力を確保することによって、積層された電磁鋼板の位置がずれないようにすることができる。熱融着過程で接着コーティング組成物内の溶媒などの揮発成分は除去され、固形分のみが残存するので、熱融着層は、接着コーティング組成物内の固形分と成分および成分比率が同一である。熱融着層の成分に関する説明は、接着コーティング組成物の説明と重複するので、重複する説明を省略する。
本発明の一実施形態による電磁鋼板製品は、溶接、クランピング、インターロッキングなど既存の方法を用いず、単純に前述した接着コーティング組成物を用いて接着層を形成することによって、互いに異なる電磁鋼板を熱融着させた製品である。
接着層30は、接着層30の断面面積に対して、気孔の占める面積の分率が0.5以下であってもよい。このように気孔の占める面積が少ないため、応力除去焼鈍しても水溶性有機成分が熱分解されて生成されるCO、CO2が完全に気化せず、炭化物または酸化物の形態で生成される。さらに具体的には、気孔の占める面積の分率が0.1以下であってもよい。さらに具体的には、気孔の占める面積の分率が0.01以下であってもよい。
接着層を形成する段階は、変性気体または窒素(N2)気体雰囲気で行われる。具体的には、変性気体は、液化天然ガス(LNG)10~30体積%および空気70~90体積%を含む気体を意味する。窒素気体雰囲気とは、窒素を含む雰囲気を意味する。具体的には、窒素100体積%の気体または窒素90~100体積%未満、および水素0超過~10体積%を含む気体を意味する。
接着コーティング組成物は、下記表1および表2に示しており、水溶性樹脂に置換されたナノ粒子の含有量は、水溶性樹脂の固形分100重量%対比、10重量%に固定し、粒子サイズは、置換されたナノ粒子の種類によって5nm~50nmである。電磁鋼板(50×50mm、0.35mmt)を供試片として準備した。下記表1および表2にまとめられた成分から構成された接着コーティング溶液を、Bar CoaterおよびRoll Coaterを用いて、各準備された供試片に上部と下部に一定の厚さ(約5.0μm)に塗布し、400℃で20秒間硬化した後、空気中でゆっくり冷却させて、接着コーティング層を形成した。
液安定性:各接着コーティング組成物を撹拌機によって30分間強く撹拌させた後、撹拌なしに30分間維持する。その後に、組成物内に沈殿やゲル(Gel)現象の有/無で判断した。
また、比較例12~比較例15では、複合金属リン酸塩を除いてリン酸のみから構成された組成を用いて、応力除去焼鈍(SRA)後の接着層の接着力に劣ることを確認することができる。
実験例1と同一に実施するが、接着コーティング溶液の成分および応力除去焼鈍条件を下記表4のように変更した。

20 酸化層
30 接着層
